It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

There is no such actual relationship or order between them. Furthermore, the term "comprises", "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus comprising a set of elements includes not only those elements, but also includes elements not expressly listed. other elements of or also include elements inherent in such a process, method, article, or device. Without further limitations, an element defined by the statement "comprising..." does not exclude the presence of additional same elements in the process, method, article or device comprising said element.

In order to ensure the reliability of the base station, it is necessary to regularly perform various tests on the base station. Among these tests, the test on the physical layer of the base station is more important. As shown in Fig. 1, the physical layer of the base station 100 is usually tested using a channel simulator 110, that is, each antenna 101 of the radio frequency unit 102 of the base station 100 is connected to the channel simulator 110 by using a radio frequency cable 120, and then the channel simulator 110 inputs the simulated radio frequency signals of each channel of the base station 100 to the radio frequency unit 102 through the radio frequency cable 120, and then the radio frequency unit 102 sends them to the baseband physical layer unit 103 and protocol stack unit 104 for physical layer testing.

However, for a base station with many channels, such as a 5G base station, the number of channels can reach as many as 256. When the above-mentioned scheme of using a channel simulator to test the physical layer of the base station is adopted, due to too many channels of the base station to be tested, the corresponding radio frequency There are also many antennas in the unit, and there are also many radio frequency cables that need to be connected to the antennas of the radio frequency unit. Therefore, a large number of testers are required to arrange.

In addition, the channel simulator used for testing also needs to support the same number of channels, and the more channels the channel simulator supports, the larger the instrument will be, which not only increases the cost of the channel simulator, but also requires more testers to make arrangements . Therefore, the above-mentioned solution of using the channel simulator to test the physical layer of the base station has a high test cost. In addition, the above-mentioned test based on the channel simulator needs to rely on radio frequency devices, and radio frequency devices are easily affected by external interference, and the test effect is also poor.

In order to solve the problems in the prior art, embodiments of the present application provide a method, device, equipment and storage medium for testing the physical layer of a base station. Firstly, the method for testing the physical layer of the base station provided by the embodiment of the present application will be introduced below.

On the other hand, the test equipment 210 can read the demodulation data uploaded by the baseband physical layer unit 201 from the analog protocol stack unit 202 pre-deployed in the base station under test 200, so as to generate the physical layer of the base station under test 200 based on the demodulation data. test results.

As shown in Figure 3, the method for testing the physical layer of the base station provided in the embodiment of the present application includes the following steps:

In an example embodiment, in addition to the radio frequency unit, the base station may also include a baseband physical layer unit and a protocol stack unit, and the baseband physical layer unit and the protocol stack unit together form the wireless interface protocol stack of the base station, wherein the baseband physical layer unit also Known as the physical layer, the protocol stack unit includes the data link layer and the network layer. During the operation of the base station, the data link layer and network layer located on the upper layer of the protocol stack can schedule data on the physical layer by configuring the physical layer parameters.

In order to achieve the purpose of testing the physical layer of the base station separately, and reduce the impact of the physical layer test on the base station, such as the problem of changing the data link layer and network layer related parameters caused by changing errors or forgetting to restore, this application is in the base station to be tested The analog protocol stack unit is deployed in the protocol stack to take over the corresponding functions of the data link layer and network layer in the upper layer of the protocol stack when performing base station physical layer testing, such as configuring physical layer parameters and receiving modulation data uploaded by the physical layer unit.

Specifically, before performing the base station physical layer test, the test equipment can generate test case parameters based on the specific requirements of the test cases of the base station to be tested, and then send the test case parameters to the simulated protocol stack unit of the base station to be tested.

S302. The simulated protocol stack unit configures preset physical layer parameters of the baseband physical layer unit based on the test case parameters, and sends the preset physical layer parameters to the baseband physical layer unit.

Afterwards, the analog protocol stack unit can send the preset physical layer parameters to the baseband physical layer unit.

S303. The test equipment converts the pre-acquired antenna data of the base station to be tested into CPRI data.

In an example embodiment, the tester may acquire antenna data of the base station under test in advance based on the specific requirements of the test case of the base station under test, and then input the acquired antenna data into the test device.

Specifically, the antenna data of the base station to be tested can be generated by simulation software, such as using the developed channel simulation software to generate antenna data according to the specific requirements of the test case; or, by means of the algorithm simulation completed in the base station design and development process program to generate antenna data according to the specific requirements of the test case. In addition, the antenna data of the base station to be tested may also be real antenna data collected at the radio frequency unit of the base station to be tested.

After receiving the antenna data of the base station to be tested, the test equipment can convert the antenna data of the base station to be tested into CPRI data, so as to directly input the test data to the baseband physical layer unit of the base station. Thus, the step of converting the antenna data into CPRI data by the radio frequency unit of the base station in the prior art, and then sending the CPRI data to the baseband physical layer unit is skipped, so that there is no need to use radio frequency cables and channel simulators to carry out the physical analysis of the base station. layer test, which greatly reduces the test cost of the physical layer of the base station.

It should be noted that the above-mentioned sequence of steps S301, S302, and S303 is just a description sequence, and is not the actual sequence of the various processes in steps S301, S302, and S303. , S302 before or after processing, or parallel processing with steps S301 and S302.

S304. The test equipment sends the CPRI data to the baseband physical layer unit of the base station to be tested.

In an exemplary embodiment, after the test equipment converts the antenna data of the base station to be tested into CPRI data, the CPRI data can be sent to the baseband physical layer unit of the base station to be tested, such as through a CPRI interface, or have a device for sending CPRI data other interfaces.

S305. The baseband physical layer unit demodulates the CPRI data based on preset physical layer parameters to generate demodulated data.

In an exemplary embodiment, after receiving the CPRI data, the baseband physical layer unit of the base station to be tested can demodulate the CPRI data based on the preset physical layer parameters configured by the analog protocol stack unit in step S302 above, to generate Demodulate the data.

S306. The baseband physical layer unit uploads the demodulated data to the analog protocol stack unit of the base station to be tested.

In an example embodiment, after the baseband physical layer unit of the base station to be tested generates demodulated data, it may upload the demodulated data to the analog protocol stack unit.

S307. The analog protocol stack unit forwards the demodulated data to the test equipment.

In an example embodiment, the simulated protocol stack unit of the base station to be tested may forward the demodulated data uploaded by the baseband physical layer unit to the test equipment. In this way, the test equipment can obtain the test results of the antenna data used for testing by the physical layer unit of the base station to be tested, thereby providing a data source for subsequent processing of generating test results.

S308. The test device generates a test result of the physical layer of the base station to be tested based on the demodulated data.

In an exemplary embodiment, after receiving the demodulated data forwarded by the analog protocol stack unit, the testing device may generate a test result of the physical layer of the base station to be tested based on the demodulated data.

Specifically, the test equipment can use the demodulation data corresponding to the preset physical layer parameters, that is, the verified demodulation data, to evaluate the test effect of the physical layer test of the base station. The testing device can match the demodulated data forwarded by the analog protocol stack unit with the demodulated data corresponding to the preset physical layer parameters. If the matching is successful, if the consistency of the matching exceeds a preset threshold, such as 95%, the testing device can generate a test result of passing the test; if they match, the testing device can generate a test result of failing the test.

Optionally, in order to ensure the synchronization between the test equipment and the base station under test and improve the accuracy of the physical layer test of the base station, the following processing may also be performed: clock synchronization with the base station under test is performed every preset period.

In an exemplary embodiment, considering that the physical layer unit of the base station under test operates in real time, the test equipment needs to input antenna data for testing into the physical layer unit of the base station under test in real time according to the scheduling of the base station under test. In order to achieve the above purpose, the test equipment may perform clock synchronization with the base station under test every preset period, such as 2000 milliseconds.

It is worth mentioning that the method for testing the physical layer of the base station provided by the embodiment of the present application can not only test the physical layer of the base station for 5G base stations with more channels, but also test the base station physical layer for base stations with fewer channels, such as 4G base stations and 3G base stations. Or 2G base station, conduct base station physical layer test.

In addition, the embodiments of the present application may be used in various application scenarios.

In the embodiment of the present application, automatic fast regression and continuous integration verification of 5G physical layer performance can also be performed. Due to the complexity of 5G scenarios, performance verification requires the establishment of a complex and huge test instrument networking environment, making automated testing very difficult. However, in the embodiment of the present application, the test device can even be a test board, which is easy to build, makes automatic control simple, and can realize continuous integration testing of physical layer performance.

In the embodiment of the present application, real antenna data can be collected in an external field environment, and then imported into testing equipment for testing, thereby realizing testing of real channel scenarios in a laboratory environment. In addition, when the external field problem is difficult to locate, the antenna data can be directly collected and imported into the test equipment to reproduce the problem, so that the problem can be quickly located in the laboratory.

This embodiment of the application can also be used for testing with a large number of users. Since the cost of the multi-user terminal simulator is relatively high, and there are few test environments with a large number of users in the laboratory, through the embodiment of the present application, the antenna data of the test environment with a large number of users can be collected, and then the physical layer test of the base station is performed, thereby It can realize the functional performance test of the physical layer of the base station in the scenario of a large number of users.

In the embodiment of the present application, by converting the antenna data of the base station to be tested into CPRI data, and then directly sending the CPRI data to the baseband physical layer unit of the base station to be tested, the radio frequency unit is skipped to first convert the antenna The step of converting the data into CPRI data and then sending the CPRI data to the baseband physical layer unit eliminates the need to use radio frequency cables and channel simulators, greatly reducing the test cost of the base station physical layer. Furthermore, since no radio frequency unit is used, the test environment is less affected by the outside world, which not only improves test accuracy, but also facilitates continuous integration and automated testing.

In addition, compared with the method of using a channel simulator to test the physical layer of the base station, this application can realize the verification of the physical layer performance of the base station in 5G complex scenarios without using complex and large test instruments, and can solve the problem of physical layer performance in large-scale antenna scenarios.
