Abstract

La présente invention concerne une entité de classification de trame (FCE) destinée à une station dans un ensemble de services basiques (BSS) d'un réseau local radio (WLAN). Cette entité (FCE) comprend un tableau de classification. Ce tableau de classification est situé logiquement au niveau d'une sous couche de commande de lien logique (LLC) de la station, et il contient au moins une rubrique de classement. La station peut donc comprendre un coordinateur de point (PC) ou être une station non PC. Chaque rubrique de classement comprend au moins un identificateur de flux virtuel (VSID), une valeur de priorité de recherche, et au moins un paramètre de classement. Chaque rubrique de classement du tableau de classification est agencée dans un ordre hiérarchique fondé sur la valeur de priorité de recherche incluse dans la rubrique de classement. L'entité FCE reçoit au moins une trame de données descendue à la sous couche LLC de la station à partir d'une couche supérieure de cette station. L'entité FCE classe ensuite chaque trame de données reçue vers un VISD en examinant cette trame de données par rapprochement du tableau de classification de la station. Lorsque cette trame de données est examinée et que le VSID de cette trame de données est contenu dans une rubrique de classement du tableau de classification, ce VSID est associé à un ensemble de paramètres QOS destinés à transporter cette trame de données entre des entités LLC homologues du BSS. Lorsque les informations de classification de trame contenues dans une trame de données reçue ne sont pas incluses dans une rubrique de classement du tableau de classification, le résultat de classification est exprimé dans un VSID spécial qui n'est pas associé à un ensemble de paramètres QOS, et cet ensemble et cette trame de données sont transportés, dans la mesure du possible, entre des entités LLC homologues du BSS.
