US 8169937 B2Abstract
The invention relates to a method for managing a packet switched, centralized conference call between a plurality of terminals 13. In order to enable an enhancement of the user comfort, it is proposed that the method comprises at a conference call server 12 receiving data packets from all terminals 13. Based on these data packets, then at least one terminal 13 currently providing voice data is determined. In a next step, the data received in the data packets is mixed, and the mixed data is inserted into new data packets together with at least one identifier associated to one of the terminals 13 which were determined to provide voice data, such that the at least one identifier can be distinguished from any other information in the data packets. Finally, the new data packets are transmitted to terminals 13 participating in the conference call. The invention relates equally to a, corresponding server and to a corresponding terminal
This application is a Continuation of U.S. patent application Ser. No. 10/613,986 filed Jul. 3, 2003, which claims priority from PCT Application No. PCT/IB2002/002625 filed Jul. 4, 2002, both of which are incorporated herein by reference in their entirety.
In addition, the terminals 13 determine all those SSRC identifiers in the CSRC list which are listed before the SSRC identifier associated to the conference call server 12. The names which were determined for those SSRC identifiers belong to currently active participants and are pointed out in the presented list 32 on the display 31. In the example of FIG. 3, a special speaker indicator icon 33 is employed for indicating the participants who are currently speaking. In the presented situation, only one participant is currently talking, and a speaker indicator icon 33 is located next to the corresponding name, “Salmi”, in the list 32.
