OSC Project roundup:

News from OSC TOC call last week

• https://wiki.o-ran-sc.org/display/TOC#ORANSCTechnicalOversightCommittee(TOC)
  • Last week's TOC (Thursday):
    
    • Some discussion about marketing wrt O-RAN Alliance (Communication and Events Advisory Group (CEAG))
      
      • e.g. https://lists.o-ran-sc.org/g/toc/message/947
      • Not clear how this aligns with the reality of the engagement levels within OSC.
    • OAI & OSC collaboration is making some progress
    • Some progress in Super Wireless RAN Blueprint - e.g. refer to work in Taiwan lab
    • Will try (with RSAC) to do I release planning across projects into usecaes(?) , and  reporting/progress to TOC will follow these...
      • Most discussion/planning needed ... ?
  • This week's TOC (in 2 days):

NONRTRIC (John Keeney)

• Work ongoing:
  
  • RAN PM functions - tidying up & re-releasing in maintenance release.
    • Working with AIMLFW project: Joseph Thaliath to use newer versions
  • Making good progress on rApp manager. More in coming weeks
  • 3PP dependency updates & addressing vulnerability
  • OpenAPI-first in A1-PMS & ICS
    • Change from code→openapi→docs to openapi → code-stubs & docs
    • To better align with R1 specs as they mature
    • To improve expressivity of docs etc.
  • Issue with test framwwork
    • underscore in URI hostnames - introduced by docker-compose (v1)
  • Some changes in A1-Mediator in near-RT-RIC plt in H-Release.

O-DU Vidhu Shekhar Pandey)

• No update this week

OSC Integration / INT (James Li )

• Suggestion from RSAC to identify end-to-end flows
  • Want to at least start with some pairwise-interactions  e.g.
    • OAM & NONRTIRC & SIM & AI-ML
      
      • Possible example: File-based PM
        • Already mostly working ..
      • Possible example: SIM (O1) →NONRTRIC (PM) →NONRTRIC (rApp) → NONRTRIC (A1) → SIM/Nearrtric/O-DU  ??
        • Already have most of this for the O-DU slice assurance usecase - but probably needs to be redone.
      • Possible example: NONRTRIC (PM) → AIML(training & MLModel in rApp) → NONRTRIC (rApp)
        • Most of the parts are there ...
        • Could roll into the O-DU use case above?
      • Some sample pictures to help with this
        • https://docs.o-ran-sc.org/projects/o-ran-sc-nonrtric-plt-ranpm/en/latest/overview.html#data-flow
