Abstract

In an embodiment, a method for changing a collaborative communications session may be provided. The method may include: sending a request message requesting for authorizing a change of a collaborative communications session to an end device of the collaborative communications session; determining whether an authorization message is received from the end device in response to the request message sent; and changing the collaborative communications session, in case it is determined that an authorization message is received from the end device in response to the request message sent.

Claims

1. A method for changing a collaborative communications session, the method comprising:

sending a request message requesting authorization for a change of a collaborative communications session to an end device of the collaborative communications session;

determining whether an authorization message is received from the end device in response to the request message sent; and

changing the collaborative communications session, in case it is determined that an authorization message is received from the end device in response to the request message sent.

2. The method of claim 1,

wherein at least one of the request message and the authorization message is a message in accordance with a call control protocol.

3. The method of claim 2,

wherein the call control protocol comprises at least one protocol selected from a list of protocols consisting of:

Session Initiation Protocol SIP;

Real-Time Control Protocol RTCP;

Hyper Text Transport Protocol http;

File Transfer Protocol FTP;

Simple Mail Transfer Protocol SMTP; and

XML Configuration Access Protocol XCAP.

4. The method of claim 1,

wherein the request message is at least one of a SIP NOTIFY message and a SIP INFO message.

5. The method of claim 1,

wherein the authorization message is at least one of a SIP REFER message and a SIP INFO message.

6. The method of claim 1,

wherein sending the request message requesting authorization for the change of the collaborative communications session to the end device of the collaborative communications session is performed based on a subscription of the end device for notifications about collaborative communications session change requests.

7. A method for authorizing a change of a collaborative communications session, the method comprising:

receiving a request message requesting authorization for a change of a collaborative communications session from a call managing server of the collaborative communications session;

determining whether the requested change is to be authorized; and

sending an authorization message to the call managing server, in case it is determined that the requested change is to be authorized.

8. The method of claim 7,

wherein at least one of the request message and the authorization message is a message in accordance with a call control protocol.

9. The method of claim 8,

wherein the call control protocol comprises at least one protocol selected from a list of protocols consisting of:

Session Initiation Protocol SIP;

Real-Time Control Protocol RTCP;

Hyper Text Transport Protocol http;

File Transfer Protocol FTP;

Simple Mail Transfer Protocol SMTP; and

XML Configuration Access Protocol XCAP.

10. The method of claim 7,

wherein the request message is at least one of a SIP NOTIFY message and a SIP INFO message.

11. The method of claim 7,

wherein the authorization message is at least one of a SIP REFER message and a SIP INFO message.

12. The method of claim 7,

wherein receiving the request message requesting authorization for the change of the collaborative communications session from the call managing server of the collaborative communications session is performed by an end device of the collaborative communications session based on a subscription of the end device for notifications about collaborative communications session change requests.

13. A call managing server comprising:

a sender circuit configured to send a request message requesting authorization for a change of a collaborative communications session to an end device of a collaborative communications session;

a determination circuit configured to determine whether an authorization message is received from the end device in response to the request message sent; and

a changing circuit configured to change the collaborative communications session, in case it is determined that an authorization message is received from the end device in response to the request message sent.

14. The call managing server of claim 13,

wherein at least one of the request message and the authorization message is a message in accordance with a call control protocol.

15. The call managing server of claim 14,

wherein the call control protocol comprises at least one protocol selected from a list of protocols consisting of:

Session Initiation Protocol SIP;

Real-Time Control Protocol RTCP;

Hyper Text Transport Protocol http;

File Transfer Protocol FTP;

Simple Mail Transfer Protocol SMTP; and

XML Configuration Access Protocol XCAP.

16. The call managing server of claim 13,

wherein the request message is at least one of a SIP NOTIFY message and a SIP INFO message.

17. The call managing server of claim 13,

wherein the authorization message is at least one of a SIP REFER message and a SIP INFO message.

18. The call managing server of claim 13,

wherein the sender circuit is further configured to send the request message requesting authorization for the change of the collaborative communications session to the end device of the collaborative communications session based on a subscription of the end device for notifications about collaborative communications session change requests.

19. An end device for authorizing a change of a collaborative communications session, the end device comprising:

a receiver circuit configured to receive a request message requesting authorization for a change of a collaborative communications session from a call managing server of the collaborative communications session;

a determination circuit configured to determine whether the requested change is to be authorized; and

a sender circuit configured to sending an authorization message to the call managing server, in case it is determined that the requested change is to be authorized.

20. The end device of claim 19,

wherein at least one of the request message and the authorization message is a message in accordance with a call control protocol.

21. The end device of claim 20,

wherein the call control protocol comprises at least one protocol selected from a list of protocols consisting of:

Session Initiation Protocol SIP;

Real-Time Control Protocol RTCP;

Hyper Text Transport Protocol http;

File Transfer Protocol FTP;

Simple Mail Transfer Protocol SMTP; and

XML Configuration Access Protocol XCAP.

22. The end device of claim 19,

wherein the request message is at least one of a SIP NOTIFY message and a SIP INFO message.

23. The end device of claim 19,

wherein the authorization message is at least one of a SIP REFER message and a SIP INFO message.

24. The end device of claim 19,

wherein the receiver circuit is configured to receive the request message requesting authorization for the change of the collaborative communications session from the call managing server of the collaborative communications session based on a subscription of the end device for notifications about collaborative communications session change requests.

25. A method for changing a collaborative communications session, the method comprising:

changing a collaborative communications session, in case it is determined that an authorization message is received from an end device in response to a sent request message requesting authorization of a change of a collaborative communications session.
