Kohn release reqs

Discussed reqs in following table. Will create JIRA as needed after discussion converges. Need to determine feasibility of work for SON-Handler MS and Policy.

A1 - based action

3/30 Good discussion on including A1-based action. Vishal Varvate is interested in contributing. He will work with John Keeney .
We discussed following plan:

  1. Implement A1 instance in SDN-R. Leverage past work in A1, including work for Slicing use case, and OSC.
  2. A1-policy trigger will be based on Control Loop msg sent from SON-Handler MS via Policy over DMaaP.
  3. RAN-Sim needs enhancement to have xApp abstraction to receive A1 message and update CU/DU state and send VES msg. If A1 policy
    message is about ANR/HO state, it can trigger xApp to make change to CU property. This chain replaces a direct O1 action for current ANR action.
  4. RAN-Sim update can leverage work for Slicing. The target for RAN-SIm work is to align with OSC and also plan to move to netopeer due to Honeycomb being archived.
    Possible approach is to add a netopeer-based server for near-rt-roc and xApp abstraction. Implementation of E2 to CU/DU can be abstracted. Details TBD.

4/19 Vishal needs info on A1 policy schema for ANR use case. Discussed details. Shankar to follow up.

4/26: Discussed control loop message formats for PCI and ANR and ANR policy schema. They are using same Policy name but different Control-Loop name and

different Action. See sample messages in file. Changes to ANR message format and control loop policy has impact on SON-Handler MS and Policy.

3/30 

Vishal presented slides below. We had a good discussion. Option 2 gives a little more flexibility for future use. John said they are willing to help with the A1 termination.
Netconf option instead of Websocket to RAN-Sim controller will need some integration work in RAN-Sim controller. Vishal will work with Niranjana on that.
Also sent a request to present in the ONAP/OSC Harmonization call today 3/30.

4/19 

Discussed change in terminology to avoid confusion. We are not implementing Near-RT RIC and xApp using OSC near-rt-ric.

Decision to change terminology to better capture the nature of the RAN-Sim enhancement.

Plan is to implement

  • A1-Termination
  • RAN App. (The App function is an abstraction which works with RAN-Sim, and does not implement E2 like an xApp on near-rt-ric )
