Telecommunications apparatus, system, and method with an enhanced signal transfer point
View Patent ↗The present invention is an apparatus, system, and method for converting point codes in a signal transfer point in a telecommunications signaling system. The STP converts point codes which designate the origination and destination signaling points for the message. The conversion is based on information defined by the messages, such as origination or destination information. The present invention creates a virtual signaling system which can be reconfigured at the STP by converting point codes, and thus, altering the identities of the signaling points. The present invention is also operable to convert circuit identification codes and transfer integrated services user part messages to a user part.
1. A signaling network, comprising:
a signaling transfer point configured to receive a call-related signaling message having a first point code, convert the first point code to a second point code in the signaling message, transfer the signaling message having the second point code, generate a management message having the second point code, convert the second point code to the first point code in the management message, and transfer the management message; and
a signaling system configured to receive the management message from the signaling transfer point.
2. The signaling network of claim 1 , wherein the signaling message comprises a Signaling System #7 message.
3. The signaling network of claim 1 , wherein the signaling transfer point is configured to convert the second point code to the first point code in the management message based on a destination point code of the management message.
4. The signaling network of claim 1 , wherein the signaling transfer point is configured to convert the second point code to the first point code in the management message based on an origination point code of the management message.
5. The signaling network of claim 1 , wherein the signaling system comprises a switch.
6. The signaling network of claim 1 , wherein the signaling transfer point is configured to:
identify a problem with a link associated with the second point code, and
convert the second point code to the first point code in the management message responsive to identifying the problem.
7. The signaling network of claim 6 , wherein the problem with the link comprises congestion on the link.
8. The signaling network of claim 6 , wherein the signaling system is configured to:
process the management message to avoid transmitting signaling messages to the first point code.
9. The signaling network of claim 1 , wherein the management message comprises a transfer restricted message.
10. A method of operating a signaling network, the method comprising the steps of:
receiving a call-related signaling message having a first point code in a signaling transfer point; and
in the signaling transfer point,
converting the first point code to a second point code in the signaling message;
transferring the signaling message having the second point code,
generating a management message having the second point code,
converting the second point code to the first point code in the management message, and
transferring the management message.
11. The method of claim 10 , wherein the signaling message comprises a Signaling System #7 message.
12. The method of claim 10 , wherein the step of convening the second point code to the first point code in the management message comprises:
convening the second point code to the first point code in the management message based on a destination point code of the management message.
13. The method of claim 10 , wherein the step of convening the second point code to the first point code in the management message comprises:
convening the second point code to the first point code in the management message based on an origination point code of the management message.
14. The method of claim 10 , wherein the signaling system comprises a switch.
15. The method of claim 10 , funher comprising the steps of:
in the signaling transfer point,
identifying a problem with a link associated with the second point code, and
convening the second point code to the first point code in the management message responsive to identifying the problem.
16. The method of claim 15 , wherein the problem with the link comprises congestion on the link.
17. The method of claim 15 , further comprising the steps of:
receiving the management message in a signaling system, and
processing the management message in the signaling system to avoid transmitting signaling messages to the first point code.
18. The method of claim 10 , wherein the management message comprises a transfer restricted message.
