DOCOMO and NEC Launch Japan’s First Commercial 5G Core on AWS, Built with World’s First AI-automated Network Construction Technology

NTT DOCOMO, INC. and NEC Corporation today announced the launch of Japan’s first commercial 5G core network (5GC) on Amazon Web Services (AWS) on February 26.¹ Advanced architecture, constructed using Agentic AI,² enables the network to flexibly and rapidly expand capacity, such as dynamically expanding its capacity in response to sudden traffic surges, for dramatically improved reliability, flexibility and sustainability.

In a separate world-first achievement,³ DOCOMO and NTT DOCOMO BUSINESS, Inc. in collaboration with NTT DOCOMO SOLUTIONS, Inc. have also successfully automated 5GC design and construction on AWS. To do this, they leveraged Agentic AI—a combination of AI and GitOps⁴ in a hybrid cloud environment. This innovative approach prevents human error and reduces construction time by approximately 80% compared to conventional methods.
