OSC SMO Meeting Series: Reminder from previous weeks:
- OSC SMO calls now move to its own time slot - Thursdays
- See OSC RSAC Calendar: https://wiki.o-ran-sc.org/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.
- See OSC SMO Project meeting notes
NOTE: DST Changeover in coming weeks!
- Keep a close eye on the calendars!
OSC Project roundup:
News from OSC TOC call this week
- https://wiki.o-ran-sc.org/display/TOC
- We all remain totally confused about copyright..... will update when we know more
- Integration project PTL election ongoing
NONRTRIC (John Keeney)
- Work examining ONAP Control Loops as a basis for rApps in OSC ... looking promising
- Still have alot of work to do, e.g. packaging & distribution, but working away
- ONAP A1 Policy Management: Istanbul JIRA tickets to be closed before release date!
- Short introductory-level presentation at ONES 2021
SIM (Alex Stancu)
- Addressing in SMO deployment (see below) (Use hostname, not ip:port)
OAM (Martin Skorupski)
- Working on a basis for an O-RAN topology model
- Could be reused in O-RU use case.
- N.K. Shankaranarayanan Does O-RAN Topology include O-RU?
- Ref discussions on ONAP Topology modelling, including Andy Mayer
- N.K. Shankaranarayanan Ref discussions in O-RAN WG1 (Cagatay - AT&T)
- Not including Core Network.
- Issues:
- No agreed model, and even if there was it would not suit most peoples' requirements - everyone wants different topology models for their requirments.
- Very hard to keep any complete topology model populated & synchronized
- Too many layers to have a complete model ... and layering is not necessary accurate.
- Must be model-driven.
- A model that cannot be populated is useless!
O-DU (HariomGupta(HCL))
- Hariom GuptaStill figuring out if 3GPP Yang model can be used.
- JIRAs created for cells & VES measurement events
OPS-5G (David McBride, Doug Evans)
- See discussions 2 weeks ago
- Introductions:
- Andy Leidy, Arnold Alvarado, Douglass Evans (USN), Louis Raspberry, Neil Hoff, Ryan McAllister
- Note session at ONES summit
- Martial: Will the recordings/slides be available? (Think recordings appear on youtube in a few weeks)

- Scripts
- Testing
- Trying to reduce footprint
- Testing O-RU/O-DU/Topology-Server deployment
- VES Collector configuration with SDNC
- Pull request coming soon (this week?) for wider review & comments.
- John Keeney & Xue Gao working together on A1 deployment ... perhaps use existing test suite to avoid having to do new tests?
- John Keeney We are working on modularizing NONRTRIC helm charts, which may affect work here ... ...
- Will also look carefully at the current versions in SMO deployment ... Lots of progress already made!
- Plan to evolve when modular helm charts are available
- Will also look carefully at the current versions in SMO deployment ... Lots of progress already made!
Q&A
Copyright & Licensing
- SCCL: Any open source project can reuse SCCL artifacts - if they abide by by process for that license
- Note SCCL is not an opensource license!
- ONAP may want examine/reuse? the work in OSC for supporting SCCL?
- Long discussion about 3GPP licensing:
- Open/Public != OpenSource != Free
- Try to keep functions model-driven as a much as possible so loosely coupled from copyrighted specs/model, so specs are not reproduced/re-distributed.
- But this is not possible for the actual function encoding the model (e.g. a netconf server & Yang model) or function simulators/emulators, or POCs
- We see no clear path forward for this very long running issue.
- We need to be conservative until we have clear guidance / path forward.
- Unwilling to risk copyright or IPR infringement
- Likely a common-sense reuse approach is possible - with no commercial aspect involved - but we cannot assume this.
