Abstract

Claims (38)

1. A method of facilitating transferring of conference call sessions from a primary communication device, wherein a conference call controller is configured to establish a conference call session with the primary communication device and other communication devices, comprising:

establishing a control session and a media session between the primary communication device and the conference call controller, wherein the media session includes the communication of media data signals;

displaying a user interface on the primary communication device, the user interface including a transfer option;

receiving a command selecting the transfer option;

sending a transfer request from the primary communication device to the conference call controller to link an alternate communication device within the conference call session;

determining whether a predetermined authentication time period has elapsed; and

determining whether the transfer request requires authentication, and if so displaying on the user interface an authentication interface for authentication of the transfer request.

2. The method as claimed in claim 1 , further comprising:

terminating the media session between the primary communication device and the conference call controller; and

maintaining the control session between the primary communication device and the conference call controller subsequent to terminating the media session.

3. The method as claimed in claim 1 , further comprising determining whether the transfer request is authenticated.

4. The method as claimed in claim 1 , further comprising sending a request for authentication from the primary communication device to the conference call controller; and

receiving a confirmation of authentication from the conference call controller.

5. The method as claimed in claim 4 , wherein said sending of the request for authentication comprises requesting a transfer from the primary communication device to the alternate communication device via the conference call controller and receiving a confirmation of authentication from the alternate communication device via the conference call controller.

6. The method as claimed in claim 1 , wherein said displaying of the authentication interface is displayed during the conference call session.

7. The method as claimed in claim 1 , further comprising:

determining that authentication between the primary communication device and the conference call controller is required based on whether the predetermined authentication time period has elapsed.

8. The method as claimed in claim 1 , wherein said sending comprises Session Initiation Protocol (SIP) based commands.

9. A communication device, comprising:

a communication subsystem for communicating with a conference call controller, wherein the conference call controller is configured to establish a conference call session with the communication device and other communication devices including establishing a control session and a media session between the communication device and the conference call controller, wherein the media session includes the communication of media data signals;

and

a display for displaying a user interface on the communication device, the user interface including a transfer option,

wherein the communication device is configured for:

receiving a command selecting the transfer option,

sending a transfer request from the communication device to the conference call controller to link an alternate communication device within the conference call session,

determining whether a predetermined authentication time period has elapsed; and

determining whether the transfer request requires authentication, and if so displaying on the user interface an authentication interface for authentication of the transfer request.

10. The communication device as claimed in claim 9 , wherein the communication device is further configured for:

terminating the media session between the communication device and the conference call controller; and

maintaining the control session between the communication device and the conference call controller subsequent to terminating the media session.

11. The communication device as claimed in claim 9 , wherein the communication device is further configured for determining whether the transfer request is authenticated.

12. The communication device as claimed in claim 9 , wherein the communication device is further configured for sending a request for authentication from the communication device to the conference call controller; and

receiving a confirmation of authentication from the conference call controller.

13. The communication device as claimed in claim 12 , wherein said sending of the request for authentication comprises requesting a transfer to the alternate communication device via the conference call controller and receiving a confirmation of authentication from the alternate communication device via the conference call controller.

14. The communication device as claimed in claim 9 , wherein said displaying of the authentication interface is displayed during the conference call session.

15. The communication device as claimed in claim 9 , wherein the communication device is further configured for:

determining that authentication between the communication device and the conference call controller is required based on whether the predetermined authentication time period has elapsed.

16. The communication device as claimed in claim 9 , wherein said sending comprises Session Initiation Protocol (SIP) based commands.
