CR 26.517 CR#0038 – OpenAPI YAML Corrections (5MBP3)

Source: BBC | Meeting: SA4#135bis-e | Category: A (mirror) | Release: Rel-18

Summary

  • Problem: The cancelled property defined in the normative TS 26.517 specification for ServiceScheduleDescription was missing from the OpenAPI YAML schema in Annex A.2.1 (TS26517_MBSUserServiceAnnouncement.yaml).
  • Impact: Without this property, cancellation of MBS User Service Announcements is not possible via the API.
  • Fix: Adds the missing cancelled boolean property (default: false) to the ServiceScheduleDescription schema object in the YAML.
  • Additional housekeeping: Copyright year updated (2024→2026), spec version reference updated in externalDocs (V18.3→V18.6.0), and YAML version field bumped to 2.1.01.
  • Affected clause: A.2.1 of TR 26.517 (MBS User Service Announcement schema).
  • No other specs affected (test specs, O&M, other core specs not impacted).
