Apparatus and method for translating global title in No. 7 signaling network

1. An apparatus for translating a global title (GT) in a common channel signaling network, comprising:

a general global title translation (GTT) module configured to perform a general GTT function of a first signaling point;

a pre-fetch GTT module configured to distribute the general GTT function to a second signaling point before the general GTT function is performed; and

a post-fetch GTT module configured to provide the general GTT function to the second signaling point when the general GTT function fails.

2. The apparatus of claim 1 , wherein the common channel signaling network is a No. 7 signaling network.

3. The apparatus of claim 1 , wherein the pre-fetch GTT module is enabled when a GTT type making a signaling transfer point perform the general GTT function is applied to a signaling network.

4. The apparatus of claim 1 , wherein the pre-fetch GTT module is disabled when a GTT type making an originating signaling point perform the general GTT function is applied to a signaling network.

5. The apparatus of claim 1 , wherein the pre-fetch GTT module is enabled when the first signaling point cannot perform the general GTT function.

6. The apparatus of claim 1 , wherein the pre-fetch GTT module comprises a pre-fetch GTT database, and wherein the post-fetch GTT module comprises a post-fetch GTT database.

7. The apparatus of claim 6 , wherein the pre-fetch GTT database and the post-fetch GTT database respectively have a field to indicate an enabled/disabled state of a pertinent function and a signaling point code for transmitting a pertinent signaling message.

8. A method for translating a global title (GT) in a common channel signaling network, comprising:

determining whether a pre-fetch global title translation (GTT) module is enabled when a transmission request of a signaling message including a GT is received at a first signaling point;

performing a pre-fetch GTT when the pre-fetch GTT module is enabled;

performing a general GTT when the pre-fetch GTT module is not enabled;

determining whether a post-fetch GTT module is enabled when the general GTT has failed; and

performing a post-fetch GTT when the post-fetch GTT module is enabled.

9. The method of claim 8 , wherein the common channel signaling network is a No. 7 signaling network.

10. The method of claim 8 , further comprises discarding the signaling message when the post-fetch GTT module is not enabled.

11. The method of claim 8 , wherein determining whether the pre-fetch GTT module is enabled is performed by checking information recorded on a prescribed field of the pre-fetch GTT database.

12. The method of claim 8 , wherein the pre-fetch GTT retrieves a signaling point that performs a GTT of the signaling message in the pre-fetch GTT database.

13. The method of claim 8 , wherein determining whether the post-fetch GTT module is enabled is performed by checking information recorded on a prescribed field of a post-fetch GTT database.

14. The method of claim 8 , wherein the post-fetch GTT retrieves a signaling point that performs a GTT of the signaling message in the post-fetch GTT database.

15. A method for translating a GT (global title) in a No.7 signaling network, comprising:

controlling a pre-fetch global title translation (GTT) function and a post-fetch GTT function of each of a plurality of signaling points according to a GTT type applied to a signaling network; and

performing GTT according to the controlled pre-fetch GTT function and the post-fetch GTT function.

16. The method of claim 15 , wherein controlling the pre-fetch GTT function and the post-fetch GTT function of each signaling point comprises:

setting an enabled/disabled state of the pre-fetch GTT function and the post-fetch GTT function of each signaling point according to the GTT type;

managing GTT information required by each signaling point by dispersing the GTT information; and

setting another signaling point performing a general GTT as a substitute for each signaling point.

17. The method of claim 15 , wherein a GTT type of a prescribed signaling point can be controlled by controlling a pre-fetch GTT function and a post-fetch GTT function of a prescribed signaling point.

18. An apparatus for translating a global title (GT) in a common channel signaling network, comprising:

a general global title translation (GTT) module configured to perform a general GTT function of a first signaling point; and

at least one of a pre-fetch GTT module configured to distribute the general GTT function to a second signaling point before the general GTT function is performed and a post-fetch GTT module configured to provide the general GTT function to the second signaling point if the general GTT function fails.

19. The apparatus of claim 18 , wherein the pre-fetch GTT module comprises a pre-fetch GTT database, and wherein the post-fetch GTT module comprises a post-fetch GTT database.

20. The apparatus of claim 19 , wherein the pre-fetch GTT database and the post-fetch GTT database respectively have a field to indicate an enabled/disabled state of a pertinent function and a signaling point code for transmitting a pertinent signaling message.

21. A method for translating a global title (GT) in a common channel signaling network, comprising:

determining whether a pre-fetch global title translation (GTT) module is enabled when a transmission request of a signaling message including a GT is received at a first signaling point;

performing a pre-fetch GTT when the pre-fetch GTT module is enabled; and

performing a general GTT when the pre-fetch GTT module is not enabled.

22. The method of claim 21 , further comprising

determining whether a post-fetch GTT module is enabled when the general GTT is attempted and is determined to have failed; and

performing a post-fetch GTT when the post-fetch GTT module is enabled.
