A method for managing quality of service (QoS) in a wireless local area network begins by receiving a traffic flow (302). The traffic flow is mapped to a traffic class (TC), based on QoS requirements of the traffic flow (304). A transmission budget of an access class (AC) is calculated, each AC including at least one TC (306). A determination is made whether the traffic flow can be admitted, by calculating whether the transmission budget can support the traffic flow (308). If the traffic flow is admitted, the parameters of the TC are adjusted and collisions in the TC between existing traffic flows and the newly admitted traffic flow are managed (314).

L'invention concerne un procédé de gestion de qualité de services (QoS) dans un réseau local d'entreprise sans fil permettant de recevoir un écoulement de trafic (302). Ledit écoulement de trafic est mis en correspondance avec une classe de trafic (TC) en fonction des exigences QoS dudit écoulement de trafic (304). Un budget de transmission d'une classe d'accès (AC) est calculé, chaque AC comprenant au moins une TC (306). On détermine si l'écoulement de trafic peut être admis par calcul d'un budget de transmission pouvant supporter l'écoulement de trafic (308). Lorsque ledit écoulement de trafic est admis, les paramètres de la TC sont réglés et les collisions entre les TC des écoulements de trafic existant et de l'écoulement de trafic récemment admis sont gérées (314).
