R5 El Alto Carry-over
Two Jira carry over items in SDN-C
R6 Frankfurt development
(1) PCI ENHANCEMENTS
Enhancements of Neighbor relations.
Complete the loop, when a new cell is added A&AI update, SO W/F.
Assign a PCI for the new cell (not considered in R4).
When a nbr list is updated a collision/confusion can happen.
New Cell Additions, go through the entire life cycle; cell addition; nbr list update.
(2) NEW SON U/C -
Additional SON U/C.
(3) INTEGRATION WITH REAL SYSTEMS -
SDN-R integration with a real DU. Evolving model to align with ORAN
...
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
