Abstract: 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.

Abstract: The present invention is directed to a method, a switching server, a terminal device and system for providing circuit switched calls and services to terminal devices connected to a switching server via an IP Multimedia Subsystem. The method comprises a step of providing (S120) a first interworking entity (330) in the terminal device (300) for interworking between circuit switched signalling messages and signalling messages related to packet switched sessions towards the IMS (30). The method further comprises providing (S130) a second interworking entity (230) in the switching server (200) towards the IMS (30). The terminal device (300) is thus capable of accessing circuit switched calls and services directly from the switching server (200).

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.

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.
