    • ongoing - see last weeks meeting minutes
    • LNF project onboarding
  • Non-RT-RIC:
    • focus O-RAN-SC to use the ONAP Adapter → Doc
    • testing an demos in preparation
    • Licensing issues becomes now also in issue
  • SIM:
    • sim/o1-interface: updated code in gerrit
      • working on LF Jenkins jobs for the new code
    • final preparations for Cherry (INT specific tasks)
  • OAM:
    • ONAP SDN-R code adopted for ODL Aluminium → module tests ongoing
      • RestConf to NetConf subtree filtering

Use Cases

Please see page #2 for details: 
5G Use Cases in R7 Guilin. - 

very first view - to be discussed further:

  1. BULK PM –PM control
    • 100% aligned with O-RAN interface specification; use case was demonstrated several times
      proposal: Check updates of 3GPP pm xml file format and updates of VES messages
  2. OOF -SON PCI (5G)
  3. 5G SERVICE MODELING & DEFINITION (5G)
  4. CONFIGURATION PERSISTENCE SERVICE (CPS)
    • use VES 7.2 - reference will be in O-RAN specs.
    • use 3GPP NRM - see https://forge.3gpp.org/rep/sa5/MnS/
    • open: is the abstraction by 3GPP and O-RAN sufficient for all the targeted use case - how do µServices, rApps make use of C&PS, if C&PS is device model driven and not service model driven?
      • C&PS is model-driven based on the current use case
      • Abstraction later... impact on point #3
    • Idea: Contribution of consumer view
  5. xNF LICENSING MANAGEMENT
    • not subject of O-RAN (yet)
    • proposal: defer or contribute terms, definitions, specifications to O-RAN
  6. ONAP/3GPP & ORAN Alignment
    • O-RAN O1 data models are augmenting 3GPP data models
    • A1, R1, O2 data models are subject of O-RAN only
  7. ONAP/ORAN Alignment -A1 adapter
  8. 5G NRM (CM)
  9. E2E NETWORK SLICING (5G Use Case)
    • Network Slicing is not part of 3GPP NRM so far
      proposal: waiting for 3GPP and O-RAN specifications  - V17 draft is available


Feedback from John Keeney (Ericsson EST): Request for chat for such use cases in Honolulu.

Application Package Structure

  • TOSCA 

Info from Michela Bevilacqua

  • ONAP enhanced TOSCA 
  • API schema definition for YANG and VES

On the agenda for next week - thanks!!! (wink)

Postman scripts to interface with the SMO and in turn test O1 interface between the SMO and different parts of O-RAN instances of O-CU, O-DU, O-RU and RIC using these models. 

  • yang modules
  • framework for test and validate CM 

share content in in SMO gerrit and create wiki linking to the same source

  • Working on a framework for vendors for OAM/YANG tests
  • O-RAN-SC to host the framework
  • Postman and vsCode as RestClients
  • Alex about to setup a SIM in OSC lab - involve Rittwik in a O-RAN private lab
  • OpenFronthaul
  • 3GPP models are considered.

Feedback from Rittwik

  • SMO in T-Labs
  • how to run Netopeer server - req to Felix (O-RAN-SC INT PTL)
  • Alex asked for VMs 

Init script (Postman) for O-RAN OAM FH M-Plane (o-ran-interface.yang augmenting ) interface demoed

RFC8040 (RestConf by IETF) support supported by ODL

O-RAN Component deployment

The question is: How to deploy the red colored CNFs/VNFs of the O-RAN-Architecture?

  • CNF for O-RAN-components 
    • model of CNF - how to be configured, how many components, blueprints
    • CDS model needs to be created
    • Network-service based on several CNFs
      • CNF types
        • Near-RT-RIC
        • O-CU-UP
        • O-CU-CP
        • O-DU

For detailed discussion the following page was created:


Package

  • for Network Functions (priority)
  • for Network Service (second step)

CNFs or VNFs

  • both should be considered 
    • let's start with CNFs first
    • VNF is considered as additional option


  • no CNFs and VNFs combined in a single package
    • maybe not for rApps → 
    • VNF should take care about internal CNFs
