CA 2672697

Disclosed is a method including having an ongoing communication session via a packet switched network, transferring said communication session from the packet switched network to a second network providing both packet and circuit switched access, and informing an application server maintaining said ongoing communication session that the communication session is to be split into a packet switched part and a circuit switched part. Also disclosed is a method in an application server, including receiving, from a first communication device, an indication that a communication session between the first communication device and a second communication device is to be split into a packet switched part and a circuit switched part, waiting for to receive transfer requests of both the packet switched partand the circuit switched part, and informing the second communication device of the split.

L'invention concerne un procédé, comportant les étapes consistant à tenir une session de communication établie, via un réseau de commutation de paquets, transférer ladite session de communication du réseau de commutation de paquets vers un second réseau permettant l'accès à la commutation à la fois de paquets et de circuits, et informer un serveur d'applications entretenant ladite session de communication établie que la session de communication doit être répartie en une partie de commutation de paquets et une partie de commutation de circuits. L'invention concerne également un procédé, utilisé dans un serveur d'applications, comportant les étapes consistant à recevoir, d'un premier dispositif de communication, une indication selon laquelle une session de communication entre le premier dispositif de communication et un second dispositif de communication doit être répartie en une partie de commutation de paquets et une partie de commutation de circuits, attendre la réception de demandes de transfert provenant à la fois de la partie de commutation de paquets et de la partie de commutation de circuits et informer le second dispositif de communication de la répartition.
