  • This week's TOC (in 2 days):

NONRTRIC (John Keeney)

• Quick Demo: Docker Compose & Scripts to run RAN PM use-case (Kevin Timoney)
  • See below

• Updating sonar scans and related updates to improve results
  • Requires a couple of tickets etc in LF ... but making good progress
• Making good progress on rApp manager.  (Hope to demo in a couple of weeks)
  • 2 weeks maybe? (Aravindhan Ayyanathan) 
• 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 expressiveness of docs etc.

• Some changes in A1-Mediator in near-RT-RIC plt in H-Release.

  • Further investigation needed re effects on A1-PMS/ICS & A1-SIM

  • Will return to this next week.
  • Need to reply to Thoralf Czichy to give an update. (ref INT project update below)

SIM (Alex Stancu)

• Changing datastore/models etc to python (Netconf server stays in C)
  
  • Will hopefully make contributions & extension a lot easier
    • e.g. especially websockets for streaming etc.
• I-Release planning

OAM (Martin Skorupski)

• Request (from RSAC) to make proposal for RAN PM streaming
  • Proposal for a pragmatic draft model
    • Based on 3GPP XSD for PM data
  • PM Streaming 
  • John Keeney Working on a version of the PlantUML to include NONRTRIC RanPM functions
  • Martin Skorupski Would like to reuse as much as possible of NONRTRIC RanPM functions 
    • Easiest way might be to put collected/streamed XML (or JSON) into S3/Minio and can then hopefully reuse existing functions.
    • Only new part is Stream terminator.

OSC Integration / INT (James Li )

• Energy Savings usecase:
  • Still trying to understand Energy saving rApp - discussions started with SUNIL SINGH discussed at RSAC & RIC-PLT/-APP meeting earlier today
    • Not sure who has resources to work on the rApp
      • John Keeney Would like to keep aligned about how the rApp is structured, packaged, LCM'ed, on-boarded, Interfaces used (e.g. SME, DME) etc.
  • N.K. Shankaranarayanan would like to keep informed about progress here (and other usecases) - Needs to help with end-to-end flows etc (also Alex Stancu was volunteered for this job) .
