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!

• See above & 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 somewhat confused about copyright..... will update when we know more
• Integration project PTL election completed: James from CMCC elected!

NONRTRIC (John Keeney)

• Working mainly on Helm chart updates ... see also below

SIM (Alex Stancu)

• Topology service available!
  
  • TAPI topology simulator. (See below)
  • Image: nexus3.o-ran-sc.org:10004/o-ran-sc/smo-nts-ng-topology-server:1.3.6

OAM (Martin Skorupski)

• Working on helm charts.
• Struggling with licensing issues. (See below)

O-DU (Hariom Gupta )

• Hariom GuptaStill figuring out if 3GPP Yang model can be used / implemented. 

Topology Models: 

• No model suits everyone
• TAPI model is quite abstract / domain independent - basically functions & endpoints ( edge-point, interface, logical termination point, connection points etc)
  • Simulator/Usecases considers CUs, DUs, RUs, & their location
  • Topology model loaded/configured at start time (JSON/XML). Made available using TAPI Netconf model. (Netconf server)
• @All - Discussion:
  • Cell/Neighbour-Relation? Not explicitly modeled ... but would it be a function, connection, logical grouping, parameter?
    • All valid for different usecases! Everyone has their own topology model for their own use case!
  • TAPI is very abstract, so a good starting point for more specific topology models.
  • Discussion continue in ONAP modelling work.
• Is ANR (Automated Neighbor Relations) supported in O-RAN?
  • Not O-RAN specific ... feature/usecase that can be implemented in various ways in 4g, 5g, etc ... Centralized, Distributed, Hybrid, in xApp, etc....

ONAP SMO deployment options

• Sebastien: Pull Request on OSC it/dep repo for existing SMO Deployment package - will overwrite existing version
  
  • https://gerrit.o-ran-sc.org/r/c/it/dep/+/6860
  • It very big though so will take some time.
  • John Keeney & Sebastien should talk offline about changes from original, and proposed changes to NONRTRIC helm charts (also in progress)
  • Should also now include new INT PTL
• David Johnson Mini deployment in POWDER lab seems to be working well! Will also look at SMO Deployment here & feedback.
• Sebastien: Also working on OOM changed (DCAE/VES Collector config for SDNC)
  
  • https://gerrit.onap.org/r/c/oom/+/125150
• Sebastien: Also has an issue with O-RU-use case App ... issue with HTTPS .... Python issue?

Copyright & Licensing

• SCCL:
  • Recent "Special TOC Call" about licensing, but was not SCCL recorded
    • https://www.o-ran.org/sccl
  • SCCL does not address 3GPP license issue - Issue continues as before
    • O-RAN Alliance will try persuade 3GPP to use SCCL ... but progress stalled.
  • SCCL is currently only for O-RAN Alliance material - to be agreed to by anyone using/redistributing these specs
  • OSC is a first mover to put procedures in place
  • SCCL is copyright only - IPR licensing is a seperate issue and not addressed
  • SCCL is not an open-source license
  • We are making some progress understanding SCCL (but we're not there yet!)
  • Can SCCL specs be redistributed freely?: No.
• 3GPP:
  • Surely there is potential to request a PoC/Demos/non-Commercial derogation from 3GPP
  • We need to keep pushing.
  • Tracy Van Brakle IIRC 3GPP does allow use for demos/poc/exhibitions ? Will check up on this! This should be enough for our requirements. 

Simulators

• N.K. Shankaranarayanan The RANSIM work in ONAP is making good progress!  (Ref Krishna in SON, Slicing & OOF in ONAP)
  
  • Tracy Van Brakle N.K. Shankaranarayanan Should all these simulators be consolidated?
    • They could be more aligned, but probably should not be "merged" - they have different priorities / simplifications embedded - by design! 
    • But they do have some shared/shareable functions/requirements, so some alignment might be helpful.
    • Tracy Van Brakle Is there something like Mininet for O-RAN/3GPP/RAN? Maybe academic contributors would be best suited to help here
