Abstract

A system and method to access an information or electronic service uses a single access telephone number. The telephone number is used to access a particular service provider no matter where the subscriber is located, and may be, for example, 950-DATA, 1-800-ATT-DATA, or 1-500-EASY-DATA. The system and method are particularly well suited to internet access through internet service providers (ISPs).

Claims

1. A system for routing a call requesting access to a service provider based on the location of the caller, comprising:

at least one switching system having network interfaces within a telecommunications network for receiving a call having a prespecified dialed number and service provider code and for launching a query, in response to the call, that includes the service provider code and a number identifying the network interface through which the call was received; and

a database within the telecommunications network including at least one routing number associated with each of a plurality of service providers, wherein the database determines a routing number, in response to the query, for least cost access to a service provider corresponding to the service provider code, and returns the routing number to the switching system.

2. The system according to claim 1, wherein the switching system routes the call to the service provider based on the routing number.

3. The system according to claim 1, wherein a computer is coupled to one the network interfaces, the switching system prompts a user at the computer to select a service provider from a list, and the computer returns a selection to the switching system as the service provider code.

4. The system according to claim 3, wherein the switching system receives the list from the database.

5. The system according to claim 1, wherein a computer is coupled to the switching system and is configured to include the service provider code and the prespecified dialed number.

6. A method for routing a call requesting access to a service provider based on the location of the caller, comprising the steps of:

receiving a query from a caller through a telecommunications network, the query including a service provider code and a number associated with a network interface through which the call originated;

accessing a database including at least one service provider, each service provider having at least one corresponding routing number;

determining a routing number to access a service provider corresponding to the service provider code in a least cost manner, based on the network interface originating the call; and

returning the routing number to the telephone network in response to the query.

7. The method according to claim 6, wherein the determining step selects a local access telephone number as the routing number.

8. The method according to claim 6, wherein the determining step includes calculating the lowest cost routing number for accessing a service provider, based on a service fee charged by the service provider and a network fee charged for using the telecommunications network.

9. The method according to claim 6, wherein the telecommunications network connects the call based on the routing number.

10. The method according to claim 6, further comprising the steps of:

determining in response to the query an alternate routing number to access a service provider corresponding to the service provider code; and

returning the alternate routing number to the telecommunications network.

11. The method according to claim 10, wherein the telecommunications network connects the call to the alternate routing number if the routing number is not accessible.

12. The method according to claim 6, wherein the method is performed by a server coupled to the telecommunications network.

13. The method according to claim 12, wherein the server is a network control point.

14. The method according to claim 12, wherein the server is a service control point.

15. A computer program product, comprising:

a computer useable medium having computer program logic stored therein, wherein the computer program logic comprises;

receiving means for enabling a computer to receive a query from a telecommunications network including a service provider code and a location of a network interface of a call;

accessing means for enabling the computer to access a service provider database including at least one routing number corresponding to each service provider in the database;

determining means for enabling the computer to determine a routing number for least cost access to a service provider corresponding to the service provider code; and

returning means for enabling the computer to return the routing number to the telecommunications network in response to the query.

16. The computer program product according to claim 15, wherein the determining means determines a local access telephone number as the routing number.

17. The computer program product according to claim 15, wherein the determining means includes means for determining the routing number for least cost access to the service provider, based on a service fee charged by the service provider and a network fee charged for use the telecommunications network.
