NTT DOCOMO this week launches commercial VoLTE service in Japan partnering with Qualcomm Technologies. The solution is based on the Qualcomm® Snapdragon™ 800 processor with a fully featured multimode integrated VoLTE modem and IMS software solution that supports SMS, HD voice, video telephony (VT), and single radio voice call continuity (SRVCC), which can be found in a wide variety of smartphone devices available on NTT DOCOMO's network.
Qualcomm in a statement said that this is the first commercial VoLTE launch in Japan and the solution is designed to provide mobile users an enhanced, consistent user experience across LTE and 3G networks with SRVCC. The VoLTE solution is also designed to adapt to radio conditions for superior mobility performance, lower power consumption and optimized call latency, incorporating robust inter-technology working with 2G, 3G and WLAN. It noted that the solution has been extensively tested across major infrastructure vendors and operator networks.
"We are pleased to work with NTT DOCOMO on the first large-scale commercial VoLTE launch, which is designed to provide their customers in Japan with faster, more consistent user experiences. From improved voice call quality to faster data access, users will recognize the many benefits provided by the Snapdragon 800 processor VoLTE solution."

"NTT DOCOMO has launched the leading edge voice and video service, allowing VoLTE service to be available commercially nationwide in Japan as of June. We have successfully worked with Qualcomm Technologies in LTE technology for many years, which is why we chose to work with them for VoLTE technology as well. With this comprehensive, stable and extensively tested chipset with IMS software solution, we are able to provide leading edge VoLTE services on mobile phones from several manufacturers to our customers."
