Abstract

A telephone switching office having a plurality of meet-me conference bridging systems is disclosed. An access code is assigned to each conference, and at an agreed upon time, all conferees for a conference dial the same access code. The switching office allocates a bridging system in response to the first call to arrive at the office. In the event more than one call for the same conference arrives at the host office concurrently, the processing of all but one call is delayed until an idle bridging system is connected to that one call. The delayed calls, and any future calls to the conference are then steered to the same bridging system.

Claims

1. For use in a communication network comprising a plurality of customer stations, a plurality of meet-me conference systems, communication channels and switching means for selectively interconnecting said stations to said conference systems via said communication channels, apparatus for controlling the interconnection of said stations to said conference systems comprising:

means responsive to a request for conference service from one of said stations for designating an access code for a conference,

means responsive to the initial receipt of said access code from a particular one of said stations for selecting an idle one of said conference systems and for requesting connection of said particular station to said selected system, and

means effective upon the successful connection of said particular station to said selected conference system for designating a group of said communication channels for connecting to said selected conference system other of said stations transmitting said access code.

2. The invention defined in claim 1 wherein said means for selecting and for requesting includes means for blocking the connection of said other stations to a conference system other than said selected one.

3. The invention defined in claim 1 wherein said means for selecting and for requesting includes means for postponing the connecting of said other stations to said selected conference system until said particular station is connected to said selected conference system.

4. The invention defined in claim 3 wherein said means for selecting and for requesting comprises a memory associated with said conference and wherein said means for postponing the connecting of said other stations comprises means for changing the status of said conference in said memory to a hold state.

5. For use in a communication network comprising a plurality of customer stations, a plurality of conference systems, communication channels and switching means for selectively interconnecting said stations to said conference systems via said communication channels, a method for controlling the interconnection of said stations to said conference systems comprising the steps of

assigning an access code to a conference upon the receipt of a request from one of the stations for conferencing service,

selecting an idle one of said conference systems in response to the receipt of the access code from a first calling one of said stations,

interconnecting said first calling station with said selected conference system over one of said communication channels, and

designating a particular group of said communication channels for interconnecting said selected conference system with other ones of said stations transmitting said access code.

6. The invention defined in claim 5 further comprising the step of temporarily suspending the interconnecting of said stations transmitting said access code with said selected conference system while said first calling station is being connected to said selected conference system.

7. For use in a communication network comprising a plurality of customer stations, a plurality of meet-me conference systems, communication channels and switching means for selectively interconnecting said stations to said conference systems via said communication channels, apparatus for controlling the interconnection of said stations to a conference system comprising:

means responsive to a request for conference service from one of said stations for assigning an access code to a conference,

means responsive to the receipt of said access code from a first calling one of said stations for selecting an idle one of said conference systems,

means effective upon the selection of said idle conference system for establishing a first connection between said selected conference system and said first calling station, and

means for blocking the interconnection to any of said conference systems of other calling stations transmitting said access code during the establishment of said first connection.

8. The invention defined in claim 7 also including means effective upon the connection of said first calling station to said selected conference system for interconnecting said other calling stations to said selected conference system.

9. The invention defined in claim 8 wherein each of said conference systems is accessible via a corresponding subgroup of communication channels,

wherein said means for establishing a first connection comprises means for designating the subgroup which corresponds to said selected conference system for connection to said other calling stations, and

wherein means are provided for blocking any station transmitting said access code from interconnection to subgroups other than said designated subgroup.

10. For use in a communications network comprising a plurality of customer stations, a plurality of meet-me conference systems, communication channels and switching means for selectively interconnecting said stations with said conference systems via said communication channels, a method of establishing a conference comprising the following steps:

assigning an access code to a conference,

informing designated of said stations to be included in the conference of the access code,

transmitting the access code to the switching means from each of said designated stations requesting connection to the conference, and

in response to a plurality of concurrently received requests bearing the access code, selecting only one of said requests for call processing and blocking all other requests during the call processing of the selected request.

11. The invention defined in claim 10 further comprising the steps of processing the call associated with the selected request by connecting the station making the request over a communication channel to a selected idle one of said conference systems, and unblocking the other requests bearing the access code by connecting the stations associated therewith to said selected idle conference system.
