Abstract

The invention provides an on-demand real-time video conefrencing system in a circuit switched communications network. The on-demand real-time video conferencing system includes at least one video conference control system that receives an on-demand request for a video conference from a user and, in real-time, allocates video conferencing resources and connects the user with at least one other video conference participant through the circuit switched communications network. Each of the at least one video conference control system includes a video conference connection unit and a voice response unit. The video conference connection unit includes a plurality of video ports coupled to the circuit switched communications network. The video conference control system connects the user with the at least one other video conference participant based on the number of total video conference participants, the number of video ports available in the at least one video conference control system and the available connection paths in the circuit switched communications network.

6. The on-demand real-time video conferencing system of claim 5, wherein the selected meeting reservation controller transfers the on-demand request received from the user to the another one of the at least one video conference control system when transferring the call from the user.

7. The on-demand real-time video conferencing system of claim 5, wherein if no other one of the at least one video conference control system has the first number of video ports connectable to the at least one other video conference participant, then the selected meeting reservation controller informs the user that the video conference cannot be provided and ends the call from the user.

8.

9. The on-demand real-time video conferencing system of claim 8, wherein if no other one of the at least one video conference control system has the third number of video ports so that the second number plus the third number of video ports connect to the at least one other video conference participant, then the selected meeting reservation controller informs the user that the video conference cannot be provided and ends the call from the user.

10. The on-demand real-time video conferencing system of claim 3, wherein the on-demand request from the user further includes:

at least one of a user identification number and a password, if the at least one of the user identification number and the password is incorrect, then the meeting reservation controller ending the call from the user.

11. The on-demand real-time video conferencing system of claim 3, wherein the on-demand request from the user further includes:

billing information, the billing information indicating at least one of the user paying a cost of the video conference and each video conference participant paying for a portion of the cost of the video conference, the meeting reservation controller billing the cost of the video conference based on the billing information.

12. The on-demand real-time video conferencing system of claim 2, wherein the voice response unit comprises:

a voice recognition device, the voice recognition device converting words spoken by the user into messages received by the meeting reservation controller.

13. The on-demand real-time video conferencing system of claim 2, wherein the selected one of the at least one video conference control system is selected based on at least one of availability of video ports of each of the at least one video conference control system and availability of connection paths in the circuit switched communications network.
