Under the condition that the mobile communication network signal corresponding to the area A4 is turned off, the area B3 is an overlapping area of the area A2 and the area A3, the wireless network routers 2011 corresponding to the area A2 and the area A3 are controlled to be turned on to output wireless network signals, the wireless network routers 2011 corresponding to the area A1 are controlled to turn off wireless network signal output, namely, the network state of the device to be tested in the area B3 can be simulated, and then the weak network test of the device to be tested in the area B3 can be realized.

TABLE 1
It should be noted that table 1 above only shows the case where the network signals of each area are enumerated in the presence and absence of two states, and there are 512 signal strength states in the process from the presence to the absence of the network signal of each area under the control of the digital rf power attenuator 223 responding to the control system 100, which is not listed here.
Fig. 9 is a schematic diagram for simulating the moving path of the device under test and the change of the network signal, as shown in fig. 9, in a single signal area (e.g., a1 area), when the signal strength of the device under test is the greatest, it indicates that the device under test X is located at the center of the area, and when the control system 100 controls the network signal corresponding to the area to gradually decrease through the digital rf power attenuator 223 corresponding to the area, it is equivalent to that the device under test X moves from the center of the area to a direction away from the center. Similarly, in a plurality of signal regions, the magnitude change of the signal intensity indicates the change of the movement path of the device X under test. By simulating the moving path of the tested equipment and the change condition of the network signal, the effect of simulating the actual use scene (real network environment) of the tested equipment can be effectively achieved, and then the weak network test can be carried out on the tested equipment based on the simulated real network environment.
The path simulation shown in fig. 9 will be described in detail below by taking only the a1 region and the a2 region as examples.
As shown in fig. 7, 8 and 9, first, the control system 100 controls the signal strength of the wireless network signal corresponding to the a1 area to be strongest through the digital rf power attenuator 223 corresponding to the a1 area, controls the signal strength of the wireless network signal corresponding to the a2 area to be weaker than that of the a1 area through the digital rf power attenuator 223 corresponding to the a2 area, and controls the wireless network signal of the A3 area to be turned off (no signal output), and at this time, the device under test is made to be closest to the a1 area and connected to the wireless network corresponding to the a1 area.
Then, the signal of the area a1 is controlled to gradually weaken and turn off, the signal of the area a2 remains unchanged, and the signal of the area A3 remains in the off state, which corresponds to the situation that the device under test gradually moves from the area a1 to the area B1 and is connected to the wireless network corresponding to the area a 2.
Then, the signal for controlling the a1 region is kept unchanged, the signal for controlling the a2 region is gradually increased, and the signal for controlling the A3 region is continuously kept in the off state, which is equivalent to that the device under test gradually moves from the B1 region to the a2 region.
The above process describes the moving process of the device under test between the two signal areas a1 and a2 and the control method of the network signals corresponding to the two signal areas a1 and a2, respectively, wherein the process of the device under test connecting to the wireless network is as follows: the method comprises the steps of simulating network environments of various tested equipment in the process, including network environments under different wireless networks and network environments switched among different wireless networks, by using a wireless network corresponding to an A1 area, switching among wireless networks corresponding to A1 and A2 areas and a wireless network corresponding to an A2 area, so that the effect of simulating an actual use scene (a real network environment) of the tested equipment can be effectively achieved, and then the tested equipment can be subjected to a weak network test based on the simulated real network environment.
It should be noted that, in the present embodiment, the control system 100 may also control the quality (strength) of the network signal through a preset model function, where the preset model function may be a linear function, a parabolic function, an exponential function, or the like.
In this embodiment, by controlling the signal at the transmission end of the signal, compared with the existing weak network test, the simulation of the actual application scene of the device under test can be realized. Due to the characteristics of network signal transmission, the control of bandwidth, time delay, jitter, abnormal conditions and the like can be realized by controlling the strength of the network signal.
According to the system for simulating the weak network test environment, the wireless network signals to be tested are transmitted through the wireless network transmission device, the mobile communication network signals to be tested are transmitted through the mobile communication network transmission device, the wireless network signals transmitted by the wireless network transmission device are controlled through the control system, and the mobile communication network signals transmitted by the mobile communication network transmission device are controlled, so that the weak network test environment under different required network scenes is simulated, the tested equipment is connected with different networks in the simulated weak network test environment, and the weak network test of the tested equipment under different network scenes can be realized. The system is low in cost, easy to realize and copy and suitable for batched weak network testing, can simulate the actual use scene (real weak network environment) of the tested equipment and is convenient for weak network testing of the tested equipment, and therefore accuracy and stability of the weak network testing of the tested equipment can be improved. In practical application, the system simulates an actual application scene to carry out weak network test on the tested equipment, and can optimize the application program of the tested equipment, so that the stability of the application program of the tested equipment can be greatly improved, and the user loss caused by unfriendly user experience can be effectively prevented.
