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 location information of a mobile remote unit comprising steps of:

(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 communication system;

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

(c) requesting that the location information of said mobile remote unit be established after said verification of (a) within said communication system; and

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

(e) updating said communication system with the location information of said mobile remote unit;

wherein the determining of said step (b) further comprises;

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

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

2. A method according to claim 1 for updating the communication system with the location information of the mobile remote unit associated with the communication system:

(b) periodically obtaining the location information of 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 communication 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.
