Abstract: A method of arranging the transmission of packet data in a system comprising a mobile terminal, a wireless local network and a mobile network that includes end-to-end service related parameters that are signalled via a separate signalling element. A resource authorization identifier is transmitted to the mobile network via the local network. Authorization is requested from the signalling element on the basis of the resource authorization identifier. A tunnel between the mobile terminal and the mobile network is bound to the end-to-end data flow of the mobile terminal on the basis of an authorization from the signalling element and tunnel identification information identifying the tunnel.

Abstract: The invention relates to a method of transmitting packet data from a first subsystem to a wireless terminal device via the network node of a second subsystem. In the method, at least one filter is formed to guide mapping of at least one data flow of the first subsystem to at least one data flow of the second subsystem. At least one filter is attached to at least one data flow of the second subsystem. The filter comprises at least part of the interface identifier of the IP address, which at least part of the interface identifier is allocated in the wireless terminal device. Hereby, mapping of the data flow of the first subsystem to the data flow of the second subsystem is performed on the basis of the interface identifiers of the destination IP addresses in the received packets.

Abstract: The invention relates to transfer of packet data from a first subsystem via a network node in a second subsystem to a terminal in the second subsystem. The method includes negotiating identifiers identifying a data flow of the first subsystem via a separate signalling element during the set-up of an application-plane logical connection of the terminal. The identifiers are transmitted from the signalling element to the network node. In the method, a filter is generated at least on the basis of the identifiers for directing the mapping of at least one data flow of the first subsystem to at least one data flow of the second subsystem. The filter is bound to at least one data flow of the second subsystem, and at least one data flow of the first subsystem is mapped to at least one data flow of the second subsystem on the basis of the filter.

Abstract: The invention relates to a method for supporting a transmission of data packets from a node attached to a mobile communication network to a first unit. In order to enable a second unit providing or forwarding the data packets to the node to influence the QoS for the transmission, it is proposed that the method comprises transmitting data packets of a specific data flow from the node to the first unit using a quality of service treatment which is selected based on a quality of service treatment associated with a quality of service identifier. The quality of service identifier is inserted by a second unit to each packet of the specific data flow. The invention relates equally to a terminal equipment, to a node, to a mobile communication network and to a system comprising means for realizing the proposed method.

Abstract: The invention relates to a method for arranging packet-switched data transmission in a wireless system. The method activates a packet data transmission context between a mobile station and a network element providing wireless packet-switched data transmission, a first address being attached to the transmission context. In addition to the first address, a second address is attached to the transmission context. The packets, whose IP address field includes the second address or just the first address, are transmitted using the established transmission context.
