Abstract

Des modes de réalisation de la présente demande divulguent un procédé de commande d'itinérance dans un réseau local, ainsi qu'un appareil associé, qui sont utilisés pour mettre en œuvre une commande de transfert intercellulaire en itinérance sur un AP. Le procédé décrit dans les modes de réalisation de la présente demande consiste : à lancer, par un premier AP, une demande d'authentification et d'association sur au moins un AP devant être authentifié, puis à déterminer, par le premier AP, que ledit AP devant être authentifié réussit l'authentification et l'association du premier AP, et à déterminer, par le premier AP, que l'AP réussissant l'authentification et l'association est un second AP, un protocole de réseautage distribué pris en charge par au moins un second AP étant différent d'un protocole de réseautage distribué pris en charge par le premier AP, ou bien le premier AP ne prenant pas en charge un protocole de réseautage distribué, ou bien au moins un second AP ne prenant pas en charge un protocole de réseautage distribué.
