  • Publication number: 20120134351
    Abstract: The application relates to SMS over LTE radio access. Several alternatives are already known, such as specified in 3GPP TS 24.247 which supports text messaging capabilities and 3GPP 23.204 which supports all existing SMS capabilities through SMS encapsulation in IP. Furthermore, 3GPP 23.272 which relates to SMS in CS fallback. A further technique is known as Generic Access Network which is under study in 3GPP 23.879 relating to CS domain services over evolved PS access and in Voice Over LTE VOLGA. The present application provides a solution for handling messages between legacy networks in the form of circuit-switched networks and IP network architecture in the form of an IP Multimedia Subsystem IMS while minimizing the efforts needed for system integration by maximal reuse of existing functionalities.

  • Publication number: 20110274011
    Abstract: The invention refers to a method for supporting a data service provisioning, a device adapted thereto, and a corresponding computer program product. The method comprises the steps of receiving a service request for the data service, receiving a time range requirement in relation to the requested data service, wherein said time range requirement indicates a time range, in which the requested data service is to be provided, and selecting an access network that can provide the data service in the given time range.

  • Patent number: 7764623
    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 analyzed 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: 20100047863
    Abstract: The present invention provides a polynucleotide or a pair of polynucleotides encoding an enzyme having nitrile hydratase (NHase) [E.C. 4.2.1.84] activity. Furthermore, a vector and a host comprising the disclosed polynucleotide or pair of polynucleotides and methods for the production of the same are provided. Moreover, the invention relates to a pair of polypeptides or a fusion protein having NHase activity, an antibody specifically binding to the pair of polypeptides or fusion protein, a primer or probe, which specifically hybridizes under stringent conditions to the disclosed polynucleotide or either one of the pair of polynucleotides, a composition comprising the polynucleotide or pair of polynucleotides, the pair of polypeptides or fusion protein, the antibody and/or one or more primers or probes of the invention and a method for the production of amides comprising the enantioselective conversion of nitrites.

  • 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: 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.
