  • Publication number: 20090124254
    Abstract: The invention relates to a method and devices for supporting the use of a dual mode mobile station in a cellular telecommunications network connected to a first cellular telecommunications access network and a second short range and/or high bandwidth access network. The node connecting the second access network and the core network imitates a node of the cellular telecommunications access network towards a core network and operates towards the second access network like a SIP proxy.

  • Publication number: 20090097402
    Abstract: To enhance quality of service management in support of application sessions running on top of bearer services, according to the present invention it is suggested to, firstly, execute a bearer service analysis in support of automatic quality of service class management. Heretofore, a bearer service carrying packet switched service traffic in support of an application session is analysed for identification of different types of services by the application session. Related analysis information derived at an analysis unit 10 is then forwarded to a quality of service management unit 16, which is adapted to automatic quality of service class management. In particular, the quality of service management unit 16 determines and manages a quality of service class according to the identified quality of service class as forwarded by the bearer service analysis unit 10.

  • Publication number: 20090070484
    Abstract: The invention relates to a technique for selecting a framing format to be used for communications on the user plane of a layered communications network. The selection technique includes the provision of a first user plane component (such as a media gateway, MGW) bridging transmission regimes and operable in accordance with two or more different framing formats. The first user plane component is controllable via control messages received from a control plane without being responsive to any framing format instructions possibly included in the control messages. The first user plane component or any other user plane equipment in communication with the first user plane component selects the framing format to be used for user plane communications. The selected framing format is then implemented by the first user plane component for communications with a second user plane component.
