Nokia Siemens Networks to enable combined CDMA and LTE service in Japan

摘要

Nokia Siemens Networks is implementing its Circuit Switched Fallback (CSFB) technology to enable CDMA and LTE technologies to work together in KDDI's network in Japan. The deployment will allow KDDI to use its existing CDMA network to continue delivering high-quality voice services while maximizing the efficiency of its newly deployed LTE network.
