Abstract: PROBLEM TO BE SOLVED: To attain a radio access method to a packet base network for realizing local movability in a sub-net with the minimum delay and traffic amounts. SOLUTION: Local movability in a sub-net can be realized by maintaining and updating routing table entry in a domain router and a base station for transferring a packet having the address of a mobile device as a destination address to the destination of the mobile device. The packet can be transmitted to the destination of the mobile device regardless of which base station the mobile device is connected with. When the mobile device is positioned in a domain outside a region, a notice address is assigned to the mobile device, and the tunneling of packet to the destination of the mobile device is operated. It is necessary for the mobile device to have one notice address for each outside domain.

Abstract: PROBLEM TO BE SOLVED: To achieve efficiency of packet distributing paths using a mobile IP. SOLUTION: Routing table entry corresponding to a mobile device in a router (including a base station having a routing function) in a single domain is communicated by using the routing of a host base. This routing table entry is established and communicated through a path setting scheme for transmitting a packet directed to the mobile device along paths originally established through the domain router and the base station. This is operated regardless of the domain base station with which the mobile device is connected. The path setting scheme can maintain an appropriate relationship between a router interface and a packet address for the routing table entry by using power source refresh and a hand-off path setting message.
