Abstract

Des modes de réalisation de la présente invention concernent un procédé et un dispositif de détermination d'une UPF sur satellite. Le procédé est appliqué à une SMF et consiste à : déterminer, sur la base d'informations d'assistance de sélection d'UPF sur satellite configurées dans des informations de configuration UPF, une UPF sur satellite qui fournit un service à une première station de base, les informations d'aide à la sélection d'UPF sur satellite comprenant des informations de station de base ou des informations de satellite, et la première station de base étant une station de base fournissant actuellement un service à un terminal cible, ou étant l'une quelconque de toutes les stations de base fournissant un service à une pluralité de terminaux cibles dans un groupe de réseau virtuel. Selon le procédé de détermination de l'UPF sur satellite décrit dans les modes de réalisation de la présente invention, la configuration d'une relation entre l'UPF et la station de base ou la configuration d'une relation entre l'UPF et un satellite est ajoutée dans les informations de configuration UPF, de telle sorte que l'UPF sélectionnée par la station de base fournissant un service au terminal cible est garantie comme étant l'UPF sur satellite capable de fournir un service à la station de base.
