Description

Technical Field

[0001] This invention relates to a method for testing the performance of communication equipment, and more particularly to a method for testing antenna balance and a method for troubleshooting unqualified system and field test indicators. Background Technology

[0002] Before being marketed, mobile phones and other communication devices typically undergo testing using methods such as turntable testing to evaluate the antenna's transmit and receive power and to measure its RF performance. One key performance indicator is antenna balance, which requires that the RSRP (Receiving Power Reduction) difference between different receiving antennas connected to the device under test within a single operating frequency band should not exceed a predetermined value. If the difference exceeds this value, the antenna is considered unbalanced, indicating a performance problem. However, when testing antenna balance, the test data is stored in test logs. After the logs are provided to R&D personnel, they must manually search through the logs to find relevant information, compile the average RSRP value for the test period, and perform a difference calculation on the average RSRP values ​​of different antennas. This analytical method is time-consuming and cannot quickly determine whether the antenna is balanced. Furthermore, for personnel unfamiliar with similar issues, searching for relevant information in the test logs requires even more time and is prone to missing information. Summary of the Invention

[0003] One of the objectives of this invention is to provide an antenna equalization detection method that can automatically determine whether the antenna equalization index meets the requirements based on test data.

[0004] To achieve the above objectives, the present invention provides an antenna equalization detection method, comprising the following steps:

[0005] Obtain the test logs of the field test of the communication device under test, and extract the RSRP test value of the communication device under test from the test logs;

[0006] The antenna balance of each operating frequency band of the communication device under test is determined based on the RSRP test value.

[0007] Furthermore, the test log includes antenna performance test data obtained through turntable testing during field testing.

[0008] Furthermore, during the turntable test, each receiving antenna connected to each working frequency band of the communication device under test is tested multiple times to obtain antenna performance test data for each receiving antenna connected to each working frequency band. The antenna performance test data includes RSRP test values.

[0009] Furthermore, during the turntable test, the communication device under test is tested in multiple test environments, and a cell is registered for each test environment, with the registered cell information stored in the test log.

[0010] In the step of extracting the RSRP test value of the communication device under test from the self-test log, the registered cell information is also extracted.

[0011] The step of determining whether the antenna equalization of each operating frequency band of the communication device under test is qualified based on the RSRP test value of the communication device under test also includes: determining whether the antenna equalization of each operating frequency band of the communication device under test is qualified in each registered cell.

[0012] Furthermore, the step of extracting the RSRP test value of the communication device under test from the self-test log includes the following sub-steps:

[0013] Identify the field in the test log used to record test information and use it as the target field.

[0014] Identify target fields in the test logs of the communication device under test;

[0015] Extract the RSRP test value and operating frequency band information of each antenna from the target field and record them.

[0016] Furthermore, the step of determining whether the antenna equalization of each operating frequency band of each communication device under test is qualified based on the RSRP test value includes the following sub-steps:

[0017] The RSRP test values ​​of each antenna under the same operating frequency band are extracted into a large frequency band category set, and the RSRP test values ​​of each antenna under the same large category are respectively formed into a small antenna category set;

[0018] Calculate the average RSRP test value in each antenna subclass set, and use it as the RSRP average value of that antenna subclass set to characterize the average RSRP value of that antenna in that operating frequency band;

[0019] Find the maximum and minimum values ​​of the RSRP average in each frequency band category set, and calculate the difference between the maximum and minimum values ​​as the antenna equalization difference for that frequency band category set;

[0020] The antenna equalization difference of the frequency band category set is compared with a pre-set equalization threshold. If the antenna equalization difference of the frequency band category set is less than the equalization threshold, it is determined that the antenna equalization of the communication device under test in the operating frequency band meets the requirements; otherwise, it is determined that the antenna equalization of the communication device under test in the operating frequency band does not meet the requirements.

[0021] Furthermore, the operating frequency band of the communication device under test includes an operating frequency band connected to dual receiving antennas and an operating frequency band connected to four receiving antennas; the preset equalization threshold includes a first equalization threshold and a second equalization threshold, the first equalization threshold is used as a criterion for judging whether the antenna equalization of the operating frequency band connected to dual receiving antennas meets the requirements, and the second equalization threshold is used as a criterion for judging whether the antenna equalization of the operating frequency band connected to four receiving antennas meets the requirements.

[0022] The step of comparing the antenna equalization difference of a frequency band category with a preset equalization threshold includes: determining whether the operating frequency band corresponding to the frequency band category is an operating frequency band connected to dual receiving antennas; if so, comparing the antenna equalization difference of the frequency band category with a first equalization threshold; otherwise, comparing the antenna equalization difference of the frequency band category with a second equalization threshold.

[0023] Another objective of this invention is to provide an antenna equalization detection system that can automatically determine whether the antenna equalization index meets the requirements based on test data.

[0024] To achieve the above objectives, the present invention provides an antenna equalization detection system, comprising:

[0025] The extraction module is used to acquire the test logs from the field tests of the communication device under test (DUT), and extract the RSRP test value and operating frequency band information of the DUT from the test logs; and

[0026] The equalization determination module determines whether the antenna equalization of each operating frequency band of each communication device under test is qualified based on the RSRP test value of each device under test.

[0027] Furthermore, the balance determination module includes:

[0028] The classification unit is used to extract the RSRP test values ​​of each antenna under the same operating frequency band into a frequency band category set, and to divide the RSRP test values ​​of each antenna under the same category into an antenna sub-category set.

[0029] The average value calculation unit is used to calculate the average value of the RSRP test values ​​in each antenna subclass set, which is used as the RSRP average value of that antenna subclass set;

[0030] The sorting unit is used to sort the RSRP average values ​​of each antenna subclass set under the same frequency band major class set, and obtain the maximum and minimum RSRP average values ​​under the major class set of that frequency band.

[0031] A threshold storage unit is used to store the default value of the balance threshold and a temporary value of the balance threshold input according to user needs. When a temporary value of the balance threshold is input, it is used as the balance threshold; otherwise, the default value of the balance threshold is used as the balance threshold.

[0032] The equalization judgment unit is used to calculate the difference between the maximum and minimum values ​​of the RSRP average value under the frequency band category set as the antenna equalization difference value, and compare it with the equalization threshold. If it is less than the equalization threshold, it is judged that the antenna equalization of the communication device under test in the operating frequency band meets the requirements; otherwise, it is judged that the antenna equalization of the communication device under test in the operating frequency band does not meet the requirements.

[0033] Another objective of this invention is to provide a method for troubleshooting unqualified field test indicators, which can quickly make a preliminary judgment on the cause of the fault based on test data.

[0034] To achieve the above objectives, the present invention provides a method for troubleshooting non-compliant field test indicators, comprising:

[0035] The antenna balance test method is used to determine whether the antenna balance of the communication device under test is qualified. If the antenna balance of the communication device under test is not qualified, the fault is determined to be in the antenna or radio frequency circuit of the communication device under test; otherwise, the fault is determined to be outside the antenna and radio frequency circuit of the communication device under test.

[0036] The antenna equalization detection method of the present invention has the following beneficial effects: by determining the target field, the test system can automatically extract relevant test data from the test log according to the target field, and then the antenna equalization can be automatically judged according to the judgment process determined in this embodiment, which solves the problem that manual judgment of antenna equalization is time-consuming and prone to errors.

[0042] The antenna equalization detection method, system, and field test index failure investigation method described in this invention will be further explained below with reference to the accompanying drawings and specific embodiments. However, this explanation does not constitute an improper limitation on the technical solution of this invention.

[0043] Please see Figure 1 , Figure 1 This is a flowchart of one embodiment of the antenna equalization detection method of the present invention. In this text, combined with… Figure 1 An illustrative example of an antenna equalization detection method is provided to illustrate the method more clearly. It should be understood that although the following will... Figure 1 The specific embodiment shown is described in detail as an example, but it is not intended to limit the scope of the antenna equalization detection method of the present invention to this specific embodiment. Apart from the steps that solve the necessary technical problems of the present invention, the other steps can be regarded as non-essential steps. These non-essential steps can be replaced by other steps with the same or similar functions in other embodiments, or these non-essential steps can be unnecessary in other embodiments.

[0044] Figure 1 In the illustrated embodiment, the antenna equalization detection method includes the following steps:

[0045] S1. Obtain the test log (i.e., Log) of the field test of the communication device under test (DUT), and extract the RSRP test value of the DUT from the test log. The test log includes antenna performance test data obtained through turntable testing during the field test. Turntable testing involves placing the test device (i.e., the DUT, such as a mobile phone under development) and the comparison device (i.e., a mature communication device, generally a commercially available mobile phone) on the same horizontally placed turntable. During the rotation of the turntable, the antenna and RF performance parameters of the test device and the comparison device are tested, ensuring that both the test device and the comparison device can receive signals from all directions. This allows for an accurate comparison of the antenna and RF performance of the test device and the comparison device. Since turntable testing is a commonly used testing method in the prior art, the specific process will not be elaborated here.

[0046] During turntable testing, each receiving antenna connected to each operating frequency band of the communication device under test is typically tested multiple times to obtain antenna performance test data for each receiving antenna connected to each operating frequency band. This antenna performance test data includes the RSRP test value. The operating frequency bands of communication devices are generally divided into operating frequency bands connected to dual receiving antennas (hereinafter referred to as 2RX operating frequency bands) and operating frequency bands connected to four receiving antennas (hereinafter referred to as 4RX operating frequency bands). For the 2RX operating frequency band, only the two receiving antennas connected to the communication device under test operating in this frequency band are tested; for the 4RX operating frequency band, all four receiving antennas of the communication device under test are tested.

[0047] Please see Figure 2 This step may specifically include the following sub-steps:

[0048] S110. Determine the field on the test log used to record test information (i.e., Log Key ID) and use it as the target field. Since the format of the test log is fixed, the field used to record test information such as RSRP test values ​​is also fixed. This field can be used as the target field so that the test system can automatically extract relevant test data from the test log based on the target field.

[0049] S120. Identify the target field on the test log of the communication device under test, so as to extract relevant information such as RSRP test value and operating frequency band from the target field.

[0050] S130. Extract the RSRP test value and operating frequency band information of each antenna from the target field and record them. Of course, when performing turntable testing, the communication device under test is usually tested in multiple test environments, and a cell is registered for each test environment. The registered cell information is stored in the test log. At this time, this step also extracts the registered cell information from the target field to facilitate subsequent calculations and judgments.

[0051] S2. Determine whether the antenna equalization of each operating frequency band of the communication device under test is qualified based on the RSRP test value. Please refer to [link / reference]. Figure 3 This step may specifically include the following sub-steps:

[0052] S210. Extract the RSRP test values ​​of each antenna under the same operating frequency band into a frequency band category set, and then divide the RSRP test values ​​of each antenna under the same category into a separate antenna category set. When there are multiple registered cells, the data is also classified based on each registered cell. First, the RSRP test values ​​of each registered cell are extracted separately, and then the RSRP test values ​​of each antenna under the same operating frequency band in each registered cell are divided into a frequency band category set.

[0053] S220. Calculate the average RSRP test value in each antenna subclass set, and use it as the average RSRP of that antenna subclass set, which represents the average RSRP of that antenna in the operating frequency band. That is, each antenna subclass set in each frequency band under each registered cell corresponds to an average RSRP.

[0054] S230. Sort the average RSRP values ​​in each frequency band category set from smallest to largest, find the maximum and minimum values ​​of the average RSRP values ​​in each frequency band category set, and calculate the difference between the maximum and minimum values ​​as the antenna equalization difference for that frequency band category set. That is, each frequency band category set under each registered cell corresponds to one antenna equalization difference.

[0055] S240. Compare the antenna equalization difference of the frequency band category set with a pre-set equalization threshold. If the antenna equalization difference of the frequency band category set is less than the equalization threshold, the antenna equalization of the communication device under test in the operating frequency band is deemed to meet the requirements; otherwise, the antenna equalization of the communication device under test in the operating frequency band is deemed to not meet the requirements. In this step, the judgment is performed on each frequency band category set under each registered cell, that is, the antenna equalization of each operating frequency band of the communication device under test is judged to be qualified in each registered cell.

[0056] Please see Figure 4 Since the operating frequency bands of the communication equipment under test are generally divided into 2RX and 4RX operating frequency bands, the pre-set equalization thresholds also include a first equalization threshold and a second equalization threshold. In this case, this step may include the following sub-steps:

[0057] S241. Pre-set a first equalization threshold and a second equalization threshold. The first equalization threshold is used as a criterion for judging whether the antenna equalization of the 2RX operating frequency band meets the requirements. For example, the first equalization threshold can be set to 5dB, then the antenna equalization difference of all 2RX operating frequency bands is compared with 5dB. The second equalization threshold is used as a criterion for judging whether the antenna equalization of the 4RX operating frequency band meets the requirements. For example, the second equalization threshold can be set to 7dB, then the antenna equalization difference of all 4RX operating frequency bands is compared with 7dB.

[0058] S242. Determine whether the operating frequency band corresponding to the current frequency band category is the 2RX operating frequency band; if so, execute step S243 to compare it with the first equalization threshold; otherwise, execute step S244.

[0059] S243. Compare the antenna equalization difference of the current frequency band category with the first equalization threshold. If the antenna equalization difference of the current frequency band category is less than 5dB (i.e. less than the first equalization threshold), it is determined that the antenna of the communication device under test is equal when it is working in this operating frequency band (i.e., the antenna equalization of the communication device under test in this operating frequency band meets the requirements); otherwise, it is determined that the antenna of the communication device under test is unbalanced when it is working in this operating frequency band (i.e., the antenna equalization of the communication device under test in this operating frequency band does not meet the requirements).

[0060] S244. Determine whether the operating frequency band corresponding to the current frequency band category is the 4RX operating frequency band; if so, execute step S245 to compare it with the second equalization threshold.

[0061] S245. Compare the antenna equalization difference of the current frequency band category with the second equalization threshold. If the antenna equalization difference of the current frequency band category is less than 7dB (i.e. less than the second equalization threshold), it is determined that the antenna of the communication device under test is equal when it is working in the operating frequency band; otherwise, it is determined that the antenna of the communication device under test is unbalanced when it is working in the operating frequency band.

[0062] In summary, the antenna equalization detection method of the present invention has the following beneficial effects: by determining the target field, the test system can automatically extract relevant test data from the test log based on the target field, and then automatically complete the judgment of antenna equalization according to the judgment process determined in this embodiment, which solves the problem that manual judgment of antenna equalization is time-consuming and prone to errors.

[0063] Please see Figure 5 , Figure 5 This is a structural block diagram of one embodiment of the antenna equalization detection system of the present invention. In this text, combined with… Figure 5 An illustrative example of an antenna equalization detection system is provided to illustrate the system more clearly. It should be understood that although the following will... Figure 5 The specific embodiment shown is described in detail as an example, but it is not intended to limit the scope of the antenna equalization detection system of the present invention to this specific embodiment. Apart from the structures that solve the necessary technical problems of the present invention (i.e., the extraction module 100 and the equalization determination module 200), the other structures can be regarded as non-essential structures. These non-essential structures can be replaced by other structures with the same or similar functions in other embodiments, or these non-essential structures can be unnecessary in other embodiments.

[0064] Figure 5In the illustrated embodiment, the antenna equalization detection system includes an extraction module 100 and an equalization determination module 200. The extraction module 100 acquires the test logs of the field test of the communication device under test (DUT), and extracts the RSRP test value and operating frequency band information of the DUT from the test logs. The extraction module 100 uses the fields on the test logs used to record test information as target fields. When extracting information, it first identifies the target fields from the test logs, and then extracts and records the RSRP test values ​​and operating frequency band information of each antenna from the target fields. Of course, if the test logs also store information about the registered cell, the extraction module 100 will also extract the registered cell information.

[0065] The equalization determination module 200 determines whether the antenna equalization of each operating frequency band of each communication device under test is qualified based on the RSRP test value of each device under test. The equalization determination module 200 may include a classification unit 210, an average value calculation unit 220, a sorting unit 230, a threshold storage unit 240, and an equalization judgment unit 250.

[0066] The classification unit 210 is used to extract the RSRP test values ​​of each antenna under the same operating frequency band into a set of major frequency band categories, and to divide the RSRP test values ​​of each antenna under the same major category into a set of minor antenna categories. Of course, if the information of registered cells is extracted, the classification unit 210 will first perform a first classification by registered cell, resulting in multiple registered cell categories. Then, under each registered cell category, a second classification will be performed by operating frequency band, forming multiple sets of major frequency band categories. Finally, under each major frequency band category of each registered cell category, a third classification will be performed by antenna, forming multiple sets of minor antenna categories.

[0067] The average value calculation unit 220 is used to calculate the average value of RSRP test values ​​in each antenna subclass set, as the RSRP average value of that antenna subclass set.

[0068] The sorting unit 230 is used to sort the RSRP average value of each antenna sub-category under the same frequency band major category set, so as to obtain the maximum and minimum RSRP average values ​​under the frequency band major category set.

[0069] The threshold storage unit 240 is used to store the default value of the balance threshold and the temporary value of the balance threshold input according to the user's needs. When a temporary value of the balance threshold is input, the temporary value of the balance threshold is used as the balance threshold and sent to the balance judgment unit 250. Otherwise, the default value of the balance threshold is used as the balance threshold and sent to the balance judgment unit 250.

[0070] The equalization judgment unit 250 is used to calculate the difference between the maximum and minimum values ​​of the RSRP average under each frequency band category set as the antenna equalization difference, and compare each antenna equalization difference with the corresponding equalization threshold. If it is less than the equalization threshold, it is determined that the antenna equalization of the communication device under test in the working frequency band meets the requirements; otherwise, it is determined that the antenna equalization of the communication device under test in the working frequency band does not meet the requirements.

[0071] Based on the above embodiments, the detection process of the antenna equalization detection system of the present invention is as follows:

[0072] First, determine whether the default equalization threshold values ​​for the 2RX and 4RX operating frequency bands stored in the threshold storage unit 240 should be used as the equalization threshold values ​​for the 2RX and 4RX operating frequency bands, respectively. If not, manually input the temporary equalization threshold value for the corresponding operating frequency band, and use the temporary equalization threshold value as the equalization threshold for that operating frequency band. For example, if the default equalization threshold value for the 2RX operating frequency band is deemed unsuitable, a temporary equalization threshold value for the 2RX operating frequency band can be manually input into the threshold storage unit 240. During the judgment, the temporary equalization threshold value for the 2RX operating frequency band will be used as the equalization threshold for the 2RX operating frequency band, instead of the default equalization threshold value for the 2RX operating frequency band.

[0073] For the 4RX operating frequency band, if the default value of the equalization threshold for the 4RX operating frequency band is deemed unsuitable, a temporary value for the equalization threshold can be entered. During the evaluation, this temporary value will be used as the final equalization threshold for the 4RX operating frequency band, rather than the default value. If only a temporary value for the equalization threshold for the 2RX operating frequency band is entered, and no temporary value for the 4RX operating frequency band is entered, the default value for the 4RX operating frequency band will still be used as the final equalization threshold.

[0074] After the turntable test is completed, the extraction module 100 obtains the test log of the field test of the communication device under test, and extracts the RSRP test value, operating frequency band information and registered cell information of the communication device under test from the test log. Then, the classification unit 210 classifies the registered cells to obtain multiple registered cell categories. Under each registered cell category, it classifies the operating frequency band to obtain multiple sets of major categories of each frequency band. Under each set of major categories of frequency bands, it classifies the antennas to obtain multiple sets of minor categories of antennas.

[0075] Then, the average value calculation unit 220 calculates the RSRP average value for each antenna sub-category set; then, the sorting unit 230 obtains the maximum and minimum RSRP average values ​​for each frequency band major category set by sorting; the equalization judgment unit 250 calculates the antenna equalization difference for each frequency band major category set and compares it with the equalization threshold, thereby determining whether the antenna equalization of the communication device under test meets the requirements in the working frequency band, and outputs the antenna equalization judgment result, so that the staff only needs to input the test log to directly obtain the antenna equalization judgment result.

[0076] In summary, the antenna equalization detection system of the present invention has the following beneficial effects:

[0077] The extraction module 100 can automatically extract relevant test data from the test log based on the target field. Then, the equalization judgment unit 250 can automatically complete the antenna equalization judgment. The required equalization threshold can also be re-entered as needed, which solves the problem that manual judgment of antenna equalization is time-consuming and prone to errors.

[0078] This invention also discloses a method for troubleshooting unqualified field test indicators. One embodiment of this method is used to make a preliminary judgment on the cause of a fault when a signal-related test indicator fails to meet the requirements during field testing of a communication device under test. The troubleshooting method includes: using the antenna equalization detection method of any of the above embodiments to determine whether the antenna equalization of the communication device under test is qualified; if the antenna equalization of the communication device under test is unqualified, the fault is determined to be in the antenna or radio frequency circuit of the communication device under test; otherwise, the fault is determined to be outside the antenna and radio frequency circuit of the communication device under test (e.g., other reasons such as the test environment).

[0079] In summary, the troubleshooting method for non-compliant field test indicators of the present invention has the following beneficial effects: when a signal-related test indicator fails to meet the requirements during the field test of the communication device under test, by first judging the antenna equalization, the range of possible causes of the fault can be narrowed down, and the approximate range of possible causes of the fault can be quickly determined, thereby effectively reducing the time required to determine the fault.

The equalization judgment unit is used to calculate the difference between the maximum and minimum values ​​of the RSRP average value under the frequency band category set as the antenna equalization difference value, and compare it with the equalization threshold. If it is less than the equalization threshold, it is judged that the antenna equalization of the communication device under test in the operating frequency band meets the requirements; otherwise, it is judged that the antenna equalization of the communication device under test in the operating frequency band does not meet the requirements.

10. A method for troubleshooting unqualified field test indicators, used to make a preliminary judgment on the cause of a fault when a signal-related test indicator fails to meet the requirements during field testing of a communication device under test, characterized in that, include: The antenna equalization detection method described in any one of claims 1 to 7 is used to determine whether the antenna equalization of the communication device under test is qualified. If the antenna equalization of the communication device under test is unqualified, the fault is determined to be in the antenna or radio frequency circuit of the communication device under test; otherwise, the fault is determined to be outside the antenna and radio frequency circuit of the communication device under test.
