Method for on-demand teleconferencing
First Claim
1. A conferencing method for setting up an on-demand conference call for a subscriber in a telecommunication system, said on-demand conference call having a conference size for a plurality of users, the method comprising the steps of:
- assigning a unique number for the on-demand conference call;
delivering the assigned number to the plurality of users, receiving a request based on the assigned number and the conference size from the telecommunication system in a conference allocation and control system (CACS) connected to a plurality of bridge servers, the CACS located externally to the telecommunication system, each of said plurality of bridge servers having a plurality of ports, each of said plurality of bridge servers having sufficient ports to support a plurality of on demand conference calls;
selecting in the CACS available ports for the conference size on one of said plurality of said bridge servers so as to dynamically allocate the selected ports to the on-demand conference call;
setting up the on-demand conference call in the telecommunications system on said selected ports on the one selected bridge server under control of the CACS;
connecting the plurality of users to the set-up on-demand conference call when each of the plurality of users dials the assigned number into the telecommunication system;
informing the subscriber over the telecommunication system when ports are not available for the on-demand conference call.

Abstract
An on-demand teleconferencing system and method for setting up an on-demand conference call in a telecommunications system having the Advanced Information Network (AIN) architecture with system signaling the number 7 (SS7) and a Public Switched Telephone Network (PSTN). A subscriber is assigned an on-demand conference call number. When that number is dialed into the PSTN, it is identified by the PSTN that the dialed number requires handling by the SS7. The SS7 links the dialed number to a conference allocation and control system (CACS) which is connected to a plurality of scalable bridge servers. The CACS selects bridge servers available to handle the conference call and based upon a selection criteria such as a peak load sets up the on-demand conference call in one of the selected bridge servers.
