1. A method for mapping at least two packet flows onto at least two bearers in a communication system comprising at least a terminal, a first network node and a second network node, the method comprising:

  • initiating an establishment of a session between said terminal and a remote terminal;

    receiving information about said session and said at least two packet flows in said second network node;

    agreeing to the establishment of said at least two bearers between said terminal and said first network node;

    said first network node obtaining from said second network node a packet classifier for each of said at least two packet flows;

    establishing at least a first bearer of said at least two bearers;

    receiving a packet associated with said first bearer in said first network node;

    matching said packet with at least one of said packet classifiers to determine a first packet flow among said at least two packet flows; and

    establishing a mapping between a packet flow pair, said packet flow pair comprising said first packet flow and a corresponding opposite direction packet flow, and said first bearer in said first network node.
