Introduction

• 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 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, SDN-C 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
