Abstract

L'invention concerne un procédé et un dispositif de transfert. Dans les modes de réalisation de la présente invention, des informations concernant une cellule de desserte d'un deuxième dispositif d'accès au réseau d'un UE sont obtenues par un premier dispositif d'accès au réseau, le premier dispositif d'accès au réseau et le deuxième dispositif d'accès au réseau appartiennent à des systèmes différents de communications sans fil, de sorte que le premier dispositif d'accès au réseau peut transférer l'UE à la cellule de desserte dépendant du deuxième dispositif d'accès au réseau en fonction des informations concernant la cellule de desserte, ce qui permet de résoudre le problème d'échec d'un transfert dans l'état antérieur de la technique dû au fait qu'une cellule de destination vers laquelle un système hétérogène effectue un transfert n'est pas la cellule de desserte de l'UE dans le système hétérogène, accroissant ainsi la fiabilité des transferts. De plus, en utilisant la solution technique décrite dans la présente invention, il n'est pas nécessaire que l'UE mesure une interface radio d'un système hétérogène, ce qui permet d'éviter une mesure non valide de l'interface radio d'un système hétérogène effectuée par l'UE et l'accroissement de la consommation énergétique de l'UE.
