  Abstract

For supporting Mobile IP service in release 99 UMTS/GPRS, network architecture has been considered in three steps. At the first step, the interface between the GGSN(Gateway GPRS Support Node) and the FA(Foreign Agent) will probably not be standardized as the GGSN/FA is considered being one integrated node or, two separated nodes. The mapping between these two is a matter of implementation. For the latter case, however, a proprietary interface has to be defined to realize it. For this purpose, a proprietary Gi interface between the GGSN and the FA is newly defined in this paper. And data traffic and signal protocol suites are proposed. A SIAM(Session Identifier Adaptation Mechanism) is also designed, which uses a MN''s state machine for managing a Gi session and a GTP(GPRS Tunneling Protocol) session identifier of GPRS for identifying a GTP session. It would enable us to implement the Gi interface with easy facility as Mobile IP signaling can be transferred over UDP and data traffic can be transferred over IP-in-IP.
