Abstract

Using alarm data correlation to automatically analyze a network outage. Alarm data for a communications network is received. The received alarm data is correlated to determine a number of users affected by the outage. A set of rules are applied to the correlated alarm data to identify at least one root cause for the outage, and to determine whether or not a trouble ticket will be automatically generated for the outage.

Claims

1. A method for using alarm data correlation to automatically analyze a network outage, the method including:

receiving alarm data for a communications network;

correlating the received alarm data to determine a number of users affected by the outage;

applying a set of rules to the correlated alarm data to identify at least one root cause for the outage, and to determine whether or not a trouble ticket will be automatically generated for the outage.

2. The method of claim 1 wherein the root cause includes at least one of:

a cut or broken communication cable;

an inoperative wireless communication link;

failed network equipment;

a failed satellite link;

or

a natural disaster that disables equipment at one or more central offices or CLLIs or both.

3. The method of claim 1 wherein the set of rules specify that a trouble ticket will be generated if an outage affects at least a predetermined number of users, or if an outage is determined to be a high impact outage, or both.

4. The method of claim 3 wherein a high impact outage is an outage that is caused by at least one failed line card in DSLAM or BRAS equipment, or at least one failed asynchronous transfer mode (ATM) card in an ATM switch, or both.

5. The method of claim 1 further including receiving an incoming call from a communications network user requesting help, and searching a network outage database to locate any stored trouble tickets.

6. The method of claim 5 wherein, if at least one stored trouble ticket is located, the incoming call is transferred to a help desk agent.

7. The method of claim 5 wherein, if no stored trouble ticket is located, an automated diagnostic procedure is initiated with the user over an interactive voice response mechanism.

8. A computer program product for using alarm data correlation to automatically analyze a network outage, the computer program product comprising a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for facilitating a method comprising:

receiving alarm data for a communications network;

correlating the received alarm data to determine a number of users affected by the outage;

applying a set of rules to the correlated alarm data to identify at least one root cause for the outage, and to determine whether or not a trouble ticket will be automatically generated for the outage.

9. The computer program product of claim 8 wherein the root cause includes at least one of:

a cut or broken communication cable;

an inoperative wireless communication link;

failed network equipment;

a failed satellite link;

or

a natural disaster that disables equipment at one or more central offices or CLLIs or both.

10. The computer program product of claim 8 wherein the set of rules specify that a trouble ticket will be generated if an outage affects at least a predetermined number of users, or if an outage is determined to be a high impact outage, or both.

11. The computer program product of claim 10 wherein a high impact outage is an outage that is caused by at least one failed line card in DSLAM or BRAS equipment, or at least one failed asynchronous transfer mode (ATM) card in an ATM switch, or both.

12. The computer program product of claim 8 further including instructions for receiving an incoming call from a communications network user requesting help, and searching a network outage database to locate any stored trouble tickets.

13. The computer program product of claim 12 wherein, if at least one stored trouble ticket is located, the incoming call is transferred to a help desk agent.

14. The computer program product of claim 12 wherein, if no stored trouble ticket is located, an automated diagnostic procedure is initiated with the user over an interactive voice response mechanism.

15. A system for using alarm data correlation to automatically analyze a network outage, the system including:

an alarm analysis mechanism for receiving alarm data associated with a communications network, wherein the alarm analysis mechanism is capable of correlating the received alarm data to determine a number of users affected by the outage, applying a set of rules to the correlated alarm data to identify at least one root cause for the outage, and determining whether or not a trouble ticket will be automatically generated for the outage based upon the identified root cause;

a rules database for storing the set of rules, wherein the rules database is operably coupled to the alarm analysis mechanism;

an alarm database for storing alarm data, wherein the alarm database is operably coupled to the alarm analysis mechanism;

at least one of a user network interface database operably coupled to the alarm analysis mechanism, a network topology database operably coupled to the alarm analysis mechanism, or a telephone number to common language location identifier (CLLI) database operably coupled to the alarm analysis mechanism, wherein the user network interface database stores data associating each of a plurality of user identifiers with one or more corresponding network interface equipment identifiers, the network topology database stores a set of attributes associated with each of a plurality of network elements, and the telephone number to CLLI mapping database associates each of a plurality of respective telephone numbers with a corresponding CLLI; and

a trouble ticket output mechanism operatively coupled to the alarm analysis mechanism and capable of at least one of printing a generated trouble ticket or displaying a generated trouble ticket.

16. The system of claim 15 wherein the root cause includes at least one of:

a cut or broken communication cable;

an inoperative wireless communication link;

failed network equipment;

a failed satellite link;

or

a natural disaster that disables equipment at one or more central offices or CLLIs or both.

17. The system of claim 15 wherein the set of rules specify that a trouble ticket will be generated if an outage affects at least a predetermined number of users, or if an outage is determined to be a high impact outage, or both.

18. The system of claim 17 wherein a high impact outage is an outage that is caused by at least one failed line card in DSLAM or BRAS equipment, or at least one failed asynchronous transfer mode (ATM) card in an ATM switch, or both.

19. The system of claim 15 further including an interactive voice response mechanism for receiving an incoming call from a communications network user requesting help, and wherein the alarm analysis mechanism is capable of searching a network outage database to locate any stored trouble tickets.

20. The system of claim 19 wherein, if the alarm analysis mechanism locates at least one stored trouble ticket, the interactive voice response mechanism transfers the incoming call to a help desk agent.

21. The system of claim 19 wherein, if no stored trouble ticket is located, the interactive voice response mechanism initiates an automated diagnostic procedure with the user.
