Abstract

Les modes de réalisation de la présente invention concernent un procédé, un appareil et un dispositif de traitement d'informations d'état de zone tampon. Dans le cadre du procédé : un processeur d'application (AP) d'un équipement d'utilisateur (UE) acquiert des informations d'état de zone tampon et envoie les informations d'état de zone tampon à un processeur de bande de base numérique (BP) de l'UE ; et le processeur BP de l'UE rapporte à une station de base une signalisation d'unité de données de protocole (PDU) de contrôle d'accès au support (MAC) qui transporte les informations d'état de zone tampon pour que la station de base attribue une ressource à l'UE selon les informations d'état de zone tampon dans la signalisation PDU MAC. Le procédé, l'appareil et le dispositif de traitement d'informations d'état de zone tampon selon les modes de réalisation de la présente invention peuvent réduire la complexité d'un système.
