1. A method of arranging transmission of packet data in a system comprising a mobile terminal, a wireless local network and a mobile network, the method comprising:
signaling end-to-end service related parameters for communication between the mobile terminal and the wireless local network, communicating a resource authorization identifier from a policy decision function to the mobile terminal via the wireless local network, wherein the resource authorization identifier is an authorization token in an internet protocol multimedia subsystem, receiving a request for authorization from the mobile network on the basis of the resource authorization identifier, receiving an authorization response to bind a tunnel between the mobile terminal and the mobile network to an end-to-end data flow of the mobile terminal, wherein the authorization response comprises identification information on the end-to-end data flow and tunnel identification information identifying the tunnel, transmitting at least one filter or gate parameter to the mobile network, wherein the at least one filter or gate parameter is associated with the tunnel, and filtering or gating is arranged in the mobile network to or from the tunnel based on the association, wherein a first tunnel between the mobile terminal and a first network element of the mobile network is established for end-to-end service parameter signaling, and a second tunnel between the mobile terminal and a second network element of the mobile network is established for user data transmission after the reception of resource authorization identifier, and wherein the receiving the request for authorization from the mobile network on the basis of the resource authorization identifier comprises receiving the request at the policy decision function from a packet data gateway (PDG), wherein the PDG is configured to arrange a binding of the tunnel on the basis of the authorization from the policy decision function. |
