Agile 5G Networks: Advance Traffic Steering xAPP for Interference Mitigation

The Open Radio Access Network (O-RAN) signifies a substantial advancement in the telecommunications industry, with xAPPs and the RIC platform forming the core of its intelligence. By harnessing the agility of 5G and the capabilities of O-RAN, we can deploy intelligent applications, particularly for resilience and interference mitigation. We conduct a comprehensive analysis of the most prevalent xAPP service model in O-RAN, namely traffic steering, discovering its data flow and intelligent components. We identify challenges, propose solutions, and validate their effectiveness using O-RAN’s data and a system-level simulation. The results demonstrate significant enhancements in the accuracy and latency of the intelligence model, along with an 8.9% increase in throughput in the simulation.
