Abstract

L'invention concerne un procédé et un système de communication destinés à la gestion d'un service mode paquet. Ce système comprend un réseau central basé sur paquets (CNW) et un réseau d'accès (ANW). Selon l'invention, le noeud de commande (EN) placé entre le réseau central (CNW) et le réseau d'accès (ANW) au niveau de l'interface permet de commander la transmission de données multimédia dans les paquets de données et de l'intégrer à la transmission de données de et vers le dispositif de communication mobile (MS) par l'interface radio du réseau d'accès. L'invention offre l'avantage de permettre, grâce au noeud de commande, une intervention active dans la signalisation de la transmission des données multimédia sous forme de paquet de données, c'est-à-dire que cette signalisation n'a plus besoin d'être transparente par rapport au dispositif de communication. L'invention offre un autre avantage, à savoir que l'intégration de la commande de la transmission de données multimédia permet de mieux adapter les flux de données aux ressources radio et/ou aux exigences du dispositif de communication mobile.
