NTT DOCOMO, INC. and NEC Corporation have launched Japan’s first commercial 5G core network (5GC) on Amazon Web Services (AWS), marking a major step in hybrid cloud-based telecom infrastructure.
The 5GC, commercially launched on February 26, 2026, combines DOCOMO’s proprietary virtualization platform with AWS to create a hybrid cloud architecture. The system enables dynamic capacity scaling during traffic surges and is designed to enhance reliability, flexibility, and sustainability. Operational testing showed power consumption reductions of around 70% using AWS Graviton processors.
In a separate world-first milestone, DOCOMO and its group companies automated the entire 5GC design and construction process using Agentic AI integrated with GitOps on AWS. By leveraging Amazon Bedrock AgentCore and infrastructure-as-code methodologies, the companies reduced network construction time by approximately 80% compared to conventional approaches.
The initiative is being showcased at Mobile World Congress 2026 in Barcelona, highlighting AI-driven automation and cloud-native architecture as the next phase of telecom network evolution.
