Problems solved by technology

[0005] It can be seen that the existing technology is mainly designed and simulated for the channel environment and performance test, the operation is complicated, the cost is high, and the basic function test and regression test are not considered comprehensively; the baseband simulation method is mainly to realize a single base station to UE simulation process

[0006] To sum up, the existing technology connects the base station and UE through an attenuator, which has many devices, complicated connection, insufficient manual adjustment accuracy, poor controllability, and low use efficiency; connecting the base station and UE wirelessly, due to the air interface environment The controllability is poor, and it is usually achieved by changing the position of the UE. For laboratory tests, the test efficiency is low; the existing technology uses baseband simulation, which cannot simulate the impact of the wireless environment on the entire system, and cannot simulate users. interference between wireless channels, and cannot simulate multi-user and multi-base station scenarios; for the simulation of complex connections and UE mobility characteristics, the ability is limited
