1. A method of changing association identification (AID) of a first station performing a direct communication with a second station in a wireless communication system, the method comprising:transmitting, by the first station to an access point (AP), a switch request frame for requesting a new AID when a traffic pattern of the first station changes,
wherein a group consisting of stations having a same listen interval is distinguished by the AID,
wherein a listen interval of the first station and a group, to which the first station is associated, are changed when the traffic pattern of the first station changes,
wherein the AID of the first station is updated based on the change in listen interval of the first station and the change in the group of the first station,
wherein the first station and the second station have an established direct link, and
wherein the direct link is established based on a tunneled direct link setup;
receiving, by the first station from the AP, a switch response frame containing new AID information which is newly assigned to the first station and the second station,
transmitting, by the first station, the new AID information included in the switch response frame to the second station; and
changing the AID of the first station and the second station using the received new AID information.
