Problems solved by technology

[0008] In the interference measurement, analysis and modeling scheme, the first implementation method mainly relies on the measurement and statistical capabilities of the base station, and the acquisition of test data mainly depends on the network conditions within the set time period, and the reliability of the test results is low.
For example, when a certain regional network is temporarily under low load conditions, because the measurement data under high load network conditions cannot be obtained, it is impossible to evaluate the anti-interference performance of the network under high load conditions, so that the problem can only be found after the event, but cannot be done. to a proactive grasp of the system
However, the computer simulation analysis model established by the second implementation method uses a fixed path loss model and user distribution model, and the simulated interference environment is relatively simple, which cannot reflect the actual path loss and user distribution.
[0009] In the construction scheme of the interference environment, since only a certain number of users are mechanically loaded to construct the interference environment, it cannot reflect the actual interference and user distribution
[0010] Based on the above problems, the communication system interference test based on the existing technology cannot reflect the interference and user distribution in the actual situation, resulting in a large deviation between the test results and the actual network interference, thereby reducing the interference to the communication system test accuracy
