Abstract

In order to enable contents to be shared between participants in group communication when the contents are located in a by a communication server (501), a solution in which a user terminal sets us a transport mechanism between the media server and the communication server for delivering the contents from media server to the communication server so that the contents are not passing through the user terminal (507), and controls delivery of the contents (508), is provided.

Claims

1. A method comprising:

setting up, by an apparatus, at least a first and a second media stream for a contents stored in a media server, said first media stream being between the apparatus and a communication server, and said second media stream being between the communication server and the media server to be used for delivering

the contents in the second media stream from the media server to the communication server; and

controlling the second media stream by the apparatus.

2. A method as claimed in claim 1, wherein the setting up comprises at least the following:

requesting, by the apparatus, from the communication server at least the first and the second media stream;

receiving in the apparatus an acceptance of the first and second media streams from the communication server, said acceptance containing a first address for the media stream in the communication server;

requesting, by the apparatus, the media server to deliver the contents to the communication server by using the first address as a target address in the request;

receiving in the apparatus a response from the media server, said response containing a second address for the media stream in the media server; and

updating the source address of the second media stream to be the second address.

3. A method as claimed in claim 1, further comprising:

using a session description protocol offer answer mechanism between the apparatus and the communication server;

using a real-time streaming protocol between the apparatus and the media server; and

using a real-time transport protocol when delivering the contents.

20. A method as claimed in claim 1, further comprising:

requesting establishment of a further media stream from the communication server to another apparatus; and

sharing the content using the first and the further media stream.

4. An apparatus comprising a processor configured to

set up a transport mechanism between a communication server providing group communication and a media server for contents in the media server;

and

control delivery of the contents between the media server and the communication server.

12. An apparatus as claimed in claim 4, further configured to use during the setting up a first protocol with the communication server and a second protocol with the media server.

22. An apparatus as claimed in claim 4, wherein the apparatus is a user terminal.

5. An apparatus comprising a control unit configured to set up a transport mechanism between a communication server providing group communication and a media server for contents in the media server;

and to control delivery of the contents between the media server and the communication server.

6. An apparatus as claimed in claim 5, wherein the control unit is further configured, during the setting up, to obtain a target address from the communication server and a source address from the media server, and to send the target address to the media server and the source address to the communication server.

7. An apparatus as claimed in claim 5, wherein the control unit is further configured, during the setting up, to request from the communication server at least a first and a second media stream;

to receive an acceptance of the first and second media streams from the communication server, said acceptance containing a first address in the communication server;

to request the media server to deliver contents to the communication server by using the first address as a target address in the request;

to receive a response from the media server, said response containing a second address in the media server; and

to update the source address of the second media stream to be the second address.

8. An apparatus as claimed in claim 5, wherein the control unit is a processor connected to a receiver and a transmitter of the apparatus.

9. An apparatus as claimed in claim 5, wherein the control unit is implemented as containing:

setting up means for setting up a transport mechanism between the media server and the communication server for contents in the media server; and

means for controlling the delivery of the contents between the media server and the communication server.

10. An apparatus as claimed in claim 9, wherein the control unit further contains:

means for obtaining a target address from the communication server and a source address from the media server, the means for obtaining being responsive to the setting up means to perform the obtaining during the setting up, and

means for sending the target address to the media server and the source address to the communication server.

11. An apparatus as claimed in claim 9, wherein the control unit further contains:

means for requesting from the communication server at least a first and a second media stream, the means for requesting being responsive to the setting up means to perform the obtaining during the setting up,

means for receiving an acceptance of the first and second media streams from the communication server, said acceptance containing a first address in the communication server;

means for requesting the media server to deliver contents to the communication server by using the first address as a target address in the request;

means for receiving a response from the media server, said response containing a second address in the media server; and

means for updating the source address of the second media stream to be the second address.

21. An apparatus as claimed in claim 5, further being configured to use during the setting up a first protocol with the communication server and a second protocol with the media server.

23. An apparatus as claimed in claim 5, wherein the apparatus is a user terminal.

14. An apparatus comprising an application server component configured to provide a group communication service and a processor configured to recognize and accept a media stream offer which is not to be forwarded to group members.

13. An apparatus as claimed in claim 14, wherein the processor is configured to implement means for recognizing and accepting a media stream offer which is not to be forwarded to group members.

24. An apparatus as claimed in claim 13, wherein the apparatus is a communication server.

25. An apparatus as claimed in claim 14, wherein the apparatus is a communication server.

15-17. -17. (canceled)

18. A computer-readable medium comprising program instructions, wherein execution of said program instructions causes an apparatus, configured to communicate with a media server containing contents and a communication server providing contents sharing in a group communication, to set up a transport mechanism between the media server and the communication server for the contents and to control delivery of the contents between the media server and the communication server.

19. A computer readable medium as claimed in claim 18, wherein execution of said program instructions causes the apparatus further to request from the communication server at least the first and the second media stream;

to receive an acceptance of the first and second media streams from the communication server, said acceptance containing a first address for the media stream in the communication server;

to request the media server to deliver the contents to the communication server by using the first address as a target address in the request;

to receive a response from the media server, said response containing a second address for the media stream in the media server; and

to update the source address of the second media stream to be the second address.

26. An apparatus configured to obtain contents to be delivered in a media stream, to receive instructions controlling the media stream from an address of an apparatus, and to deliver the contents in the media stream to an address other than the address from which the media stream is controlled.

27. An apparatus as claimed in claim 26, wherein the apparatus is a media server.
