Abstract

The present invention provides a method of transitioning messages from a Signaling System 7 Network to a data network at a Signaling System 7 Gateway. The method is accomplished by receiving one or more Signaling System 7 messages at the Signaling System 7 Gateway, determining states of accessability of one or more extended capability codes listed within the Signaling System 7 gateway, where each extended capability code corresponds to one or more signaling end points within the data network, terminating the Signaling System 7 messages at the Signaling System 7 Gateway, determining the accessability of the signaling end points associated with the Signaling System 7 messages, and routing the Signaling System 7 messages based upon the accessability of the signaling end points.

Claims

1. A method of transitioning a message from a Signaling System 7 Network to a data network at a Signaling System 7 Gateway, the method comprising the steps of:

receiving one or more Signaling System 7 messages at the Signaling System 7 Gateway;

determining accessibility of one or more extended capability codes listed within the Signaling System 7 Gateway wherein each extended capability code corresponds to one or more signaling end points within the data network; and

terminating a Signaling System 7 (SS7) message received at the Signaling System 7 Gateway for transitioning to the data network if an extended capability code associated with the received SS7 message is accessible.

2. The method of claim 1 further comprising:

determining accessibility of a signaling end point associated with the received SS7 message after the received SS7 message is terminated; and

routing the received SS7 message to the associated signaling end point if the associated signaling end point is accessible.

3. The method of claim 2 further comprising:

converting the Signaling System 7 message to a data network message before the received SS7 message is routed.

4. The method of claim 3 wherein the data network message conforms with the Internet Protocol standard.

5. The method of claim 3 wherein the data network message conforms with the Transmission Control Protocol standard.

6. The method of claim 3 wherein the data network message conforms with the User Datagram Protocol standard.

7. The method of claim 3 wherein the step of routing further includes transmitting the data network message across the data network.

8. The method of claim 2 further comprising:

discarding the received Signal System 7 message, if the signaling end point is inaccessible.

9. The method of claim 8 further comprising:

sending a blocking message to a source from which the received Signaling System 7 message was originally sent after the received SS7 message is discarded.

10. The method of claim 1 wherein the Signaling System 7 Gateway includes at least one mated pair of signaling transfer points.

11. The method of claim 1 further comprising:

discarding the received SS7 message if the associated extended capability code is not accessible.

12. The method of claim 11 further comprising:

sending a notification to a source from which the received SS7 message was originally sent after the received SS7 message is discarded, said notification informing the source that the extended capability code associated with the received SS7 message is not accessible.

13. A Gateway for transitioning a message from a Signaling System 7 Network to a data network, said Gateway being coupled to me Signaling System 7 Network and the data network and being adapted to:

receive one or more Signaling System 7 (SS7) messages from the Signaling System 7 Network,

determine accessibility of one or more extended capability codes listed within the Gateway, wherein each extended capability code corresponds to one or more signaling end points within the data network, and

terminate a Signaling System 7 message received at the Gateway for transitioning to the data network if an extended capability code associated with the received SS7 message is accessible.

14. The gateway of claim 13 further being adapted to:

determine accessibility of a signaling end point associated with the received SS7 message after the received SS7 message is terminated; and

route the received SS7 message to the associated signaling end point if the associated signaling and point is accessible.

15. The Gateway of claim 14 further being adapted to convert the received Signaling System 7 message a data network message before the received SS7 message is routed.

16. The Gateway of claim 15 wherein the data network message conforms with the Internet Protocol standard.

17. The Gateway of claim 15 wherein the data network message conforms with the Transmission Control Protocol standard.

18. The Gateway of claim 15 wherein the data network message conforms with the User Datagram Protocol standard.

19. The Gateway of claim 14 further being adapted to discard the received Signaling System 7 message if the signaling end point is inaccessible.

20. The Gateway of claim 19 further being adapted to send a blocking message to a source from which the received Signaling System 7 message was originally sent after the received SS7 message is discarded.

21. The system Gateway of claim 13 comprising at least one mated pair of signaling transfer points.

22. The gateway of claim 13 further being adapted to:

discard the received SS7 message if the associated extended capability code is not accessible.

23. The gateway of claim 22 further being adapted to:

send a notification to a source from which the received SS7 message was originally sent after the received SS7 message is discarded, said notification informing the source that the extended capability code associated with the received SS7 message is not accessible.

24. A computer program embodied on a computer readable medium for transitioning a message from a Signaling System 7 Network to a data network at a Signaling System 7 (SS7) Gateway comprising:

a code segment for receiving one or more Signaling System 7 messages at the a Signaling System 7 Gateway;

a code segment for determining accessibility of one or more extended capability codes listed within the Signaling System 7 Gateway, wherein each extended capability code corresponds to one or more signaling end points within the data network; and

a code segment for terminating a Signaling System 7 message received at the Signaling System 7 Gateway for transitioning to the data network if an extended capability code associated with the received SS7 message is accessible.

25. The computer program of claim 24 further comprising:

a code segment for determining accessibility of a signaling end point associated with the received SS7 message after the received SS7 message is terminated; and

a code segment for routing the received SS7 message to the associated signaling end point if the associated signaling end point is accessible.

26. The computer program of claim 25 a further comprising:

a code segment for converting the received Signaling System 7 message to a data network message before the SS7 message is routed.

27. The computer program of claim 25 the code segment for routing includes codes for transmitting the data network message across the data network.

28. The computer program of claim 25 further comprising:

a code segment for discarding the received Signaling System 7 message if the signaling end point is inaccessible.

29. The computer program of claim 28 further comprising:

a code segment for sending a blocking message to a source from which the received SS7 message was originally sent after the received SS7 message is discarded.

30. The computer program of claim 24 wherein the Gateway includes at least one mated pair of signaling transfer points.

31. The computer program of claim 24 further comprising:

a code segment for discarding the received SS7 message if the associated extended capability code is not accessible.

32. The computer program of claim 31 further comprising:

a code segment for sending a notification to a source from which the received SS7 message was originally sent after the received SS7 message is discarded, said notification informing the source that the extended capability code associated with the received SS7 message is not accessible.
