Method for transferring control of a conference call

1. A method for transferring control of an existing multi-participant conversation, in which at least two communication terminals are connected to each other through a data connection, to a conference control application, comprising the following steps:

creating of a virtual conference room that serves as an anchor point for the application and can be a virtual participant in the conversation,

switching the conference room into the data connection, and

assigning a master role to the conference room, wherein a signal generated by the application causes the switching of the conference room into the data connection and the assignment of the master role to the conference room;

wherein the master role is assigned to the conference room by transferring the master role of the multi-participant conversation from one of the communication terminals to the virtual conference room via the signal generated by the application simultaneously with the switching of the conference room into the data connection; and

wherein at least three communication terminals are connected to each other in the conversation.

2. The method of claim 1 , wherein the multi-participant conversation is conducted in the form of a system conference.

3. The method of claim 2 , comprising, incorporating, or converting the system conference into an application-controlled conference.

4. The method of claim 3 , comprising changing system-controlled conference channels for the system conference to application-controlled channels for the conference control application.

5. The method of claim 1 , comprising, before switching the conference room into the existing data connection, handing over the conference room to the communication terminal assigned the role of master of the multi-participant conversation using a service operation selected from the group consisting of CorNet-NQ and QSIG Single Step Call Transfer.

6. The method of claim 1 , comprising before the conference room is switched into the existing data connection, sending a call-waiting signal for the conference room to the communication terminal of the multi-participant conversation that was assigned a master role for the multi-participant conversation in under one second.

7. The method of claim 1 , wherein the conference room is switched into the existing data connection using a service operation selected from the group consisting of CSTA Service Conference Call and CSTA Service Join Call.

8. The method of claim 1 , comprising after assigning the master role to the conference room, adding additional communication terminals into the multi-participant conversation with node overlapping.

9. The method of claim 1 , wherein the switching of the conference room into the data connection comprises:

transferring or handing over the conference room to the communication terminal of the existing multi-participant conversation initially assigned the master role;

generating a call-waiting signal for the conference room in the communication terminal of the existing multi-participant conversation initially assigned the master role, the call-waiting signal occurring in less than one second after the transferring or handing over of the conference room; and

switching the conference room into the data connection after the transferring or handling over of the conference room to connect the conference room to all the communication terminals of the multi-participant conversation.

10. The method of claim 1 , comprising:

after the master role is assigned to the conference room and after the conference room is switched into the data connection, incorporating, by the conference room, additional participants into the existing multi-participant conference; and

wherein a trunk is assigned as a proxy to the conference room so that an address of the conference room remains hidden from the communication terminals of the multi-participant conference.

11. The method of claim 1 , wherein the multi-participant conversation is a conference call or a video conference call.

12. A method for transferring control of an existing multi-participant conversation, in which at least two communication terminals are connected to each other through a data connection, to a conference control application, comprising the following steps:

creating of a virtual conference room that serves as an anchor point for the application and can be a virtual participant in the conversation,

switching the conference room into the data connection, and

assigning a master role to the conference room, wherein a signal generated by the application causes the switching of the conference room into the data connection and the assignment of the master role to the conference room; and

wherein the switching of the conference room into the data connection comprises:

switching the conference room directly into the data connection by the communication terminal of the existing multi-participant conversation initially assigned the master role such that the assigning of the master role from the communication terminal of the existing multi-participant conversation initially assigned the master role to the conference room occurs in a single step at a same time as the switching of the conference room into the data connection.

13. The method of claim 12 , wherein at least three communication terminals are connected to each other in the conversation.

14. The method of claim 12 , comprising switching the conference room in a source node of a network in the existing data connection into a target node of the network, and causing a network trunk in the target node to be a proxy for the application.

15. The method of claim 12 , comprising switching the conference room in a source node in the existing data connection to a target node via a single system image in the source node using a service operation.

16. The method of claim 12 , wherein the application is run on a conference server device.

17. The method of claim 12 , wherein the application is run on a conference server computer device.

18. Computer-readable non-transitory storage media having executable code stored thereon that defines a method that is performed when the code is executed by a conference system device, the method comprising:

creating of a virtual conference room that serves as an anchor point for an application and can be a virtual participant in an existing multi-participant conversation in which at least two communication terminals are connected to each other through a data connection;

switching the conference room into the data connection; and

assigning a master role to the conference room, wherein a signal generated by the application causes the switching of the conference room into the data connection and the assignment of the master role to the conference room; and

wherein the master role is assigned to the conference room by transferring the master role of the multi-participant conversation from one of the communication terminals to the virtual conference room via the signal generated by the application simultaneously with the switching of the conference room into the data connection.

19. A server having the computer-readable non-transitory storage media of claim 18 that is configured to execute the executable code.
