In order to measure the transmission performance of real 5G SA communication system, this paper completed the integration and connection test of 5G SA system based on OAI platform and universal software radio peripheral USRP. OAI wireless technology platform is an open source communication platform for open LTE and NR systems. It is committed to the realization of open source 5G NR. This paper introduces how to build 5G NR SA system based on OAI platform in detail, including the structure and principle of 5G NR SA system and the code architecture of OAI platform. Describes the installation and configuration of the 5GC core network, base station gNB, and the user terminal UE. In addition, a variety of user access scenarios including computer terminals and commercial terminals are further tested and implemented. At the same time, the laboratory test results show that the established 5G NR SA communication system can achieve connectivity between UEs and gNB, and maintain a relatively stable connection.
