METHOD AND SYSTEM FOR POSITIONING MOBILE STATION IN HANDOVER PROCEDURE

摘要

PURPOSE: A method and a system for arranging a terminal in a handover process is provided to improve efficiency of the handover of a user terminal by reducing influence of the handover process through a core network. CONSTITUTION: UE(User Equipment) transmits an NAS(Non-Access Stratum) message to HeNB(Home Evolved NodeB)(501). The HeNB transmits the NAS message to an HeNB GW(Gateway) through an initial UE message(502). An authentication-security process is processed(503). An MME(Mobility Management Entity) determines that a down link node is the HeNB GW(504). The MME transmits a initial context establish request message to the HeNB GW(505). The HeNB GW stores an NH(Next Hop), a KASME(Key Access Safety Management Entity), and the KeNB(506). The HeNB GW transmits the initial context establish request message to the HeNB(507). The HeNB establishes a radio bearer between the UE and the HeNB(508). The HeNB transmits an initial context establishment response message to the HeNB GW(509). The HeNB GW transmits the initial context establishment response message to the MME(510).
