Abstract

A telephone network wherein a subscriber data register (TND) is provided in an exchange (UAT, ZAT) for each subscriber (TN1, TN2) allocated thereto and an intelligent services controller (SCP) is allocated to the originating and/or destination office, whereby a coordinate register (GKR) that contains the geographical coordinates of the subscriber line is additionally provided in the exchange (UAT, ZAT) for each subscriber line (TN1, TN2), and the exchange is configured for fetching the coordinates of the calling or called subscriber from the coordinate register given every outgoing and/or arriving call and for making these coordinates together with the subscriber data and other call data available to an intelligent services controller (SCP) allocated to it and/or for forwarding these in the network for further employment by another exchange and an intelligent services controller allocated to it.

Claims

1. A method for switching telephone connections of a subscriber comprising:

storing subscriber data in an exchange allocated to said subscriber;

administering outgoing and incoming calls with a service control point allocated to said exchange;

storing geographical coordinates for each subscriber serviced by said exchange in a coordinate register in said particular exchange and in a subscriber data register;

calling said geographical coordinates for every call in at least one set of calls selected from the group of call sets consisting of outgoing calls and incoming calls in said exchange; and

transmitting said geographical coordinates to said service control point together with at least said subscriber data; and

wherein further connection sequences in view of said call switching is controlled dependent on said geographical coordinates received by said service control point.

2. The method according to claim 1, wherein said geographical coordinates are compared to geographical comparison coordinates that said service control point stores in lists.

3. The method according to claim 2, wherein modified selection data is conducted from said service control point to said exchange dependent on a result of said comparison.

4. The method according to claim 1, wherein said subscribers are mobile subscribers whose current geographical coordinates are available to said service control point.

5. The method according to claim 1, wherein said subscribers are users of cordless telephones in cells of a cordless system, and wherein said the geographical coordinates of said subscribers are made available to said service control point.

6. The method according to claim 1, wherein said service control point allows connections and excludes connections dependent on said geographical coordinates.

7. The method according to claim 1, wherein said geographical coordinates are forwarded to a destination exchange.

8. The method according to claim 1, wherein said geographical coordinates are forwarded to an originating exchange.

9. The method according to claim 1, wherein a stored announcement is output dependent on said geographical coordinates, and wherein said announcement is output before said connection setup.

10. The method according to claim 1, wherein a call forwarding ensues dependent on said geographical coordinates.

11. The method according to claim 1, wherein said subscriber is connected to an operator dependent on said geographical coordinates.

18. A method according to claim 1, wherein said geographical coordinates are forwarded to a transit exchange.

19. A method according to claim 1, wherein a stored announcement is output dependent on said geographical coordinates, and wherein said announcement is output instead of setting up a connection.

12. A telephone network for switching telephone connections of a subscriber comprising:

a subscriber data register arranged in an exchange for storing subscriber data;

a service control point allocated to said exchange for administration of outgoing and incoming connections;

a coordinate register for storing geographical coordinates for each subscriber serviced by said exchange arranged in said exchange;

said exchange fetching said geographical coordinates for every call in at least one set of calls selected from the group of call sets consisting of outgoing calls and incoming calls and to transmit said geographical coordinates together with at least said subscriber data to said service control point; and

wherein said service control point is configured for controlling further connection sequences in view of a switching of said further connection dependent on received geographical coordinates.

13. A telephone network according to claim 12, wherein said service control point comprises list with comparison geographical coordinates for comparison with said geographical coordinates.

14. A telephone network according to claim 12, wherein said service control point is configured for receiving current geographical coordinates from mobile subscribers.

15. A telephone network according to claim 12, wherein said service control point is configured for receiving geographical coordinates from users of cordless telephones that are located in cells of a cordless system.

16. A telephone network according to claim 12, wherein said exchange is a destination exchange for reception of said geographical coordinates.

17. A telephone network according to claim 12, wherein said exchange is an originating exchange for reception of said geographical coordinates.

20. A telephone network according to claim 12, wherein said exchange is a transit exchange for reception of said geographical coordinates.

21. Telephone network according to one of the claims 14 through 20, characterized in that the intelligent services controller (SCP) is configured for allowing specific connections but not allowing others dependent on the geographical coordinates of a calling and/or called subscriber.

22. Telephone network according to one of the claims 14 through 21, characterized in that each exchange (UAT, ZAT) is configured for forwarding the geographical coordinates of one of its calling subscribers to a destination or, respectively, transit exchange.

23. Telephone network according to one of the claims 14 through 22, characterized in that the intelligent services controller (SCP) and the exchange (UAT, ZAT) are configured for playing a stored announcement dependent on the geographical coordinates of a subscriber (TN1, TN2) before the connection setup or instead of setting up a connection.

24. Telephone network according to one of the claims 14 through 23, characterized in that the intelligent services controller (SCP) and the office (UAT, ZAT) are configured for implementing a call forwarding dependent on the geographical coordinates of a subscriber (TN1, TN2).

25. Telephone network according to one of the claims 14 through 24, characterized in that the intelligent services controller (SCP) and the exchange (UAT, ZAT) are configured for connecting a subscriber to an operator dependent on the geographical coordinates of a subscriber (TN1, TN2).

26. Telephone network according to one of the claims 14 through 25, characterized in that the intelligent services controller (SCP) and the exchange (UAT, ZAT) are configured for activating one or more switching-oriented events of the connection setup such as, for example, ringing at the called subscriber, refusing the call, releasing the call, etc., for the further intelligent services controller dependent on the geographical coordinates of a subscriber (TN1, TN2).
