Abstract

The invention relates to a method of and device for service monitoring and a method of and device for service monitoring management. In particular the invention relates to a method of and device for service monitoring of at least one service, and of at least one sub-service associated with the service in which values for service monitoring metric and sub-service monitoring metrics derived from the terminal operational information are monitored and recorded. One or more service monitoring reports, containing service monitoring metric values and sub-service monitoring metric values that are relationally organized to reflect the association between the sub-service and the service, are sent. The invention also relates to a method of and device for service monitoring management in which one or more service monitoring reports, having service monitoring metric values and sub-service monitoring metric values that are relationally organized to reflect the association between the sub-service and the service, are received and stored. The received service monitoring metric values and sub-service monitoring metric values are analyzed with reference to the association between the service and the sub-service to perform service monitoring management. The service monitoring of the claimed invention may be carried out in a terminal or in a proxy or agent service monitoring device.

First claim

The invention claimed is:

1. A method of service monitoring, comprising the steps of:
receiving a service monitoring request to perform service
monitoring of at least one service, and of at least one sub-service associated with the service, in a terminal, wherein for the or each service to be monitored the method comprises the steps of:
monitoring terminal operational information;
recording at least one value for at least one of a service monitoring metric and a sub-service monitoring metric derived from the terminal operational information; and
sending one or more service monitoring reports in respect of a service, wherein service monitoring metric values and sub-service monitoring metric values within the or each service monitoring report are relationally organised reflecting the association between the sub-service and the service.

2. The method as claimed in claim 1 wherein the step of recording comprises recording values for service monitoring metrics in a service record for the service monitoring metrics and recording values for sub-service monitoring metrics in a sub-service record associated with the service record.

3. The method as claimed in claim 1 wherein the step of monitoring further comprises the step of determining the occurrence of a service event requiring the update of at least one service metric value or sub-service metric value; and in the step of recording, a value for at least the metric to which the determined session event relates is recorded.

4. The method as claimed in claim 1 wherein service and sub-service monitoring metric parameters are used in the step of monitoring terminal operational information to determine the occurrence of a service event.

5. The method of service monitoring in claim 1 , wherein the service monitoring metric values and sub-service monitoring metric values within the or each service monitoring report are formed from a combination of respective measured metric values.

6. The method of service monitoring in claim 1 wherein the service monitoring request defines parameters for measurement of the service monitoring metrics.

7. The method of service monitoring in claim 1 wherein the sub-service monitoring metric values within a service monitoring report relate to a sub-service monitoring metric values recorded during a plurality of sub-service sessions.

8. The method of service monitoring in claim 1 wherein a received metric parameter defines a periodic monitoring wait period, and a service event is detected after expiry of a corresponding wait period.

9. The method of service monitoring in claim 1 wherein a received metric parameter defines a threshold for a metric and a service event is detected after the value of the monitored metric crosses the threshold.

10. The method of service monitoring in claim 1 wherein a service event is detected at the start and/or termination of a service session.

11. The method of service monitoring in claim 1 wherein a service event is detected at the start and/or termination of a sub-service session.

12. The method of service monitoring in claim 1 wherein the step of monitoring terminal operational information includes the step of identifying values for the service monitoring metrics or sub-service monitoring metrics from packet inspection of packets relating to the service.

13. The method of service monitoring in claim 1 wherein the step of recording at least one value for a service monitoring metric and/or a sub-service monitoring metric includes the step of identifying values for the service monitoring metrics and/or sub-service monitoring metrics from packet inspection of packets relating to the service.

14. The method of service monitoring as claimed in claim 1 , wherein
in the step of monitoring, terminal operation information is monitored to determine the occurrence of session events of each of a plurality of stages of a user service session;
in the step of recording the values for service monitoring metrics for a stage are recorded in response to a session event of that stage; and
in the step of sending, at least one service monitoring report, containing service monitoring metric values, is sent for each stage of the user service session.

15. The method of service monitoring as claimed in claim 14 wherein the step of monitoring uses packet level terminal operational information to determine the occurrence of session events.

16. The method of service monitoring as claimed in claim 14 , wherein in the step of monitoring, different metric parameters may be used in monitoring a service monitoring metric in at least two stages of the user service session.

17. The method of service monitoring as claimed in claim 1 , wherein in the step of recording values for service monitoring metrics for a stage are recorded in a session record for that service.

18. The method of service monitoring as claimed in claim 14 , wherein the step of recording, the values for service monitoring metrics are recorded for at least two stages of the user service session using a different set of service monitoring metrics.

19. The method of service monitoring as claimed in 14 , wherein the step of recording, the recorded values for service monitoring metrics for a stage are derived from a plurality of metric values during the service session stage.

20. The method as claimed in claim 14 , wherein the stages of a user service session comprise: a session start stage; a service session delivery stage; and a service session termination stage.

21. The method of service monitoring as claimed in claim 1 , further comprising the step of:
forming a terminal service monitoring request from the received service quality monitoring request to request service monitoring of at least one service in a terminal using terminal service monitoring metrics;
sending the terminal service monitoring request to a terminal measurement control in the terminal;
wherein the step of monitoring terminal operational information includes the steps of receiving a service event report from the terminal measurement control; and
wherein the step of recording metric values comprises a step of sending a request for required terminal information; and recording metric values based on the received terminal information.

22. The method as claimed in claim 21 comprising the steps of:
comparing requested service monitoring metrics for a service and reported service monitoring metric values in a service monitoring report for that service to identify missing service monitoring metrics that were requested but not reported; and
determining whether a value for a missing service monitoring metric is available; and
inserting any available missing service monitoring metric value into the monitoring report message.

23. The method as claimed in claim 22 further comprising the steps of:
receiving service monitoring metric data for the service; and
storing the service monitoring metrics for the service in the service monitoring metric store.

24. The method as claimed in claim 23 wherein
the step of receiving requested service monitoring metric data for the service comprises the steps of:
receiving a service monitoring request, containing service monitoring metrics, in respect of the service;
determining service monitoring metrics for the service from the service monitoring request.

25. A device for service monitoring, comprising:
a receiver to receive a service monitoring request to
