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 sequence flows and test cases are for an OOF enhancement proposal for Casablanca in the context of a 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 A) - From SO (new cell addition), only PCI recommendation, no Controller action
(Flow B) - From SDNC(R) (RAN config change), includes Controller action
(Flow C) - From DCAE (alarm/fault), includes Controller action and DCAE Collector

Flow A: PCI Optimization for trigger from SO (new cell addition)
