The present invention relates to a mobile communication system which comprises a base station (BTS1) having a data transmission connection to a mobile services switching centre (MSC) through a transcoder unit (TRCU). In order to improve the data transmission connection between the base station and the transcoder unit, the data transmission connection in question is partly composed of a packet-switched data transmission connection (4) to which a converter means (3) is arranged comprising means for converting the TRAU frame received into a packet to be transmitted over the packet-switched connection (4), the conversion including the removal of bits included in the TRAU frame and not needed on the packet-switched connection (4).

Cette invention concerne un système de communication mobile comprenant une station de base (BTS1) qui est reliée par une connexion de transmission de données et par l'intermédiaire d'une unité de transcodage (TRCU) à un centre de commutation de services mobile (MSC). Afin d'améliorer la connexion de transmission de données entre la station de base et l'unité de transcodage, ladite connexion se compose partiellement d'une connexion de transmission de données commutée par paquets (4) à laquelle est associé un système de conversion (3). Ce système de conversion comprend un dispositif qui permet de convertir la trame TRAU reçue en un paquet qui sera transmis par la connexion commutée par paquets (4). Cette conversion consiste à éliminer les bits que contient la trame TRAU et qui ne sont pas utiles dans la connexion commutée par paquets (4).
