Abstract

Method and apparatus for identifying on-line access calls in a network switch. The switch determines which calls are to an on-line service provider, usually an Internet service provider or ISP. The switch then determines if the service provider has enough ports available to handle the call, and if the connection to a dedicated data network has enough capacity. The call can then be handled as an on-line access call and routed accordingly. The initial determination as to whether the call is an on-line access call can be made by analyzing information received when the call is initiated such as the called party number digits or by a query initiated by an advanced intelligent network (AIN) trigger.

Claims

1. In a switch, a method of identifying on-line access calls, the method comprising the steps of:

collecting and analyzing information received during a call;

determining if the called party number is a service provider number;

if the called party number is a service provider number, determining if a port number for the service provider will be exceeded;

if the port number will not be exceeded, determining if a local area network (LAN) maximum capacity will be exceeded;

updating numerical tables to account for the call; and

setting up the call using a dedicated data network which is connected to the switch and the service provider.

2. The method of claim 1 wherein the information collected and analyzed is the called party number (CDN).

3. The method of claim 1 wherein the information collected and analyzed is an access code dialed by a user.

4. The method of claim 1 wherein the information collected and analyzed is information contained in a set-up message.

5. The method of claim 1 wherein the information collected and analyzed is bearer capability information.

6. In a switch, a method of identifying on-line access calls, the method comprising the steps of:

encountering an advanced intelligent network (AIN) trigger when a call is received;

sending a query to a database to determine if the call is to a service provider;

if the call is to a service provider, determining if a port number for the service provider will be exceeded;

if the port number will not be exceeded, determining if a local area network (LAN) maximum capacity will be exceeded;

updating numerical tables to account for the call; and

setting up the call using a dedicated data network which is connected to the switch and the service provider.

7. The method of claim 6 wherein the database is a service control point (SCP).

8. The method of claim 6 wherein the database is an adjunct.

9. A computer program product for use with a switch, the computer program product having a medium with computer program code embodied therein, the computer program code comprising:

computer program code for collecting and analyzing information received during a call;

computer program code for determining if the called party number is a service provider number;

computer program code for if the called party number is a service provider number, determining if a port number for the service provider will be exceeded;

computer program code for if the port number will not be exceeded, determining if a local area network (LAN) maximum capacity will be exceeded;

computer program code for updating numerical tables to account for the call; and

computer program code for setting up the call using a dedicated data network which is connected to the switch and the service provider.

10. The computer program product of claim 9 wherein the information collected and analyzed is the called party number (CDN).

11. The computer program product of claim 9 wherein the information collected and analyzed is an access code dialed by a user.

12. The computer program product of claim 9 wherein the information collected and analyzed is information contained in a set-up message.

13. The computer program product of claim 9 wherein the information collected and analyzed is bearer capability information.

14. A computer program product for use with a switch, the computer program product having a medium with computer program code embodied therein, the computer program code comprising:

computer program code for encountering an advanced intelligent network (AIN) trigger when a call is received;

computer program code for sending a query to a database to determine if the call is to a service provider;

computer program code for if the call is to a service provider, determining if a port number for the service provider will be exceeded;

computer program code for if the port number will not be exceeded, determining if a local area network (LAN) maximum capacity will be exceeded;

computer program code for updating numerical tables to account for the call; and

computer program code for setting up the call using a dedicated data network which is connected to the switch and the service provider.

15. The computer program product of claim 14 wherein the database is a service control point (SCP).

16. The computer program product of claim 14 wherein the database is an adjunct.

17. A switch for connection in a switched network, the switch comprising:

adapters for connection to customer premises equipment (CPE) and a local area network (LAN) which is in turn connected to a dedicated data network;

a switch matrix disposed between the adapters; and

a processing core connected to the switch matrix, the processing core having computer program code for identifying an on-line access call directed to a service provider, determining if a port number for the service provider will be exceeded, determining if a maximum capacity of the LAN will be exceeded, and setting up the on-line access call using the dedicated data network.

18. The switch of claim 17 wherein identifying the on-line access call is accomplished through analysis of information received when the call is initiated.

19. The switch of claim 17 wherein identifying the on-line access call is accomplished through a database query initiated when an advanced intelligent network (AIN) trigger is encountered.

20. The switch of claim 19 wherein the database query is made to a service control point (SCP).

21. The switch of claim 19 wherein the database query is made to an adjunct.

22. A network in which on-line access calls can be identified for redirection from a public network switching fabric to a dedicated data network switching fabric, the network comprising:

customer premises equipment (CPE);

a point of presence (POP) for a service provider connected to a dedicated data network;

a local area network (LAN) connected to the dedicated data network; and

a switch disposed between the CPE and the LAN, the switch having a processing core having computer program code for identifying an on-line access call directed to a service provider, determining if a port number for the service provider will be exceeded, determining if a maximum capacity of the LAN will be exceeded, and setting up the on-line access call using the dedicated data network.

23. The network of claim 22 wherein identifying the on-line access call is accomplished through analysis of digits of a called party number (CDN).

24. The network of claim 22 wherein identifying the on-line access call is accomplished through a database query initiated when an advanced intelligent network (AIN) trigger is encountered.

25. The network of claim 24 wherein the database query is made to a service control point (SCP).

26. The network of claim 24 wherein the database query is made to an adjunct.
