Abstract

La présente invention concerne un procédé et un appareil de détermination de liste de zones d'enregistrement. Le procédé comprend les étapes suivantes : un élément de réseau AMF reçoit N identifiants de zone de service, chacun des identifiants de zone de service correspondant à une zone de service d'un élément de réseau UPF fournissant un service pour un terminal, les N identifiants de zone de service étant envoyés par M éléments de réseau SMF, N et M étant des entiers positifs supérieurs à 0 ; et l'élément de réseau AMF détermine une liste de zones d'enregistrement selon une corrélation entre l'identifiant de zone de service et la zone de service de l'élément de réseau UPF fournissant un service pour le terminal, et l'élément de réseau AMF envoie la liste de zones d'enregistrement au terminal.
