Abstract

A system for monitoring tElephone NUmber Mapping (ENUM) performance is disclosed. A system that incorporates teachings of the present disclosure may include, for example, an ENUM system having a subsystem to monitor one or more operations of the ENUM system, and generate a fault notice responsive to detecting one or more faults in the operations monitored. Additional embodiments are disclosed.

Claims

1. A computer-readable storage medium, comprising at least one among a group of computer instructions for:

monitoring a response time to queries submitted to a Telephone Number Mapping (ENUM) system by one or more network elements of an IP Multimedia Subsystem (IMS) network;

monitoring a throughput of queries processed by the ENUM system;

monitoring a maximum response time to queries submitted to the ENUM system;

monitoring a minimum response time to queries submitted to the ENUM system;

monitoring an average response time to queries submitted to the ENUM system;

monitoring utilization of resources of the ENUM system; and

monitoring test queries submitted to the ENUM system.

2. The storage medium of claim 1, comprising computer instructions for comparing each of one or more results derived from at least one of said monitoring steps to a corresponding expectancy threshold.

3. The storage medium of claim 2, comprising computer instructions for asserting a fault notice responsive to one or more faults detected from at least one of the one or more results exceeding its corresponding expectancy threshold.

4. The storage medium of claim 3, comprising computer instructions for submitting the fault notice to a service agent managing operations of the ENUM system.

5. The storage medium of claim 3, comprising computer instructions for mitigating operations of the ENUM system according to the fault notice.

6. The storage medium of claim 3, comprising computer instructions for redistributing resources of the ENUM system to counteract one or more effects caused by the one or more faults.

7. The storage medium of claim 6, wherein the resources comprise at least one among one or more zones, one or more domain name service (DNS) servers, and one or more lightweight directory access protocol (LDAP) servers.

8. The storage medium of claim 1, wherein at least one of the one or more network elements of the IMS network comprises a Serving Call Session Control Function (S-CSCF), and wherein the storage medium comprises computer instructions for:

directing the S-CSCF to perform one among the aforementioned monitoring steps with the ENUM system; and

receiving from the S-CSCF one or more results associated with the monitoring step performed by the S-CSCF.

9. The storage medium of claim 1, wherein the computer-readable storage medium operates in at least one among the ENUM system, and the one or more network elements of IMS network.

10. A Telephone Number Mapping (ENUM) system, comprising a subsystem to:

monitor one or more operations of the ENUM system; and

generate a fault notice responsive to detecting one or more faults in the operations monitored.

11. The ENUM system of claim 10, wherein the subsystem performs at least one among:

monitoring a response time to queries submitted to the ENUM system by one or more network elements of an IP Multimedia Subsystem (IMS) network;

monitoring a throughput of queries processed by the ENUM system;

monitoring a maximum response time to queries submitted to the ENUM system;

monitoring a minimum response time to queries submitted to the ENUM system;

monitoring an average response time to queries submitted to the ENUM system; and

monitoring utilization of resources of the ENUM system.

12. The ENUM system of claim 10, wherein the subsystem compares each of one or more results derived from the operations monitored to a corresponding expectancy threshold.

13. The ENUM system of claim 12, wherein the subsystem asserts a fault notice responsive to one or more faults detected from the one or more results exceeding its corresponding expectancy threshold.

14. The ENUM system of claim 13, wherein the subsystem submits the fault notice to a service agent managing operations of the ENUM system.

15. The ENUM system of claim 13, wherein the subsystem mitigates operations of the ENUM system according to the fault notice.

16. The ENUM system of claim 13, wherein the subsystem redistributes resources of the ENUM system to counteract one or more effects caused by the one or more faults.

17. The ENUM system of claim 16, wherein the resources comprise at least one among one or more zones, one or more domain name service (DNS) servers, and one or more lightweight directory access protocol (LDAP) servers.

18. A network element of an IP Multimedia Subsystem (IMS) network, comprising a controller element to monitor operations of a Telephone Number Mapping (ENUM) system.

19. The network element of claim 18, wherein the network element corresponds to at least one among Serving Call Session Control Function (S-CSCF), Interrogating CSCF (I-CSCF), a Proxy CSCF (P-CSCF), a Home Subscriber Server (HSS), and an Application Server (AS).

20. The network element of claim 18, wherein the controller element performs at least one among:

monitoring a duration to receive a response from the ENUM system after submitting an E.164 number translation query to the ENUM system;

monitoring a throughput of queries processed by the ENUM system;

monitoring a maximum response time to queries submitted to the ENUM system;

monitoring a minimum response time to queries submitted to the ENUM system;

monitoring an average response time to queries submitted to the ENUM system; and

monitoring utilization of resources of the ENUM system.

21. The network element of claim 18, wherein the controller element:

detects a fault from the monitored operations; and

submits a notice associated with the fault to at least one among a service agent of the ENUM system, and a system monitoring operations of the IMS network.

22. The network element of claim 18, wherein the controller element monitors a propagation delay associated with transmitting an E.164 number translation query to the ENUM system receiving a SIP URI therefrom, and translating the SIP URI to an IP address.

23. The network element of claim 22, wherein the controller element generates a notification that identifies an ENUM cluster failure or that requests a check of an ENUM load balancer when no response is received from the ENUM system.

24. The network element of claim 22, wherein the controller element generates a notification that identifies a response time and connection status of the ENUM system.
