Abstract
The invention essentially relates to the configuration of a network element and to a method for processing signalling data and controlling the connection of a speech communication link between at least two communication devices of subscribers in a communication network, whereby said communication devices are associated with different domains. The inventive network element comprises at least one signalling transmission unit for converting data formats from signalling data emerging from a first domain into a data format suitable for transmitting the signaling data to a second domain and at least one media-transmission unit for converting the data format of the useful data arising from the first domain and associated with the speech communication link into a data format suitable for transmitting the user data to the second domain. The signalling transmission unit also comprises communication means for controlling the media-transmission unit by using the information from the signalling data.

14. A network element for processing signaling data and for controlling a connection of a voice communication link between at least two communication devices assigned to different packet-switched communication networks or different domains within a communication network, the network element comprising:
-
a signaling transmission unit for converting the signaling data format of signaling data originating from a first domain into a data format suitable for forwarding the signaling data to a second domain; and
a media transmission unit for converting the media data format of payload data originating from the first domain and associated with the voice communication link into a data format suitable for forwarding the payload data to the second domain, wherein the signaling transmission unit comprises further communication mechanisms for controlling the media transmission unit using the signaling data. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method for processing signaling data and for controlling a connection of a voice communication link between at least two communication devices assigned to different packet-switched communication networks or different domains within a communication network, the method comprising:
-
converting a data format of signaling data originating from a first domain into a data format suitable for forwarding the signaling data to a second domain;
converting the data format of payload data originating from a first domain and associated with the voice communication link into a data format suitable for forwarding the payload data to a second domain; and
forwarding the converted signaling data and payload data to the second domain, wherein converting the data format of the signaling data and converting the data format of the payload data are synchronized by a control system using the signaling data.
