Abstract

L'invention concerne un procédé et un système de traitement d'envoi de trames de gestion. Le procédé comprend les étapes suivantes : un dispositif de point d'accès diffuse une trame de balise à destination d'un dispositif de station, la trame de balise contenant des informations d'indication d'un segment de temps destiné à l'envoi d'une trame de gestion, et les informations d'indication servant à informer que le dispositif de station est uniquement autorisé à envoyer la trame de gestion dans le segment de temps destiné à l'envoi de la trame de gestion ; et le dispositif de point d'accès reçoit, dans le segment de temps destiné à l'envoi de la trame de gestion, la trame de gestion envoyée par le dispositif de station. Dans les modes de réalisation de la présente invention, en transportant des informations d'indication d'un segment de temps destiné à l'envoi d'une trame de gestion, un dispositif de station reçoit l'ordre d'envoyer la trame de gestion dans le segment de temps destiné à l'envoi de la trame de gestion, ce qui améliore le taux d'utilisation d'un canal radio.
