title: A1 Policy management service
description:
General
The O-RAN Non-RT RIC Policy Management Service provides
a REST API for management of A1 policices.
The main tasks of the service
are:
- A1 Policy creation, modification and deletion.
- Monitoring
and maintaining consistency of the SMO view of A1 policies and the Near-RT RICs
- Maintaining
a view of supported Near-RT RIC policy types
- Supervision of using services
(R-APPs). When a service is unavailble, its policies are removed.
APIs
provided by the service
A1 Policy Management
This is an API for
management of A1 Policies.
- A1 Policy retrieval, creation, modification
and deletion.
- Retrieval of supported A1 Policy types for a Near-RT RIC
- Retrieval
of status for existing A1 policies
Management of configuration
API
for updating and retrieval of the component configuration. Note that there other
ways to maintain the configuration.
Callbacks
These are endpoints
that are invoked by this service. The callbacks are registerred 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 registerring services that uses PMS.
Each A1 policy is owned by a service. PMS can supervise each registerred service
and will automatically remove policies for unavailable services.
