METHOD AND APPARATUS FOR PROVIDING FLOW MOBILITY IN RADIO ACCESS SYSTEM SUPPORTING MULTI-RAT

摘要

A method for transreceiving data, according to one embodiment disclosed in the present invention, is a method for a terminal transreceiving data in a radio access system that supports RAT with a first base station that supports a first RAT and a second base station that supports a second RAT, and comprises the following steps: adding a first service flow through a dynamic service process with the first base station; receiving from the first base station a second system command message for directing connection with the second base station, wherein the second system command message includes either disconnection time information which expresses disconnection time from the first service flow or action time information which expresses the beginning of connection to the first service flow; disconnecting from the first base station and the first service flow, according to the disconnection time information; and transreceiving data pertaining to the first service flow with the second base station.
