• 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.

OSC Project roundup:

NONRTRIC (John Keeney (Ericsson EST))

• Hoping to present some slides to RSAC tomorrow (rApps in E-Release) - postponed from last week
  
  • https://lf-o-ran-sc.atlassian.net/wiki/display/RSAC/RSAC+Meetings https://lf-o-ran-sc.atlassian.net/wiki/display/RSAC/calendars 
  • Will focus on rApp platforms & R1 Service exposure/gateway/delivery
• Wrapping up M4 issues for A1 Policy functions in ONAP
• Experimenting with making DMaaP messages available to rApps over the Service Exposure function via the Information Coordination service
  • e.g. VES information from the RAN
  • Possible precursor for R1 data coordination functions until they crystalize in the specs
• Will follow up with LF about making Helm charts available in a chart repo ...
  • https://jira.linuxfoundation.org/plugins/servlet/theme/portal/2/IT-22586
  • https://jira.linuxfoundation.org/browse/RELENG-3837
• Struggling with a issue with Jenkins verify tasks in OSC (Docker verify task fails ... working through candidate solutions with LF ... possible environment issue)

SIM (Alex Stancu)

• Working on call home via TLS in O1 (ofh-mplane) simulator.

OAM (Martin Skorupski)

• Working with O-DU team for yang model (Cell configuration)
  
  • Working toward Slicing assurance closed loop usecase
  • to include TMF apis slice management functions
  • What if Yang models are different? (e.g. O1 vs OFH-Mplane vs simualtor) Which function should handle/isolate this?
• Contacted via N.K. Shankaranarayanan about end-to-end slicing in ONAP for OSC/ONAP alignment
  • currently working at O1/A1 type messages, so haven't gotten down as far as OFH yet.
  • Will bring up at slicing use case call
  • Also ORAN-slicing ↔ ONAP-slicing discussions seem to have stalled ... need to be restarted.

O-DU (Hariom Gupta)

• Vidhu focusing on Yang modules for cell configuration, e.g. which parameters etc.
  • Some parameters already in the hello-world model - reuse, augment or replace?
  • Working with Martin Skorupski
• Slicing assurance use case parameter .. .working with Former user (Deleted)
  • Still figuring which parameters are appropriate. 
• Discussing if PM should be file based on ves-based ... (see below)

News from OSC TOC call this week

• No update
  
  • https://lf-o-ran-sc.atlassian.net/wiki/display/TOC/#ORANSCTechnicalOversightCommittee(TOC)-20210915

VES for PM

• Lack of clarity when to use file-based vs event-based vs stream-based for O1 PM
  • Depends on use case / metric ... probably need multiple for any function
• Ongoing discussions in SMO/RSAC call tomorrow
  • https://lf-o-ran-sc.atlassian.net/wiki/display/RSAC/RSAC+Meetings https://lf-o-ran-sc.atlassian.net/wiki/display/RSAC/calendars 
• Proposal for VES PM event would not be O1 spec compliant right now
  • Discussion should happen in WG10, and likely in 3GPP

CM Notifications - Updates to SDNR

• (Recording @ 00:35:00 - 01:03:06)
• Marcin Wilk, Rafal Wrzesniak  (Samsung)
  • Slides & sample CM-Notification VES event.
    
• StdDefined VES event - using provMnS.yaml - NotifyMoiChange
  • Some issues with the NotifyMoiChange path parameter
    • ... how to set it ... how to map to yang path? (Does it define yang path?)
  • Currently message is not used in SDNR ... todo
  • ref 3GPP TS 28.532  SA5 Rel16 - link https://www.3gpp.org/ftp/Specs/archive/28_series/28.532/28532-g81.zip 
• Added necessary schema (from zip above) to VES Collector as external schema (& updated schema config file with topic etc)
  
  • DMaaP Topic: unauthenticated.SEC_3GPP_PROVISIONING_OUTPUT
• Code in repo (WIP) - Link in Gerrit:
  • https://gerrit.onap.org/r/c/ccsdk/features/+/124226
    https://gerrit.onap.org/r/c/ccsdk/features/+/124227
    https://gerrit.onap.org/r/c/ccsdk/features/+/124138
• Martin Skorupski N.K. Shankaranarayanan Alex Stancu - will work on how to create the CM notify message in simulators etc.
• Related work using CM notify messages happening for updates to ONAP CPS:
  • Can be reused after parsed by SDNR as above 
  • https://wiki.onap.org/display/DW/SDN-R+Feature+for+adding+cm-handle
    • Not handling CM-Notify in the case above ... but CM-Notify will be looked at too.
  • N.K. Shankaranarayanan will bring relevant people together to join up?
  • Pawel Slowikowski Where does CPS get message? From SDNR, or from DMaaP? Is message reparsed?
    • Martin Skorupski   Device → VES → Collector → DMaaP → SDNR (or elsewhere) → CPS ???
      • SDNR (or elsewhere) will add identifiers (CMHandle ??) of where the message came from for CPS
