And step S3, based on the radio frequency attenuation instruction, respectively attenuating the first radio frequency input signal and the second radio frequency input signal through the radio frequency attenuation module so as to enable the terminal STA to reside in the first AP.
Preferably, the attenuation of the first rf input signal and the second rf input signal by the rf attenuation module based on the rf attenuation instruction is specifically:

and selecting a second radio frequency attenuation channel for the second radio frequency input signal to pass through by the radio frequency attenuation module based on the second attenuation value contained in the radio frequency attenuation instruction and the channel number of the second radio frequency attenuation channel corresponding to the second attenuation value, so that the second radio frequency input signal is attenuated by the second radio frequency attenuation channel.
Specifically, if a radio frequency attenuation channel corresponding to the first attenuation value exists in the radio frequency attenuation module, directly selecting the radio frequency attenuation channel corresponding to the channel number according to the channel number corresponding to the first attenuation value in the radio frequency attenuation instruction to allow the first radio frequency input signal to pass through; if the radio frequency attenuation module does not have the radio frequency attenuation channel corresponding to the first attenuation value, selecting the radio frequency attenuation channel corresponding to the attenuation value closest to the first attenuation value according to the first attenuation value for the first radio frequency input signal to pass through, and selecting the radio frequency attenuation channel corresponding to the channel number for the first radio frequency input signal to pass through.
Similarly, if a radio frequency attenuation channel corresponding to the second attenuation value exists in the radio frequency attenuation module, directly selecting the radio frequency attenuation channel corresponding to the channel number according to the channel number corresponding to the second attenuation value in the radio frequency attenuation instruction to pass through a second radio frequency input signal; if the radio frequency attenuation module does not have the radio frequency attenuation channel corresponding to the second attenuation value, selecting the radio frequency attenuation channel corresponding to the attenuation value closest to the second attenuation value according to the second attenuation value for the second radio frequency input signal to pass through, and selecting the radio frequency attenuation channel corresponding to the channel number for the second radio frequency input signal to pass through.
It should be noted that, in the embodiment of the present invention, the first attenuation value for attenuating the first radio frequency input signal transmitted by the first AP is set to be the minimum, and the second attenuation value for attenuating the first radio frequency input signal transmitted by the second AP is set to be the maximum, so as to maximize the signal strength of the first radio frequency input signal output by the test device, and ensure that the terminal STA can initially reside in the first AP no matter how much the switching threshold of the terminal STA is.
In addition, the terminal STA can be of various types such as CPE, mobile phone, platform or network card, and the terminal STA judges which AP is in communication connection with according to a preset switching threshold.
Preferably, the test method further includes, after the radio frequency attenuation module attenuates the first radio frequency input signal and the second radio frequency input signal, respectively:

And S4, controlling the power control module to continuously send a radio frequency attenuation instruction to the radio frequency attenuation module so as to continuously increase the first attenuation value and continuously decrease the second attenuation value, and judging whether the resident state of the terminal STA is changed from the resident state of the first AP to the resident state of the second AP in real time in the process that the power control module continuously sends the radio frequency attenuation instruction to the radio frequency attenuation module.
It should be noted that, at this time, since the terminal STA resides in the first AP, in order to verify the WAPI switching function of the terminal STA, the power control module needs to be controlled on the Web operation interface to continuously send the radio frequency attenuation instruction to the radio frequency attenuation module, so that the first attenuation value for attenuating the first radio frequency input signal is larger and larger, and the second attenuation value for attenuating the second radio frequency input signal is smaller and smaller, so that the signal strength of the first radio frequency input signal after being output by the testing device is gradually reduced to be lower than the switching threshold of the terminal STA, and the signal strength of the second radio frequency input signal after being output by the testing device is gradually increased to be higher than the access threshold of the terminal STA.
When the signal strength of the first radio frequency air interface signal is smaller than the switching threshold of the terminal STA and the signal strength of the second radio frequency air interface signal is larger than the access threshold, if the WAPI switching function of the terminal STA is normal, the resident state of the terminal STA is changed from being resident at the first AP to being resident at the second AP, so that the embodiment of the invention can verify whether the terminal STA can effectively perform WAPI switching by judging whether the resident state of the terminal STA is changed from being resident at the first AP to being resident at the second AP.
The first radio frequency air interface signal is the attenuated first radio frequency input signal, and the second radio frequency air interface signal is the attenuated second radio frequency input signal.
It should be noted that, since the switching threshold and the access threshold of each terminal STA are inconsistent, the purpose of the embodiment of the present invention is to manufacture a WAPI switching condition, gradually weaken the signal strength of the first radio frequency air interface signal, and enhance the signal strength of the second radio frequency air interface signal, so that the WAPI switching function of the terminal STA to be tested can be triggered no matter what the switching threshold and the access threshold of the terminal STA to be tested are, thereby verifying the validity of the WAPI switching function of the terminal STA to be tested.

Specifically, when the residence state of the terminal STA is changed from residence at the first AP to residence at the second AP, it is indicated that the terminal STA can switch APs in time when the output signal strength of the first AP is lower than the switching threshold value, and when the output signal strength of the second AP is higher than the switching threshold value, it is determined that the WAPI switching function of the terminal STA is normal, at this time, a first attenuation value and a second attenuation value when the terminal STA performs the WAPI switching are recorded, and the WAPI switching process includes that the terminal STA jumps from the first AP and the terminal STA accesses the second AP, and the WAPI switching threshold value of the terminal STA can be obtained by combining the preset initial output powers of the first AP and the second AP, so as to realize detection and verification of the WAPI switching performance of the terminal STA of different manufacturers.
It should be noted that, when the residence state of the terminal STA is not changed, the terminal STA still resides in the first AP, or the terminal STA does not reside in the first AP, or resides in the second AP, which indicates that the terminal STA cannot effectively perform the WAPI handover, so it is determined that the function of the WAPI handover of the terminal STA is abnormal.
It should be noted that, the technical effects that can be achieved by the WAPI switching test method provided by the embodiment of the present invention are the same as those achieved by the WAPI switching test device described in any embodiment of the first aspect, and are not described herein again.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
