Claim Text:
1. A method for performing an inter-radio access technology (RAT) handover, the method comprising: receiving, by a user equipment (UE), wireless local area network (WLAN) access information from a base station, the WLAN access information including measurement information indicating a measurement configuration for the UE, identity information indicating an identifier of an access point (AP), and beacon information for receiving a beacon frame from the AP; receiving, by the UE, the beacon frame from the AP based on the beacon information; measuring, by the UE, a value associated with the beacon frame based on the measurement information; and performing, by the UE, initial channel access to the AP when a result of a comparison between the measurement configuration and the measured value associated with the beacon frame meets a predefined requirement for a minimum available time for inter-RAT handover, wherein the beacon information includes a beacon frame transmission time offset and operation channel information, the beacon frame transmission time offset indicating a timing of a beacon frame transmitted by the AP and the timing of a beacon frame calculated in units of time used to transmit downlink data by the BS, the operation channel information indicating an operating channel of the AP.
