[0061] In one embodiment, Figure 2 As shown, an antenna beamforming method is provided, which is applied to Figure 1 The terminal 102 in the example is used as an example to illustrate, and the following steps are included:

[0068] It should be noted that in order to ensure that the antenna beam for the UAV device can be shaped later, it is necessary to determine the antenna beam direction of the target flight device before performing antenna beam shaping; specifically, when it is necessary to determine the antenna beam direction of the target flight device, the target relative position of the target flight device relative to the target antenna can be determined based on geographic data, and then, based on the target relative position, the antenna beam direction for the target flight device is determined so that the antenna beam direction can cover the target relative position.

[0069] In one embodiment of the present application, in order to determine the antenna beam direction of the target flying device, it is necessary to determine the target relative position of the target flying device in the spherical coordinate system with the target antenna as the origin based on ground data; then, based on the target relative position, determine the antenna beam direction that can cover the target flying device, that is, the antenna beam direction for the target flying device.

[0070] S203, performing antenna beamforming according to the initial received signal strength corresponding to the antenna beam direction, to obtain an antenna beam of the target antenna directed to the target flight device.

[0071] In one embodiment of the present application, during the process of antenna beam shaping, the beam parameters of the antenna beam can be determined according to actual needs, and then, the antenna beam of the target antenna for the target flight device can be obtained through the beam parameters; specifically, different beam parameters corresponding to different received signal strengths can be pre-specified, and then, after determining the initial received signal strength corresponding to the antenna beam direction, the antenna beam of the target antenna for the target flight device is determined according to the beam parameters corresponding to the initial received signal strength.

[0072] In another embodiment of the present application, the target direction weight can be determined according to the initial received signal strength corresponding to the antenna beam direction, and then the antenna beam is shaped according to the target direction weight to obtain the antenna beam of the target antenna for the target flight device.

[0073] The above-mentioned antenna beam forming method analyzes the beam direction of the target antenna through the geographic data of the target flight equipment that the target antenna communicates with the base station, obtains the antenna beam direction for the target flight equipment, and then, performs antenna beam forming according to the initial received signal strength corresponding to the antenna beam direction, and obtains the antenna beam of the target antenna for the target flight equipment. According to the above content, it can be known that in the process of shaping the antenna beam, the application will determine the antenna beam direction for the target flight equipment according to the geographic data of the target flight equipment; then, according to the antenna beam direction, determine the antenna beam of the target antenna for the target flight equipment, so as to achieve the corresponding antenna beam for the flight equipment in the low-altitude field according to the actual situation of different flight equipment, and ensure that the flight equipment can perform low-altitude services under the corresponding antenna beam, improve the network performance of the flight equipment under the antenna beam, ensure the smooth execution of low-altitude services, prevent fluctuations due to changes in the height difference between the flight equipment and the base station antenna, and ensure the stability of the flight equipment network signal.

[0074] In one embodiment, if Figure 3 As shown, when it is necessary to perform a beam direction analysis on the target antenna based on geographic data to obtain the antenna beam direction for the target flight device, the following contents may be specifically included:

[0075] S301, determining a target relative position of a target flight device with respect to a target antenna according to geographic data.

[0076] The target relative position refers to the corresponding coordinate position of the target flight device in the spherical coordinate system with the target antenna as the origin.

[0077] It should be noted that in order to obtain the target relative position of the target flight device, the initial relative position of the target flight device in the spatial rectangular coordinate system with the target antenna as the origin can be determined based on the geographic data of the target flight device, and then, based on the initial relative position, the target relative position of the target flight device relative to the target antenna can be determined.

[0078] Specifically, when it is necessary to determine the target relative position of the target flight device relative to the target antenna, the following may be specifically included: based on geographic data, determine the initial relative position of the target flight device in the spatial rectangular coordinate system with the target antenna as the origin; based on the mapping relationship between the spatial rectangular coordinate system and the spherical coordinate system with the target antenna as the origin, determine the target relative position of the target flight device in the spherical coordinate system according to the initial relative position.

[0079] In one embodiment of the present application, when it is necessary to determine the initial relative position of the target flight device in the spatial rectangular coordinate system with the target antenna as the origin, the geographic data can be substituted into the calculation formula (1), and then, the initial relative position of the target flight device in the spatial rectangular coordinate system with the target antenna as the origin can be obtained according to the calculation formula (1).

[0080] The calculation formula (1) is as follows:

[0081]

[0082] Among them, Lon1 refers to the longitude data of the target flight device in the geographic data; Lat1 refers to the dimension data of the target flight device in the geographic data; h1 refers to the height data of the target flight device in the geographic data; h0 refers to the altitude positioning standard; Lon0 refers to the longitude data positioning standard; Lat0 refers to the dimension data positioning standard; (x1, y1, z1) refers to the initial relative position of the target flight device in the spatial rectangular coordinate system with the target antenna as the origin.

[0083] As an example, the correspondence between the initial relative position (x1, y1, z1) of the target flight device and (Lon1, Lat1, h1) is as follows: Figure 4 shown.

[0084] Among them, d(Lon A , Lat A , Lon B , Lat B ) can be expressed by calculation formula (2):

[0085] d(Lon A , Lat A , Lon B , Lat B )

[0086] =R×arccos[cos(Lat A )×cos(Lat B )×cos(Lon A -Lon B )

[0087] +sin(Lat A )×sin(Lat B )] (2)

[0088] Among them, R refers to the radius of the earth, which is equal to 6320 kilometers; Lon A and Lon B Refers to longitude data; Lat A and Lat BRefers to dimensional data.

[0089] In one embodiment of the present application, when the target relative position of the target flight device in the spherical coordinate system is determined based on the mapping relationship between the spatial rectangular coordinate system and the spherical coordinate system with the target antenna as the origin according to the initial relative position, the mapping relationship between the spatial rectangular coordinate system and the spherical coordinate system with the target antenna as the origin can be characterized by calculation formula (3), and then, the initial relative position of the target flight device in the spatial rectangular coordinate system with the target antenna as the origin is substituted into calculation formula (3) to obtain the target relative position of the target flight device in the spherical coordinate system.

[0090] The calculation formula (3) is as follows:

[0091]

[0092] Among them, (x1, y1, z1) refers to the initial relative position of the target flight device in the spatial rectangular coordinate system with the target antenna as the origin; (r1, θ1, ) refers to the target relative position of the target flight device in the spherical coordinate system.

[0093] S302, performing a beam direction analysis on the target antenna according to the relative position of the target to obtain an antenna beam direction for the target flying device.

[0094] In one embodiment of the present application, after the relative position of the target is determined, the antenna beam orientation for the target flying device can be obtained by substituting the relative position of the target into calculation formula (4).

[0095]

[0096] Among them, θ realative It refers to the direction angle of the antenna beam along the vertical direction in the antenna beam direction; Refers to the direction angle of the antenna beam along the horizontal direction in the antenna beam direction; θ tilt Refers to the mechanical downtilt angle; refers to the absolute azimuth; θ1 and Refers to the target relative position of the target flight device in the spherical coordinate system.

[0097] As an example, θ realative , θ tilt , The corresponding relationship for the target flight equipment can be as follows Figure 5 As shown, the origin of the coordinate system is the target antenna.

[0098] The above-mentioned antenna beamforming method determines the target relative position of the target flight device relative to the target antenna, and then analyzes the beam direction of the target antenna according to the target relative position to obtain the antenna beam direction for the target flight device, thereby providing a data basis for subsequent antenna beamforming, ensuring the smooth progress of subsequent processes, ensuring that the flight device can perform low-altitude services under the corresponding antenna beam, and improving the network performance of the flight device under the antenna beam.

[0099] In one embodiment, if Figure 6 As shown, when it is necessary to perform antenna beamforming according to the initial received signal strength corresponding to the antenna beam direction to obtain the antenna beam of the target antenna for the target flight device, the following contents may be specifically included:

[0100] S601, determining a target direction weight according to an initial received signal strength corresponding to an antenna beam direction.

[0101] It should be noted that when it is necessary to determine the target direction weight, the following may be specifically included: determining the initial received signal strength corresponding to the antenna beam direction; performing power optimization on the initial received signal strength to obtain the target received signal strength; and determining the target direction weight based on the target received signal strength and the initial received signal strength.

[0102] Further explanation, when determining the target direction weight based on the target received signal strength and the initial received signal strength, it can include: determining the target angle gain value based on the power difference between the initial received signal strength and the target received signal strength; determining the target direction weight based on the target angle gain value.

[0103] In an embodiment of the present application, when it is necessary to determine the target direction weight according to the target angle gain value, it may include determining the target direction weight according to the target angle gain value based on the correspondence between the candidate gain values ​​and the candidate direction weights.

[0104] In another embodiment of the present application, in order to further improve the accuracy of determining the target direction weight, it is necessary to introduce the antenna beam direction in the process of determining the target direction weight. Specifically, the correspondence between the candidate gain value, the candidate beam direction and the candidate direction weight can be determined in advance, and the correspondence records different candidate gain values ​​and candidate beam directions, and the corresponding different candidate direction weights; then, the target direction weight is determined according to the correspondence, the target angle gain value and the antenna beam direction.

[0105] Specifically, determine the correspondence between the candidate gain values ​​and the candidate beam orientations and the candidate directional weights. After determining the target angle gain value and the antenna beam orientation, determine the reference gain value and the reference beam orientation that are the same as the target angle gain value and the antenna beam orientation from the candidate gain values ​​and the candidate beam orientations recorded in the correspondence. Then, determine the target directional weight based on the directional weights corresponding to the reference gain value and the reference beam orientation in the correspondence.

[0106] Specifically, a directional weight library can be constructed in advance. When the target directional weight is recorded in the directional weight library, it can include the correspondence between the candidate beam directions and the candidate gain values ​​and the candidate directional weights, that is, different candidate directional weights corresponding to different candidate gain values ​​and candidate beam directions. Furthermore, after determining the target angle gain value and the antenna beam direction, the candidate directional weight corresponding to the target angle gain value and the antenna beam direction in the directional weight library is used as the target direction weight.

[0107] It is further explained that when constructing the directional weight library, the base station unit directional pattern can be determined based on base station parameters such as the number of antenna array units, array spacing, array arrangement, etc.; then, according to different low-altitude business needs and the coverage heights of different unit directional patterns, combined with the historical experience of antenna operation and maintenance personnel and the actual settlement of the target flight equipment, the directional weight library is constructed.

[0108] In one embodiment of the present application, when it is necessary to perform power optimization on the initial received signal strength to obtain the target received signal strength, the initial received signal strength corresponding to the antenna beam direction can be power optimized according to a preset angle gain value to obtain a candidate received signal strength; determine whether the candidate received signal strength meets a preset condition; if so, use the candidate received signal strength as the target received signal strength; if not, update the preset angle gain value, use the candidate received signal strength as the new initial received signal strength, and return to execute the step of performing power optimization on the initial received signal strength corresponding to the antenna beam direction according to the preset angle gain value.

[0109] Further explanation, power optimization of the initial received signal strength corresponding to the antenna beam orientation can be achieved based on calculation formula (5) by using a preset angle gain value, wherein the preset angle gain value may include a first gain value for a new direction of the target received signal strength and a second gain value for a current direction of the initial received signal strength; specifically, calculation formula (5) is as follows:

[0110] RSRP(j)=RSRP(i)+G j -G i (5)

[0111] RSRP(j) refers to the target received signal strength; RSRP(i) refers to the initial received signal strength; G j and G i Refers to the first gain value and the second gain value.

[0112] Further explanation: when judging whether the candidate received signal strength meets the preset conditions, the candidate received signal strength can be scored to obtain an evaluation value corresponding to the candidate received signal strength, and then the relationship between the evaluation value and the preset evaluation value threshold is verified. If the evaluation value is greater than the evaluation value threshold, it is determined that the candidate received signal strength meets the preset conditions; if the evaluation value is not greater than the evaluation value threshold, it is determined that the candidate received signal strength does not meet the preset conditions.

[0113] The candidate received signal strengths can be scored based on calculation formula (6). Specifically, calculation formula (6) is as follows:

[0114] p i (t) = {p i1 (t),p i2 (t), ..., p in (t)}(i=1,2,...,N) (6)

[0115] Among them, p i Refers to the evaluation value corresponding to the candidate received signal strength.

[0116] S602, performing antenna beamforming according to the target direction weight to obtain an antenna beam of the target antenna directed to the target flight device.

[0117] In one embodiment of the present application, after determining the target direction weight, the beam parameters corresponding to the antenna beam can be determined according to the target direction weight, and then, linear beam forming is implemented according to the beam parameters to obtain the antenna beam of the target antenna for the target flight device.

[0118] The above-mentioned antenna beamforming method determines the target direction weight; then, performs antenna beamforming according to the target direction weight to obtain the antenna beam of the target antenna for the target flight device, thereby providing the corresponding antenna beam to the flight device in a targeted manner, ensuring that the flight device can perform low-altitude services under the corresponding antenna beam, improving the network performance of the flight device under the antenna beam, ensuring the smooth execution of low-altitude services, preventing fluctuations due to changes in the height difference between the flight device and the base station antenna, and ensuring the stability of the flight device network signal.

[0119] In one embodiment, if Figure 7 As shown, when it is necessary to determine the antenna beam of the target antenna for the target flight device, the following contents may be specifically included:
