ABSTRACT:
A satellite telecommunications system that is operative in conjunction with an existing terrestrial telecommunications system. The satellite telecommunications system includes at least one satellite in earth orbit, at least one terrestrial communications gateway for coupling the at least one satellite to the terrestrial telecommunications system, a plurality of satellite telecommunications system subscriber transceivers operative for conducting communications through the at least one satellite with subscribers of the terrestrial telecommunications system, and a terrestrial network coordinating gateway (NCG) in communication with the at least one satellite. The NCG includes a satellite receiver for receiving access requests from individual ones of the plurality of subscriber transceivers and a controller for assigning satellite channels on behalf of the subscriber transceivers and for selecting terrestrial communications gateways to create call set-up links on behalf of the subscriber transceivers. The NCG further logs-in roaming subscriber transceivers.
