(1) Harmonic signal

Harmonics are components of frequencies greater than an integral multiple of the fundamental frequency obtained by fourier-series decomposition of periodic non-sinusoidal ac components, and are generally called harmonics. The harmonics may be the first harmonic, second harmonic, third harmonic, etc. of the fundamental.

A harmonic of a signal used by a certain module of the terminal may partially overlap with a frequency of a radio frequency signal transmitted by other modules, thereby possibly causing co-channel interference to the transmission of the radio frequency signal.

(2) Non-stand alone (NSA) and Stand Alone (SA) networking modes

In the process of mobile communication development, the NSA networking mode is a networking mode which appears when two-generation networks alternately evolve. Currently, the networking mode of 5G can be divided into two networking modes, namely NSA networking mode and SA networking mode, and the networking modes of 2G, 3G and 4G are all SA networking modes. In the evolution process, the 4G networking mode is gradually replaced by a 5G NSA networking mode, and then replaced by a 5G SA networking mode.

Currently, in the NSA networking mode, a core network is still a 4G core network, i.e., an Evolved Packet Core (EPC), and base stations of both 4G and 5G exist in an access network. In the SA networking mode, the core network is a 5G core network (5GGore), and the access networks are 5G base stations. Therefore, communication between a base station and a terminal in the NSA networking model requires a 4G signal as a control signal, and a 5G signal as a data signal; and the communication between the base station and the terminal in the SA networking model requires that the control signal and the data signal are both 5G signals.

In the process of using the frequency band, the frequency bands with different frequencies from 2G to 5G are divided, so that in the SA networking mode, the frequency band that can be used by the wireless signal is a frequency band in one of the frequency ranges from 2G to 5G, and may be a frequency band of 6G in the future. The frequency band used by the wireless signal in the NSA networking mode may be a frequency band with two frequency ranges of 4G and 5G, and may also be a frequency band with two frequency ranges of 5G and 6G in the future.

(3) Sensitivity of reception

The reception sensitivity of wireless transmission is similar to the hearing of people when they are communicating, and is the lowest signal strength (electromagnetic wave energy) that the receiver can receive and work properly. Improving the reception sensitivity of the signal may enable the wireless product to have a stronger ability to capture weak signals. The reception sensitivity may be expressed as S ═ 10lg (ktb) + NF + SNR. Wherein: s is the receiving sensitivity, and the unit is dBm; k is Boltzmann constant, and the unit is J/K; t is the absolute temperature in K; KT is the thermal noise power per hertz (Hz) at the current temperature; b represents the signal bandwidth in Hz; KTB represents the thermal noise power over the bandwidth; NF represents the noise figure of the system in dB (similar to the ambient figure); snr (signal to noise ratio) represents the signal-to-noise ratio required for demodulation, and is expressed in dB.

Sensitivity refers to the minimum signal power (signal strength) that a receiver can receive at a certain error rate (SER). That is, it is necessary to explain an error condition when detecting sensitivity while giving a sensitivity parameter. In the process of detecting the receiving sensitivity by the receiver, a minimum bit error rate (namely, a return bit error rate) can be determined, after the minimum bit error rate is determined, the receiver can adjust the bit error rate downwards (namely, downward detection) by continuously reducing the signal transceiving power, and when the bit error rate is reduced to the minimum bit error rate, the sensitivity detected by the receiver can be determined as the receiving sensitivity.

In wireless communication systems, signals are susceptible to interference. In the process of wireless communication of the terminal, the quality of the wireless radio frequency signal is directly related to the experience of the user. Therefore, in the laboratory stage, it is often necessary to test and evaluate the interference of the radio frequency signal of the terminal to ensure the communication quality of the terminal.

Fig. 1 is a schematic structural diagram of a radio frequency interference testing system of a terminal according to an embodiment of the present application. As shown in fig. 1, the apparatus for testing radio frequency interference of the terminal may include a comprehensive tester 101, an industrial personal computer 102, a shielding box 103, and a terminal 104. The terminal 104 can be placed in the shielding box 103, so that the influence of other interference on the test result in the test process can be avoided, and the accuracy of the test result is ensured. The industrial personal computer 102 can be respectively connected with the terminal 104 and the comprehensive tester 101, and the industrial personal computer 102 can control the comprehensive tester 101 and the terminal 104 to complete testing. The shielding box 103 may be connected to the comprehensive tester 101, and may complete the transmission of signals between the comprehensive tester 101 and the terminal 104.

The industrial personal computer 102 can control the terminal 104 and the comprehensive tester 101, and the comprehensive tester 101 can test signals between the terminal and the comprehensive tester. For example, when the terminal 104 communicates with the integrated instrument 101, the integrated instrument 101 may measure the reception sensitivity of the radio frequency signal, or may measure the reflection loss of the radio frequency signal.

In the test system of fig. 1, there are possible test modes:

in a possible implementation manner, considering that interference situations of the terminal in different directions are different, the above-mentioned radio frequency interference testing system can be placed in a darkroom, and the interference result is tested once every time the terminal is rotated.

In the above-described embodiment, it is possible to complete the interference test of the terminal in different directions and the interference test in the case of avoiding the interference of the placement position of the shield box to the terminal antenna. However, the above embodiments are all interference tests performed under the condition that the terminal only uses a single communication function, and in the process of the actual use of the terminal, specific use scenarios are often different, and in these scenarios, some self modules of the terminal are used, and may also cause interference to their own radio frequency signals. For example, when a user uses the terminal to take a picture while accessing the internet via WiFi, when the camera module is running, a Mobile Industry Processor Interface (MIPI) signal generated by a Flexible Printed Circuit (FPC) of the camera and a harmonic signal of a main clock MCLK signal may interfere with the WiFi signal. In the case where a user uses the mobile data network while listening to music, the audio module generates harmonics that may interfere with the cellular mobile signal. When a user uses a mobile data network while connecting a wireless headset (bluetooth) to the terminal, harmonics generated from the bluetooth signal may interfere with signals of the mobile data network. In the terminal scenes, the wireless radio frequency interference of the terminal measured by the testing method is inaccurate.

In view of the above existing problems, embodiments of the present application provide a method and a system for testing radio frequency interference of a terminal. The industrial personal computer can control the terminal to start a corresponding test scene (such as a camera shooting scene, a music scene, a wireless earphone scene, a charging scene and the like) and instruct the comprehensive tester to start testing according to a specific frequency band. After the test of the comprehensive tester is finished, the test result can be sent to the industrial personal computer. Therefore, the accuracy of the wireless radio frequency interference test of the terminal under different scenes is ensured.

Referring to fig. 2, fig. 2 is a schematic structural diagram of another wireless radio frequency interference testing system of a terminal according to an embodiment of the present disclosure, where the system may include an integrated tester 201, an industrial personal computer 202, a shielding box 203, a terminal 204, and a cloud server 205.

The comprehensive tester 201 is used for performing radio frequency interference testing on the terminal 204 based on the control of the industrial personal computer 202. The signals tested by the integrated tester 201 may be radio frequency signals such as 2G, 3G, 4G, 5G, WiFi and bluetooth, and the integrated tester 201 may test the receiving sensitivity of these radio signals. The integrated tester 201 can test the different types of radio frequency signals by controlling the frequency band of the radio signals. It should be understood that the integrated tester 201 may correspond to a base station in a cellular mobile network, an Access Point (AP) in WiFi, and the like.

The industrial personal computer 202 is used for controlling the terminal 204 and the comprehensive tester 201 to complete the interference test of the radio frequency signal according to the test task of the cloud server 205. The industrial personal computer 202 may be a computer device, e.g., a computer, etc., having an associated testing algorithm. The industrial personal computer 202 may be connected to the cloud server 205 (may be connected to the internet), and the industrial personal computer 202 receives a test task from the cloud server 205 or reports a test result to the cloud server 205. The industrial personal computer 202 may be connected to the integrated tester 201 through a General Purpose Interface Bus (GPIB), and may control the integrated tester 201 to complete testing. The industrial personal computer 202 may also be connected to the terminal 204 through a Universal Serial Bus (USB) interface, and may control a current test scenario of the terminal 204.

The shielding cage 203 may be used to shield interfering signals around the terminal 204. The shielding box 203 may be a triangular pyramid coupling tower (also called triangular pyramid shielding box) or other types of shielding devices. The terminal 204 may be placed inside the shielded box 203 so that the accuracy of the test may be ensured. In addition, the shielding box 203 may be connected to the integrated tester 201 through a long rf cable.

The terminal 204 is a device under test, and may be any terminal device having a wireless communication function, such as a mobile phone, a tablet, a personal computer, and the like.

The cloud server 205 may be configured to define a test scenario, a test frequency point or frequency band, and other test requirements of the terminal 204. For example, the user may determine a test scenario, a test frequency band or point, a test mode, and the like through the cloud server 205.

The radio frequency interference test system of the terminal corresponding to fig. 2 is a test system in an SA networking mode, that is, the test mode of the structure of fig. 2 is an SA test mode.

In the NSA networking mode, control signaling and data information between the terminal and the comprehensive tester are not wireless signals in the same frequency band, so that the comprehensive tester and the shielding box need to be respectively transmitted through two long radio frequency cables. Referring to fig. 3, fig. 3 is a schematic diagram of a system for testing radio frequency interference of a terminal according to another embodiment of the present application. The system of fig. 3 is a schematic structural diagram in the NSA networking mode. As shown in fig. 3, the system may include an integrated tester 301, an industrial personal computer 302, a shielding box 303, a terminal 304, a cloud server 305, and a power divider 306.

The power divider 306 is a device that divides a single input signal into two or more paths to output equal or unequal energy, and may also combine the multiple paths of signals into a single output, which may also be referred to as a combiner. The interface of the power divider 306 after being combined may be connected to the shielding box 303, and the interfaces of the two paths of signals after being divided may be connected to the comprehensive tester 301 through the long rf cable, respectively.

In the NSA networking mode, since the control signal and the data signal need to be transmitted through different paths, the two signals may be transmitted between the comprehensive tester 301 and the shielding box 303 through the power divider 306 during the testing process. At present, two long radio frequency cables of the system of fig. 3 can transmit a 4G frequency band and a control signal and a 5G frequency band data signal respectively, so that the wireless radio frequency interference test method of the embodiment of the present application can be used in different networking modes, and has a wide application range and higher test flexibility and practicability.

The integrated instrument 301, the industrial personal computer 302, the shielding box 303, the terminal 304 and the cloud server 305 in fig. 3 may refer to the related descriptions of the integrated instrument 201, the industrial personal computer 202, the shielding box 203, the terminal 204 and the cloud server 205 in fig. 2 in sequence, which are not described herein. Wherein, fig. 3 and fig. 2 correspond to different test modes respectively, and fig. 3 corresponds to NSA test mode; fig. 2 corresponds to the SA test mode.

It should be noted that the systems in fig. 2 and fig. 3 may or may not include a cloud server. Under the condition that the cloud server is included, variables in the testing process can be directly controlled at the cloud by a user, and the operation is simpler and more efficient.

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a method for testing radio frequency interference of a terminal according to an embodiment of the present disclosure. The method is applied to the system corresponding to fig. 2 and fig. 3, and the system includes a cloud server. As shown in fig. 4, the method for testing radio frequency interference of the terminal may include the following steps:

s401, the cloud server issues a test task to the industrial personal computer.

The test task may include scenario information, frequency information. In addition, the test task may also include mode information (i.e., test mode). After the cloud server determines the scene information, the frequency information and the mode information, a test task can be sent to the industrial personal computer. Correspondingly, the industrial personal computer can receive the test tasks from the cloud server.

Three types of information that a test task may include are described separately below: scene information, frequency information, and mode information.

(1) Scene information (scene can be called test scene or test terminal scene)

The scene information is information of a scene used by the terminal in the test. The types of scene information may be classified into various types, for example, a music scene, a camera scene, a vibration scene, a bright and dark screen scene, a file transfer scene, a wired headset scene, a wireless headset scene, a screen projection scene, a USB file transfer scene, a game scene, a charging scene, and the like. The scenario information may include one or several of the above scenarios, that is, the scenario of one or several of the terminals may be set for each test.

Several test scenarios are specified below:

the music scene is a scene in which the terminal plays music. In the process of playing music by an audio module of the terminal, the harmonic waves of the audio generated by the audio module can be the same as the frequency of the wireless radio frequency signal, so that wireless radio frequency interference can be caused. Therefore, the music scene can be taken as one of the test scenes in the test process.

The shooting scene is a scene in which the terminal uses a camera application. The shooting scene can be a shooting scene applied by using a terminal camera and can also be a video recording scene. In the process of shooting by the terminal, harmonic waves of signals generated by a camera module of the terminal can interfere with radio frequency signals, so that a shooting scene can be used as one of test scenes in the test process.

The vibration scene is a scene that the motor is started by the terminal to generate vibration. Harmonic waves generated by the circuit module related to the motor vibration may cause interference to the radio frequency signal, and therefore, a vibration scene can be used as one of the test scenes in the test process.

The bright screen scene is a scene that the display screen of the terminal is bright. For example, a cell phone is browsing web pages. Harmonic waves of signals possibly generated by circuit modules or devices related to a display screen of the terminal may cause certain interference on the radio frequency signals, and therefore, a bright screen scene can be used as one of test scenes in the test process.

The file transmission scenario is a scenario in which the terminal performs file transceiving with other devices through bluetooth, for example, the glory 50 starts a glory sharing function to transmit or receive a file. In a file transfer scenario, harmonics of the generated signal of the bluetooth module of the terminal device may interfere with the transmission of other radio frequency signals.

The wired headset scene is a scene in which the terminal uses a wired headset, for example, a scene in which a user listens to music or watches videos through the wired headset. Harmonic interference can also be generated in the using process of the wired earphone, so that a wired earphone scene can be used as one of test scenes in the test process.

The wireless headset scene is a scene in which the terminal uses the wireless headset. In a scenario where the terminal uses the wireless headset through bluetooth, harmonic waves generated by the bluetooth module may cause interference to other types of wireless radio frequency signals. Therefore, the wireless earphone scene can be used as one of the test scenes in the test process. In addition, the wireless earphone scene can also be expanded to other scenes using Bluetooth.

The screen projection scene can be a scene in which the terminal uses a wireless screen projection function, and can also be a scene in which the terminal is connected with other equipment through a wire to project a screen. In the screen projection scene of the terminal, harmonic waves of signals generated by relevant modules of the terminal may interfere with radio frequency signals, so that the screen projection scene can be used as one of test scenes in the test process.

The USB file transmission scene is a scene that the terminal equipment transmits files with other equipment through a USB interface. When the terminal transmits the file through the USB interface, certain harmonic waves may be generated by the relevant modules for data transmission, and the harmonic waves may cause interference to the radio frequency signal being transmitted.

The game scene is a scene in which the terminal uses a game application. During the process of the terminal running the game related application, the harmonic wave of the signal generated by the related module may cause interference by the transmitted wireless radio frequency signal.

The charging scene is a scene in which the terminal is charging through the USB interface. During the charging process, the harmonic wave of the signal of the charging module of the terminal may cause interference to the radio frequency signal.

It should be noted that in all the scenarios of the test terminals described above, the terminals are in a state of communicating with the integrated tester. The terminal needs to specifically test the functionality of the scenario. For example, a mobile phone with a photographing function may test the above-mentioned shooting scene.

In the above scenario, the test scenarios described in the terminal are all scenarios that may be encountered by the user when the user is at a specific terminal. For example, a music scene may be a scene in which a user listens to music while using a search engine; the shooting scene may be a scene in which the user takes a picture while making a call, and the like, and this is merely an example and is not a limitation.

(2) Frequency information

The frequency information is frequency band and/or frequency point information of a wireless radio frequency signal transmitted between the terminal and the comprehensive tester in the testing process. The frequency information (measured frequency) may be information of a certain frequency point, information of a certain part of frequency band, or information of both, without limitation.

It should be noted that, in the test process using different frequencies, different frequency bands may correspond to different wireless signals. For example, the wireless signals in the frequency band of 800MHz-1800MHz are 2G signals; the wireless signals in the frequency band of 1920MHz-1935MHz are 3G signals; the wireless signals in the frequency band of 2575MHz-2635MHz are 4G signals; the wireless signals in the frequency band of 3500MHz-3600MHz are 5G signals; the wireless signals in the frequency band of 2.45G-5G are WiFi signals, etc. The foregoing is illustrative only and is not limiting.

It should be further noted that, when testing is performed according to the frequency information in the test task, the test frequency of the integrated tester may be 1 time or multiple times, and the frequency information in the test task refers to the frequency bands or frequency points included in the frequency bands or frequency points that all need to be tested.

(3) Mode information

The mode information is networking mode information of a network to which the terminal is accessed. The mode information may be one of an SA mode and an NSA mode. For example, "1" indicates an SA mode, and "0" indicates an NSA mode.

It should be noted that both the SA mode system shown in fig. 2 and the NSA mode system shown in fig. 3 can be connected to the same cloud server through the internet, or can be connected to different cloud servers respectively. Further, the SA mode and the NSA mode can be switched during actual testing. In one case, the cloud server may be connected to both SA and NSA systems in different modes through the internet, for example, the cloud servers in fig. 2 and 3 are the same cloud server. In another case, the cloud server may be connected to a system in an SA or NSA mode through the internet, and when a test involves a system in another mode, the connection mode between the shielding box and the comprehensive tester in the current mode may be adjusted, so as to switch the system in fig. 2 and the system in fig. 3. For example, the power divider and the two rf long cables between the shielding box and the comprehensive tester in fig. 3 are replaced by one rf long cable, that is, the NSA mode system is adjusted to the SA mode.

Several methods of determining the networking mode are described below:

the method comprises the following steps: and determining a networking mode based on the mode information determined by the cloud server.

In one case, the cloud server correspondingly issues mode information based on different networking modes of the industrial personal computer. The cloud server knows the networking mode of the industrial personal computer connected with the cloud server through the Internet, and after determining the current mode information, the cloud server can issue a test task to the industrial personal computers with the same networking mode, wherein the issued test task comprises the mode information. For example, the cloud server knows that there are 5 industrial personal computers connected to itself via the internet, 3 of which are SA modes and two of which are NSA modes. When the networking mode of the cloud server is the SA mode, the cloud server can send a test task to one industrial personal computer in the 3 SA modes, and the test task comprises the mode information.

Under another condition, the cloud server directly issues mode information, and the industrial personal computer adjusts the mode of the industrial personal computer based on the mode information. After the cloud server determines the mode information, a test task can be issued to an industrial personal computer in any known networking mode. After the industrial personal computer receives the mode information included in the test task, whether the networking mode of the industrial personal computer is the same as the networking mode of the industrial personal computer can be judged based on the mode information. Under the same condition, the networking mode does not need to be adjusted; and under different conditions, the networking mode of the self is adjusted to be the mode with the same mode information. For example, the mode information sent by the cloud server is "1" (representing an SA networking mode), and after receiving the mode information, the industrial personal computer compares the networking mode thereof with "0" (representing an NSA networking mode). The industrial personal computer can display prompt information to prompt a user to switch a networking mode. The user can adjust the connected mode between integrated tester and the shielded cell to switch the networking mode of industrial computer to be "1". The above networking mode switching manner may be specifically referred to, and details are not repeated.

The method 2 comprises the following steps: and determining a networking mode based on the frequency information determined by the cloud server.

And when the cloud server issues the test task to the industrial personal computer, the test task can include frequency information but not mode information.

In one possible implementation, the cloud server or the industrial personal computer may determine the networking mode based on the frequency information. In the NSA networking mode, the wireless signals corresponding to the two generations of cellular mobile communication technologies are involved in the test process, for example, the frequency information includes frequency bands in the frequency bands of 4G and 5G. In the SA networking mode, only the frequency band range of a certain generation of cellular mobile communication technology is involved in the test process, for example, the frequency information only includes the 4G frequency band. Therefore, the networking mode can be determined according to the frequency band range of the frequency information. That is, when the frequency band range in the frequency band information is only in the frequency band range of the first generation cellular mobile communication technology, the networking mode can be determined to be the SA mode; when the frequency band range in the frequency band information is within the frequency band range of two successive generations of cellular mobile communication technologies, it may be determined that the networking mode is the NSA mode.

In one case, after the cloud server determines the frequency information, the networking mode may be determined based on the frequency information (refer to the above method). And will issue frequency information (refer to the relevant description in the mode 1) to the industrial personal computer corresponding to the networking mode.

In another case, the cloud server sends the frequency information to the industrial personal computer after determining the frequency information. After receiving the frequency information from the cloud server, the industrial personal computer may determine a networking mode based on the frequency information (refer to the above method), and then the cloud server may adjust its networking mode based on the determined networking mode (refer to the relevant description in the mode 1).

The method 3 comprises the following steps: the industrial personal computer reports mode information to the cloud server, and the cloud server determines the mode information and/or frequency information.

Under the condition that the industrial personal computer determines the networking mode of the industrial personal computer, the mode information of the industrial personal computer can be reported to the cloud server. After the cloud server receives the mode information from the industrial personal computer, the industrial personal computer based on different networking modes can issue test tasks. Namely, the cloud server can complete a test task of judging a certain frequency band based on the mode information. The cloud server can send the test task to the terminal equipment under the condition that the test task can be completed; otherwise, it is not sent.

For example, when the mode of the industrial personal computer is the NSA mode, the cloud server determines that the test frequency band in the current test task is the 4G frequency band (however, the NSA mode tests wireless signals of the 4G and 5G frequency bands), and cannot send the test task to the industrial personal computer. When the mode of the cloud server receiving the industrial personal computer is the SA mode, the cloud server determines that the test frequency band in the current test task is the 4G frequency band (the SA mode tests wireless signals of one of the 2G, 3G, 4G and 5G frequency bands), and can send the test task to the industrial personal computer.

The user may control some variables in the test process (e.g., test frequency, scenarios, etc.). Such as the test scenario and frequency of tests described above, etc. Namely, the user can access the cloud server through the electronic device and determine the variables in the test.

Exemplarily, fig. 5 is a schematic view of a user operation interface disclosed in an embodiment of the present application. As shown in fig. 5 (a), the electronic device may display a user operation interface of the cloud server. The user interface may include a first screen that may include associated controls to determine the test information. The test information may include frequency information and scenario information. The frequency information may be divided into a frequency band and a bandwidth. The controls for determining the frequency band can comprise a test frequency band such as an N41 control, an N77 control, an N78 control, an N79 control and the like, and the controls for determining the bandwidth can comprise a 100MHz control, a 60MHz control, a 40MHz control, a 20MHz control and the like. The control for determining the scene information may include a music scene control, a camera shooting scene control, a vibration scene control, a charging scene control, a screen projection scene control, a USB file transmission scene control, a bright screen scene control, a bluetooth scene control, and the like.

As shown in fig. 5 (a), the user may click on the bin N77 control, the bandwidth 40MHz control, the camera scene control, and the start control. In response to the above-described user operation, the user operation interface may display a second screen in which a control in the first screen has been changed to a dark color, indicating that a test task is determined, as shown in fig. 5 (b). The cloud server may then begin issuing test tasks.

The above N41, N77, N78, and N79 are used to indicate different frequency band numbers of the 5G frequency band, and the frequency band numbers can be used in testing of radio frequency signals. In addition, cellular mobile communication networks of different generations may need to use different frequency band numbers, which is not limited herein.

S402, the industrial personal computer issues a scene instruction to the terminal based on the test task.

After the industrial personal computer receives the test task from the cloud server, the scene instruction can be determined based on the test task. When the test task includes the scene information, the scene instruction may be determined according to the scene information. And then the industrial personal computer can issue a scene instruction to the terminal. Correspondingly, the terminal can receive a scene instruction from the industrial personal computer. The scene instruction corresponds to a test scene and is used for indicating the terminal to start the test scene in the test process. The scene command is an operation command, and the terminal can respond to the operation command to start the corresponding application or function, so that the terminal enters a test scene. For example, the scene instruction issued by the industrial personal computer is an instruction for starting a shooting scene.

When the industrial personal computer receives a test task from the cloud server and contains scene information (shooting scene), the test scene can be determined to be the shooting scene according to the scene information, and then a scene instruction can be sent to the terminal, wherein the scene instruction is used for instructing the terminal to start a camera scene.

In a possible implementation mode, when the industrial personal computer can complete the test task only by carrying out one-time test in the test task, the industrial personal computer can directly issue a scene instruction to the terminal.

Illustratively, when the frequency information included in the test task received by the industrial personal computer is a certain frequency point and the scene information is a bright screen scene, the industrial personal computer determines to perform testing only under the frequency point and the bright screen scene, and directly descends to issue a scene instruction to the terminal.

In another possible implementation manner, when the industrial personal computer can complete the test task only by performing multiple tests in the test task, the industrial personal computer can perform combination according to the scene information and the frequency information of the test task to determine that the tests are performed under the conditions of the scene and the frequency. In addition, the industrial personal computer also needs to determine a test sequence under several test conditions and issue scene instructions in sequence.

For example, when the test task received by the industrial personal computer includes a piece of frequency information (2550MHz-2650MHz), bandwidth information 50MHz, and two kinds of scene information (a game scene and a camera scene), the industrial personal computer may determine a test sequence and a corresponding relationship between a test frequency and a test scene corresponding to the test.

TABLE 1

Test sequence	Testing frequency	Test scenario
			1	2550MHz	Game scene
2	2600MHz	Game scene
			3	2650MHz	Game scene
4	2550MHz	Camera scene
			5	2600MHz	Camera scene
6	2650MHz	Camera scene

Table 1 exemplarily discloses a table of correspondence and test order of test frequencies and test scenarios. After the industrial personal computer determines the test sequence, a scene instruction for indicating to start a game scene can be issued to the terminal during the first test; during the second test, a scene instruction for indicating to start the game scene can be issued to the terminal; … …, respectively; during the sixth test, a scene instruction for instructing to start the shooting scene can be issued to the terminal.

Before the industrial personal computer issues the scene instruction to the terminal, the industrial personal computer can issue a communication starting instruction to the terminal. After the terminal receives a communication starting instruction from the industrial personal computer, the terminal can start the communication capacity between the terminal and the comprehensive tester. Namely, the terminal and the integrated instrument are physically connected through the USB interface, but the terminal and the integrated instrument cannot transmit and receive information, and communication can be performed after the terminal turns on the communication capability.

For example, the industrial personal computer may issue an instruction (communication start instruction) to close the flight mode to the terminal. After the terminal receives the instruction for closing the flight mode, the flight mode can be closed, and at the moment, the terminal can be normally connected with the comprehensive tester and can perform operations such as registration or testing. After the test is finished, the industrial personal computer can issue an instruction for starting the flight mode to the terminal. After the terminal receives the instruction for starting the flight mode, the flight mode can be started, and at the moment, the terminal can be disconnected with the comprehensive tester. Wherein, under the condition of no test, the terminal can default to the starting flight mode.

For example, the industrial personal computer may issue a power-on instruction (communication start instruction) to the terminal. The terminal can be started after receiving the starting instruction, and at the moment, the terminal can be normally connected with the comprehensive tester and can perform operations such as registration or testing. After the test is finished, the industrial personal computer can issue a shutdown instruction to the terminal. After the terminal receives the shutdown instruction, the terminal can be closed, and at the moment, the terminal can be disconnected with the comprehensive tester.

The scene command can be a serial number in a scene serial number rule agreed between the terminal and the comprehensive tester, and after the terminal receives the scene command, the terminal can determine a started scene according to the known scene serial number rule.

Numbering system 1: one number for each scene.

TABLE 2

Illustratively, table 2 is a mapping rule between scenes and numbers. When the scene instruction received by the terminal is 0010, the terminal can start a vibration scene according to the rule; when the scene instruction received by the terminal is 1001, the terminal may start a screen projection scene, and the like. Wherein, the number and the scene should be in a one-to-one correspondence relationship.

Numbering system 2: the number is determined based on the inclusion relation and the juxtaposition relation of the scene.

The large test scenario in a test scenario may include several specific scenarios, and the large test scenario may be determined according to the first number, and a specific scenario may be determined according to the second number.

Illustratively, the numbers in table 2 above may represent first numbers, in the imaging scene numbered 0001, the imaging scene may specifically include 4 specific scenes, namely, a front camera scene, a main camera scene, a wide-angle imaging scene, and a macro imaging scene, and the second numbers may be four numbers, namely, a front camera scene 01, a main camera scene 02, a wide-angle imaging scene 03, and a macro imaging scene 04.

And S403, the terminal starts the corresponding scene based on the scene instruction.

After the terminal receives the scene instruction from the industrial personal computer, the corresponding scene can be started based on the scene instruction. For example, when the scene instruction indicates that the test scene is a shooting scene, the terminal starts a camera application to start shooting; when the scene instruction indicates that the test scene is a music scene, the terminal starts a music application and starts to play audio; when the scene instruction indicates that the test scene is the wireless headset scene, the terminal starts the bluetooth, connects with the wireless headset, and the like, the descriptions in S401 may be referred to for the numbers of other specific scenes, and the descriptions in S402 may be referred to for the description of the scene instruction, which is not repeated.

And S404, the industrial personal computer sends a control instruction to the comprehensive measuring instrument.

And the industrial personal computer sends a control instruction to the comprehensive measuring instrument. Correspondingly, the comprehensive tester receives a control command from the comprehensive tester.

The control instructions may include feedback error rate and frequency information. The frequency information may include range information and bandwidth information of the test frequency, and/or frequency point information of the test. For example, the frequency information is N41, 20 MHz. The frequency band tested is indicated as the frequency band with the frequency band number N41, and in this frequency band, the test is performed every 20 MHz. The return error rate is the error rate standard of the comprehensive tester for testing the receiving sensitivity in the testing process.

The industrial personal computer can determine the return error rate by the following method:

in a possible implementation manner, the industrial personal computer determines the feedback error rate based on the test task, at this time, the test task may further include the feedback error rate, and the industrial personal computer may issue the control instruction based on the test task. The user may input or select the feedback error rate through the user interface of the cloud server, and the specific method may refer to the related description in fig. 5, which is not repeated.

In another possible implementation manner, the industrial personal computer may store the return error rate, and before the industrial personal computer issues the control instruction, the stored return error rate may be determined as the return error rate in the control instruction. Wherein, the stored return error rate can be set by the user in advance. For example, a user can enter the test software system through the industrial personal computer to write back the value of the error rate.

In another possible embodiment, the cloud server may store a return error rate set by the user, and after the cloud server issues the test task to the industrial personal computer, the test task may further include the set return error rate. The industrial personal computer can then determine the return error rate based on the test task.

After the industrial personal computer receives the test tasks from the cloud server, the industrial personal computer can determine the corresponding relation between the test scenes and the test frequency and the test sequence according to the frequency information and the scene information in the test tasks. The scene information in the test task may include one or more scene information, such as a camera scene and a charging scene. The test frequency in the test task may include one or more frequency points capable of being tested. After the industrial personal computer determines the test frequency and the test scene in the test task, the test frequency and the test scene and the test sequence in each test can be determined according to the test frequency and the test scene in the test task. For example, when the scene information in the test task is a shooting scene and a charging scene, and the frequency band information is frequency points of 2580MHz, 2600MHz, and 2620 MHz. The industrial personal computer can arrange and combine the scene information and the frequency band information according to the sequence, thereby determining that the test is as follows: in the 1 st test, the test scene is a camera shooting scene, and the test frequency point is 2580 MHz; during the 2 nd test, the test scene is a camera shooting scene, and the test frequency point is 2600 MHz; in the 3 rd test, the test scene is a shooting scene, and the test frequency point is 2620 MHz; in the 4 th test, the test scene is a charging scene, and the test frequency point is 2580 MHz; during the 5 th test, the test scene is a charging scene, and the test frequency point is 2600 MHz; and in the 6 th test, the test scene is a charging scene, and the test frequency point is 2620 MHz. After the industrial personal computer determines the corresponding relation between the test scene and the test frequency and the test sequence, the scene instruction sent to the terminal is an instruction for indicating to start the shooting scene in the 1 st test, and the frequency information included in the control instruction sent to the comprehensive tester is 2580 MHz. During the 2 nd test, the scene instruction sent to the terminal is an instruction for instructing to start a shooting scene, and the frequency information included in the control instruction sent to the comprehensive tester is 2600 MHz. In the 3 rd test, the scene instruction sent to the terminal is an instruction for instructing to start a shooting scene, and the frequency information included in the control instruction sent to the comprehensive tester is 2620 MHz. During the 4 th test, the scene instruction sent to the terminal is an instruction for indicating to start a charging scene, and the frequency information included in the control instruction sent to the comprehensive tester is 2580 MHz. During the 5 th test, the scene instruction sent to the terminal is an instruction for indicating to start a charging scene, and the frequency information included in the control instruction sent to the comprehensive tester is 2600 MHz. During the 6 th test, the scene instruction sent to the terminal is an instruction for indicating to start a charging scene, and the frequency information included in the control instruction sent to the comprehensive tester is 2620 MHz.

In addition, the industrial personal computer can also issue a test stopping instruction to the comprehensive tester, and the test stopping instruction can indicate the comprehensive tester to stop the current test instruction. The industrial personal computer can also send registration information to the comprehensive tester, and the registration information is information used for registration between the comprehensive tester and the terminal.

Steps S402 and S404 do not limit the execution sequence. S402 may be performed first, and then S404; s404 may be executed first, and then S402 may be executed.

And S405, testing by the comprehensive tester based on the control instruction.

After the comprehensive tester receives the control instruction from the industrial personal computer, the test can be carried out based on the control instruction.

Under the condition that the control instruction comprises frequency information and a return error rate, the comprehensive tester can determine the minimum value of the error rate in the downward detection process based on the frequency of the wireless radio-frequency signal in the frequency information test process and the return error rate. For example, when the frequency information is 2515Hz, the frequency of the radio frequency signal between the comprehensive tester and the terminal is 2515 Hz. When the return error rate is 5%, the comprehensive tester continuously reduces the error rate test sensitivity, when the error rate reaches 5%, the error rate is not reduced any more, and the current sensitivity is determined as the receiving sensitivity of the test. The frequency of the wireless radio frequency signal between the integrated tester and the terminal is the same as the frequency information in the control command, and the return error rate in the test process of the integrated tester is the same as the return error rate in the control command. Therefore, in the whole testing process, the industrial personal computer can adjust the testing parameters through the control command to determine the accuracy of the current test.

In the testing process, the integrated tester also needs to test the wireless radio frequency interference of the terminal under the non-scene to obtain a test reference value. That is, the comprehensive tester performs the test under the condition that the terminal is not in any of the above-mentioned scenes, and the same frequency, the same mode and the like are used (except that the terminal is not opened, other test variables are the same). In the process of testing different scenes, the comprehensive tester needs to test not only the receiving sensitivity in the scene, but also the receiving sensitivity of the terminal in the situation that the terminal is not in the scene (and is not in other scenes at the same time), so that the reference value can be tested when no interference occurs.

For example, when the current test scene is a bright screen scene, the receiving sensitivity of the radio frequency signal may be tested in the bright screen scene and the dark screen scene, respectively. The receiving sensitivity measured in the bright screen scene is a test result; the measured reception sensitivity in the dark screen scene is the reference value for the bright screen test described above. At this time, the dark screen scene is a reference scene of the bright screen scene, and during the reference test, except for the difference in scene, other variables are kept the same as the current test. It should be noted that the dark screen scene can also be used as a reference scene for other scene tests. For example, a reference scene that is a camera scene, a photo scene, or the like.

The responses after the information received by the comprehensive tester are different, and are respectively explained as follows:

and under the condition that the comprehensive tester receives the registration information, the comprehensive tester can start to register the terminal and start the test.

And under the condition that the comprehensive tester receives the test stopping instruction, the comprehensive tester can stop the current test.

Before the integrated tester performs testing, the terminal should already open its test scenario. I.e. steps S402, S403 and S404 are all before step S405. The following describes a possible implementation way for ensuring the terminal scene is turned on during the test process:

in a possible implementation manner, in the case that the terminal has finished executing step S403, the terminal may send scene confirmation information to the industrial personal computer. Correspondingly, the industrial personal computer receives the scene confirmation information from the terminal, and then the industrial personal computer may execute step S404.

After the industrial personal computer executes step S404, a start test instruction may be sent to the integrated tester. After the comprehensive tester receives a test starting instruction from the industrial personal computer, the comprehensive tester can start to execute the step S405, that is, the comprehensive tester can start to perform testing.

The above-described modes are illustrative and not restrictive.

S406, the comprehensive tester sends first test result information to the industrial personal computer.

In the testing process of the comprehensive tester, the testing result of each time can be recorded, and then first testing result information can be sent to the industrial personal computer. Correspondingly, the industrial personal computer can receive first test result information from the comprehensive tester. The test result information may include a reception sensitivity and a reference value of the reception sensitivity. The receiving sensitivity is a value of the receiving sensitivity of the radio frequency signal detected by the comprehensive tester under the condition that the terminal starts a certain test scene; the reference value of the receiving sensitivity is a value of the receiving sensitivity of the radio frequency signal detected by the integrated tester under the condition that the terminal does not start the test scenario and other test parameters are consistent with the test scenario (such as test frequency and the like).

Specifically, the integrated tester sends the obtained receiving sensitivity and the reference value of the receiving sensitivity to the industrial personal computer every time the integrated tester tests once.

S407, the industrial personal computer uploads second test result information to the cloud server.

After the industrial personal computer receives the first test result information from the comprehensive tester, the second test result information can be determined according to the first test result. That is, the industrial personal computer knows that the test is the reference value of the receiving sensitivity and the receiving sensitivity of the test of a certain frequency point in a certain scene, and then can determine the corresponding relation among the scene information, the frequency information, the receiving sensitivity and the reference value of the receiving sensitivity in the test. Accordingly, the second test information may include scene information, frequency information, reception sensitivity, and a reference value of the reception sensitivity. And then the industrial personal computer can send second test result information to the cloud server. Correspondingly, the cloud server can receive second test result information from the industrial personal computer.

And under the condition that the test task comprises a plurality of tests, the industrial personal computer can issue the control command for a plurality of times. The comprehensive testing instrument sequentially tests based on the control instruction to obtain a first test result, and the comprehensive testing instrument obtains the first test result once, so that the first test result once can be uploaded to the industrial personal computer, and the test result can be obtained through the test for multiple times.

For example, as shown in table 1, during the first test, the industrial personal computer may send a control command including 2550MHz and a game scenario to the integrated tester. The comprehensive tester can respectively test the receiving sensitivity of 2550MHz when a game scene is started and a game scene is not started based on the control instruction, and obtain the reference values of the receiving sensitivity and the receiving sensitivity of the test, so that first test result information can be obtained. And then the comprehensive tester can send first test result information to the industrial personal computer. In the process of the second test, the industrial personal computer can send control instructions including 2600MHz and game scenes to the comprehensive tester. The comprehensive tester can respectively test the receiving sensitivity of 2600MHz when starting a game scene and not starting the game scene based on the control instruction, and obtain the reference values of the receiving sensitivity and the receiving sensitivity of the test, thereby obtaining the first test result information. The integrated tester may then send first test result information … … to the industrial personal computer

TABLE 3

Test sequence	Testing frequency	Test scenario	Sensitivity of reception	Reference value of reception sensitivity
					1	2550MHz	Game scene	-107.6dBm	-109.2dBm
2	2600MHz	Game scene	-103.5dBm	-104.0dBm
					3	2650MHz	Game scene	-102.5dBm	-103.6dBm
4	2550MHz	Camera scene	-99.6dBm	-103.4dBm
					5	2600MHz	Camera scene	-102.7dBm	-102.6dBm
6	2650MHz	Camera scene	-105.4dBm	-106.5dBm

Table 3 exemplarily discloses a table of test result correspondence and test order of test frequency and test scenario. As shown in table 3, when all the tests in all the test tasks are completed, that is, after six tests, the industrial personal computer may receive the receiving sensitivity from the integrated tester and the reference value (first test result information) of the receiving sensitivity 6 times, and the industrial personal computer may correspondingly store the corresponding test result in table 3, and may determine table 3 as the second test result information. And then the industrial personal computer can send second test result information to the cloud server. The frequency information of the number of times is frequency information in each test.

And S408, the cloud server analyzes the interference test result based on the second test result information.

After the cloud server receives the second test result information from the industrial personal computer, the interference test result can be analyzed based on the second test result information. That is, whether the wireless radio frequency signal has interference may be determined based on the second test result, where the interference test result represents an interference situation of the wireless radio frequency signal in a corresponding scenario.

In the case that the second test result information includes the tested receiving sensitivity and the reference value thereof, the cloud server may determine whether the radio frequency signal is interfered based on a difference between the receiving sensitivity and the reference value of the receiving sensitivity and a set threshold. When the difference between the receiving sensitivity and the reference value of the receiving sensitivity is larger than a set threshold, the cloud server can determine that the wireless radio frequency signal has interference; otherwise, in the case where the difference between the reception sensitivity and the reference value of the reception sensitivity is not greater than (less than or equal to) the set threshold, there is no interference. The range of the set threshold may be 0dB to 10dB, and the values of the set threshold in each scene may be the same or different. It should be understood that, in the embodiment of the present application, the reference values of the receiving sensitivity and the receiving sensitivity are the values of the receiving sensitivity when the terminal starts a certain scene and does not start the scene, respectively, and therefore, under the same other conditions, when the receiving sensitivity detected by the integrated tester is far lower than the receiving sensitivity of the non-start scene under the condition of starting the scene, it may be determined that the terminal starts the scene to cause interference of the radio frequency signal.

Illustratively, in the case where the value of the reception sensitivity X is-107.5 dBm, the reference value a of the reception sensitivity is-103.5 dBm, and the threshold Δ is set to 8dB, | X-a | < Δ, it can be determined that there is no interference with the radio frequency signal.

After the cloud server determines the interference result, the interference test result may be displayed, and table 4 is an exemplary interference test result.

The 3 rd test scene is a shooting scene, the frequency is N78/10MHz and LTE3/10MHz, the networking mode is NSA mode, the measured receiving sensitivity is-108.6 Bm, the reference value is-105.2 dBm, and no interference exists in the interference result. The scenario of the 4 th test is a charging scenario, the frequency is N79/60MHz, the networking mode is an SA mode, the measured receive sensitivity is-105.5 dBm, the reference value is-103.5 dBm, and no interference exists as a result of the interference.

Therefore, the cloud server can define different scenes and determine whether the wireless radio frequency signal of the terminal is interfered or not in the different scenes. Therefore, the wireless radio frequency signals of the terminal can not be interfered in different use scenes, and the accuracy of the wireless radio frequency interference test of the terminal can be ensured. In the embodiment of the application, the radio frequency interference test standard of the terminal is more comprehensive and complete, the terminal meeting the radio frequency interference test standard (the terminal without interference is the detection result), and the performance of the terminal during communication can be better in different scenes, so that the communication experience of a user can be improved. In addition, the detection method in the embodiment of the application can perform the test only by sending the test task through the cloud server by the user, and the user does not need to adjust and operate the terminal device, so that the test process is simple, efficient and flexible.

In this application embodiment, the user can control various variables in the test process comprehensively through the high in the clouds server, does not need the user specifically to carry out corresponding operation to different industrial computers, comprehensive tester and terminal, and user's easy operation, efficiency of software testing also can improve.
