Guangzhou Branch of China Mobile, ZTE and Ericsson have taken the lead in making a VoLTE voice and video call between 5G and 4G smartphones.

Unlike the previous tests completed via 5G smartphones and transported by trial networks, this call utilizes NSA 5G networks provided by different vendors as well as the existing 4G network. This test adopts ZTE’s 5G and 4G smartphones to make a VoLTE voice and video call while achieving the download with a stable data stream, meeting the commercial requirements in all aspects. This test makes a call between 5G and 4G smartphones while using internet access.

In March, Guangdong Branch of China Mobile and ZTE completed the voice and video call verification between two 5G smartphones in Zhujiang New Town of Guangzhou.
