PURPOSE: An FA(Foreign Agent) device for supporting a mobile IP(Internet Protocol) service in an asynchronous mobile communication system and a mobile IP service method using the same are provided to support the mobile IP service about an asynchronous mobile communication network and support several new standards. CONSTITUTION: A mobile IP service registration unit(206) performs a signal process for a mobile IP. A GGSN(Gateway GPRS(General Packet Radio Service) Support Node) interface unit(201) is connected to the mobile IP service registration unit(206) and is interfaced to an asynchronous mobile communication network. A diameter protocol processing unit(204) transmits and receives data with an authentication and billing server(132) of a mobile IP network by an authentication protocol. An authentication unit(202) connects to the mobile IP service registration unit(206) and the diameter protocol processing unit(204), and performs an authentication function of an FA unit by the control of the mobile IP service registration unit(206). A billing processing unit(203) connects to the mobile IP service registration unit(206) and the diameter protocol processing unit(204), gathers billing information about a packet which passes an FA(131) by the control of the mobile IP service registration unit(206), and transmits gathered billing information. A packet routing and tunneling control unit(205) designates a routing table about a mobile node(11) and performs a setup/release function of a tunnel by the control of the mobile IP service registration unit(206).
