Use case overview and impacted components are described in the 5G OOF PCI optimization main wiki page.

1. Architecture

This The architecture below depicts a standalone PCI micro-service. When this is moved to DCAE, it may undergo some adaptations, for e.g., the interfaces have to be adapted appropriately.the SON-Handler MS as a part of DCAE. Only the relevant interactions and components are shown.

1.1. Core Logic

...

This is a PostgreSQL DB, and is intended to persist information such as the following:

• PCI-Handler MS Config information (e.g., thresholds, timer values, OOF algorithm name, etc.)
• Pre-processing results and other related information (e.g., neighbor list)
• Buffered notifications (i.e., notifications not yet processed at all)
• State information
• Association between pnf-name and CellId

1.3. DMaaP Client

This is responsible for registering with the DMaaP client for the DMaaP notifications from SDN-R, and to Policy.

2. Core Logic components and Pre-processing algorithm
