Abstract

A telecommunication group is formed by a multiplicity of private telecommunication facilities configured to connect calls between clients services by those facilities and subscribers of those clients based upon facility identification numbers AID and client identification numbers KID determined by dispatcher numbers from E.164 call numbers.

Claims

1. A telecommunications facility for forming a group with at least one other said telecommunications facility and comprising a memory for storing data as to subscribers of clients of said at least one other telecommunications facility capable of utilizing said group of telecommunications facilities together and independently from one another, said data including evaluation-relevant parts of call numbers of each subscriber of said at least one other telecommunications facility capable of utilizing said group of telecommunications facilities together and independently from one another, a facility identification number AID of said at least one other call number is connected, and a client identification number KID of the client of the respective subscriber.

2. The telecommunications facility to which the respective subscriber with the respective facility according to claim 1, further comprising a dispatcher unit for determining a KID and an AID or for determining an AID from a call number of an incoming call.

3. A group of at least two telecommunications facilities interconnected for call transfer between them, at least one of said telephone facilities being as defined in claim 2, said facilities being interconnected for call transfer to subscribers and clients thereof.

4. The group of telecommunications facilities defined in claim 3 wherein at least one of said telecommunications facilities has a client-to-client routing table which, for each client identification number KID permits internal traffic within the group for subscribers assigned to the corresponding client.

5. A method of configuring a group of interconnected telecommunications facilities each having a plurality of clients each with a respective plurality of terminal devices capable of communicating through the group independently of one another, said method comprising the steps, in at least one of said telecommunications facilities, of:

assigning a respective facility identification number AID to each of said facilities in said group;

assigning a client identification number KID to each client in the group;

storing evaluation-relevant parts of E.164 call numbers of subscribers of said one of said facilities and subscribers of other facilities which are required for determination of the AID and KID thereof as dispatcher numbers; and

assigning the AID and KID to the dispatcher numbers.

6. The method defined in claim 5, further comprising the step of creating a client-to-client routing table which, for each client identification number KID permits internal traffic within the group for subscribers assigned to the corresponding client.

7. The method defined in claim 5, further comprising the step, in each of said facilities, of assigning each of said facilities by the respective facility identification number AID to a tie line over which the respective facility can be reached.

8. The method defined in claim 7, further comprising the step of reserving a transmission capacity over a tie line from one facility to another facility of the group for a client based upon the client identification number KID thereof.

9. The method defined in claim 5 wherein both KID and AID are determined for both caller and called for traffic external to a client and the group.

10. The method defined in claim 5 wherein at least one of the further facilities is a conventional extension exchange facility with subscribers of a single client.

11. A method of operating a group of telecommunications facilities which are interconnected by tie lines and which have multiple clients each of which can have a plurality of terminal devices which can use the group independently from one another, said method comprising the steps of:

receiving a call;

determining a client identification number KID singularly assigned to each client from a call number of the call; and

assigning the call to the client identified by the determined client identification number KID.

12. The method defined in claim 11, further comprising the step of determining whether the call derives from a caller belonging to the same client as the called terminal device denominated by said call number.

13. The method defined in claim 11, further comprising the step of determining whether a connection is possible internally of the group between a caller originating the call a called party denominated by said call number.

14. The method defined in claim 11, further comprising the step of deriving a sender KID from an E.164 call number of a sender originating said call or an evaluation-relevant part thereof and a target KID from an E.164 call number of a called party or an evaluation-relevant part thereof.

15. The method defined in claim 11, further comprising the step of determining a facility identification number AID for the facility of the terminal device denominated by said call number from said call number.

16. The method defined in claim 15, further comprising the step of testing whether the AID of the facility denominated by said call number is identical to the AID of a testing facility.

17. The method defined in claim 14 wherein the determination of the KID is effected with dispatcher numbers stored in one of said telecommunication facilities in the form of parts of E.164 call numbers of subscribers of said one of said facilities and which are required for determination of AID and KID from the respective call number.

18. The method defined in claim 14, further comprising charging for traffic internal to the group and external to a client at a tariff individual to the respective client.

19. The method defined in claim 14, further comprising charging for traffic internal to the group and internal to a client at a tariff individual to the respective client.

20. Dispatcher software for identifying a client and a telecommunications facility in a group of telecommunication facilities interconnected by tie lines and based upon a client identification number KID assigned to each of a multiplicity of clients of each telecommunication facility of the group and a telecommunications facility identification number AID assigned to each telecommunications facility of the group, whereby the identification of the client and facility is effected with the aid of dispatch number stored in a dispatcher of one of the telecommunications facilities in a form of parts of E.164 call numbers of associate terminal devices of the group to give an AID and KID from a called number of a terminal device upon receipt of a call.
