Abstract: Since 2020,most of global main telecommunication operators have turned to 5G standalone architecture, and roll out the the commercial deployment of 5G standalone architecture. In the meantime,,3GPP R16 standard which supports all 5G service scenarios was frozen. The 5G Core network needs to be upgraded and make a evolution again soon. In line with the 3GPP standard schedule and product roadmap, 3GPP R17 and R18 standard version will miss the peak period of 5G SA construction, so 3GPP R16 maybe the most nominated commerical standard version in the next 3~5 years. As a result, it is very essential to make a systematic study about 3GPP R16, especially focusing on function architecture, application scenarios and impact on network.
