Jakarata Release 



11/08 - SON Use Case Jakarata plan presented in Requirements Subcommittee on 11/08/20201 call

Jakarta release - functional requirements proposed list#5GOOFSONUseCase 



CCSDK-3532



Yashwanth clarified that he is working on one part of CCSDK-3532 - the DG in SDN-R which use the new yang model.
Created a separate JIRA CCSDK-3544: Modify SDN-R to use new yang models in netconf session with RAN-SimClosed as a task in CCSDK-3532

DCAEGEN2-2986
(PM VES formats)



Discussion focused on PM VES messages. Thanks to information from Martin and Alex.

There is very relevant work in O-RAN WG10. 

See https://oranalliance.atlassian.net/wiki/spaces/OAMWG/pages/2227307301/PM+Coordination+Team 

In particular, see the Excel table with a list of PM metrics relevant to O-RAN FCAPS

There is consensus in ONAP/OSC/O-RAN to use VES stndDefined domain.

We believe that this will be acceptable to 3GPP and O-RAN. stndDefined domain
requires a schema.

Note that the sample PM message uploaded in DCAEGEN2-2986: DCAE impacts for 5G OOF SON use case in Jakarta releaseClosed does not have a schema and is thus incomplete.

Note that OSC smo project is using VES measurement domain now but wants to move to stndDefined.

Lot of detail about PM metrics and schema have been added in comments in DCAEGEN2-2986: DCAE impacts for 5G OOF SON use case in Jakarta releaseClosed 

There are two approaches to provide a reference to the metrics to the systems processing the PM VES message:

1) Current OSC approach: VES message refers to schema and yang model which points to the measurements in the VES message

payload

2) Current ONAP approach: VES message assumes that a PM Dictionary is loaded  initially and this provides a reference for the

measurements in the VES payload. This is supported by the ONAP VES Collector.

In either case, there is more work needed to align with the PM metrics being defined in O-RAN WG10 (based on 3GPP).
