Abstract

L'invention porte sur un procédé et un système de traitement de connexion à un réseau de données par paquets (PDN), un dispositif de point d'ancrage et un équipement utilisateur (UE). Le procédé comprend les opérations suivantes : lorsqu'un équipement utilisateur lance une procédure d'établissement d'une seconde connexion à un réseau de données par paquets, un dispositif de point d'ancrage détermine si le nom de point d'accès (APN) de la seconde connexion à un réseau de données par paquets est le même que celui d'une première connexion à un réseau de données par paquets qui a été établie par l'équipement utilisateur, la seconde connexion à un réseau de données par paquets étant une connexion de réseau de données par paquets établie par l'équipement utilisateur par l'intermédiaire d'un réseau d'accès non 3GPP, et la première connexion à un réseau de données par paquets étant une connexion à un réseau de données par paquets établie par l'équipement utilisateur par l'intermédiaire d'un réseau d'accès 3GPP ; et s'ils sont les mêmes, le dispositif de point d'ancrage envoie des premières informations d'indication à l'équipement utilisateur, les premières informations d'indication étant utilisées pour indiquer que l'équipement utilisateur diffère le lancement de la procédure d'établissement de la première connexion à un réseau de données par paquets après que la première connexion à un réseau de données par paquets a été interrompue. Le procédé peut atténuer la génération de phénomènes de ping-pong et économiser efficacement des ressources de réseau sans fil.
