Abstract

The subject matter disclosed herein includes methods, systems, and computer program products for selecting among different global title translation modes based on a message originator and performing global title translation based on the selected mode. According to one method, a global title translation mode is selected based on a message originator. A global title translation lookup is performed in accordance with the selected mode. If the global title translation according to the selected mode fails, a lookup may be performed according to at least one additional mode in a global title translation mode hierarchy.

Claims

1. A method for global title translation in a telecommunications network, the method comprising:

(a) receiving a signaling message that requires global title translation (GTT);

(b) selecting a GTT mode from a plurality of different GTT modes based on an originator of the signaling message; and

(c) performing a GTT lookup according to the selected GTT mode.

2. The method of claim 1 wherein receiving a signaling message includes receiving an SS7 signaling message.

3. The method of claim 1 wherein receiving a signaling message includes receiving a signaling connection control part (SCCP) message.

4. The method of claim 1 wherein selecting a GTT mode from a plurality of different GTT modes based on an originator includes selecting a GTT mode based on an incoming linkset of the received signaling message.

5. The method of claim 1 wherein performing a GTT lookup according to the selected GTT mode including searching a GTT database using parameters specific to the GTT mode.

6. The method of claim 1 wherein the plurality of different GTT modes are arranged in a user defined hierarchy and wherein the method further comprises, in response to failing to locate a matching entry using the selected GTT mode, performing a GTT lookup according to a next GTT mode in the GTT hierarchy.

7. The method of claim 1 wherein the plurality of GTT modes includes an advanced called party GTT mode in which the GTT lookup is performed based on at least one of called party parameters, calling party parameters, and message transfer part (MTP) parameters in the signaling message.

8. The method of claim 7 wherein the plurality of GTT modes includes a calling party GTT mode where the GTT lookup is performed based on calling party parameters in the signaling message.

9. The method of claim 8 wherein the plurality of GTT modes includes a called party GTT mode where the GTT lookup is performed based on called party parameters in the signaling message.

15. The method of claim 1 wherein performing a GTT lookup according to the selected GTT mode includes generating an error message based on results of the GTT lookup.

10. A method for global title translation in a telecommunications network, the method comprising:

(a) receiving a signaling message that requires global title translation (GTT);

(b) selecting a GTT mode from a plurality of different GTT modes, at least one of the GTT modes including a GTT lookup parameter other than or in addition to a signaling connection control part (SCCP) called party address; and

(c) performing a GTT lookup according to the selected GTT mode, wherein performing GTT according to the selected GTT mode includes performing the GTT lookup using parameters from the signaling message corresponding to the selected GTT mode.

11. The method of claim 10 wherein selecting a GTT mode from the plurality of GTT modes includes selecting a GTT mode based on at least one of a message transfer part (MTP), a signaling connection control part (SCCP), and a transaction capabilities application part (TCAP) parameter in a signaling message.

12. The method of claim 10 wherein selecting a GTT mode includes selecting the GTT mode using at least one criterion separate from parameters in the signaling message.

13. The method of claim 10 wherein performing a GTT lookup according to the selected GTT mode includes discarding the signaling message based on results of the GTT lookup.

14. The method of claim 10 wherein performing a GTT lookup according to the selected GTT mode includes copying the signaling message based on results of the GTT lookup.

16. A system for global title translation (GTT) in a telecommunications network, the system comprising:

(a) a communications link module for sending signaling messages to and receiving signaling messages from a network;

(b) a GTT database; and

(c) a global title translation engine operatively associated with the communications link module for receiving signaling messages from the communications link module requiring global title translation, for selecting a GTT mode from a plurality of different GTT modes based on an originator of the signaling message, and for searching the GTT database according to the selected GTT mode.

17. The system of claim 16 wherein the communications link module comprises an SS7 link interface module.

18. The system of claim 16 wherein the communications link module comprises an IP telephony signaling link interface module.

19. The system of claim 16 wherein the GTT engine is adapted to select the GTT mode based on an incoming linkset from which each message is received.

20. The system of claim 16 wherein each GTT mode includes different parameters or combinations of parameters for searching the GTT database.

21. The system of claim 16 wherein the different GTT modes are ordered in a user defined hierarchy, wherein performing the GTT lookup according to the selected mode includes performing the GTT lookup according to a most preferred mode in the hierarchy, and in response to failing to locate a lookup according to the most preferred mode, performing a lookup according to at least one lesser-preferred mode in the hierarchy.

22. The system of claim 16 wherein the plurality of different GTT modes include an advanced called party GTT mode in which the GTT lookup is performed based on at least one of calling party parameters, called party parameters, and message transfer part (MTP) parameters in the signaling message.

23. The system of claim 22 wherein the plurality of GTT modes includes a calling party GTT mode in which the GTT lookup is performed based on calling party parameters in the signaling message.

24. The system of claim 23 wherein the plurality of GTT modes includes a called party GTT mode in which the GTT lookup is performed based on a called party parameter in the signaling message.

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

(a) receiving a signaling message that requires global title translation (GTT);

(b) selecting a GTT mode from a plurality of different GTT modes based on an originator of the signaling message; and

(c) performing a GTT lookup according to the selected GTT mode.

26. The computer program product of claim 25 wherein receiving a signaling message includes receiving an SS7 signaling message.

27. The computer program product of claim 25 wherein receiving a signaling message includes receiving a signaling connection control part (SCCP) message.

28. The computer program product of claim 25 wherein selecting a GTT mode from a plurality of different GTT modes based on an originator includes selecting a GTT mode based on an incoming linkset of the received signaling message.
