Abstract
When first mobile router, which has a MNP, generates a key which corresponds to that MNP and transmits a registration request packet including the key to home agent, home agent stores the MNP and key of the first mobile router, and sends main mobile router registration approval. When first mobile router receives this response, it distributes the MNP and key to second mobile router in moving network. Second mobile router, which receives this, transmits a registration request packet including the MNP and key to home agent, and thereby, home agent registers second mobile router as a subsidiary mobile router. By this means, it is possible to prevent illegal acquirement of a packet addressed to a moving network by use of a mobile router which shares the network prefix (MNP).
