SYSTEMS AND METHODS FOR MOBILITY MANAGEMENT IN OVERLAID MOBILE COMMUNICATIONS SYSTEMS
First Claim
1. A method of coordinating communications of a mobile station with a satellite mobile communications system and a terrestrial mobile communications system, the method comprising:
- registering the mobile station for service at a terrestrial mobile communications system, wherein such registration for service includes registering location information about the mobile station at a home location register belonging to the terrestrial mobile communications system;
authenticating the mobile station with an authentication center belonging to the terrestrial mobile communications system;
concurrently registering the mobile station for service at the satellite mobile communications system, responsive to the registration of the mobile station for service with the terrestrial mobile communications system, wherein such registration also includes registering location information about the mobile station at a home location register belonging to the satellite mobile communications system;
concurrently authenticating the mobile station with an authentication center belonging to the satellite mobile communications system;
maintaining synchronization between location information about the mobile station at the location registers, as the location information changes due to movement of the mobile station so that the mobile station is concurrently enabled to communicate over each of the terrestrial mobile communications system and the satellite mobile communications system;
switching the mobile station from communicating with the terrestrial mobile communications system to being enabled to communicate with the satellite communications system using the location information at the home location register belonging to the satellite mobile communications system that was maintained synchronized with the location information at the home location register belonging to the terrestrial mobile communications system and without performing a location update of the home location register belonging to the satellite mobile communications system, and using the authentication of the mobile station with the authentication center belonging to the satellite mobile communications system that was concurrently authenticated, without retrieving additional authentication data.

Abstract
Communications of a mobile station with a satellite mobile communications system and a terrestrial mobile communications system are coordinated. The mobile station is registered with the terrestrial mobile communications system and, responsive to the registration of the mobile station with the terrestrial mobile communications system, the mobile station is concurrently registered with the satellite mobile communications system. The concurrent registration may include implicitly registering the mobile station with the satellite mobile communications system, e.g., by storing information identifying the mobile station may be stored in a location register of the satellite mobile communications system responsive to the registration of the mobile station with the terrestrial mobile communications system, and maintaining synchronization between the two registrations. Authentication tokens may be pre-generated for quick re-registration with a satellite mobile communications system.
