Location detection system

Abstract

To increase the accuracy by which the location of an object can be determined, the present invention combines the accuracy of a GPS receiver (54) with a two-way paging system (68). A two-way pager (56) receives information indicative of the position of a GPS receiver (54) and transmits the information on a reverse channel to a paging service (68). The information is forwarded to a location determination service (64) that, if possible, converts the information into a location of the object and is provided to a requestor. In one embodiment of the invention, the requestor is a cellular call processor (18) and the object is a cellular telephone (50). The location information is used by the cellular call processor (62) to direct an emergency call to the appropriate emergency agency (80, 82) as well as to provide emergency personnel with a map showing the location of the caller.
