Method for maintaining direct device-to-device communication in wireless access system supporting device-to-device communication and apparatus for supporting same

A method for maintaining device-to-device (D2D) direct communication in a wireless access system that supports D2D direct communication, the method performed by a first base station and comprising:

• transmitting resource information on resources used for the D2D direct communication to a second base station;
• receiving resource allocation information which is newly allocated for the D2D direct communication from a second cell controlled by the second base station, from the second base station;
• and
• transmitting the resource allocation information to a first device,
• wherein the resource allocation information is transmitted to a second device which performs handover to the second base station, through an existing D2D link where D2D direct communication is performed between devices.

A second device for maintaining device-to-device (D2D) direct communication in a wireless access system that supports D2D direct communication, the second device comprising:

• a receiver;
• and
• a processor configured to maintain the D2D direct communication,
• wherein the second device moves to a second base station of a target cell and receives from a first device of a serving cell resource allocation information on a newly allocated resource region for the D2D direct communication in the target cell, through the receiver, and
• the resource allocation information is received through an existing D2D link, which is configured for D2D direct communication between the second device and the first device.
