CA 2626222

The invention relates to a method for the mapping of packet flows onto bearers in a communication system. The establishment of a session between a terminal and a remote terminal is initiated. Information on the session and packet flows associated with it is received to a second network node. A first network node obtains from the second network node one or two packet classifiers for each of the packet flows. At least a first bearer belonging to the bearers is established between the terminal and the first network node. A packet associated with the first bearer is received in the first network node. The packet is matched with the one or two packet classifiers associated with each of the packet flows to determine a first packet flow among the packet flows. A mapping is established between the first packet flow and the first bearer in the first network node.

L'invention concerne un procédé pour la mise en corrélation de flux de paquets avec des porteurs dans un système de communication. L'établissement d'une session entre un terminal et un terminal distant est déclenché. Des informations sur la session et les flux de paquets associés à celle-ci sont reçues au niveau d~un second nAEud de réseau. Un premier nAEud de réseau obtient du second nAEud de réseau un ou deux classificateurs de paquets pour chacun des flux de paquets. Au moins un premier porteur appartenant aux porteurs est établi entre le terminal et le premier nAEud de réseau. Un paquet associé au premier porteur est reçu dans le premier nAEud de réseau. Le paquet est mis en correspondance avec le ou les classificateurs de paquets associés à chacun des flux de paquets pour déterminer un premier flux de paquets parmi les flux de paquets. Une mise en corrélation est établie entre le premier flux de paquets et le premier porteur dans le premier nAEud de réseau.
