Abstract

Information stored within an SS7 signaling network is inserted within fields of an ISUP signaling message that are not dedicated to another use and the signaling message is sent to a service control point (SCP) within the SS7 network. At the SCP, information is extracted from the ISUP signaling message and existing databases are modified to reflect the addition of the extracted information.

Claims

1. A method of modifying information stored within a signaling network, comprising:

inserting subscriber update information within fields of a signaling message that are available for storing information; and

sending the signaling message to the signaling network, the signaling message being configured so that the signaling network sends information to a signaling network database;

wherein the information sent to the signaling network database is not directly used in a call sequence.

2. The method of claim 1 wherein the signaling message is an Integrated Services User Part (ISUP) message.

3. The method of claim 2 wherein the signaling network database is a service control point of an SS7 network (SCP).

4. The method of claim 1 wherein:

sending the signaling message to the signaling network includes sending the signaling message to an intermediary switch within the signaling network, and wherein the intermediary switch is triggered by the signaling message to send information to a signaling network database.

5. The method of claim 4 wherein the intermediary switch is a local exchange carrier class 5 switch.

6. The method of claim 1 wherein information is inserted in at least one of optional and undefined parameters of an ISUP message.

7. The method of claim 6 wherein information is inserted in the optional parameters of an ISUP message.

8. The method of claim 6 wherein information is inserted in the undefined parameters of an ISUP message.

9. The method of claim 6 wherein the information is stored in an ISUP initial address message.

10. The method of claim 1 wherein the signaling network database is a service control point.

11. The method of claim 1 wherein the signaling message can be sent when updates to the signaling network database are not scheduled.

12. A method of modifying a communication service subscriber database within a service control point comprising:

extracting information from a signaling message;

obtaining specific subscriber information by interpreting data stored within particular signaling message parameters of the signaling message; and

updating the subscriber database based on the obtained information resulting in updated information;

wherein the updated information is not directly used in a call sequence.

13. The method of claim 12 wherein the signaling message is an Integrated Services User Part (ISUP) message.

14. The method of claim 13 wherein a program associated with the service control point extracts and interprets data stored in a particular signaling message when that message has been identified by the program.

15. The method of claim 12 wherein the particular signaling message is a Transactional Capabilities Application Part (TCAP) message.

16. The method of claim 12 wherein the subscriber information includes any information related to communication services provided to the subscribers.

17. The method of claim 12 further comprising:

sending appropriate signaling messages through the signaling network to subscribers based upon updates to the subscriber database substantially immediately after an update has been made to the subscriber database.

18. The method of claim 14 wherein the program associates signaling message parameters with particular subscriber information.

19. A method of relaying subscriber information for updating a signaling network database comprising:

receiving a signaling message, the signaling message being configured to update subscriber information in a signaling network database; and

sending the signaling message to a signaling switch connected to the signaling network database;

wherein the subscriber information sent to the signaling network database is not directly used in a call sequence.

20. The method of claim 19 wherein the signaling network database is a service control point in an SS7 signaling network.
