ZTE Corporation, an international provider of telecoms, enterprise and consumer technology solutions for the mobile internet, reports that the Guangdong branch of China Unicom and ZTE have made the world’s first 5G call by means of ZTE’s 5G prototype smartphone in Shenzhen 5G field trial. The test also completed the verification of diverse services, such as Wechat group voice call, online video and web browsing.
According to ZTE, this means that the Shenzhen sector of China Unicom is the world’s first commercial test field to have made a call in NSA mode and in compliance with the 3GPP Rel-15. Known as “the City of Innovation”, Shenzhen is one of the first 5G pilot cities for China Unicom. Shenzhen is fully verifying the 5G network equipment’s networking capabilities, special services, roaming and interconnection, and the inheritance of existing services in phases, thereby laying a solid foundation for the 5G whole network commercial construction.
The test adopted ZTE’s 5G end-to-end solution, including radio access network, core network, transport network and intelligent device, achieving the connection with ZTE’s 5G prototype smartphone in the field environment. Meanwhile, the test has verified several 5G key technologies such as Massive MIMO, 5G NR, NSA dual connectivity, FlexE transport technology and 5G Common Core.
The first call of ZTE’s 5G prototype smartphone in the NSA mode conducted in ChinaUnicom Shenzhen field was successful. ZTE’s 5G solution has passed the end-to-end test in the three months after the release of the 3GPP Rel-15. It showcases ZTE’s strong competency in 5G R&D and commercialisation, demonstrating ZTE’s role as a reliable partner to global 5G operators and a key player in the 5G industry.
