Title (EN) SERVING BASE STATION SELECTION DURING SOFT HANDOVER
(FR) SELECTION DE LA STATION DE BASE DE SERVICE LORS D'UN TRANSFERT LOGICIEL
Abstract: front page image
(EN)The present invention relates to methods for controlling a plurality of base stations in a mobile communication system comprising a communication terminal, the plurality of base stations and a control unit connected to the plurality of base stations, wherein the communication terminal is in a soft handover. Further, the present invention relates to methods for signaling uplink channel quality characteristics, that are considered when controlling the plurality of base stations. Finally, the present invention relates to a base station, the control unit and the communication terminal which are specifically adapted to perform the control method and the signaling method respectively. To reduce the signaling load on the wired interface between a base station and a control unit the present invention selects a serving base station based on uplink channel quality characteristics and controls one or more of the base stations except the serving base station not to transmit data via the wired interface.
(FR)L'invention concerne des procédés permettant de commander plusieurs stations de base dans un système de communication mobile comprenant un terminal de communication, lesdites stations de base et une unité de commande reliée à ces stations de base, le terminal de communication étant en mode transfert logiciel. En outre, l'invention concerne des procédés permettant de signaler des caractéristiques de qualité de voies de liaison montantes, prises en compte lors la commande de la pluralité de stations de base. Enfin, l'invention concerne une station de base, l'unité de commande et le terminal de communication spécifiquement conçus pour exécuter le procédé de commande et le procédé de signalisation, respectivement. Pour réduire la charge de signalisation sur l'interface câblée entre une station de base et une unité de commande, on choisit une station de base de service en fonction des caractéristiques de qualité des voies de liaison montantes et on commande à une ou plusieurs stations de base, à l'exception de la station de base de service, de ne pas transmettre des données par l'interface câblée.
