QoE Metrics Reporting: M1 Provisioning - reportingInterval shall be greater than zero

[dsilhavy]

Description

According to TS 26.512 Table 7.8.3-1 the reportingInterval shall be greater than zero:

The time interval between successive metrics reports. The value shall be greater than zero. If not specified, a single final report shall be sent after the media streaming session has ended.

This requirement is not reflected in TS26512_M1_MetricsReportingProvisioning.yaml

reportingInterval: $ref: 'TS29571_CommonData.yaml#/components/schemas/DurationSec'

Suggested Solution

One solution for this is to add a the following to the yaml definition:

minimum: 0
exclusiveMinimum: true

Rel-17 fix will require a formal Change Request, but @davidjwbbc will provide a temporary workaround.

• TS 26.512 (OpenAPI YAML change only)
  • Rel-16: Won't correct because 5G-MAG's Reference Tools implementation uses Rel-17 as a starting point.
  • Rel-17: CR0069 "[5GMS3, TEI17] Metrics reporting corrections" in S4aI240047.
  • Rel-18: Changes to be handled directly in TS 26.510 V1.2.1.
