Abstract

La présente invention porte sur un procédé de mise à jour de tunnel dans un système de communication prenant en charge un accès sous protocole Internet (IP) local. Le procédé comprend les étapes suivantes : un terminal utilisateur étant en état de veille, lorsqu'un composant de gestion de mobilité reçoit une notification de données de liaison descendante provenant d'une unité de tampon de données et le terminal utilisateur a déjà activé un accès IP local, le composant de gestion de mobilité déclenche la mise à jour des tunnels de transmission d'accès IP local entre un élément de réseau côté sans fil et l'unité de tampon de données, et entre l'élément de réseau côté sans fil et la passerelle d'accès local; ou, selon la source des données de liaison descendante, la mise à jour de tunnels, qui permettent à l'IP local d'accéder à une transmission de données de tampon de liaison descendante, est déclenchée entre l'élément de réseau côté sans fil et la passerelle d'accès local, et sélectivement entre l'élément de réseau côté sans fil et l'unité de tampon de données. La présente invention porte également sur un système mettant en œuvre ce procédé. Les solutions techniques de la présente invention sont simples et pratiques.
