Abstract
The home agent system of the present invention performs not only the process of managing the position information of a mobile node, but also the process of transferring a packet to the mobile node using the position information. The home agent system comprises one or more position processing devices processing the position information notification packet transmitted from the mobile node and acquiring the position information of the mobile node and a transfer processing device transferring the packet addressed to the mobile node, which is connected to one or more position processing devices. The transfer processing device has a position information management table which stores the position information acquired by the position processing device in association with the home address of the mobile node and a transfer unit transferring the packet addressed to the mobile node using the stored position information.
