Abstract

A method for controlling communication between a number of first terminal modules connected to a multimedia IP network in particular with the first communication session being a call session already running, includes the steps of establishing a first communication session between the first terminal modules, establishing at least one second communication session between at least a subset of the first terminal modules, and storing relation information relating the first and the second communication sessions.

Claims

1. A method for controlling communication between a number of first terminal modules connected to a multimedia IP network, comprising the steps of:

establishing a first communication session between the first terminal modules;

establishing a second communication session between at least a subset of the first terminal modules; and

storing relation information relating the first and the second communication sessions.

2. The method recited in claim 1, wherein the step of establishing the second communication session is performed while said first communication session already exists.

3. The method recited in claim 1, wherein a request signal is transmitted into the multimedia IP network by one of the first terminal modules For initiating the steps of establishing the second communication session and of storing the relation information.

4. The method recited in claim 1, wherein a request signal is transmitted into the multimedia IP network by a second terminal module not part of the first communication session for initiating the steps of establishing the second communication session and of storing the relation information.

5. The method recited in claim 1, wherein a request signal is transmitted into the multimedia IP network by one of the first terminal modules for simultaneously initiating the steps of establishing the first and second communication sessions and of storing the relation information.

6. The method recited in claim 5, wherein the request signal is a call request to a predefined address.

7. The method recited in claim 5, wherein the request signal comprises information on the type of the first and second communication sessions to be initiated.

8. The method recited in claim 1, wherein said first communication session is a call session enabling a voice connection between the first terminal modules.

9. The method recited in claim 8, wherein said call session is a conference call session enabling a simultaneous voice connection between at least three terminal modules.

10. The method recited in claim 1, wherein the step of establishing the second communication session between the first terminal modules comprises:

selecting an application server adapted to control the second communication session and transmitting an invocation request to the selected application server.

11. The method recited in claim 10, wherein the step of selecting an application server comprises the step of analyzing a request signal, which comprises information on a type of the second communication session.

12. The method recited in claim 1, further comprising the step of terminating at least one of the first and second communication sessions, wherein at least one other of the first and second communication sessions is automatically terminated depending on the stored relation information.

13. The method recited in claim 1, wherein the first terminal modules include phone devices adapted to transmit and receive voice information and to transmit a request signal into the multimedia IP network during an established voice connection.

14. A call control application server for use in a multimedia IP network, comprising:

a call session storage device for storing information related to a call session between at least two terminal modules connected to the multimedia IP network;

an inquiry interface for receiving inquiries requesting information stored in said call session storage device; and

an inquiry analysis device for processing a received inquiry and accessing said call session storage device for providing the requested information.

15. A Multimedia IP network system adapted to perform a method for controlling communication between a number of first terminal modules connected to a multimedia IP network, the system comprising:

a first application server adapted to control a first communication session between a number of terminal modules connected to the network system;

at least one second application server adapted to control a second communication session between at least a subset of said terminal modules;

a session storage device for storing information on the first and second communication sessions; and

a relation storage device for storing information relating the first and the second communication sessions.

16. The network system recited in claim 15, wherein the first application server includes a call control application server comprising:

a call session storage device for storing information related to a call session between at least two terminal modules connected to the multimedia IP network;

an inquiry interface for receiving inquiries requesting information stored in said call session storage device; and

an inquiry analysis device for processing a received inquiry and accessing said call session storage device for providing the requested information.

17. The network system recited in claim 15 wherein at least one of the first and second application servers is adapted to terminate at least one of the first and second communication sessions in response to termination of a related communication session.
