Abstract

L'invention concerne un procédé et un système pour configurer une ressource de service non programmée, et un organe de commande de réseau radio. Le procédé comporte les étapes suivantes: l'organe de commande de réseau radio configure un ou plusieurs flux MAC-d de type non programmé pour une installation d'abonné utilisant un service non programmé, et configure ensuite une ressource de couche physique non programmée; quand le(s) flux MAC-d de type non programmé de l'installation d'abonné comporte(nt) des données à transmettre, celles-ci sont envoyées sur la ressource de couche physique non programmée. Selon l'invention, les différents flux MAC-d d'E-DCH de service non programmé d'un même utilisateur peuvent être multiplexés et partager une ressource de couche physique non programmée, ce qui permet d'améliorer l'utilisation de la ressource.
