Abstract: An intelligent Radio Access Network (RAN) optimization framework. For an E2 Node, optimization services are initiated for handling by a Near-Real Time RAN Intelligent Controller (RIC) (Near-RT RIC). The E2 Node compares the performance to a first predetermined threshold. In response to the performance being below the first predetermined threshold, the E2 Node takes over optimization of the E2 Node. Otherwise, the Near-RT RIC continues optimization. The E2 Node compares the performance of the E2 Node to a second predetermined threshold. In response to the performance being below the second predetermined threshold, the Near RT RIC resumes handling the optimization. Otherwise, the E2 Node continues to handle the optimization of the performance of the E2 Node. For an Open-RAN Radio Unit (O-RU) Node, the O-RU Node performs local optimization of time-critical functions and a Non-RT RIC is able to perform optimization of non-time critical functions.
