     TECHNICAL FIELD 
     The present disclosure is generally related to wireless communications and, more particularly, is related to location tracking of wireless communications devices 
     BACKGROUND 
     For users of wireless network devices, concerns over privacy are well founded, especially when considering the increasing convergence of wireless communication networks with global computer networks. Wireless networks are now routinely in communication with the global computer network, providing network users with expanded services such as Internet access through their wireless handheld devices. Through this same link, wireless network providers can provide third parties, such as advertising web sites, with the identity and location information that the network provider is (or will be) required to monitor. (As used herein, third party refers to a participant in a transmission other than the wireless handheld device and the wireless network with which the device communicates.) Consequently, third parties would be able to identify a network user and track that user&#39;s every movement. Although these third parties may claim that such information merely enables them to profile customers and to present more individualized products or services, a significant portion of network users would agree that such practices are a clear invasion of privacy, ripe for abuse. 
     Third parties, such as advertisers, may attempt to target users that are sent information from a third party based upon a user&#39;s location. Targeting users with information from third parties, such as advertisers, is challenging particularly when the user is active and the information is being sent to a mobile communication device.

     DETAILED DESCRIPTION 
       FIG. 1  illustrates a system architecture  100  linking a wireless network  110  to a computer network  112 . As shown, the wireless network  110  is in communication with a plurality of wireless devices  114  through computer network  112 . The wireless devices  114  may include any apparatus that can establish a wireless communication session via a wireless communication link. Common examples of the wireless devices  114  include cellular telephones, cellular telephones with text messaging capabilities, personal digital assistants (PDAs) such as the Palm Pilot™, wireless telephones, a computer and interactive text pagers. 
       FIG. 1  illustrates that a wireless device, such as a cell phone,  114  is in wireless communication with the computer network  112  using, for example, radio channels for voice and/or data communication. It is noted that the term “wireless network,” as used herein, is contemplated to include analog or digital cellular mobile networks irrespective of the underlying transmission technology, e.g., CDMA (code division multiple access), TDMA (time division multiple access), WIFI (wireless fidelity), etc. In some non-limiting embodiments the wireless network will be a radio network that employs intersystem messaging (e.g., the IS-41 based messaging scheme) as part of mobile wireless communication, while in other non-limiting embodiments intersystem messaging will not be used. Also, wireless networks further may include wireless data technologies such as but not limited to Aloha, WiFi, WiMax, and BlueTooth, which are capable of wirelessly carrying data in various forms including ethernet frames and/or Internet Protocol (IP) datagrams. The wireless network  110  may include a combination of one or more of, for example, an analog wireless network (e.g., the AMPS (Advanced Mobile Phone System) network), a digital wireless network including cellular networks (e.g., TDMA or CDMA-based wireless networks), a wireless LAN (Local Area Network) such as but not limited to WiFi/IEEE 802.11, a wireless broadband network such as but not limited to WiMax/IEEE 802.16, a WLL (Wireless Local Loop), and a near field wireless technology such as a Bluetooth configuration. A portion of the wireless network  110  may include one or more microwave links for satellite-based communication. 
     An example of the computer network  112  is the Internet. A location server  120  communicates with the computer network  112 . The location server  120  stores location information about a user or a plurality of users of the wireless devices  114  and provides location information to a requesting and authorized user. The location server  120  may receive information that identifies a current location of a user, or the location server  120  may receive information from which, fully or in part, the location server  120  can determine a current location. A third party server  150 , in some embodiments, receives location information from the location server  120 . 
     Communication amongst location server  120 , third party server  150 , and computer network  112  may be via either wireless communication link or wireline communication link, or both. The session may be a voice or a data session, or both. Furthermore, the session may use one of several technologies, including but not limited to analog, digital, fixed bandwidth, variable bandwidth, constant bit rate, packetized data. Voice communication sessions may use one or more of many different CODEC (coder/decoder) standards such as but not limited to μ-law G.711 speech, a-law G.711 speech, G.723, G.729, as well as many other voice encoding technologies that are known by one of skill in the art and are used in analog and digital carriage of POTS/ISDN voice over the PSTN and also used in carriage of VoIP over an IP network. 
     Whether for monitoring the whereabouts of children as a safety check or for tracking the productivity of employees in a business, tracking and monitoring systems for detecting an individual&#39;s location and movement allow one to easily and more effectively supervise others from a remote location. 
     When the wireless device  114  is in operation, the wireless network  110  tracks the location and identity of the device  114 . The plurality of wireless devices  114  provides the wireless network  110  with their identities, typically as mobile identification numbers (MINs) or through other identification (ID) and addressing techniques such as, but not limited to, phone numbers, E.163 and/or E.164 addresses, X.121 addresses, IP addresses, MAC (media access control) addresses, URLs (universal resource locators), email addresses, and/or LDAP (lightweight directory access protocol) or other directory database name labels and tokens. For tracking a location, individual location systems  115  in the wireless devices  114 , a network-based location system  111  within wireless network  110 , or a combination of both systems  115  and  111  may be used to track a user&#39;s location. As an example, a network-based location system may calculate triangulation across cell sites or cell sectors to determine a location of a wireless cellular handset. 
     Accordingly, the geographical location for a wireless handheld device, such as the wireless device  114 , may be determined according to a variety of methods. Generally, these methods utilize control signals that are emitted and received by the wireless devices  114 . As shown in  FIG. 2 , mobile cellular telephone  114  is located near cell towers  221 ,  222 , and  223 , and is closest to the cell tower  221 . The cell towers  221 ,  222 , and  223  may be spaced one to five miles from each other, depending upon the amount of cellular use in a given area. In  FIG. 2 , each of the cell towers  221 ,  222 , and  223  receives control signals from cellular telephone  114 . For cell tower  221 , this information is sent to a mobile switching center (MSC)  225  through cell control  224 . Cell tower  221  also broadcasts control signals sent from the MSC  225 , which are then received by wireless devices  114 . The control signals are used for registering that the wireless device  114  is operating within a cell, so that the wireless network  110  can establish a communications link between the cell tower and the device  114 . 
     One method for determining the geographical location is to identify the cell tower, such as the cell tower  221  that is physically within the closest proximity to the device  114 . (Also, the closest WIFi, WiMax, and/or Bluetooth access point may be determined using similar techniques, and triangulation techniques can be further employed to more accurately determine location using multiple WIFi, WiMax, and/or Bluetooth access points.) By determining which of the cell towers  221 ,  222 , or  223  is closest to the mobile cellular telephone  114  and providing this information along with a mapped display on the Internet, an authorized user can find a cellular telephone user&#39;s location within a range of approximately three miles. This can be performed by forwarding “registration” information that is temporarily stored within the MSC  225  to the network-based location system  111  in  FIG. 1 . Another technique for identifying the cell tower, such as the cell tower  221 , closest to the wireless device  114  is to use a “mobile maintenance command signal.” The mobile maintenance command sends out a paging request signal to be received by the mobile telephone  114 . The mobile maintenance command is sent to all cell sites in the system, or can be sent to the last known cell site based on registration over the paging channel. The mobile  114  is then paged (called) with a modified signal that tells the mobile phone  114  to respond, but does not alert (ring). The mobile phone  114  then responds back. Every cell nearby will receive the mobile&#39;s signal and forward the response to the network-based location system  111 . Based on RSSI (received signal strength indication), the mobile phone  114  is determined to be closest to a particular site in the system. 
     The geographical location of the wireless device  114  can be determined with greater detail by using cell tower triangulation. In this method, the network-based location system  111  determines the location of the wireless device  114  by comparing the signal strength of the control signals emitted by the wireless device  114  received at antennae at several neighboring cell towers  221 ,  222 ,  223 . The signal strength is strongest at the nearest cell tower  221 . A diminished signal is received at other cell towers  222 ,  223  in the vicinity. The differences in signal strength can be used to calculate the location of the wireless device  114 , at least within 200 meters. Cell tower triangulation algorithms are presently being used and refined for E911 emergency services. 
     An example of the individual location system  115  would be a Global Positioning System (GPS). Some wireless devices  114  currently incorporate a GPS receiver  116 , such as GPS receiver chips, to receive location information by satellite. By connecting the GPS receiver  116  in the wireless device  114  to the communication equipment within the wireless device, the GPS geographical information can be forwarded to the location server  120  for access by an authorized user. 
     Cellular telephones, interactive pagers, and personal digital assistants each have a liquid crystal display (LCD) that can be used with the monitoring system of the present disclosure to notify the individual that they are being monitored. Many wireless communications devices, such as the devices  114 , include a text messaging feature to allow the users to receive e-mail messages or any other type of short text messages on the LCD display. 
     To track the location of wireless device  114 , the system architecture  100  can include one or both of network-based location system  111  and device-based location system  115 . Network-based location system  111  may be a component of wireless communication network  110 . Device-based location system  115  may be an integrated part of the wireless device  114 . One or both of network-based location system  111  and device-based location system  115  can generate location information pinpointing the location of the wireless device  114 . In some embodiments, both location systems  111  and  115  are compatible with the Geographic Information System (GIS) and the GPS. The device-based location system  115  may be the GPS receiver  116  that is in wireless communication with a constellation of GPS satellites. In some embodiments, both location systems  111  and  115  can be used to provide redundancy, accuracy, and reliability. The location information may comprise point coordinates pinpointing the location of wireless device  114 . The point coordinates can include an X component and a Y component of a coordinate system. According to exemplary embodiments, the location information comprises a longitude and a latitude. For increased accuracy and granularity, the location information can further comprise an altitude. In some embodiments, the location information can pinpoint the location of the wireless device  114  to within 125 meters, as required by the E911 mandate. 
     In some embodiments, location server  120  is compatible to one or more of GIS (Geographic Information System), GPS (Global Positioning System), and WAP (Wireless Application Protocol). The location server  120  can receive the location information from one or both of the location systems  111  and  115 . The location server  120  can also receive identity information of wireless device  114 . The identity information may comprise, for example, a serial number of the wireless device  114 . As previously mentioned, the identity information may also be a MIN of the wireless device  114 . The location server  120  may be a network-based component, as shown in  FIG. 1 . In other embodiments, the location server  120  may be a portable unit that is part of the wireless device  114 . Therefore, the wireless device  114  may comprise none, one, or both of the location server  120  and the location system  115 . 
     As discussed above, in some embodiments, among others, the location server  120  and location systems  111  and  115  can be WAP compatible. WAP is an application environment and set of communication protocols for wireless devices designed to enable manufacturer-, vendor-, and technology-independent access to the computer network  112  and advanced wireless telephony services provided by the wireless communication network  110 . 
     WAP provides wireless Internet access through digital cellular networks, giving network users a menu driven method for downloading information, such as flight schedules and bank account balances, to wireless devices, such as the wireless devices  114 , from the computer network  112 , such as the Internet. WAP is described in WAP version 1.1, which is herein incorporated by reference in its entirety. 
     As part of determining the location information, the location server  120  processes the control signal information emitted and received by the wireless device  114 . The type and amount of formatting necessary depends upon both the method utilized for determining the geographical location of the wireless device  114  and the type of information to be supplied to the authorized user. As an example, if the location is determined solely according to the identity of the closest cell tower, such as the cell tower  221 , the network-based location system  111  is forwarded a code identifying the cell tower. The code is then translated through a look-up table into a geographical address, which may include information such as a street name, street intersection, county, or township. If the location is determined by the triangulation method, the calculated data is converted into geocoded location coordinates that are compatible with standard mapping software. If GPS information is communicated from the wireless device  114 , the network-based location system  111  merely decodes the communications signal and passes the information along to a location database  140  which stores location information. 
     In one embodiment, an implementation of the system of  FIG. 1  involves the location information for a user being tracked by a third party and based on the user&#39;s tracked location information, the third party sends information to the user that is determined to be of interest to the user. It is noted that targeting users with information from third parties, such as advertisers, is challenging particularly when the user is active and the information is being sent to a mobile communication device, such as the wireless device  114 . The aforementioned implementation addresses these concerns. 
     Accordingly, a location of the user associated with the wireless device  114  is provided to the location server  120  from location system  111 ,  115 . In one embodiment, the location system  115  within the wireless device  114  provides a current location to the location server  120 . A variety of ways may be used to acquire location information. For example, as discussed above, the GPS receiver  116  that is part of the wireless device  114  may acquire GPS coordinates and provide these coordinates to the location server  120 . The location server  120  may then allow a third party to access the user&#39;s location information. In this example, the third party server  150  receives location information about a user from the location server  120 . 
     The third party server  150  may be GIS, GPS, and WAP compatible. In some embodiments, the third party server  150  can receive the location information from the location systems  111  and  115 . The third party server  150  can also receive identity information of the wireless device  114 . The identity information may comprise, for example, a serial number of the wireless device  114 . The identity information may also be a mobile identification number of the wireless telephone  114  or other forms of identifying information such as but not limited to phone number, customer number, a person&#39;s name, an email address, etc. 
     Using the location information and the identity information of the wireless device  114 , the third party server  150  can be adapted to execute a large number of actions according to operating rules, instructions, or preferences provided by a user of the device  114 . For example, in an embodiment involving wireless telephony in which the wireless device  114  is a wireless telephone, the third party server  150  could use the location information and the identity information to request that the user download a ringtone corresponding to a user&#39;s current location and/or customize the user&#39;s wireless device  114  to match an event occurring at the user&#39;s current location. 
     Alternatively, or in combination with, the location system  115  in the wireless device  114 , the wireless device may include an RFID reader  117  that detects the presence of a nearby RFID tag, such as an RFID tag on the electronics section of a department store. The RFID reader  117  communicates with the RFID tag and receives an identifier for the tag and an address for communicating with the third party server  150 . The location system  115  transmits the RFID identifier to the third party server  150  (or a gateway  190  of third party server  150 ). Additional information may be transmitted such as an indication that the third-party server  150  is or is not accessible over a WiFi network within the department store. A WiFi, WiMax, or Bluetooth network within a store or a mall may have multiple WiFi, WiMax, or BlueTooth access points to ensure adequate coverage of the area, and the closest WiFi, WiMax, or Bluetooth access point to a customer may be determined to provide additional information about a customer&#39;s location. Via this type of location tracking, a specific position of the wireless device  114  may be pinpointed within a small area, such as a particular section or aisle of a store. Also, in some embodiments, an RFID tag may be positioned on the user&#39;s wireless device  114  and the reader  117  positioned in a particular location, so that when the reader detects the wireless device  114 , the reader can relay to the third party server  150  that the wireless device  114  is in the area. 
     The third party server  150  may communicate with the location database  140  and other databases, such as a third party database  170 , to determine interests of the user. For example, the amount of time that the user has visited the current location may be provided to the third party server  150  from the third party database  170 . Further, the past customer purchases of the user of the type offered in the visited area may be provided to the third-party server  150 . Accordingly, the current location information is also stored in the location database  140  by the location server  120  for future use, according to exemplary embodiments. By tracking movement of the user, a potential interest of the user based on the user&#39;s commonality in time in searching for specific types of goods and services may be attempted to be determined by the third party server  150 . In some embodiments, instead of the location database  140  being stored on the computer network  110 , the location database  140  may be maintained internally by the wireless device  114 . 
     The third party server  150  can receive a user&#39;s location information and forward location-dependent messages. As an example, the third party server  150  of a content provider could provide alerts or content (e.g., advertisements) to the wireless device  114  when the device moves into a targeted area (e.g., a particular area within a store of a shopping mall, including a particular aisle as opposed to the adjacent aisle). 
     In some embodiments, additional data can be used to determine a potential user or customer&#39;s interest in goods or services offered in a current location. For example, the characteristics of the tracked locations and movement of the user may be compared against monitored locations and movement of previous users and their resulting actions (e.g., whether those types of movements resulted in purchases of goods and of what type). Accordingly, content may be sent to the wireless device  114  from the third party server  150  to facilitate transactions which are determined to be of potential interest to the user. According to exemplary embodiments, an indication of interest in a particular good or service is a function of historical data such as types of items for sale at locations, frequency of visits to location types, duration of visits or individual visit over a period of time, items or services purchased, demographics of user, user profile, complementary and substitute items purchased, etc. This information may be stored as part of the third party database  170 . Alternatively, in some embodiments, a user database at the wireless device  114  may maintain historical data. 
     Therefore, the indication of user interest may be qualified based on time spent in a first area of a locale, such as a store, a mall, amusement park, sports arena, etc. Accordingly, the first area may be a store, building, shopping mall, store aisle, vehicle, geographic boundary, etc. The indication of user interest may be further qualified based on time spent in a second area of the locale. For example, if a user spends twice as much time in a second area of a locale as a first area, it may be assumed that the user was more interested in the second area than the first area. The indication of user interest may further be qualified based on demographics, activities observed in the first area, etc. Such activities may include purchases, inquiries, demos, returns, customer browsing, selection, and showing interest. Based on the determined indication of user interest, an advertisement may or may not be sent to a user by the third party server  150 . The advertisement may be one of a coupon or directions to potential items of interest. In one embodiment, the advertisement is delivered to a portable communications device for the user which may or may not be the wireless device  114 . Historical data may include acquired information from multiple locations of a store or similar establishment (e.g., restaurant, park, etc.), specific locations in a store or similar establishment, a time period beyond one day, etc. 
     As an example, one embodiment of a third party monitoring system (which utilizes components of  FIG. 1  such as location server  120 , location database  140 , third party server  150 , third party database  170 , and wireless device  114 ) may track a person&#39;s movements throughout the day and record location information indicating that the user has been to five different car dealerships. The third party monitoring system derives from the user&#39;s habits that these trips to the dealership were unusual and thus determine the user was clearly interested in a car. For example, the third party monitoring system accesses the user profile from the third party or store database  170  to determine preferences and, from the store database  170 , checks the date of the last car purchase by the user. From this information, the third party monitoring system pushes an advertisement of a new family car with directions to the nearest FORD dealer (could be any auto dealer). Therefore, the third party monitoring system selects an action (e.g., sending advertisement and/or directions) to perform based on the user&#39;s predicted interest. 
     In another example, an embodiment of a third party monitoring system performs tracking by obtaining a list of establishments the user has visited (from the third party database  170 ) as opposed to location coordinates. This may provide more privacy for the user since the third party monitoring system would not share visits to residential locations or other locations designated by the user as private. In this scenario, the third party monitoring system might ascertain that the user visited a travel agent and the Mexican tourist office and conclude the user is planning a trip to Mexico. Based on this prediction, the user might receive information coupons, hotel information, and other related travel related information to his or her wireless device  114  or some other communications device associated with him or her from the third party server  150 . 
     In another scenario, the third party monitoring system could also provide information regarding a child or spouse&#39;s activities. For example, the third party monitoring system might notify the parent that the child appears to be shopping based on locations that the child is visiting that are received by the third party server  150  from the location server  120 , according to the child&#39;s visits to various locations. Note the system might differentiate visited location verses passed locations by time spent in the location or provide greater weighting based on time spent in a location. 
     In a store, an embodiment of a third party monitoring system could track a user&#39;s movement and determine the user&#39;s shopping needs/interests. For example, the user could go into a sports store and look at fishing boats for a period of time. After which, location information is provided to third party server  150  from the location server  120 . The third party server  150 , based on the received information, might then suggest, by sending the user a text message to the wireless device  114  of the user that the user look at the sale on fishing rods at the back of the store. The message might include directions or a coupon or a video. 
     Accordingly, a method of using location history to optimize communications with perspective customers, as illustrated in  FIG. 3 , may include tracking ( 310 ) movement of a user (using one or more of the location server  120 , wireless device  114 , and the third party server  150 ) to determine potential interest of a user based on user&#39;s commonality in time in searching for specific types of goods and services. The method further comprises analyzing ( 320 ) a user&#39;s location history over a limited period of time (by the third party server  150 ) and detecting ( 330 ) (by the third party server) an indication of user interest in sellable items, as further represented in the flowchart of  FIG. 3 . 
     In one embodiment, a third party monitoring system can determine that a person has gone into one particular store (e.g., a consumer electronics retailer) within the last few hours. Based on that information, another store of the same type (e.g., a consumer electronics retailer) could send an alert or coupon to the customer based on a inference of determining that the customer is likely shopping for some type of consumer electronics. The temporal locality (or commonality in time) of a customer visiting similar kinds of stores within a reasonable period of time may be an indication that a customer is shopping for a particular kind or type of good or service. 
     Similarly, a customer within a store who spends a relatively significant amount of time on a single aisle in the store or in front of a single display is likely looking to purchase something on that aisle or in the display. For example, a person that spends five minutes in front of the hot dog freezer in a grocery store may be a good potential customer to offer a coupon or other incentive to buy complementary goods (such hot dog buns, mustard, ketchup, relish, potato chips, etc.) and substitutes (such as hamburgers, sausage, etc.). Unlike ads/coupons at the time of purchase, sending ads/coupons to a customer&#39;s mobile device  114  based on the behavior of a customer in the store allows the ads/coupons to reach the customer before he/she has gotten into the check-out line. 
     According to exemplary embodiments, a location sensor  118 , such as the GPS receiver  116  or RFID reader  117 , in the wireless device  114 , collects location information and relays the location information to the location database  140  (e.g., via location system  111 ,  115 ). The location sensor  118  and location database  140  may be in a network or in a mobile device, such as the wireless device  114 . In particular, the location sensor  118  and the database  140  may be in a network location remote from the wireless device  114  of a user. In another embodiment, the location sensor  118  and database  140  may be part of the wireless device  114  of a user. The location database  140  contains data, such as a history of locations visited by the user. 
     Additional data may be stored that is used to determine potential consumer interest in a good or service offered by a store visited by a user. This additional data may be stored at a user database in the wireless device  114  and/or stored at the third party database  170 . This information is used to predict a user&#39;s interest in a good or service by the third party server  150 . For example, an indication of interest may be a function of: type of items for sale at location, frequency of visits to location types, duration of visits or individual visit over a period of time, items or services purchased, demographics of user, user profile, complementary and substitute items purchased, demos, inquiries, returned items, etc. Also, the third party server  150  could associate group activities and the behavior of group members with the user, such as family members, company employees, church groups, etc. Statistical analysis/modeling techniques may be used by the third party server  150 , such as, regression analysis, Bayesian analysis, trend analysis, forecasting, etc. 
     Such a third party monitoring system may be implemented in the third party server  150  or in an application on user device  114 . Location information may be combined with recent or prospective sales information (from universal product code (UPC), cash register, RFID, etc.) which allows add-on sales opportunities for advertising while in the store or when a customer leaves or enters the location of a store. The location information provides improved e-commerce opportunities for stores and also allows better advertising that is more accurately targeted to consumers who are more likely to purchase a particular produce or service. The targeted ads may include structured content comprising one or more of the following images, video, audio, text, multimedia, etc. Personalized location information for store customers (or other automatic identification means such as facial recognition) allows a store to immediately recognize that a preferred or high-volume customer has entered the store so that sales representatives can offer excellent service to the big spending customer. 
     In some embodiments, other types of information may be sent to a user based on the user&#39;s location. To make cell phones  114  and other communication devices more user friendly, an alert function may be defined by some other party besides the end user and tied to a particular location. Therefore, unique alert functions may be associated with specific locations. 
     As an example, when a user enters a basketball arena his or her communications device  114  may receive a request to load a customized ringtone/theme from a third-party server  150  based on one of the teams playing in the basketball game.  FIG. 4  shows such a message that may be received on a user&#39;s wireless device  114 . In the message, it invites a user to download a ringtone for one or both of the teams competing in that day&#39;s basketball game. The message also indicates that a monetary charge is made for downloading a ringtone. 
     Ringtone data and theme data generally are files which affect the operation and appearance of the communication device  114  during operations. A ringtone can include video, image, and music depending on phone capabilities. A theme may be a combination of altering tone and desktop image(s), menu style, key style, device sounds (such as when typing or sending an email). Accordingly, desktop background, window appearance, operating system functions, in one embodiment, are all affected when a new theme is implemented. 
     Depending on the setting to the communications device  114 , the device might block these messages, alert the user of the new options, or automatically select and install the recommend ringtone/theme. Upon leaving the stadium, the phone  114  reverts back to its default ringtone, in some embodiments. 
     In another example, when a user enters a specific location, for example a Tower Record store, the store or the service provider could use the third party server  150  to push to the user&#39;s communications device  114  a new set of alerting tones or themes which a user could select from a menu list. There might be a fee associated with acquiring one of these ringtones/themes. 
     In one embodiment, the third-party server (“ringtone/theme server”)  150  uses rules to select one or more ringtones/themes to present to the remote communications device  114 . The server  150  uses the location of the communications device  114  along with user profile information (from the third party database  170 ) and device capabilities, when available, to determine what, if any, ringtone/themes the server could communicate to the communications device  114 . 
     In some embodiments, the gateway  190  provides the transformation and interface to the remote communications device  114  and the server  150 . According to exemplary embodiments, the gateway  190  handles the various configuration sub-systems for cell phone alerting control systems of multiple service providers. In some embodiments, the gateway  190  is not required, or the gateway&#39;s functionality is incorporated into the third party server  150 . 
     According to exemplary embodiments, the location server  120  provides the location information regarding the remote communication device  114 . The location information can be provided through the network location system  111  or the device based location system  115 , such as, GPS, as discussed above. 
     In one embodiment, a location tracking method would work as follows, as depicted in  FIG. 5 : (1) the communication device  114  reports its location to the location server  120 ; (2) the location server  120  sends location information to the gateway  190 ; (3) the gateway  190  passes location information with additional information on the user and type of the device  114  to the R/T (ringtone/theme) server  150 ; (4) the R/T server  150  does a lookup in the R/T database  170  based on location, user profile and device to select alert message; (5) the R/T database  170  provides list of ringtones and themes based on information provided by the R/T server  150 ; (6) the R/T server  150  sends a message to the gateway  190  with ringtones/themes from the database  170 ; and (7) the gateway  190  sends the message to the remote communications device  114 . 
     Depending on the configuration of the remote communications device  114 , the device can alert a user to available ringtones/themes or could automatically implement recommended ringtone/theme. 
     Additional device or service features may also be adjusted by a third party or by the wireless device upon the wireless device or the network determining that a geographic boundary threshold has been crossed. Device and/or service features that may be adjusted include but are not limited to information such as alerting ring tone, buzzer, vibration, video, flashing lights, text message, altering audio channel (such as but not limited to speaker or ear phone) based on the location of the called party and/or the location of the calling party. Furthermore, these services and/or features can be stored locally on the mobile device, stored in the wireless network, or stored in a combination of the mobile device and the wireless network. For instance, calls from a person at college stadium on game day could have a pushed ring tone of the college team fight song. Calls to a teenager at school could play the latest rap song when at school and play a standard ring tone when at home. In this way, a teenager&#39;s ring tone may be changed from the latest music with lyrics that might offend parents to more mellow music whenever the teenager is at home. A person&#39;s ring tone may change from a professional non-descriptive ring to more personality defining movie lyrics whenever the person leaves the office. Calls to a person in a movie theater can be automatically muted and switched from audio to another mode such as vibration. Prioritized, urgent, and emergency calls may not have the alerting signal changed, when regular or standard calls may yield control of the alerting type to the movie theater to automatically switch the standard or regular alerts for all phones in a theater to vibrate. A remote cell phone, such as the wireless device  114 , could compare its known current location against a database of geographic zones for various business types to determine that the phone has entered a movie theater. Then, the alerting type could be automatically changed to vibration from an audible ring. Remote devices could allow a public mode that allows movie theaters, libraries, schools, etc. to adjust the alerting mechanism for non-priority calls (such as from friends) as opposed to family emergencies. 
     Priority levels could control for which calls the third party would be allowed to change the alerting signals when a person enters the geographic zone of the third party (such as a school, library, theater, etc.). A public mode may be managed using a security code for authentication. In one embodiment, user interface screens provided on the wireless device  114  may allow a user to select individuals from the user&#39;s “buddy” or contact list as having a privacy mode that does not allow for device features to be adjusted when communication is commencing with these individuals, as reflected in  FIG. 6 . 
     Alerting tones can change based on location, and the changes can include more options than just mute, vibrate, and audible sound. Tone changes based on location can be changed from one audible tune to another audible tune or from a tune at a high volume level to the same tune at a low volume level. As previously discussed, the portable electronic device  114  is capable of knowing its location through GPS, wireless network information such as beacon transmitted identifications, and/or near field wireless communications, according to exemplary embodiments. 
     In one embodiment, a method of using location information to push alerting information to the communications device  114  comprises receiving ( 710 ) location information regarding the communications device  114  (at the third party server  150 ); selecting ( 720 ) alerting information based on the location of the communications device  114  (by the third party server  150 ); and transmitting ( 730 ) to the communications device  114  information pertaining to the alerting information (by the third party server  150 ), as depicted in the flowchart of  FIG. 7 . In some embodiments, the information that is transmitted may be dependent on the operating rules of the communications device  114  or user. Further, a third party transmitting the alerting information may be authenticated before acceptance of any information. The types of transmitted may include sound, music, alert tone, video, image, or a theme. Further, transmitted information may change the alerting setting in the communications device  114  to a new nonsilent setting. 
     Operating rules, instructions, or preferences may be specified by the user or created by the third party server  150 . The operating rules may be provided to the third party server  150  via a number of channels. For example, the operating rules may be keyed in by the user or other persons using a keypad on the wireless device  114 . Alternatively, the operating rules may be provided via wireless communications network  110  and/or computer network  112 . Operating rules may stipulate that features involving a phone call from a user&#39;s parents should not be affected. 
       FIGS. 8-9  show exemplary interfaces from the wireless device  114  that are used to select locations where device features may be adjusted, in one embodiment. In the illustration of  FIG. 8 , an interface is provided for a system utilizing the GPS receiver  116  as the location sensor  118 . The user checks the boxes next to locations where the user opts to let features be adjusted when the user visits a location of the selected type. Similarly,  FIG. 9  illustrates the same interface that is used in a system utilizing the RFID reader  117  as the location sensor  118 . 
     Wireless network providers can provide third parties, such as advertising web sites, with the identity and location information that the network provider is (or will be) required to monitor. Further, wireless networks  110  can provide location information to scheduling applications and/or other software applications. For example, based on a person&#39;s current location and planned itinerary of business meetings, plane reservations, dinner reservations, etc., a software application using the information may infer that a user is not likely to make a scheduled appointment and either automatically reschedule the appointment or notify the user to determine whether the user wants to reschedule the appointment by bringing up a voice, video, data, or web page connection into the appointment reservation system to allow the user to pick a new time. 
     As another example, if a parent could set a curfew time for a teenager, a third party monitoring system could notify the parent if the teenager will not make it home on time or the system could notify the teenager when he/she must leave for home (based on distance from home as well as expected traffic delays and travel time) in order for the teenager to make the curfew. Similar notifications could be used to tell a person when to leave for a plane, office meeting, or other appointment. 
     Additional examples include automatically changing a ring tone/alerting sound automatically based on at least location information and possibly other factors such as time of day, day of week, etc. The alerting form can be other characteristics instead of or in addition to sound such as but not limited to visual indicators, vibrations, etc. that may flash or vibrate differently or in particular sequences based on location information. 
     Furthermore, the control of alerting sounds and other indicators (such as flashing and/or vibration) can be passed to a third party. The security control that authorizes a third party, such as but not limited to a church, a school, and a movie theater, to change alerting types, alerting signal amplitude levels, and alerting information signals can be based on an identifier for the church, school, movie theater, etc. plus a location range in which security is relaxed to allow the church, school, movie theater, etc. to change a cell phone or other portable electronic device from ring to vibrate. Outside of that geographic zone, the identifier for the church, movie theater, etc. would not have the authority to change a mobile device&#39;s alerting type, according to exemplary embodiments. 
     Also, the relaxation of a mobile device&#39;s security within a geographic area (such as a movie theater) may allow a mobile device to be switched from ring to vibrate based on any command to change modes from ring to vibrate that is received by the mobile device without requiring identifying information from the transmitter of the muting/vibrating command request. Based on a message from wireless equipment at the movie theater or church, the mobile device can use a learning mode to initially prompt a user by asking whether to allow the movie theater or church to have security access to change the alerting type for the mobile device. In addition to a location-based constraint on the security relaxation (as well as potentially an identifier-based constraint), the security rules may have an expiration time of two and half hours at the movie theater or an allowable control time window of one hour every week during church services. 
     Each business or entity (such as but not limited to: movie theaters, libraries, schools, churches, etc.) could have a different authentication identifier (ID). In a non-limiting embodiment, the wireless device may only allow the movie theater authentication ID to change the alerting settings of the wireless device when the wireless device is in the geographic location of the movie theater. As an example, when the movie theater authentication ID first asks for permission to change the alerting settings on the wireless device, the movie theater request message may include coordinates of the vertices of a polygon circumscribing the movie theater or the coordinates of a center plus a radius describing a circle containing the movie theater. The wireless device can compute the approximate area size over which the movie theater is requesting to control the wireless device&#39;s alerting settings to then inform the user of the wireless device with a reasonable estimate of the location range over which the user is surrendering security control of the alerting settings of the wireless device to the movie theater&#39;s authentication ID, which would be contained in the request message sent from the movie theater to the wireless device. 
     Further, in one embodiment, the wireless device  114  may receive transmissions identifying the current location, such as transmissions from an RFID tag or a WiFi beacon. Accordingly, based upon the received information, the wireless device  114  may ascertain the type of location being visited (e.g., a church) and then correspond by changing device settings in response to recognition of the new location. 
     In one embodiment, location information may be provided to the third party server  150  so that an application can track and update the status of events associated with a plurality of users, as illustrated in the flowchart of  FIG. 10 . For example, in one embodiment, a meeting program  165  hosted or embedded on third party server  150  or application server  160  enables a user to invite ( 1010 ) other users (“potential attendees”) to participate in an event, such as a scheduled meeting. Invites are sent ( 1020 ) by the meeting program to the potential attendees. Via the meeting program, the potential attendees may accept or decline ( 1030 ) the meeting invite or request. The meeting program can inform the user that made the request with the status of the meeting, such as who accepted or declined the meeting request. Additional information may also be tracked however. For example, each of the potential attendees may have a tracking device, such as GPS equipped phone  114  that is identified in the third party database  150 . The meeting program may access the third party database  170  to receive the identification number for a potential attendee&#39;s tracking device, such as the wireless device  114 , and request the attendee&#39;s current location from the location database  140 . Therefore, as the meeting time approaches, the meeting program can ascertain ( 1040 ) which of the attendees that accepted the meeting request are close to or have arrived at the meeting location which is known to the meeting program. Further, the meeting program can identify ( 1050 ) the number of potential attendees that have arrived at the meeting location. The meeting program can provide ( 1060 ) reports or estimates of whether a particular person is expected to arrive at the meeting location before the meeting commences. Accordingly, the meeting program can also alert ( 1070 ) a potential attendee to inform the attendee that he or she is not on track to make a scheduled meeting before the meeting&#39;s start time so that the user can make attempts towards progressing to the meeting location, if he or she is not on his or her way. 
       FIGS. 11-13  illustrate exemplary graphical user interfaces for a monitoring system for use as a meeting monitor according to one embodiment. A user, in this case, a meeting organizer or initiator, can access the graphical user interface using a desktop or laptop-type computer system  198  having an Internet connection to the world wide web, using Internet browser software. As provided in  FIG. 11 , upon connecting to the Internet or to a corporate (or other entity&#39;s) Intranet and entering the appropriate URL to access the monitoring website, the user enters an access code for the meeting. The user may then be presented with a list of names of persons who the user is authorized to monitor. These may be users that the meeting organizer has invited to attend a meeting. In this example, the user is authorized to monitor the wireless devices  114 , such as mobile telephones carried by potential attendees of a meeting. The list provided to the user indicates whether the wireless communication device  114  for each of the individuals is on or off. From this list, the user selects which of the individuals to monitor. A meeting organizer in this example selects to monitor each of the users that have indicated that they are to attend a meeting planned by the organizer. Using the scheduled event time, meeting location, and list of attendees, it may be determined who has arrived and who has not at the meeting location and/or the estimated time of arrival and/or estimated time en route (based on current location and possibly traffic patterns and travel time) of those attendees not yet at the event/meeting. 
     Other interfaces may include location-based fields and location-security fields in a meeting invitation. Such fields may also be incorporated into an acceptance notice or input screen. For instance, example location security fields might include check boxes on a meeting acceptance page with the check boxes specifying whether to reveal location information to other meeting attendees who would not otherwise have access to a user&#39;s specific location. Also, the fields might specify a time range for disclosing the location information such as thirty minutes before the start of the meeting until thirty minutes after a meeting. 
     These location-based and location-security fields related to a meeting could be global parameters in a meeting or scheduling system (e.g., Microsoft Outlook), or they could be per meeting parameters that are changed for various types of meetings that a user books to his/her calendar. The default value for the security settings could be configured as a global value for the meeting or scheduling system with individualized control to change the fields/settings to specific values on each meeting. For some meetings, a user might want to disclose location information and not disclose the location information for other meetings. These types of settings could be configured as a global default that gets applies to every meeting unless the user specifically changes the settings in a configuration for a particular meeting. 
       FIG. 12  is an exemplary screenshot representation of a graphical user interface to the meeting program. In the example shown in  FIG. 12 , an interface showing a meeting status is provided. The interface includes a location status column  1110  and a tracking tab  1105 . The tracking tab  1105  may be used by an organizer of the meeting request to determine who has responded to the meeting request with acceptances or declinations. The location column  1110  is a field (or set of fields) to show the status of meeting attendees and their likelihood of making the scheduled meeting. 
     In some embodiments, the location field  1110  for the meeting organizer also could include a location information status when a meeting attendee&#39;s location information was not available based on: security limits, location system unavailability, or the attendee totally powering down his wireless device, perhaps by removing the battery. For instance, the field could be set to “Loc Info Not Available” when a meeting attendee&#39;s location information was not available. Also, the field could be set to “Loc Info Will Be Available in 18 Minutes” for an attendee that allowed his or her location to be disclosed thirty minutes before a meeting that is scheduled to begin in 30+18=48 minutes. The thirty minute lead time for disclosing location information by relaxing security restrictions is a non-limiting arbitrary number, which could be configured by the attendee when he or she accepts the meeting, or at some other time before the meeting begins. 
     Accordingly, other interfaces to the meeting system may also include fields for the location system. For example, one set of fields may allow meeting notice recipients to change the security settings (as part of the process of acceptance of a meeting request) for disclosing their location information to the meeting holder and/or other meeting attendees. Another set of fields would provide the meeting organizer (and perhaps other attendees and other proxy individuals with the proper security permissions) information to determine the aggregated location status of several scheduled meeting attendees as the meeting approaches in time and actually occurs. 
     Likewise, fields in displays to the meeting organizer or other person with appropriate access could further provide estimated time of arrival (ETA) and/or estimated time en route as well as summarized information relative to the meeting start time such as displaying “Person X will be (or is expected to be) 10 minutes late for the start of the meeting.” These estimates can be based upon historical and/or actual road traffic conditions and patterns as well as information on transit system and transit vehicle (such as airplanes, buses, trains, and boats/ships) delays and/or cancellations. 
       FIG. 13  provides an exemplary graphical user interface of the output for the monitoring system for monitoring potential attendees selected from  FIG. 11 . As can be seen, the screen display provides a map of the area surrounding the meeting location. The map is scaled such that each of the three individuals to be monitored appears on the same map. In this map, as can be seen, Jim (“3”) is located at the meeting place, Jeff (“2”) is located on the road leading to the meeting place, and Scott (“4”) is located at Billy&#39;s Bar. The system may also provide the speed of movement of the wireless device  114  carried by an individual and the direction of travel. Depending upon the amount of information stored in the location database  140 , the system could also provide a history of an individual&#39;s movement throughout the course of the day. 
     Options may be provided to re-scale the map or to display additional information in greater detail. In this case, the system may indicate that Scott has stayed at Billy&#39;s Bar for at least two hours, since noon. The system also provides an estimation that Scott is not on track to make the scheduled meeting. 
     According to exemplary embodiments, the monitoring system of the present disclosure can be configured with added features depending upon the specific application for which the system will be used. Embodiments can be used to monitor individuals who carry any of several different types of wireless communications products, such as the devices  114 . As one example, the monitoring system of the present invention can be used to monitor the location of an individual carrying an interactive pager. Likewise, the system can also be used for monitoring the location of an individual who carries a personal digital assistant that is configured for wireless communication on the wireless network  110 . For the purposes of this disclosure, the interactive pager or personal digital assistant transmits control signals in the same manner as cellular telephones, and can therefore be used as monitoring equipment in the same manner. As yet another feature of exemplary embodiments, a user who accesses the monitoring system through a website on the Internet may wish to leave a text message for an individual who is being monitored. For example, a supervisor may wish to leave a message for an employee. During the operation of the monitoring system, the graphical user interface can include a feature to leave a text message for a monitored individual. The entered text is then communicated from an http server  195  to the wireless network  110 , and on through a control channel to the wireless device  114  at the location in which it is registered. 
     Instead of just providing location information to a central or third party system, a third party monitoring system could provide location information about other remote co-workers or employees to remote devices  114 . For example, an attendee to a meeting can be notified of how many other attendees have arrived at the meeting location. As another example, a police officer may be notified of how close the next back-up patrol car is located. A service technician may be informed of the location of another service truck that might have a needed tool to complete a service call. 
     In general, a person may have a default level of privacy for various groups that allows each of these various groups (such as, but not limited to family, friends, co-workers, acquaintances, strangers) different levels of information about a person&#39;s location. However, from time to time a user may wish to modify the location security preferences to provide more or less accurate information to various groups of recipients. For example, a user may decide to allow co-workers to have more accurate information about a user&#39;s location when a user is scheduled to attend a meeting at work. A person may choose to allow the co-workers to have more accurate information (than the normal/default level of accuracy provided to co-workers) from a time beginning thirty minutes before a scheduled meeting until thirty minutes after a scheduled meeting. Then co-workers will have more information about whether to hold up starting the meeting for a minute or two based on a person&#39;s pending arrival in the building as determined by the accurate information about the person&#39;s location. 
     Furthermore, the relaxation of security/privacy rules to allow more accurate location information to be conveyed to co-workers can be based upon acceptance of a meeting invitation in a scheduling or appointment system such as, but not limited to, Microsoft Outlook™. 
     For users of wireless network devices  114 , concerns over privacy are well founded, especially when considering the increasing convergence of wireless communication networks  110  with global computer networks  112 . Wireless networks  110  are now routinely in communication with the global computer network  112 , providing network users with expanded services such as Internet access through their wireless devices  114 . Through this same link, wireless network providers can provide third parties, such as advertising web sites, with the identity and location information that the network provider is (or will be) required to monitor. Consequently, third parties are able to identify a network user and track that user&#39;s every movement. Accordingly, a user may desire to limit the scope of information available to a third party regarding the user&#39;s current location. 
     In one embodiment, geographical location information for the wireless devices  114  to be monitored is calculated by the location server  120  and output to the location database  140 . The location database  140  maintains the geographical coordinates or a geographical description for each wireless device  114  to be monitored and an account number identifying the wireless device  114 . In alternative embodiments, the location database  140  may additionally store information such as the speed of movement of the wireless device  114  and the direction of its movement, with the speed and direction together implying the velocity vector. 
     In one embodiment, the location database  140  is connected to http server  195  to provide information to the Internet. The information provided in the location database  140  may be combined with information provided by mapping software (or hardware) and information retrieval directories, and the output is displayed on a website as a graphical interface (such as that shown in  FIG. 12 ). The website can be accessed by authorized users through various media, including the personal computer  198  or a wireless handheld device, such as the device  114 . 
     Using various opt-in or opt-out default rules plus user-defined or service-provider-defined rules, the user of the remote device  114 , such as a cell phone, pager, PDA, MP3 player, or GPS receiver, could control whether location information is provided to others and at what level of geographic accuracy. 
     The rules on providing location information could vary based upon one or more of the following as well as possibly other additional factors: who is receiving the information about the location of the user (e.g., family, friends/buddy list, stranger); the location of the user (e.g., restroom, at home, in the office); the defined characteristics of locations (such as fuzzy zones in bathrooms); and time of day, work day, and/or holiday scheduling (e.g., location information provided to co-workers 9 AM-5 M-F versus provided to family 24 hours/day×7 days/week). 
     For instance, a user may elect to give his family exact location information, while less well-known acquaintances may only be entitled to receive location information about the user being within a particular city. Also, location information could be blocked by the user, in some embodiments. Parents have a blocking override option with the interface to find out the location of their children&#39;s cell phones on which the children have tried to block location, in some embodiments. 
     In addition, location information may include purposely fuzzy or inaccurate zones in which the location information transmitted into the location database  140  is not exact. For instance, under a particular positioning system technology, the location information may be accurate to within three feet. However, a person going into an office building restroom may not want to divulge his location that accurately. Upon passing into a location zone defined by a threshold boundary of a bathroom door, the reported location may just specify the bathroom, but not the specific location within the bathroom. The remote devices  114  (or the network triangulation devices) could automatically report less accurate information about location whenever the user crosses into one of these “fuzzy” or less-accurate geographical zones. 
     Accordingly, location information of a user may be purposely provided in a less accurate manner for privacy reasons. However, the accuracy of the mobile location information can be controlled at a finer granularity than just an on/off decision of allowing or not allowing accurate location information to be delivered to a specific group of users with authorized access. Instead, an employee may want to receive an incoming phone call and let his boss know that the employee is in the general vicinity of the office, but the employee may not want to let his boss know that the employee is in the restroom or even a specific stall in the restroom (if the location information is capable of providing that level of accuracy). Instead, users of location services may want certain geographical zones of privacy in which the location information is purposely provided to other people communicating with the users in a way that has less accuracy than the location system is capable of providing. Furthermore, users may wish to provide “dummy” information about their location for security reasons and other purposes. For example, a user may want to provide dummy information about being “in the office”, when the user is really out on a sales call at a business. Also, someone who is out-of-town on vacation may not want to disclose that he is out-of-town to every person with whom he communicates while on vacation. For business reasons and/or security reasons (related to the current occupancy of a person&#39;s residential home), a person may want to provide location information that indicates that the person is in town as opposed to being out-of-town. 
     In one embodiment, a pseudo-location service for use in wireless networks that track the locations and identities of network users provides pseudo-location information for a network user. The pseudo-location service provides a wireless network user with the ability to prevent the current location of her wireless handheld device  114  from being disclosed to parties other than the wireless network provider and possibly emergency personnel, such as a 911 response unit. The present disclosure contemplates future enhanced digital cellular networks, in which network users will use digital cellular handheld devices to access data from the global computer network  112 , and in which digital cellular network providers will track the identity and location of each network user. 
     Referring to  FIG. 13 , in an exemplary embodiment, the wireless device  114  include a user interface  1210  and a pseudo-location processor  1230 , and the wireless network  110  includes a pseudo-location network processor  1240  for providing pseudo-location service. User interface  1210  and the pseudo-location processor  1230  are provisioned in the wireless handheld device  114  and are in communication with each other. The pseudo-location network processor  1240  is provisioned in the wireless network  110 . In the context of an entire network, wireless network  110  is in communication with the plurality of handheld devices  114 , and the pseudo-location network processor  1240  would be in communication with a plurality of user interfaces. 
     The device-based location system  115  and the network-based location system  111  provide the location of the wireless handheld device  114 . Depending on the desired degree of accuracy, one or both of the location systems  111 ,  115  can be used to determine a device&#39;s location. As previously discussed, one embodiment of the device-based location system  115  is the GPS receiver  116  provisioned in the wireless handheld device  114 . One embodiment of the network-based location system  111  is a WAP location service. 
     According to exemplary embodiments, the user interface  1210  is an application that operates on the wireless handheld device  114  and enables communication between the user of the device  114  and the pseudo-location processors  1230  and  1240 . The user interface  1210  may prompt the user of handheld device  114  to enter commands initiating or suspending pseudo-location activities. Examples of suitable user interfaces include menu selections, key sequences such as “*87”, and graphical user interfaces (provided that the hardware and memory support such applications). In accordance with the user&#39;s command, the user interface  1210  alters the way in which the pseudo-location processors  1230  and  1240  operate. The user interface  1210  may recognize from where location information originates, and communicates with the appropriate pseudo-location processor  1230 ,  1240 . That is, if the device-based location system  115  provides the location information, the user interface  1210  directs either of the pseudo-location processors  1230  or  1240  to replace the location information with a pseudo-location. Correspondingly, if the network-based location system  111  provides the location information, the user interface  1210  directs the pseudo-location network processor  1240  to replace the location information with a pseudo-location. 
     The pseudo-location processor  1230  and the pseudo-location network processor  1240  are applications that receive and execute commands from the user interface  1210 , according to exemplary embodiments. Primarily, the pseudo-location processors  1230  and  1240  replace location information with pseudo-location information. For example, the processors  1230  and  1240  can disable a location system and substitute pseudo-location information or can receive location information and substitute pseudo-location information. Substituting pseudo-location information could comprise substituting location information that is near the current location or at a set distance from the current location. For example, pseudo-location information may be set to be five miles to the west of the current location. Alternatively, a predefined location may have been previously designated as a substitute for a current location. For instance, a user may designate that a location corresponding to the entrance of the user&#39;s work center is to be used as a pseudo-location for the location corresponding to the work center&#39;s restroom facilities. 
     To substitute pseudo-location information, the pseudo-location processor  1230  may either disable the device-based location system  115  or substitute pseudo-location information for the location information that system  115  provides. The pseudo-location network processor  1240  may remove location information from transmissions before they are forwarded outside of the wireless network  110 . If the location information originates from the device-based location system  115 , the pseudo-location processor  1230  removes the location information from the transmission and substitutes pseudo-location information, according to exemplary embodiments. If the location information originates from the network-based location system  111 , the pseudo-location network processor  1240  may either disable the network-based location system  111  or substitute pseudo-location information for the location information received from the network-based location system  111 . 
     As one of ordinary skill in the art would understand, the pseudo-location network processor  1240  could be a separate component of the wireless network  110 , or could be a part of a proxy server that acts as an intermediary between a plurality of handheld devices and the computer network  112  to provide routing selection (i.e., what transport bearer is to be used), access control, addressing, protocol conversion (i.e., WML text to WML binary), caching, and transport interface between wireless and wired networks (e.g., WAP stack to traditional IP stack, HTTP/TCP/IP). The proxy server may be associated with or part of a gateway server that separates the wireless network  110  from the computer network  112 , such as the Internet. The proxy server could also be associated with a firewall server that protects the wireless network  110  from intrusion via the computer network  112 . 
     Based on the system architecture shown in  FIG. 14 , exemplary embodiments provide pseudo-location services by several exemplary methods, depending on which location system  111 ,  115  provides the location information: 1) If both the device-based location system  115  and the network-based location system  111  provide location information, the user interface  1210  directs the pseudo-location network processor  1240  not to forward location information; 2) If only the device-based location system  111  provides location information, the user interface  1210  directs either the pseudo-location processor  1230  or the pseudo-location network processor  1240  not to forward the location information; and 3) If only the network-based location system  111  provides the location information, the user interface  1210  directs the pseudo-location network processor  1240  not to forward the location information. 
     In one embodiment, the user interface  1210  can enable the user to establish a user profile, to be stored in the pseudo-location processor  1230  or the pseudo-location network processor  1240 , as appropriate for the active location system  111 ,  115 . The profile specifies conditions under which location information is blocked for a user. These conditions can include such parameters as the recipient of the transmission, the time of day, and the location of the user (i.e., if the user never wants to be caught in a particular location, she can specify that that location always be substituted with a pseudo-location). The user interface  1210  allows the user to establish, edit, enable, and disable the profile. When the profile is enabled, the pseudo-location processor responsible for replacing the location information (processor  1230  or  1240 ) may evaluate the transmission to see if the transmission meets the profile parameters, and if so, replaces the location information with the appropriate pseudo-location. Thus, for example, if a user has specified that his or her employer is not to receive accurate location information, the pseudo-location processor  1230  or  1240  reads each data transmission to ascertain the recipient, compares the recipient to the names of the user&#39;s employers in the profile, and replaces the location information with pseudo-location information if the recipient&#39;s name matches those names (of the employers) listed in the profile. 
       FIG. 15  illustrates an alternate embodiment of the present disclosure in which a pseudo-location network user interface  1350  is provisioned in wireless network  110 , in communication with the pseudo-location network processor  1340 . The pseudo-location network user interface  1350  provides an alternate means of initiating or suspending pseudo-location services and for altering user profiles. Unlike the user interface  1310 , which operates on device  114 , the pseudo-location network user interface  1350  operates within the wireless network  110 . For example, the pseudo-location network user interface  1350  could be a web-enabled graphical user interface accessible by a network user through the computer network  112 . In this manner, a user would access the web page of the graphical user interface  1350  and change the parameters to affect the desired pseudo-location service. This web accessible interface  1350  would be especially beneficial for users who prefer to establish pseudo-location services for certain recipients only, because such a service would require a considerable amount of detailed input by the user. 
     According to one embodiment, the processors  1330  and  1340  are programmed to override pseudo-location services when necessary. For example, even if the user has chosen to activate a pseudo-location service for all transmissions, the pseudo-location processors  1330  and  1340  automatically reactivate the location service if the user dials 911 so that an emergency response service receives the critical location information. In another embodiment, a wireless network pseudo-location service is provided irrespective of related services. 
     To establish geographic zones, a user may utilize the user interface  1210 ,  1310  of the wireless device  114  or the user interface  1350  of the wireless network  110  to select points or nodes to define the zone. For example,  FIG. 16  illustrates an interface screen which prompts a user to select a current location as a vertex within a geographic zone being established by the user. Therefore, the user may physically walk to a physical location where the user wants to establish a geographic zone and by using the user interface  1210 ,  1310  and selecting an OK button or by selecting a graphical OK link on the device display, a user can enter a vertex within a geographic zone. After the user has entered all the desired vertices, then the vertices are connected to establish a perimeter or zone. Accordingly,  FIG. 17  illustrates an interface screen prompting a user to select a Done link to indicate that all the desired vertices have been entered. Alternatively, to establish a geographic zone, the user may input a current location, as identified by the GPS receiver  116  of the wireless device  114  for example, as a center of a circular perimeter or zone.  FIG. 18  illustrates an interface screen prompting a user to input such a point. After the center is specified, then the user can input a radius for the circular perimeter or zone, as illustrated in  FIG. 19 . Accordingly, using the above approaches, a user can define a geographic zone. In accordance with one embodiment, the geographic zone is used to map a current location that falls within the zone to a pseudo-location. Similarly to the above approaches, a user may also specify the pseudo-location. For example, a user may physically move to a location which will be identified by the GPS receiver  116  of the wireless device  114  of the user. As shown in  FIG. 20 , a user interface, such as the user interface  1210 ,  1310 , of the device  114  may enable a user to select the location as a pseudo-location. 
     Referring now to  FIG. 21 , one embodiment of the present disclosure is figuratively represented. As shown, vertices  1910  inputted by a user help define a geographic zone  1920 . Therefore, when the wireless device  114  enters a location represented by the zone  1920 , the location system  111 ,  115  may report the location, as reflected by the arrow  1930 , as a pseudo-location to the third party server  150 . In the example, the correct location of the wireless device  114  is 55 degrees north and 33 degrees east. However, in accordance with exemplary embodiments, a pseudo-location is reported corresponding to 40 degrees north and 74 degrees west. 
     In one embodiment, user interface screens provided on the wireless device  114  may allow a user to select individuals from the user&#39;s “buddy” or contact list or address book as recipients for pseudo-location information, as represented in  FIG. 22 . 
       FIG. 23  is a flowchart describing one embodiment of a method for instituting privacy control of location information. One embodiment of such a method includes defining ( 2110 ) a geographic area for which pseudo-location information is to be provided (via wireless device  114 , location server  120 , and/or third party server  150 ). The method further comprises defining ( 2120 ) parameters on which individuals or entities are to receive the pseudo-location information (via wireless device  114 , location server  120 , and/or third party server  150 ). Accordingly, if a current location of a user is received ( 2130 ) that falls into the geographic area, then pseudo-location information is reported ( 2140 ) to individual(s) or entities selected for receiving the pseudo-location information (via wireless device  114 , location server  120 , and/or third party server  150 ). Otherwise, if a current location of a user is received ( 2150 ) that is outside of the defined geographic area, then the correct location information is reported ( 2160 ) to individual(s) or entities not selected for receiving the pseudo-location information (via wireless device  114 , location server  120 , and/or third party server  150 ). 
     In some embodiments, whether creating a geographic zone for providing pseudo-location information or a zone or a geographic zone for adjusting device features, a user interface, such as the user interface  1210 ,  1310 , may be provided on the wireless device  114  that allows the user to select popular geographic zones in the user&#39;s area or an area inputted by a user (via a zip code, for example). For example,  FIG. 24  shows a screen interface allowing a user to select to implement a geographic zone according to establishments in the user&#39;s area, such as baseball park Turner Field, sports venue Philips Arena, and/or music and show venue Fox Theater. 
     While the system operation described herein and illustrated in the diagrams and flowcharts contains many specific details, these specific details should not be construed as limitations on the scope of the disclosure, but rather as an example of embodiments thereof. As would be apparent to one of ordinary skill in the art, many other variations on the system operation are possible, including differently grouped and ordered method steps. Accordingly, the scope of the disclosure should be determined not by the embodiments illustrated, but by the appended claims and their equivalents. 
     In the future, due to the mandate to establish E911 services, the wireless network  110  will be monitoring the locations and identities of the wireless handheld devices  114  for emergency purposes. As a result, network service providers will presumably attempt to capitalize on the mandated service by providing the locations and identities to web sites. Among other possible applications, web sites will use the valuable information to direct targeted advertisements to the handheld devices  114 . For example, web sites may wish to locate wireless handheld devices  114  near a retail store, and send those devices an advertisement encouraging the network users to visit the store. 
       FIG. 25  is an exemplary block diagram showing circuit blocks constituting one embodiment, among others, of the wireless communication device  114  and particularly, a cell phone. The cell phone  114  includes a display screen (or “display”)  2328 , a keypad or keyboard  2330 , a speaker  2332  and a microphone  2334 . The keys or “buttons” on the keypad  2330  may be provided as, for example, push-button keys or computer keyboard-type keys or membrane keys or any other suitable design configuration. The choice of the type of keys on the keypad  2330  may thus depend on design and aesthetic considerations including, for example, the size, the weight and the desired physical contours for the cell phone  114 . The display screen  2328  may display text or graphic messages thereon. For example, when the user browses the Internet  112 , the display screen  2328  may display the content of web pages for the user to look at. In one embodiment, the display screen  2328  may be an LCD (liquid crystal display) display. In alternative embodiments, the display screen may be, for example, a TFT (thin film transistor) active matrix display or a touch-sensitive screen. 
     Additional circuit elements include an audio logic unit  2340 , a display logic unit  2342 , a keypad interface logic unit  2344 , a memory or storage unit  2346 , a web browser module  2348  and a network interface unit (NIU)  2360 . These circuit elements are shown coupled to a processing and control unit (PCU)  2352  that manages and controls various operations performed by these circuit elements, including tracking and monitoring operations in accordance with the present disclosure. The NIU  2360  may include a wireless modem  2362 , an RF (radio frequency) transceiver unit  2364  and an RF antenna unit  2366  so as to enable the web browser module  2348  to transmit and receive digital information over the Internet  110 . 
     The audio logic unit  2340  may be connected to the microphone  2334  and the speaker  2332 . The speaker  2332  may be activated by the audio logic unit  2340  when, for example, the PCU  2352  informs the audio logic unit  2340  that the MS has initiated a telephone conversation. Voice messages may first be received by the PCU  2352  (via the NIU  2360 ) and the PCU  2352  may transmit these signals to the audio logic unit  2340  to be sent to the speaker  2332  for generating audible sound. Alternatively, any digital audio files received by the cell phone  114  (using the NIU  2360 ) over the Internet may first be sent to the web browser module  2348  to retrieve the audio file data therefrom. The browser module  2348  may then send the audio data to the PCU  2352 , which, in turn, forwards the audio data to the audio logic unit  2340  and eventually to the speaker  2332  for audible playback. 
     The user of the cell phone  114  may speak into the microphone  2334  to transmit the user&#39;s voice during, for example, a telephone conversation. The audio logic unit  2340  receives the electrical audio signals from the microphone  2334  and sends them to the PCU  2352 , which, in conjunction with the NIU  2360  transmits the user&#39;s voice to the wireless network  110 . In one embodiment, the PCU  2352  may generate digital audio files from the analog audio signals received from the microphone  2334 . The browser module  2348  may send TCP/IP messages over the Internet containing these digital audio files so as to allow the user to carry out voice communication over the Internet. The digital audio file formats may include file extensions such as, for example, “.WAV” (wave file), “.AIFF” (Audio Interchange File Format), “.AU” (audio file), etc. 
     The display logic unit  2342  monitors and manages display functionality for the cell phone  114 . The PCU  2352  may generate proper commands and signals for the display logic unit  2342 , which, in turn, may control the display of visual information on the display screen  2328 . The display screen  2328  may display various information such as, for example, an e-mail message received over the Internet, any data entered via the keypad  2330  or an intimation of which action is being performed by the cell phone  114 . For example, a message such as “ACCESSING THE INTERNET” may also be sent to the display logic unit  2342  (to be displayed on the display screen  2328 ) by the PCU  2352  once the PCU  2352  receives an indication from the web browser module  2348  that Internet access is in progress. Other messages may also be conveniently displayed on the screen  2328 . For example, as soon as the user presses a key on the keypad  2330 , the corresponding digit, symbol or command may be displayed on the display screen  2328  by the display logic unit  2342 . 
     The keypad interface logic  2344  is coupled to the keyboard  2330  and receives signals sent from the keyboard  2330  when the user presses one or more keys thereon. The user may enter data such as, for example, a telephone number, a web address, an e-mail message, etc., using various keys on the keypad  2330 . The web browser module  2348  may need a portion of such data to determine how to access content over the Internet. Furthermore, the user may also prefer to enter personal information about the user, e.g., the user&#39;s name, the address of the user&#39;s contact location, any known medical condition, etc., using keys on the keypad  2330  and store that personal information in the memory unit  2346 . 
     The keypad interface  2344  transmits the signals received from the keyboard  2330  to the PCU  2352  for further processing. The PCU  2352  decodes the received signals and accordingly instructs the appropriate circuit elements for necessary action. For example, when the user enters the user&#39;s personal information, the keypad interface logic  2344  may send all the data to the PCU  2352 , which may instruct the memory unit  2346  to store the received data therein. The PCU  2352  may store the user&#39;s personal identification information in the memory  2346  using one of a number of digital text formats, e.g., HTML (Hyper Text Markup Language) format, ASCII (American Standard Code for Information Interchange) format, XML (Extensible Markup Language) text file format developed by W3C (World Wide Web Consortium), etc. 
     In one embodiment, the cell phone  114  may include a text-to-speech (TTS) converter (not shown). The TTS conversion functionality may be implemented with appropriate software residing in the PCU  2352 . The TTS converter may work with an SGML (Standard Generalized Markup Language) format-based TTS markup language. The SGML format may be based on the ASCII text format. An example of an SGML-based TTS markup language includes the STML (Spoken Text Markup Language) developed by Lucent Technologies of Murray Hill, N.J., U.S.A. In that embodiment, the cell phone  114  may be configured to receive an e-mail or other messages in the SGML format over the Internet. The TTS converter may convert the received text file (in the SGML format) into an STML file that can be audibly played back by the audio logic unit  2340 . The user of the cell phone  114  can thus hear, in a synthesized voice, the content of the message sent in a digital text format. 
     The memory or storage unit  2346  provides memory for storage of data, such as the user&#39;s personal information as discussed hereinbefore. The data stored locally in the memory unit  2346  may be text, audio or video data and may include a number of digital file formats as described hereinbefore. For example, data that may be sent over the Internet may be in the HTML or the WML (Wireless Markup Language) formats. The memory unit  2346  may be located inside the cell phone  10  or, alternatively, may be supplied as a memory cartridge (not shown) that may be attached to the cell phone  114  at an appropriate adapter slot (not shown) provided on the housing for the cell phone  114 . 
     The memory unit  2346  may include volatile and/or non-volatile memory, such as RAM (Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory) or similar memory units. A volatile memory may lose the data stored therein if the power applied thereto is removed. The personal information about the user (as an audio file or as a text file) may be stored in the non-volatile portion of the memory  2346 . On the other hand, the content of a web page accessed through the web browser  2348  may be stored in the volatile portion (or temporary storage) of the memory  2346 . 
     The web browser module  2348  may include software code or routines which, when executed by the PCU  2352 , perform web browser functions upon execution. In one embodiment, the web browser module  2348  may be implemented using a combination of software and hardware elements. The web browser software may include, for example, an HTML browser or a WAP (Wireless Application Protocol) browser because of the small size and portable nature of the cell phone  114  and because of the smaller display  2328  and limited memory space (in the memory unit  2346 ) available for the cell phone  114 . The HTML browser may “read” information received or stored in the HTML format, whereas the WAP browser may be able to “read” information having WAP content (e.g., information in the WML (Wireless Mark-up Language) format). In the embodiment illustrated in  FIG. 25 , the web browser module  2348  includes a WAP browser that wirelessly connects the cell phone  114  to the Internet. 
     The web browser  2348  may be activated using one or more keys on the keypad  2330  and may be used for surfing the world wide web portion of the Internet. The web browser module  2348  interacts with the PCU  2352  to execute necessary software routines for Internet access. The software routines, upon execution, activate the wireless modem  2362  in the NIU  2360  to accomplish dialed Internet access via the wireless network  110 . In one embodiment, the web browser module  2348  (including its hardware and/or software elements) may be a part of the PCU  2352  and the PCU  2352  may directly perform web browsing or information delivery over the Internet. 
     Inclusion of the web browser  2348  within the cell phone  114  may result in a standardized information interface for the cell phone  114  because it dispenses with the need to have a proprietary format for information transmission, storage and display. The messages to and from the cell phone  114  need not have to be in a proprietary format, but, instead, may be in a generally available text format, e.g., the HTML format or the WML format. This allows for ease of Internet communication with the cell phone  114  because of the use of TCP/IP data packets over the Internet for information exchange. 
     As noted hereinbefore, the web browser module  2348  includes the WAP browser software represented as a WAP stack  2349 . The WAP architecture provides a scaleable and extensible environment for application development for mobile communication devices such as, for example, the cell phone  114 . The WAP protocol is designed in the form of a layered architecture wherein each of the layers is accessible by the layers above, as well as by other services and applications running on the WAP platform. The WAP stack  2349  has the application layer (not shown) at its top, which is successively followed by the session layer (not shown), the transaction layer (not shown), the security layer (not shown) and the transport layer, which is referred to as a WDP (Wireless Datagram Protocol) and Adaptation layer  2350  in  FIG. 25  (and interchangeably referred to hereinbelow as “the WDP layer” or “the adaptation layer” for the sake of clarity). 
     The WDP layer  2350  is the lowest layer in the WAP stack that is in direct contact with a physical network carrying the WAP data. The WDP layer  2350  operates above the data-capable bearer services supported by various physical networks. A bearer service is a data transport mechanism that carries the WDP protocols between two devices. Some non-limiting examples of bearer services include, for example, SMS (Short Message Service), circuit switched data and packetized data. Non-limiting examples of some physical networks that carry the bearer data include a GSM (Global System for Mobile Communications) or another TDMA-based (Time Division Multiple Access) wireless network, a wireline network (e.g., the PSTN or the Internet), etc. The WDP protocol can be mapped onto different bearers, with different characteristics. The adaptation layer  2350  is the layer of the WDP protocol that maps the WDP protocol functions directly onto a specific bearer. Thus, operationally, the WDP layer  2350  provides convergence between a given bearer service and the rest of the WAP stack  2349 . The content of the adaptation layer  2350  may be different for each bearer depending on, for example, specific capabilities and characteristics of that bearer service. 
     In the embodiment of  FIG. 25 , the WDP and adaptation layer  2350  in the WAP stack  2349  may map WDP protocol functions onto the packetized data (i.e., the bearer service) supported by the wireless network  110  to facilitate communication between the web browser module  2348  and the remote source of data. The WDP layer  2350  may thus adapt the datagrams transmitted and received thereby to conform to the data transmission protocol specified by the physical data carrier network, i.e., the wireless network  110 . As noted hereinbefore, the WAP browser in the web browser module  2348  may communicate with the remotely-located source of data using a WAP-supported data format, e.g., the WML format. For bearer services supporting IP (Internet Protocol), the WDP protocol may be UDP (User Datagram Protocol) that provides port-based addressing (e.g., source port, destination port, etc.) which may be combined with the segmentation and reassembly features of IP-based routing to implement a connectionless datagram service between two devices. 
     The PCU  2352  manages and controls various operations performed by different circuit elements connected thereto. The PCU  2352  functions as a centralized location to send and receive various commands and information. For example, the PCU  2352  may receive a signal from the keypad interface logic  2344  when the MS wishes to access the Internet. In response, the PCU  2352  may execute the web browser software in the browser module  2348  to initiate an Internet connection. The PCU  2352  may receive content of a web page or an e-mail over the Internet and may, in turn, instruct the display logic  2342  to display the received web page or e-mail on the display screen  2328 . Alternatively, the PCU  2352  may instruct the TTS converter (not shown) to audibly “play” a message text using the audio logic unit  2340  and the speaker  2332  as described hereinbefore. During web browsing, the PCU  2352  may also execute audio and video data files received from the Internet using the web browser module  2348  and send appropriate audio and video signals to the audio logic unit  2340  and the display logic unit  2342  respectively. 
     The cell phone  114  may include some additional optional circuit elements such as, for example, a user location identifier  2354  including a GPS (Global Positioning System) receiver  116  and a GPS receiver antenna  2358 . The GPS receiver antenna  2358  may be provided on the cell phone  114  to continuously receive location signals from geo-stationary satellites and transfer those signals to the GPS receiver  116  to identify the current location of the cell phone  114  and, hence, the location of the user carrying the cell phone  114 . Instead of a built-in location identifier  2354 , the cell phone  114  may be provided with a port (not shown) to receive an external location identifier (with or without the receiver antenna  2358 ) that may be attached to the port when needed. The GPS location identifier  2354  may perform better in an outdoor environment, e.g., when the user is on the road. In one embodiment, the user location identifier  2354  may supply the PCU  2352  with the requisite location information and the PCU  2352 , with the help of the web browser module  2348  and the network interface unit  2360 , may send the user location information over the Internet  18 . Alternatively, the PCU  2352  may send the user&#39;s location information to the cellular service provider via the wireless network  110 . As stated, the cell phone  114  may also include optional circuit elements such as a RFID reader (not shown), user database (not shown), etc. 
     The network interface unit  2360  provides an electrical interface for signals travelling between various circuit elements inside the cell phone  114  and a wireless carrier network, e.g., the wireless network  110  in  FIG. 1 . Data communication signals (including the TCP/IP messages) transmitted and/or received by the web browser module  2348  may pass through the NIU  2360  prior to reaching their appropriate destinations. The NIU  2360  may provide signal amplification in, for example, a noisy signal environment. 
     The network interface unit  2360  employs wireless devices to transfer data and information from the cell phone  114  over the Internet  112 . An antenna, e.g., an RF (radio frequency) antenna  2366 , may be provided on the cell phone  114  to allow wireless data communication. Data communication may be accomplished via a wireless modem  2362  using the wireless network  110 . When the wireless network  110  is a cellular network (e.g., a TDMA-based wireless network or a CDMA-based wireless network), the wireless modem  2362  may be capable of data transfer using the message format supported by the given cellular network. 
     The web browser module  2348  in the cell phone  114  may be configured to transfer data over the wireless network  110  and, hence, the web browser module  2348  may be connected to the NIU  2360 . The web browser module  2348  in  FIG. 24  includes a WAP browser. However, a web browser module  2348  with an HTML browser may be similarly configured to perform data transmission and reception operations using wireless devices. The cell phone  114  may also include a web browser module  2348  with browser software that supports a content format that is different from HTML or WML such as, for example, the JavaScript scripting language. A cell phone may be conveniently designed to include such a web browser module for data communication. 
     The RF transceiver unit  2364  sends RF signals to the RF antenna  2366  for transmission to the wireless network  110  and receives RF signals from the RF antenna  2366  and forwards them to the wireless modem  2362  for further processing. The RF antenna  2366  provides the necessary signaling interface between the wireless network  110  and the web browser module  2348  that needs to access the wireless network  110 . 
     The wireless modem  2362  may perform necessary data encoding for the data received from the WAP browser in the web browser module  2348  to prepare the data (e.g., a query message) to be sent to the wireless network  110  and eventually over the Internet  112 . A corresponding decoding may be performed by the wireless modem  2362  upon receipt of data from the RF transceiver unit  2364  prior to sending the decoded data to the WAP browser (in the web browser module  2348 ) for further processing. The RF transceiver unit  2364  modulates data received from the wireless modem  2362  to be transmitted over an RF transmission channel linking the cell phone  114  with the wireless network  110 . This modulated data is then wirelessly transmitted to the wireless network  110  (and, hence, to the Internet  112 ) by the RF antenna unit  2366 . Upon reception of any data or information from the wireless network  110  (e.g., an e-mail message received over the Internet), the RF antenna unit  2366  forwards the RF-modulated data to the RF transceiver unit  2364 , which demodulates the data and sends it to the wireless modem  2362  for further processing and transfer to the WAP browser in the web browser module  2348 .
