Abstract

L'invention concerne un procédé de transmission permettant le DAMA (accès multiple avec assignation en fonction de la demande) dans un système de communication mobile. Ledit procédé est basé sur le système de communication mobile et un système de transmission par satellite. Le système de communication mobile forme plusieurs sous-systèmes, la transmission de données entre les différents sous-systèmes étant assurée par le système de transmission par satellite. Les données entre les sous-systèmes sus-mentionnés sont converties en nouvelles données conformes au protocole de transport/protocole Internet et sont transmises par l'intermédiaire d'un dispositif satellite à interface de protocole Internet. Le procédé de l'invention peut être adapté pour permettre le réglage de la largeur de bande, l'économie de largeur de bande et un DAMA réel.
