    Abstract: A device and method for active scanning are disclosed. The active scanning method in a wireless LAN can comprise the steps of: allowing an AP to receive a probe request frame containing an the AP identifier; determining whether the AP is a target AP or a non-target AP on the basis of the AP identifier; and performing back-off for the transmission of a probe response frame from a second interval after a first interval is terminated in a minimum channel interval when the AP is a non-target AP. Therefore, the present invention can prevent probe response frames from flooding a STA in a short period of time by distributing intervals in which probe response frames are received to the STA. In addition, the time used by the STA to perform active scanning can be reduced.

    Abstract: The present invention relates to a method and apparatus for associating a station (STA) with an access point (AP). 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.
