Design and Verification of 5G Light-Weight Platform Based on Software Defined Radio
The paper compared and analyzed four open-source platform implementation standards based on software defined radio(SDR).Based on the research and analysis of 5G system architecture and protocol system,an OAI platform that supports multiple air port protocols was selected to design a 5G system verification platform,including platform hardware architecture,access network,and core network design.The platform realized 5G base station gNB,terminal UE,core network elements.Corresponding tests were conducted on the built 5G system simulation verification platform,and the N1/N2/N3 interface was implemented to verify the feasibility of the platform.This provides effective means for achieving lightweight 5G core network and wireless network,prototype function verification,interface enclosure testing,emergency communication business testing,etc.It has reference significance for the design,acceptance,and operation and maintenance of railway 5G-R.
