Abstract

La présente invention concerne un procédé, un système et un dispositif pour commuter entre des systèmes de réseaux de communication sans fil dans le domaine des communications. Le procédé comprend les étapes suivantes : l'unité de réseau d'accès/fonction de contrôle de paquets AN/PCF simplifiée dans le réseau d'accès cible reçoit le message de demande de commutation du terminal, sélectionne l'AN cible sur la base dudit message de demande de commutation et ensuite transmet le message de demande de transfert de session à l'AN cible sélectionné ; ladite AN/PCF simplifiée reçoit le message de réponse de transfert de session dudit AN cible et ordonne audit terminal d'accéder audit AN cible. Le système comprend une unité de réseau d'accès/fonction de contrôle de paquets AN/PCF simplifiée et un AN cible. L'AN/PCF simplifiée comprend un module de réception et un module de traitement. En cas de décision de commuter d'un réseau UMB à un réseau HRPD, la présente invention peut raccourcir le délai total de commutation, garantir la continuité de l'activité de l'utilisateur et réduire l'interruption des activités de l'utilisateur de façon à donner une meilleure expérience à l'utilisateur en supposant que l'AT a réussi la pré-configuration du HRPD et de la session PPP.
