METHOD FOR CHANGING AID IN WIRELESS LAN SYSTEM

摘要

Disclosed is a method for changing an AID in a wireless LAN system. The method for changing an AID of a terminal by an access point comprises: a step of receiving an AID reassignment frame from the access point; a step of extracting an AID reassignment counter value from the AID reassignment frame; and a step of changing the AID of the terminal to the new AID included in the AID reassignment frame after the beacon periods of the access point indicated by the AID reassignment counter value extracted from the AID reassignment frame reception time have elapsed. Thus, a conflict between AIDs can be prevented.

1. A method of switching an association ID (AID) of a terminal, the method comprising:
receiving, by the terminal from an access point, an AID switch response frame including an AID response element, the AID response element including an AID field and an AID switch count field; and switching to a new AID after a duration specified by the AID switch count field, when an AID included in the AID field of the AID response element is not same as a current AID of the terminal, and the AID included in the AID field of the AID response element being used as the new AID, wherein the AID switch count field indicates a countdown value, in units of beacon interval, that the AP sets for the terminal to switch to the new AID, and the AID switch count field indicates the duration after which a counter that corresponds to the AID switch count field starts upon transmission of the AID response element.
