Abstract

A telecommunication system for establishing a conference call between various participants to the call communicating via multimedia communication devices. A call participant identification system detects the presence of voice signals made from a speaking call participant during the conference call. Call participant identification information is associated with the voice signals generated by the speaking call participant. A visual indication identifying the call participant is established at other multimedia communication devices connected with the call to identify the speaking call participant to the other participants of the conference call upon the detection of the voice signals from the speaking call participant.

Claims

1. A method for identifying a call participant to a conference call having a plurality of call participants communicating via a telecommunication system, comprising the steps of:

detecting a presence of voice signals during the conference call;

associating call participant identification information with the voice signals in response to the detection of the voice signals;

preselecting a threshold level for silence suppression;

measuring a volume of voice signals received at a communication device associated with the call participant generating the voice signals; and

determining if the volume of voice signals exceeds the threshold level for silence suppression.

2. The method of claim 1 including the steps of storing call participant identification information associated with at least one call participant to the conference call, and

coordinating the call participant identification information with the voice signals generated from the call participant.

3. The method of claim 2 including the step of enabling a visual indication identifying the call participant to be established at the communication device to the conference call in response to the detection of voice signals from the call participant.

4. The method of claim 3 in which the communication device is a multimedia communication device associated with another call participant to the conference call different from the call participant generating the detected voice signals.

5. The method of claim 4 including the step of coupling together a plurality of multimedia communication devices to the conference call in which the multimedia communication devices have a visual display for displaying call participant identification information.

6. The method of claim 5 in which the call participant identification information includes at least one of:

a) video of the call participant,

b) photographic image of the call participant, and

c) data identifying the call participant.

7. The method of claim 4 including the step of determining if the multimedia communication device is an integrated multimedia communication device capable of performing mixing of voice signals with associated data and video signals.

8. The method of claim 1 including the steps of providing a visual suppression of call participant identification information at a different multimedia communication device other than the communication device receiving the voice signals to identify at the different communication device the call participant generating the voice signals in response to the volume of voice signals exceeding the threshold for silence suppression.

9. The method of claim 8 including the step of removing the visual indication of call participant identification information at the different multimedia communication device in response to a determination that the volume of voice signals measured does not exceed the threshold level for silence suppression.

10. In a telecommunication system for establishing a conference call between a plurality of call participants communicating via multimedia communication devices, the improvement being a call participant identification system comprising:

means for detecting a presence of voice signals received at a multimedia communication device during the conference call;

a storage device for storing call participant identification information corresponding to a particular call participant of the conference call;

means responsive to the detection of voice signals during the conference call for associating the call participant identification information of the call participant generating the voice signals with the detected voice signal;

a multipoint control unit that measures a volume of voice signals received at the multimedia communication device; and

means for determining if the volume of voice signals exceeds a preselected threshold level for silence suppression.

11. The telecommunication system of claim 10 including means for enabling a visual indication identifying the call participant generating the voice signals to be established at another multimedia communication device to the conference call.

12. The telecommunication system of claim 11 in which the visual indication includes at least one of:

a) video of the call participant;

b) photographic image of the call participant,

c) data identifying the call participant.

13. The telecommunication system of claim 11 including a conference coordination system for coordinating the call participant identification information with the voice signals generated from the call participant.

14. The telecommunication system of claim 13 including a multipoint control unit coupled with the multimedia communication devices for mixing streams of voice signals from the plurality of multimedia communication devices.

15. The telecommunication system of claim 11 in which said visual indication at the other multimedia communication device identifying the call participant generating the voice signals is established in response to the volume of voice signals exceeding the preselected threshold level.

16. The telecommunication system of claim 15 including means for removing the visual indication identifying the call participant in response to the volume of measured voice signals failing to exceed the preselected threshold level.
