OSC Project roundup:

News from OSC TOC call last week

• https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/#ORANSCTechnicalOversightCommittee(TOC)
  • Last week's TOC (Thursday):
    • OSC & OAI collaboration discussion continues.
      • Workshop https://openairinterface.org/joint-osc-oai-workshop-end-to-end-open-source-reference-designs-for-o-ran/ Northeastern University on the 14-15 November 2023
        
  • This week's TOC (in 2 days):
    • Looking for updates for different workstreams

NONRTRIC (John Keeney (Ericsson EST))

• Mostly same as last week:
  • Updating sonar scans and related updates to improve results: making good progress
  • Making good progress on rApp manager.
    
    • Demo 2 weeks ago:
      
      • 2023-09-12 Meeting notes - RApp Manager Interim Demo / Show&Tell Aravindhan Ayyanathan 
    • Adding support for DME integration now. Will demo again in a few weeks.

  • 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.

    • Working now - tested functional equivalence achieved - merging this week. Then more work to follow.
      
  • Some changes in A1-Mediator in near-RT-RIC plt in H-Release.
    • Meeting planned with Near-RT-RIC team tomorrow.
    • Further investigation needed re effects on A1-PMS/ICS & A1-SIM
    • Looks like OSC_v2.1.0. A1-AP (P) profile will b deprecated
      • Will phase out support A1-SIM and A1-PMS in coming releases, when A1-Mediator moves to spec version of A1-AP
    • Need to verify current implementation are fully spec compliant
    • Working on Pairwise test - will be ready as A1-Mediator implementation continues (few weeks)
      • Received info on how to start A1-Mediator in standalone mode - easier to test.

SIM (Alex Stancu)

• Looking at TIM dataset
  
  • Parsing & now a bit easier to use.
  • Very large. Looking for somewhere to share it (Nexus?)

  • Some updates to the UML sequence diagram
    
    • Source: https://gerrit.o-ran-sc.org/r/gitweb?p=oam.git;a=tree;f=spec/pm-streaming & https://gerrit.o-ran-sc.org/r/q/topic:OAM-349 
    • Still work in progress. Please edit and add a review.
    • Hoping to make progress in coming weeks.
  • OAM-349 - Getting issue details... STATUS

ONAP Update (N.K. Shankaranarayanan)

• No update this week

ONAP/OSC Usecases (N.K. Shankaranarayanan)

• Details of using CPS is still ongoing
  
  • Quite complex ...
    • How to interact/integrate SDNR & CPS, e.g. mounted netconf device models, CM notifications
    • VES vs Netconf id mapping is very tricky & must be maintained.
      • Decision: CM handle in CPS is same as Netconf server ID in RANSIM & same of NF ID & same as sourceID in VES message.
  • Also relevant for O-RAN SMO sequence flow work (N.K. Shankaranarayanan)

SMO Deployment

• Ref: RSAC meeting 20/Sep - Slides & video @ 2024 RSAC Meetings 
• Still very unclear how it/dep deployment works & if it is maintained.
• Work from Taiwan Lab should / could be reusable hopefully.
• Meeting with ONAP OOM team tomorrow to iron out technicalities of deploying ONAP functions
  • https://lists.onap.org/g/onap-meetings/viewevent?repeatid=31908&eventid=2003085&calstart=2023-10-04 
    • Wednesday, October 4th, 2023
      2:00pm to 3:00pm (UTC) Coordinated Universal Time
      https://zoom.us/j/96113493781?pwd=cER3aHgvZ1MrNmtXZVV1K0hmQjhnQT09
• There have been updates since OAM function version in it/dep / ONAP worked
  • e.g. VES collector needs to be built (3gpp)
  • e.g. OAM gateway (sdnc, keycloak, dmaap, ves collector are now behind gateway for ease of addressing)
• SIM / topology ... still pretty similar - but very use case specific
• NONRTRIC ... Charts in it-dep/nontric diretory are up to date. charts/configurations in it-dep/smo-intall are a little dated, but not too bad.
• Main question is where does platform stop & use case start .. Alot of the charts/deployment is use case specific.

Disaggregated SMO Flows (N.K. Shankaranarayanan)

• Short update this week
  • Discussion continue in WG1 re AI-ML inclusion in flows.
  • Include service Orchestration function?
  • Include Service Assurance?
• Will come back to TOC Oct 12
• Mapping work in O-RAN WG1 (Disaggregated SMO) to related opensource projects 
  • Strawman for architecture - driven by some candidate usecase flows.
  • Aim for alignment across projects and across diff specs.
  • Aim for common vocabulary etc.
• N.K. Shankaranarayanan working on slides now. See draft slides from previous weeks:
