Summary:A technique of acquiring a binding ID when a mobile node performs handover is disclosed. According to the technique, when an MN (10) performs an initial startup on a Non-3GPP network (30), a AAA server (50) generates and stores the binding ID, transmits it to a proxy node (31), and transmits allocation information indicating that the proxy node is allocated the binding ID to the MN. When performing the handover to a 3GPP network (20), the MN requests the binding ID to an HA (32). The HA then requests the binding ID to the AAA server and the AAA server transmits the binding ID to the HA. The HA receives the binding ID and transmits it tothe MN. L'invention concerne une technique d'acquisition d'un identifiant de liaison lorsqu'un noed mobile effectue un transfert. Selon la technique, lorsqu'un MN (10) effectue un démarrage initial sur un réseau Non-3GPP (30) ; un serveur AAA (50) génère et stocke l'identifiant de liaison, le transmet à un noed de serveur mandataire (31) et transmet des informations d'allocation indiquant que le noed de serveur mandataire s'est vu allouer l'identifiant de liaison au MN. Lors du transfert vers un réseau 3GPP (20), le MN demande l'identifiant de liaison à un HA (32). Le HA demande ensuite l'identifiant de liaison au serveur AAA et leserveur AAA transmet l'identifiant de liaison au HA. Le HA reçoit l'identifiant de liaison et le transmet au MN.
