A satellite communications system provides a communications service to a mobile terminal (2) on which different communications applications (4a to 4d) may be run. Calls are set up between any of the applications (4a to 4d) via a satellite (12) to a network management centre (18) which provides different service adaptors (20a to 20d) which adapt the calls to different types of service provided over terrestrial networks (22), such as telephony, facsimile, internet or ATM services. The bandwidth allocated to each call over the satellite link may be varied during the call according to demand either from the relevant application (4) or from the network management centre (18). Multiple calls may be connected concurrently to or from different applications running on the mobile terminal. A maximum bandwidth is allocated to each call. Efficient use is thereby made of the limited bandwidth available over the satellite (12), according to the instantaneous bandwidth requirements of different applications (4). For real-time calls requiring multiple slots per frame in a TDMA channel, the slots are mutually spaced apart to reduce delay.

L'invention concerne un système de communications par satellite fournissant des services de communications à un terminal mobile (2) sur lequel on peut faire tourner différentes applications (4a à 4d) de communications. On établit via un satellite (12), les communications entre n'importe laquelle de ces applications (4a à 4d), et un centre (18) de gestion du réseau comprenant différents adaptateurs (20a à 20d) de services qui adaptent les communications aux différents types de services assurés sur les réseaux terrestres (22), tels que la téléphonie, la télécopie, l'Internet ou les réseaux ATM. La largeur de bande attribuée à chaque communication de la liaison satellite peut être modifiée en cours de communication à la demande de l'application (4) concernée ou du centre (18) de gestion du réseau. On peut connecter simultanément plusieurs communications à destination ou en provenance d'applications tournant sur le terminal mobile. On attribue à chaque communication une largeur de bande maximale, ce qui permet une utilisation rationnelle de la bande passante limitée disponible sur le satellite (12) tenant compte des exigences instantanées en largeur de bande des différentes applications (4). Pour les communications temps réel nécessitant plusieurs créneaux temporels pour une trame sur un canal AMRT, les créneaux sont espacés les uns des autres de manière à réduire les temps d'attente.
