A method for setting up a session having a defined quality of service between a first and a second end-host, said first end-host belonging to a first non-stationary network being able to move and to connect directly or through one or more intermediate networks to a first stationary access network, said second end-host being connected to a second stationary access network which can connect to said first stationary access network, said method comprising:
providing a quality of service controller in each stationary and non-stationary network, said quality of service controller being aware of the nodes of the network to which it belongs and their capabilities and being responsible for the allocation of resources necessary for a session;
providing a session initiation server in each stationary access network for initiating a session between hosts, whereas the session initiation server and the quality of service controller in a fixed stationary network both are aware of each other;
executing a discovery procedure to enable the first end-host to discover the session initiation server of the first stationary access network and to register therewith and for discovering the quality of service controller of the non-stationary network;
in response to a session initiation request received by the session initiation server of said first stationary access network, triggering the quality of service controller of said first stationary access network and triggering the quality of service controller of said first non-stationary network to allocate resources for said session in their respective networks.
