摘要:
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.
摘要:
A call to a dual mode user equipment is handled by using a further access network from cellular telecommunications access network. An indication of an incoming call to the user equipment is received in a control node that the device can be reached via a device using session initiation protocol (SIP) via the cellular telecommunication access network. The device using SIP sends messages to a device that transforms messages sent according to call control signaling protocol used in the cellular telecommunications network into messages according to SIP. A route to the SIP device is linked to a device that transforms user plane according to protocol in the cellular telecommunications access network into user plane according to internet protocol and vice versa.

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. This is achieved by an entity (100) which adapts messages received from the IMS (50) in such a way that the appear to a controller entity (200) providing conventional short message functionalities as if they have been received from a mobile terminal accessing a radio access network through a radio network interface of a circuit-switched network (40).

摘要:
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.
摘要:
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.

摘要:
A communication network is described, comprising: —an access network, —a switching control network comprising call control entities arranged for association with subscribers, where said access network is arranged for routing signalling of a given subscriber to a call control entity associated with said given subscriber, and—an Internet Protocol based network for providing a set of services centred in said Internet Protocol based network to one or more of said subscribers, wherein said switching control network comprises a group of first call control entities and a group of second call control entities, said first call control entities are arranged for providing call control services to subscribers having circuit switched subscriptions, and said second call control entities are arranged for providing a gateway to connect to said Internet Protocol based network for subscribers having subscriptions to said set of services centred in said Internet Protocol based network, and each first call control entity has a subscriber association redirector for redirecting an association of a subscriber associated with said each first call control entity and having a subscription to said services centred in said Internet Protocol based network to said group of second call control entities.
