Detailed Description

Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of a suitable scenario of an embodiment of the present application. As shown in FIG. 1, the test computer may be connected to the test instrument through a General-purpose interface bus (General-Purpose Interface Bus, GPIB) or a network port, etc., so as to control the test instrument. The tested equipment and the measuring antenna are arranged in the shielding box, the measuring antenna can be connected with the testing instrument through a radio frequency Cable (RF Cable), and the measuring antenna and the tested equipment send or receive waveform files in an OTA mode, so that communication between the testing instrument and the tested equipment is established.

In the embodiment of the application, the test instrument is used for performing OTA test on the tested device based on the control of the test computer, for example, testing test signals of the tested device in various modes (such as 2G, 3G, 4G, 5G, wiFi, bluetooth and the like). The device under test may be any terminal device having wireless communication functions, such as a cell phone, tablet, personal computer, etc. The test computer can be an industrial personal computer, a computer and other equipment. The shielding cage may be used to shield interfering signals around the device under test. The measurement antenna may be used to send or receive test signals, feedback information, and other various information needed during OTA testing in the form of a waveform file.

As an example, the test instrument transmits a waveform file containing the test signal to the measurement antenna via a radio frequency cable. The measurement antenna then broadcasts the waveform file in the mask. After receiving the waveform file, the tested device demodulates the waveform file to obtain a test signal.

Fig. 2 is a schematic diagram of a scenario of a conventional air interface testing method. As shown in fig. 2, the test computer and the tested device generally communicate directly through a wired connection or a wireless connection, and the test computer can directly send a control instruction to the tested device. After the tested device performs signal measurement to obtain a test result, the tested device can also directly send the test result to the test computer. The air interface test mode is simple and quick. However, whether a wired connection mode or a wireless connection mode is adopted between the test computer and the tested equipment, the air interface test may be interfered, and the accuracy of the air interface test result is affected.

In view of this, in the embodiment of the present application, the test instrument generates and transmits the first waveform file to the device under test, where the first waveform file includes the target instruction information. After receiving the first waveform file, the tested equipment demodulates the first waveform file, reads out target instruction information and executes related operation in the air interface test process, and after the operation is finished, feedback information is sent to the test instrument. And finally, determining a target test result by the test instrument according to the feedback information, and completing the air interface test. Therefore, the tested equipment does not need to establish wired connection or wireless connection with the test computer, and the interference problem caused by wired communication or wireless communication is not needed to be considered, and the target instruction information is transmitted to the tested equipment in the form of a waveform file by using the test instrument, so that the control of the tested equipment is realized, and the accuracy of an air interface test result is improved.

Referring to fig. 3, a flow diagram of an air interface testing method according to an embodiment of the present application is shown. The steps shown in fig. 3 are described below.

In step 301, the test instrument generates a first waveform file containing target instruction information.

It should be noted that, the target instruction information may be acquired by the test computer and issued to the test instrument, and the test computer may acquire the target instruction information by detecting the instruction of the tester. The specific content and form of the target instruction information can be customized according to the tested items and the requirements of the tested equipment. Because the target instruction information in the traditional technical scheme is directly issued to the test instrument by the test computer, a new interaction protocol between the test computer and the test instrument is added before the air interface test is carried out, and the new interaction protocol is used for transmitting the target instruction information to the test instrument by the test computer.

In the embodiment of the application, the test instrument needs to add a waveform file real-time generation function of target instruction information, wherein the waveform file is a file containing relevant signal characteristics, is usually stored in a digital format, describes the time domain and frequency domain characteristics of the signal, and can be used for simulating, generating or playing back specific wireless signals. After the testing instrument acquires the target instruction information, the first waveform file is generated by utilizing the waveform file real-time generation function.

In the embodiment of the application, two test scenes exist in the air interface test, one is that the tested equipment sends a test signal, and the test instrument measures (hereinafter referred to as scene one); the other is that the test instrument sends a test signal and the device under test measures (hereinafter referred to as scenario two).

Specifically, the target instruction information corresponding to the two test scenes is different, the target instruction information corresponding to one of the two test scenes is equipment instruction information, the equipment instruction information is used for performing radio frequency control on the tested equipment, such as mode switching, channel switching, signal emission power adjustment and the like, after the tested equipment is switched or adjusted, a test signal (which is defined as a preset equipment signal in the embodiment of the application) is sent, and the subsequent tested equipment measures the preset equipment signal. The target instruction information corresponding to the second scenario is test instruction information, where the test instruction information is used to instruct the tested device to measure a test signal (which is defined as a preset instrument signal in the embodiment of the present application) sent by the test instrument. Therefore, by issuing different target instruction information aiming at two different test scenes and indicating the tested equipment to execute corresponding operation, the flexibility of the air interface test method is improved.

In step 302, the test instrument broadcasts a first waveform file.

As an example, the test instrument may broadcast a first waveform file containing target instruction information within the shielded enclosure via the measurement antenna so that the device under test, which is also within the shielded enclosure, may receive the target instruction information and perform subsequent operations.

In step 303, the device under test receives and demodulates the first waveform file broadcast by the test instrument, and determines the target instruction information.

In the whole testing process, the tested equipment is in an online receiving state in real time, and after the tested equipment receives a first waveform file broadcast by a testing instrument, the first waveform file is demodulated, and target instruction information is read.

In the embodiment of the application, the target instruction information can be embedded in the waveform file in a specific data format.

As an example, assuming the data format is digital, different target instruction information may be represented by different numbers, assuming 000001 to indicate that the device under test switches the model to 5G. Then when the device under test receives the first waveform file, the demodulated number is 000001, and the device under test performs an operation of switching the model to 5G.

And step 304, the tested equipment generates feedback information according to the target instruction information.

The feedback information is preset equipment signals corresponding to the target instruction information or test result information generated according to the target instruction information.

When the test scene is a scene one, the target instruction information is equipment instruction information, and after the tested equipment executes corresponding operation according to the equipment instruction information, a preset equipment signal under parameters such as a specific mode, a specific channel, specific signal transmitting power and the like is obtained, wherein the preset equipment signal is feedback information which needs to be sent to a test instrument by the tested equipment under the scene.

When the test scene is a scene two, the target instruction information is test instruction information, and the test instruction information is used for indicating the tested equipment to test. Before that, the test instrument needs to send a preset instrument signal, which is similar to the preset equipment signal and is also a test signal under parameters such as a specific mode, a specific channel, a specific signal transmitting power and the like. After receiving the preset instrument signal, the tested equipment performs testing based on the preset instrument signal to generate test result information, and finally, the test result information is used as feedback information to be sent to the testing instrument.

In addition, because the test instrument and the tested device are communicated in the form of waveform files in the air interface test process, the process of determining the test result information by the tested device in the second scenario can be specifically as follows: the testing instrument acquires a third waveform file containing a preset instrument signal, then broadcasts the third waveform file, and the tested equipment determines testing result information according to the third waveform file after receiving the third waveform file.

The third waveform file may be generated and issued by the test computer, or may be a preset instrument signal generated by the test computer, and the test instrument generates the third waveform file based on the preset instrument signal.

In one possible implementation manner, the tested device may obtain the actual measurement instrument signal by measuring the preset instrument signal, and then generate the test result information according to the actual measurement instrument signal and the preset instrument signal. That is, the tested device receives and demodulates the third waveform file after receiving the third waveform file, determines the actual measurement instrument signal, and then generates test result information according to the actual measurement instrument signal and the preset instrument signal.

Further, whether the actually measured instrument signal is matched with the preset instrument signal can be judged by comparing whether one or more signal indexes (such as signal transmitting power and the like) of the actually measured instrument signal and the preset instrument signal are consistent or whether an error is within a preset range. If the signal indexes are consistent or the error is within a preset range, the actually measured instrument signal is considered to be matched with the preset instrument signal, and the test result information is that the test is passed; if the signal indexes are inconsistent or the errors are not in the preset range, the measured instrument signals are not matched with the preset instrument signals, and the test result information is that the test fails. In one possible implementation manner of the embodiment of the present application, the test result information includes that the test passes or fails, and the tested device generates the test result information according to the actually measured instrument signal and the preset instrument signal, including: when the actually measured instrument signal is matched with the preset instrument signal, determining that the test result information is the passing of the test; and when the actually measured instrument signal is not matched with the preset instrument signal, determining that the test result information is that the test fails.

In step 305, the device under test sends feedback information to the test instrument.

It should be understood that when the test scene is a scene one, the device under test sends a preset device signal to the test instrument; and when the test scene is the second scene, the tested equipment sends the test result information to the test instrument.

The preset device signal and the test result information are required to be sent to the test instrument in the form of waveform files, similar to the actual measurement instrument signal.

Namely, as a possible implementation manner of the embodiment of the present application, the device under test sends a preset device signal to a testing instrument, including: the tested equipment generates a second waveform file containing a preset equipment signal; and the tested device broadcasts the second waveform file.

As another possible implementation manner of the embodiment of the present application, the sending, by the device under test, test result information to the test apparatus includes: the tested equipment generates a fourth waveform file containing the test result information, and broadcasts the fourth waveform file.

Step 306, the test instrument determines a target test result according to the feedback information.

And when the test scene is one, the test instrument measures the received preset equipment signal, and finally a target test result is generated.

In one possible implementation, the test instrument receives and demodulates the second waveform file broadcast by the device under test, determines the measured device signal, and then generates the target test result according to the measured device signal and the preset device signal.

Further, whether the measured device signal is matched with the preset device signal can be determined by comparing whether one or more signal indexes (such as signal transmission power) of the measured device signal and the preset device signal are consistent or whether an error is within a preset range. If the signal indexes are consistent or the errors are within a preset range, the actual measurement equipment signals are considered to be matched with the preset equipment signals, and the target test result is that the test is passed; if the signal indexes are inconsistent or the errors are not in the preset range, the actual measurement equipment signals are not matched with the preset equipment signals, and the target test result is that the test fails. In one possible implementation manner of the embodiment of the present application, the target test result includes that the test passes or fails, and the test instrument generates the target test result according to the measured device signal and the preset device signal, including: when the actually measured equipment signal is matched with the preset equipment signal, the testing instrument determines that the target testing result is the passing of the test; or when the measured device signal is not matched with the preset device signal, the test instrument determines that the target test result is that the test fails.

When the test scene is a scene two, the test instrument receives and demodulates a fourth waveform file broadcast by the tested equipment, determines test result information, and further directly determines the test result information as a target test result.

It can be understood that when the test scene is a scene one, the target test result is generated by the test instrument; and when the test scene is a scene two, generating a target test result through the tested equipment.

According to the air interface testing method provided by the embodiment of the application, the first waveform file is generated and issued to the tested equipment through the testing instrument, and the first waveform file contains target instruction information. After receiving the first waveform file, the tested equipment demodulates the first waveform file, reads out target instruction information and executes related operation in the air interface test process, and after the operation is finished, feedback information is sent to the test instrument. And finally, determining a target test result by the test instrument according to the feedback information, and completing the air interface test. Therefore, the tested equipment does not need to establish wired connection or wireless connection with the test computer, and the interference problem caused by wired communication or wireless communication is not needed to be considered, and the target instruction information is transmitted to the tested equipment in the form of a waveform file by using the test instrument, so that the control of the tested equipment is realized, and the accuracy of an air interface test result is improved.

Fig. 4 is a flow chart of a scene one-based air interface test method according to an embodiment of the application. Fig. 4 can be seen as an example of steps 301 to 306. As shown in fig. 4, the test computer acquires instruction information and judges, if the instruction information is the instruction information of the test instrument, the test instrument prepares the test condition, and the test is ready to start; if the device instruction information is the device instruction information, the test instrument generates a first waveform file containing the device instruction information and broadcasts the first waveform file. The tested device is in a real-time receiving state, after receiving the first waveform file, the tested device demodulates the first waveform file to obtain device instruction information, then executes the device instruction information (for example, the tested device switches 4G to 5G, then switches a channel to a certain channel of 5G, finally adjusts the signal transmitting power to the target power), and after executing the device instruction information, determines a preset device signal. And then the tested device generates a second waveform file containing the preset device signal, and further broadcasts the second waveform file. And the testing instrument receives and demodulates the second waveform file broadcasted by the tested equipment, determines the actual measurement equipment signal, and finally generates testing result information and reports the testing result information to the testing computer according to the actual measurement equipment signal and the preset equipment signal.

Fig. 5 is a flow chart of a scene two-based air interface testing method according to an embodiment of the application. Fig. 5 can be seen as an example of steps 301 to 306. As shown in fig. 5, the test instrument obtains a third waveform file containing the preset instrument signal, and the test instrument generates the third waveform file based on the preset instrument signal. The test instrument broadcasts the third waveform file. The tested equipment receives and demodulates the third waveform file broadcasted by the testing instrument to determine the signal of the actually measured instrument. And the tested equipment generates test result information according to the actually measured instrument signal and the preset instrument signal. And finally, the tested equipment generates and broadcasts a fourth waveform file containing the test result information, and the test instrument demodulates the fourth waveform file to obtain the test result information and uploads the test result information to the test computer.

The method of the embodiment of the present application is mainly described above with reference to the drawings.
