The present invention relates to a cellular radio communication system comprising a number of base stations (BS1', ...,BS7'), each of which serves a cell (C1',...,C7'), and a number of switching arrangements each serving a number of base stations, and a number of mobile stations (MS1). Traffic channels are provided for communication of speech and/or circuit switched data and control channels are provided for communication of signalling information and/or synchronisation information. The system supports communication of packet data. A number of resource management nodes (10) are provided for managing channel resources and a number of packet data handling nodes are provided for handling packet data services. At least in some of the cells resources can be allocated on demand for communication of packet data in the respective cells. The invention also relates to a method of allocating channel resources in cellular radio communication system supporting packet data communication.
L'invention concerne un système de radiocommunication comprenant un certain nombre de stations de base (BS1', ..., BS7') qui desservent chacune une cellule (C1',...,C7'), un certain nombre de systèmes de commutation qui desservent chacun un certain nombre de stations de base, et un certain nombre de stations mobiles (MS1). Les canaux de trafic sont conçus pour la communication de la parole et/ou de données à commutation de circuits. Des canaux de commande permettent la communication d'informations de signalisation et/ou d'informations de synchronisation. Le système supporte la communication de paquets de données. Un certain nombre de noeuds gestionnaires de ressources (10) permettent de générer les ressources canaux et un certain nombre de paquets de données gérant des noeuds permettent de gérer les services de paquets de données. Au moins dans certaines cellules, des ressources peuvent être affectées sur demande de communication de paquets de données dans les cellules respectives. L'invention concerne également un procédé d'affectation des ressources canal dans un système de radiocommunication cellulaire supportant la communication de paquets de données.
