- ONAP Optimization Framework (OOF) provides a policy-driven and model-driven framework for creating optimization applications for a broad range of use cases
- For Casablanca, OOF enhancements include formulation and solving of optimization problems
- Following test cases are for an OOF Proof of Concept (POC) for Casablanca for Physical Cell ID (PCI) Optimization
- PCI Optimization is a well-understood problem
- The reading/writing of the Physical Cell ID (PCI) configuration parameter has been included in SDNC(R) POC - Objective of the POC is to demonstrate disaggregation of the PCI SON functionality, and the data flows needed to implement this in ONAP using OOF
- We envision a new PCI-Handler Microservice to facilitate the data flow and trigger mechanism
- The focus of the POC is on data flow and interfaces, and the role of OOF, PCI-Handler-MS, SDNC(R) Controller and Policy etc
- Objective is to incorporate an algorithm in ONAP using OOF, not to develop an algorithm
- The POC will help to develop details of ONAP interfaces and flows needed:
(a) to get the required network data to OOF for optimization,
(b) determine the recommended reconfiguration, and
(c) execute it using the Controller
Sequence Flows for OOF based PCI Optimization based on 3 different triggers:
(Flow 1) - From SO (new cell addition),
(Flow 2) - From SDNC(R) (RAN config change)
(Flow 3) - From DCAE (fault)
