[CNMO News] Recently, some places in China will shut down the 5G base stations of the NSA's non-independent networking. The fact that only the SA independent networking 5G base stations will be retained has attracted the attention of many people. It can be seen that SA is the general direction of future development. Recently, Shandong Unicom and ZTE have completed 5G voice performance verification under SA networks in Linyi and Zhangqiu. This is the industry's first voice verification under the 5G co-construction and sharing and core network networking architecture of different manufacturers. The verification results show that 5G VoNR carries voice, which enables faster access and clearer calls.

After 5G SA networking is introduced into 5GC, it can achieve true low latency and high reliability, achieve a qualitative leap in 5G service experience, and meet the application needs of vertical industries. This commercial performance verification focused on the co-construction and sharing of 3.5GHz and 2.1GHz wireless networks, combined with the scenario of ZTE and the interconnection of core networks of different manufacturers, and verified the compatibility of the terminals by using mainstream 5G terminals on the market.

This test confirmed the interconnection and interoperability of VoNR in different scenarios and channel quality, and output the VoNR MOS value, network coverage and channel The fitting relationship of quality points out the direction for SA network coverage and optimization; establishes parameter standards for improving voice experience-related strategies, and completes the calibration of co-construction shared parameters.
