     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to communications systems, methods and devices. More particularly, exemplary embodiments of the invention concern systems and methods directed to providing location-based, context-aware content and displaying it within a ticker on a user device. 
     2. Related Technology 
     The popularity of the Internet has given rise to a plethora of information services as consumers have become accustomed to accessing timely, personalized news and information. As a result, demand for these types of content services continues to grow. Scrolling information displays, referred to herein as “tickers,” are one type of content distribution mechanism that can give a viewer a quick, high-level update, and they have become commonplace on the television news and on sports channels, providing viewers with “at-a-glance” headlines, breaking news, weather reports, sports scores and other updates. 
     One early example of a scrolling information display or “ticker” on a personal computer (PC) system was that provided by PointCast. Through the PointCast service, PC users could subscribe to news and information channels of interest and receive periodic updates on their computer displays, often in the form of a scrolling information display at the bottom of the user&#39;s display screen—commonly known as a ticker. An even earlier example of the use of tickers in conjunction with a PC was the ticker provided by gaming company Catapult Entertainment, Inc. The Catapult ticker, in addition to providing information to users of the gaming system about news and current events and gaming-related information such as upcoming tournaments, high scores, and new software releases, was also interactive through the use of the computer mouse. Rather than being limited to the information in the ticker, the user could click on an item in the ticker having a Universal Resource Identifier (URI) associated with it, which would then cause a web page to be displayed with additional information about that item. More recently, through the use of messaging systems with near-universal reach such as the Short Messaging System (SMS), mobile workers can now receive up-to-the-minute business, financial and customer information on their mobile devices from various news and entertainment content providers and from many other information sources, including corporate portals and customer relationship management applications. Furthermore, tickers are beginning to appear as a method for dynamic information display on mobile communication devices, such as cellular telephones, personal digital assistants (PDAs), and “smart” phones. 
     While the value of receiving personalized, timely information in a condensed, quickly-read format such as a ticker is indisputable, the information tickers known in the art could be significantly improved. The continued, rapid growth of mobile communication device use is a reflection of the mobile society in which we live, and increasingly we rely on these devices for news and other information in addition to staying in touch with co-workers, friends and family. Furthermore, the location of a mobile communication device having a connection to a network can be easily determined through signal triangulation methods or other methods, and the proliferation of GPS enabled devices fueled by government regulatory requirements to improve public safety means that the location of any cell phone or other mobile communication device can be established. Smaller devices such as wristwatches that can receive information updates promise to make it even more convenient to always carry a mobile communication device, and as applications for these devices such as messaging, calendars and appointment reminders, news alerts, and traffic reports become more popular, the mobile communication device is becoming a more essential requirement for users to guide them through the day. As users of these devices move around from home to work, in and out of conference rooms and buildings, between terminals in an airport, from neighborhood to neighborhood, city to city, and between states and countries, they could benefit significantly from an information service that takes into account their geographical location and information preferences and then provides at-a-glance updates to the user&#39;s device that are meaningful and useful to the user in their current location. However, existing ticker services are not capable of responding to the geographic location of the user or providing information that is tailored to the current location of the user. 
     BRIEF SUMMARY OF AN EXEMPLARY EMBODIMENT OF THE INVENTION 
     In general, exemplary embodiments of the invention concern systems and methods for providing location-based, context-aware content to communication devices including mobile communication devices and “immobile” or stationary personal computers, and displaying the location-based content within a ticker on the display of the communication device. While the invention is applicable to immobile or “wired” communication devices including computer systems, landline telephones, televisions, and set top boxes, its application is particularly well-suited to mobile wireless communication devices (referred to hereinafter as “mobile communication device(s)” or “mobile device(s)”) such as laptop and notebook computers, cellular telephones, PDAs, and any other mobile communication device having a display device and enabled to wirelessly receive data. 
     More specifically, embodiments of the invention provide for recognizing the geographical location of a communication device by either receiving location information from the device or from the network, or by receiving profile information input by a user of a communication device as to the location of the device. The device location is then correlated with either or both of user preferences and location-based content pertaining to those preferences. Corresponding promotions, local news, local event information and other location-based content is then transmitted to a data store on the device by a network server, or it is selectively retrieved from a data store on the device in which location-based content that has already been transmitted from external servers is stored pending display on the device. In accordance with a scheduling system and certain rules and preferences, the data received on the device is scheduled for display and then displayed within the ticker on the device at the appropriate time using specified formats and presentation attributes. The methods of the invention are proactive in that location-aware content is pushed to the device and/or displayed within the ticker when the user enters or nears a specified location without the need for the user to actively request it. 
     In the exemplary embodiment, a cellular telephone user subscribes to a location-based ticker service of the invention and indicates preferences for categories of content by inputting the preference via a user interface element on the cell phone. In this case, the user could specify, for example, a preference for Peet&#39;s coffee and indicate a desire to be notified each time a Peet&#39;s coffee store is nearby. The preference is then stored for future reference by the system. As the user changes location throughout the day, the cell phone reports its geographical location or the cell phone location is otherwise communicated periodically to a location-based ticker server of the location-based ticker service, and from time to time the ticker on the user&#39;s cell phone receives content updates, including location-aware content, which is then displayed on the ticker to the user. Alternatively, the location-based ticker server can send a list of Peet&#39;s coffee shop locations along with a message for display within the ticker, and store it on the cell phone. Display rules may be received in metadata associated with the content and stored on the cell phone; these rules are then considered by the scheduling system as it determines when the message from Peet&#39;s should be displayed in the ticker. For example, based on the user&#39;s proximity to a Peet&#39;s location, a message could scroll within the ticker that says “Peet&#39;s coffee  2  blocks west”. Determining a mobile device&#39;s location is well understood in the art and can be done through a number of means including GPS, assisted GPS, or RF triangulation. The ticker scheduling system (described in more detail herein) uses the device location and the information about the location of Peet&#39;s coffee stores to determine what information to display on the ticker. In accordance with such “proximity rules” and other rules that may be stored on the cell phone, on the location-based ticker server, or both, location-based content for the general geographical area, such as a city, may be displayed, and as the user changes location, the content displayed within the ticker may become more finely tuned and specific to the user&#39;s current location. 
     Member vendors of the location-based ticker service may register information about their products and services, including advertisements, promotional information and entertainment-related information with the location-based ticker service. In this example, Peet&#39;s Coffee, a member vendor of the location-based ticker service, could register a promotional coupon with the service, which is then transmitted to communication devices located, for instance, in a particular region such as Northern California. The promotional coupon is associated with metadata that includes a proximity rule stating that if a user arrives at a location within a specified distance of a Peet&#39;s retail store, the information is to be displayed on the ticker of the user&#39;s device. In this case, the Peet&#39;s promotional content may be downloaded at any time—such as during an off-peak time for network traffic-regardless of the user&#39;s current location, and stored on the device pending display when the user reaches the location specified in the proximity rule. 
     Alternatively, the Peet&#39;s promotional information may be stored at the ticker server, and then downloaded to the data store on the device in “real-time” or near real-time when the user reaches the specified location. In this case, when the user&#39;s cell phone travels near a Peet&#39;s Coffee location, the location-based ticker server, having determined that there is a match between the user&#39;s preference for Peet&#39;s, the user&#39;s current location, and the location of the nearest Peet&#39;s, transmits data concerning the nearest Peet&#39;s location to the ticker on the user&#39;s device. The member vendor may specify one proximity rule for mobile communication device users, and another proximity rule for stationary or wired communication devices. Furthermore, other characteristics of the user&#39;s device can be taken into account, such as the speed at which it is moving. The speed and direction of motion of the communication device can be determined through GPS offsets or other methods, included in the geographical information about the communication device, and reported to the location-based ticker server or used to select location-based content stored locally on the communication device. A third proximity rule can be specified for devices in motion. For example, if the device is moving faster than fifteen miles per hour, the proximity rules may say that the Peet&#39;s promotional content should display if the device is within three miles of a Peet&#39;s retail location. 
     According to this example, Peet&#39;s has further specified an expiration time after which the coupon should not be transmitted to the communication devices. Similarly, content transmission may also commence based on time, and the time at which content is transmitted to the device may or may not be independent of the device location. In general, the ticker content can be transmitted or displayed at a time or manner specified by a triggering event. Examples of such triggering events include a specified time or location. Upon the occurrence of the triggering event, content that has been designated as being appropriate for the triggering event (e.g., appropriate for the current time or location of the communication device) is displayed on the ticker or transmitted to the communication device. 
     Returning to the present example, in some cases the Peet&#39;s data may be transmitted directly to a mobile communication device without having first been aggregated at the ticker server. For example, if the mobile device encounters a wireless access point of a wireless local area network (WLAN), such as an 802.11 network, the Peet&#39;s data can be transmitted directly to the mobile device. 
     After the location-based content is transmitted to the device using any of the aforementioned methods, the transmitted data is indexed in a data store on the device according to its attributes, and a scoring algorithm of the scheduling system determines when and how the content will be displayed within the ticker on the device. For example, because the user has indicated a strong preference for Peet&#39;s coffee, and the user is only fifty yards away from the retail store, the scheduling system, having considered the device location, rules that may have been received in metadata associated with the content, and user preferences, determines that the content should be displayed within the ticker immediately in a red font, and the device could emit an audible tone and/or vibrate to notify the user that actionable content pertaining to an important preference has arrived in the ticker. Other presentation attributes of the location-based content are also possible. Furthermore, because the location-based ticker server is aware of the preferences of the user, in this case it recognizes that there is a strong possibility that the user may wish to take advantage of the promotional coupon, and it transmits this supplemental content, including the promotional coupon, to cache memory on the cell phone. The user may then click on the Peet&#39;s ticker item to cause the supplemental content in cache memory, including, for example, walking directions and the promotional coupon, to be displayed on the cell phone screen or in a web browser on the phone. 
     Significantly, the location-based, context-aware content can be obtained from multiple content sources using any of a number of data transmission modes or “bearers”, depending on the configuration of the device. For example, as the user changes location, a cell phone equipped to communicate with a cellular telephone system and to sense the wireless access points of both Bluetooth and 802.11 networks may obtain stock quotes via an SMS text message, art exhibit content via Bluetooth, and a discount coupon from a nearby retailer associated with an 802.11 network. Data from all of these sources can be transmitted to the device in such a way as to avoid interfering with the other communication services of the device and without the user having taken any action. For example, a location-based content update can be sent to the ticker on the cell phone when it is idle. The user can then view, navigate, and interact with the location-based ticker items while engaging in a telephone call or other communication session by using one or more buttons or soft keys on the mobile device to navigate the ticker. 
     In view of the foregoing, the systems and methods of the invention can recognize the geographical location of a communication device and based on the geographical location and other considerations, populate a ticker running on the communication device with location-based, context-aware content. This represents a significant improvement over conventional ticker systems, which fail to take the geographic location of the user into account when populating tickers. Moreover, the ticker systems of the invention are interactive in a way that has not been possible using conventional ticker systems. The tickers of the invention can display news, weather, advertisements, promotions, tourist attraction information, conference room booking information, and special event information, from multiple content sources, to mobile communication device users and stationary computer device users alike. MMS messages email messages and other content may be sent to the ticker from external sources or the device user might send them to his own ticker as a form of “reminder” or “to do” list, for example. The content can be personalized to varying degrees, depending on its source and the method used to transmit it to the device. 
     These and other aspects of embodiments of the present invention will become more fully apparent from the following description and appended claims.

     DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION 
     Reference will now be made to the drawings to describe various aspects of exemplary embodiments of the invention. It should be understood that the drawings are diagrammatic and schematic representations of such exemplary embodiments and, accordingly, are not limiting of the scope of the present invention, nor are the drawings necessarily drawn to scale. 
     In general, embodiments of the invention are concerned with recognizing the geographical location of a communication device, and based on the geographical location, user preferences, vendor advertising campaign rules, device configuration and other considerations, providing location-based, context-aware content to a ticker on a communication device. Communication devices that may be employed in conjunction with the invention include PCs, televisions, landline telephones, cellular telephones, PDAs, laptop computers and any other device having a display device and suitably equipped to establish communication with a network. In particular, exemplary embodiments of the invention are directed to the use of mobile communication devices in conjunction with the invention. However, the invention should not be construed to be limited to the use of mobile communication devices. As noted previously, content can be transmitted to the communication device using any of a number of data transmission modes or “bearers” including, but not limited to cellular networks, internet protocol (IP) networks such as the Internet, the Short Message Service (SMS), satellite and terrestrial radio broadcasts, the 802.11 family of wireless local area networks, and Bluetooth networks. For convenience, 802.11 networks and Bluetooth networks may be referred to herein as “wireless access points”. Furthermore, various content delivery mechanisms that operate in conjunction with a bearer are supported by the ticker, including multimedia messaging service (MMS), really simple syndication (RSS), and email, among many other content delivery mechanisms. 
     Embodiments of the invention include content gateways through which some content providers make content available to users of the location-based ticker service. Other content providers, such as product vendors with products and services to advertise, may register with the location-based ticker system and input marketing and advertising campaigns into the system. Methods of the invention allow users to subscribe to the location-based ticker service of the invention, express preferences for certain types of content, and block other types of content. Filters residing on the communication device manage receipt of location-based content on the device in accordance with user preferences. Depending on the metadata and other rules associated with the transmitted advertising, promotions and other location-based data, the data may then be scheduled for display within the ticker on the device. Methods of the invention provide for a scheduling mechanism that employs a scoring algorithm to, among other things, reconcile the display rules of content competing for display time in the ticker and determines which content is displayed within the ticker, at what time, in what order and with what frequency. Furthermore, the manner in which the transmitted data is displayed can include a wide variety of content presentation attributes, including the shape, size, speed and location on the display screen of the ticker, multiple font effects, and audible or tactile notifications indicating that new location-based content has arrived at the ticker. Finally, the methods of the invention provide an accounting system to track and report activities associated with ticker usage. 
     I. Operating Environments and Associated Devices 
     With particular attention now to  FIG. 1 , one exemplary implementation of an operating environment, denoted generally at  100 , is indicated. Although this exemplary operating environment comprises multiple types of networks, including a cellular telephone network, wireless access points for 802.11 networks and Bluetooth networks, and broadcast networks such as FM radio or satellite radio, the invention may be employed in connection with any other type of network and associated devices that are effective in implementing or facilitating wireless communication or landline communication. While  FIG. 1  depicts a cellular telephone and exemplary embodiments are directed to the use of cellular telephones in conjunction with the invention, the invention should not be construed to be limited to such devices. As previously noted, PCs, televisions, landline telephones, cellular telephones, PDAs, laptop computers and any other device suitably equipped to establish communication with a network and having a display device may be used to implement the methods of the invention. Accordingly, the scope of the invention should not be construed to be limited to the exemplary operating environment indicated in FIG.  1 . 
     In the exemplary illustrated embodiment, the operating environment  100  includes one or more mobile communication devices  101  configured to communicate with one or more networks and/or network elements, including base transceiver station (BTS)  102  of the cellular network, IP network  108 , FM or satellite radio broadcast network  112 , 802.11 wireless access points  116 , and Bluetooth wireless access point  118 . Mobile communication device  101  may determine its geographical location using positioning techniques such as a global positioning system (GPS) or wireless-assisted GPS, for which it uses one or more satellites  114 . Its location can also be determined by other methods, such as triangulation of the signal from the cell sites serving the mobile device or by simply encountering an 802.11 or Bluetooth wireless access point, which effectively positions the device. Alternatively, the device location may be determined by querying another server on the network that contains location information about the device. The location of landline devices may be explicitly specified by the device user through submission of an information profile to the location-based ticker service. Mobile communication devices  101  are further configured with ticker client software that enables them, among other things, to communicate with ticker server  300  that may be embodied, in one implementation, as a server operating in conjunction with IP network  108 . Ticker server  300  may further interface with other network elements, such as a Short Message Service Center (SMSC) and various gateways to implement the methods of the invention. 
     II. Multiple Bearers, Content Delivery Mechanisms and Receiving and Displaying Location-Based Content 
     Directing attention now to  FIG. 2 , details are provided concerning an example of ticker client software  200 . Ticker client software  200  resides on the communication devices used in conjunction with the invention. In the exemplary embodiment, ticker client software  200  is installed on mobile communication device  101 , which is suitably equipped to establish a connection with one or more networks and send and receive data. Ticker client software  200  operates in conjunction with a ticker server discussed in more detail below. 
     Ticker client software may include filter  202 , meta tagging mechanism  204  and security system  206 . Location-based content can become available to ticker client software  200  operating on mobile communication device  101  from multiple content sources and over various types of network connections. In one case, content providers may supply location-based content through various gateways to ticker server  300  or content providers may alternatively submit product and service content to the location-based ticker server directly. In either case, the location-based content may then be transmitted to ticker client software  200  using any of a number of bearers for example, a data connection over a cellular network, and SMS. Alternatively, location-based content can be supplied to ticker client software  200  directly, without having first been aggregated at ticker server  300 . For example, a user of mobile communication device  101  enabled with ticker client software  200  and equipped with a Bluetooth chipset may receive location-based content directly when it encounters another Bluetooth device. Bluetooth is a wireless technology typically used for short range communication of data and voice from one device to another, usually within a small area. One example of such an application would be the ability to receive into the location-based ticker a detailed description of an art exhibit being viewed by the user. In this case, the content sent to mobile communication device  101  is both location-based and context-aware, in that the device automatically senses the wireless access point of the Bluetooth network and receives content specific to the context, in this case an art exhibit. In addition to communicating the ticker content directly to the device using one of the aforementioned bearers, it could deliver it using any of a number of content delivery mechanisms such as email. For example, when mobile communication device  101  communicates with the Bluetooth access point, it might provide its email address to the art exhibit system. The system could then send specific content to that email address with special codes indicating that it is to be interpreted by the ticker software on that device. Mobile communication device  101  may further be configured to interact with the 802.11 family of wireless local area networks, and when it encounters a wireless access point of such a network it can similarly receive location-based, context-aware content such as a promotional coupon for a nearby restaurant, and then display it in the ticker at 12 p.m. or at another user-specified lunchtime. Ticker client software  200  may also monitor broadcast networks such as FM radio and satellite radio and “pick and choose” content that is relevant to the user. 
     Generally, the value of utilizing multiple bearers is that some transmission mechanisms are better suited to delivering certain types of content than others. In some cases, the location-based ticker system may select a bearer based on the nature of the content itself. For example, a very small data payload that should be delivered in “real-time” or near real-time, such as a local traffic alert, may be delivered using broadcast SMS. Conversely, a data payload that is larger in size and that contains personalized content, such as tourist site information that includes a review of a nearby restaurant and a discount coupon, may be delivered over an IP connection. In other situations, the fastest way to obtain real-time data, such as a baseball score, while using the least amount of communication device overhead may be for the ticker client software to obtain the baseball score from a satellite or terrestrial radio broadcast. Furthermore, highly personalized content, regardless of the size of the transmission, may be more appropriately delivered over a cellular network using a data connection. It should be noted that regardless of the location-based content source or bearer used, the content is typically transmitted to mobile communication device  101  at a time when the device is not otherwise engaged in a communication session to avoid any disruption in communication. Content may also be transmitted at a time when network traffic load is considered to be off-peak in order to conserve bandwidth, or a bearer may be chosen based on network traffic loads. 
     In any case, when location-based content becomes available from a source that is external to ticker client software  200 , filter  202  evaluates it to determine if it should be received. Security element  206  further examines the available content to ensure it is from a credible source. If filter  202  decides, based on rules and preferences  210  that the content should be received, and security  206  further endorses receipt of the content, meta tagging module  204  may associate metadata with the content, which describes the attributes of the content being received and which may be in addition to metadata already associated with the content by the content provider. The content is then received into data store  208  and indexed in data store  208  according to its attributes. The aforementioned rules and preferences  210  are specified by the user upon registration and/or subscription with the location-based ticker service to assist in controlling and managing receipt and display of location-based content within the ticker. Among other things, the user can express preferences for certain types of content or the user may block receipt of certain types of content or content sources. The user can further specify preferences for the form taken by the ticker, such as its shape, size, and location on the display of mobile communication device  101 . Rules and preferences  210  can be modified by the user at any time. In addition, the location-based ticker service can modify what is displayed to the user based on a history of ticker items the user has previously interacted with, thus inferring the user&#39;s preferences. The history of the ticker activity, the explicit user preferences and rules, and other criteria other than geographic location, are referred to herein collectively as “user criteria,” which can be used to filter incoming location-based content and to determine whether and when to display the content on the ticker. 
     Once received into data store  208 , scheduler  212  determines the time at which the location-based data will be displayed relative to all of the data received and scheduled for display within the ticker. In some cases, location-based content may be displayed immediately after its receipt into data store  208 , based on the ticker server&#39;s knowledge of the device location. In other cases, location-based content is received and stored in data store  208  for a period of time before it is displayed within the ticker. In this case, content engine  224  of ticker client software  200  is responsible for periodically checking the location of the device and then interfacing with data store  208  to search for matches between the current location of the device and available content. In still other cases, the immediacy of an encounter between a WLAN and the mobile communication device causes location-based content to be received and displayed within the ticker. In all of these cases, scheduler  212  is responsible for determining the timing and order in which all of the available location-based content is displayed in the ticker of mobile communication device  101 . 
     In addition to location-based content received from sources external to the mobile communication device  101 , local applications  220  operating on the device  101  can also generate data and submit it to scheduler  212  to be scheduled for display within the ticker. For example, a calendar application may send an appointment alert to scheduler  212  for display within the ticker. The scheduler is able to take into account the time sensitivity of the data and schedule its display within the ticker accordingly. 
     With continuing attention to  FIG. 2 , content manager  214  interfaces with data store  208  to manage the ticker content. For example, the content manager keeps only the latest score in a sports game and deletes previous versions. It also deletes old or expired content or content that the user has viewed and should be deleted based on rules contained in the metadata. In one example, a news alert about a particular event may be stored and scheduled for display in the ticker at a particular time. If updated content is subsequently received in data store  208 , content manager  214  ensures that the most recent news alert is displayed in place of the older content already scheduled for display. 
     Rendering engine  216  of ticker client software  200  receives input from rules and preferences module  210  concerning the look and feel of the location-based content displayed on mobile communication device  101 . For example, the user may want the location-based content to appear in the “traditional” ticker format, wherein it scrolls horizontally across the bottom of the display screen. Alternatively, the user may wish to view the location-based content as a rotating, three-dimensional box, with each face of the box showing a different category of location-based content. The ticker may display special attributes such as transparency, which allows the user to see through the ticker to what is displayed behind it. The user may further specify that certain categories of location-based content be displayed passively within a scrolling, horizontal ticker, whereas other categories of location-based content should be displayed in a more dramatic way, such as with specialized font attributes, in a particular color, and with accompanying animations, such as “entrance” animations. 
     Presentation effects including contrasting font color, “new” graphics, a change in the order of presented items and audible and tactile alerts may be used to denote new location-based content received. A “free form” ticker could be employed in which new, location-based content “flies” onto the display screen without being contained within the specified ticker format(s). Similarly, location-based content can “fade in” or “fade out” from the display screen, or “builds” may be used in which fragments of content are displayed one after the other, rather than all at the same time, until the complete content is displayed. In one example, rendering engine  216  could be instructed to display a particular local traffic update with an entrance animation that flies across the display screen and flashes. The entrance animation could be further accompanied by an audible or tactile notification, such as a ring tone or device vibration to alert the user of a traffic accident on the user&#39;s transportation route. Rendering engine  216  may further implement numerous attributes and effects pertaining to the shape, size, location, scroll speed, font attributes, color schemes and themes of the location-based content displayed in the ticker and of the behavior of individual location-based ticker items or categories of location-based ticker items and render them on the display of mobile communication device  101  accordingly. 
     III. Ticker Interaction and Use 
     With continuing reference to  FIG. 2 , the ticker of ticker client software  200  may be interactive. Action dispatcher  218  manages user interaction with the ticker and interfaces with the rest of the communication device on which the ticker is hosted in response to user interaction with the ticker. In one case, the user may employ ticker navigation effects, such as scrolling through the ticker at a faster rate, skipping items, or even deleting ticker items by pressing a single button on the mobile communication device. User interaction with an item displayed within the ticker, (a “location-based ticker item”) such as by clicking on the item, scrolling to it, highlighting it or otherwise selecting the item, can cause a secondary action. In one example, a URI associated with the location-based ticker item is launched when the user selects the item, such as by clicking on the item, resulting in display of a web page containing additional content about the item. In another the user approaches his favorite video store, he may receive an advertisement in the ticker announcing the availability of a new movie available for rent. Any of a number of content delivery mechanisms, including multimedia messaging service (MMS) and really simple syndication (RSS), can be supported by the ticker, and in this example the advertisement may be sent using the MMS as the content delivery mechanism. Selection of the advertisement can give the user the option of downloading a Java application for example, which is a movie trailer. The user may then wish to send an email or other message to the store to reserve the movie. The action dispatcher  218  interfaces with the appropriate external systems to manage download of the Java application and dispatch of the message to the store. Once the movie trailer is downloaded, it can be viewed on the communication device. Another example of interactive ticker use is to conduct a poll or a survey. Users leaving the premiere of a new movie could be presented with a poll in the ticker. Clicking on certain items in the ticker would indicate the user&#39;s response to the questions in a poll. Similarly, users could receive a customer satisfaction poll upon leaving a retail store from which they have purchased a product or service. Additionally, selection of the previously mentioned appointment notification displayed in the ticker can cause the calendar application to be launched so the user can view the full details of the impending appointment, and receive driving directions to the appointment based on his current location. 
     Finally, ticker client software  200  employs usage accountant  222  to monitor and track the location-based data displayed within the ticker and the various ways in which the user interacts with the location-based ticker items. For example, selecting an advertisement for a new restaurant may result in driving directions being displayed in a WAP browser, and the user may further be presented with an option for automatically dialing the restaurant phone number to make a reservation. The usage accountant  222  monitors and reports on the transaction so the advertiser receives feedback about response to the advertisement. In this case, whether or not the user dials the phone number is a very important piece of information for the advertiser. At the same time, the selection of the ad by the user is accounted for so the advertiser of the restaurant can be charged, as with pay-for-performance advertising business models. In addition to monitoring and reporting on transactions that result in billing activity, user interaction with location-based items in the ticker is also aggregated in order to better understand user preferences, supply the user with location-based content which is even more finely tuned over time to meet user needs, and to maximize the effectiveness of advertising campaigns. The usage information is periodically reported to usage accounting  304  of ticker server  300 . Moreover, the user may view a historical record of ticker items displayed and a history of interaction with the ticker by selecting an icon in the ticker that serves a web page or otherwise provides a report with the historical ticker data to the user. 
     IV. Registration, Content Aggregation and Campaign Management 
     With reference now to  FIG. 3 , details are provided concerning an exemplary implementation of ticker server  300 . In the exemplary embodiment, ticker server  300  operates in conjunction with a plurality of content providers and mobile communication devices  101 . To gain access to the location-based content offered by the plurality of content providers, ticker client software  200  resident on mobile communication device  101  registers with device registration and location tracker module  312  of ticker server  300 . Using user interface elements of ticker client software  200 , the user of mobile communication device  101  may further express rules and preferences concerning the type of location-based content in which s/he is interested and the manner in which it should be displayed within the ticker on the device. Once expressed, the rules and preferences may be stored on mobile communication device  101  in rules and preferences module  210 , in rules and preferences module  308  of ticker server  300 , or both. Along with specifying rules and preferences, a user of a landline communication device such as a PC or telephone may also indicate the geographical location of the device by completing an information profile during the registration process. Once initial registration is completed, device location information can be provided to location tracker module  312  and ticker client software  200  may begin receiving location-based content. 
     In the exemplary embodiment, ticker server  300  aggregates some content, but as previously noted, other content may be delivered via other means to ticker client software  200  on mobile communication device  101 . Content providers may become members of the location-based ticker service by registering with the service using membership manager  310 . Once registered, content can be provided to the ticker server for distribution to registered mobile communication devices  101 . In some cases, content providers can deliver content directly to the ticker client software, and in some situations the user may be prompted to accept or reject the location-based content that is available for provision directly to the ticker client software. 
     With continuing attention to  FIG. 3 , content can be delivered to ticker server  300  in various ways. First, content providers, including large entertainment conglomerates such as MTV and Disney, as well as smaller, independent content providers, may feed content to the location-based ticker server through content aggregator gateway  316  that provides a means for potentially disparate content servers to interface with ticker server  300 . Content received via content aggregator gateway  316  may then be stored in data store  314 . Alternatively, vendors of products and services may choose to input company and product information, as well as advertising and promotions into campaign manager  306  of ticker server  300 . In another embodiment, a third party marketing campaign management system may interface with ticker server  300  to deliver content to data store  314 . Campaign manager module  306  provides vendors and other content providers the capability to create and manage marketing campaigns for their products and services. Product and service information may be input via a web page and can include details such as the message to appear on the ticker, which customers should see which messages, product descriptions, competitive comparisons, promotional discounts and other information. Terms of use, pricing, promotion duration, and other marketing and advertising campaign details can be specified, implemented and updated using campaign manager  306 . In some cases, the content can be encrypted before it is transmitted to the communication device. Decryption can be performed, for example, by transmitting a key from a local access point in the network to the mobile communication device at an appropriate time or location to enable the mobile communication device to decrypt location-based content that it already has. 
     Once the encrypted content is downloaded to data store  208  of ticker client software  200  (reference  FIG. 2 ), when the device arrives at the specified location and at the specified time, campaign manager  306  can initiate transmission of a key to the communication device to “unlock” the content such that it can be displayed within the ticker. Campaign manager  306  further provides capability for receiving feedback from usage accountant  222  of ticker client software  200  (see  FIG. 2 ) and reporting on how many users have responded to vendor campaigns by interacting with the ticker. In any case, metadata, such as target user demographics and terms and conditions, may be provided along with the content provided to ticker server  300 . For example, an automobile manufacturer may specify that its advertisement for a newly released vehicle be sent to communication devices within a certain proximity to a dealership to encourage the user to stop by to view the new vehicle. It may further specify the age of the recipient and also send a special promotional offer to users who are previous buyers from the manufacturer and whose lease agreements are close to expiring 
     Security and authentication module  302  provides a variety of security services, including secure registration and authentication both for communication device users and for content providers, as well as monitoring the source of incoming content to ensure that only credible, registered users are interacting with the location-based ticker server and that only authenticated content is delivered to the ticker client. 
     Usage accounting module  304  performs a variety of processes related to tracking the use of the content provided to ticker client software  200 , including receiving usage data from usage accountant  222  (depicted in  FIG. 2 ) of ticker client software  200  and exporting usage data to external billing, reporting, and campaign management systems. 
     Turning now to  FIG. 4 , one embodiment of a process  400  is illustrated that is concerned with initial registration and location of mobile communication device  101 . In operation, mobile communication device  101 , which is configured with ticker client software  200 , establishes a network connection in the conventional manner. At stage  402 , ticker client software  200  is invoked in response to the user powering on mobile communication device  101  or by pressing a button, a soft key or issuing a verbal command to the device. At stage  404 , the user is prompted by ticker server  300 , which has established communication with ticker client software  200 , to register with the location-based ticker service. At stage  406 , the user provides registration information, including billing address, device information, and content preferences, including ticker and content presentation attributes, and any other information requested by ticker server  300  in conjunction with location-based ticker service registration requirements. Upon completion of stage  406 , ticker client software  200  of mobile communication device  101  is prepared to receive location-based content. At stage  408 , location tracker  312  of ticker server  300  (see  FIG. 3 ) obtains location information for mobile communication device  101 . In one case, mobile communication device  101  determines its location using any of the aforementioned positioning techniques known in the art and reports its location to location tracker  312 . In other cases, location tracker  312  may query one or more network elements, such as a home location register (HLR), a visiting location register (VLR) or another element in the network to obtain location information for mobile communication device  101 . 
     Turning attention now to  FIG. 5 , a process for providing location-based content from ticker server  300  to ticker client software  200  on mobile communication device  101  is illustrated. In one embodiment of the invention, location-based content can be selected for scheduling and display from local data store  208 , from ticker server data store  314 , or both. In operation, ticker client software is invoked at stage  500  either automatically by powering on mobile communication device  101 , pressing a button or soft key on the device, or by a voice command. At stage  502  the ticker client software establishes its location. Once the geographical location of mobile communication device  101  is determined by ticker client software  200 , the process can proceed along two different paths and the paths can be executed simultaneously. At stage  504  the ticker client reports its location to location tracker  312 , of location-based ticker server  300 , which causes a query to run at stage  506  against data store  314  to search for relevant location-based content. At stage  508  a decision is made as to whether there is a match between available content and the user&#39;s location and/or preferences. If a match is found, at stage  510  the content can be sent to data store  208  of ticker client software  200  using any of a number of transmission methods previously mentioned. In some cases, content that is low priority may be transmitted to ticker client software  200  at a time that is determined to be an off-peak time for network traffic, that is, the location-based ticker server has access to information about network loads such that it can determine peak and off-peak times with regard to traffic load and transmit the content accordingly based on its priority. Although not depicted, filter module  202 , meta tagging module  204  and security module  206  may be employed to validate the source of the content and associate metadata with the content before it is stored in data store  208 . Meanwhile, at stage  512 , having established the location of the device, content engine  224  can query data store  208  of ticker client software  200  to search for relevant content already stored on the device pending display, and for newly received location-based content. The process continues at stage  514  where it is determined whether any of the content in data store  208  is a match for the user&#39;s current location and/or preferences. If it is determined that there is a match, the content is sent to scheduler  212  at stage  516  and prepared for display within the ticker. 
     With reference now to  FIG. 6 , a process is illustrated for receiving location-based content via a broadcast medium, an 802.11 network or a Bluetooth network. In one embodiment, invoking the ticker client software at stage  600  causes it to automatically attempt to detect a wireless access point. At the same time as it is attempting to detect wireless access points at stage  602 , at stage  604  it can also monitor various types of broadcasts, such as FM broadcasts or satellite radio broadcasts for relevant, location-based content. At stage  606 , ticker client software determines if any wireless access points are available from which to receive location-based content. If wireless access points are available, they can begin sending content to ticker client software. At stage  608 , ticker client software filters incoming location-based content for relevancy and credibility. In one embodiment, the user can be prompted by security module  206  of ticker client software  200  to explicitly approve incoming content as depicted at stage  610 , however this stage is not required and rules pertaining to approval of content can be specified by the user. In this case, if the user rejects the incoming content, the process returns to stage  602  and  604  wherein ticker client software “monitors” various broadcasts and continues to look for wireless access points. If the incoming content is accepted by the user at stage  610 , the process continues to stage  614  in which the content is sent to the data store of the ticker client software. Although not depicted, meta tagging module  204  may assign metadata to the incoming content describing its attributes so it can be properly indexed in data store  208 . The content is then sent to the scheduler and scheduled for display within the ticker. 
     V. Content Priority Scores 
     With reference to  FIG. 7 , details are provided concerning the process of using an algorithm employed by scheduler  212  of ticker client software  200  (see  FIG. 2 ) to determine the timing, order, and frequency with which location-based content received into data store  208  is displayed within the ticker. Conditions such as strength of user preferences, time sensitivity of the content, degrees of relevance of the content, proximity to a location pertaining to the content, how often the content has been shown, content provider business arrangements, marketing campaign rules and other conditions are evaluated and a numerical value reflecting the priority of the location-based content is assigned to the content. Content with the highest score is displayed within the ticker on mobile communication device  101  first, and if the score surpasses a certain priority threshold, presentation attributes, such as contrasting font colors or notifications may be applied to the displayed content. 
     For example, three items (advertisement for Peet&#39;s coffee, updated stock quote, and an ad for McDonalds) are identified as being candidates for display on the ticker at stage  700 . The scoring system calculates a relevance score for each item at process  702  based on a number of system-defined attributes; in this case proximity, user preferences (our user loves coffee and follows the stock market), and the advertising rate paid by the advertiser are the attributes considered in the calculation. The process  702  of calculating the relevance score includes calculating a value vector for each of these three attributes for each item in stage  704 . Using a scale from 0 to 100 as an example, the score for Peet&#39;s might be (50, 100, 50) since the user is a few blocks from the coffee shop, has specified a strong preference for Peet&#39;s brand coffee, and the advertising fee being paid by Peet&#39;s is in the middle of the range of advertising fees paid. For the stock quote, the value vector might be (0, 100, 0), since proximity does not apply and no advertising fee is being paid, and for the McDonalds ad the value vector is (0, 0, 75) since the user is not near a McDonalds, nor has the user expressed a preference for McDonalds, but McDonalds is paying a very high advertising rate to promote their new product in the ticker display. 
     Given these three value vectors, an attribute weighting is then applied in stage  706  of the process  702  of calculating the relevance scores. In this example, proximity is most important and has a weight of 100, user preferences are the next most heavily weighted attribute with a weight of 80, and the advertising fees paid are assigned a weight of 50. A score can now be calculated for each of these items, which will determine the order in which the items are displayed in the ticker according to stage  708 . In addition, the relevance scores can be used to determine in stage  710  whether to apply presentation attributes to the items when they are displayed on the ticker in stage  712 . The calculations for these items in this example are as follows: 
     Peet&#39;s: 50*100+100*80+50*50=15500; 
     Stock quote: 0*100+100*80+0*50=8000; 
     McDonalds: 0*100+0*80+75*50=3750. 
     Thus, in this example, the Peet&#39;s item would be displayed first, the stock quote second, and McDonald&#39;s last. These scores can also be used to determine how often to show content. In this example, the device might show the Peet&#39;s coffee item twice as often as the stock quote, and four times as often as the McDonald&#39;s item. Of course other scoring systems and scheduling systems could be used, and the specific parameters can be highly customized for the particular application. 
     VI. Telecommunication Devices and Computing Environments 
     Embodiments of the present invention may be implemented in connection with a special purpose or general purpose telecommunications device, including wireless telephones and other telephony-enabled mobile devices, landline telephones, or special purpose or general purpose computers that are adapted to have telecommunications or data networking capabilities such as cable set top boxes or PCs.
