Abstract

A technology to secure secrecy of the position of a user of a target mobile node of handover and to use resources effectively by preventing double reservation. In this technology, MN (2701) before handover and MN (2721) after handover use different session IDs. In order to link the different session IDs with each other, synchronization information for modifying group information indicating the groups which the MNs (2701, 2721) and SANEs (2703, 2705, 2707, 2723) which establish the paths of the MNs (2701, 2721) belong to in synchronization each time handover occurs is set up between the MNs (2701, 2721) and a group server (2731) to destroy the resources of old paths.
