(Steps S 308, S 309, and S 310), but in the second embodiment, the address allocating unit 25 assigns the home address assigned to the corresponding authentication ID. It is checked whether or not the number is within the quantity (step S1308). If there is still free space, the address of the mobile router making the allocation request is checked by referring to the address management table 24, and It is determined whether or not the mobile router has already been authenticated (step S1309).
- the address allocating unit 25 transmits a new home route to the new mobile route described in the target address of the received address allocation request message. Assign an address. That is, in the address management table shown in FIG. 16, the address allocating unit 25 sets the home address 601 and the temporary address 603 at the position having the same authentication ID as the first mobile router 1001. And, the flag 605 is additionally registered. The flag at this time is "assigned". Then, the address allocating unit 25 instructs the packet generating unit 23 to generate an address allocation permission message in which the command 400 3 is “address allocation”. (Step S1 3 1 3).
- the packet generator 23 generates an address assignment permission message in the format shown in FIG. 14C. This message differs from that shown in FIG. 4B in that it has the target address 1442.
- the packet generator 23 sets the command 4 13 as “address allocation” and sets the allocated home address 4 15 and the internal prefix 4 16 in the address allocation permission message 4 10.
- the address of the internal network of the second mobile router that has been received is set as the target address 1401 (step S1314).
- Subsequent operations are the same as the processes (steps S313 to S318) in the first embodiment.
- step S1205 the operation when the first mobile router 1001 receives an address assignment permission message from the location management server 2 will be described with reference to FIG. If a response message is not received within a predetermined time in the reception waiting, the processing is terminated (step S1205).
- the message analyzing unit 60 notifies the proxy requesting unit 91.
- the proxy request unit 91 checks whether or not the target address 1441 is for the second transfer (step S1206), and if it is not for the second transfer. Terminates the processing (step S12204).
- the proxy request unit 91 instructs the packet generation unit 54 to transmit an address assignment permission message to the second mobile station.
