However, the detection of the radio frequency channel needs to be performed by means of external special equipment at present, because the cost problem is that the detection equipment is difficult to be arranged at a general after-sale point, how to timely and accurately determine whether the machine in the hand of a customer has the abnormality of the radio frequency channel is very helpful for improving the satisfaction degree of customer experience and brand image.
The existing after-sale processing method generally compares the signal strength of a same machine with that of a user under the condition of actually using a network, and confirms whether the mobile phone of the user is abnormal or not according to the signal strength, so that the obvious defect is that only whether the quality of received signals is different or not can be detected. Secondly, even if the same operator card is used, there is a possibility that two mobile phones are not registered in the same base station or system, which results in inaccurate compared data. Moreover, for the machines which cannot be confirmed on site, products need to be sent back to research and development departments for professional analysis, so that the problem processing efficiency is low, and the customer satisfaction is poor.

The first terminal uses front end Transmission (TXM), the transmission front end is actually a large switch, and is used for switching different radio frequency paths to the antenna end to meet different frequency bands, fig. 5 is an internal schematic block diagram of front end transmission, a coupler (i.e. a coupling circuit) is integrated inside, the coupler is output back to the first terminal through a CPL pin, an ANT end is used for connecting the antenna end, and TRx1-TRx14 are used for connecting different radio frequency paths; the single pole multiple throw switch in the figure is used to connect different frequency bands to the antenna terminal, and the Coupler (Directional Coupler) is used to couple the power of the ANT path out through the CPL pin.
It should be noted that the power passing through the coupler to the CPL is attenuated by a fixed amount, ensuring that a significant portion of the power is transmitted to or received from the antenna by the first terminal.
The transmission process of the first radio frequency signal is as follows: CPU converts the data to be transmitted into digital signal and sends it to radio frequency Transceiver (TR), TR converts the signal into analog signal and crossmodulates it with carrier wave to generate original transmitting waveform, TR sends the original wave to power amplifier with low power to amplify the signal, the amplified signal is sent to transmitting front end (for TDD signal, it is directly sent to transmitting front end by TR through matching, for FDD signal, it is passed through duplexer, then the common end of duplexer is connected to transmitting front end), transmitting front end connects antenna end ANT to current transmitting channel by switch, then the signal is radiated by antenna. A signal with a fixed attenuation is coupled into the CPL and into the TR in the transmit front-end.
And S303, the second terminal receives the first radio frequency signal and confirms the receiving power, obtains the preset transmitting power and the self-coupling power, and obtains a detection result for detecting the radio frequency channel to be detected according to the preset transmitting power, the self-coupling power and the receiving power.

And if the difference between the preset transmitting power and the self-coupling power is within a first tolerance range, and the difference between the preset transmitting power and the receiving power and the difference between the self-coupling power and the receiving power are not within the first tolerance range, judging that the radio frequency path to be tested is abnormal during factory calibration.
And according to the preset transmitting power, the self-coupling power and the receiving power, whether the transmission of the radio frequency channel to be detected is abnormal can be detected, whether the coupling circuit is abnormal can be judged, and the radio frequency channel to be detected is abnormal in factory calibration.
S304, the first terminal receives a second instruction for detecting the radio frequency path, wherein the second instruction comprises the radio frequency path to be detected.
S305, the first terminal controls the radio frequency channel to be detected to be conducted so as to detect a second radio frequency signal emitted by a second terminal, confirms detection power and sends the detection power to the second terminal.
And selecting an APK menu of the second terminal to a transmitting mode, selecting a frequency band of the first terminal to be tested, selecting a transmitting system and power (at the moment, the power is selected to be the lowest), and setting an adjustable attenuator for attenuation if necessary.
And the first terminal is tuned to a receiving inspection mode, a frequency band and a system to be transmitted by the second terminal are selected and clicked to start testing, the first terminal can automatically switch the TXM switch to a receiving channel of a radio frequency channel to be tested, and a user starts to detect signals after pressing a transmitting button of the second terminal.
S306, the second terminal obtains a detection result for detecting the radio frequency channel to be detected according to the power of the second radio frequency signal and the detection power.
The second terminal obtains the power (i.e. the detection power) of the second radio frequency signal detected by the first terminal, and obtains the detection result according to the power and the power of the second radio frequency signal transmitted by the second terminal.
Specifically, if the difference between the power of the second radio frequency signal and the detection power is within a second tolerance range, it is determined that the radio frequency path to be detected is normally received, otherwise, it is determined that the radio frequency path to be detected is abnormally received.
