Abstract

La présente invention concerne un procédé et un appareil pour exécuter des procédures d'attachement dans un système d'évolution à long terme (LTE) pour loger une seule approche de tunnel. Des procédures d'activation de contexte pour le protocole de données de paquet (PDP) d'un programme de partenariat de troisième génération (3GPP) servent à allouer une adresse de protocole Internet (IP) et établir une tunnelisation entre un noeud B évolué (eNodeB) et un autre noeud, tout en permettant à plusieurs porteurs d'accès radio (RAB) d'être mis en correspondance sur un contexte PDP pour différents critères de qualité de service (QoS). Ainsi, un contexte PDP suffit pour une unité sans fil de transmission/réception (WTRU) dans un réseau de données de paquet uniques (PDN). Plusieurs contextes PDP peuvent être établis pour des critères spéciaux (par ex. services groupés) ou lorsque le WTRU se connecte à plusieurs PDN.
