Abstract
(EN) Radio channel resources are allocated in a radio communications system based on whether a requested data communication requested is associated with a symmetric service or an asymmetric service. If the data communication is associated with a symmetric service, a symmetric connection between the mobile radio station and the radio network is established for communicating data packets associated with the data communication. Radio channel resources are assigned to the symmetric connection for transporting the data packets between the mobile radio station and the radio network. The symmetric connection is assigned substantially the same amount of radio channel resources in an uplink direction as in a downlink direction. In one example, the symmetric data communication is a voice over IP (VoIP) communication. One example environment is a GPRS/EDGE type system where the radio channel resources are time slots and the symmetric connection includes an uplink temporary block flow (TBF) and a downlink TBF.
(FR) Des ressources de type canaux radio sont attribuées dans un système de communications radio selon qu'une communication de données demandée est associée à un service symétrique ou à un service asymétrique. Si la communication de données est associée à un service symétrique, une connexion symétrique entre la station radio mobile et le réseau radio est établie aux fins de la transmission des paquets de données associés à la communication de données. Les ressources de type canaux radio sont attribuées à la connexion symétrique pour le transport des paquets de données entre la station radio mobile et le réseau radio. La connexion symétrique reçoit sensiblement la même quantité de ressources de type canaux radio aussi bien pour une liaison montante que pour une liaison descendante. Dans un exemple, la communication de données symétrique est une communication de voix sur IP (VoIP). Un exemple d'environnement est un système du type GPRS/EDGE dans lequel les ressources de type canaux radio sont des fenêtres temporelles et la connexion symétrique inclut un flux de blocs temporaires (TBF) de liaison montante et un TBF de liaison descendante.
