Abstract

La présente invention concerne une méthode de distinction de service dans un réseau de communication comprenant principalement les étapes suivantes : lorsque le chemin de données utilisé dans la session (flux de service) doit être libéré, un message de libération de chemin de données incluant l’information identificateur de session est émis et le chemin de données de la session correspondante est libéré par les entités réseau respectives en fonction de l’information identificateur de session dans le message de libération de chemin de données. La libération peut être initiée non seulement par la BS mais aussi par ASN GW. Ainsi, l’invention permet au processus de signalisation WiMax de gérer différentes QoS pour différentes sessions dans la même MSS. Simultanément, l’invention ajoute le processus initiant l’établissement de session de ASN-GW dans WiMax à la BS et la condition d’application d’établissement de chemin de données parmi WiMax ASN GW. En conclusion, dans l’invention, tous les messages de requête/réponse d’établissement de chemin de données peuvent transporter des informations de QoS à incorporer dans le processus existant local de négociation de QoS.
