Abstract

L'invention concerne un procédé et équipement d'installation de connexion: Ledit procédé consiste notamment en ce : qu'une entité de gestion de mobilité (MME) choisit une passerelle locale ou une passerelle de réseau central selon des paramètres (S302), les paramètres étant l'un ou l'autre: identificateur de l'élément côté réseau sans fil, identificateur de groupe abonné fermé (CSG ID) de CSG, identificateur d'emplacement, identificateur de zone de suivi (TAI), informations d'abonnement, informations configurées localement pour indiquer si l'accès au protocole Internet local est ou non autorisé, et le type de connexion; ladite MME établit une connexion d'accès IP local par le biais de ladite passerelle locale, ou établit une connexion de réseau central par le biais de ladite passerelle de réseau central (S304). Selon l'invention MME choisit une passerelle locale selon des paramètres, de façon qu'elle puisse établir une connexion d'accès IP local par le biais de la passerelle locale choisie, et mettre ainsi en oeuvre efficacement l'accès IP local.
