摘要： An internet packet comprises a header field, the header field including a field identifying a source address of the internet packet, a field identifying the destination address of the internet packet and a next header field identifying whether an extension header follows the header and a type of the extension header. The extension header indicates a hop-by-hop option header, the hop-by-hop extension header including a router alert option header type indicating that the extension field is optional for a router to read, and a field providing information for a gateway support node of a packet radio system network. A gateway support node is thereby provided with information, which may be required for example to support a mobile internet protocol (IP). However, by providing the router alert option field, a router is not required to read the remainder of the hop-by-hop option field. As a result, a reduction in the performance of the router in routing internet packets, which may have been incurred if the router was required to read all the hop-by-hop extension field can be limited.

摘要： A telecommunications system is operable to provide a facility for a communications session to a mobile node using an internet protocol. When changing affiliation from one of a first and second packet data network to the other of the first and second packet data network, a mobile node is operable to generate a service level identifier representing a requested priority to be afforded to the internet packets communicated to and from the mobile node with respect to other internet packets communicated to and from other nodes. The mobile node is also operable to generate a binding update internet packet providing a care of address of the mobile and an indication of the service level identifier in the binding update internet packet and to communicate the binding update internet data packets to a home agent of the mobile node. The home agent is operable in response to the binding update to identify the service level identifier and to communicate the internet packets in accordance with the requested priority represented by the service level identifier. The telecommunications system can prioritise the transmission of internet packets according to a priority requested by the mobile node represented by the service level identifier thus reducing a likelihood that mobile node will experience delays or interruptions in the transmission of data.

摘要： A packet radio communications system communicates internet packets to and/or from mobile user equipment. The system comprises a core network comprising a plurality of packet data networks, each including network communications elements operable to communicate internet packets using an internet protocol transport plane, and a common gateway support node. The gateway support node is operable to route the internet packets via communications bearers established through the packet data networks using the network communications elements. The system includes a plurality of radio access networks connected by the internet protocol transport plane to the core network components of the packet data networks for communicating the internet protocol packets to and/or from the mobile user equipment. Each of the radio access networks is operable to provide radio access bearers for communicating the internet packets to and/or from the mobile user equipment.

摘要： Apparatus for and methods of enabling a gateway node of a first packet-switched data network to select a first channel for transferring a tunnelled data packet to a destination packet data protocol address of a mobile node provided service in the first network are disclosed. The gateway node is configured to select the first channel from a plurality of channels configured to transfer data packets to the destination packet data protocol address of the mobile node, and the selection is performed by matching a packet data protocol address, associated with a data packet received by the gateway node, to one or more data packet filters associated with the plurality of channels.
