Abstract
Access, mobility management and regulatory services are supported for satellite access to a Fifth Generation (5G) core network. A coverage area, e.g., country, region, multiple countries, and international areas, are divided into fixed virtual cells having well defined geographic boundaries and fixed tracking areas. Information for the virtual cells and/or tracking areas and associated with one or more public land mobile networks (PLMNs) may be provided to a user equipment (UE). The UE may obtain its position, e.g., using a satellite positioning system, and determine the serving virtual cell or tracking area in which it is located. The UE may perform registration with a serving core network in a serving PLMN associated with the serving virtual cell or tracking area. Regulatory services, such as emergency (EM) calls, lawful interception (LI), wireless emergency alerts (WEA) may be provided based on the serving virtual cell or tracking area.
