Title
(EN) LOCATION MANAGEMENT FOR SATELLITE SYSTEMS
(FR) GESTION DE LOCALISATION POUR SYSTÈMES SATELLITES
Abstract
(EN)
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.

La présente invention concerne des procédés, des systèmes et un appareil, comprenant des supports lisibles par ordinateur, de gestion de localisation pour des systèmes satellites. Dans certains modes de réalisation, un contrôleur d'un système de réseau satellite reçoit des données de localisation en provenance d'un terminal utilisateur et enregistre le terminal utilisateur dans une zone de mobilité avec un réseau central. Le contrôleur met à jour un mappage entre des faisceaux satellites et des zones de mobilité tandis que les faisceaux satellites se déplacent le long du sol par rapport aux zones de mobilité, puis utilise le mappage mis à jour pour communiquer avec le terminal utilisateur à l'aide d'un faisceau satellite approprié. Dans certains modes de réalisation, un contrôleur d'un système de réseau satellite détermine un mappage de faisceaux satellites en direction de zones de mobilité, et diffuse, pour chacun de multiples faisceaux satellite, un message indiquant (i) un ensemble de zones de mobilité qui sont au moins partiellement couvertes par le faisceau satellite et (ii) une indication des limites des zones de mobilité dans l'ensemble de zones de mobilité.
