• Reminder from previous week:

  • 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

  • (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.

• Meeting invites etc.

  • @John Keeney (Ericsson EST) to update meeting invites.

  • @Konrad Bańka To check if a postcode is needed - or just be signed into zoom.

OSC Project roundup:

NONRTRIC (@John Keeney (Ericsson EST))

• No major update.

• Still training & initial prototyping around rApp execution platform - k8s based.

SIM (@Alex Stancu)

• Ongoing work with OTF integrating E2 simulator

• Some email exchanges with Facebook RAN simulator

OAM (@Martin Skorupski)

•  Still discussing topology in ONAP: Abstract Topology Model

  • Good discussions with @Tony Finnerty

  • Agreeing on terminology & scope

• O-RAN specs from "November train" now available from O-RAN website

  • Ref O-RU & O-DU yang models - Copied to O-RAN gerrit (under review) - (note O-RAN SCP license) 

    • WG4 O-RAN RU Fronthaul M-Plane: https://gerrit.o-ran-sc.org/r/c/scp/oam/modeling/+/5706

    • WG5 O-RAN DU O1: https://gerrit.o-ran-sc.org/r/c/scp/oam/modeling/+/5705

  • @Martin Skorupski Gathering & providing feedback to WGs.

ONAP - OSC:

• @Lasse Kaihlavirta @John Keeney (Ericsson EST) ORAN ONAP CSIT

  • CSIT test run as expected now.(Tanks to @Lasse Kaihlavirta)

  • Still need to confirm test environment is stable - if issues in coming weeks we will escalate to LF.

  • @Lasse Kaihlavirta wants to discuss futher with @Björn Magnusson @Former user (Deleted)  - will do offline.

  • Some concern about how long tests may take to run. Will monitor for a while and adjust if needed.

• @Lasse KaihlavirtaWhat will A1 / R1 look like? (Still being defined in O-RAN WG2 - so everything until then is just prototyping!) 

  • @John Keeney (Ericsson EST) Work is ongoing in OSC - likely to be some time before we have a proposal, and then any proposal is subject to change once R1 is specified

    • Would like all R1 operations to/from rApps to traverse through some form of API gateway - to enforce isolation & R1 compliance.

    • Current plan for A1 Policy is that A1 PMS should be close to R1 exposure for A1 (TBC) - so initially we will just expose A1 PMS NBI.

      • Likely to have some URL translation though AP1 gateway (e.g. url prefix etc)

    • Need to be careful to avoid ONAP service becoming de-facto R1. @All - Please bring your priorities/suggestions for R1 to WG2 as early as possible.

• @Pawel Slowikowski Samsung A1 use case demonstrated late last year.

  • Ref: 2020-07-29 Meeting notes (SDN-R)

    • Demonstrates UE Handover closed loop - extends ONAP & OSC simulators & A1 policy functions, some DCAE microservices

  • Contributing the code to ONAP INT project in coming weeks.

  • @Pawel Slowikowski Unlikely rApps will be DCAE microservices - more likely K8s deployments - but DCAE is starting to move this way too.

  • @John Keeney (Ericsson EST) Encourage to look at Control Loop work in ONAP (proposed as a new ONAP Project in Istanbul release) https://wiki.onap.org/display/DW/TOSCA+Defined+Control+Loop%3A+Architecture+and+Design

  • @Pawel Slowikowski Hopefully this work will continue in ONAP INT (maybe a usecase?) in coming releases. Currently PoC only - Don't plan to promote as a full ONAP use case.

  • @John Keeney (Ericsson EST) @Pawel Slowikowski Need to ensure alignment between OSC & ONAP

• @Hariom Gupta (Deactivated) O-RU Closed loop use case - O-DU startup part.

  • Successfully Tested using Netopeer-cert and test certs. Will test will new certs from Felix if/when they are available (@Alex Stancu also testing with newly created certs)

  • Regarding Yang files from WG5 - has LOTS of dependencies on 3GPP. @Martin Skorupski @Hariom Gupta (Deactivated) Will work together to use just the use-case necessary parts. Ref OSC SMO/RSAC call tomorrow.

• @Vidhu (Deactivated) Setting up test env to work toward O-DU set up. 

  • @Martin Skorupski to send sample for PNF  registration VES event

• @Swaminathan S working with @Former user (Deleted) about FM in SON use case.

  • updates to follow
