These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0034] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0035] In the technical solution of this application, the user personal information involved and the collection, storage, use, processing, transmission, provision and disclosure of data are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0036] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0037] The following explains the application scenarios of the embodiments of the present application:

[0038] Figure 1 A schematic diagram of a scenario of the NTN signal transmission direction adjustment method provided in this application, such as Figure 1 As shown, the specific application scenario of the present application is a scenario when a user uses a non-terrestrial network (NTN) communication device for satellite communication. The execution subject of the method provided in the embodiment of the present application can be an electronic control unit, an electronic device or a terminal device. The terminal device is used as the execution subject for description. For example, the terminal device is an NTN communication device. Since the satellite system can be permanently away from the ground and has a wide coverage area, and with the development of satellite communication technology, NTN communication devices are subsequently used in areas that cannot be fully covered by ground base stations to achieve information transmission. Furthermore, when the user uses the NTN communication device to transmit information with the satellite system, its communication stability depends on the accuracy of the transmission direction of the NTN signal transmitted by the NTN communication device. Therefore, it is necessary to increase the number of antennas of the NTN communication device to ensure communication stability.

[0039] In view of the above scenario, in the prior art, multiple antennas at different positions are provided 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, which leads to the technical problem that the NTN communication device is too large.

[0040] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0041] Figure 2 A flowchart of a method for adjusting the NTN signal transmission direction provided by an embodiment of the present application is shown in FIG. Figure 2 As shown, the NTN signal transmission direction adjustment method provided in this embodiment may be executed by an electronic control unit, an electronic device, or a terminal device. By way of example, this embodiment uses a terminal device as the execution subject of the method of this embodiment for description. For example, the terminal device is an NTN communication device. The NTN signal transmission direction adjustment method provided in this embodiment includes the following steps:

[0042] Step S101: receiving a plurality of GNSS signals sent by a satellite system and determining a preset angle interval according to the device operation status of the NTN communication device; wherein the preset angle interval includes a preset elevation angle interval and a preset azimuth angle interval.

[0043] For example, for the same NTN communication device, under different operating states, the number of GNSS signals transmitted by satellite systems received varies, and the corresponding preset angle intervals for dividing the GNSS signals into angle intervals also vary. The angle intervals for dividing the GNSS signals into angle intervals are generally divided based on the elevation and azimuth angles of the GNSS signals, and the preset angle intervals include a preset elevation interval and a preset azimuth interval. Specifically, for example, if, based on operating conditions, the NTN communication device is not required to determine the high-precision GNSS signal transmission direction, the NTN communication device is in a low-power state, the number of GNSS signals transmitted by the satellite systems received by the NTN communication device is X, and the angular range corresponding to the preset angle interval is large. If, based on operating conditions, the NTN communication device is required to determine the high-precision GNSS signal transmission direction, the NTN communication device is in a high-power state, the number of GNSS signals transmitted by the satellite systems received by the NTN communication device is Y, and the angular range corresponding to the preset angle interval is small, where X is less than Y.

[0044] Step S102 : For each GNSS signal, analyze and 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, and the GNSS signal strength of the GNSS signal received by the NTN communication device.

[0045] For example, for GNSS signals, the NTN communication device analyzes and processes the GNSS signals based on the communication protocol to 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 transmitting the GNSS signal.

[0046] Step S103 : grouping 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, to obtain a GNSS signal strength statistics table.

[0047] For example, after the NTN communication device obtains the elevation angle, azimuth angle, signal strength and satellite number of each GNSS signal based on the communication protocol analysis, the above multiple GNSS signals can be grouped according to the matching relationship between the elevation angle and the preset elevation angle range, and the matching relationship between the azimuth angle and the preset azimuth angle range to obtain a GNSS signal strength statistics table.

[0048] Specifically, for example, for a GNSS signal, its elevation angle is 45, azimuth angle is 130, signal strength is 30 and satellite number is 10, the preset elevation angle interval includes three angle intervals of 0-30, 31-60, and 61-90, and the preset azimuth angle interval includes four angle intervals of 0-90, 91-180, 181-270, and 271-360. Then, based on 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 based on the matching relationship between the above angles and angle intervals, the above multiple GNSS signals are grouped to obtain a GNSS signal strength statistics table.

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

[0050] In step S1031, for a plurality of GNSS signals, the plurality of GNSS signals are grouped according to a matching relationship between the elevation angle and a preset elevation angle interval, and a matching relationship between the azimuth angle and a preset azimuth angle interval, to obtain a GNSS signal distribution statistics table.

[0051] Step S1032 : Filter the GNSS signals in the GNSS signal distribution statistics table according to the preset signal strength to obtain a GNSS signal strength statistics table.

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

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

[0066] The first capital letter of each line indicates the type of satellite, the first digit indicates the number of lines occupied by the GNSS signal data of this type of satellite, the second digit indicates the line number of the GNSS signal data of a certain satellite of this type in the total number of lines, and the third digit indicates the number of satellites of this type that can be received by NTN communication equipment (the number of GNSS signals). Taking "GB,5,4,17" as an example, GB indicates a BEIDOU satellite, 5 indicates that the data of GB GNSS signals total 5 lines, 4 indicates that the data of several GB GNSS signals are in the fourth line, 17 indicates that the data of GB GNSS signals total 17 (groups), and also indicates the satellites of GB satellites. There are 17 satellites. The following numbers are grouped into four digits, corresponding to the data of one GNSS signal. For example, in "06,62,344,28", 06 is the satellite number, 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 GNSS signal data can be determined, "N / A" is used in place of the signal strength. For example, in "13,13,217,N / A", 13 is the satellite number, 13 is the elevation angle, and 217 is the azimuth angle. If the signal strength cannot be determined, N / A is used as a placeholder. The last digit of each line is the check digit. For example, "1*74" is the check digit, and "1*7B" is the check digit. Furthermore, NTN communication equipment performs keyword recognition on the data of the above GNSS signals and determines that there are 13 GPS (GP) type satellites, 5 BEIDOU (GB) type satellites, 5 GLONASS (GL) type satellites, and 17 Galileo (GA) type satellites, totaling 40 satellites.

[0067] Furthermore, for the set of data corresponding to each of the above GNSS signals, the NTN communication device groups multiple GNSS signals according to the matching relationship between the elevation angle and the preset elevation angle range, and the matching relationship between the azimuth angle and the preset azimuth angle range, to obtain a GNSS signal distribution statistics table, as shown in Table 1.

[0068] Table 1

[0069]

[0070] Furthermore, the NTN communication device filters the GNSS signals in the GNSS signal distribution statistical table according to the preset signal strength to obtain the GNSS signal strength statistical 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 statistical table are filtered according to the preset signal strength to obtain the GNSS signal strength statistical table. For example, if the preset signal strength is 24, the GNSS signals in Table 1 are filtered, and the obtained GNSS signal strength statistical 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 within a preset angle interval.

[0074] Exemplarily, a reception test of the received signal strength is performed on the NTN communication device, the signal strength of the reference signal is fixed, for example, to 40, and the elevation angle relative to the NTN communication device is 90. Then, the antenna direction of the NTN communication device is rotated, and the signal reference strength in the preset angle range is recorded to obtain a GNSS signal strength reference table. The GNSS signal strength reference table is shown in Table 3.

[0075] Table 3

[0076]

[0077] Step S105 : determining at least one azimuth interval to be selected from the preset azimuth intervals in 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 GNSS signals shown in Table 2 as an example, counting statistics are performed based on the dimension of the azimuth interval to obtain the number of GNSS signals corresponding to each preset azimuth interval. For example, the number of GNSS signals corresponding to the preset azimuth interval 0-90 is 8, the number of GNSS signals corresponding to the preset azimuth interval 91-180 is 6, the number of GNSS signals corresponding to the preset azimuth interval 181-270 is 4, and the number of GNSS signals corresponding to the preset azimuth interval 271-360 is 8; the signals are arranged from most to least according to the number of signals, and the first two preset azimuth intervals are determined as the azimuth intervals to be selected, that is, the preset azimuth interval 0-90 and the preset azimuth interval 271-360 are determined as the azimuth intervals to be selected.

[0079] It can be understood that the above process is to determine the first two preset azimuth angle intervals as the selected azimuth angle intervals, which can also be the first three or the first one. The embodiment of the present application does not impose specific restrictions on this.

[0080] Step S106 : determining the candidate GNSS signal strengths of the corresponding candidate elevation angle intervals according to the at least one candidate azimuth angle interval.

[0081] For example, after determining the candidate azimuth intervals according to the processing of step S105, the candidate GNSS signal strengths for the corresponding candidate elevation intervals can be determined. Specifically, for example, based on Table 2, at least one candidate azimuth interval is determined to obtain the candidate GNSS signal strength statistics table shown in Table 4.

[0082] Table 4

[0083]

[0084] Step S107 , determining a target elevation angle interval from each candidate elevation angle interval and determining a target azimuth angle interval from at least one candidate azimuth angle interval according to the magnitude relationship between the candidate GNSS signal strength and the signal reference strength in each candidate elevation angle interval.

[0085] Exemplarily, in each preset angle interval, a size comparison is performed based on the candidate GNSS signal strength of each candidate GNSS signal shown in Table 4 and the signal reference strength shown in Table 3, and the candidate GNSS signal strength greater than the signal reference strength is determined as the target GNSS signal strength, obtaining a target GNSS signal strength statistical table as shown in Table 5.

[0088] Furthermore, since the number of target GNSS signals corresponding to the target GNSS signal strength in the selected azimuth interval 271-360 is greater than the number of target GNSS signals corresponding to the target GNSS signal strength in the selected azimuth interval 0-90, the azimuth interval 271-360 is determined as the target azimuth interval; further, since the maximum target GNSS signal strength exists in the selected elevation interval 0-90, the selected elevation interval 0-90 is determined as the target elevation interval.

[0089] Furthermore, in another possible implementation, the specific implementation of step S107 includes:

[0090] Step 1071 , average the strength of the candidate GNSS signals in each candidate elevation angle interval to obtain the corresponding average signal strength.

[0091] Step 1072: Determine a target elevation angle interval from each candidate elevation angle interval and a target azimuth angle interval from at least one candidate azimuth angle interval based on the magnitude relationship between the average signal strength and the reference signal strength.

[0092] Exemplarily, based on the candidate GNSS signal strengths of the candidate GNSS signals shown in Table 4, the candidate GNSS signal strengths in each candidate elevation angle interval are averaged to obtain the corresponding signal average strength, as shown in Table 6.

[0093] Table 6

[0094]

[0095] Furthermore, in each preset angle interval, based on the signal average strength shown in Table 6 and the signal reference strength shown in Table 3, a size comparison is performed, and the signal average strength greater than the signal reference strength is determined as the target GNSS signal strength, obtaining the target GNSS signal strength statistical table shown in Table 7.

[0096] Table 7

[0097]

[0098] Furthermore, since the maximum target GNSS signal strength exists in the candidate azimuth interval 271-360 and the candidate elevation interval 0-90, the candidate azimuth interval 271-360 is determined as the target azimuth interval, and the candidate elevation interval 0-90 is determined as the target elevation interval.

[0099] Step S108 , obtaining target transmission direction information for 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 adjustment of the transmission direction of the NTN signal transmitted by the NTN communication device.

[0100] For example, based on the target azimuth angle range and target elevation angle range, the NTN communication device can generate target transmission direction information for transmitting the NTN signal. This information can then be used to adjust the transmission direction of the NTN signal. Specifically, if the NTN communication device is an automated execution device (e.g., a radar), the NTN communication device can adjust its own elevation and azimuth angles based on the target transmission direction information to determine the transmission direction of the NTN signal.

[0101] Furthermore, in another possible implementation, after obtaining target transmission direction information for transmitting NTN signals based on the target azimuth angle interval and the target elevation angle interval, the method further includes generating and displaying a transmission direction angle adjustment diagram based on 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 signal transmitted by the NTN communication device. Specifically, for example, the NTN communication device is a user handheld device including a display. Furthermore, the NTN communication device generates the transmission direction angle adjustment diagram based on the target transmission direction information and displays the transmission direction angle adjustment diagram to the user on the display, thereby prompting the user to manually adjust the transmission direction of the NTN signal transmitted by the NTN communication device, thereby achieving stable communication between the NTN communication device and the satellite system.

[0102] This embodiment is applied to an NTN communication device. By receiving multiple GNSS signals sent by a satellite system and determining a preset angle interval according to the device operation status of the NTN communication device, wherein the preset angle interval includes a preset elevation angle interval and a preset azimuth angle interval; for each GNSS signal, analyzing and determining 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; for multiple GNSS signals, grouping 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, to obtain a GNSS signal strength statistics table; and obtaining a GNSS signal strength reference table of the NTN communication device; wherein, GNSS The SS signal strength reference table includes signal reference strengths in preset angle intervals; based on the GNSS signal strengths of multiple GNSS signals, at least one candidate azimuth interval is determined from the preset azimuth intervals in the GNSS signal strength statistics table; based on the at least one candidate azimuth interval, the candidate GNSS signal strengths of the corresponding respective candidate elevation intervals are determined; based on the magnitude relationship between the candidate GNSS signal strengths and the signal reference strengths in each candidate elevation interval, a target elevation interval is determined from each candidate elevation interval, and a target azimuth interval is determined from at least one candidate azimuth interval; based on the target azimuth interval and the target elevation interval, target transmission direction information for transmitting the NTN signal is obtained; wherein the target transmission direction information is used to indicate adjustment of the transmission direction of the NTN signal transmitted by the NTN communication device. Based on the received GNSS signal and the preset angle interval determined according to the operating status of the device, the corresponding elevation angle, azimuth angle and signal strength are determined by analyzing each GNSS signal. The corresponding GNSS signals are then grouped according to the preset angle interval, elevation angle and azimuth angle to obtain a GNSS signal strength statistics table. On this basis, at least one to-be-selected azimuth angle interval and the corresponding to-be-selected GNSS signal strength of each to-be-selected elevation angle interval are determined from the preset azimuth angle interval in the GNSS signal strength statistics table. The target azimuth angle interval and the target elevation angle interval are determined based on the relationship between the to-be-selected GNSS signal strength of each to-be-selected elevation angle interval and the signal reference strength, thereby obtaining the target transmission direction information of the transmitted NTN signal. This solves the problem of excessively large device size of the NTN communication device caused by setting multiple antennas at different positions on the NTN communication device in the prior art solution.

[0103] Figure 3 A flowchart of a method for adjusting the NTN signal transmission direction provided by another embodiment of the present application is shown in FIG. Figure 3 As shown, the NTN signal transmission direction adjustment method provided by this embodiment is Figure 2Based on the NTN signal transmission direction adjustment method provided in the illustrated embodiment, step S101 is further refined. The NTN signal transmission direction adjustment method provided in this embodiment includes the following steps:

[0104] Step S201 : determining the device operating environment of the NTN communication device according to the device operating state, and receiving a plurality of GNSS signals sent by the satellite system.

[0105] Step S202: Determine the signal reception accuracy based on the device operating environment.

[0106] Step S203: determining a preset angle interval according to the signal reception accuracy; 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 may be different under different device operating environments. Furthermore, the device operating environment of the NTN communication device is determined based on the device operating state, for example, based on the network address of the NTN communication device during operation. Furthermore, the corresponding signal reception accuracy is determined based on the device operating environment. For example, if the device operating environment is complex and not conducive to communication, the corresponding signal reception accuracy is high; and if the device operating environment is simple and conducive to communication, the corresponding signal reception accuracy is low. Furthermore, a preset angle interval is determined based on the signal reception accuracy. For example, if the signal reception accuracy is high, the corresponding preset angle interval has a small angle interval range; and if the signal reception accuracy is low, the corresponding preset angle interval has a large angle interval range.

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

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

[0110] Step S2021: Determine the environment complexity index based on the device operating environment.

[0111] Step S2022: Determine the magnitude 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, the signal reception accuracy is determined to be high reception accuracy.

[0113] Step S2024: If the environment complexity index is less than the preset complexity index, the signal reception accuracy is determined to be low reception accuracy.

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

[0115] Correspondingly, the specific implementation method of step S203 is: determine the first preset angle interval according to the height reception accuracy; determine the 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 the first preset elevation angle interval and the first preset azimuth angle interval, the second preset angle interval includes the second preset elevation angle interval and the 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 steps of the embodiment of the present application, based on the preset angle interval with a small angle interval range, the grouping of GNSS signals can be more detailed, and the target azimuth angle interval and the target elevation angle interval finally determined in step S209 are also the corresponding angle intervals with a small angle interval range, that is, the target transmission direction information determined in step S210 is more accurate; furthermore, due to different device operating environments, the requirements for the accuracy of the target transmission direction information are correspondingly different; furthermore, by determining the corresponding preset angle interval according to the device operating environment, data support is determined for the GNSS signal grouping in subsequent steps, and the corresponding preset angle interval is matched based on actual needs, thereby avoiding the NTN communication device generating high-accuracy target transmission direction information in a high-energy consumption operating state when only low-accuracy target transmission direction information is required, thereby improving the energy consumption control of the NTN communication device.

[0117] Step S204 : For each GNSS signal, analyze and 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, and the GNSS signal strength of the GNSS signal received by the NTN communication device.

[0118] In step S205 , 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 statistics table.

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

[0120] Step S207 : determining at least one azimuth interval to be selected from the preset azimuth intervals in the GNSS signal strength statistics table according to the GNSS signal strengths of the plurality of GNSS signals.

[0121] Step S208 : determining the candidate GNSS signal strengths of the 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 each candidate elevation angle interval and determining a target azimuth angle interval from at least one candidate azimuth angle interval based on the magnitude relationship between the candidate GNSS signal strength and the signal reference strength in each candidate elevation angle interval.

[0123] Step S210 , obtaining target transmission direction information for 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 adjustment of the transmission direction of the NTN signal transmitted by the NTN communication device.

[0124] In this embodiment, the implementation of steps S204 to S210 is the same as that of the present application. Figure 2 The implementation methods of steps S102 to S108 in the illustrated embodiment are the same and will not be described in detail here.
