DESCRIPTION

The O-RAN Alliance defines a new management interface "A1" for Radio Access Network (RAN) Management. This interface interconnects a new logical "Non-RealTime RAN Intelligent Controller (Non-RT-RIC)" function in the Service Management & Orchestration (SMO) layer with a new logical "Near-RealTime RAN Intelligent Controller (near-RT-RIC)" function in the RAN. This new A1 interface allows the Non-RT-RIC to provide Policy Guidance to the RAN (near-RT-RIC) to steer its operation. These policies are defined by the O-RAN Alliance as "A1 Policies". The specifications for the A1 Interface, including A1 Policy support, can be found on the O-RAN Alliance Specifications portal

...

As shown in the Component Architecture diagram below, the A1 Policy functions exist within the ONAP eco-system, leveraging existing infrastructure to support non-real-time control of the RAN (Radio Access Network).
