Description
Technical Field
The present invention relates to the field of device testing, and more particularly, to a method, a system, a device, and a medium for testing a communication device.
Background
With the development of 5G base station development technology, the base station products need to carry out verification test on radio frequency indexes of the base station in the stages of early debugging, acceptance test, production test and the like, and most of radio frequency index tests need to rely on a spectrum analyzer or a vector analyzer to demodulate signals sent by the base station, and acquire various parameters of the base station signals according to the requirements so as to carry out test and evaluation. However, the parameters that each spectrum analyzer or vector analyzer can test will vary depending on the licensed content of the spectrum analyzer or vector analyzer, for example, the vector magnitude error is the most important index among radio frequency indexes, the vector magnitude error can comprehensively measure the magnitude error and the phase error of the modulated signal, is the vector difference between the ideal error-free reference signal and the actual transmitted signal at a given moment, in mathematical terms, the vector magnitude error is the square root of the ratio of the average power of the error vector to the average power of the reference signal, and the measurement interval is a time slot expressed in terms of percentages. For the index of the vector amplitude error, only the vector analyzer can measure the vector amplitude error of the signal, and each vector analyzer can only be suitable for analyzing the specific type of signal, for example, the permission of most existing vector analyzers only allows the measurement of the vector amplitude error of the 4G signal, but cannot measure the 5G signal.
However, as the 5G technology is becoming popular, the requirement for testing the 5G base station is increasing, and since the vector amplitude error is the most important index in the radio frequency index, it is naturally required to incorporate the vector amplitude error into the test item, but the measurement of the vector amplitude error of the 5G signal is required to support the analysis of the 100MHz bandwidth signal. Therefore, most of the existing spectrum analyzers or vector analyzers are limited by permission, do not meet the signal analysis of 5G signals, meanwhile, the signal analysis and test with larger bandwidth have higher requirements on the performance of the instrument, the corresponding test cost is higher, and most of the spectrum analyzers or vector analyzers only supporting the signal analysis with smaller bandwidth can only be eliminated, so that the resource cannot be utilized better.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art, and provides a device testing method, a system, a device and a medium, which are used for solving the problems that the cost for developing a new analysis instrument is high and the utilization rate of the existing analysis instrument and resources is low because a novel signal modulated under a novel technical standard cannot be analyzed by using most of the existing spectrum analyzer or vector analyzer.
The invention adopts the technical scheme that:
a method of testing a communication device, comprising: generating more than one second signal according to the bandwidth of the first signal, inputting the generated more than one second signal into a tested communication device for processing, receiving the second signal processed by the tested communication device, demodulating and testing the second signal processed by the tested communication device according to a preset test instruction, generating more than one corresponding test data, and obtaining a test result of the tested communication device according to the test data; the first signal and the second signal are different in signal type, and the sum of bandwidths of the more than one second signals is equal to the bandwidth of the first signal; the predetermined test criteria are applicable to the first signal and the second signal.
As described in the background, if a specific test is to be performed on a communication device under test, a specific license needs to be held, and in particular, a test is performed on a communication device under test supporting specific signal processing, and an analysis license corresponding to a specific signal needs to be held. In the application scenario of the present invention, the default is that the permission of directly analyzing the first signal is not provided in the currently available analysis permission, but the permission of directly analyzing the second signal is provided, if the performance of the tested communication device for processing the first signal needs to be tested, more than one second signal with the total bandwidth equal to the first signal is input into the tested communication device for processing, and the sum of bandwidths of the signals processed by the tested communication device when processing more than one second signal is equal to the bandwidth of the first signal, so that the condition that the tested communication device continuously processes more than one second signal can indirectly explain the processing condition of one first signal. And receiving more than one second signal processed by the communication equipment to be tested, demodulating and testing the processed second signal according to a preset test instruction, generating more than one corresponding test data, combining a preset test standard and obtaining a test result. Since the preset test standard is applicable to the first signal and the second signal, that is, whether the test data of the first signal or the test data of the second signal, the test results need to be determined according to the test standard, the two signals share the same set of test standard, and since the total bandwidth of more than one second signal is equal to the bandwidth of the first signal, it can be determined that the test result of the tested communication device for processing more than one second signal is equal to the test result of the tested communication device for processing the first signal. The method provided by the invention utilizes the bandwidth of the first signal to generate more than one second signal to be input into the tested communication equipment for testing, can test under the condition of only holding the second signal analysis permission, does not need to acquire the first signal processing condition of the tested communication equipment, effectively utilizes the currently available permission resource, and does not need to add or utilize other temporarily unavailable new permissions.

Since the total bandwidth of the more than one second signals is equal to the total bandwidth of the first signals, the processing condition of the more than one second signals can be determined according to the processing condition of the more than one second signals by the tested communication equipment, so that when the test data generated by the second signals processed by the tested communication equipment are analyzed, when any one of the test data does not meet the preset test standard, the second signals corresponding to the test data do not meet the test standard, and since the total bandwidth of the more than one second signals is equal to the bandwidth of the first signals, if the test data of one of the second signals does not meet the test standard, the test data of the processed first signals do not meet the test standard, therefore, the tested communication equipment can be judged to have abnormality, and the reason of the abnormality needs to be analyzed; similarly, only when all the test data meet the preset test standard, the test data of the second signals processed by all the tested communication equipment meet the test standard, and when the tested communication equipment processes the first signals with the same bandwidth, the test data of the processed signals can reach the standard, and the tested communication equipment can be judged to be free from abnormality. And determining a test result by using a test standard applicable to both the first signal and the second signal, so that test data of a plurality of second signals processed by the tested communication equipment can indirectly indicate the processing condition of the tested communication equipment on the first signal.
Further, the test instruction comprises at least one test item executed on the second signal processed by the communication device under test; the test item includes a measurement of vector magnitude error.

Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the invention. For better illustration of the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Example 1
The embodiment provides a method for testing communication equipment, which comprises the following steps:
s1: generating more than one second signal according to the bandwidth of the first signal, and inputting the generated more than one second signal into a plurality of tested communication devices for processing;
specifically, the signal types of the first signal and the second signal are different, where the signal types are different, that is, signals modulated under different technical standards, for example, signals modulated under LTE (Long Term Evolution ) technical standards are 4G signals, and signal types of 5G signals modulated under 5G NR (New Radio, new air interface communication technology) technical standards are different; the sum of the bandwidths of the more than one second signal is equal to the bandwidth of the first signal.
In this embodiment, the communication device under test is any applicable communication device such as a base station, and the communication device under test supports processing the first signal and the second signal, where by default in this embodiment, there is no permission to directly analyze the first signal, but there is a permission to directly analyze the second signal, among the analysis permissions available at present. The sum of the bandwidths of more than one second signal is equal to the bandwidth of the first signal, meaning that the bandwidth of the first signal is greater than or equal to the bandwidth of a single second signal. The sum of bandwidths of the signals processed by the tested communication equipment when the tested communication equipment processes the more than one second signals is equal to the bandwidth of the one first signal, so that the situation that the tested communication equipment processes the more than one second signals can indirectly explain the processing situation of the one first signal.
Specifically, as shown in fig. 1, the specific implementation procedure of step S1 is as follows:
s11: judging whether the bandwidth of the first signal is within the bandwidth range of the second signal, if so, executing step S12; if not, executing step S13;
s12: for each first signal, generating a second signal according to the bandwidth of the first signal, and inputting the generated second signal into the communication equipment to be tested for processing;
s13: for each first signal, generating more than two second signals according to the bandwidth of the first signal, and inputting the generated more than two second signals into the communication equipment to be tested for processing;
in step S11, if the bandwidth of the first signal is within the bandwidth of the second signal, step S12 is performed: generating a second signal with the same bandwidth according to the bandwidth of the first signal, if the bandwidth of the first signal exceeds the bandwidth range of the second signal, executing step S13: generating more than two second signals according to the bandwidth of the first signals, enabling the total bandwidth of the more than two second signals to be equal to the bandwidth of the first signals, and inputting the more than two second signals into the tested communication equipment for processing. Preferably, the bandwidths of the two or more generated second signals are all the same.
Specifically, in step S12 or S13, before the second signal is input to the measured communication device, the frequency point and the power of the measured communication device may be configured in advance, and the power amplifier of the measured communication device may be controlled to be turned on.
S2: and receiving a second signal processed by the communication equipment to be tested, demodulating and testing the second signal according to a preset test instruction, generating more than one corresponding test data, and obtaining a test result according to the test data and a preset test standard.
In step S2, the test instruction and the test standard are preset, and the test instruction may be preset by the method implementer according to the actual situation. The test standard is a general or custom standard adopted corresponding to the content of the test instruction, and can be preset by a method implementer, but the preset test standard needs to be applicable to the first signal and the second signal, namely, whether the test data of the first signal or the test data of the second signal need to be determined according to the test standard, and the two signals share the same set of test standard. Step S2 is executed: testing more than one second signal processed by the tested communication equipment based on the permission of analyzing the second signal; the method specifically comprises the steps of receiving more than one second signal processed by the communication equipment to be tested, demodulating and testing the second signal processed by the communication equipment to be tested according to a preset test instruction, wherein the preset test instruction comprises a demodulation instruction and a specific test instruction, demodulation refers to a process of recovering a message from a modulated signal carrying information, testing the second signal based on the specific test instruction after demodulation, generating more than one corresponding test data, and combining with a preset test standard and obtaining a test result. Since the preset test criteria are applicable to the first signal and the second signal, and it is known from step S1 that the total bandwidth of the one or more second signals is equal to the bandwidth of the first signal, and thus the processing of the one or more second signals by the tested communication device is equivalent to the processing of the one or more first signals, it can be determined that the test result of the one or more second signals is also indirectly equal to the test result of the first signal. The method provided by the embodiment generates a plurality of second signals by utilizing the bandwidth of the first signals and inputs the second signals into the tested communication equipment for testing, and can test under the condition of only holding the second signal analysis permission without acquiring the first signal processing condition of the tested communication equipment, and effectively utilizes the currently available permission resources without adding new permissions.
Specifically, as shown in fig. 2, the execution process of step S2 is as follows:
s21: receiving a second signal processed by the communication equipment to be tested, demodulating and testing the second signal according to a preset test instruction, and generating more than one corresponding test data;
s22: judging whether the test data all meet the preset test standard, if any one test data does not meet the test standard, executing step S23; if all the test data meet the test standard, executing step S24;
s23: determining that the test result of the tested communication equipment is abnormal, and carrying out abnormality analysis on the tested communication equipment;
s24: determining that the test result of the tested communication equipment is that no abnormality exists;
executing step S21 to demodulate and test the second signal by using the test command, generating more than one test data corresponding to the second signal, and executing step S22: judging whether the test data accords with the preset test standard, because the total bandwidth of a plurality of second signals is equal to the total bandwidth of the first signals, the test condition of the first signals can be determined according to the test condition of the tested communication equipment on more than one second signals, therefore, when the test data generated by the second signals processed by the tested communication equipment are analyzed, the test standard applicable to the first signals is utilized for measuring, when any one of the test data does not accord with the test standard, the second signals corresponding to the test data do not accord with the test standard, and because the total bandwidth of more than one second signals is equal to the bandwidth of the first signals, if the test data of one of the second signals does not accord with the test standard, the test data of the processed first signals does not accord with the test standard, and the step S23 is executed: determining that the tested communication equipment has abnormality as a test result, and analyzing the cause of the abnormality; similarly, only if all the test data meet the preset test standard, the test data of the second signals processed by all the tested communication devices meet the test standard, and when the tested communication devices process the first signals with the same bandwidth, the test data of the processed signals can also reach the standard, and step S24 is executed: and determining that the tested communication equipment has no abnormality according to the test result. And determining a test result by using a test standard applicable to both the first signal and the second signal, so that test data of a plurality of second signals processed by the tested communication equipment can indirectly indicate the processing condition of the tested communication equipment on the first signal.
Specifically, in step S21, the test instruction includes at least one test item executed on the second signal processed by the tested communication device, where the test item includes measuring the vector magnitude error of the signal, and the preset test standard mentioned in step S22 includes a measurement standard value/range of the vector magnitude error, where the measurement standard value/range can represent the vector magnitude error of the normal signal processed by the tested communication device, and the standard value/range should be applicable to the first signal and the second signal.
The test instruction includes measurement of vector amplitude error of the signal, the vector amplitude error is an important index of the communication equipment test, the measurement of the vector amplitude error belongs to a specific test, a specific permission is required to be held, in addition, the types of the signals are limited in the permission, namely, the permission of the vector amplitude error measurement of different types of signals is different, as the analysis permission of the second signal is obtained in available resources by default, the permission of the vector amplitude error measurement of the second signal can be obtained, in the case of only holding the permission of the vector amplitude error measurement of the second signal, more than one second signal is generated by using the bandwidth of the first signal to be input into the communication equipment to be tested, and test data is compared with test standards, based on the former further scheme, the test standards are applicable to the evaluation judgment of the vector amplitude error of the first signal and the second signal, the test results of all the second signals obtained are equivalent to the test results of the corresponding first signal, and the permission of the first signal can be effectively utilized to test the available resources.
Specifically, the specific implementation procedure of step S23 is as follows: and determining that the test result of the tested communication equipment is abnormal, and acquiring and carrying out abnormality analysis on the tested communication equipment according to the log and the configuration information of the tested communication equipment. The log of the tested communication equipment records the whole processing process of the equipment, and the reasons that the indexes of the second signals cannot reach the standards after being processed by the tested communication equipment can be effectively analyzed by combining the configuration information, so that the abnormal reasons of the tested communication equipment can be further analyzed and obtained.
As shown in fig. 3, one of the preferred overall implementation procedures of the method provided in this embodiment is:
step S1 is executed: judging whether the bandwidth of the first signal is within the bandwidth range of the second signal, if so, executing step S12: for each first signal, generating a second signal according to the bandwidth of the first signal, and inputting the generated second signal into the communication equipment to be tested for processing; if not, execute step S13: for each first signal, generating more than two second signals according to the bandwidth of the first signal, and inputting the generated more than two second signals into the communication equipment to be tested for processing; step S21 is performed: demodulating and testing the second signal processed by the tested communication equipment according to a preset test instruction, and generating more than one corresponding test data; step S22 is performed: judging whether the test data accords with a preset test standard, if any one of the test data does not accord with the test standard, because the total bandwidth of more than one second signals is equal to the bandwidth of the first signals, if the test data of one of the second signals does not accord with the test standard, the test data of the processed first signals do not accord with the test standard when the tested communication equipment actually processes the first signals, and therefore, executing the step S23: determining that the test result of the tested communication equipment is abnormal, and acquiring and carrying out abnormal analysis on the tested communication equipment according to the log and the configuration information of the tested communication equipment; if all the test data meet the test standard, indicating that all the second signals meet the test standard, indirectly indicating that when the tested communication device processes the first signals with the same bandwidth, the test data of the processed signals can also reach the standard, and executing step S24: and determining that the test result of the tested communication equipment is that no abnormality exists.

Based on the same ideas of the above-described communication device testing method, the present embodiment also provides a communication device testing system that can be used to execute the above-described communication device testing method for testing the communication device under test 100.

The first signal is a 5G signal with a bandwidth within the bandwidth supported by the 5G base station for processing, and the second signal is a 4G signal or other general communication signal.
Since the existing available signal analysis permissions are mostly for 4G signals, the second signal is defined as a 4G signal in the illustration, and the 5G base station is tested based on the existing analysis permissions for 4G signals.

Specifically, the bandwidth value of the 5G signal corresponds to the number of generated 4G signals, and the bandwidth value of each generated 4G signal may refer to table 1. Referring to table 1, as an example, if the bandwidth of the 5G signal to be tested is 5MHz, step S12 is performed to generate a 4G signal of 5MHz instead of the 5G signal of 5MHz for further testing, and the bandwidth of the single 4G signal is the same as that of the single 5G signal.

Based on the assumption that the bandwidth of the 5G signal to be tested is 100MHz and the corresponding step S13, the 5G base station modulates and amplifies and outputs the received continuous 5 4G signals, and the vector analysis module 221 connected to the 5G base station receives the 5 second signals processed by the 5G base station, the vector analysis module 221 performs step S21: demodulating and testing the 5G signals processed by the 5G base station according to a preset test instruction, and generating 5 corresponding test data; step S22 is performed: judging whether the 5 pieces of test data meet the preset test standard, if any one piece of test data does not meet the test standard, executing step S23: judging that the 5G base station is abnormal, and acquiring and carrying out abnormality analysis on the 5G base station according to the log and the configuration information of the 5G base station; if all the 5 test data meet the test standard, step S24 is executed: and judging that the 5G base station is not abnormal.
Specifically, in step S21, the test instruction according to which the vector analysis module 221 includes a plurality of test items, where one test item is to measure a vector magnitude error of the signal, and preferably the test item further includes a downlink delay of the signal, a total power dynamic range (OFDM symbol power range), and/or a frequency error of the signal. In step S21, demodulation and vector magnitude error measurement are performed on the 5G 4G signals processed by the 5G base station according to a preset test command to obtain 5 test data, and step S22 is performed: judging whether the 5 test data meet the preset test standard, based on the 3GPP protocol, as shown in Table 2, the requirements on the vector amplitude errors of the 4G signal and the 5G signal are consistent, namely, the standard of the 3GPP protocol on the vector amplitude errors of the 4G signal can be used as the preset test standard, the standard is suitable for the 5G signal and the 4G signal, judging whether the 5 test data meet the corresponding standard, if any one test data does not meet the test standard, executing the step S23: judging that the 5G base station is abnormal, and acquiring and carrying out abnormality analysis on the 5G base station according to the log and the configuration information of the 5G base station; if all the 5 test data meet the test standard, step S24 is executed: and judging that the 5G base station is not abnormal. Therefore, based on the permission of analysis of the 4G signal available at present, particularly the permission of vector amplitude error measurement, the performance of the 5G base station for processing the 5G signal can be tested, various vector analyzers or vector analysis modules which are provided with permission for 4G signal analysis at present are effectively utilized, and the utilization rate of the instrument is maximized.
