REAL-TIME RAN INTELLIGENT CONTROLLER ARCHITECTURE

Abstract

An Open Radio Access Network (O-RAN) may include an O-RAN Centralized Unit (O-CU), at least one O-RAN Distributed Unit (O-DU), at least O-RAN Radio Unit (O-RU), and a Real-Time (RT) RAN Intelligent Controller (RIC) coupled to the at least O-DU and configured to host at least one application for controlling the at least one O- DU over a real-time control loop with a latency of less than 10 ms. The O-RAN wireless system may include a Non-RT (Non-RT) RIC configured to manage resources and events having a latency of 1 second or greater, and may include a Near-RT RIC configured to manage resources and events having a latency of 10 ms to 1 second. In addition, O-RAN may include a Service Management and Orchestrator (SMO) platform, where the RT RIC is connected to at least one of the SMO, the Non-RT RIC, the Near-RT RIC, RAN network elements and the O-RU.
