It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. 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 merely intended to provide a better understanding of the present application by illustrating examples thereof.

Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of another like element in a process, method, article, or apparatus that comprises the element.
In order to ensure the reliability of the base station, various tests on the base station are required at regular time, and in the tests, the test on the physical layer of the base station is more important. As shown in fig. 1, a channel simulator 110 is generally used to test a physical layer of a base station 100, that is, each antenna 101 of a 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 a simulated radio frequency signal 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 the radio frequency signal to a baseband physical layer unit 103 and a protocol stack unit 104 to perform a physical layer test.
However, for a base station with many channels, for example, a 5G base station, the number of channels can reach as many as 256, and when the above scheme of using the channel simulator to test the physical layer of the base station is adopted, because the number of channels of the base station to be tested is too many, the number of antennas of the corresponding radio frequency unit is also many, and the number of radio frequency cables connected to the antennas of the radio frequency unit is also many, a large number of testers are required to arrange.
In addition, the channel simulator for testing also needs to support the same number of channels, and the more channels the channel simulator supports, the larger the instrument volume is, which not only increases the cost of the channel simulator, but also needs to add the testing personnel for arrangement. Therefore, the above-mentioned scheme of using the channel simulator to test the physical layer of the base station has a too high test cost. In addition, the above-mentioned test based on the channel simulator needs to rely on the radio frequency device, and the radio frequency device is easily affected by external interference, and the test effect is also relatively poor.
In order to solve the problem of the prior art, embodiments of the present application provide a method, an apparatus, a device, and a storage medium for testing a physical layer of a base station. First, a method for testing a physical layer of a base station provided in an embodiment of the present application is described below.
The main body of the test method of the physical layer of the base station may be a test device, such as a custom-designed test board, which may have a function of converting antenna data into CPRI (Common Public Radio Interface) data. As shown in fig. 2, on one hand, the test device 210 may convert the antenna data for the base station 200 to be tested into CPRI data, and directly send the converted CPRI data to the physical layer of the base station 200 to be tested, that is, the baseband physical layer unit 201. On the other hand, the test device 210 may 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 200 to be tested, so as to generate a test result of the physical layer of the base station 200 to be tested based on the demodulation data.
As shown in fig. 3, the method for testing the physical layer of the base station provided in the embodiment of the present application includes the following steps:
s301, the test equipment sends the test case parameters to the simulation protocol stack unit.
In an example embodiment, the base station may further include a baseband physical layer unit and a protocol stack unit, in addition to the radio frequency unit, and the baseband physical layer unit and the protocol stack unit together form a radio interface protocol stack of the base station, where the baseband physical layer unit is also referred to as a physical layer, and the protocol stack unit includes a data link layer and a network layer. In the operation process of the base station, the data link layer and the network layer which are positioned at the upper layer of the protocol stack can schedule data on the physical layer by configuring parameters of the physical layer.
In order to achieve the purpose of independently testing the physical layer of the base station and simultaneously reduce the influence of the physical layer test on the base station, such as the problem of error change or forgetting to recover caused by changing the relevant parameters of the data link layer and the network layer for many times, the method deploys a simulation protocol stack unit in the base station to be tested and is used for taking over the corresponding functions of the data link layer and the network layer on the upper layer of the protocol stack when the physical layer test of the base station is carried out, such as the functions of configuring the parameters of the physical layer and receiving the modulated data uploaded by the physical layer unit.
Specifically, before the physical layer test of the base station is performed, the test equipment may generate test case parameters based on specific requirements of a test case of the base station to be tested, and then send the test case parameters to the simulation protocol stack unit of the base station to be tested.
S302, the simulation 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.
In an example embodiment, after receiving the test case parameters, the analog protocol stack unit of the base station under test may configure the preset physical layer parameters of the baseband physical layer unit based on the test case parameters. The emulation protocol stack unit may then send the preset physical layer parameters to the baseband physical layer unit.
S303, the testing equipment converts the antenna data of the base station to be tested, which is acquired in advance, into common public radio interface CPRI data.
In an example embodiment, a tester may obtain antenna data of a base station to be tested in advance based on specific requirements of a test case of the base station to be tested, and then input the obtained antenna data to a test device.
Specifically, the antenna data of the base station to be tested may be generated by simulation software, for example, by using developed channel simulation software, the antenna data is generated according to the specific requirements of the test case; or generating antenna data according to the specific requirements of the test case by means of an algorithm simulation program finished in the base station design and development process. 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 achieve the purpose of directly inputting the test data into a baseband physical layer unit of the base station. Therefore, the step that in the prior art, the radio frequency unit of the base station converts the antenna data into CPRI data firstly and then sends the CPRI data to the baseband physical layer unit is skipped, so that the test of the physical layer of the base station is not required to be carried out by utilizing a radio frequency cable and a channel simulator, and the test cost of the physical layer of the base station is greatly reduced.
It should be noted that the sequence of steps S301, S302, and S303 is only a description sequence, and is not an actual sequence of the processing in steps S301, S302, and S303, and in an actual process, step S303 may be performed before or after steps S301 and S302, or may be performed in parallel with steps S301 and S302.
S304, the test equipment sends the CPRI data to a baseband physical layer unit of the base station to be tested.
In an example embodiment, after converting the antenna data of the base station to be tested into the CPRI data, the testing device may send the CPRI data to the baseband physical layer unit of the base station to be tested, for example, through a CPRI interface, or another interface configured to send the CPRI data.
S305, the baseband physical layer unit demodulates the CPRI data based on the 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 may perform demodulation processing on the CPRI data based on the preset physical layer parameter configured by the analog protocol stack unit in step S302, so as to generate demodulated data.
And S306, the baseband physical layer unit uploads the demodulation 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 under test generates the demodulated data, the demodulated data may be uploaded to the analog protocol stack unit.
S307, the simulation protocol stack unit forwards the demodulated data to the test equipment.
In an example embodiment, the analog protocol stack unit of the base station under test may forward the demodulated data uploaded by the baseband physical layer unit to the test equipment. Therefore, the test equipment can obtain the test result of the physical layer unit of the base station to be tested on the antenna data for test, thereby providing a data source for subsequent processing of generating the test result.
And S308, generating a test result of the physical layer of the base station to be tested by the test equipment based on the demodulation data.
In an example embodiment, after receiving the demodulated data forwarded by the analog protocol stack unit, the test device may generate a test result of a physical layer of the base station to be tested based on the demodulated data.
Specifically, the test device may evaluate the test effect of the physical layer test of the base station by using demodulation data corresponding to the preset physical layer parameter, that is, demodulation data that has been verified to be qualified. The test equipment may match the demodulated data forwarded by the analog protocol stack unit with the demodulated data corresponding to the preset physical layer parameter. If the matching is successful, if the matching consistency exceeds a preset threshold, if 95%, the test equipment can generate a test result which is qualified; if so, the test equipment may generate a test result that fails.
Optionally, in order to ensure the synchronization between the testing device and the tested base station and improve the accuracy of the physical layer test of the base station, the following processing may be performed: and performing clock synchronization with the base station to be detected every preset period.
In an exemplary embodiment, it is considered that the physical layer unit of the base station under test is operated in real time, so the test equipment needs to input the antenna data for test to the physical layer unit of the base station under test in real time according to the scheduling of the base station under test. To achieve the above object, the testing device may perform clock synchronization with the base station to be tested every preset period, for example, 2000 ms.
It is worth mentioning that the method for testing the physical layer of the base station provided in the embodiment of the present application may perform the physical layer test of the base station not only on the 5G base station with more channels, but also on the base station with less channels, such as the 4G base station, the 3G base station, or the 2G base station.
In addition, the embodiment of the application can be used for various application scenarios.
Specifically, in the embodiment of the application, the performance of the physical layer of the 5G base station in a complex channel environment can be independently verified, especially the performance of the physical layer in a large-scale antenna scene, including but not limited to verifying the functions and performances of each channel demodulation algorithm, measurement algorithm and characteristic algorithm of the physical layer.
According to the embodiment of the application, automatic fast regression and continuous integrated verification of the 5G physical layer performance can be performed. Due to the complexity of the 5G scene, a complex and huge test instrument networking environment needs to be established for performance verification, so that the automatic test is very difficult. In the embodiment of the application, the test equipment can even be a test board, the building is simple, the automation control becomes simple, and the continuous integrated test of the physical layer performance can be realized.
According to the embodiment of the application, the simulation test of the outfield real environment and the positioning function of complex problems can be realized. According to the embodiment of the application, the real antenna data can be acquired in the external field environment and then introduced into the test equipment for testing, so that the real channel scene can be tested in the laboratory environment. In addition, when the outfield problem is difficult to locate, the antenna data can be directly collected and imported into the testing equipment to reproduce the problem, so that the problem can be quickly located in a laboratory.
The embodiment of the application can also be used for testing a large number of users. Due to the fact that the cost of the multi-user terminal simulator is high, and the testing environment for large user amount in a laboratory is small, antenna data of the testing environment for large user amount can be collected through the embodiment of the application, and then the physical layer of the base station is tested, and therefore functional performance testing of the physical layer of the base station under the scene of large user amount can be achieved.
In the embodiment of the application, the antenna data of the base station to be tested is converted into the common public radio interface CPRI data, and then the CPRI data is directly sent to the baseband physical layer unit of the base station to be tested, so that the steps of firstly converting the antenna data into the CPRI data by the radio frequency unit and then sending the CPRI data to the baseband physical layer unit are skipped, a radio frequency cable and a channel simulator are not needed, and the test cost of the base station physical layer is greatly reduced. Furthermore, because the radio frequency unit is not used, the test environment is slightly influenced by the outside, the test accuracy can be improved, and the continuous integrated automatic test is facilitated.
In addition, compared with a method for testing the physical layer of the base station by adopting a channel simulator, the method can realize the verification of the physical layer performance of the base station under a 5G complex scene without using a complex and huge testing instrument, and can solve the problem of difficult performance testing of the physical layer of a large-scale antenna scene.
