Abstract

A method and apparatus to manage network correction procedures is disclosed. An example method includes receiving an alarm relating to a network anomaly, receiving information relating to the location of the network anomaly, and determining an identity of at least one network element related to the location. The example method also includes ranking a list of corrective procedures, and selecting at least one corrective procedure from the list of corrective procedures.

Claims

1. A method for invoking network correction procedures, comprising:

receiving an alarm relating to a network anomaly;

receiving information relating to the location of the network anomaly;

determining an identity of at least one network element related to the location;

ranking a list of corrective procedures; and

selecting at least one corrective procedure from the list of corrective procedures.

2. A method as defined in claim 1, wherein ranking the list of corrective procedures comprises:

receiving at least one keyword describing the network anomaly;

querying a resolution database with the at least one keyword and the information relating to the location of the network anomaly;

receiving the list of corrective procedures; and

arranging the list of corrective procedures based on the number of times each procedure was used.

3. A method as defined in claim 1, wherein receiving the alarm comprises receiving a message that at least one predetermined threshold has been triggered, the predetermined threshold indicative of network performance.

4. A method as defined in claim 1, wherein the information received relating to the location of the network anomaly comprises at least one of a zip-code, an address, a street intersection, a latitude, a longitude, a customer telephone number, or a customer account number.

5. A method as defined in claim 1, wherein determining the identity of the at least one network element comprises querying a topology database, the query providing the information relating to the location of the network anomaly.

6. A method as defined in claim 1, wherein receiving the alarm comprises receiving a trouble ticket in response to a customer complaint.

7. A method as defined in claim 1, wherein selecting the at least one corrective procedure comprises querying a rule database to determine a preference for one of the at least one corrective procedure.

8. A method as defined in claim 1, further comprising determining if two or more corrective procedures have the same rank.

9. A method as defined in claim 8, further comprising performing a query on a rule database to determine a preference for one of the two or more corrective procedures.

10. A method as defined in claim 1, wherein selecting the at least one corrective procedure comprises determining a customer impact of the at least one corrective procedure.

11. A method as defined in claim 10, further comprising selecting the at least one corrective procedure having the lowest customer impact.

12. A system for invoking network correction procedures, comprising:

a network manager to receive a notification message indicative of a network error associated with a network;

a decision rule engine to receive the notification message and rank a list of correction procedures related to repair of the network error, wherein the decision rule engine is to invoke a rule database to select at least one of the correction procedures; and

a testing system to execute the at least one correction procedure.

13. A system for invoking network correction procedures as defined in claim 12, wherein the network manager comprises an alarm collection system to monitor the network for one or more violations of one or more network performance thresholds, wherein each violation is indicative of the network error.

14. A system for invoking network correction procedures as defined in claim 12, further comprising a topology database to determine an identity of at least one network element (NE) associated with the network error.

15. A system for invoking network correction procedures as defined in claim 14, wherein the topology database returns the NE identity based on information indicative of the location of the network error.

16. A system for invoking network correction procedures as defined in claim 15, wherein the information indicative of the location of the network error comprises at least one of a zip-code, an address, a street intersection, a latitude, a longitude, a customer telephone number, or a customer account number.

17. A system for invoking network correction procedures as defined in claim 12, further comprising a resolution database to store a plurality of network correction procedures.

18. A system for invoking network correction procedures as defined in claim 17, wherein the resolution database comprises a count value indicative of successful implementations for each one of the plurality of network correction procedures.

19. A system for invoking network correction procedures as defined in claim 18, wherein each one of the plurality of network correction procedures is associated with at least one keyword.

20. A system for invoking network correction procedures as defined in claim 19, wherein the at least one keyword is indicative of at least one of a network element, a network element location, an error locality, or a failure description.

21. A system for invoking network correction procedures as defined in claim 12, wherein the rule database comprises a plurality of network correction procedures.

22. A system for invoking network correction procedures as defined in claim 21, wherein the plurality of network correction procedures comprises at least one of a network element command, a subroutine, or a script.

23. An article of manufacture storing machine readable instructions that, when executed, cause a machine to:

receive an alarm relating to a network anomaly;

receive information relating to the location of the network anomaly;

determine an identity of at least one network element related to the location;

rank a list of corrective procedures; and

select at least one corrective procedure from the list of corrective procedures.

24. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to:

receive at least one keyword describing the network anomaly;

query a resolution database with the at least one keyword and the information relating to the location of the network anomaly;

receive the list of corrective procedures; and

arrange the list of corrective procedures based on the number of times each procedure was used.

25. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to receive a message that at least one predetermined threshold has been triggered, wherein the predetermined threshold is indicative of network performance.

26. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to receive location information of at least one of a zip-code, an address, a street intersection, a latitude, a longitude, a customer telephone number, or a customer account number.

27. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to query a topology database to determine an identity of the at least one network element, wherein the query provides the information relating to the location of the network anomaly.

28. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to receive a trouble ticket in response to a customer complaint.

29. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to query a rule database to determine a preference for one of the at least one corrective procedures.

30. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to determine if two or more corrective procedures have the same rank.

31. An article of manufacture as defined in claim 30, wherein the machine readable instructions, when executed, cause the machine to perform a query on a rule database to determine a preference for one of the two or more corrective procedures.

32. An article of manufacture as defined in claim 23, wherein the machine readable instructions, when executed, cause the machine to determine a customer impact of the at least one corrective procedure.

33. An article of manufacture as defined in claim 32, wherein the machine readable instructions, when executed, cause the machine to select the at least one corrective procedure having the lowest customer impact.
