OSC SMO Meeting Series: Reminder from previous weeks:

• OSC SMO calls now move to its own time slot - Thursdays
  • See OSC RSAC Calendar: https://lf-o-ran-sc.atlassian.net/wiki/display/RSAC/calendars
  • See also OSC Meetings calendar: https://lists.o-ran-sc.org/g/main/calendar
• (Note this meeting to open to anyone, including non-ORAN members)
• We will maintain this slot for ONAP Alignment, and try flag issues/question to/from SMO meetings.

OSC Project roundup:

News from OSC TOC call this week

• https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/#ORANSCTechnicalOversightCommittee(TOC)
  • Note Time change for TOC calls from May 5th onward
    • +1 day & 1hr. Thursdays  (Thursday 9AM EST)
    • Timeslot is currently used by RSAC/SMO (RSAC/SMO will take the timeslot originally used for TOC)
    • Keep watching calendar as updates are ongoing  
      • https://lists.o-ran-sc.org/g/main/calendar
  • OTF readout likely will happen next week at RSAC call (Note changing time for RSAC call - moved to Wednesday - taking the old OSC TOC timeslot)
  • VIAVI presented plans for RAN simulator/emulator & extensions for future use cases - particularly the mMIMO use case.
    
    • Binary distribution will be provided, with some scripts & tests provided.
    • (Emulator was previously used to generate data for HCL for ML training (xApp?) and also for E2 simulator https://gerrit.o-ran-sc.org/r/admin/repos/sim/e2-interface-data)
  • New ns-3-based E2/RAN simulator contribution proposed by Northeastern University (with inputs from Mavenir & University of Padua)
    
    • Will act as an E2 simulator for near-RT-RIC as an ns-3 5G simulations using OSC E2 Simulator
    • License: GPL
    • New repo required.

NONRTRIC (John Keeney (Ericsson EST))

• Finalizing ONAP J release for A1 Policy Management Service
• Working towards ONAP Kohn release requirements
• Repo moves almost complete.
• And, as per last week:
  • Working on e2e PM data - making it available over pre-R1 DME (OSC NONRTRIC) Information Coordination Service)
  • Working on PoC Service Exposure - with a view towards R1
    • Examining 3GPP CAPIF spec
    • Will update more as this matures - still very early - hopefully a demo in coming weeks (Kevin Timoney )
• See discussion on ONAp use cases below.

SIM (Alex Stancu)

• Northeastern University (& Mavenir, Padua University) approved to contribute an E2 simulator plugin for NS3.
  • Discussed at TOC this week (see above)

OAM (Martin Skorupski)

• Looking at Prometheus for O-Cloud metrics (With Grafana? for visualization)
  • Possible to add to the base OSC SMO integration package?
• Examining O-Cloud specs & relevance for OAM. G release most likely.

O-DU (Hariom Gupta Vidhu)

• VES event production & fault event validation (schema reference): Working now
  
  • Will give a review soon
  • Martin Skorupski Note Std-defined (FM?) messages are not yet visible in SDNR ODLux - will add soon
    • Maybe add support for different Std-defined events

OSC Integration / INT (James Li )

• OTF workshop planned for RSAC call next Wed (see TOC vs RSAC time changes above)
  • OTF installed in Bedminster Lab

RSAC/SMO (David Kinsey [AT&T])

• No update

Copyright Update (N.K. Shankaranarayanan)

• Need to get feedback back to Magnus Buhrgard about plans to use 3GPP artifacts in ONAP
• Some discussion at O-RAN WG10 call about O-RAN→ 3GPP LS - but OSC out of scope there.
  • Probably should aim for more liaison OSC → 3GPP?

ONAP Use Cases Update  (N.K. Shankaranarayanan)

• Working on SON use case requirement for K release
  • Moving from O1-based to A1-based
    • rApp would likely need to be aware whether it is using A1 or O1 - Currently R1 plans for 2 separate logical functions(?)/service(?) for O1 vs A1 ... maybe later R1 might have a more abstract (e.g. Intent) interface ?
    • Updating ONAP NetSIM for A1 etc. & plugable simualtor use-case logic
  • Hope to rApp-ify & extend the Control-loops ("Automation Compositions") used  - will work with ONAP Policy team Liam Fallon )
    • Should have a Call soon between SON team, N.K. Shankaranarayanan, Liam Fallon & John Keeney (Ericsson EST)
    • Currently messages are DMaaP (Control Loop messages) ... Will that work?
      • Will work for A1 PolicyManagementService (has a DMaaP NBI) - but this is not very R1-ey
  • Still have a few weeks - but need to make progress 

Q/A

• None this week - have a good week!
