Abstract
Methods, systems, and apparatus, including computer-readable media, for location management for satellite systems. In some implementations, a controller of a satellite network system receives location data from a user terminal and registers the user terminal in a mobility area with a core network. The controller updates a mapping between satellite beams and mobility areas as the satellite beams move along the ground with respect to the mobility areas, then uses the updated mapping to communicate with the user terminal using an appropriate satellite beam. In some implementations, a controller of a satellite network system determines a mapping of satellite beams to mobility areas, and broadcasts, for each of multiple satellite beams, a message indicating (i) a set of mobility areas that are at least partially covered by the satellite beam and (ii) an indication of boundaries of the mobility areas in the set of mobility areas.
