Patent

CA 2394711

There is provided a novel architecture for transmitting multimedia data with different QoSs in a mobile communication system. In a protocol structure according to the present invention, an RLP layer receives data with different QoSs and dividing the data into datagrams according to the QoSs, a MUX layer multiplexes the datagrams received from the RLP layer and outputs multiplexed TU data, and a QCCH receives the multiplexed TU data and outputs TU blocks with the QoSs by puncturing and repeating information added according to the QoSs for the multiplexed TU data.

L'invention concerne une nouvelle architecture permettant de transmettre des données multimédia avec différentes qualités de service (QoSs) dans un système de communication mobile. Dans une structure de protocole selon la présente invention, une couche de protocole de liaison radio (RLP) reçoit des données avec différentes QoSs et divise ces données en datagrammes selon les QoSs. Une couche de multiplexage (MUX) multiplexe les datagrammes reçus par la couche RLP et sort des données de stations de transport (TU) multiplexées. Enfin, un canal de contrôle qualité (QCCH) reçoit les données TU multiplexées et sort des blocs TU avec les QoSs en perforant et répétant des informations ajoutées selon les QoSs des données TU multiplexées.
