Mobile communications service system, mobile communications service method, authentication apparatus, and home agent apparatus

摘要

In a mobile communications service system, various value-added services can be provided for each mobile node. A mobile node transmits a registration request to a foreign agent. The foreign agent transfers a Mobile request message to an authentication process server home agent (AAAH) through an authentication process server foreign agent (AAAF). The AAAH extracts from a service control database a service profile that identifies the value-added services to be supplied to the mobile node. The service profile is distributed to a home agent using a Home agent registration request message, and to a foreign agent using a mobile request message. The home agent and the foreign agent provide services according to the distributed service profiles.
