News from OSC TOC call last week

https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/#ORANSCTechnicalOversightCommittee(TOC)
- Last week's TOC (Thursday):
  - No call last week
  - Discussion at O-RAN F2F meetings:

NONRTRIC (John Keeney (Ericsson EST))

Goodbye to Henrik Andersson one of our first & most prolific contributors for the past 4 years. He'll be missed
G Maintenance Release - small bug fixes etc
- Image preparation & releases completed. No very significant updates from G Release
File-based PM data → InfluxDB
- Early demo at AI-MLProject this week
  - https://gerrit.o-ran-sc.org/r/c/nonrtric/+/10477
- Will demo here in coming weeks when a little more stable
- Uses tool-chain demonstrated for file-based PM parse filtered & streamed to rApps - now extended to also store in influxDB.
  - G-Release: Demonstration: "PM Collection & Delivery to rApps" Demo
Inference Services in rApps
- Extension to ONAP ACM functions - added a 'KServe Participant'
- Now supports ML Inference services in ACM Apps (rApps) - so they are LCM'ed in a common way - along with other rApps components/elements
- Will demo in a short while when function is a bit more stable / cleaner.
- https://gerrit.onap.org/r/c/policy/clamp/+/133263
- https://docs.onap.org/projects/onap-policy-parent/en/latest/clamp/clamp.html

- Release H Planning continues:
  - (R1) Service Exposure & Management
    - CAPIF Aligned Service Registry
    - Secured/Sandbox execution environment
    - Controlled access & exposure of service to/from rApps
  - (R1) Data Management & Exposure
    - Previous focus on PM data - but will extend to other use cases too
    - Aim to work with AIML project for Training (and Inference ?) data access
  - rApp Management
    - Built on ONAP “Automation Composition” model & platform to implement rApp use cases
      - rApp-specific extensions needed
    - Packaging, Onboarding & Orchestration of rApps
      - rApp-specific packaging & Onboarding
        Aim to align with / inform ongoing work in O-RAN (& OSC) about Common App packaging & Onboarding.
      - (rApps with & without µService)
    - Overlap with Service Exposure work to examine role of an rApp Manager to support controlled exposure & LCM of µService and non-µService parts of an rApp
  - Continued A1-Policy & A1-Enrichment-Information evolution (& R1-A1)
    - A1 Spec evolution
    - A1-Policy work in ONAP (continues in ONAP London) - candidate for R1-A1(P)
    - A1-EI management as part of DME - candidate for how to include A1-EI in R1-DME
  - Sample use cases (rApps)
    - Requirements Drivers for rApp/R1 development
    - High degree of cross-project integration activity
  - Testing, Maintenance & Housekeeping
    - Function Test & Integration Test environment,
    - Support integration, deployment & configuration of SMO/Non-RT-RIC related functions & usecases in OSC Integration env.
    - Project coordination, Documentation, Delivery, Reporting, Cross-project alignment, Community demos, O-RAN Standardization support, etc.

SIM (Alex Stancu)

Continuing discussions with Northeastern Univ re ns3 simulator plugin - E2 Alignment
Looking at ves File Ready event, to be O1 compliant
- John Keeney (Ericsson EST) Alex Stancu We should talk about linking up & demoing O1-Simulator → rApp flow mentioned in NONRTRIC section above.
  - Could look at extending simulator to continuously/periodly expose PM files. ... But need some samples ... maybe with random data?
- Some discussion on sample PM files ... Does anyone know where we could find an O-RAN O1 compliant sample file?
  - Still compliant with 3GPP DU/CU ... Maybe an operator might have a some samples

OAM (Martin Skorupski)

Updating OAM with latest O1 specs.

O-DU (Hariom Gupta Vidhu)

No Update

OSC Integration / INT (James Li )

Working on XTesting for xApp onboarding etc
Examining how to work with INF project re O2 interface, & overlap with Tacker team in SMO.
