In order to solve the problem of UDM non-concurrent architecture design in free5GC,when uRLLC and eMBB are under heavy load,the time delay of UDM architecture is very large,this paper presents an improved design of UDM concurrent architecture based on open source free5GC,which can improve the concurrent processing capability of UDM,reduce the latency and improve the overall performance of the Core network,enhanced business processing capabilities such as uRLLC and eMBB.Simulation tests using open source free5GC show that under uRLLC,eMBB business type,and 2～3 business concurrent requests,the UDM concurrent architecture achieves 26.6%～49.2%time performance improvements compared with the non-concurrent architecture in the local virtual machine environment,there were 44.19%～63.3%time performance improvements in the CS Lab server environment.
