Embodiment Construction

[0039] will now be based on Figure 1 to Figure 3 An embodiment of the method according to the invention is described.

[0040] This embodiment supports the management of VoIP teleconferencing and is implemented in an RTP-based system comprising a UMTS network 11, a teleconferencing server 12 comprising an RTP mixer 15 connected to the network 11, and a plurality of terminals 13. The terminal 13 is able to connect to the teleconferencing server 12 through the UMTS network 11 using the RTP tunnel 14 . The system usually works with figure 1 The system shown corresponds, which has already been described above.

[0041] To establish a VoIP conference call in this system, Session Initiation Protocol (SIP) is used as the signaling protocol. SIP is used together with the Session Description Protocol (SDP) to send an invitation to the called party and to agree on a voice codec, etc. The user of the terminal 13 also initiates a session by sending a SIP request message to the telec...

Abstract

The invention relates to a method for managing packet-switched centralized teleconferencing between a plurality of terminals (13). In order to increase the user's comfort, it is proposed that the method consists of receiving data packets from all terminals (13) on the teleconferencing server (12). Then, based on these data packets, at least one terminal currently providing voice data is determined (13). In a next step, the data received in the data packets are mixed and the mixed data are inserted into a new data packet together with at least one identifier associated with a terminal (13) that has been determined to provide voice data. Terminal to distinguish at least one identifier from other information in the data packet. Finally, the new data packet is sent to the terminal participating in the conference call (13). The invention also relates to a corresponding server and a corresponding terminal.

Description

technical field [0001] The invention relates to a method of managing a packet-switched centralized teleconference between a plurality of terminals. The invention also relates to a conference call server comprising means for managing a centralized conference call and a terminal comprising means for participating in a centralized conference call. Background technique [0002] In a conference call, a group of end users are interconnected in such a way that when one participating user speaks, all other participating users can hear the speaking participant. In such communications, typically only one participating user speaks at a time, while the other users listen. In a centralized conference call, the terminals of participating users are not directly connected to each other, but through a conference call server. Centralized teleconferencing can be implemented through Voice over Internet Protocol (VoIP) teleconferencing applications in the Internet or as voice conferencing in t...
