R5 El Alto Carry-over
Two Jira carry over items in SDN-C
R6 Frankfurt development
1. Functional enhancements:
Onboard RAN-Simulator as an official ONAP component (e.g., as part of Demo VNFs repo or Integration test repo),
Contribute to ConfigDB (or RuntimeDB) enhancements for SON use case (including any impacts in SON-Handler MS, OOF and SDN-C) => this scope currently only includes yang model driven automatic Config DB schema and API generation.
2. Alignment with O-RAN
Netconf config (O1-CM interface), yang model sourced from OIM => this is now de-scoped as we don't have yang models from O-RAN as of Jan 20th, 2020
VES messages for config-update notifications also => the scope only includes reception of DMaaP message by SDN-R that would be triggered when RAN sends a VES config-update message. The real VES message sending as well as reception by VES Collector in DCAE is de-scoped as we don't yet have the VES message definition from O-RAN.
3. Control Loop Co-ordination (CLC)
Demonstrate CLC with PCI and ANR CLs
4. Optimization feature enhancements (stretch goal)
Adaptive SON functionality

Test cases
No. | Description | Involved components | Status |
1 | Successful reception and handling of DMaaP message by SDN-R with CM notification (simulated from RAN). | DMaaP, SDN-R | NOT YET TESTED |
2 | Successful update of ConfigDB with CM notification updates by SDN-R (upon reception of CM notification over DMaaP from RAN) | SDN-R, DMaaP | NOT YET TESTED |
3 | Control Loop co-ordination – denial of 2nd control loop trigger (by Policy) received from SON-Handler MS when first control loop is active | SON-Handler MS, OOF, Policy, SDN-R, RAN-Sim | NOT YET TESTED |
4 | Control Loop co-ordination – re-submitting of 2nd control loop trigger (by SON-Handler MS) and initiating appropriate actions | SON-Handler MS, Policy, SDN-R, RAN-Sim | NOT YET TESTED |
5 | Keep track of PCI updates being successfully implemented in the RAN and update DB accordingly for future optimizations. | SON-Handler MS, Policy, SDN-R, RAN-Sim | NOT YET TESTED |
6 | Trigger OOF for adaptive SON with FixedPCI cell list (by SON-Handler MS) when previous PCI updates are not implemented in the RAN | OOF, SON-Handler MS | NOT YET TESTED |
