Overview
SON-Handler application acts upon reception of two types of events (Measurement and Fault events) and Neighbor list change notification from SDNR.
Fault events are sent whenever collisions/confusions found by the Ran-simulator due to pci changes and at the same time SDNR notification is also sent whenever there is change in pci value.Measurement events are periodically sent from Ran-simulator which gives the KPI information.
SON-Handler processes the events and calls OOF for global optimization. Then it determines the actions based on OOF response and writes to unauthenticated.DCAE_CL_OUTPUT for policy to take necessary actions.

Deployment Prerequisite/dependencies
SON-Handler service requires DMAAP and Policy components to be functional.
SON-hadler service requires the following dmaap topics to be present in the running DMAAP instance :
1.PCI-NOTIF-TOPIC-NGHBR-LIST-CHANGE-INFO
2.unauthenticated.SEC_FAULT_OUTPUT
3.unauthenticated.SEC_MEASUREMENT_OUTPUT
4.DCAE_CL_RSP
Policy model required for SON-handler service should be created and pushed to policy component.
Deployment Steps
- Copy sonhms-blueprint and inputs file to /blueprints directory in DCAE bootstrap POD
- Log-in to the DCAE bootstrap POD's main container
validate and deploy blueprint
Code Block language bash firstline 1 title Deploy component cfy install -b sonhms -d sonhms -i <inputsFilePath> <blueprintFilePath>undeploy
Code Block language bash firstline 1 title Undeploy component cfy uninstall sonhms
delete blueprint
Code Block language bash firstline 1 title Delete blueprint cfy blueprints delete sonhms
Validation
The status of service can be checked after the deployment using command "kubectl get pods --namespace onap |grep son"
