Abstract

L'invention concerne un procédé, un appareil et un système de recherche dans un réseau. Une passerelle de plan utilisateur (GW-U) comprend une table d'acheminement par localisateur. Le procédé comprend les étapes suivantes : lorsqu'un équipement utilisateur (UE) connecté au réseau passe à l'état de veille, la GW-U acquiert un identifiant (ID) de l'UE envoyé par une passerelle de plan de commande (GW-C), un ID d'un ensemble d'emplacements correspondant à la zone dans laquelle se trouve l'UE et un message de recherche ; apparie des informations de localisation concernant au moins un nœud B évolué (eNB) à partir de la table de transmission d'emplacement selon l'ID de l'ensemble d'emplacement ; et lorsque la réception d'un paquet pour l'UE est confirmée, envoie audit eNB l'identifiant de l'UE et le message de recherche. Ainsi, on peut observer que lorsqu'une GW-U reçoit un paquet pour un UE passant à l'état de veille, une interaction de signalisation redondante avec une GW-C n'est plus nécessaire, et un message de recherche préalablement acquis peut être directement envoyé à l'eNB prédéterminé lié à l'emplacement de l'UE, ce qui permet d'économiser le temps de reconnexion de l'UE et d'une station de base, et d'améliorer l'expérience utilisateur.
