Abstract

A location reporting paging communication system comprising space satellites, ground stations and a remote receiving unit adapted to resolve a global position from signals transmitted from a communication transmitter. The subscriber in possession of the remote receiving unit updates the paging network with global positioning information. A caller paging a subscriber in possession of the remote receiving unit may request the global location of the remote receiving unit. The paging network could divulge or block such information from a caller depending on the requirements of the subscriber.

Claims

1. A method for updating a communication system with the location information of a mobile remote unit associated with said system:

(a) receiving a request to provide the location information of the mobile remote unit to an authorized resource and verifying when the mobile remote unit last provided its location information to said system;

(b) determining that the location of said mobile remote unit has not been established within said system for a time after said verification of (a);

(c) requesting that the location of said mobile remote unit be established within said system;

(d) establishing the location of the mobile remote unit;

(e) updating said system with the location of said mobile remote unit.

2. The method of claim 1 wherein the technique of determination during step (b) further comprises:

(i) maintaining a time stamp of when the location of said mobile remote unit was last updated within said system;

(ii) using said time stamp to verify that a predetermined time interval has passed since the location of said mobile remote unit was last updated within said system and returning the result of the verification to said system.

3. A method for updating a communication system with the location information of a mobile remote unit associated with the system:

(a) establishing the location of the mobile remote unit;

(b) providing the location information of said mobile remote unit to said mobile remote unit;

(c) comparing said location information with known geographical areas for the mobile remote unit;

(d) generating a sensory signal if the comparison of step (c) is negative and updating said system with the current location information of said mobile remote unit and;

(e) adding one or more geographic areas corresponding to said current location information to said known geographical areas.
