[0066] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0068] like Figure 1 The diagram shown is a flowchart illustrating a method for determining target test points according to an embodiment of this application, including the following steps.

[0069] S101: Send a test signal to the test space where the device under test is located.

[0070] The device under test (DUT) includes communication devices with antenna communication capabilities, such as mobile phones and tablets. For the test space, in order to obtain the signal reception data of the DUT within the test space, the test space needs to cover the test signal. The frequency band of the test signal can be determined based on the test mode set by the tester.

[0071] It should be noted that the test space where the device under test is located can be determined based on the spatial movement range of the device under test. By mounting the device under test on the movable platform of the multi-axis linkage device, the spatial movement function of the multi-axis linkage device can be used to control the spatial movement of the device under test.

[0072] In some examples, the multi-axis linkage device can be a three-axis linkage device, which enables the device under test to move in at least three-dimensional spatial directions.

[0073] In some examples, to ensure the test space covers the test signal, the test signal transmitting device, such as an antenna coupling plate, can be mounted on the multi-axis linkage device. In one possible implementation, the antenna coupling plate can be mounted above the test space provided by the multi-axis linkage device for the device under test. To ensure the test signal is not affected by external interference, a shielding box can be set above the test space, the antenna coupling plate can be placed in the shielding box, and the antenna coupling plate can be connected to the test instrument through a power divider. The test instrument is placed outside the shielding box.

[0074] In some examples, different test signals correspond to different test modes, and different test modes correspond to different frequency bands in different antenna systems. In other words, multiple frequency bands under any antenna system correspond one-to-one with a test mode.

[0075] In one possible implementation, when the test mode is the first mode, the transmitted test signal is the first test signal, which corresponds to a certain frequency band in a certain antenna system.

[0076] In some examples, the signaling tests involve frequency bands including GSM, WCDMA, CDMA, and LTE. GSM includes 4 frequency bands, WCDMA includes 5 frequency bands, CDMA includes 3 frequency bands, and LTE includes 20 frequency bands.

[0077] In some examples, due to the large number of frequency bands and the commonalities among some of them, the frequency bands can be reclassified based on these commonalities to obtain low-frequency bands, mid-frequency bands, and high-frequency bands. In one possible implementation, the low-frequency band is less than 1 GHz, the mid-frequency band is in the range of 1 GHz to 2 GHz, and the high-frequency band is greater than 2 GHz. Furthermore, a representative low-frequency band (e.g., GSM900) can be selected from the frequency bands included in the low-frequency band, a representative mid-frequency band (e.g., WCDMA1700) can be selected from the frequency bands included in the mid-frequency band, and a representative high-frequency band (e.g., LTEB7) can be selected from the frequency bands included in the high-frequency band.

[0078] In one possible implementation, the test mode includes at least a first mode, a second mode, and a third mode, wherein the first mode corresponds to transmitting a first test signal, the frequency band corresponding to the first test signal being a low-frequency band (e.g., GSM900), the second mode corresponds to transmitting a second test signal, the frequency band corresponding to the second test signal being a mid-frequency band (e.g., WCDMA1700), and the third mode corresponds to transmitting a third test signal, the frequency band corresponding to the third test signal being a high-frequency band (e.g., LTEB7).

[0079] S102: Obtain signal reception data of the device under test at multiple test points.

[0080] Among them, multiple test points are located within the test space.

[0081] In some examples, the signal reception data of the device under test at the test point includes the signal strength received by the device under test at that test point.

[0082] In some examples, a multi-axis linkage device can be used to control the device under test to move to multiple test points in order to obtain the signal strength received by the device under test at multiple test points.

[0083] In some examples, the number and distribution of multiple test points can be set by technicians according to the actual situation. In one possible implementation, there can be 13 test points, and the distribution of the 13 test points can be found in [reference needed]. Figure 2 As shown, the 13 test points can be located on the same plane. In another possible implementation, there can be 11 test points, and the distribution of the 11 test points is shown in [reference needed]. Figure 3 As shown, the 11 test points are not all on the same plane.

[0084] In some examples, multiple test points can also be obtained from other test sites via the Internet. That is, multiple test point samples obtained when performing the same type of test task as the device under test using other test sites can serve as test points for the device under test. In one possible implementation, some test point samples can be selected from multiple test point samples provided by other test sites to serve as test points for the device under test, thereby improving the reliability of test point selection.

[0085] S103: Determine the target test point based on the received signal data.

[0086] Among them, the signal reception data of the device under test at the target test point meets the target conditions.

[0087] In some examples, the signal reception data includes signal strength. Accordingly, a target test point can be determined based on the signal strength received by the device under test at multiple test points. The signal strength corresponding to the target test point is the highest among all test points in the test space.

[0088] In some examples, the test point with the highest signal strength can be selected from multiple test points as the target test point.

[0089] In some examples, if the number of multiple test points is small, the target test point selected directly from these points may not be the one with the highest signal strength among all test points in the test space. Therefore, it is necessary to search other test points in the test space to further determine the target test point. To narrow down the search range for the target test point, multiple test points can be used to locate the area within the test space where the target test point is located. By searching all test points within this area, the target test point can be obtained, thus effectively improving the search efficiency.

[0090] Optionally, the specific implementation process of determining the target test point based on the signal reception data may include: determining a pre-selected area based on the signal reception data of the device under test at multiple test points; and determining the target test point based on the pre-selected area.

[0091] Understandably, by determining a pre-selected area based on the signal reception data corresponding to multiple test points, it can generally be determined that the target test point is located in the pre-selected area, thereby narrowing the range of searching for the target test point in the test space, avoiding wasting time searching other areas, and effectively improving the search efficiency of the target test point.

[0092] Optionally, the specific implementation process of determining the pre-selected area based on the signal reception data of the device under test at multiple test points may include: determining key points from the multiple test points based on the signal reception data of the device under test at multiple test points; and determining the pre-selected area based on the key points.

[0093] In some examples, the key points identified from multiple test points may include a first point, a second point, and a third point. The first, second, and third points can be the three test points with the highest signal strength among the multiple test points.

[0094] In one possible implementation, after obtaining the signal strength received by the device under test at multiple test points, the multiple test points are sorted in descending order of signal strength to obtain a test point sequence. Then, the first test point in the test point sequence is selected as the first point, the second test point in the test point sequence is selected as the second point, and the third test point in the test point sequence is selected as the third point.

[0095] Optionally, the specific implementation process of determining the pre-selected area based on key points may include: determining at least two first areas based on key points; and taking the intersection of at least two first areas as the pre-selected area.

[0096] In one possible implementation, such as Figure 2 As shown, the key points identified from multiple test points include point 1, point 2, and point 3, where point 1, point 2, and point 3 are located on the same plane (e.g., Figure 2(As shown in the XY plane), the signal strength at point 1 is higher than that at point 2, and the signal strength at point 2 is higher than that at point 3. Based on points 1 and 2, a first region A can be determined, which includes a circular region with the shortest distance between points 1 and 2 as its diameter. Based on points 1 and 3, a first region B can be determined, which also includes a circular region with the shortest distance between points 1 and 3 as its diameter. Based on the intersection of the first regions A and B, the intersection is as follows: Figure 2 The target area E shown is used as a pre-selected area, which is a planar area.

[0097] In some examples, if there are n key points and the n key points are on the same plane, the key point with the highest signal strength among the n key points can be selected as the target point. Based on the shortest distance between the target point and other key points as the diameter, a first region with n-1 circular regions is constructed. The intersection of the n-1 first regions is used as the pre-selected region.

[0098] In one possible implementation, such as Figure 3 As shown, the key points identified from multiple test points include point 1, point 2, and point 3. Points 1, 2, and 3 are located on different planes. The signal strength corresponding to point 1 is higher than that corresponding to point 2, and the signal strength corresponding to point 2 is higher than that corresponding to point 3. Based on points 1 and 2, a first region C can be determined. This first region C includes a spherical region with the shortest distance between points 1 and 2 as its diameter. Based on points 1 and 3, a first region D can be determined. This first region D also includes a spherical region with the shortest distance between points 1 and 3 as its diameter. The intersection of the first regions C and D is shown in the figure. Figure 3 The target area F shown is used as a pre-selected area, which is a three-dimensional area.

[0099] In some examples, if there are n key points and the n key points are located on different planes, the key point with the highest signal strength among the n key points can be selected as the target point. Based on the shortest distance between the target point and other key points as the diameter, n-1 first regions with spherical shapes are constructed. The intersection of the n-1 first regions is used as the pre-selected region.

[0100] Optionally, for details on the specific implementation process of determining the pre-selected area based on key locations, please refer to [link to relevant documentation]. Figure 4 and Figure 5 The steps shown are explained below.

[0101] In some examples, after determining the target test point, it is also necessary to use the target test point to perform signaling tests on the device under test in order to obtain the communication performance indicators of the device under test.

[0102] Optionally, signaling tests can be performed on the device under test based on the target test points to obtain the communication performance indicators of the device under test.

[0103] In some examples, after the target test location is determined, the target test location and the corresponding test mode can be uploaded to the cloud so that other test sites can directly obtain the target test location and the corresponding test mode, thereby improving the signaling testing efficiency of other test sites.

[0104] The process described in S101-S103 above determines the target test point based on the signal reception data of the device under test at multiple test points. Using the signal reception data as a reference can improve the reliability of the target test point and ensure the best performance of the target test point. In addition, it can effectively narrow the search range of the target test point in the test space, thus significantly improving the search efficiency of the target test point.

[0105] like Figure 4 The diagram shown is a flowchart illustrating another method for determining target test points provided in this application, which includes the following steps.

[0106] S401: Determine the first region based on the first and second key points.

[0107] The first region is a planar region.

[0108] In some examples, the first and second points are on the same plane.

[0109] In some examples, a circular region can be constructed based on the shortest distance between the first and second points as the diameter, and this circular region can be used as the first region.

[0110] In some examples, the signal strengths corresponding to the first and second points are the two highest among all key points, and the signal strength corresponding to the first point is higher than that corresponding to the second point.

[0111] Optionally, after determining the first region based on key points, a pre-selected region can be determined based on the key points and the first region, wherein the pre-selected region is at least a part of the first region.

[0112] In some examples, a pre-selected area is determined based on the key points and the first area. The specific implementation process can be seen in S402. Alternatively, the specific implementation process can also be: a portion of the first area corresponding to the specified orientation is used as the pre-selected area.

[0113] S402: Based on the third point in the key points, determine the second area based on the first area, and use the second area as the pre-selected area.

[0114] Among them, the first point, the second point, and the third point are test points where the signal strength received by the device under test meets the preset strength condition. In one possible implementation, the preset strength condition can be the test points whose signal strength ranks among the top three among all test points.

[0115] In some examples, the first point, the second point, and the third point are on the same plane.

[0116] In some examples, the signal strength at the second point is higher than that at the third point.

[0117] In one possible implementation, a second region is determined based on a third key point in the key locations, building upon the first region. This can be achieved by: using the shortest distance between the first and second key points as a dividing line to segment the first region, resulting in two semicircular regions; and selecting the semicircular region closest to the third key point as the second region. In another possible implementation, a portion of the second region can be selected as a pre-selected region.

[0118] S403: Based on the signal reception data of the device under test at multiple test points in the pre-selected area, determine the first reference point in the pre-selected area.

[0119] Among them, the signal strength received by the device under test at the first reference point meets the first strength condition.

[0120] In some examples, the first strength condition can be: the signal strength corresponding to the first reference point is the highest among all test points in the pre-selected area.

[0121] It should be noted that after determining the pre-selected area, the device under test is moved within the pre-selected area to obtain signal reception data at multiple test points within the pre-selected area.

[0122] In one possible implementation, such as Figure 2As shown, after determining the target area E as the pre-selected area, the device under test is controlled to perform multiple displacements within the pre-selected area. The direction and distance of each displacement can be set by technicians according to the actual situation to determine the test points corresponding to the multiple displacements.

[0123] S404: Determine the first baseline based on the first reference point and reference direction.

[0124] The reference direction and the plane containing the pre-selected area satisfy the angle condition.

[0125] In some examples, the included angle condition can be: perpendicular to the plane containing the pre-selected region.

[0126] In one possible implementation, a reference direction perpendicular to the plane containing the pre-selected area is determined, and multiple parallel points of the first reference point in that reference direction are obtained. The first reference point and the multiple parallel points are combined to construct a first baseline.

[0127] S405: Based on the signal reception data of the device under test at multiple test points on the first reference line, determine the target test point on the first reference line.

[0128] Among them, the signal strength received by the device under test at the target test point meets the second strength condition.

[0129] In some examples, the second strength condition can be: the signal strength corresponding to the target test point is the highest among all test points on the first baseline.

[0130] It should be noted that after determining the first baseline, the device under test is controlled to move along the first baseline to obtain signal reception data at multiple test points on the first baseline. This signal reception data can be the signal strength.

[0131] Understandably, by determining a first reference point from a pre-defined area, establishing a first baseline based on that reference point, and finally determining the target test point from that baseline, the search range for the target test point in the test space can be gradually narrowed from a large area to a small area, thus improving the efficiency of the target test point search. Furthermore, the determination of the key points, the first reference point, and the target test point is all based on the corresponding signal reception data, ensuring strong objectivity and guaranteeing that the final target test point obtained is the most effective.

[0132] The processes shown in S401-S405 above can effectively narrow down the search range of the target test point in the test space based on key points, thereby significantly improving the search efficiency of the target test point.

[0133] like Figure 5 The diagram shown is a flowchart illustrating another method for determining target test points provided in this application, which includes the following steps.

[0134] S501: Determine the first region based on the first and second key points.

[0135] The first area is a three-dimensional area.

[0136] In some examples, the first point and the second point can be on the same plane or on different planes.

[0137] In some examples, a spherical region can be constructed based on the shortest distance between the first and second points as the diameter, and this spherical region can be used as the first region.

[0138] In some examples, the signal strengths corresponding to the first and second points are the two highest among all key points, and the signal strength corresponding to the first point is higher than that corresponding to the second point.

[0139] Optionally, after determining the first region based on key points, a pre-selected region can be determined based on the key points and the first region. The pre-selected region is at least a part of the first region, and the pre-selected region can be an irregular three-dimensional region or a regular three-dimensional region.

[0140] S502: Based on the third point in the key points, determine the second area based on the first area, and use the second area as the pre-selected area.

[0141] Among them, the first point, the second point, and the third point are test points where the signal strength received by the device under test meets the preset strength condition. In one possible implementation, the preset strength condition can be the test points whose signal strength ranks among the top three among all test points.

[0142] In some examples, the first point, the second point, and the third point can be on different planes.

[0143] In some examples, the signal strength at the second point is higher than that at the third point.

[0144] In one possible implementation, a second region is determined based on a third key point among the key points, building upon the first region. This can be achieved by: using the shortest distance between the first and second key points as a dividing line to segment the first region, resulting in two hemispherical regions; and selecting the hemispherical region closest to the third key point as the second region. In another possible implementation, a portion of the second region can be selected as a pre-selected region.

[0145] S503: Based on the signal reception data of the device under test at multiple test points in the pre-selected area, determine the target test point in the pre-selected area.

[0146] Among them, the signal strength received by the device under test at the target test point meets the third strength condition.

[0147] In some examples, the third strength condition can be: the signal strength corresponding to the target test point is the highest among multiple test points in the pre-selected area.

[0148] It should be noted that after determining the pre-selected area, the device under test is moved within the pre-selected area to obtain signal reception data at multiple test points within the pre-selected area. This signal reception data can be the signal strength.

[0149] Understandably, determining the target test point from the pre-defined area effectively narrows the search range compared to determining the target test point from the test space and the first area, thus significantly improving the search efficiency of the target test point.

[0150] In some examples, multiple test points of the device under test in a pre-selected area are determined based on multiple displacements of the device under test in the pre-selected area. The direction and distance of each displacement can be set by technicians according to the actual situation.

[0151] The processes shown in S501-S503 above can effectively narrow the search range of the target test point in the test space based on key points, thereby significantly improving the search efficiency of the target test point.

[0152] Corresponding to the target test point determination method provided in the above embodiments of this application, the embodiments of this application also provide a target test point determination device.

[0153] like Figure 6 The diagram shown is a schematic representation of the architecture of a target test point determination device provided in an embodiment of this application, which includes the following units.
