Abstract: The invention proposes several methods for codec handling. In specific, methods involving providing a supported codec list of a Call Control Server are described. A node receives information, whether a terminal supports a wideband codec, wherein the information is received in call set up signaling from the terminal of the subscriber. Furthermore, configuration information is retrieved, whether a Radio Access Node supports the wideband codec. Additionally, information is retrieved, whether a media gateway supports the wideband codec, wherein the information is either provided by the operator or retrieved from the media gateway (MGW1, MGW2, MGWx). The information is analyzed and in response to the analysis a supported codec list is provided. Furthermore, alternative embodiments and devices adapted for the methods are disclosed.

Abstract: A routing system transfers data packets of real time communication services of a call, and includes a converter receiving media gateway control protocol encoded first control data and processing the first control data to obtain second control data. The system, based on the first control data, allocates a first transport address for a first routing port for incoming data packets, and allocates a second transport address for a second routing port for outgoing data packets. A central control entity controls a central control entity controlled network of forwarding elements, and determines a static pathway through the network of forwarding elements based on the second control data. A first end of the static pathway corresponds to the first routing port and a second end corresponds to the second routing port. The central control entity controls a data plane flow of a stream of the data packets along the static pathway.

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 proposes a solution for providing IMS services to users having circuit-switched controlled terminals. In particular, it is proposed, in order to allow IMS to take the full call and service control, to combine circuit-switched and packet-based multimedia functionality in a new node type called Mobile Access Gateway Control Function (MAGCF). In particular the present invention provides a method for ensuring that the MAGCF node acts as a roaming anchor point in order to enforce the handling of originating and terminating calls in the IMS.

Abstract: A method of interworking CS (Circuit Switched) video calls with video calls using IP multimedia protocols is provided. According to the method, an interworking function receives signalling comprising an indication of the codec capability of a CS terminal involved in the CS video call, as part of a MONA (Media Oriented Negotiation Acceleration) negotiation. Thereafter IP codec negotiation is initiated. And thereafter the MONA negotiation is continued and/or completed. Thus the codec capabilities and/or preferences of the CS terminal can be taken into account during the IP codec negotiation with the IP endpoint.

Abstract translation: 提供了一种使用IP多媒体协议与CS（电路交换）视频通话与视频通话互通的方法。 根据该方法，作为MONA（面向对象协商加速）协商的一部分，互通功能接收包括CS视频呼叫中涉及的CS终端的编解码能力指示的信令。 此后启动IP编解码器协商。 此后，MONA谈判将继续和/或完成。 因此，在与IP端点的IP编解码器协商期间可以考虑CS终端的编解码器能力和/或偏好。
