Abstract

A method and system for industry and group-specific calling within a telecommunication system. The method of the present invention includes the steps of receiving, in a carrier network, a call initiated by dialing a group number from a caller terminal; accessing a database in the carrier network to determine an announcement corresponding to the group number; providing the announcement to the caller terminal to prompt a caller to select one of the group members associated with the dialed group number; interpreting a selection command received from the caller to determine a member number of a selected group member; establishing a connection between the network and a member terminal corresponding to the selected member number; and connecting the call from the caller terminal to the selected member terminal. The caller may terminate the connection between the network and the member terminal, and select a connection to other group members, without dialing any additional numbers. Information such as the selection sequence, connect time, and call status may be transmitted by the carrier network to each member terminal prior to connection to the caller terminal.

Claims

1. A method of processing a call in a telecommunication system, comprising the steps of:

receiving a group call initiated by a caller dialing a group number from a caller terminal, wherein the group number is assigned to a group including a plurality of members having distinct member numbers;

receiving a sequence of selection commands entered by the caller during the group call, the selection commands indicating the particular group members selected by the caller;

interpreting the selection commands received from said caller to determine the corresponding member numbers of the selected group members;

connecting said group call from said caller terminal in accordance with the selection command sequence to selected member terminals corresponding to the member numbers of the selected group members; and

transmitting call data, the call data regarding a connection of the group call to one of the selected member terminals, to another of said selected member terminals to which said group call is subsequently connected.

2. The method of claim 1 further including the additional steps of:

terminating a connection of said group call to one of said selected member terminals in response to a termination command from said caller; and

providing an announcement to said caller terminal to prompt said caller to select another one of said plurality of group members associated with said dialed group number.

3. The method of claim 2 wherein said additional steps are repeated until said group call is terminated in response to a disconnect signal received from said caller terminal.

4. The method of claim 1 wherein said group members are different companies within an industry.

5. The method of claim 1 wherein said group number is established by a network provider.

6. The method of claim 1 wherein said group number is an 800 number.

7. The method of claim 1 further including the steps of:

accessing a network database to determine an announcement corresponding to said dialed group number; and

providing said announcement to said caller terminal to prompt said caller to select one of said plurality of group members corresponding to said dialed group number.

8. The method of claim 1 further including the steps of:

storing said call data in a network data register; and

formatting said call data stored in said data register into a data packet suitable for transmission.

9. The method of claim 1 wherein said call data includes an amount of time for which said connection of said group call to said one of the selected member terminals was maintained.

10. The method of claim 1 wherein said call data includes an indication that said one of the member terminals was busy when said connection of said group call to said one of the selected member terminals was made.

11. The method of claim 1 wherein said call data includes an indication that said group call was answered by a group member corresponding to said one of the selected member terminals.

12. The method of claim 1 wherein said call data includes a total connection time for which said group call has been maintained.

13. The method of claim 1 further including the step of accessing a local exchange carrier database prior to establishing a connection between said caller terminal and a network, in order to determine to which of several networks said caller terminal should be connected.

14. The method of claim 1 wherein said step of receiving said group call further includes the steps of:

accessing a network database to determine an internal routing number indicative of subsequent processing of said group call; and

routing said group call to a network adjunct unit in response to said internal routing number, said network adjunct unit receiving and interpreting said selection commands from said caller.

15. An apparatus for processing a call in a telecommunication system, comprising:

a first switch for receiving a group call initiated by a caller dialing a group number from a caller terminal, wherein the group number is assigned to a group including a plurality of members having distinct member numbers;

an adjunct unit for receiving said group call from said first switch;

a detector in said adjunct unit for interpreting a sequence of selection commands entered by the caller and received from said caller terminal, the selection commands indicating the particular group members selected by the caller

a second switch for establishing connections in accordance with the selection command sequence between said first switch and selected member terminals corresponding to the member numbers of the selected group members; and

means for transmitting call data, the call data regarding a connection of the group call to one of the selected member terminals, to another of said selected member terminals to which said group call is subsequently connected.

16. The apparatus of claim 15 further including means for terminating said connection between said first switch and said one of said selected member terminals in response to a termination command from said caller, while said group call is maintained, to thereby permit said caller to select another member of said group.

17. The apparatus of claim 15 wherein said group members are different companies within an industry.

18. The apparatus of claim 15 further including:

a network data register for storing said call data; and

means for formatting said call data stored in said data register into a data packet suitable for transmission.

19. The apparatus of claim 15 wherein said call data includes an indication that said one of the member terminals was busy when said connection of said group call to said one of the selected member terminals was made.

20. The apparatus of claim 15 wherein said call data includes a total connection time for which said group call has been maintained.

21. A method of processing a call in a telecommunication system, comprising the steps of:

receiving a group call initiated by a caller dialing a group number from a caller terminal;

providing an announcement to said caller terminal to prompt said caller to select one of a plurality of group members corresponding to said group number;

interpreting a selection command received from said caller to determine a member number of a selected group member;

connecting said group call from said caller terminal to said member terminal;

storing call data regarding said connection of said group call to said member terminal of said selected group member; and

transmitting said call data to a member terminal of a group member subsequently selected by said caller during said group call.

22. The method of claim 21 wherein said call data includes an amount of time for which said connection of said group call to said member terminal of said selected group member was maintained.

23. The method of claim 21 wherein said call data includes an indication that said member terminal of said selected group member was busy when said connection of said group call to said member terminal of said selected group member was made.

24. The method of claim 21 wherein said call data includes an indication that said selected group member answered said call from said caller after said connection of said group call to said member terminal of said selected group member was made.

25. The method of claim 21 wherein said call data includes a total connection time for which said group call has been maintained.

26. An apparatus for processing a call in a telecommunication system, comprising:

a first switch for receiving a group call initiated by a caller dialing a group number from a caller terminal;

an adjunct unit for receiving said call from said switch, and

for prompting said caller to select one of a plurality of group members associated with said dialed group number;

a detector in said adjunct unit for interpreting a selection command received from said caller terminal indicating a selection of a group member;

a second switch for establishing a connection of said group call to a member terminal corresponding to a selected member number stored in a database;

means for storing call data regarding said connection to said member terminal of said selected group member; and

means for transmitting said call data to a member terminal of a group member subsequently selected by said caller during said group call.
