METHOD AND DEVICE FOR TRANSMITTING/RECEIVING DATA IN WIRELESS ACCESS SYSTEM SUPPORTING MULTI-RADIO ACCESS TECHNOLOGY

摘要

The present invention relates to a method by which a terminal transmits/receives data to/from a first base station supporting a first wireless access technology and a second base station supporting a second wireless access technology in a wireless access system supporting multi-radio access technology (multi-RAT), the method comprising: a step for executing an initial network entry process with the first base station; a step for executing a multi-RAT capability negotiation process with the first base station to exchange information needed to access the second base station; a step for executing a scanning process on at least one second base station included in the coverage of the first base station, based on the information received from the first base station through the multi-RAT capability negotiation process; a step for executing an access process with one of the second base stations from said at least one second base station; and a step for simultaneously transmitting/receiving data with the first base station and the second base station accessed through the access process, wherein the step for executing the access process includes: a step for receiving a second system access command message that commands access to the one of the second base stations from the first base station; and a step for accessing the one of the second base stations based on the second system access command message received.
