METHOD FOR PERFORMING HANDOVER IN WIRELESS ACCESS SYSTEM FOR SUPPORTING COMMUNICATION BETWEEN DEVICES AND APPARATUS FOR SUPPORTING SAME

摘要

The present invention provides a ceaseless communication method between devices in a wireless access system for supporting communication between the devices, a method for switching the communication to a cellular network, and an apparatus for supporting the same. A method for performing a handover to the cellular network in the wireless access system for supporting the direct communication between the devices according to one embodiment of the present invention, includes the steps of: detecting the generation of a handover condition to the cellular network in a first device for performing the direction communication between the devices; transmitting a message for requesting a bandwidth for the cellular network to a base station; receiving a bandwidth response message including the bandwidth allocation information for the bandwidth allocated to the first device as a response to a bandwidth request from the base station; and enabling the first device to transmit data through the base station and the cellular network on the basis of the bandwidth allocation information for the bandwidth.
