Communication system having conference server

1. A communication system comprising a conference server device, a conference control unit, a plurality of moderator units, and a plurality of telecommunication devices, wherein:

the conference server provides at least one conference for the plurality of telecommunication devices,

each of the plurality of telecommunication devices has a message generation unit for generating a communication request message and a transmission device for transmitting the communication request message to the conference server device,

the conference server device has a receiver device for receiving the communication request messages, a message generation unit for generating a notification message if a communication request message has been received, and a transmission device for transmitting notification messages to all of the moderator units,

each of the plurality of moderator units has a receiver device for receiving the notification messages, a message generation unit for generating a communication right decision message based on all of the notification messages, and a transmission device for transmitting the communication right decision message to the conference server device,

the plurality of moderator units each decide, independently of one another, which telecommunication device is to be granted a communication right and informs the conference server device of these communication right individual decisions,

the conference control unit automatically combines the communication right individual decisions of the plurality of moderator units to form an overall decision which specifies which telecommunication device is granted a communication right, and

the communication right is granted to only a single telecommunication device within a conference as the right to transmit a data stream for a chosen communication medium.

2. The communication system as claimed in claim 1 , wherein the communication system is configured in accordance with a 3GPP standard.

3. The communication system as claimed in claim 1 , wherein the communication system is configured in accordance with the UMTS standard.

4. The communication system as claimed in one of claims 1 , wherein each of the moderator units decides on the allocation of communication rights anonymously.

5. The communication system as claimed in claim 1 , further comprising a communication right allocation device controlling the allocation of communication rights in accordance with the overall decision.

6. The communication system as claimed in one of claims 1 , further comprising a communication right allocation unit allocating a communication right according to a rule base.

7. The communication system as claimed in claim 1 , wherein the communication system is set up such that a communication right is respectively allocated for different communication means.

8. The communication system as claimed in claim 1 , further comprising at least one higher-instance moderator unit which is coupled to the conference control unit and is set up such that, if the conference control unit cannot ascertain an unambiguous overall decision, the higher-instance moderator unit uses the communication right individual decisions to make an unambiguous overall decision which unambiguously specifies which telecommunication device is granted a communication right.

9. A method of controlling a conference in a communication system having a conference server device, a conference control unit, a plurality of moderator units, and a plurality of telecommunication devices, the method comprising:

the conference server device providing at least one conference for the plurality of telecommunication devices;

each of the plurality of telecommunication devices generating a communication request message and transmitting the communication request message to the conference server device;

the conference server device receiving the communication request messages, generating a notification message if a communication request message has been received, and transmitting notification messages to all of the moderator units;

each of the plurality of moderator units receiving notification messages, generating a communication right decision message based on all of the notification messages, and transmitting the communication right decision message to the conference server device;

the plurality of moderator units each deciding, independently of one another, which telecommunication device is to be granted a communication right and informing the conference server device of these communication right individual decisions;

the conference control unit automatically combining the communication right individual decisions of the plurality of moderator units to form an overall decision which specifies which telecommunication device is granted a communication right; and

the communication right only ever being granted to one single telecommunication device within a conference as the right to transmit a data stream for a chosen communication medium.

10. A telecommunication conference control unit comprising:

a reception unit receiving communication right individual decision messages from a plurality of moderator units, each of which messages contains a proposal for an allocation of a communication right;

a decision unit that automatically makes an overall decision on the allocation of a communication right to a telecommunication device based on the communication right individual decision messages; and

a message generation unit that generates an overall decision message in accordance with the overall decision,

wherein the communication right is granted to only one single telecommunication device within a conference as a right to transmit a data stream for a chosen communication medium.

11. A method of controlling the allocation of communication rights, the method comprising:

receiving communication right individual decision messages from a plurality of moderator units, each of which messages contains a proposal for the allocation of a communication right;

automatically making an overall decision on the allocation of a communication right to a telecommunication device based on the communication right individual decision messages; and

a message generation unit generating an overall decision message in accordance with the overall decision,

wherein the communication right is granted to only one single telecommunication device within a conference as a right to transmit a data stream for a chosen communication medium.

12. A telecommunication conference control unit comprising:

means for receiving communication right individual decision messages from a plurality of moderator units, each of which messages contains a proposal for the allocation of a communication right;

means for automatically making an overall decision on the allocation of a communication right to a telecommunication device based on the communication right individual decision messages; and

a message generation means for generating an overall decision message in accordance with the overall decision,

wherein the communication right is granted to only one single telecommunication device within a conference as a right to transmit a data stream for a chosen communication medium.
