Abstract

La présente invention concerne un procédé de commande de point d'accès Wi-Fi et un point d'accès Wi-Fi. Le procédé consiste à : faire entrer un point d'accès (AP) dans un flux de traitement à faible consommation d'énergie ; y faire sélectionner, par l'AP, au moins une période de trame balise en tant que période de trame balise à faible consommation d'énergie ; dans chaque période de trame balise à faible consommation d'énergie, détecter une demande d'accès d'une station dans une première période de temps définie, puis arrêter de détecter la demande d'accès de la station dans une seconde période de temps définie. En conséquence, l'AP de la présente invention n'est pas toujours dans un état de forte consommation d'énergie et sélectionne au moins une période de trame balise en tant que période de trame balise à faible consommation d'énergie lorsqu'il n'accède pas à une station. Comparé à l'état de la technique selon lequel l'AP est toujours dans un mode de fonctionnement à forte consommation d'énergie, la présente invention réduit la consommation d'énergie de l'AP lorsqu'il n'accède pas à une station, c'est-à-dire que la consommation d'énergie de la fonction de routage Wi-Fi est réduite.
