1. A method of geofencing for satellite communication performed by a user equipment (UE), the method comprising:
obtaining a first region file comprising a plurality of regions, wherein each region of the plurality of regions is represented by one or more geo-polygons, wherein each region of the plurality of regions corresponds to a respective unique region identifier, and wherein the plurality of regions corresponds to a first set of region identifiers;
obtaining a first restriction status file comprising restriction status information regarding each region of the plurality of regions, wherein the first restriction status file is indicative of, for each region of the plurality of regions, a restriction status of one or more satellite-related services with respect to the UE within the region represented by the one or more geo-polygons;
receiving, from a server, a second restriction status file comprising a second set of region identifiers and corresponding restriction status information;
determining a difference between the first set of region identifiers and the second set of region identifiers; and
updating the first region file, the first restriction status file, or both based on the difference.
