Case Study: NTT DOCOMO achieves 10x faster mobile billings and lower maintenance costs with Oracle Exadata

NTT Docomo - Customer Case Study

NTT Docomo, Japan’s largest mobile service provider, needed a high-performance, reliable, and cost-effective billing platform to handle rapid growth, improve service quality, and support its “+d” initiative. To meet these demands, the company turned to Oracle Exadata and related Oracle services for its MoBills mobile billing system.

Oracle Exadata helped NTT Docomo consolidate 350 legacy database servers and storage systems onto 30 Oracle Exadata Database Machines, cutting maintenance costs in half and installation costs by 25%. The new platform processed mobile billings more than 10x faster, enabled real-time billing for a billion calls a day, improved availability and service responsiveness, and accelerated new service launches and application development.
