  • Will demo RAN PM function soon. (Maybe part of it next week)

• Otherwise Work ongoing - as per last week:

  • Making good progress on rApp manager.  (Hope to demo in a couple of weeks)

  • 3PP dependency updates & addressing vulnerability

  • OpenAPI-first in A1-PMS & ICS

    • Change from code→openapi→docs to openapi → code-stubs & docs

    • To better align with R1 specs as they mature

    • To improve expressivity of docs etc.

  • Issue with test framework

    • Underscore in URI hostnames - introduced by docker-compose (v1)

  • Some changes in A1-Mediator in near-RT-RIC plt in H-Release.

    • Further investigation needed re effects on A1-PMS/ICS & A1-SIM

    • Will return to this in a week or 2.

SIM (Alex Stancu)

• I-Release planning
• Focusing on PM Streaming - likely to be the main feature for I-Release

PM Data Streaming (Martin Skorupski & All)

• PM Streaming
• O1 spec seems to indicate 3GPP approach => websocket & (ASN1 or Protobuf)
  
  • .. but not much detail on either ASN1 or protobuf schema
  • Should be possible to use protobuf based on 3GPP XML XSD
    • ... looks possible (easy?) to map xml→protobuf based on XSD
      • Hopefully next week show a sample protobuf schema based on XSD.
    • ASN1 version seems tricky & maybe incomplete? ... So prefer Protobuf version.
  • Sample flow at https://wiki.o-ran-sc.org/download/attachments/82706888/o-ran-sc-i-pm-streaming-sequence.png?version=5&modificationDate=1692085150222&api=v2 from PM Streaming page.
    • Discussed a few simplifications, e.g. maybe REST for rApp→OAM for job setup, decouple DME-subscription & O1-PMJobCoordination initially, reuse existing file-based RAN PM fucntions for data subscriptions to rApp, etc.
• More next week.

Follow up from last week: CPS & SDNR (Martin Skorupski)

• CPS & SDNR: (Vishal Varvate, Martin Skorupski) in ONAP SON Usecase
