Abstract

Les modes de réalisation de la présente divulgation concernent un procédé de communication par satellite, un dispositif de communication et un support de stockage. Le procédé de communication par satellite, qui est exécuté par un premier dispositif réseau, peut consister à : sur la base d'un premier identifiant de satellite et d'un DNN fournis par un premier équipement utilisateur (UE), déterminer un premier identifiant d'accès au réseau de données (DNAI), le premier identifiant de satellite indiquant un premier satellite ; le premier satellite étant un satellite où une première fonction de station de base accessible par le premier UE est située ; et le premier DNAI étant utilisé pour identifier un service, le premier UE utilisant une fonction de plan utilisateur (UPF) portée par satellite pour effectuer une communication locale avec au moins un second UE.
