Abstract

Methods, systems, and computer program products for providing address translation using subsequent address information are disclosed. According to one method, a first call setup signaling message containing a first portion of a called party identifier is received. A second call setup signaling message containing a second portion of the called party identifier is received. The first and second portions of the called party identifier are used to perform an address translation.

Claims

1. A method for providing call setup signaling message address translation in a communications network, the method comprising:

(a) receiving a first call setup signaling message containing a first portion of a called party identifier;

(b) receiving a second call setup signaling message containing a second portion of the called party identifier; and

(c) using the first and second portions of the called party identifier in combination to perform an address translation.

2. The method of claim 1 wherein receiving a first call setup signaling message includes receiving an ISUP IAM message.

3. The method of claim 2 wherein the first portion of a called party identifier is contained in an ISUP called party number (CdPN) parameter.

4. The method of claim 1 wherein receiving a second call setup signaling message includes receiving an ISUP SAM message.

5. The method of claim 4 wherein the second portion of the called party identifier is contained in an ISUP subsequent number parameter.

6. The method of claim 1 wherein a called party identifier comprises a telephone number.

7. The method of claim 1 wherein using the first and second portions of the called party identifier in combination to perform an address translation includes using the first and second portions of the called party identifier in combination to perform a number portability translation.

8. The method of claim 7 wherein performing a number portability translation includes using the first and second portions of the called party identifier in combination to locate a location routing number (LRN) associated with the called party identifier.

9. The method of claim 8 including modifying the first call setup signaling message to include the LRN.

10. The method of claim 1 including modifying the first call setup signaling message to include the first and second portions of the called party identifier.

11. The method of claim 1 wherein using the first and second portions of the called party identifier in combination to perform an address translation includes using the first and second portions of the called party identifier in combination to perform an ENUM translation.

12. The method of claim 11 wherein performing an ENUM translation includes using the first and second portions of the called party identifier in combination to locate a uniform resource identifier (URI).

13. The method of claim 12 including generating a session initiation protocol (SIP) message which includes the URI.

14. The method of claim 1 wherein steps (a) through (c) are performed at a network routing node.

15. The method of claim 1 wherein steps (a) through (c) are performed at a call processing node.

16. A system for providing call setup signaling message address translation in a communications network, the system comprising:

a network node including;

(a) a communication interface for receiving first and second call setup messages associated with a call in a communications network, wherein the first call setup signaling message includes a first portion of a called party identifier and the second call setup signaling message includes a second portion of the called party identifier;

(b) a consolidation function for;

(i) receiving the first and second call setup messages from the communication interface; and

(ii) combining the first and second portions of the called party identifier; and

(c) an address translation function for receiving the combined called party identifier and using the combined called party identifier to perform an address translation.

17. The system of claim 16 wherein the first call setup signaling message includes an ISUP IAM message, and the second call setup signaling message includes an ISUP SAM message.

18. The system of claim 16 wherein the communication interface is adapted to send and receive signaling system 7 (SS7) signaling messages.

19. The system of claim 16 wherein the communication interface is adapted to send and receive Internet Engineering Task Force (IETF) SIGTRAN signaling messages.

20. The system of claim 16 wherein the consolidation function is adapted to modify the first call setup signaling message to include the first and second portions of the called party identifier.

21. The system of claim 16 wherein an address translation function includes a number portability translation application for performing number portability translation.

22. The system of claim 21 wherein the number portability translation application is adapted to use the combined called party identifier to locate a location routing number (LRN) associated with the called party identifier.

23. The system of claim 22 wherein the number portability translation application is adapted to modify the first call setup signaling message to include the LRN.

24. The system of claim 16 wherein the address translation function includes an ENUM application for performing an ENUM translation.

25. The system of claim 24 wherein the ENUM application is adapted to use the combined called party identifier to locate a uniform resource identifier (URI).

26. The system of claim 25 including a call processor function for generating a session initiation protocol (SIP) message, which includes the URI.

27. The system of claim 16 wherein the network node comprises a network routing node.

28. The system of claim 16 wherein the network node comprises a call processing node.

29. A computer program product comprising computer-executable instructions embodied in a computer-readable medium for performing steps comprising:

(a) receiving a first call setup signaling message containing a first portion of a called party identifier;

(b) receiving a second call setup signaling message containing a second portion of the called party identifier; and

(c) using the first and second portions of the called party identifier in combination to perform an address translation.

30. The computer program product of claim 29 wherein receiving a first call setup signaling message includes receiving an ISUP IAM message.

31. The computer program product of claim 30 wherein the first portion of a called party identifier is contained in an ISUP called party number (CdPN) parameter.

32. The computer program product of claim 29 wherein receiving a second call setup signaling message includes receiving an ISUP SAM message.

33. The computer program product of claim 32 wherein the second portion of the called party identifier is contained in an ISUP subsequent number parameter.

34. The computer program product of claim 29 wherein a called party identifier comprises a telephone number.

35. The computer program product of claim 29 wherein using the first and second portions of the called party identifier in combination to perform an address translation includes using the first and second portions of the called party identifier in combination to perform a number portability translation.

36. The computer program product of claim 35 wherein performing a number portability translation includes using the first and second portions of the called party identifier in combination to locate a location routing number (LRN) associated with the called party identifier.

37. The computer program product of claim 36 including modifying the first call setup signaling message to include the LRN.

38. The computer program product of claim 29 including modifying the first call setup signaling message to include the first and second portions of the called party identifier.
