China Mobile, Nokia work on RAN automation - Mobile World Live 22 JAN 2021 China Mobile partnered with Nokia to conduct two trials using AI-powered RANs to forecast bandwidth requirements and detect anomalies, with the operator planning to automate its networks to reduce operating costs. In a trial in Shanghai, a RAN intelligent controller (RIC) was deployed in the edge cloud using Nokia’s AirFrame Open Edge server platform, which the vendor said enables “increased network optimisation capabilities through policy-guided, closed-loop automation”. Real-time traffic prediction accuracy exceeded 90 per cent on the operator’s live 5G network. Nokia said its RIC acts as a gateway to AI and machine learning (ML) technologies, enabling a range of real-time, data-driven network enhancements.
