Case Study: NTT DOCOMO achieves faster, scalable firmware updates and improved customer experience with Limelight Networks' Orchestrate Platform

NTT Docomo Needed to Reduce the Burden of Delivering Smartphone Firmware Updates and Improve Customer Service

NTT DOCOMO, Japan’s leading mobile operator, faced growing strain on its internal Firmware Over-The-Air (FOTA) delivery system as its customer base and update file sizes expanded. The company needed to reduce the operational burden of distributing Android firmware updates, improve delivery times, and scale capacity without continuously adding servers and network upgrades.

NTT DOCOMO migrated to Limelight Networks’ Orchestrate Platform CDN after vendor testing, gaining high cache hit rates, scalability, zero-rated traffic capabilities, and dedicated support. The move sped up update delivery, handled unpredictable traffic spikes and larger files more efficiently, and was implemented faster than planned—improving customer experience and reducing operational overhead.
