Abstract
A telecommunications system and method for managing the eligibility of access to a satellite-based network by mobile originated and mobile terminated calls by including, for example, within the tables that the Terrestrial Network Manager (TNM) consults, information regarding areas with no allowed service area and areas with restricted service. After the location and the International Mobility Subscriber Identity (IMSI) of the calling and called party are determined, the tables are consulted and a determination is made regarding whether the calling or called party should be excluded from the satellite/beam selection. Advantageously, the systems and methods of the present invention are not dependent on accurate location information being stored in the MSC/VLR.
