Abstract

L'invention concerne un procédé pour le couplage et la coordination d'une première gestion de mobilité IP d'un premier réseau (RAN) avec une deuxième gestion de mobilité IP d'un deuxième réseau (central). A cet effet, une instance (CN-VMH1) est prévue entre le premier réseau et le deuxième réseau, ladite instance pouvant participer aussi bien à la première gestion de mobilité IP du premier réseau qu'à la deuxième gestion de mobilité IP du deuxième réseau. Dans un mode de réalisation de l'invention, l'utilisateur (UE) continue à se déplacer, une nouvelle instance (CN-VMH2) est créée sur une autre passerelle. Cette nouvelle instance est enregistrée en tant que noeud correspondant dans la gestion de mobilité de cette autre passerelle, et s'enregistre en tant qu'hôte mobile virtuel dans le premier réseau (RAN) et en tant qu'hôte mobile virtuel (VMH*2) dans le deuxième réseau (central). L'information d'état de liaison est transférée de l'instance de la passerelle d'origine (CN-VMH1) à la nouvelle instance. L'instance de la passerelle d'origine est ensuite effacée. L'invention concerne en outre une structure de réseau correspondante.
