Title (EN) METHOD AND APPARATUS FOR TRANSMITTING WIRELESS LAN-BASED DATA TRAFFIC, AND COMPUTER PROGRAM
(FR) PROCÉDÉ ET APPAREIL DESTINÉS À LA TRANSMISSION D'UN TRAFIC DE DONNÉES BASÉ SUR UN LAN SANS FIL, ET PROGRAMME INFORMATIQUE
(KO) 무선랜에 기반한 데이터 트래픽 전송 방법, 장치 및 컴퓨터 프로그램
Abstract: front page image
(EN)The present invention relates to a method and an apparatus for transmitting wireless LAN-based data traffic, and a computer program and, more particularly, to a method and an apparatus for transmitting wireless LAN-based data traffic, and a computer program, the method and the apparatus being capable of guaranteeing service quality (QoS) such as a multimedia service and the like by more efficiently using a wireless resource through a change in a primary channel and transmitting a data frame on the basis of a wireless resource reservation using RTS/CTS controls and the like. Disclosed in the present invention is a method for transmitting wireless LAN-based data traffic, comprising: a channel allocation step for allocating a plurality of channels including a primary channel and a secondary channel so as to enable an access point (AP) to perform data transmission and reception with a station (STA); and a primary channel changing step for transmitting an RTS frame in each of the plurality of channels to the STA and changing the primary channel when a CTS frame is not received in the primary channel and/or the secondary channel.
(FR)La présente invention concerne un procédé et un appareil destinés à la transmission d'un trafic de données basé sur un réseau local sans fil, et un programme informatique et, plus particulièrement, un procédé et un appareil destinés à la transmission d'un trafic de données basé sur un réseau local sans fil (LAN), et un programme informatique, le procédé et l'appareil étant susceptibles de garantir une qualité de service (QoS) tel qu'un service multimédia et analogue(s) par l'utilisation plus efficace d'une ressource sans fil par l'intermédiaire d'une modification dans un canal primaire et la transmission d'une trame de données sur la base d'une réservation de ressource sans fil à l'aide de commandes RTS/CTS et analogue(s). La présente invention concerne un procédé destiné à la transmission de trafic de données basé sur un réseau local sans fil (LAN), consistant : à attribuer un canal destiné à attribuer une pluralité de canaux comprenant un canal primaire et un canal secondaire de façon à permettre à un point d'accès (AP) de réaliser une transmission et une réception de données avec une station (STA) ; et à modifier le canal primaire destiné à la transmission d'une trame RTS dans chacun de la pluralité de canaux à la STA et à modifier le canal primaire lorsqu'une trame CTS n'est pas reçue dans le canal primaire et/ou le canal secondaire.
(KO)본 발명은 무선랜에 기반하여 데이터 트래픽을 전송하기 위한 방법, 장치 및 컴퓨터 프로그램에 관한 것으로서, 보다 구체적으로는, Primary 채널을 변경을 통해 무선 자원을 보다 효율적으로 이용하고, 또한 RTS/CTS 제어 등을 이용한 무선자원 예약에 기반하여 데이터 프레임을 전송하여 멀티미디어 서비스 등에 대한 서비스 품질(QoS)을 보장할 수 있도록 하는 무선랜에 기반한 데이터 트래픽 전송 방법, 장치 및 컴퓨터 프로그램에 관한 것이다. 본 발명에서는, 본 발명은 AP(Access Point)가 STA(Station)와의 데이터 송수신을 위하여 Primary 채널 및 Secondary 채널을 포함하는 복수의 채널을 할당하는 채널 할당 단계; 및 상기 복수의 채널 각각에서 RTS 프레임을 상기 STA로 송신하고, 상기 Primary 채널 및 Secondary 채널 중 어느 하나 이상의 채널에서 CTS 프레임이 수신되지 않는 경우, Primary 채널을 변경하는 Primary 채널 변경 단계;를 포함하는 무선랜에 기반한 데이터 트래픽 전송 방법을 개시한다.
