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 at a home location register belonging to the terrestrial mobile communications system, wherein such registration includes location information about the mobile station; and
concurrently registering the mobile station at a home location register belonging to the satellite mobile communications system, responsive to the registration of the mobile station with the terrestrial mobile communications system, wherein such registration also includes location information about the mobile station; and
maintaining synchronization between location information about the mobile station at the said location registers.

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.
