The process of obtaining the interference data includes: taking the mobile station in the transmission area and the mobile station in the reception area as the two endpoints of the major axis and the direction influence value of the test data group corresponding to the test sub-data as the minor axis to make an elliptical area, and marking the number of signal interferers in the elliptical area as the interference data.

[0039] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figure 1 shown, a mobile communication performance test system based on data analysis includes a test environment simulation module. The test environment simulation module is communicatively connected to a directivity test module. The directivity test module is communicatively connected to a display terminal. The directivity test module is also communicatively connected to a performance monitoring module and a fading analysis module. Both the performance monitoring module and the fading analysis module are communicatively connected to an optimization evaluation module. The optimization evaluation module is communicatively connected to the display terminal.

[0041] Embodiment 1

[0042] As Figures 2 - 3 shown, the test environment simulation module is used to simulate a mobile communication performance test environment: divide the mobile communication performance test area into several test areas, set a mobile station in each test area, and then randomly generate several test data groups. The generation process of the test data groups includes: randomly select a test area as the sending area, then randomly select a test area as the receiving area, form a test sub-data by the mobile station in the sending area and the mobile station in the receiving area, then swap the sending area and the receiving area in the test sub-data and re-form a test sub-data, and form a test data group by two test sub-data; perform mobile communication tests according to the test data groups and send the mobile communication parameters to the directivity test module.

[0043] Exemplarily, as Figure 3As shown in the figure, when the mobile communication area is divided into seven test areas (A1 - A7), the corresponding workbenches B1 - B7 are assigned to them. When A1 and A3 are selected as the sending area and the receiving area respectively, the two test sub - data of the test data group are (B1, B3) and (B3, B1). It can be understood that when B1 is the mobile station in the sending area, when the mobile signal is transmitted and refracted through the antenna node, the degree of signal attenuation is from weak to strong (B3 is farther from the antenna node for signal transmission and refraction). And in the test sub - data corresponding to this test sub - data, that is, when B3 is the mobile station in the sending area, the degree of attenuation of the mobile signal is from strong to weak. Then, the numerical deviation degree of the two direction coefficients FX in the same test data group can reflect the influence degree of the antenna node distribution on the signal transceiver directivity in the mobile communication test area.

[0044] The directivity test module tests the signal transceiver directivity in the mobile communication test area after receiving the mobile communication parameters: The mobile communication parameters include the distortion degree SZ, the spectrum bandwidth PP, and the transmission duration CS of the signal received by the mobile station in the receiving area when the same signal is sent by the two test sub - data in the test data group; The direction coefficient FX of the test sub - data is obtained through the formula FX=(v1 * SZ + v2 * PP + v3 * CS) / 3, where v1, v2, and v3 are all proportionality coefficients, and v1 > v2 > v3 > 1;

[0045] Calculate the difference between the direction coefficients FX corresponding to the two test sub - data in the same test data group and take the absolute value to obtain the direction influence value of the test data group. Sum and average the direction influence values of all test data groups to obtain the direction influence coefficient of the mobile communication test area. Compare the direction influence coefficient with the preset direction influence threshold: If the direction influence coefficient is less than the direction influence threshold, it is determined that the signal transceiver directivity in the mobile communication test area meets the requirements, and the mobile communication parameters are sent to the performance test module and the fading analysis module; If the direction influence coefficient is greater than or equal to the direction influence threshold, it is determined that the signal transceiver directivity in the mobile communication test area does not meet the requirements, generate an antenna adjustment signal and send the antenna adjustment signal to the display terminal; After simulating the mobile communication test environment, several test data groups are obtained. By swapping the sending end and the receiving end in the test data group, two test sub - data are obtained, so as to analyze the deviation degree of the direction coefficients corresponding to the two test sub - data in the same test data group, and determine the overall influence of different antenna node distributions on mobile signal transmission.

[0046] Embodiment 2

[0047] As Figure 4As shown, the performance monitoring module is used to monitor and analyze the mobile communication performance of the test area: obtain the direction coefficient FX, distance data JL, and interference data GR corresponding to each test sub-data. The distance data JL is the straight-line distance value between the mobile station in the signal transmission area and the mobile station in the receiving area during the test process. The process of obtaining the interference data GR includes: taking the mobile station in the transmission area and the mobile station in the receiving area as the two endpoints of the major axis, and the direction influence value of the test data group corresponding to the test sub-data as the minor axis to make an elliptical area, and marking the number of signal interference objects in the elliptical area as the interference data. The signal interference objects include residential buildings, factories, hospitals, shopping malls, and office buildings; the performance coefficient XN of the test sub-data is obtained through the formula XN = FX / (t1 × JL + t2 × GR), where t1 and t2 are both proportionality coefficients, and t1 > t2 > 1; sum and average the performance coefficients XN corresponding to the test sub-data in all test data groups to obtain the performance value of the mobile communication performance test area, and feedback the mobile signal transmission status from the signal reception angle through the performance value; send the performance value to the optimization evaluation module.

[0048] In an actual mobile communication system, mobile stations often operate in urban building complexes or other complex geographical environments, and the speed and direction of movement are arbitrary. After the transmitted signal passes through propagation paths such as reflection, diffraction, and scattering, the signal received at the receiving end is often the superposition of multiple signals with different amplitudes and phases, causing the amplitude of the received signal to randomly fluctuate and change, forming multipath fading.

[0049] The fading analysis module is used to analyze the signal transmission fading state in the mobile communication performance test area: randomly select several test sub-data and label them as analysis sub-data. During the mobile communication test of the analysis sub-data, set several analysis time points, and obtain the propagation delay values, phase values, and amplitude values of all signal components in different transmission paths at the analysis time points during the mobile communication test of the analysis sub-data. Calculate the variance of the propagation delay values of all transmission paths at the same analysis time point to obtain the propagation deviation value, calculate the variance of the phase values of all transmission paths at the same analysis time point to obtain the phase deviation value, calculate the variance of the amplitude values of all transmission paths at the same analysis time point to obtain the amplitude deviation value, label the sum of the propagation deviation value, phase deviation value, and amplitude deviation value at the same analysis time point as the deviation performance value at the analysis time point, sum and average the deviation performance values at all analysis time points in all analysis sub-data to obtain the fading coefficient of the mobile communication performance test area. The fading coefficient represents the transmission performance difference of different signal components in different transmission paths when the mobile signal is transmitted. Therefore, when the optimization evaluation module synchronously compares the performance value with the fading coefficient, it can target the performance influencing factors of the mobile communication network for targeted optimization, so that the mobile communication performance can be effectively improved; send the fading coefficient to the optimization evaluation module.

[0050] The optimization evaluation module is used to conduct communication optimization evaluation and analysis on the mobile communication performance test area: compare the performance value and the fading coefficient with the preset performance value threshold and fading threshold respectively: if the performance value is less than the performance value threshold and the fading coefficient is less than the fading threshold, it is determined that the mobile communication state in the mobile communication performance test area meets the requirements, generate a status qualified signal and send the status qualified signal to the display terminal; if the fading coefficient is greater than or equal to the fading threshold, it is determined that the signal transmission fading state in the mobile communication performance test area does not meet the requirements, generate a diversity optimization signal and send the diversity optimization signal to the display terminal; if the performance value is greater than or equal to the performance value threshold and the fading coefficient is less than the fading threshold, it is determined that the anti-interference performance in the mobile communication performance test area does not meet the requirements, generate an interference optimization signal and send the interference optimization signal to the display terminal.

[0051] A mobile communication performance testing system based on data analysis, when working, simulates the mobile communication performance testing environment: divides the mobile communication performance testing area into several testing areas, sets a mobile station in each testing area, then randomly generates several testing data groups, obtains mobile communication parameters through the testing data groups, performs numerical calculations on the mobile communication parameters to obtain a direction influence coefficient, determines whether the signal transceiver directivity of the mobile communication testing area meets the requirements through the direction influence coefficient, respectively conducts mobile communication performance monitoring analysis and signal transmission fading state analysis on the testing area and obtains a performance performance value and a fading coefficient, and determines the necessity and optimization direction of mobile communication performance optimization through the performance performance value and the fading coefficient.

The coefficients in the formula are set by those skilled in the art according to the actual situation; the magnitude of the coefficient is a specific value obtained by quantifying each parameter.
