Abstract

La présente invention se rapporte au domaine technique de la communication et concerne un procédé et un appareil de gestion de la qualité de service (QoS) pour des SRB. Le procédé consiste : à envoyer, après l'établissement d'une connexion RRC à un équipement utilisateur, un premier message de transfert direct initial à une MME ; à envoyer, par la MME, une première requête d'informations d'abonnement d'utilisateur à un serveur d'abonné domestique (HSS) ; à renvoyer, par le HSS, un identifiant de priorité, correspondant à un identifiant de l'équipement utilisateur, l'identifiant de priorité indiquant une priorité de l'équipement utilisateur ; et à réaliser, par une station de base, en fonction de l'identifiant de priorité, un traitement de planification sur des messages qui portent l'identifiant de priorité et qui sont envoyés par l'équipement utilisateur à l'aide des SRB. La présente invention concerne un mécanisme de gestion de la QoS, basé sur un identifiant de priorité, permettant la fourniture d'un identifiant de priorité à un équipement utilisateur lorsque ledit équipement utilisateur a terminé l'attachement d'accès initial de telle sorte qu'une station de base peut ensuite effectuer, en fonction de l'identifiant de priorité, un traitement de planification sur des messages de données envoyés à l'aide des SRB, réaliser une planification différenciée pour les SRB et améliorer l'adaptabilité du service. En outre, pour un équipement utilisateur présentant une exigence élevée d'instantanéité, un traitement peut être réalisé de manière préférentielle en fonction d'un identifiant de priorité pour réduire les retards de traitement.
