    and maintaining consistency of the SMO view of A1 policies and the Near-RT RICs</li><li>Maintaining
    a view of supported Near-RT RIC policy types</li><li>Supervision of using services
    (R-APPs). When a service is unavailble, its policies are removed.</li></ul><h2>APIs
    provided by the service</h2><h3>A1 Policy Management</h3><p>This is an API for

    ways to maintain the configuration.</p><h3>Callbacks</h3><p>These are endpoints
    that are invoked by this service. The callbacks are registerred in this service
    at service registration.</p><h3>NearRT-RIC Repository</h3><p>This is an API that
    provides support for looking up a NearRT-RIC. Each A1 policy is targeted for one
    Near-RT RIC.</p><h3>Health Check</h3><p>API used for supervision of the PMS component.</p><h3>Service
