Abstract

A system and method for automatically and seamlessly routing telephone calls across a telephone network. The system includes a telephone network interface box having a computer, a master file and client file stored in the computer. The master file is dynamically linked to the client file at routing time to produce a selected client location telephone number which is transmitted across the telephone network. The system utilizes Automatic Number Identification to identify the calling party. The master file has a plurality of records having a telephone number and a spatial key and is updated frequently. The client file has a plurality of records having a spatial key and a client telephone number. Methods of generating client file records for both radius and polygon defined service areas through an automated computer process are included in the present invention. Another embodiment of the system merges the records of the client file with the records of the master table to generate a single table to create a one table system. The one table system increases speed of the call routing process. A second embodiment of the one table system is provided by a special case of the client file build process which yields a caller telephone number to service location telephone number file. A further embodiment provides real-time processing in situations where high call volumes and transaction processing speed are not a major issue. The real-time processing system is simple to update and requires minimal storage.

Claims

1. A method of automatically generating a telephone number to telephone number (TNTTN) table for use in a telephone network, the method comprising:

automatically generating a client table comprising a plurality of records, each record comprising a spatial key and a telephone number associated with a client location;

providing a master table comprising a plurality of records, each record comprising a telephone number and a spatial key; and

matching the master table with the client table to produce records for the TNTTN table.

2. The method defined in claim 1, wherein matching for each unique spatial key in the master table comprises:

generating a single record in the TNTTN table for each master table record having the spatial key if the master table spatial key matches a single spatial key in the client table; and

generating a plurality of records in the TNTTN table for each master table record having the spatial key if the master table spatial key matches a plurality of spatial keys in the client table, wherein each of the plurality of records in the TNTTN table comprises a telephone number indicative of a client location.

3. The method defined in claim 1, additionally comprising sorting the client table by the spatial key.

4. The method defined in claim 1, additionally comprising sorting the master table by the spatial key.

5. The method defined in claim 1, wherein the spatial key comprises a postal code.

6. The method defined in claim 1, wherein the spatial key comprises one of the following:

census blocks, ordnance coordinates and quad trees.

7. A method of automatically generating a telephone number to telephone number (TNTTN) table for use in a telephone network, the method comprising:

automatically generating a client table comprising a plurality of records, each record comprising a spatial key and client information indicative of a service location;

providing a master table comprising a plurality of records, each record comprising a telephone number and a spatial key; and

matching the master table with the client table to produce records for the TNTTN table.

8. The method defined in claim 7, wherein matching for each unique spatial key in the master table comprises:

generating a single record in the TNTTN table for each master table record having the spatial key if the master table spatial key matches a single spatial key in the client table; and

generating a plurality of records in the TNTTN table for each master table record having the spatial key if the master table spatial key matches a plurality of spatial keys in the client table, wherein each of the plurality of records in the TNTTN table comprises a telephone number indicative of a client location.

9. The method defined in claim 7, additionally comprising sorting the client table by the spatial key.

10. The method defined in claim 7, additionally comprising sorting the master table by the spatial key.

11. The method defined in claim 7, wherein the client information comprises a service location identification (ID).

12. The method defined in claim 7, wherein the client information comprises a service location telephone number.

13. The method defined in claim 7, wherein the client table is generated by an automated process.

14. The method defined in claim 7, wherein the telephone number to telephone number table is generated by an automated process.

15. The method defined in claim 7, wherein the spatial key comprises a postal code.

16. The method defined in claim 7, wherein the spatial key comprises one of the following:

census blocks, ordnance coordinates and quad trees.

17. A method of automatically generating a caller telephone number to telephone number (CTNTTN) table for use in a telephone network, the method comprising:

automatically generating a client table comprising a plurality of records, each record comprising at least one spatial key and a telephone number associated with a client location;

providing a master table comprising a plurality of records, each record comprising a caller telephone number and a spatial key; and

matching the master table with the client table to produce records for the CTNTTN table, wherein matching for each unique spatial key in the master table comprises generating a caller telephone number to client telephone number record in the CTNTTN table each time a master table record spatial key matches the spatial key in the client table.

18. The method defined in claim 17, additionally comprising sorting the client table by the spatial key.

19. The method defined in claim 17, additionally comprising sorting the master table by the spatial key.

20. An automated call processing system for use in a telephone network, the system comprising:

an inbound receiving module capable of receiving a dialed number identification service (DNIS) number and a caller optionally entered telephone number having a geographic location associated therewith;

a call processor responsive to the caller optionally entered telephone number for providing a client service location identification (ID), wherein a client service location ID is provided if the location associated with the caller optionally entered telephone number spatially lies within a service area having a client defined geographic configuration of substantially any desired shape and size, and wherein the processor utilizes a caller telephone number to service location ID table; and

an outbound calling module for transmitting the provided client service location ID to the telephone network.

21. The system defined in claim 20, wherein the call processor utilizes a plurality of telephone number to service location ID tables, and wherein the caller optionally entered telephone number is utilized to select one of the telephone number to service location ID tables.

22. The system defined in claim 20, wherein the client service location ID is an identification other than a telephone number.

23. The system defined in claim 20, wherein the client service location ID is a telephone number.
