Nokia implemented its MantaRay SON self-organizing network solution within NTT DOCOMO’s multi-vendor 5G and Long Term Evolution (LTE) Radio Access Network (RAN) in Japan. This deployment represents the initial use in Japan of Nokia’s 5G base station technology integrated with DOCOMO's operational systems, aimed at increasing automation in network operations.

The collaboration sought to improve the operational workflow for 5G networks, addressing challenges posed by the vast infrastructure including thousands of base stations and millions of cells. Automating routine network functions intended to enhance service quality and operational cost-efficiency.

The MantaRay SON solution supports automation across planning, provisioning, and verification phases, enabling closed-loop management whereby system configurations change automatically in response to detected conditions without manual intervention. The integration focused on aligning various operational systems to maintain network performance and timely quality adjustments. Future updates are planned to expand support across multiple vendors and include capabilities such as MantaRay AutoPilot and Non Real-Time RAN Intelligent Controller (RIC) functions.

Mark Atkinson, Nokia’s Head of Radio Access Networks, said, “Nokia is proud to partner with NTT DOCOMO to bring cutting-edge AI-driven automation to Japan’s telecom industry. MantaRay SON represents a significant leap forward in managing the complexity of 5G networks, delivering superior efficiency and customer experience. Together, we are shaping the future of network operations.” Masafumi Masuda, General Manager of Radio Access Design Department at NTT DOCOMO, said, “Nokia’s highly automated MantaRay SON solution will help us deliver an enhanced customer experience by accelerating our quality improvement cycles. Its open interface capabilities will strengthen our O-RAN 5G commercial network, while its advanced AI features will reduce operational costs and further improve service quality. We are excited to continue this journey with Nokia, a trusted partner that has supported us every step of the way as we move toward more open networks.”

MantaRay SON functions as part of Nokia’s Service Management and Orchestration framework, utilizing Artificial Intelligence (AI) to optimize network operations. It contributes to DOCOMO’s objective of reaching Level 4 autonomous network capabilities by advancing automation within its infrastructure.
