Abstract
(EN)
Disclosed are a method and an apparatus for scanning in a wireless LAN. The method may comprise the following steps: an STA determining identifier information of an access point that is to be included in a probe request frame as a wildcard service set identifier (SSID) and a wildcard basic service set identifier (BSSID), on the basis of a first MAC sublayer management entity (MLME); the STA receiving from the AP a frame including information on the BSSID of the AP and the SSID of the AP before a probe delay time expires; the STA determining wither the AP is a target AP on the basis of the BSSID and the SSID; the STA re-determining the identifier information of the AP that is to be included in the probe request frame on the basis of the BSSID and the SSID, when the AP is the target AP; and the STA unicasting a probe request frame that is re-determined on the basis of the BSSID and the SSID.

L'invention concerne un procédé et un appareil de balayage dans un LAN sans fil. Le procédé peut comprendre les étapes suivantes : la détermination, par une STA, d'informations d'identification d'un point d'accès qui doit être inclus dans une trame de requête d'analyse, comme un identifiant de réseau sans fil (SSID) à caractère de remplacement et un identifiant de réseau sans fil de base (BSSID) à caractère de remplacement, sur la base d'une première entité de gestion de sous-couche MAC (MLME) ; la réception, par la STA depuis l'AP, d'une trame contenant des informations sur le BSSID de l'AP et le SSID de l'AP avant qu'un délai d'analyse n'expire ; la détermination, par la STA, pour savoir si l'AP est un AP cible, sur la base du BSSID et du SSID ; la nouvelle détermination, par la STA, des informations d'identifiant de l'AP qui doivent être incluses dans la trame de requête d'analyse, sur la base du BSSID et du SSID, lorsque l'AP est l'AP cible ; et l'envoi individuel, par la STA, d'une trame de requête d'analyse qui est nouvellement déterminée sur la base du BSSID et du SSID.

무선랜에서 스캐닝 방법 및 장치가 개시되어 있다. STA이 제1 MLME (MAC sublayer management entity) 스캔 요청 정보에 기반하여 프로브 요청 프레임에 포함할 AP (access point)의 식별자 정보를 와일드카드 SSID(service set identifier) 및 와일드카드 BSSID (basic service set identifier)로 결정하는 단계, STA이 프로브 딜레이 시간이 만료하기 전에 AP로부터 AP의 BSSID 및 AP의 SSID에 대한 정보를 포함하는 프레임을 수신하는 단계, STA이 BSSID 및 SSID를 기반으로 AP가 타겟 AP인지 여부를 판단하는 단계, AP가 타겟 AP인 경우, STA이 BSSID 및 SSID를 기반으로 프로브 요청 프레임에 포함될 AP의 식별자 정보를 재결정하는 단계와 STA이 BSSID 및 SSID를 기반으로 재결정된 프로브 요청 프레임을 AP로 유니캐스트하는 단계를 포함할 수 있다.
