QoE Metrics Report: Final round of metrics reporting #28

Closed dsilhavy closed 5 months ago

dsilhavy commented 1 year ago

Feature description Section 5.5.3 of TS26.501 defines the 5GMSd AF-based reporting procedure. Step 19 and 20 require obtaining the latest metrics measurements from the Media Player and sending them to the 5GMSd AF upon the termination of media playback.

Suggested solution Push the metrics from the Media Stream Handler to the Media Session Handler once playback is finished or a new streaming session is started. For that reason, we need to persist some parameters in the Media Stream Handler, namely the reportPeriod and the metrics to be reported for each scheme.

As an alternative, we are currently triggering all playback requests using the Media Session Handler sending an IPC message to the Media Stream Handler. In theory, this message could also trigger a final metric report as a response. However, this would not cover the case in which playback ends regularly and no new playback session is started.

Implemented according to the suggestion above in #56
