Abstract

A communication system comprises a signaling processor and an interworking unit. The signaling processor receives and processes signaling for a call to select a connection and a first bandwidth rate. The signaling processor transfers a first message indicating the connection and the first bandwidth rate. The interworking unit receives the first message and user communications for the call, and in response, transfers the user communications over the connection at the first bandwidth rate. The interworking unit detects a trigger in the user communications, and in response, transfers the user communications over the connection at a second bandwidth rate.

Claims

1. A method of operating a communication system comprising a signaling processor and an interworking unit, the method comprising:

in the signaling processor, receiving and processing signaling for a call to select a connection and a first bandwidth rate and transferring a first message to the interworking unit indicating the connection and the first bandwidth rate;

in the interworking unit, receiving the first message and user communications for the call, and in response, transferring the user communications over the connection at the first bandwidth rate;

in the interworking unit, detecting a trigger in the user communications, and in response, transferring the user communications over the connection at a second bandwidth rate and transferring a second message to the signaling processor indicating the second bandwidth rate; and

in the signaling processor, selecting a billing rate for the call based on the second message.

2. The method of claim 1 wherein selecting the first bandwidth rate comprises processing a caller number to select the first bandwidth rate.

3. The method of claim 1 wherein the trigger comprises a tone.

4. The method of claim 1 wherein the user communications comprise voice communications.

5. The method of claim 1 wherein the first bandwidth rate is lower than the second bandwidth rate.

6. The method of claim 1 wherein the connection comprises a virtual connection.

7. The method of claim 1 wherein the connection comprises an asynchronous transfer mode connection.

8. The method of claim 1 wherein the signaling comprises signaling system seven signaling.

9. A communication system comprising:

a signaling processor configured to receive and process signaling for a call to select a connection and a first bandwidth rate and to transfer a first message indicating the connection and the first bandwidth rate;

an interworking unit configured to receive the first message and user communications for the call, and in response, to transfer the user communications over the connection at the first bandwidth rate;

the interworking unit is further configured to detect a trigger in the user communications, and in response, to transfer the user communications over the connection at a second bandwidth rate and to transfer a second message to the signaling processor indicating the second bandwidth rate; and

the signaling processor is further configured to select a billing rate for the call based on the second message.

10. The communication system of claim 9 wherein the signaling processor is configured to process a caller number to select the first bandwidth rate.

11. The communication system of claim 9 wherein the trigger comprises a tone.

12. The communication system of claim 9 wherein the user communications comprise voice communications.

13. The communication system of claim 9 wherein the first bandwidth rate is lower than the second bandwidth rate.

14. The communication system of claim 9 wherein the connection comprises a virtual connection.

15. The communication system of claim 9 wherein the connection comprises an asynchronous transfer mode connection.

16. The communication system of claim 9 wherein the signaling comprises signaling system seven signaling.
