Method and apparatus for requesting media replication in a collaborative communication session, and method and apparatus for assigning a communication medium for a collaborative communication session
View Patent ↗In a method for requesting media replication in a collaborative communication session, a message is sent which specifies that a communication medium for a collaborative communication session, which is currently being transmitted to at least one terminal, should additionally be transmitted to at least one other terminal, with the at least one other terminal being indicated in the message as the recipient of the communication medium. In a method for assigning a communication medium for a collaborative communication session, a corresponding message is received, and the communication medium is assigned to the at least one other terminal as the recipient of the communication medium. The methods are carried out by appropriately designed apparatuses.
1. One or more non-transitory computer-readable media comprising instructions to cause an internet protocol multimedia subsystem (IMS) server in a collaborative communication session, upon execution of the instructions by the IMS server, to:
identify, based on a message received from a controlled user equipment (UE) that is controlled by a control terminal that has a control role in the collaborative communication session, an identification of a second UE to which a media portion of the collaborative communication session is to be replicated; and
replicate, based on the received message, the media portion of the collaborative communication session to the second UE.
2. The one or more non-transitory computer-readable media of claim 1 , wherein the message is a session initiation protocol (SIP) message.
3. The one or more non-transitory computer-readable media of claim 2 , wherein the message is a SIP REFER message.
4. The one or more non-transitory computer-readable media of claim 1 , wherein the controlled UE is a computer or a mobile telephone.
5. The one or more non-transitory computer-readable media of claim 1 , wherein the media portion includes an audio media portion, a video media portion, or a text media portion.
6. The one or more non-transitory computer-readable media of claim 1 , wherein the instructions are further to cause the IMS server to:
copy the media portion; and
distribute the copied media portion to the controlled UE and the second UE.
7. The one or more non-transitory computer-readable media of claim 1 , wherein instructions are further to cause the IMS server to transmit a direct communication indication to a third UE, the direct communication indication operable to cause the third UE to transmit the media directly to the second UE.
8. A method comprising:
identifying, by an internet protocol multimedia subsystem (IMS) server in a collaborative communication session, based on a message received from a controlled user equipment (UE) that is controlled by a control terminal that has a control role in the collaborative communication session, an identification of a second UE to which a media portion of the collaborative communication session is to be replicated; and
replicating, by the IMS server based on the received message, the media portion of the collaborative communication session to the second UE.
9. The method of claim 8 , wherein the message is a session initiation protocol (SIP) message.
10. The method of claim 9 , wherein the message is a SIP REFER message.
11. The method of claim 8 , further comprising:
copying, by the IMS server, the media portion; and
distributing, by the IMS server, the copied media portion to the controlled UE and the second UE.
12. The method of claim 8 , further comprising transmitting, by the IMS server, a direct communication indication to a third UE, the direct communication indication operable to cause the third UE to transmit the media directly to the second UE.
13. An internet protocol multimedia subsystem (IMS) server in a collaborative communication session, the IMS server comprising:
receiver circuitry to:
receive, from a first user equipment (UE) in the collaborative communication session when the first UE is a controlled UE in the collaborative communication session, a first message that includes an identification of a second UE to which a media portion of the collaborative communication session is to be replicated;
receive, from the first UE after replication of the media portion of the collaborative communication session to the second UE, a third message related to a request for information regarding the collaborative communication session, wherein the third message is based on an identification by the first UE that the media portion of the collaborative communication session is to be replicated to the first UE; and
receive, based on the third message, a fourth message that includes an identification of the first UE; and
transmit circuitry coupled with the receiver circuitry, the transmit circuitry to transmit to the first UE, based on the first message, a second message that includes an indication that the media portion of the collaborative communication session is replicated to the second UE.
14. The IMS server of claim 13 , wherein the first message, second message, third message, and fourth message are session initiation protocol (SIP) messages.
15. The IMS server of claim 14 , wherein the first message is a SIP REFER message.
16. The IMS server of claim 14 , wherein the second message is a SIP re-INVITE message.
17. The IMS server of claim 14 , wherein the third message is a SIP SUBSCRIBE message.
18. The IMS server of claim 14 , wherein the fourth message is a SIP REFER message.
19. The IMS server of claim 13 , wherein the IMS server is an IMS application server (AS).
20. The IMS server of claim 13 , wherein the first UE or the second UE is a computer or a mobile telephone.
