Abstract

A communication network having a meet-me conference bridge is disclosed. The conference is accessed by each conferee dialing a code assigned to the bridge. A conference host is given a special code which accesses the same bridge but identifies the host as the controller who can add on other conferees and perform other special functions.

Claims

1. For use in a communication network having a conference arrangement, a plurality of customer stations, and switching means for interconnecting said customer stations with said conference arrangement to form a conference, said conference arrangement comprising

a conference bridge having a plurality of ports each being connectable to a corresponding one of said stations,

receiver means effective when coupled to one of said stations for controlling said conference, and

coupling means responsive to the receipt of a first code from a calling one of said stations for coupling said calling station to said bridge and responsive to the receipt of a second code from another of said stations for coupling said other station to said bridge and to said receiver means.

2. The arrangement of claim 1 wherein said coupling means comprises means for ascertaining if said receiver means is connected to any of said stations coupled to said bridge before connecting said receiver means to said other station.

3. The arrangement of claim 1 wherein said receiver means comprises means operable to receive signals from said other station for transmittal to said coupling means, and wherein said coupling means includes means responsive to signals from said receiver means for coupling still other of said stations to said bridge.

4. For use in a communication network having a meet-me conference arrangement, a plurality of customer stations, and switching means for interconnecting said customer stations with said conference arrangement to form a conference, said conference arrangement comprising

a conference bridge having a plurality of conference ports each connectable to a corresponding one of said stations,

receiver means effective when coupled to one of said stations for controlling said conference, and

coupling means responsive to the receipt of a first code from a first calling one of said stations for coupling said first calling station to a first one of said ports independent of said receiver means and responsive to the receipt of a second code from a second calling one of said stations for coupling said second station to said receiver means and to a second one of said ports.

5. The arrangement of claim 4 wherein said receiver means comprises means operable to receive signals from said customer stations for transmittal to said coupling means, and wherein said coupling means includes means responsive to signals from said receiver means for coupling other ones of said stations to said bridge.

6. For use in a communication system having a conference arrangement, a plurality of customer stations, and switching means for interconnecting said customer stations with said conference arrangement to form a conference, said conference arrangement comprising

a time-slot interchange connected to said switching means,

a conference bridge having a plurality of ports each connected to said time-slot interchange;

a signal receiver system having a plurality of signal receivers each connected to said time-slot interchange, and

a processor connected to said switching means and operable for controlling said time-slot interchange,

said processor responsive to a first code received from a first one of said customer stations for causing said time-slot interchange to interconnect said first one of said stations with one of said ports and responsive to a second code received from a second one of said stations for causing said time-slot interchange to interconnect said second one of said stations with one of said signal receivers and another of said ports, and

said one of said signal receivers comprising means responsive to coded signals transmitted from said second customer station for signaling said processor to add other customer stations to said bridge.

7. For use in a communication network having a plurality of conference bridges, a plurality of customer stations, and switching means for interconnecting said stations with said bridges to form a conference, a method for providing customer control of a meet-me conference comprising the steps of:

initiating meet-me conference calls from said customer stations by transmitting from each customer station a bridge location code and an access code,

routing the calls to the bridge identified by the bridge location code,

transmitting the access code to the identified bridge,

identifying the access code transmitted for each call routed to the bridge,

detecting when a host access code is received from a station for coupling the station to the bridge and to receiver apparatus for controlling the conference, and

detecting when a conferee access code is received from other ones of said stations for coupling said other stations to the bridge independent of said receiver apparatus.

8. The method of claim 7 wherein the step of detecting when a host access code is received comprises the step of ascertaining when certain of said stations have each transmitted the host access code and connecting the receiver apparatus to only one of said certain stations transmitting the host access code.
