The method for associating a first AP with an STA in a wireless LAN includes the steps of: a first AP receiving an association request frame from the STA; the first AP requesting authentication information on the STA from a second AP with which the STA was previously associated; the first AP receiving authentication information on the STA from the second AP, wherein the first and second AP's are linked by a distribution system, the association request frame includes identification information on the second AP, and the authentication information on the STA can include at least one of a paired main key (PMK) and a recertification main session key (rMSK). Accordingly, fast association between the STA and the AP can be achieved by a simplified authentication procedure without repeating a full authentication procedure. | 02-05-2015 |
20150078358 | METHOD AND APPARATUS FOR SETTING UP HIGH-SPEED LINK IN WLAN SYSTEM - The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for setting up a high-speed link in a WLAN system. A method for a station (STA) setting up the high-speed link in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: transmitting to an access point (AP) a request frame including a generic advertisement service (GAS) configuration change query; and receiving from the AP a response frame including response information with respect to the GAS configuration change query, wherein the response information may include GAS step skipping information when AS information saved in the STA matches the GAS information saved in the AP. | 03-19-2015 |
