Why Architecture Defines AI ROI

We build AI into the network fabric. This ensures your high-level AI intents instantly translate into immediate, deterministic, and autonomous network state changes.
Rakuten Mobile has proven this blueprint at scale in Japan, delivering the real-world efficiency and massive scalability.
Network Sovereignty
Broke vendor lock-in with open, programmable interfaces that keep control of the network roadmap in the operator’s hands.
Proven Efficiency
Achieved TM Forum Level 4 Autonomy, as demonstrated by 20% RAN energy savings on live commercial networks.
Intent-Driven Operations
Shifted from manual, step-by-step scripts to high-level intent-based management that simplified complex, multi-domain network orchestration.
Scalable Autonomy
Deployed AI agents that reason across the stack, enabling predictive maintenance and dynamic slicing at massive scale.

FAQs
How does Rakuten Symphony achieve TM Forum Level 4 Autonomy?
Rakuten Symphony achieved TM Forum Level 4 Autonomy by integrating AI/ML directly into an Open RAN architecture. This enables the network to perform predictive maintenance, dynamic slicing and real-time optimization without manual intervention, as proven by the 20% RAN energy savings on Rakuten Mobile’s live commercial network.
How does Rakuten AI for Telecom differ from general-purpose AI?
General-purpose AI lacks domain context. Rakuten AI for Telecom is built on Large Language Models (LLMs) purpose-trained on deep network operational data. This enables highly accurate natural language intent declarations and automated root-cause analysis tailored to telecom environments.
What is the role of the Rakuten RAN Intelligent Controller (RIC)?
The Rakuten RIC platform acts as the operating system for network optimization, hosting rApps and xApps aligned with O-RAN specifications. It drives the near-real-time optimization loops necessary to sustain Level 4 autonomous network operations.
Can Rakuten Symphony’s AI solutions work with existing vRAN software?
Yes. Our Open RAN software is designed for cross-compatibility, overlaying AI workloads onto existing vRAN software stacks to optimize spectrum and trigger predictive, automated power-saving modes without requiring a total rip-and-replace. 
Why is cloud-native architecture essential for AI in telecom?
Cloud-native design is the foundation of scalable autonomy. It strips away vendor lock-in via open, programmable interfaces, handing operators complete control over their network roadmap while providing the agile infrastructure required to run the Rakuten AI Workbench at scale.
