Method and apparatus for quality of service monitoring of services in a communication network
First Claim
1. A method of quality of service monitoring a service in a communication network, comprising:
- sending to a plurality of terminals a first set of quality report configuration parameters relevant to the service;
collecting a first set of terminal service session reports, wherein each terminal service session report included in said first set of reports was generated by one of the plurality of terminals using the first set of quality report configuration parameters;
detecting a degradation of service quality in the communication network based on the first set of terminal service session reports; and
identifying a factor that is potentially causing the degradation of service quality in the communication network, wherein identifying the factor comprises;
selecting a candidate factor;
selecting a second set of quality report configuration parameters based on the selected candidate factor;
sending to the plurality of terminals the second set of quality report configuration parameters;
collecting a second set of terminal service session reports, wherein each terminal service session report included in said second set of reports was generated by one of the plurality of terminals using the second set of quality report configuration parameters; and
evaluating whether the candidate factor is a potential cause of the service quality degradation based on the collected second set of terminal service session reports.

Abstract
The present invention relates to a method of quality of service monitoring of at least one service in a communication network. The method comprises a first and a second modes. The first mode comprises detecting degradation in quality of service in a communication network by selecting (80) a set of terminal service sessions for providing terminal service session reports; collecting (82) terminal service session information from the selected terminal service sessions; and determining (84) the quality of service in the communication network from the terminal service sessions monitored in the first mode. The second mode, being entered when a degradation of service quality in at least part of terminal service sessions is detected (86), comprises identifying at least one factor causing degradation of service quality in the communication network in steps of determining (88) at least one potential factor associated with terminal service sessions having degraded service quality as a candidate factor potentially causing the observed service quality degradation in at least part of the terminal service sessions; collecting (90) terminal service session information from terminal service sessions associated with at least one candidate factor; and evaluating (92) collected terminal service session information for service sessions associated with a candidate factor to identify whether the candidate factor is a cause of service quality degradation.

18. An apparatus for quality of service monitoring in a communication network, the apparatus comprising:
-
a transmitter; a receiver; data storage; and a data processing system, comprising one or more processors, coupled to the data storage, the transmitter and the receiver, wherein the data storage stores computer instructions for programming the data processing system to; employ the transmitter to send to a plurality of terminals a first set of quality report configuration parameters relevant to a service; employ the receiver to collect a first set of terminal service session reports, wherein each terminal service session report included in said first set was generated by one of the plurality of terminals using the first set of quality report configuration parameters; detect a degradation of service quality in the communication network based on the first set of terminal service session reports; and identify a factor that is potentially causing the degradation of service quality in the communication network by; selecting a candidate factor; selecting a second set of quality report configuration parameters based on the selected candidate factor; sending to the plurality of terminals the second set of quality report configuration parameters; collecting a second set of terminal service session report, wherein each terminal service session report included in said second set was generated by one of the plurality of terminals using the second set of quality report configuration parameters; and evaluating whether the candidate factor is a potential cause of the service quality degradation based on the collected second set of terminal service session reports.
