The present invention relates to a mobile communication system comprising a rate adaptation unit (TC) which communicates with a base station system via first data transmission channels (Ater1 - Ater4) and with a mobile services switching centre (MSC) via second data transmission channels (A1 - A4). To enable available data transmission capacity to be utilized as flexibly as possible, the base station system comprises: allocation means (7) which keep a record of the first data transmission channels (Ater1 - Ater4) and which are responsive to a message sent by the mobile services switching centre (MSC) for allocating one or more free first data transmission channels (Ater2, Ater4) for the call, and transmission means (8) which are arranged to send the mobile services switching centre (MSC) a message which indicates which second data transmission channel (A2) the rate adaptation unit (TC) selects for the call when the allocation means (7) have allocated one or more first data transmission channels (Ater2, Ater4) for the call.

La présente invention concerne un système de communications mobile comportant un adaptateur de débit (TC) en communication, d'une part avec un système de station de base via des premiers canaux de données (Ater1 - Ater4), et d'autre part avec un centre de commutation de services mobiles (MSC) via des seconds canaux de données (A1 - A4). Pour permettre une utilisation aussi souple que possible de la capacité de transmission de données disponible, le système de la station de base comporte un organe d'affectation (7) qui tient à jour une liste des premiers canaux de données (Ater1 - Ater4) et qui réagit à un message envoyé par le centre de commutation de services mobiles (MSC) en vue de l'affectation à l'appel de l'un au moins des premiers canaux de données libres (Ater2 - Ater4). Le système de la station de base comporte également des organes de transmission (8) qui sont configurés de façon à envoyer au centre de commutation de services mobiles (MSC) un message indiquant celui des seconds canaux de données (A1 - A4) qui est retenu par l'adaptateur de débit (TC) pour l'appel une fois que l'organe d'affectation (7) a affecté l'un au moins des premiers canaux de données (Ater2 - Ater4) pour l'appel.
