Abstract

The invention is directed to selecting access tandem switches to be connected to an information assistance provider. It has been recognized that each access tandem switch serves a telephone user population which varies with the NPA/NXXs associated therewith. In accordance with the invention, the information assistance provider selects for connection, as few access tandem switches serving as many telephone users as possible. To that end, for each access tandem switch, data about how many telephone users are assigned to each NPA/NXX associated with the access tandem switch is analyzed to assess the number of telephone users served by the access tandem switch.

Claims

1. A method for use by an information assistance provider connecting information assistance callers to desired telephone numbers through selected switches provided by a carrier, comprising:

determining, based on telephone listings, numbers of telephone users served by a plurality of switches provided by the carrier, respectively; and

selecting one or more of the plurality of switches for connecting information assistance callers to desired telephone numbers based on the respective numbers of telephone users served thereby.

2. The method of claim 1 wherein the plurality of switches includes end office switches.

3. The method of claim 1 wherein the plurality of switches includes access tandem switches.

4. The method of claim 1 wherein the plurality of switches includes NPA/NXX switches.

5. The method of claim 1 wherein the respective numbers of telephone users served by the one or more of the plurality of switches is determined as a function of a number of the telephone listings associated with the one or more of the plurality of switches.

6. The method of claim 5 wherein the function includes a sum or a ratio.

7. The method of claim 1 wherein the one or more of the plurality of switches is selected when the respective numbers of telephone users served by the one or more of the plurality of switches is greater than a predetermined number.

8. A method for use by an information assistance provider connecting information assistance callers to desired telephone numbers through selected switches provided by a carrier, comprising:

selecting one or more of the plurality of switches for connecting information assistance callers to desired telephone numbers based on numbers of telephone calls connected to the one or more of the plurality of switches.

9. The method of claim 8 wherein the number of telephone calls connected to the one or more of the plurality of switches includes a function of a number of users served thereby.

10. A system for use by an information assistance provider connecting information assistance callers to desired telephone numbers through selected switches provided by a carrier, comprising:

a processor for determining, based on telephone listings, numbers of telephone users served by a plurality of switches provided by the carrier, respectively, one or more of the plurality of switches for connecting information assistance callers to desired telephone numbers being selected based on the respective numbers of telephone users served thereby.

11. The system of claim 10 wherein the plurality of switches includes end office switches.

12. The system of claim 10 wherein the plurality of switches includes access tandem switches.

13. The system of claim 10 wherein the plurality of switches includes NPA/NXX switches.

14. The system of claim 10 wherein the respective numbers of telephone users served by the one or more of the plurality of switches is determined as a function of a number of the telephone listings associated with the one or more of the plurality of switches.

15. The system of claim 14 wherein the function includes a sum or a ratio.

16. The system of claim 10 wherein the one or more of the plurality of switches is selected when the respective numbers of telephone users served by the one or more of the plurality of switches is greater than a predetermined number.

17. A system for use by an information assistance provider connecting information assistance callers to desired telephone numbers through selected switches provided by a carrier, comprising:

a processor for selecting one or more of the plurality of switches for connecting information assistance callers to desired telephone numbers based on numbers of telephone calls connected to the one or more of the plurality of switches.

18. The system of claim 17 wherein the number of telephone calls connected to the one or more of the plurality of switches includes a function of a number of users served thereby.
