Patent ID: 11589330

Abstract:
Satellite access to a PLMN with a Fifth Generation (5G) core network (5GCN) is supported by a serving satellite NodeB (gNB). The gNB determines or verifies the country in which a user equipment (UE) is located to ensure that the UE is located in the same country as the PLMN. The gNB may determine the country of the UE based on UE measurements from broadcast satellite signals and a positioning ID (PID) broadcast for each radio cell. The PID frequently changes to prevent spoofing. The gNB may use multiple UE measurements from a moving radio cell over a period of time to generate a more accurate location for the UE. The gNB may indicate to a 5GCN whether the country of the UE has been verified. The 5GCN will determine the location and country of the UE if the gNB indicates that the country is not fully verified.
