CROSS-REFERENCE TO RELATED APPLICATIONS This is a continuation application of U.S. Non-provisional application Ser. No. 09/630,134 entitled METHOD AND SYSTEM FOR DELIVERY OF A CALLING PARTY'S LOCATION filed Aug. 1, 2000, the contents of which are herein incorporated by reference.
BACKGROUND The present invention relates to telecommunication systems, and in particular, to caller name delivery services and networks that track the location and identity of network devices.
The benefits of calling name delivery (CNAM), also known as caller identification or caller ID. CNAM enables a called party to view information about a calling party on a display unit, which is typically a liquid crystal display (LCD), a light-emitting diode (LED) display, or a comparable device. The displayed information generally includes at least the calling party's name, the calling party's directory number, and the date and time of the call.
Referring to FIG. 1, CNAM is typically implemented in the following manner. A calling party 101 picks up the telephone and dials the directory number of a called party 102, which is 404-555 2222. Called party 102 is a CNAM subscriber having a CNAM display unit 116. CNAM display unit 116 could be separate from or integral to the device of called party 102. After calling party 101 dials the directory number, an central office 104 (also referred to as a service switching point) serving calling party 101 obtains routing information and populates an initial address message (IAM) with certain information. The IAM is a parameter that exists within an integrated services digital network user part (ISUP) signaling message. The IAM is a defined message type from TR-NTW-000246 and ITU Q.764/Q.767, and is one of a sequence of messages used in ISUP trunk signaling. An ISUP signaling message employs a Common Circuit Signaling System 7 (CCS7) call setup protocol. In particular, the IAM is populated with the directory number of calling party (404 555-1111), the directory number of the called party (404-555-2222), and a presentation parameter. In this case, the presentation parameter allows a CNAM display.
Central office 104 then sends this routing information in the signaling message to a central office 106, which serves called party 102. Recognizing that the call is for a CNAM subscriber, central office 106 halts the calling process to launch a calling name query 150 on the CCS7 network. As a part of the query launch, central office 106 populates a called party address parameter in query 150 with the directory number of calling party 101, in this case 404-555-1111. The called party address parameter is a routing parameter within an Advanced Intelligence Network (MN) query package.
After central office 106 has populated the called party address parameter, calling name query 150 is sent to a signaling transfer point (STP) 108. STP 108 performs a global title translation (GTT) on the called party address parameter to determine to which service control point (SCP) calling name query 150 should be routed. This determination is made based on the first three digits (the numbering plan area, or NPA) in the directory number of calling party 101, which 2 in this case is 404. STP 108 then forwards the calling name query to the appropriate SCP 112 through CCS7 Network 110. SCP 112 searches a CNAM database 114 for calling party's record from which SCP 112 retrieves the associated name. CNAM database 114 is preferably a part of SCP 112, as shown in FIG. 1, but may be separate from SCP 112, or incorporated as part of another network element such as a service node or a switch.
The principal advantage of conventional CNAM services is the ability to screen calls. Upon receiving a call, a called party can review the information on the display unit and decide whether or not to answer the call. However, users wanting to screen calls and fulfill other location-sensitive purposes often prefer to know more about the calling party than just name, number, date, and time. For instance, a service dispatcher monitoring the activities of his service technician may wish to receive the exact location of his technician each time the technician calls in, so as to facilitate efficient scheduling of the next 3 assignment. Although the name and number on the CNAM display unit could possibly provide clues to the technician's location, the dispatcher would prefer seeing a more precise and easily understandable description of location, e.g., a street address or building name. Thus, although the typical CNAM information may be suitable for simple call screening, many telephone users would prefer to receive even more information about the calling party.
BRIEF SUMMARY The present invention is a method and system for providing a service that delivers location information associated with a caller. The service operates in both wireline and wireless networks, providing called parties with the location information of calling parties who use either stationary or wireless telephones. The service can operate as a stand alone service or can be a part of a CNAM service, delivering location information in addition to the conventional name, number, date, and time. In conjunction with any call, the present invention reports to the called party, the location from which the calling party is calling. Therefore, a subscriber can use the valuable location information to better screen calls and to fulfill other location-sensitive purposes.
The primary components of the present invention include a service control point, an address database in communication with the service control point, and a network that tracks the locations of network users. The service control point operates within a PSTN in cooperation with other MN components, such as signal transfer points and service switching points. The address database operates within the location-tracking network and allows access by the service control point to its contents. The location-tracking network interfaces with the PSTN to terminate calls between location-tracking network users and PSTN users. For example, for a wireline network, central offices 4 provide this interface. As another example, for a wireless network, mobile switching centers (MSCs) provide this interface. As another example, for voice over Internet protocol (VoIP) calls, an Internet protocol network and an IP-to-PSTN gateway provide the interface.
The service control point performs service logic in response to a query requesting the location of a calling party. The service control point can also execute logic in response to a query for the caller name.
The service control point accesses the name database (for CNAM) and the address database (for location information delivery). In response to queries, the service control point also returns routing instructions to direct the service switching points how to terminate a call and to provide CNAM and location information for presenting on a display unit.
The location-tracking network is a call carrier that tracks the locations of its users and maintains the information in the address database. For example, the location-tracking network could be a wireline network that records the location of stationary terminal devices upon service activation. As another example, the location tracking network could be a conventional wireless network providing such services as paging, digital cellular, and personal communications services (PCS). To track location of wireless network users, the wireless network would use, for example, handheld device location systems or network-based location systems. As another example, the location-tracking network could be an Internet protocol network, in which location could be an email address.
Alternatively, in addition to location delivery, the present invention could also include searching a name database in communication with the service control point for the calling party's identifier to determine the calling party's name, returning the calling 7 party's name, and displaying the calling party's name on the display unit.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a prior art schematic diagram illustrating the CNAM operating environment.
DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS The present invention is a location delivery service for called parties. The invention provides subscribing called parties with location information about calling parties, for both stationary terminal devices (e.g., wireline) and mobile devices (e.g., wireless). The location delivery service enables a subscriber to more effectively screen calls and to satisfy other location-sensitive purposes. The present invention contemplates future enhanced digital cellular networks that will track the identity and location of each wireless network user.
The system of the present invention provides location delivery using at least a service control point, an address database in communication with the service control point, and a network that tracks the locations of network devices. If the location-tracking network provides location information in a form unsuitable for display on a display unit, the system further includes a mapping converter in communication with the service control point. The method of the present invention varies according to whether a calling party is a stationary terminal device (e.g., wireline) or a mobile device (e.g., wireless). The system architecture of FIG. 2 a and the corresponding flowchart of FIG. 2 b illustrate the location delivery service for a wireline call from a stationary terminal device, according to a preferred embodiment of the present invention. The system architecture of FIG. 3 a and the corresponding flowchart of FIG. 3 b illustrate the location delivery service for a wireless call from a mobile 9 device, according to another preferred embodiment of the present invention.
Referring to FIG. 2 a, the primary components of the stationary terminal device embodiment of the present invention include SCP 200 and address database 202. Address database 202 is a part of location-tracking network 201 and contains a location description for the location-tracking network terminal devices (e.g., telephones) organized by directory number. SCP 200 is in communication with address database 202 and is specially programmed to perform location delivery logic. Specifically, in response to a query requesting location information, SCP 200 reads the calling party information embedded in the query, and consults address database 202 for the calling party's location (i.e., the location of the calling party's wireline network terminal). SCP 200 returns routing instructions including the location of the calling party.
Optionally, the query also asks for call name delivery information, in response to which SCP 200 consults name database 114 for the calling party's name and SCP 200 returns the name and telephone number of the calling party along with the location information.
Address database 202 and name database 114 are preferably maintained by location-tracking network 201 as shown in FIG. 2 a, whereby network user names and locations are stored upon service activation and SCP 200 is given access to the information.
Alternatively, the network of SCP 200 could maintain address database 202 and name database 114.
Referring to FIGS. 2 a and 2 b, in step 260, calling party 101 dials the directory number of a called party 102 (404-555-2222).
Called party 102 is a CNAM subscriber having a display unit 117. In step 262, central office 104 serving calling party 101 obtains routing information, populates an initial address message (IAM) with the directory number of calling party 101 (404-555-1111), the directory number of the called party 102 (404-555-2222), and a presentation parameter (in this example) that allows a CNAM display. In step 264, central office 104 sends this routing information in the signaling message to central office 106, which serves called party 102.
In step 266, the signaling message activates a trigger on central office 106 set for calls to a CNAM and location delivery subscriber (the called party). The trigger launches a query 250 asking for the name and location of the calling party, and including in the called party address parameter the directory number of calling party 101, 404 555-1111. In step 268, central office 106 sends query 250 to STP 108, which performs a global title translation on the called party address parameter and determines that query 250 should be routed to SCP 200. STP 108 then forwards the query 250 to SCP 200 through CCS7 Network 110 in step 270.
In response to query 250, in step 272, SCP 200 searches name database 114 for calling party 101's record, from which SCP 200 retrieves the associated name. SCP 200 also searches address database 202 for calling party 101's record from which SCP 200 5 retrieves calling party 101's location information.
In addition, although calling party 101 is shown as a part of a separate location-tracking network 201 in FIG. 2 a, one of ordinary skill in the art would appreciate that calling party 101 could be within the same network as called party 102. In such case, address 12 database 202 and name database 114 would also be within the same network.
In an alternate preferred embodiment of the present invention, the calling party is a stationary VoIP telephone, instead of a stationary wireline telephone, and the location-tracking network is an IP network (shown generally as 299). As shown in FIG. 2 c, VoIP telephone 290 is in communication with IP network 292. IP network 292 is in communication with name database 114 and address database 202 and maintains the information within the databases. To facilitate calls to and from the circuit-switched PSTN network, IP network 292 is in communication with central office 106 through gateway 294. Gateway 294 handles IP to PSTN conversions. Within this IP/PSTN system architecture, the method for delivering location information is as described above for the stationary wireline telephone, in FIGS. 2 a and 2 b. FIG. 3 a illustrates a system architecture that provides location delivery for calling parties using mobile devices, according to a preferred embodiment of the present invention. As shown, the primary components of the mobile device embodiment of the present invention include SCP 300 and a location-tracking network 302, which in this case is a wireless network. Wireless network 302 tracks the location of wireless network devices, such as cellular telephones and interactive pagers, and records location data in address database 202 as part of each call. The methods by which wireless network 302 determines the location of a mobile wireless network device are described below. Wireless network 302 provides SCP 300 with access to address database 202. SCP 300 is specially programmed to perform location delivery logic. Specifically, in response to a query requesting location and CNAM information, SCP 300 reads the calling party information embedded in the query, which includes the calling party's directory number. Based on the directory number, SCP 300 13 consults name database 114 for calling party 101's name and address database 202 for calling party 101's location information. SCP 300 returns routing instructions including the name, telephone number, and location of the calling party.
If wireless network 302 provides location data in a rudimentary form not easily understood by a CNAM subscriber, the primary components of the wireless embodiment further include a mapping converter 304 in communication with SCP 300, as shown in FIG. 3 a. An example of a rudimentary form would be GPS coordinates, with which the typical telephone user is unfamiliar. As used herein, �raw� refers to location data in a rudimentary form, unsuitable for display on a calling name display unit. �Displayable� refers to location data already suitable for display on a display unit. Mapping converter 304 translates the location data provided by wireless network 302 into descriptions that are understandable to the typical user. For example, if wireless network 302 furnishes GPS coordinates, mapping converter 304 could translate coordinates X-Y into �101 Park Place.� In this manner, SCP 300 reads the location data provided by wireless network 302, as translated (if necessary) by mapping converter 304, and delivers the location information to display unit 117.
Although FIG. 3 a shows mapping converter 304 as a separate component within the PSTN network, one of ordinary skill in the art would understand that the functions and structure of mapping converter 304 could be located in several different places. For example, mapping converter 304 could be located within SCP 300 or within name database 114. As another example, mapping converter 304 could also be located within wireless network 302, in communication with location system or as part of location system.
Regardless of where mapping converter 304 is provisioned, the desired end result is to deliver displayable location information to display unit 117.
14 In tracking the location of network devices, wireless network 302 determines the location of a network device during origination of the call from the calling party, and records the location data in address database 202. To obtain the location data, wireless network 302 uses any suitable location system. Examples of suitable location systems include handheld device location systems and network-based location systems. One example of a handheld device location system is a GPS mounted in a cellular telephone. Examples of network-based location systems include triangulation systems and Wireless Application Protocol (WAP) location systems. Depending on the desired degree of accuracy, one or both of the location systems can be used to determine a device's location.
In step 364, MSC 306 forwards the call to central office 106, which serves called party 102. The call includes the directory number 16 of calling party 101 (404-555-1111), the directory number of the called party 102 (404-555-2222), the mobile identification number of calling party 101, and a presentation parameter that enables a CNAM display.
In step 366, the call activates a trigger on central office 106 set for calls to a location delivery and CNAM subscriber (the called party).
The trigger launches a query 350 asking for the name and location of the calling party, and including in the called party address parameter the directory number of calling party 101, 404-555-1111. In step 368, central office 106 sends query 350 to STP 108, which performs a global title translation on the called party address parameter and determines that query 350 should be routed to SCP 300. STP 108 then forwards query 350 to SCP 300 through CCS7 Network 110 in step 370.
17 Having the location information and the name of calling party 101, SCP 300, in step 378, returns the name and location associated with the directory number of calling party 101 (along with call routing instructions) in a transaction capability application part (TCAP) response 351 to central office 106 through CCS7 Network 110 and STP 108. In step 380, central office 106 terminates the call to called party 102, sending the name, directory number, and location of calling party 101. Finally, in step 382, the information, including the location of calling party 101, is displayed on called party's display unit 117, along with the date and time of the call as generated by display unit 117.
In an alternate preferred embodiment of the present invention, calling party 101 and called party 102 are wireless device users, both associated with the same wireless network or different wireless networks.
