Abstract

The present invention relates to a method, system, client device, conference server device and computer program product of controlling media composition in a multi-party conversation involving a central control point (50). At a participant (10) of said multi-party conversation, a scope information (SoM) which specifies members of said multi-party conversation is selected and added to a session modifying request. The session modifying request is transmitted to the central control point (50) which initiates a media modification at the specified members in response to the scope information (SoM). Thereby, a client can control whether media modification is applied to the whole conference, selected participants or only between the client itself and the conference server.

Claims

1. A method comprising:

receiving scope information at a client device participating in a multi-party conversation session, wherein the scope information identifies one or more parties participating in the multi-party conversation session for whom a modification of a media type is to be applied;

generating, by the client device, a session modifying request based on the scope information; and

determining, by the client device, to transmit the session modifying request from the client device to a central control point to apply the modification of the media type identified by the scope information.

2. The method of claim 1, wherein the scope information is a header parameter or an attribute of the session modifying request.

3. The method of claim 1, wherein the media type comprises push to talk over cellular (PoC) audio, instant messaging, full-duplex audio, full-duplex video, or some combination thereof.

4. The method of claim 1, wherein the scope information is specified within the session modifying request as a session description protocol (SDP) attribute.

5. The method of claim 1, wherein the scope information is specified within the session modifying request as an a-line value.

6. The method of claim 1, wherein the modification of the media type is applied only between the client device and the central control point without affecting other parties of the multi-party conversation session.

7. The method of claim 1, comprising adding a list of addresses of all parties to whom the modification of the media type is to be applied.

8. The method of claim 7, wherein the list of addresses includes a session initiation protocol (SIP) uniform resource indicator (URI) list.

9. The method of claim 7, wherein the list of addresses includes at least one uniform resource indicator (URI) of the session initiation protocol (SIP).

10. The method of claim 1, wherein the session modifying request is a re-INVITE request of a session initiation protocol (SIP).

11. The method of claim 1, wherein the session modifying request identifies a recipient to contact a third party using the scope information.

12. The method of claim 11, wherein the session modifying request includes a header parameter used to inform the central control point that an existing dialog is to be modified, instead of creating a new dialog.

13. The method of claim 12, wherein the session modifying request includes a callee capability information which indicates in which way the existing dialog is to be modified.

14. The method of claim 11, wherein the scope information is added as an address list.

15. The method of claim 14, wherein the address list comprises at least one uniform resource indicator (URI) of a session initiation protocol (SIP).

16. An apparatus comprising:

at least one processor; and

at least one memory including computer program code;

wherein the at least one memory and the computer program code are configured to, with the at least one processor, direct the apparatus to perform at least the following;

receive scope information at the apparatus while the apparatus is participating in a multi-party conversation session, wherein the scope information identifies one or more parties participating in the multi-party conversation session for whom a modification of a media type is to be applied;

generate a session modifying request based on the scope information; and

determine to transmit the session modifying request from the apparatus to a central control point to apply the modification of the media type identified by the scope information.

17. The apparatus of claim 16, wherein the scope information is a header parameter or a message attribute of the session modifying request.

18. The apparatus of claim 17, wherein the message attribute is a session initiation protocol (SIP) attribute, and the scope information is added as an a-line value.

19. A tangible non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions, which when executed by one or more processors, direct an apparatus to:

receive scope information corresponding to a multi-party conversation session, wherein the scope information identifies one or more parties participating in the multi-party conversation session for whom a modification of a media type is to be applied;

generate a session modifying request based on the scope information; and

determine to transmit the session modifying request to a central control point to apply the modification of the media type identified by the scope information.

20. The computer-readable storage medium of claim 19, wherein the apparatus is directed to provide a user agent for a client device.
