Abstract

Claims (38)

1. A method for transferring a call between a telecommunications network and a data network, a gateway being arranged between the data network and the telecommunications network, the method comprising:

converting voice data of the call from a format used in the telecommunications network into a format used in the data network;

processing signaling data of the call by a data processing device arranged in the data network, wherein the signaling data is transferred bit-transparently from the gateway to the data processing device and converted by the data processing device into corresponding control commands for the gateway;

transferring the control commands to the gateway for controlling the connection element in the data network, or transferring the control commands from the gateway to the data processing device and the data processing device converting the control commands into corresponding signaling data; and

transferring the signaling data bit-transparently to the gateway for forwarding to the telecommunications network.

2. The method as claimed in claim 1 , wherein status information is transferred over a network element control interface of the gateway to the data processing device.

3. The method as claimed in claim 1 , wherein the signaling data of the call is converted by the data processing device into corresponding control commands for a further gateway, the further gateway being arranged between the data network and at least one telecommunication terminal, and the control commands being transferred to the further gateway for controlling the connection element in the data network, or control commands being transferred from the further gateway to the data processing device and converted by the data processing device into corresponding signaling data, and the signaling data being transferred bit-transparently to the gateway for forwarding to the telecommunications network.

4. The method as claimed in claim 1 , wherein the data in the data network is transferred with the Internet Protocol.

5. A data recessing device of a data network, which is connected to a telecommunications network through a gateway computer, the data processing device comprising:

means for receiving bit-transparently transferred signaling data of a call incoming through the telecommunications network;

means for converting the signaling data into corresponding control commands for the gateway;

means for transferring the control commands to the gateway for controlling the connection element in the data network;

means for receiving control commands from the gateway;

means for converting the control commands into corresponding signaling data; and

means for bit-transparent transfer of the signaling data to the gateway for forwarding to the telecommunications network.

6. The data processing device as claimed in claim 5 , further comprising:

means for converting the signaling data into corresponding control commands for a further gateway, which is arranged between the data network and at least one telecommunication terminal;

means for transferring the control commands to the further gateway for controlling the connection element in the data network;

means for transferring control commands from the further gateway to the data processing device;

means for converting the control commands into corresponding signaling data; and

means for bit-transparent transfer of the signaling data to the gateway for forwarding to the telecommunications network.

7. The data processing device as claimed in claim 5 , wherein the data processing device presents means for compressing and decompressing the signaling data.

8. The processing device as claimed in claim 5 , further comprising:

means for carrying out a method for transferring a call between a telecommunications network and a data network, a gateway being arranged between the data network and the telecommunications network, through which gateway voice data of the call is converted from a format used in the telecommunications network into a format used in the data network, and signaling data of the call being processed by a data processing device arranged in the data network, wherein the signaling data is transferred bit-transparently from the gateway to the data processing device and converted by the data processing device into corresponding control commands for the gateway and the control commands are transferred to the gateway for controlling the connection element in the data network, or control commands are transferred from the gateway to the data processing device and converted by the data processing device into corresponding signaling data, and the signaling data is transferred bit-transparently to the gateway for forwarding to the telecommunications network.

9. A gateway arranged between a telecommunications network and a data network, the gateway comprising:

means for converting voice data of a call from a format used in the telecommunications network into a format used in the data network;

means for bit-transparent transfer of signaling data of the call to a data processing device of the data network;

means for receiving control commands corresponding to the signaling data from the data processing device;

means for executing the control commands for controlling the connection element in the data network;

means for transferring control commands to the data processing device;

means for receiving bit-transparently transferred signaling data corresponding to the control commands; and

means for forwarding the signaling data to the telecommunications network.

10. The gateway as claimed in claim 9 , further comprising means for compressing and decompressing the signaling data.

11. The gateway as claimed in claim 9 , further comprising means for transferring status information across a network element control interface of the gateway to the data processing device.

12. The gateway as claimed in claim 9 , wherein the gateway is connected over an E1 interface with a V5.2 communication channel with the telecommunications network.

13. The gateway as claimed in claim 9 , wherein the gateway is connected over an E1 interface with a D communication channel with the telecommunications network.

14. The gateway as claimed in claim 9 , further comprising:

means for carrying out .a method for transferring a call between a telecommunications network and a data network, a gateway being arranged between the data network and the telecommunications network, through which gateway voice data of the call is converted from a format used in the telecommunications network into a format used in the data network, and signaling data of the call being processed by a data processing device arranged in the data network, wherein the signaling data is transferred bit-transparently from the gateway to the data processing device and converted by the data processing device into corresponding control commands for the gateway and the control commands are transferred to the gateway for controlling the connection element in the data network, or control commands are transferred from the gateway to the data processing device and converted by the data processing device into corresponding signaling data, and the signaling data is transferred bit-transparently to the gateway for forwarding to the telecommunications network.
