Abstract

L'invention concerne un procédé et un appareil de gestion de session, lesquels s'appliquent à un réseau mobile. Le procédé comprend les étapes consistant à : déterminer un mode d'enregistrement d'un terminal envoyant une demande d'établissement de session ou une capacité d'interfonctionnement prise en charge par un dispositif côté réseau ; et lorsque le mode d'enregistrement est un mode d'enregistrement unique ou lorsque le dispositif côté réseau prend en charge la capacité d'interfonctionnement, déterminer l'achèvement du mappage de paramètres de QoS entre différents systèmes lorsqu'une connexion de session est créée pour le terminal. La présente invention résout les problèmes techniques de l'état de la technique selon lesquels un SMF ne peut pas déterminer si un mappage de QoS doit être effectué lorsqu'un terminal établit une connexion de session dans un réseau mobile, et un processus de signalisation inutile sera provoqué pour un terminal à mode d'enregistrement double si le SMF effectue toujours un mappage de QoS.
