MOBILE TERMINAL, RELAY EQUIPMENT AND MOBILE COMMUNICATION SYSTEM

摘要

A UE (10) receives a PDN ID via an attach procedure. A serving GW (20) receives address generation information and the PDN ID from a PDN-GW and stores them. When a router solicitation message containing the PDN ID is transmitted from the UE (10) to the serving GW (20), the serving GW (20) transmits a router advertisement message containing the PDN ID. The UE (10) which receives the router advertisement message generates an IP address from the router advertisement message and stores it based on the received PDN ID. The UE (10) determines the IP address in response to the communicating PDN and makes communication. Thus, a mobile communication terminal or the like capable of appropriate communication can be provided, by making correct correspondence between each network and the IP address when the terminal acquires the IP address from a plurality of networks.
