Abstract: front page image
(EN)The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for updating system information in a wireless LAN system. A method for a station (STA) to update system information in a wireless communication system according to one embodiment of the present invention comprises the steps of: if the value of a change sequence field received by the STA from an access point (AP) is different from the value of the change sequence field stored in the STA, transmitting, to the AP, a probe request frame including the change sequence field set to the value of the change sequence field stored in the STA; and a step of receiving, from the AP, a probe response frame responding to the probe request frame including the change sequence field.
(FR)La présente invention concerne un système de communications sans fil, et plus particulièrement un procédé et un appareil de mise à jour d'informations de système dans un système de réseau local sans fil. Un procédé destiné à permettre à une station (STA) de mettre à jour des informations de système dans un système de communications sans fil selon un mode de réalisation de la présente invention comporte : une étape consistant, si la valeur d'un champ d'ordre de modification reçu par la STA en provenance d'un point d'accès (AP) est différente de la valeur du champ d'ordre de modification conservée dans la STA, à envoyer à l'AP une trame de demande de sondage comprenant le champ d'ordre de modification réglé à la valeur du champ d'ordre de modification conservée dans la STA ; et une étape consistant à recevoir, en provenance de l'AP, une trame de réponse de sondage réagissant à la trame de demande de sondage comprenant le champ d'ordre de modification.
(KO)본 발명은 무선 통신 시스템에 대한 것으로, 보다 상세하게는 무선랜 시스템에서 시스템 정보를 업데이트하는 방법 및 장치가 개시된다. 본 발명의 일 실시예에 따른 무선 통신 시스템의 스테이션(STA)에서 시스템 정보를 업데이트하는 방법은, 상기 STA이 액세스 포인트(AP)로부터 수신한 변경 시퀀스(change sequence) 필드의 값이, 상기 STA이 저장하고 있는 변경 시퀀스 필드의 값과 상이한 경우, 상기 STA이 저장하고 있는 변경 시퀀스 필드의 값으로 설정된 변경 시퀀스 필드를 포함하는 프로브 요청 프레임을 상기 AP로 전송하는 단계; 및 상기 변경 시퀀스 필드를 포함하는 프로브 요청 프레임에 응답하는 프로브 응답 프레임을 상기 AP로부터 수신하는 단계를 포함할 수 있다.
