Abstract

La présente invention appartient au domaine technique des communications réseau. La présente invention concerne un procédé, un dispositif et un système d'établissement de réseau public de données (PDN), résolvant le problème du gaspillage de ressources système dans l'état de la technique. Le procédé est appliqué à l'architecture de gestion de mobilité distribuée (DMM) ou à une architecture coexistante de la DMM et à un système paquet évolué (EPS) ; lorsqu'il n'y a pas d'interface entre une entité de gestion de mobilité (MME) et chaque passerelle, le procédé comprend les étapes consistant à : recevoir un message de demande de service d'un équipement utilisateur (UE) et envoyer le message de demande de service à la MME, le message de demande de service contenant une identité de service correspondant au service à assurer par l'UE ; recevoir de la MME des informations connexes pour rétablir un PDN, les informations connexes contenant l'adresse d'une première passerelle ; obtenir l'adresse d'une seconde passerelle d'une station de base dans laquelle l'UE est actuellement situé ; et établir un canal de la première passerelle à la seconde passerelle. La présente invention s'applique au rétablissement de PDN.
