Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a beam adjustment method, apparatus, and electronic device. Background Art

[0002] The existing network device antenna design aims to ensure coverage of ground terminals. According to the deployment scenario, the network device coverage types can generally be divided into area coverage and line coverage. The existing network design is basically for ground terminals operating on the ground. Whether it is line coverage or area coverage, the network device uses a two-dimensional coverage method. With the continuous development of flight terminal technologies and the rapid expansion of flight terminal application scenarios such as flight terminal delivery, flight terminal logistics, low-altitude inspection, and low-altitude rescue, it is urgent to improve the communication service quality of low-altitude flight terminals. The main difference between low-altitude coverage (for example, generally referring to 100 - 600m) and ground coverage is that low-altitude coverage needs to consider the coverage height, which is three-dimensional stereoscopic coverage, and there are fewer reflecting objects in the air. Therefore, the areas that need to be covered must have the beam of the network device aligned and directed towards these areas. Currently, in the process of low-altitude coverage by network devices in related technologies, there will be a problem of low-altitude top holes (unable to be covered).

[0003] Currently, to solve the problem of low-altitude coverage holes, the commonly used method is to add more network devices on communication towers (signal towers), resulting in a relatively high equipment cost. Summary of the Invention

[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] Refer to Figure 1 , Figure 1 It is a flowchart of a beam adjustment method provided by an embodiment of the present application and is executed by a first network device. As Figure 1 shown, the beam adjustment method provided in this embodiment includes the following steps:

[0043] Step 101: Receive a measurement report of the flight terminal;

[0044] Step 102: Based on the measurement report, adjust the beam emission direction of the first network device.

[0045] It should be understood that the measurement report of the flight terminal can reflect relevant status information of the flight terminal, etc. In addition, it should be noted that since it is a flight scenario, the number of flight terminals flying in the air is generally limited and not continuous all the time. It is necessary to be able to cover but not require real-time coverage. As long as network coverage can be provided when there are terminals flying, in this embodiment, the beam coverage can be adjusted according to the measurement report of the flight terminal, and there is no need to set up many network devices for coverage, which can reduce costs.

[0046] That is, in the embodiment of the present application, the first network device receives the measurement report of the flight terminal and uses the measurement report of the flight terminal to adjust the beam emission direction of the first network device to adapt to the flight terminal, so as to improve the coverage effect on the flight terminal. There is no need to additionally set up many network devices to cover the flight terminal, reducing equipment costs. At the same time, by adjusting the beam emission direction of the first network device according to the measurement report of the flight terminal, the emitted beam can provide network coverage for the flight terminal more accurately, and the coverage holes for the flight terminal can be reduced.

[0047] In some embodiments, the measurement report includes at least one of the following:

[0048] The position of the flight terminal;

[0049] The speed of the flight terminal.

[0050] As an example, the location may include information such as longitude, latitude, and altitude. As an example, the speed of the flying terminal may include a first speed in a first direction, a second speed in a second direction, and a third speed in a third direction, where the first direction, the second direction, and the third direction are perpendicular to each other. That is, the speed of the flying terminal in the measurement report may be the speed including three mutually perpendicular directions. The first network device adjusts the beam emission direction based on at least one of the location and speed of the flying terminal to adapt to the flying terminal and improve the coverage effect on the flying terminal. Exemplarily, the first direction may be the north-south direction, the second direction may be the east-west direction, and the third direction may be the up-down direction. Exemplarily, the measurement report may further include the reference signal received power (RSRP) of the flying terminal, etc.

[0051] In some embodiments, the measurement report includes the speed of the flying terminal;

[0052] Among them, based on the measurement report, adjusting the beam emission direction of the first network device includes:

[0053] Obtain the initial location of the flying terminal, where the initial location is the location where the flying terminal switches to the serving cell of the first network device;

[0054] Based on the initial location and the speed of the flying terminal, determine the target location of the flying terminal;

[0055] According to the target location, adjust the beam emission direction of the first network device.

[0056] When the speed of the flying terminal is included in the measurement report, during the process of adjusting the beam emission direction, the location where the flying terminal switches to the serving cell of the first network device, that is, the initial location, may be obtained first, and then the target location of the flying terminal can be determined through the speed and the initial location of the flying terminal. It can be understood that the target location is the location at the target time, and the target time may be any time after the flying terminal switches to the serving cell of the first network device. Then, adjust the beam emission direction according to the target location of the flying terminal to make the beam emission direction more adaptable to the location of the flying terminal and improve the network coverage effect on the flying terminal.

[0057] Exemplarily, after the flying terminal switches to the serving cell of the first network device, the first network device may calculate the target location every other period (for example, t seconds), and adjust the beam emission direction once every time the target location is calculated to better provide network coverage for the flying terminal.

[0058] In some embodiments, according to the target location, adjusting the beam emission direction of the first network device includes:

[0059] Based on the target location, determine the beam emission angle;

[0060] Adjust the first network device to perform beam transmission at a beam transmission angle, where the flying terminal is within the coverage range of the beam transmitted at the beam transmission angle under the target position.

[0061] That is, in the process of adjusting the beam transmission direction using the target position, first determine the required beam transmission angle through the target position. It should be understood that the beam transmitted by the first network device at this beam transmission angle can cover the flying terminal at the target position, and the first network device performs beam transmission at this beam transmission angle to improve the coverage effect on the flying terminal.

[0062] In one example, in the process of determining the beam transmission angle based on the target position, the preset corresponding relationship can be searched according to the target position to determine the beam transmission angle matching the target position, where the preset corresponding relationship is the corresponding relationship between the pre-set position and the beam transmission angle. In another example, the relative position between the target position and the position of the first network device can be determined, and according to the relative position, the first coordinate position (the coordinates of the flying terminal in the coordinate system with the first network device as the origin, including two coordinate components, for example, can be expressed as (Bx, By)) can be calculated. According to the first coordinate position, the second coordinate position (for example, can be expressed as (Bx’, By’)) can be determined. The second coordinate position is the position regarding the first coordinate position and the transmission angle parameter. The elliptical expression is determined according to the second coordinate position, and the angular range of the transmission angle parameter is solved when the elliptical expression satisfies less than or equal to (≤) 1, and the beam transmission angle is determined within the angular range, where the elliptical expression is Bx’ 2 / a 2 +By’ 2 / b 2 , where Bx’ is one coordinate component in the second coordinate position, By’ is the other coordinate component in the second coordinate position, where the major axis radius a = tanθ1 * (H - h) and the minor axis radius b = tanθ2 * (H - h), θ1 is the first preset angle, θ2 is the second preset angle, both of which can be pre-set. For example, θ1 and θ2 can be preset according to the beam information (such as the beam angle) of the first network device. For example, for an 8TR device, the maximum number of horizontal dimension beams is 2, each beam is 65°, and the vertical dimension beam is 1 beam with a beam of 6°. Then θ1 can be half of the total horizontal dimension beam angle (2 * 65°), that is, 65°, and θ2 can be half of the total vertical dimension beam angle (1 * 6°), that is, 3°. H is the height B in the target position heig, where h is the height of the first network device, and H - h represents the relative height. Bx’ = Bx * cos(θ) + By * sin(θ), By’ = -Bx * sin(θ) + By * cos(θ), * represents the multiplication sign, Bx is one coordinate component in the first coordinate position, By is the other coordinate component in the first coordinate position, θ represents the emission angle parameter, which is the parameter to be solved. If within the elliptical coverage range, then Bx’ 2 / a 2 +By’ 2 / b 2 ≤1. In the elliptical expression, θ is the unknown to be solved. Thus, by solving Bx’ 2 / a 2 +By’ 2 / b 2 ≤1, the angular range of θ can be obtained. Sending the beam at the emission angle within this angular range can cover the flying terminal at the target position. Thus, any angle within the angular range can be selected as the beam emission angle, and the first network device emits the beam at this beam emission angle to improve the coverage effect on the flying terminal. In one example, Bx = Δ’ lat *R / (180 / π), By = Δ’ long *(R * cos(B lat )) / (180 / π), Δ’ lat is the relative latitude (which can also be understood as the latitude difference) between the latitude B at the target position and the latitude C at the position of the first network device lat and the relative longitude (which can also be understood as the longitude difference) between the longitude B at the target position and the longitude C at the position of the first network device lat , Δ’ lat = B lat - C lat , and the unit can be degrees. Δ’ long is the relative longitude (which can also be understood as the longitude difference) between the longitude B at the target position and the longitude C at the position of the first network device long , Δ’ long = B long - C long , and the unit can be degrees. long

[0063] In some embodiments, receive the measurement report of the flying terminal, including:

[0064] Receive the measurement report sent by the flying terminal, and the flying terminal is within the service cell range of the first network device.

[0065] That is, when the flying terminal is within the service cell range of the first network device, direct communication can be established between the flying terminal and the first network device. The flying device sends the measurement report to the first network device, and the first network device receives the measurement report sent by the flying terminal.

[0066] In some embodiments, before receiving the measurement report sent by the flying terminal, it further includes:

[0067] In the case where the flying terminal switches to the serving cell of the first network device, send a first signaling to the flying terminal, where the first signaling is used to instruct the flying terminal to report the measurement report periodically according to a first period.

[0068] When the flying terminal is in the serving cell of the first network device, the first network device can instruct the flying terminal to report the measurement report periodically every other first period. The flying terminal can obtain and report the measurement report to the first network device every other first period. In this way, the flying terminal can report the latest high measurement report to the first network device every other first period, so as to improve the accuracy of the first network device adjusting the transmission beam according to the measurement report.

[0069] In some embodiments, receiving the measurement report sent by the flying terminal includes:

[0070] Receiving the measurement report sent periodically by the flying terminal according to the first period;

[0071] Among them, based on the measurement report, adjusting the beam emission direction of the first network device includes: periodically adjusting the beam emission direction of the first network device based on the measurement report according to a second period; the second period is a positive integer multiple of the first period.

[0072] That is, when the flying terminal is in the serving cell of the first network device, the flying terminal can report the measurement report to the first network device periodically according to the first period according to the indication of the first signaling of the first network device. The first network device can adjust the beam emission direction of the first network device periodically according to the second period through the measurement report to adapt to the flying terminal and improve the coverage effect on the flying terminal.

[0073] In addition, it should be noted that during the process of periodically adjusting the beam emission direction of the first network device based on the measurement report according to the second period, the target position of the flying terminal is periodically determined based on the initial position and the speed of the flying terminal according to the second period, that is, the target position is calculated once every second period. In one example, for instance, the second period is t (the unit can be seconds), and the first period is T (the unit can be milliseconds). Within t seconds, the flying terminal can report m (i.e., t / T) measurement reports, and each measurement report includes the position and speed. The method for calculating the target position in each second period may include: calculating the first total speed of m first speeds within the second period, calculating the second total speed of m second speeds within the second period, and calculating the third total speed of m third speeds within the second period; calculating the first distance based on the first total speed and the second period, calculating the second distance based on the second total speed and the second period, and calculating the altitude change amount based on the third total speed and the second period; calculating the latitude change amount based on the first distance and the radius of the earth, calculating the longitude change amount based on the second distance and the radius of the earth; obtaining the target latitude based on the initial latitude in the initial position and the latitude change amount, obtaining the target longitude based on the initial longitude in the initial position and the longitude change amount, and obtaining the target altitude based on the altitude in the initial position and the altitude change amount. In this way, the determination of the target position within the second period is completed, that is, the target position includes the target latitude, the target longitude, and the target altitude.

[0074] In some embodiments, receiving the measurement report of the flying terminal includes:

[0075] Receiving the measurement report sent by the second network device, where the flying terminal is within the service cell range of the second network device, and the measurement report is sent by the flying terminal to the second network device when the reference signal received power (RSRP) is less than a preset threshold value. The measurement report includes the position of the flying terminal.

[0076] The first network device and the second network device are different network devices. The first network device and the second network device can communicate through an Xn link. If there is no Xn link established between the first network device and the second network device, they can also communicate through the core network NG link. The physical transmission medium between them can be direct fiber connection or through a switch, etc. In this embodiment, the flying terminal is within the service cell range of the second network device. The flying terminal can directly communicate with the second network device. The flying terminal reports the measurement report to the second network device, and the second network device transmits the measurement report to the first network device. In one example, the first network device receives the measurement report sent by the second network device through the Xn link between them. In one example, the first network device and the second network device are adjacent, and they use the Xn link to transmit the measurement report. In another example, the first network device and the second network device can be located on the same signal tower. In this way, the transmission distance between the first network device and the second network device is short, which can improve the accuracy and security of the measurement report transmission.

[0077] In this embodiment, the flying terminal is within the service cell range of the second network device. The flying terminal can send a measurement report to the second network device when the reference signal received power (RSRP) is less than a preset threshold. After receiving the measurement report, the second network device transmits it to the first network device. In this way, even if the flying terminal is not within the service cell range of the first network device, the first network device can still receive the measurement report of the flying terminal sent by the second network device to adjust the beam emission direction, thereby improving the flexibility of the beam emission direction adjustment.

[0078] See Figure 2 , Figure 2 is a flowchart of a beam adjustment method provided by an embodiment of the present application, which is executed by a flying terminal. As Figure 2 shown, the beam adjustment method provided in this embodiment includes the following steps:

[0079] Step 201: Send a measurement report, where the measurement report is used to adjust the beam emission direction of the first network device.

[0080] In one embodiment, the measurement report includes at least one of the following:

[0081] The position of the flying terminal;

[0082] The speed of the flying terminal.

[0083] In one embodiment, the speed of the flying terminal includes a first speed in a first direction, a second speed in a second direction, and a third speed in a third direction, where the first direction, the second direction, and the third direction are perpendicular to each other.

[0084] In one embodiment, sending a measurement report includes:

[0085] Sending a measurement report to a first network device, where the flying terminal is within the serving cell range of the first network device.

[0086] In one embodiment, before sending the measurement report to the first network device, it further includes:

[0087] Receiving a first signaling sent by the first network device when the flying terminal switches to the serving cell of the first network device, where the first signaling is used to instruct the flying terminal to report the measurement report periodically according to a first period.

[0088] In one embodiment, sending a measurement report includes:

[0089] When the reference signal received power (RSRP) of the flying terminal is less than a preset threshold value, sending a measurement report to a second network device, so that the second network device forwards the measurement report to the first network device. The flying terminal is within the serving cell range of the second network device, where the measurement report includes the location of the flying terminal.

[0090] The following uses some specific embodiments to elaborate in detail on the process of the above method.

[0091] First, an introduction to the related technology.

[0092] The design of the active antenna unit (AAU) of the fifth-generation mobile communication (5G) base station aims to cover ground terminals. According to the deployment scenario, the 5G base station coverage types can generally be divided into area coverage and line coverage. In general urban areas, area coverage is adopted. Using 64TR / 32TR devices (which can be understood as 64 / 32-channel devices, T represents transmit, that is, transmit, and R represents receive, that is, receive), the maximum number of beams in the horizontal dimension is 8, each beam is 15°, and the maximum number of beams in the vertical dimension is 4, each beam is 6° (corresponding θ1 can be set to 60° (4 * 15°), θ2 can be set to 30° (2 * 15°)), with a total beam angle of 120°×24°, forming a 120° fan-shaped coverage area with a radius of about 200m, as Figure 3 shown. In special scenarios such as high-speed railways, subways, and highways, line coverage is adopted. Using 8TR devices to transmit a maximum of 2 beams in the horizontal dimension, each beam is 65°, and 1 beam in the vertical dimension, with a beam of 6°, with a total beam angle of 130°×6°, forming a linear coverage of about 400 meters in length, as Figure 4 shown.

[0093] The cellular network designs in the related art are all designed for traditional terminals operating on the ground. Whether the base station provides line coverage or area coverage, it is a two-dimensional coverage method. With the continuous development of drone technology and the rapid expansion of drone application scenarios such as drone delivery, drone logistics, low-altitude inspection, and low-altitude rescue, there is an urgent need for a cellular network to provide communication services for low-altitude terminals such as drones. The biggest difference between low-altitude coverage (generally referring to 100 - 600m) and ground coverage is that low-altitude coverage needs to consider the coverage height, which is three-dimensional coverage, and there are almost no reflective objects in the air. Therefore, the base station beam needs to be aligned with the areas to be covered. Currently, using existing 64TR / 32TR base station equipment to cover in the low-altitude direction, as Figure 5 shown, there will be a problem of low-altitude top holes. The solutions in the related art generally use the sidelobes of the beam for coverage. However, due to the low gain of the sidelobe beam and limited coverage range, there are still relatively large coverage holes. And if a complete 90° coverage in the low-altitude vertical dimension is directly formed by increasing the number of devices, at least 4 64TR / 32TR devices need to be deployed (if 360° omnidirectional low-altitude coverage centered on the base station is required, 4×3 = 12 devices are needed). Deploying so many devices not only has high costs and deployment difficulties, but also has great difficulties in multi-cell interference control and mobility management.

[0094] Therefore, the embodiments of this application propose a low-altitude coverage solution. By combining existing devices and designing the method and information requirements for terminal measurement reporting, an effective 90° coverage in the low-altitude vertical dimension is achieved with as few network devices as possible, solving the problem of low-altitude top coverage holes while reducing equipment costs.

[0095] Limited by the requirements of low-altitude airspace control, the number of low-altitude terminals is limited, and there are often clear flight route plans. Therefore, the requirement for low-altitude coverage is that there is network coverage when there are terminals flying in a specific area, which is different from location coverage. The ground coverage area is fixed, there are many terminals, and the coverage area must maintain network coverage for a long time.

[0096] Based on the above goal of ensuring effective network coverage when low-altitude terminals are flying, the embodiments of this application propose a low-cost low-altitude coverage solution using existing device combinations, solving the problem of no coverage at the low-altitude top while reducing equipment costs. The main implementation solution contents include: (1) Deploy a device that emits a coverage beam upward to fill the vertical dimension coverage hole and achieve coverage at the low-altitude top; (2) By flexibly adjusting the beam emission direction, the network can cover the low-altitude terminal flight area; (3) Design a measurement report for the terminal to report information such as longitude, latitude, altitude, and flight speed, so that the network coverage can be adjusted in real time according to the flight path of the terminal.

[0097] In the solution of this embodiment, a device (corresponding to the above-mentioned first network device) is added to the low-altitude base station tower, which emits beams upward, directs the original horizontal-dimensional beam of the device to the vertical dimension, and fills the vertical-dimensional coverage hole (for example, an 8TR device can achieve 65°×2 vertical-dimensional coverage, and a 64TR / 32TR device can achieve 15°×8 vertical-dimensional coverage). Since the original vertical-dimensional beam width is turned to cover the horizontal dimension, the beam width is only 6° or 24° (8TR device or 64TR device), and the achieved coverage is as Figure 6 shown, and partial coverage is achieved above the top. The added device needs to be able to adjust the horizontal direction angle of beam emission flexibly, and the adjustment range is [0°, 180°]. Considering low cost, it is generally recommended to deploy an 8TR device.

[0098] As Figure 7 shown, the specific steps of the solution of the embodiment of the present application are as follows:

[0099] First, the first network device (for example, Figure 7 the top cell base station therein) sends a measurement configuration (RRCReconfiguration) to the flying terminal (i.e., the low-altitude terminal), including measurement parameters. After receiving the measurement configuration, the flying terminal can measure the measurement parameters configured in the measurement configuration, obtain a measurement report, and report it.

[0100] Table 1

[0101]

[0102] Secondly, when the flying terminal is within the serving cell range of the second network device (for example, Figure 7 the diagonal cell base station therein), if the reference signal received power RSRP of the flying terminal in the serving cell of the second network device is less than a preset threshold value (A2 threshold), then the A2 event is triggered, and a measurement report (Measurement report) is reported to the second network device. The measurement report can include not only the current RSRP (the RSRP in the serving cell of the second network device), but also information such as the longitude, latitude, and altitude of the flying terminal. After receiving the measurement report, the second network device can send the measurement report to the first network device through the Xn interface, and the first network device adjusts the beam emission direction angle in real time according to the information in the measurement report, such as longitude, latitude, and altitude information, to cover the flying direction of the low-altitude terminal. Among them, the fields of the measurement report reported by the low-altitude terminal can be as shown in Table 1.

[0103] It should be noted that for the cell handover of the ground terminal, only the signal level value needs to be judged. Because when the ground coverage is designed, the hanging height of the base station, the antenna downtilt angle, the azimuth angle, etc. have been calculated according to the required covered plane position and covered area. Therefore, the ground terminal handover only needs to be performed according to the relative position of the signal strength without knowing the absolute position of the terminal. In the solution of the embodiment of the present application, when the low-altitude terminal flies to the top cavity part, that is, when it flies to Figure 6 the inner circle edge of cell 1 / 2 / 3 in the middle, it needs to be covered by the top cell 4. Since the coverage range of cell 4 is limited and the coverage range of cell 4 is different at different heights, it is necessary to adjust the beam emission direction angle of cell 4 according to the absolute position of the terminal to perform real-time coverage.

[0104] In addition, generally, the flight terminal will obtain longitude, latitude and altitude information through GPS, barometer, etc. The acquisition of this information is not limited, and only this information needs to be reported to the network at the same time when reporting the measurement report of the serving cell. The base station side also needs to make the same adaptation to be able to parse the longitude, latitude and altitude information reported by the flight terminal.

[0105] Furthermore, in the case where the flight terminal switches to the serving cell of the first network device, the first network device determines the target position according to the initial position when the flight terminal switches to the first network device and information such as the speed of the flight terminal, and adjusts the beam emission direction of the first network device according to the target position:

[0106] Since the coverage range of the top cell (the serving cell of the first network device) is limited, when the low-altitude terminal switches to be covered by the top cell, the top cell needs to know the flight path of the low-altitude terminal to be able to adjust the beam emission direction angle in real time to ensure network coverage of the low-altitude terminal. The flight report (measurement report) designed in the embodiment of the present application includes the speed of the flight terminal in three dimensions to represent the flight path. As shown in Table 2, a total of 24 bit information needs to be reported. Compared with directly reporting the longitude, latitude and altitude information (as shown in Table 1, a total of 51 bit), the consumed overhead is small;

[0107] In addition, it should be noted that when the flying terminal is within the service area of the serving cell of the second network device, after reporting a measurement report on serving cell measurement to the second network device, it can perform co-frequency / heterogeneous frequency measurement. When the received reference signal power (RSRP) in the measurement is greater than a preset handover threshold (A3 / a4 threshold), it reports a co-frequency / heterogeneous frequency measurement report to the second network device, which may include the RSRP of the serving cell of the first network device, etc. When the second network device makes a handover decision and determines to perform cell handover, it sends a handover request to the first network device. In response to the handover request, the first network device returns a handover request acknowledgement. After receiving the handover acknowledgement sent by the first network device, the second network device sends a handover command to the low-altitude terminal. After the RRC connection reconfiguration between the low-altitude terminal and the first network device is completed, it can switch to the serving cell of the first network device. After the flying terminal switches to the serving cell of the first network device, the first network device can send a measurement configuration to the flying terminal and instruct the flying terminal to periodically report measurement reports. The flying terminal can periodically report measurement reports (including the three-dimensional speed of the flying terminal, etc.). For example, the first network device can instruct the terminal to periodically report a flight report through RRC or DCI signaling. The first network device calculates the flight path of the flying terminal based on the flight report and the initial position of the flying terminal during handover, and adjusts the beam emission direction angle to cover the terminal position. It is required that the first network device can calculate the beam emission angle corresponding to the position of the flying terminal, that is, it can select an appropriate beam emission angle according to the flight path of the flying terminal to cover the terminal. In this embodiment, the flying terminal realizes periodic reporting of flight reports and event-triggered reporting of serving cell measurement reports in the top cell. When the first network device adjusts the beam emission angle inaccurately through the flight report, resulting in weak coverage of the terminal, the terminal position can be calibrated in time through the measurement report, and the beam direction can be adjusted according to the received measurement report to achieve accurate coverage over the top sky.

[0109]

[0110] It should be noted that the process of determining the target position of the flying terminal based on the initial position and the speed of the flying terminal is as follows:

[0111] When the flying terminal switches to the top cell, the base station of the top cell (i.e., the first network device) already knows the initial longitude, latitude, and altitude (i.e., the initial position) of the flying terminal, denoted as (A lat , A long , A heig ).

[0112] The flight terminal reports the three-dimensional velocity (V X , V Y , V Z ) of the terminal to the top cell at a period of T milliseconds, with the unit of km / h. The first network device calculates the flight path points of the flight terminal, i.e., the target position (B lat , B long , B heig ) every t seconds (t is an integer multiple of T);

[0113] The first total velocity V X总 (unit: m / s) of the north-south flight velocity (i.e., the first velocity in the first direction) of the flight terminal within t seconds is obtained by the following formula:

[0114] V X总 = (V x1 + V x2 +... + Vx (t / T) ) * 5 / 18;

[0115] Among them, the positive value of V X总 indicates flying north, and the negative value indicates flying south. V xj represents the first velocity reported by the flight terminal in the j-th period, where j is an integer greater than or equal to 1 and less than or equal to t / T.

[0116] Then, the north-south flight distance dx (unit: m) of the terminal can be calculated:

[0117] dx = |V X总 | * t;

[0118] According to the north-south distance latitude change amount formula, the latitude change amount Δ lat (unit: degree) of the flight of the flight terminal is calculated:

[0119] Δ lat = (dx / R) * (180 / π),

[0120] Among them: Δ lat is the latitude change amount, in degrees, and R is the radius of the earth, in meters.

[0121] Based on the positive and negative values of V X总 , the north-south flight direction of the terminal is known. Then, according to whether the first network device is located in the northern or southern hemisphere, it can be determined whether the latitude of the flight terminal increases or decreases after flight. If the first network device is in the northern hemisphere, the latitude increases when the flight terminal flies north and decreases when it flies south; if the first network device is in the southern hemisphere, the latitude decreases when the flight terminal flies north and increases when it flies south;

[0122] Then, the latitude B lat (unit: degree) of the flight terminal after flying for t seconds can be calculated:

[0123] B lat = A lat + Δ lat .

[0124] Similarly, the second total velocity V of the flight terminal in the east-west flight velocity (i.e., the second velocity in the second direction) within t seconds y总 (unit: meters per second) is obtained through the following formula:

[0125] V y总 = (V y1 + V y2 +... + V y(t / T) ) * 5 / 18;

[0126] wherein, V Y总 A positive velocity value indicates flying eastward, and a negative value indicates flying westward. V yj represents the second velocity reported by the flight terminal in the j-th cycle;

[0127] Then, the east-west flight distance dy (unit: meters) of the terminal can be calculated:

[0128] dy = |V Y总 | * t;

[0129] According to the east-west distance longitude change amount formula, the longitude change amount Δ long (unit: degrees) of the flight terminal is calculated:

[0130] Δ long = (dy / (R * cos(A lat ))) * (180 / π),;

[0131] where: Δ long is the longitude change amount, in degrees, and R is the radius of the earth, in meters;

[0132] When the base station is in the eastern hemisphere, the longitude increases when the terminal flies eastward and decreases when it flies westward; when the base station is in the western hemisphere, the longitude decreases when the terminal flies eastward and increases when it flies westward;

[0133] Then, the longitude B long (unit: degrees) of the flight terminal after flying for t seconds can be calculated:

[0134] B long = A long + Δ long .

[0135] Similarly, the third total velocity V of the flight terminal in the up-down flight velocity (i.e., the third velocity in the third direction, which can be understood as the vertical velocity, and up and down should be understood relative to the ground, the direction away from the ground is up, and the direction close to the ground is down) within t seconds z总(The unit is meters per second) is obtained through the following formula:

[0136] V z总 =(V z1 +V z2 +...+V z(t / T) )*5 / 18;

[0137] wherein, for V Z总 a positive speed value indicates flying upward, and a negative value indicates flying downward. V zj represents the third speed reported by the flight terminal in the j-th cycle;

[0138] Then, calculate the height change Δ heig (unit: meters):

[0139] Δ heig =|V z总 |*t;

[0140] Then, the height B heig (unit: meters) of the flight terminal after flying for t seconds can be calculated:

[0141] B heig =A heig +Δ heig .

[0142] As can be seen from the above process, when the flight terminal switches to fly in the top cell (the serving cell of the first network device), the first network device calculates the flight path point position (B lat , B long , B heig ) of the flight terminal every t seconds, and adjusts the beam emission direction angle according to the path point position to provide network coverage. The base station beam forms a coverage area with a certain range, not a single point, and can tolerate the processing delay from the terminal information reporting to the base station calculating the position and forming the beam. And when the terminal is in the top cell and has weak signal coverage due to inaccurate beam coverage, it will report the serving cell measurement report, and the report will carry the terminal's longitude, latitude and height information, which can further calibrate the beam emission direction.

[0143] In addition, it should be noted that the process of determining the beam emission angle according to the target position to adjust the beam emission angle of the first network device is specifically as follows:

[0144] In one example, according to the target location, the preset corresponding relationship can be searched to determine the beam emission angle matching the target location. The preset corresponding relationship is the corresponding relationship between the pre-set location and the beam emission angle, which may include multiple pieces of information. Each piece of information includes a location (which may include altitude, longitude, and latitude, or may also include the relative altitude to the first network device) and the emission angle corresponding to this location. The preset corresponding relationship can be as shown in Table 3;

[0145] Table 3

[0146]

[0147] In another example, according to the target location, the angular range can be calculated, and an angle is selected from the angular range as the beam emission angle. The specific solution is as follows:

[0148] First, according to the longitude and latitude of the terminal (B lat , B long ), the longitude and latitude difference relative to the longitude and latitude of the base station (the first network device) (C lat , C long ) can be calculated:

[0149] Δ’ lat = B lat - C lat ;

[0150] Δ’ long = B long - C long ;

[0151] Then, according to the relationship between the longitude and latitude difference and the relationship between the distance and the longitude and latitude change amount, the terminal coordinates (Bx, By) with the base station as the origin (0, 0) and the beam emission horizontal angle of 0°, that is, the long axis of the beam coverage as the positive half-axis of the X-axis (as shown in Figure 8 ) are obtained:

[0152] Bx = Δ’ lat * R / (180 / π);

[0153] By = Δ’ long * (R * cos(B lat )) / (180 / π);

[0154] Bx is the coordinate component along the x-axis, and By is the coordinate component along the y-axis;

[0155] Then, the beam emission horizontal angle rotates clockwise by θ (in radians) from the positive half-axis of the X-axis, and the coordinates of the terminal (Bx’, By’) can be obtained under the condition that the long axis of the beam coverage is the positive half-axis of the x-axis (as shown in Figure 9 ):

[0156] Bx’ = Bx * cos(θ) + By * sin(θ);

[0157] By’ = -Bx * sin(θ) + By * cos(θ);

[0158] Then, according to the height B of the terminal heig (i.e., H) and the hanging height h of the base station, the major axis radius a = θ1 * (H - h) and the minor axis radius b = θ2 * (H - h) of the ideal elliptical coverage area at the flight height of the terminal can be calculated. For an 8TR device, θ1 can be set to 65°, and θ1 can be set to 3°;

[0159] Finally, according to the calculation formula Bx’ 2 / a 2 +By’ 2 / b 2 ≤1, it can be determined in which coverage area formed by the beam emission direction angle of the terminal, and then the angle range of θ can be determined. Select an angle within the angle range as the beam emission angle, and the base station emits the beam at this beam emission angle to cover the flying terminal.

[0160] In addition, for example, assume that there are two UAV flight paths passing through the top hole area, as Figure 10 shown. Some terminals go from cell 1 to cell 2, and some terminals go from cell 1 to cell 3. First, deploy a first network device (e.g., an 8TR device) that emits an upward beam in the hole area to form a certain network coverage area. When there are terminals flying on both flight paths, calculate the beam emission angles of the base station according to the latitude, longitude, height, and three-dimensional flight speed information reported by the terminals, and then use the time-division method to cover the two flight paths respectively. For example, the beam is directed to flight path 1 in the first 10 ms and to flight path 2 in the next 10 ms, and so on, so as to ensure that the terminals passing through the top hole area can all obtain network services.

[0161] When terminal A on flight path 1 first reaches the edge of cell 1, at this time, terminal A reports its latitude, longitude, height, and RSRP to cell 1. Cell 1 transfers these serving cell measurement information to the top cell 4. Cell 4 calculates whether the coverage area of different beam emission direction angles can cover the terminal path through the latitude, longitude, and height information of terminal A. If not, it means that the terminal path does not pass through cell 4. If it is calculated that there is a coverage area formed by a beam emission direction angle that can cover the terminal, immediately form the corresponding beam for terminal A to switch;

[0162] After a period of time, terminal B on flight route 2 also reaches the edge of cell 1. At this time, cell 4 obtains the flight path information of both terminals simultaneously and needs to calculate the beam emission direction angles for covering both terminals. If there is exactly one angle among 120 beam emission direction angles that can cover both terminals simultaneously, the corresponding beam is immediately formed. If the two terminals require the base station to cover them with two different beam emission directions, they are covered separately by means of time division.

[0163] If there are multiple terminals in the upper airspace, the beam emission direction angles required for multiple terminals can also be calculated. Multiple terminals that can be covered by one beam are grouped into a cluster, and time division coverage is performed in units of clusters.

[0164] Through the solution of this embodiment, the problem of coverage holes existing in the upper airspace due to fixed coverage by the base station side lobe can be solved. The solution flexibly adjusts the coverage direction according to the terminal flight path to achieve precise coverage. It can solve the problems of high cost, difficult deployment, difficult cell interference control and mobility management in the existing method of deploying multiple sets of AAUs to make up for coverage holes. This solution realizes low-cost, simple deployment and simple management of low-altitude coverage through a set of equipment and information interaction between equipment. This solution designs a low-overhead terminal flight path reporting method, which jointly represents the terminal flight path through periodic terminal three-dimensional flight speed information and event-based terminal longitude, latitude and altitude information. The periodic flight report has low overhead, while the more expensive serving cell measurement report is reported event-based, minimizing the overhead of the terminal reporting the flight path as much as possible.
