Claim Text:
1. A method of performing communication between a mobile station and a base station in a wireless access system supporting a multi-radio access technology (RAT), the method comprising: performing an access procedure between a first base station supporting a cellular RAT and a second base station supporting a local area network RAT; receiving, by the second base station from the first base station through a first radio channel, first control information related to transmission of an identification signal (IDS) used to detect, by the mobile station, the second base station, wherein the first control information includes all of a downlink resource region for IDS transmission, an IDS transmission type, and IDS transmit power information; and transmitting the IDS, by the second base station, to the mobile station through the first radio channel based on the received first control information, wherein the first radio channel is a radio channel corresponding to the first base station, wherein the first radio channel is a superframe, wherein the IDS is transmitted in every single superframe for a specific number of consecutive superframes, wherein information related to the specific number of consecutive superframes is broadcasted or unicasted to the first base station, wherein, after the transmission of the IDS, a measurement result of the IDS is reported from the mobile station to the first base station, wherein, after the reporting of the measurement result of the IDS, second control information required to perform a handover is transmitted from the first base station to the mobile station, and wherein the second control information includes all of a service set identifier (SSID) of the second base station, an Internet protocol (IP) address of the second base station, channel information of the second base station, transmit power information of the second base station, and a disconnection time with respect to the first base station.
