General

The O-RAN Non-RT RIC Policy Management Service\ \ provides a REST API for managemecnt of A1 policies.
The main tasks of the\ \ service are:

APIs\ \ provided or defined by the service

A1 Policy Management

This\ \ is an API for management of A1 Policies.

Management\ \ of configuration

API for updating and retrieval of the component configuration.\ \ Note that there other ways to maintain the configuration.

Service callbacks

These\ \ are endpoints that are invoked by this service. The callbacks are registered\ \ in this service at service registration.

NearRT-RIC Repository

This\ \ is an API that provides support for looking up a NearRT-RIC. Each A1 policy\ \ is targeted for one Near-RT RIC.

Health Check

API used for supervision\ \ of the PMS component.

Service Registry and Supervision

API used\ \ for registering services that uses PMS. Each A1 policy is optionally owned by\ \ a service. PMS can supervise each registered service by a heart-beat supervision\ \ and will automatically remove policies for unavailable services. Note that a\ \ service does not need to be registered in order to create A1 Policies. This\ \ is a feature that is optional to use.

Authorization API

API used\ \ for access control of A1 Policy access. If configured, an external authorization\ \ provider is requested to grant access to the A1 Policy type.

Spring Boot\ \ Actuator

Provides generic functions used to monitor and manage the Spring\ \ web application.
