Abstract

L'invention concerne un procédé et un dispositif d'accès au réseau, qui sont appliqués à un OWA. Le procédé comprend les étapes suivantes : un dispositif sur le côté réseau reçoit des informations de déclenchement de transfert envoyées par un premier nœud de réseau correspondant à un premier réseau, les informations de déclenchement de transfert étant utilisées pour déclencher la détermination de l'opportunité de transférer le réseau d'accès pour un UE connecté par le premier nœud de réseau ; et lorsque le besoin de transférer l'UE à un second réseau est déterminé, d'après les informations de déclenchement de transfert, le dispositif sur le côté réseau commande à un second nœud de réseau correspondant au second réseau d'établir une connexion avec l'UE, les types du premier réseau et du second réseau étant différents. Le procédé et le dispositif décrits dans la présente invention résolvent le problème lié, dans l'état de la technique, au gaspillage significatif de ressources de puissance et de signalisation lorsqu'un transfert de réseau d'accès est exécuté pour un UE.
