Abstract
A home migration host position control device includes an address post processing unit that is capable of receiving an address post message from the mobile node when it migrates to a different network and is assigned a new temporary address. A home migration host list hold unit can store address information that correlates the temporary address with a home address that is contained in the address post message. A packet transfer unit that can, upon receiving a packet that is destined for the home address of the mobile node, transfer a capsulated packet that is generated by attaching to the received packet a header that indicates a destination address by a temporary address that is correlated with a home address according to address information that is stored in the home migration host list hold unit. The packet transfer unit when it receives from the mobile node a packet to which a header indicates a source address by a temporary address, can transfer a non-capsulated data packet that can be generated by removing the header from the received packet.
