Abstract

La présente invention concerne un procédé permettant de suivre un utilisateur au cours du processus de commutation. Selon le procédé, une unité de gestion de mobilité (MME) obtient des informations de suivi d'utilisateur d'une MME source (301), puis envoie ces informations de suivi d'utilisateur à un noeud B évolué cible (eNB) (302); l'eNB évolué cible suit l'utilisateur à l'aide des informations de suivi d'utilisateur (303). Selon l'invention, la MME cible obtient les informations de suivi d'utilisateur de la MME source, puis les envoie au eNB cible et suit ainsi un équipement utilisateur (UE) dans un réseau cible, de manière à résoudre le problème consistant à ne pas pouvoir suivre un utilisateur dans le réseau cible au cours du processus de commutation. En correspondance avec le procédé susmentionné, l'invention concerne également un dispositif et un système permettant de suivre un utilisateur au cours du processus de commutation.
