New functions to support A1 Policies have been added to ONAP. The A1 Policy functions are Orchestration and Automation functions for non-real-time intelligent management of RAN (Radio Access Network) functions. The primary goal of the A1 Policy functions is to support non-real-time radio resource management, higher layer procedure optimization, policy optimization in RAN, and providing guidance, parameters, policies and AI/ML models to support the operation of Near-RealTime RIC (RAN Intelligent Controller) functions in the RAN to achieve higher-level non-real-time objectives. A1 Policy functions include service and policy management, RAN analytics and model-training for the Near-RealTime RICs. The A1 Policy functions project provides concepts, specifications, architecture and reference implementations as defined and described by the ONAP architecture.
The A1 Policy functions implementation will communicate with Near-RealTime RIC elements in the RAN via the A1 interface. Using the A1 interface, the A1 Policy functions will facilitate the provision of policies for individual UEs or groups of UEs; monitor and provide basic feedback on policy state from near-RealTime RICs; provide enrichment information as required by Near-RealTime RICs; and facilitate ML model training, distribution and inference in cooperation with the Near-RealTime RICs.
A1 Policy functions form part of a Non-Realtime RIC as defined by O-RAN Alliance. Non-Realtime RIC functions include service and policy management, RAN analytics, and model-training for the Near-RealTime RICs. The ONAP A1 Policy work provides concepts, specifications, architecture and reference implementations for A1 Policy support as defined and described in the O-RAN architecture.
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).
