The present invention relates to a mobile communication system comprising a mobile services switching center, a base station and a transcoder. The transcoder receives from the base station frames containing speech parameters, and from the mobile services switching centre speech signals which it encodes into speech parameters to be transmitted to the base station in the frames. To enable the cooperation between the transcoder and the base station to be controlled as simply as possible, the mobile communication system comprises a base station controller for transmitting predetermined control information to the base station, whereby base station is arranged to control the operation of the transcoder via the telecommunication connection in response to the reception of the control information.
L'invention concerne un système de télécommunication mobile comprenant un centre de commutation de services mobile (MSC), une station de base (BTS1, BTS2) et un transcodeur (TRAU), système dans lequel le transcodeur reçoit de la station de base (BTS1, BTS2), des trames contenant des paramètres de conversation et, du centre de commutation de services mobile (MSC), des signaux de conversation qu'il encode dans les paramètres de conversation à transmettre à la station de base /BTS1, BTS2) dans les trames. Afin que la coopération entre le transcodeur et la station de base soit commandée aussi simplement que possible, le système de télécommunication mobile comprend des moyens de commande (BSC) destinés à transmettre des informations de commande prédéterminées à la station de base (BTS1, BTS2), la station de base (BTS1, BTS2) étant ainsi agencée pour commander le fonctionnement du transcodeur (TRAU) via ladite connexion de télécommunication, en réponse à la réception des informations de commande.
