Abstract

A communications network having a dial-up conference arrangement is disclosed. The conference host can summon an operator and cause the conference details to be displayed at an operator position. The detailed information presented to the operator permits the operator to identify conferees independently of the directory number that was used to dial-up the conferee. This permits the operator to redial dropped legs, transfer control of the conference and perform other functions with respect to the identified conferee.

Claims

1. For use in a communication system having a plurality of stations, a conference bridge and means for interconnecting said stations to said bridge for conferencing, a method of controlling stations connected to the bridge comprising the steps of

summoning an operator position in response to a request from said bridge,

transmitting to said operator position a data message containing the directory number of and the status of all stations originally connected to the bridge.

identifying at said operator position one of said stations independently of the directory numbers transmitted thereto, and

transmitting a message to said bridge from said operator position to control the one identified station.

4. The method set forth in claim 1 or 2 wherein the step of transmitting said message includes the step of transmitting indicia unique to each said station.

5. The method set forth in claim 1 or 2 wherein the step of identifying one of said stations comprises the step of establishing a voice connection between said operator position and said one station independent of any other stations connected to said bridge.

6. The method set forth in claim 1 or 2 further comprising the step of visually displaying the contents of said data message at said operator position and wherein the step of identifying said one station includes the step of indicating on said visual display a predetermined status unique to said one station.

2. For use in a communication system having a plurality of stations, a conference bridge and means for interconnecting said stations to said bridge for conferencing, a method for controlling the connection of said stations to the bridge comprising the steps of

detecting the disconnection of one of said stations from the bridge,

transmitting to a remote operator position in response to said detection a data message containing the directory number of and the status of all stations originally connected to the bridge,

identifying at said operator position said one station independently of the directory number transmitted thereto, and

transmitting a control message from the operator position to the bridge to effect thereat the reconnection of the disconnected one of said stations.

3. The method set forth in claim 2 wherein the step of detecting the disconnect of said station includes the step of informing another station connected to said bridge of said disconnection, causing said other station to establish an audio connection to said operator position, and transmitting an announcement of said conference identity over said audio connection.

7. For use in a communication system having a plurality customer stations, a conference bridge and means for interconnecting said stations to said bridge for conferencing, a method for controlling the connection of said stations to the bridge comprising the steps of

detecting when one of said stations has disconnected from the bridge,

informing at least another of said stations still connected to said bridge that said one station has disconnected,

having said other station summon an operator at a remote operator position,

transmitting to said remote position a data message containing the directory number of each station originally connected to the bridge and whether each said station is currently disconnected from the bridge,

displaying the contents of the data message on a video display terminal at the operator position, and

generating at said position a first control signal for transmittal to said bridge by positioning the terminal cursor to the display representing said one station.

8. The invention defined in claim 7 wherein the step of transmitting said first control signal includes the step of alerting said one station.

9. The invention defined in claim 8 further comprising the step of coupling together said operator position and said one station in response to an answer signal from said one station.

10. The invention defined in claim 9 further comprising the step of generating a second control signal for transmittal to said bridge to cause said bridge to reconnect said one station to said bridge.

11. The invention defined in claim 10 wherein the step of generating said control signals includes the step of identifying said one station as indicated by the position of a cursor on said terminal display and operating a function key individually associated with the particular control signal generated.

12. For use in a communication system having a plurality customer stations, a conference bridge and means for interconnecting said stations to said bridge for conferencing, a method for controlling the connection of said stations to the bridge comprising the steps of

causing said bridge to summon an operator at a remote operator position,

transmitting to said remote position a data message containing the directory number of each station originally connected to the bridge and whether each said station is currently disconnected from the bridge,

displaying the contents of the data message on a video display terminal at the operator position, and

generating at said position one of a plurality of control signals for transmittal to said bridge by positioning the terminal cursor to the display representing said one station.

13. The invention defined in claim 12 wherein the step of generating one of said control signals comprises the step of identifying said one station as indicated by the position of a cursor on said terminal display and operating a selected one of a plurality of function keys individually associated with one of the particular control signals generated.

14. The invention defined in claim 13 further including the step of initiating a call to said identified station in response to one of said control signals.

15. The invention defined in claim 13 further including the step of disconnecting said identified station from said conference in response to one of said control signals.

16. The invention defined in claim 13 further including the step of coupling said identified station with said operator position exclusive of said conference bridge in response to one of said control signals.

17. The invention defined in claim 12 further including the step of putting the bridge under the control of said identified station in response to one of said control signals.
