Abstract

A method to transfer control is presented. The method includes sending a message requesting transfer of control of a collaborative session, and receiving notification, in response to the sent message, indicative of a transfer result of said requested transfer of control. The method may include, when the transfer result in the received notification indicates success, relinquishing control of the collaborative session. The method may include maintaining control of the collaborative session independent of the transfer result in the received notification. The message requesting transfer of control of a collaborative session may also comprises a request for media transfer.

Claims

1. A method to transfer control, the method comprising:

sending a message requesting transfer of control of a collaborative session; and

receiving notification, in response to the sent message, indicative of a transfer result of said requested transfer of control.

2. The method of claim 1, further comprising:

when the transfer result in the received notification indicates success, relinquishing control of the collaborative session.

3. The method of claim 1, wherein the transfer result in the received notification indicates passive.

4. The method of claim 1, further comprising maintaining control of the collaborative session independent of the transfer result in the received notification.

5. The method of claim 1, wherein the message requesting transfer of control of a collaborative session also comprises a request for media transfer.

6. The method of claim 1, wherein the method to transfer control involves requesting control, and further includes:

receiving a request to activate control of a collaborative session;

determining acceptance of the request to activate control of the collaborative session; and

sending an indication, in response to receiving the activation request, the indication indicative of the determined acceptance.

7. A user equipment, comprising:

a processor, the processor being configured to;

send a message requesting transfer of control of a collaborative session; and

receive a notification, in response to the sent message, indicative of a transfer result of said requested transfer of control.

8. The user equipment of claim 7, wherein the processor is configured to, when the transfer result in the received notification indicates success, relinquish control of the collaborative session.

9. The user equipment of claim 7, wherein the transfer result in the received notification indicates passive.

10. The user equipment of claim 7, wherein the processor is configured to maintain control of the collaborative session independent of the transfer result in the received notification.

11. The user equipment of claim 7, wherein the message requesting transfer of control of a collaborative session also comprises a request for media transfer.

12. The user equipment of claim 7, wherein the processor is configured to request control, and is further configured to:

receive a request to activate control of a collaborative session;

determine acceptance of the request to activate control of the collaborative session; and

send an indication, in response to receiving the activation request, the indication indicative of the determined acceptance.

13. A network node, comprising:

a processor, the processor being configured to;

receive a message requesting transfer of control of a collaborative session; and

transmit a notification, in response to the sent message, indicative of a transfer result of said requested transfer of control.

14. The network node of claim 13, wherein the transfer result in the transmitted notification indicates passive.

15. The network node of claim 13, wherein the message requesting transfer of control of a collaborative session also comprises a request for media transfer.
