A method for scanning for a base station (BS) of a second radio access technology (RAT) by a user equipment (UE) connected to a first RAT in a multi-RAT environment includes receiving information about one or more BSs of the second RAT adjacent to the UE, from an interworking entity (IWE) of the first RAT which manages interworking between the first RAT and the second RAT, and transmitting an awake request message to a specific BS among the BSs of the second RAT in a listening interval of the specific BS to which the UE desires to access, if a status of the specific BS is an idle mode, wherein listening interval information is included in the received information about the BSs of the second RAT.
