Abstract

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for collaboration conferencing with multiple participants over a communications network, and more specifically for a conferencing routing service for managing and routing collaboration participants. In one embodiment, the conferencing system may utilize Session Initiation Protocol (SIP) to conduct the routing of the collaboration conferences within the telecommunications network. The SIP-based routing provides for the exchanging of information from one device of the conferencing system to another that is not available in non-IP based conferencing systems. Thus, through the use of IP-based telecommunication devices, the network provides beneficial features for collaboration conferencing.

Claims

1. A telecommunications network comprising:

at least one conference bridge; and

at least one routing device configured to;

receive a communication from a user of the telecommunications network, the communication comprising a request to initiate a collaboration conference;

identify the at least one conference bridge; and

transmit a Session Initiation Protocol (SIP) refer command configured to route the communication from the user to the at least one conference bridge;

wherein, the at least one conference bridge is a SIP-based telecommunications device and is configured to host the collaboration conference in response to the communication from the user.

2. The telecommunications network of claim 1 wherein the at least one routing device is further configured to:

transmit a SIP-based request message to the at least one conference bridge, wherein the SIP-based request message comprises at least a request for an open communication port of the at least one conference bridge.

3. The telecommunications network of claim 2 wherein the at least one conference bridge is further configured to

transmit an acknowledgement message from the at least one conference bridge in response to the request message, the acknowledgement message comprising at least the Internet Protocol (IP) address of the at least one conference bridge.

4. The telecommunications network of claim 3 wherein the refer command is a SIP-based transmission message comprising at least the Internet Protocol (IP) address of the at least one conference bridge.

5. The telecommunications network of claim 1 wherein the routing device comprises:

a network interface unit for receiving the communication from a user of the telecommunications network; and

an application server configured to execute an application to transmit the refer command configured to route the communication from the user to the at least one conference bridge.

6. The telecommunications network of claim 2 wherein the communication from the user of the telecommunications network further comprises an identification of the user and the routing device is further configured to:

associating a conference identification number with the identification of the user of the communication request; and

wherein the SIP-based request message to the at least one conference bridge further comprises the conference identification number.

7. The telecommunications network of claim 6 wherein the identification comprises a text string unique to the user of the telecommunications network.

8. The telecommunications network of claim 6 wherein the collaboration conference comprises a web-based conference component and an audio component and the SIP-based request message to the at least one conference bridge further comprises a request for an audio communication port and an IP communication port.

9. A method for hosting a collaboration conference in a telecommunications network comprising:

receiving a SIP request message for access to a collaboration conference from a requester'"'"'s communication device, the request comprising an identifier of the requester in the header of the SIP request message;

selecting a hosting conference bridge from a plurality of conference bridges associated with the telecommunications network and configured to host a collaboration conference, wherein the hosting conference bridge is a session initiation protocol (SIP) based telecommunication device;

transmitting a SIP request message to the selected hosting conference bridge, wherein the SIP-based request message comprises at least the conference identification number; and

transmitting one or more SIP refer routing messages to the telecommunications network, wherein the one or more routing messages comprise at least an internet protocol (IP) address of the selected hosting conference bridge.

10. The method of claim 9 further comprising:

receiving a SIP-based acknowledgement message from the selected hosting conference bridge in response to the SIP-based request message, the acknowledgement message comprising at least the IP address of the selected conference bridge.

11. The method of claim 9 further comprising

associating a conference identification number with the identification of the user of the communication request;

and

wherein the SIP-based request message to the at least one conference bridge further comprises the conference identification number.

12. The method of claim 11 wherein the identification comprises a text string unique to the requester of the telecommunications network.

13. The method of claim 11 wherein the identification comprises a telephone number of the requester'"'"'s communication device unique and an access code number.

14. The method of claim 9 further comprising:

transmitting a SIP-request command requesting operational information of the plurality of conference bridges, the operational information comprising at least the available capacity for the plurality of conference bridges.

15. The method of claim 9 wherein the SIP based conference bridge is configured to provide high definition audio and high definition video capabilities for the collaboration conference.

16. The method of claim 9 further comprising:

receiving a SIP-reinvite command comprising at least the identifier of the requester, the SIP-reinvite command configured to switch the requester from a first collaboration conference to a second collaboration conference.

17. A system for hosting a collaboration conference in a telecommunications network, the system comprising:

a network interface unit configured to receive a communication from a user of a communications network to establish a collaboration conference on the network;

an application server in communication with the network interface unit; and

a computer-readable medium connected to the application server configured to store information and instructions that, when executed by the application server, performs the operations of;

receiving a session initiation protocol (SIP) request message from a routing device of the network, the SIP request message comprising a request for at least one communication port of a hosting conference bridge associated with the network, wherein the hosting conference bridge is a SIP based telecommunication device;

reserving at least one communication port of the hosting conference bridge;

transmitting a SIP-based acknowledgement message in response to the SIP request message, the acknowledgement message comprising at least the IP address of the hosting conference bridge;

receiving a SIP refer message; and

hosting a collaboration conference of a plurality of users of the network.

18. The system of claim 17 wherein the communication port is a video communication port configured to transmit video packets through the network.

19. The system of claim 17 wherein the communication port is a web-based communication port configured to transmit internet protocol (IP) data packets through the network.

20. The system of claim 17 wherein the SIP request message from the routing device comprises an identifier of the requester'"'"'s communication device in a header portion of the SIP request message from the routing device.
