Abstract

A system and method of providing an automatic directory service for a mobile telecommunications unit (20) is based on the geographic location of the mobile unit. A user of the mobile unit places a telephone call to a desired service/goods provider using a wireless telecommunications unit. The call first accesses a wireless switch system (16), which in turn communicates with a service platform (18). The message includes the geographic location of the mobile unit. The mobile unit is then automatically connected to the facility of the service/goods provider in closest geographic proximity to the mobile unit.

Description

DIRECTORY SERVICE BASED ON GEOGRAPHIC LOCATION OF A MOBILE TELECOMMUNICATIONS UNIT
Background of the Invention
This invention relates to a system and method for providing automatic directory service assistance for a mobile telecommunications unit based upon the geographic location of the mobile unit. As mobile telecommunication units, in particular, mobile cordless telephones, become ubiquitous, the need exists for a method and system of providing, automatically to the mobile telecommunications unit and its user, a connection to the closest facility, store, or other desired destination of the user, based on the geographic location of the mobile unit. As an alternative, the telephone number of the closest facility could be provided to the mobile unit instead of the connection being made automatically.
As more and more people travel about with cordless phones, it becomes important for the mobile unit user to know the location of a nearest store or other facility of a service/goods provider without having to consult a directory assistance provider, such as 411, for an intervening operator. Typically, the operator will not give closest store information - only a telephone number of a requested store. If the location of the closest store is not known to the mobile unit user, the 411 provider is not useful.
At present, to locate the phone number of the closest store to a mobile telephone user, the user must otherwise consult a hard copy directory, such as a telephone book. For drivers using cell telephones in automobiles, it is difficult and dangerous for those drivers to consult a phone book while driving or to pull over to consult a phone book. Thus, the need exists for the automatic method of the present invention. Summary of the Invention
This invention is for a system and method of providing an automatic directory service for a mobile telecommunications unit based on the geographic location of the mobile unit. A user of the mobile unit places a telephone call to a desired service/goods provider using a wireless telecommunications unit. The call first accesses a wireless switch system and is then sent on to a service platform. The message to the service platform includes the geographic location of the mobile unit. The service platform then provides a lookup in a database, using the geographic location information provided, and either sends to the mobile unit the telephone number of the facility located geographically in closest proximity to the mobile unit, or, automatically connects the mobile unit to the closest geographical facility. Brief Description of the Drawings
FIG. 1 schematically illustrates an embodiment of the method and system of the present invention.
Detailed Description of the Preferred Embodiments
Referring to FIG. 1, the system and method of the present invention is schematically illustrated. The directory system 10 includes various components. In general, a remote mobile telecommunications unit 20, typically a wireless telephone, which could also be a computer or other device capable of wireless telecommunications, initiates a telecommunications message, or telephone call, to a desired service/goods provider (not shown) for the facility in closest proximity to the mobile unit 20, or for the nearest facility that services the geographic area where the mobile unit 20 is located, where the desired service/goods provider has more than one facility at more than one geographic location. The user of the mobile unit 20 does not know the geographic location of the nearest facility of the service/goods provider, such as a Home Depot, Pizza Hut, or other large chain or provider of services/goods, but does know a specific information number to call which will place the user of the mobile unit 20 in contact with the facility of the desired service/goods provider closest geographically to the mobile unit 20.
Once the telephone message is initiated by the mobile unit 20, the message is received by a wireless serving switch 16 which in turn passes the message to a service platform 18. The wireless switch 16 first passes the message to a service platform 18 using an established standard communications protocol such as CTIA IS-41 or ITU GSM MAP. The telecommunications message 24 between the mobile unit 20 and wireless serving switch 16 is typically in AMPS protocol or GSM.
The IS-41 standard typically includes an origination request (ORREQ) from the wireless serving switch 16 to the service platform 18. Within the ORREQ is typically various information, including a parameter (PARM) which contains the geographic location of the mobile unit 20. The service platform 18 replies with an ORREQ response to wireless serving switch 16. In the response, is information representing the phone number of the facility for the service/goods provider which is located geographically closest to the geographic location of the mobile unit 20, or which services the geographic area in which mobile unit 20 is located. The service platform 18 determines this phone number by performing a lookup in a database which contains telephone numbers of each facility for a typical service/goods provider, including its geographic location. A match is then made between the geographic location of the mobile unit 20 and the facility of the service/goods provider in closest proximity to the mobile unit 20, or between the geographic location of the mobile unit 20 and the facility of the service/goods provider which services the geographic area where the mobile unit 20 is located. At this point, one of two operations may transpire; 1) either the information containing the telephone number of the closest geographic facility, or facility servicing the area of the mobile unit 20, is provided through the wireless serving switch 16 back to the mobile unit 20, or, 2) the mobile unit 20 is connected by the wireless serving switch 16 through a public switching telephone network (PSTN) 14 to a terminator telecommunications unit 12, representing the facility of the desired service/goods provider located closest geographically to the mobile unit 20, or which services the geographic area of the mobile unit 20.
In another embodiment of this invention, the user of the mobile unit 20 must input an access code, or other type of authorization data, prior to the directory service function being implemented for the mobile unit 20 user. §.
The geographic position of the mobile unit 20 may be determined by a geographic location determination device 26 in various ways. In one instance, a space based satellite, such as a GPS satellite platform, or other space-based platform, which performs geographic placement functions, may be used to provide information regarding the geographic location of the mobile unit 20. In another embodiment, the mobile unit 20 itself may provide its own geographic location. In a further embodiment, a triangulation calculation is performed by a geographic location device, or a distance delay calculation is performed by a similar device to similarly determine the geographic location of the mobile unit 20. Alternatively, signal strength readings can be taken from a plurality of antenna where individual antenna are located in separate geographic "cells." The location of mobile unit 20 would be determined to be within the cell whose antenna detects the strongest signal from the mobile unit 20. This method of geographic locating would not be as accurate as the GPS method described above. Any of these geographic location methods may provide geographic location information to the wireless serving switch 16, which in turn, provides, in a PARM, the geographic information concerning mobile unit 20 to service platform 18. These embodiments and examples described above are illustrative of various embodiments of the system and method of the present invention. Those of skill in the art may recognize that other embodiments are encompassed within the scope of the claims set forth herein.
