The invention relates to a method and a communications system for handling a packet service with a packet-based core network (CNW) and an access network (ANW). According to the subject-matter of the invention, the control node (EN) which is arranged at an interface between the core network (CNW) and access network (ANW) can control the transmission of multimedia data in the packet data and integrate it into the data transmission from and to the mobile communications device (MS) via the radio interface of the access network. The advantage of the invention is that the control node can actively intervene in the signaling of the transmission of the multimedia data as packet data, i.e. this signaling no longer needs to be carried out transparently with respect to the mobile communications device. A further advantage is that as a result of the integration of the supervision of the multimedia data transmission, the data streams can be better adapted to the radio resources and/or to the requirements of the mobile communications device.

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.
