A method for seamless channel change in a wireless local area network having a station STA (204) and an access point AP (202) begins with sending a channel change intention message from the AP to STA (210). A channel change response message (212) is sent from STA to the AP, informing the AP whether the STA will follow the channel change. The AP determines whether to proceed with the channel change, and performs the change if the determination is positive.

L'invention concerne un procédé destiné à un changement de canal sans interruption dans un réseau local sans fil comprenant une station (STA) et un point d'accès (AP). Ce procédé consiste tout d'abord à transmettre un message d'intention de changement de canal à la station, depuis le point d'accès. Ensuite, un message de réponse au changement de canal est transmis au point d'accès, depuis la station, indiquant au point d'accès si la station va suivre le changement de canal. Finalement, le point d'accès détermine s'il poursuit le changement de canal et, dans la positive, change de canal.
