E.2 Controlled vocabularies of DASH QoE metrics reporting parameters

26.5123GPP5G Media Streaming (5GMS)ProtocolsRelease 17TS

E.2.1 Reporting parameters for 3GP-DASH metrics

The name space identifier for the controlled vocabulary of DASH QoE metrics is:

urn:‌3GPP:‌ns:‌PSS:‌DASH:‌QM10

The term identifiers in this controlled vocabulary shall be the set of key names defined in clause 10.2 of TS 26.247 [4], using a single forward slash character (‘/’) as the hierarchical separator in the resulting path specifier. In the case of metrics lists, the Entry object shall be omitted from the term identifier path.

EXAMPLE 1: urn:‌3GPP:‌ns:‌PSS:‌DASH:‌QM10#AvgThroughput/numbytes

To select all reportable metrics below a common branch of the metrics hierarchy the relevant terminal path element(s) are pruned from the term identifier.

EXAMPLE 2: urn:‌3GPP:‌ns:‌PSS:‌DASH:‌QM10#AvgThroughput

E.2.2 Reporting parameters for VR metrics

The name space identifier for the controlled vocabulary of VR metrics is:

urn:‌3gpp:‌metadata:‌2020:‌VR:‌metrics

The term identifiers in this controlled vocabulary shall be the set of key names defined in clause 9.3 of TS 26.118 [42], using a single forward slash character (‘/’) as the hierarchical separator in the resulting path specifier. In the case of metrics lists, the Entry object shall be omitted from the term identifier path.

EXAMPLE 1: urn:‌3gpp:‌metadata:‌2020:‌VR:‌metrics#CompQualLatency/Latency

To select all reportable metrics below a common branch of the metrics hierarchy the relevant terminal path element(s) are pruned from the term identifier.

EXAMPLE 2: urn:‌3gpp:‌metadata:‌2020:‌VR:‌metrics#CompQualLatency
