Systems and methods for supporting satellite access from mobile devices to public land mobile networks

Abstract:

Access, mobility management and regulatory services are supported for satellite access to a Fifth Generation (5G) core network (5GCN). A location of a UE may be obtained by a UE or by a base station and used to determine a country in which the UE is located. The UE can then select a serving PLMN in the country of the UE which is accessible from a radio cell supported by a satellite. The UE can register with the serving PLMN and receive information from the serving PLMN concerning fixed cells and fixed tracking areas supported by the serving PLMN. If the UE attempt to register with a PLMN not in the country of the UE, a serving base station can reject the attempt and indicate the country to the UE.
