Abstract: A communication system, in which a mobile terminal uses a data path that was generated with an ISP network by a base station in a home network to access a NW via the ISP network, includes an authentication means and connection control means in the ISP network. The base station accepts an access request from the mobile terminal and transmits information relating to the base station and the mobile terminal to the connection control means.

Based on this notification, the connection control means requests the base station to generate a data path for providing the linking service, and the base station generates the data path.

Abstract: The signaling amount for acquisition of home addresses (HoA) and handover over the radio leg is reduced in a case where a mobile node (MN) requires multiple different communication IP addresses (Home address: HoA) for respective services. An AAA server holds service identifiers of all the services provided for the mobile node (MN) and home agent (HA) information, in addition to authentication information of the mobile node (MN). The AAA server also registers, for all the services provided for the mobile node (MN), an association of home addresses (HoA) used by the mobile node (MN) for the respective communication services with IP addresses (care-of address: CoA) having information of a network in which the mobile node (MN) resides, into the home agents (HA) associated with the corresponding service identifiers.
