DETAILED DESCRIPTION

[0034] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements in the several figures. The following exemplary embodiments described herein describe implementations consistent with the present application, but these implementations do not represent all implementations consistent with the present application. Instead, they are merely examples consistent with some aspects of the present application as detailed in the appended claims.

[0035] In the technical solutions of the present application, the collection, storage, use, processing, transmission, provision and disclosure of user personal information and data involved in the technical solutions comply with relevant laws and regulations and do not violate public order and good customs.

[0036] It should be noted that the user information (including but not limited to user equipment information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of relevant data need to comply with relevant laws and regulations and standards of relevant countries and regions, and provide corresponding operation portal for user to choose authorization or refusal.

[0037] The application scenarios of the embodiments of this application are explained below:

[0038] Figure 1 This is a schematic diagram illustrating a scenario for the NTN signal transmission direction adjustment method provided in this application, as shown below. Figure 1 As shown, the specific application scenario of this application is when a user uses a non-terrestrial network (NTN) communication device for satellite communication. The execution subject of the method provided in this application embodiment can be an electronic control unit, an electronic device, or a terminal device. Taking a terminal device as the execution subject, for example, the terminal device is an NTN communication device. Since satellite systems can remain far from the ground for extended periods and have a wide coverage area, with the development of satellite communication technology, NTN communication devices are increasingly used in areas where ground base stations cannot fully cover them to achieve information transmission. Furthermore, when a user uses an NTN communication device to transmit information between the NTN communication device and the satellite system, the communication stability depends on the accuracy of the transmission direction of the NTN signal emitted by the NTN communication device. Therefore, it is necessary to increase the number of antennas on the NTN communication device to ensure communication stability.

[0039] Based on the above scenarios, it can be seen that in the existing technology, by setting multiple antennas at different locations on the NTN communication device to ensure that the transmission direction of the NTN signal transmitted by the NTN communication device meets the communication requirements, the technical problem of the NTN communication device being too large has been caused.

[0040] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0041] Figure 2 A flowchart of an NTN signal transmission direction adjustment method provided in one embodiment of this application is shown below. Figure 2 As shown, the execution subject of the NTN signal transmission direction adjustment method provided in this embodiment can be an electronic control unit, an electronic device, or a terminal device. For example, this embodiment uses a terminal device as the execution subject of the method, such as an NTN communication device. The NTN signal transmission direction adjustment method provided in this embodiment includes the following steps:

[0042] Step S101: Based on the operating status of the NTN communication device, receive multiple GNSS signals sent by the satellite system and determine a preset angle range; wherein, the preset angle range includes a preset elevation angle range and a preset azimuth angle range.

[0043] Exemplarily, for the same NTN communication device, the number of GNSS signals received by the NTN communication device is different in different device operating states of the NTN communication device, and the corresponding preset angle intervals for angle interval division of the GNSS signals are also different. When the GNSS signals are divided into angle intervals, the GNSS signals are generally divided into angle intervals according to the elevation angle and the azimuth angle of the GNSS signals, and the preset angle intervals include preset elevation angle intervals and preset azimuth angle intervals. Specifically, for example, based on the working condition, the NTN communication device does not need to determine the direction of the GNSS signal transmission with high precision, and the NTN communication device is in a low-power consumption state. The number of GNSS signals received by the NTN communication device is X, and the angle range corresponding to the preset angle interval is large. Based on the working condition, the NTN communication device needs to determine the direction of the GNSS signal transmission with high precision, and the NTN communication device is in a high-power consumption state. The number of GNSS signals received by the NTN communication device is Y, and the angle range corresponding to the preset angle interval is small. Wherein X is less than Y.

[0044] In step S102, for each GNSS signal, the elevation angle of the satellite transmitting the GNSS signal relative to the NTN communication device, the azimuth angle of the satellite relative to the earth, and the GNSS signal strength of the GNSS signal received by the NTN communication device are determined.

[0045] Exemplarily, for the GNSS signal, the NTN communication device can determine the elevation angle of the satellite transmitting the GNSS signal relative to the NTN communication device, the azimuth angle of the satellite relative to the earth, the GNSS signal strength of the GNSS signal received by the NTN communication device, and the satellite number of the satellite transmitting the GNSS signal based on the communication protocol.

[0046] In step S103, for a plurality of GNSS signals, the plurality of GNSS signals are grouped according to the matching relationship between the elevation angle and the preset elevation angle interval and the matching relationship between the azimuth angle and the preset azimuth angle interval, and a GNSS signal strength statistical table is obtained.

[0047] Exemplarily, after the NTN communication device obtains the elevation angle, the azimuth angle, the signal strength and the satellite number of each GNSS signal based on the communication protocol, the plurality of GNSS signals can be grouped according to the matching relationship between the elevation angle and the preset elevation angle interval and the matching relationship between the azimuth angle and the preset azimuth angle interval, and a GNSS signal strength statistical table is obtained.

[0048] Specifically, for example, for a GNSS signal with an elevation angle of 45, an azimuth angle of 130, a signal strength of 30 and a satellite number of 10, the preset elevation angle interval includes three angle intervals of 0-30, 31-60 and 61-90, the preset azimuth angle interval includes four angle intervals of 0-90, 91-180, 181-270 and 271-360, and then, according to the fact that the elevation angle of 45 belongs to the preset elevation angle interval of 31-60 and the azimuth angle of 130 belongs to the preset azimuth angle interval of 91-180, the group of the GNSS signal is determined; and then, according to the matching relationship between the angle and the angle interval, the multiple GNSS signals are grouped, and thus the GNSS signal strength statistical table is obtained.

[0049] Further, in a possible implementation, the specific implementation steps of step S103 include:

[0050] Step S1031, for the multiple GNSS signals, according to the matching relationship between the elevation angle and the preset elevation angle interval and the matching relationship between the azimuth angle and the preset azimuth angle interval, the multiple GNSS signals are grouped according to the elevation angle and the azimuth angle, and thus the GNSS signal distribution statistical table is obtained.

[0051] Step S1032, according to the preset signal strength, the GNSS signals in the GNSS signal distribution statistical table are filtered, and thus the GNSS signal strength statistical table is obtained.

[0052] In an exemplary example, the NTN terminal device receives and analyzes the data of the determined GNSS signal as follows:

[0065] $GB,5,5,17,23,56,312,37,1*46

[0066] Wherein, the first capital letter of each line represents the type of satellite, the first digit represents the number of lines occupied by the data of the GNSS signal of the satellite of this type, the second digit represents the line number of the data of the GNSS signal of a certain satellite of this type in the total number of lines, and the third digit represents the number of satellites (the number of GNSS signals) of this type that the NTN communication device can receive. Taking "GB, 5, 4, 17" as an example, GB represents the satellite of the BEIDOU type, 5 represents that the data of the GNSS signal of the GB type occupies a total of 5 lines, 4 represents that the data of a certain GNSS signal of the GB type is in the fourth line, and 17 represents that the data of the GNSS signal of the GB type is a total of 17 (groups), and also represents that the number of satellites of the GB type is 17. The subsequent numbers are in groups of four digits, corresponding to the data of a GNSS signal. Taking "06, 62, 344, 28" as an example, 06 is the satellite number of the satellite, 62 is the elevation angle, 344 is the azimuth angle, and 28 is the signal strength. If the signal strength of the GNSS signal cannot be determined, but other data of the GNSS signal can be determined, "N / A" is marked in the position of the signal strength to indicate that the signal strength of the GNSS signal cannot be determined. Taking "13, 13, 217, N / A" as an example, 13 is the satellite number of the satellite, 13 is the elevation angle, 217 is the azimuth angle, and the signal strength cannot be determined, so N / A is used to occupy the position. The last digit of each line is a check symbol, for example, "1*74" is a check symbol, and "1*7B" is a check symbol. Further, the NTN communication device performs keyword recognition on the data of the above-mentioned GNSS signal to determine that there are 13 satellites of the GPS (GP) type, 5 satellites of the BEIDOU (GB) type, 5 satellites of the GLONASS (GL) type, and 17 satellites of the Galileo (GA) type, a total of 40 satellites.

[0067] Further, for each set of data corresponding to the above-mentioned GNSS signal, the NTN communication device groups the plurality of GNSS signals according to the matching relationship between the elevation angle and the preset elevation angle interval, the matching relationship between the azimuth angle and the preset azimuth angle interval, the elevation angle and the azimuth angle, to obtain a GNSS signal distribution statistical table. The GNSS signal distribution statistical table is shown in Table 1.

[0068] Table 1

[0069]

[0070] Further, the NTN communication device filters the GNSS signals in the GNSS signal distribution statistics table according to a preset signal strength to obtain a GNSS signal strength statistics table. Specifically, for example, when the signal strength of the GNSS signal is greater than or equal to the preset signal strength, the stability of the communication between the NTN communication device and the satellite system is better. Therefore, the GNSS signals in the GNSS signal distribution statistics table are filtered by the preset signal strength to obtain the GNSS signal strength statistics table. For example, the preset signal strength is 24, the GNSS signals in Table 1 are filtered, and the obtained GNSS signal strength statistics table is shown in Table 2.

[0071] Table 2

[0072]

[0073] Step S104, obtaining a GNSS signal strength reference table of the NTN communication device; wherein the GNSS signal strength reference table includes signal reference strengths in a preset angle interval.

[0074] For example, the NTN communication device is subjected to a receiving test of receiving signal strength, the signal strength of the reference signal is fixed, for example, 40, the elevation angle of the NTN communication device is 90, and then the antenna direction of the NTN communication device is rotated, and the signal reference strengths in the preset angle interval are recorded, that is, the GNSS signal strength reference table is obtained. The GNSS signal strength reference table is shown in Table 3.

[0075] Table 3

[0076]

[0077] Step S105, determining at least one candidate azimuth angle interval from the preset azimuth angle intervals of the GNSS signal strength statistics table according to the GNSS signal strengths of the plurality of GNSS signals.

[0078] For example, taking the grouping of the GNSS signals shown in Table 2 as an example, counting statistics are performed based on the dimension of the azimuth angle interval, and then the number of signals of the GNSS signals corresponding to each preset azimuth angle interval is obtained. For example, the number of signals of the GNSS signals corresponding to the preset azimuth angle interval 0-90 is 8, the number of signals of the GNSS signals corresponding to the preset azimuth angle interval 91-180 is 6, the number of signals of the GNSS signals corresponding to the preset azimuth angle interval 181-270 is 4, and the number of signals of the GNSS signals corresponding to the preset azimuth angle interval 271-360 is 8. The first two preset azimuth angle intervals are determined as the candidate azimuth angle intervals, that is, the preset azimuth angle interval 0-90 and the preset azimuth angle interval 271-360 are determined as the candidate azimuth angle intervals.

[0079] It can be understood that the above process is to determine the first two preset azimuth angle intervals as the to-be-selected azimuth angle intervals, or the first three, or the first one, and the embodiment of the present application does not make a specific limitation.

[0080] In step S106, the to-be-selected GNSS signal strength of each to-be-selected elevation angle interval is determined according to the at least one to-be-selected azimuth angle interval.

[0081] For example, according to the processing procedure in step S105, after the to-be-selected azimuth angle intervals are determined, the to-be-selected GNSS signal strength of each to-be-selected elevation angle interval can be determined. Specifically, for example, based on Table 2, the determination of the at least one to-be-selected azimuth angle interval is performed to obtain the to-be-selected GNSS signal strength statistical table as shown in Table 4.

[0082] Table 4

[0097]

[0098] Further, according to the maximum target GNSS signal intensity existing in the candidate azimuth angle interval 271-360 and the candidate elevation angle interval 0-90, the candidate azimuth angle interval 271-360 is determined as the target azimuth angle interval, and the candidate elevation angle interval 0-90 is determined as the target elevation angle interval.

[0100] Exemplarily, on the basis of obtaining the target azimuth angle interval and the target elevation angle interval, the NTN communication device can generate the target transmission direction information of the NTN signal; and then the NTN communication device adjusts the transmission direction of the NTN signal according to the target transmission direction information. Specifically, for example, the NTN communication device is an automated execution device (for example, a radar), and the NTN communication device adjusts its elevation angle and azimuth angle according to the target transmission direction information, so as to determine the transmission direction of the NTN signal.

[0101] Further, in another possible implementation, after obtaining the target transmission direction information of transmitting the NTN signal according to the target azimuth angle interval and the target elevation angle interval, the method further includes: generating and displaying a transmission direction angle adjustment diagram according to the target transmission direction information; wherein the transmission direction angle adjustment diagram is used to prompt a user to manually adjust the transmission direction of the NTN communication device for transmitting the NTN signal. Specifically, for example, the NTN communication device is a user handheld device, and the NTN communication device includes a display. Then, the NTN communication device generates the transmission direction angle adjustment diagram according to the target transmission direction information, and then displays the transmission direction angle adjustment diagram to the user on the display, so as to prompt the user to manually adjust the transmission direction of the NTN communication device for transmitting the NTN signal, and then realize stable communication between the NTN communication device and the satellite system.

[0102] The embodiment is applied to an NTN communication device. The NTN communication device receives a plurality of GNSS signals sent by a satellite system according to a device running state of the NTN communication device and determines a preset angle interval. The preset angle interval includes a preset elevation angle interval and a preset azimuth angle interval. For each GNSS signal, the NTN communication device analyzes to determine an elevation angle of a satellite sending the GNSS signal relative to the NTN communication device, an azimuth angle of the satellite relative to the earth, and a GNSS signal strength of the GNSS signal received by the NTN communication device. For the plurality of GNSS signals, the NTN communication device groups the plurality of GNSS signals according to a matching relationship between the elevation angle and the preset elevation angle interval and a matching relationship between the azimuth angle and the preset azimuth angle interval to obtain a GNSS signal strength statistical table. The NTN communication device obtains a GNSS signal strength reference table of the NTN communication device. The GNSS signal strength reference table includes a signal reference strength in the preset angle interval. The NTN communication device determines at least one candidate azimuth angle interval from the preset azimuth angle interval of the GNSS signal strength statistical table according to the GNSS signal strength of the plurality of GNSS signals. The NTN communication device determines candidate GNSS signal strengths of each candidate elevation angle interval according to the at least one candidate azimuth angle interval. The NTN communication device determines a target elevation angle interval from each candidate elevation angle interval and a target azimuth angle interval from the at least one candidate azimuth angle interval according to a size relationship between the candidate GNSS signal strengths of each candidate elevation angle interval and the signal reference strength. The NTN communication device obtains target transmission direction information of a NTN signal according to the target azimuth angle interval and the target elevation angle interval. The target transmission direction information is used to indicate adjustment of a transmission direction of the NTN communication device for transmitting the NTN signal. Based on the device running state, the received GNSS signals, and the preset angle interval, the NTN communication device analyzes each GNSS signal to determine the corresponding elevation angle, azimuth angle, and signal strength. Then, the NTN communication device groups the corresponding GNSS signals according to the preset angle interval, the elevation angle, and the azimuth angle to obtain the GNSS signal strength statistical table. Based on the GNSS signal strength statistical table, the NTN communication device determines at least one candidate azimuth angle interval and candidate GNSS signal strengths of each candidate elevation angle interval. Then, the NTN communication device determines the target azimuth angle interval and the target elevation angle interval according to the size relationship between the candidate GNSS signal strengths of each candidate elevation angle interval and the signal reference strength. Then, the NTN communication device obtains the target transmission direction information of the NTN signal. The NTN communication device solves the problem of excessive device volume of the NTN communication device caused by setting multiple antennas at different positions on the NTN communication device in the prior art.

[0103] Figure 3 The flowchart of the NTN signal transmission direction adjustment method provided for another embodiment of the present application is shown in Figure 3 The NTN signal transmission direction adjustment method provided by the embodiment is applied to an NTN communication device Figure 2The embodiment shown provides a method for adjusting the direction of NTN signal transmission. Based on the method, step S101 is further refined. The method for adjusting the direction of NTN signal transmission provided by the embodiment includes the following steps:

[0104] Step S201, according to the device running state, determine the device running environment of the NTN communication device, and receive a plurality of GNSS signals sent by the satellite system.

[0105] Step S202, according to the device running environment, determine the signal receiving accuracy.

[0106] Step S203, according to the signal receiving accuracy, determine the preset angle interval; wherein, the preset angle interval includes a preset elevation angle interval and a preset azimuth angle interval.

[0107] Exemplarily, for the same NTN communication device, the stability of communication between the NTN communication device and the satellite system is different under different device running environments. Therefore, according to the device running state, for example, according to the network address when the NTN communication device is running, the device running environment of the NTN communication device is determined; then according to the device running environment, the corresponding signal receiving accuracy is determined, for example, if the device running environment is complex and not conducive to communication, the corresponding signal receiving accuracy is high accuracy, if the device running environment is simple and conducive to communication, the corresponding signal receiving accuracy is low accuracy; then according to the signal receiving accuracy, the preset angle interval is determined, for example, if the signal receiving accuracy is high accuracy, the angle interval range of the corresponding preset angle interval is small, if the signal receiving accuracy is low accuracy, the angle interval range of the corresponding preset angle interval is large.

[0108] The implementation mode of the NTN communication device receiving a plurality of GNSS signals sent by the satellite system is the same as that of step S101, which will not be repeated here.

[0109] In one possible implementation, the specific implementation steps of step S202 include:

[0110] Step S2021, according to the device running environment, determine the environment complexity index.

[0111] Step S2022, judge the size relationship between the environment complexity index and the preset complexity index.

[0112] Step S2023, if the environment complexity index is greater than or equal to the preset complexity index, determine that the signal receiving accuracy is high receiving accuracy.

[0113] Step S2024, if the environment complexity index is less than the preset complexity index, determine that the signal receiving accuracy is low receiving accuracy.

[0114] Specifically, the complexity of the environment of the device running environment is quantified to obtain an environment complexity index, and then the size relationship between the environment complexity index and a preset complexity index is judged. If the environment complexity index is greater than or equal to the preset complexity index, the signal reception accuracy is determined to be high reception accuracy. If the environment complexity index is less than the preset complexity index, the signal reception accuracy is determined to be low reception accuracy.

[0115] Correspondingly, the specific implementation of step S203 is: determining a first preset angle interval according to the high reception accuracy; determining a second preset angle interval according to the low reception accuracy; wherein the angle interval range of the first preset angle interval is smaller than the angle interval range of the second preset angle interval, for example, the first preset angle interval includes a first preset elevation angle interval and a first preset azimuth angle interval, the second preset angle interval includes a second preset elevation angle interval and a second preset azimuth angle interval, the angle interval range of the first preset elevation angle interval is 15, and the angle interval range of the second preset elevation angle interval is 30, then the first preset elevation angle interval is 0-15, 16-30, 31-45, 46-60, 61-75, 76-90, a total of six angle intervals, and the second preset elevation angle interval is 0-30, 31-60, 61-90, a total of three angle intervals.

[0116] In the step of the embodiment of the application, based on the preset angle interval with a small angle interval range, the grouping of the GNSS signals can be more detailed, and finally the target azimuth angle interval and the target elevation angle interval determined in step S209 are also the angle intervals corresponding to the small angle interval range, that is, the target transmission direction information determined in step S210 is more accurate; further, due to the difference in the device running environment, the requirement for the accuracy of the target transmission direction information is different accordingly; and then by determining the corresponding preset angle interval according to the device running environment, data support is provided for the grouping of the GNSS signals in the subsequent steps, the corresponding preset angle interval is matched based on the actual needs, and the NTN communication device is prevented from generating high-accuracy target transmission direction information in a high-energy-consumption running state when only low-accuracy target transmission direction information is needed, thereby improving the control of the NTN communication device over energy consumption.

[0117] Step S204: For each GNSS signal, the elevation angle of the satellite transmitting the GNSS signal relative to the NTN communication device, the azimuth angle of the satellite relative to the earth, and the GNSS signal strength of the GNSS signal received by the NTN communication device are analyzed and determined.

[0118] Step S205: For a plurality of GNSS signals, the plurality of GNSS signals are grouped according to the matching relationship between the elevation angle and the preset elevation angle interval and the matching relationship between the azimuth angle and the preset azimuth angle interval, to obtain a GNSS signal strength statistical table.

[0119] Step S206, obtaining a GNSS signal strength reference table of the NTN communication device; wherein the GNSS signal strength reference table comprises signal reference strengths in preset angle intervals.

[0120] Step S207, determining at least one candidate azimuth angle interval from the preset azimuth angle intervals of the GNSS signal strength statistical table according to the GNSS signal strengths of the plurality of GNSS signals.

[0121] Step S208, determining candidate GNSS signal strengths of corresponding candidate elevation angle intervals according to the at least one candidate azimuth angle interval.

[0122] Step S209, determining a target elevation angle interval from the candidate elevation angle intervals and a target azimuth angle interval from the at least one candidate azimuth angle interval according to the size relationship between the candidate GNSS signal strengths of the candidate elevation angle intervals and the signal reference strengths.

[0123] Step S210, obtaining target transmission direction information of transmitting the NTN signal according to the target azimuth angle interval and the target elevation angle interval; wherein the target transmission direction information is used to indicate adjusting the transmission direction of the NTN communication device transmitting the NTN signal.

[0124] In this embodiment, the implementation manners of steps S204-S210 are the same as those of steps S102-S108 in the embodiment of the application shown in the Figure 2 application, which will not be repeated here.
