[0021] In a first aspect, referring to FIG. 1 , an embodiment of the present application provides a low-altitude coverage mobility management method, which may include steps 100 and 101 .

[0022] In step 100, the flight path information of the aircraft is determined based on the service characteristic information of the aircraft and a pre-constructed three-dimensional low-altitude performance matrix; wherein the flight path information includes the position information of the aircraft in the three-dimensional low-altitude grid space at different times.

[0023] In some exemplary embodiments, an aircraft refers to various devices that need to communicate and can fly in the atmosphere or in outer space. For example, an aircraft may include but is not limited to an airplane, a helicopter, a rocket, a drone, a spacecraft, etc.

[0024] In some exemplary embodiments, the three-dimensional low-altitude grid space is obtained by gridding the three-dimensional low-altitude space.

[0025] In some exemplary embodiments, the three-dimensional low-altitude space refers to a three-dimensional space with an altitude lower than a preset altitude, corresponding to a longitude range in the longitude direction, a latitude range in the latitude direction, and an altitude range in the altitude direction.

[0026] In some exemplary embodiments, the longitude range and the latitude range may generally be divided according to actual needs, and the altitude range may be the portion below a preset altitude.

[0027] In some exemplary embodiments, the preset altitude may be 3000 meters.

[0028] In some exemplary embodiments, each three-dimensional low-altitude grid space can be viewed as a cube, corresponding to longitude information, latitude information, and altitude information. In other words, the three-dimensional low-altitude grid space can be obtained by dividing the three-dimensional low-altitude space along the longitude direction, latitude direction, and altitude direction.

[0029] In some exemplary embodiments, an element value in the three-dimensional low-altitude performance matrix includes a mobile communication performance indicator of a corresponding three-dimensional low-altitude grid space.

[0030] In some exemplary embodiments, the service characteristic information of the aircraft includes at least one of the following: target MCS, target uplink rate, target downlink rate, target latency, geographic location information of the flight starting point, geographic location information of the flight end point, target reference signal received power (RSRP, Reference Signal Received Power), target signal to interference plus noise ratio (SINR, Signal to Interference plus Noise Ratio), and target reliability.

[0037] In some exemplary embodiments, the mobile network busyness level can be divided according to actual needs and the level can be divided according to the busyness of the mobile network. For example, it can be divided into four levels, level 1 indicates that the mobile network is idle (for example, the wireless resource utilization of the mobile network is between 0% and 30%), level 2 indicates that the mobile network is a bit busy (for example, the wireless resource utilization of the mobile network is between 30% and 50%), level 3 indicates that the mobile network is very busy (for example, the wireless resource utilization of the mobile network is between 50% and 80%), and level 4 indicates that the mobile network is congested (for example, the wireless resource utilization of the mobile network is between 90% and 100%). Here, the wireless resource utilization of the mobile network can be the wireless channel resource utilization, or it can be other indicators that can characterize the busyness of the network, and this disclosure does not specifically limit it.

[0045] In some exemplary embodiments, the three-dimensional low-altitude performance matrix may be updated when the mobile networking information changes.

[0046] In some exemplary embodiments, when updating the three-dimensional low-altitude performance matrix, it is necessary to redetermine the MCS of the three-dimensional low-altitude grid space; redetermine the mobile communication performance index of the three-dimensional low-altitude grid space based on the MCS of the three-dimensional low-altitude grid space; and update the three-dimensional low-altitude performance matrix based on the redetermined mobile communication performance index of the three-dimensional low-altitude grid space.

[0047] In some exemplary embodiments, updating the three-dimensional low-altitude performance matrix based on the re-determined mobile communication performance index of the three-dimensional low-altitude grid space includes: using the re-determined mobile communication performance index of the three-dimensional low-altitude network space as the element value of the three-dimensional low-altitude grid space in the updated three-dimensional low-altitude performance matrix.

[0049] In some exemplary embodiments, determining the geographic location information of the i+1th three-dimensional low-altitude grid space in the flight path information based on the service characteristic information of the aircraft and the mobile communication performance indicators of the three-dimensional low-altitude grid space adjacent to the i-th three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix includes: determining the geographic location information of the i+1th three-dimensional low-altitude grid space in the flight path information based on the service characteristic information of the aircraft and the mobile communication performance indicators of the three-dimensional low-altitude grid space adjacent to the i-th three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix, measurement time and current mobile network busy level information.

[0050] In some exemplary embodiments, determining the geographic location information of the i+1th three-dimensional low-altitude grid space in the flight path information based on the service characteristic information of the aircraft and the mobile communication performance index, measurement time and current mobile network busy level information of the three-dimensional low-altitude grid space adjacent to the i-th three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix includes: selecting a target three-dimensional low-altitude grid space from the three-dimensional low-altitude grid space adjacent to the i-th three-dimensional low-altitude grid space; wherein the measurement time in the element value corresponding to the target three-dimensional low-altitude grid space matches the target flight time of the aircraft, and the current mobile network busy level information is higher than the mobile communication performance index of the preset busy level information is higher than the service characteristic information, and the target three-dimensional low-altitude grid space is different from the i-1th three-dimensional low-altitude grid space; and selecting the optimal three-dimensional low-altitude grid space from the target three-dimensional low-altitude grid space as the i+1th three-dimensional low-altitude grid space.

[0051] In one example, the current mobile network busy level information indicates busy level 4 (for example, the mobile network is congested), and the preset busy level information indicates busy level 2 (for example, the mobile network is a bit busy), then the current mobile network busy level information is higher than the preset busy level information.

[0052] In some exemplary embodiments, matching the measured time with the target flight time of the aircraft may mean that the measured time and the target flight time are both at the same time within a preset time range. For example, if the preset time range is morning, noon, or evening, and the measured time is in the morning and the target flight time is also in the morning, then the measured time may be considered to match the target flight time of the aircraft.

[0053] In some exemplary embodiments, the mobile network busyness levels may be divided according to actual needs.

[0054] In some exemplary embodiments, the mobile communication performance indicator being higher than the service feature information may mean that the MCS is not lower than the target MCS in the service feature information.

[0058] In some exemplary embodiments, the mobile communication performance indicator being higher than the service feature information may mean that the RSRP is not lower than the target RSRP in the service feature information.

[0059] In some exemplary embodiments, the mobile communication performance indicator being higher than the service feature information may mean that the SINR is not lower than the target SINR in the service feature information.

[0060] In some exemplary embodiments, selecting the optimal three-dimensional low-altitude grid space from the target three-dimensional low-altitude grid space as the i+1th three-dimensional low-altitude grid space includes: determining the comprehensive mobile communication performance index corresponding to each target three-dimensional low-altitude grid space respectively; and selecting the three-dimensional low-altitude grid space with the highest corresponding comprehensive mobile communication performance index from the target three-dimensional low-altitude grid space as the i+1th three-dimensional low-altitude grid space.

[0061] In some exemplary embodiments, respectively determining the comprehensive mobile communication performance indicator corresponding to each target three-dimensional low-altitude grid space includes: for each target three-dimensional low-altitude grid space, selecting a mobile communication performance indicator whose measurement time matches the target flight time of the aircraft from the element values ​​of the target three-dimensional low-altitude grid space; and determining the comprehensive mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space based on the selected mobile communication performance indicator.

[0062] In some exemplary embodiments, determining the comprehensive mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space based on the selected mobile communication performance indicator includes: determining a first intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space based on the selected mobile communication performance indicator and the corresponding measurement time; determining a second intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space based on the selected mobile communication performance indicator and the corresponding mobile network busy level information; and determining the comprehensive mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space based on the first intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space and the second intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space.

[0063] In some exemplary embodiments, determining the first intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space based on the selected mobile communication performance indicator and the corresponding measurement time includes: determining the first intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space as the weighted average of the selected mobile communication performance indicators in the element values ​​of the target three-dimensional low-altitude grid space; wherein the weight of the mobile communication performance indicator is determined according to the corresponding measurement time.

[0064] For example, if the measurement time is in the first week of a month, the weight of the mobile communication performance indicator is W1; if the measurement time is in the second week of a month, the weight of the mobile communication performance indicator is W2; if the measurement time is in the third week of a month, the weight of the mobile communication performance indicator is W3; if the measurement time is in the fourth week of a month, the weight of the mobile communication performance indicator is W4.

[0065] In some exemplary embodiments, determining the second intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space based on the selected mobile communication performance indicator and the corresponding mobile network busy level information includes: determining the second intermediate mobile communication performance indicator corresponding to the target three-dimensional low-altitude grid space as the weighted average of the selected mobile communication performance indicators in the element values ​​of the target three-dimensional low-altitude grid space; wherein the weight of the mobile communication performance indicator is determined according to the corresponding mobile network busy level information.

[0066] For example, if the mobile network busy level information is busy level 1, the weight of the mobile communication performance indicator is W5; if the mobile network busy level information is busy level 2, the weight of the mobile communication performance indicator is W6; if the mobile network busy level information is busy level 3, the weight of the mobile communication performance indicator is W7; if the mobile network busy level information is busy level 4, the weight of the mobile communication performance indicator is W8.

[0068] In some exemplary embodiments, after determining the flight path information of the aircraft based on the business characteristic information of the aircraft and a pre-constructed three-dimensional low-altitude performance matrix, the method further includes: determining whether the reliability of the flight path meets the target reliability in the business characteristic information; if the reliability of the flight path meets the target reliability in the business characteristic information, continuing to execute step 101; if the reliability of the flight path does not meet the target reliability in the business characteristic information, re-executing the step of determining the flight path information of the aircraft based on the business characteristic information of the aircraft and a pre-constructed three-dimensional low-altitude performance matrix until the reliability of the flight path meets the target reliability in the business characteristic information.

[0069] In some exemplary embodiments, the flight path determined when re-performing the step of determining the flight path information of the aircraft based on the traffic characteristic information of the aircraft and the pre-constructed three-dimensional low-altitude performance matrix should be different from the previously determined flight path.

[0070] In some exemplary embodiments, the reliability of the flight path can be determined based on the mobile communication performance indicators of all three-dimensional low-altitude grid spaces that the flight path passes through when determining the flight path and the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft during the flight along the flight path.

[0071] In some exemplary embodiments, the reliability of a flight path may refer to a ratio of the number of flights that meet the conditions to the total number of flights.

[0072] In some exemplary embodiments, a flight that meets the conditions means that the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft during the performance of the flight mission based on the flight path is not lower than the mobile communication performance indicators of all three-dimensional low-altitude grid spaces passed by the flight path when the flight path is in flight.

[0073] For example, the MCS in the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft during the execution of the flight mission based on the flight path is not lower than the MCS in the mobile communication performance indicators of all three-dimensional low-altitude grid spaces passed by the flight path during the flight path.

[0074] The uplink rate in the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft during the performance of the flight mission based on the flight path is greater than or equal to the uplink rate in the mobile communication performance indicator of all three-dimensional low-altitude grid spaces passed by the flight path.

[0075] When the aircraft performs a flight mission based on the flight path, the downlink rate in the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft is greater than or equal to the downlink rate in the mobile communication performance indicator of all three-dimensional low-altitude grid spaces passed by the flight path.

[0076] The delay in the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft during the execution of the flight mission based on the flight path is less than or equal to the delay in the mobile communication performance indicators of all three-dimensional low-altitude grid spaces passed by the flight path.

[0077] When the aircraft performs a flight mission based on the flight path, the RSRP in the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft is greater than or equal to the RSRP in the mobile communication performance indicators of all three-dimensional low-altitude grid spaces passed by the flight path.

[0078] When the aircraft performs a flight mission based on the flight path, the SINR in the measurement data corresponding to all three-dimensional low-altitude grid spaces passed by the flight path reported by the aircraft is greater than or equal to the SINR in the mobile communication performance index of all three-dimensional low-altitude grid spaces passed by the flight path.

[0079] In step 101 , flight path information is sent to an aircraft so that the aircraft performs a flight mission based on the flight path information.

[0080] In some exemplary embodiments, the flight path information may also be sent to an aircraft controller so that the aircraft controller controls the aircraft to perform a flight mission based on the flight path information.

[0081] In some exemplary embodiments, flight path information may be sent directly to the aircraft or an aircraft controller.

[0082] In some exemplary embodiments, the flight path information may be sent to the aircraft or the aircraft controller via an aircraft cloud control server.

[0083] In some exemplary embodiments, after transmitting flight path information to an aircraft so that the aircraft executes a flight mission based on the flight path information, the method further includes: receiving measurement data corresponding to all three-dimensional low-altitude grid spaces on the flight path reported by the aircraft during the flight mission; and updating, for each three-dimensional low-altitude grid space on the flight path, the element value corresponding to the three-dimensional low-altitude grid space in a three-dimensional low-altitude performance matrix based on the measurement data corresponding to the three-dimensional low-altitude grid space. In other words, for each three-dimensional low-altitude grid space on the flight path, the element value corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix is ​​updated based on the measurement data corresponding to the three-dimensional low-altitude grid space.

[0084] In some exemplary embodiments, the measurement data includes at least one of the following: uplink rate, downlink rate, latency, flight geographic location information, reference signal received power, and signal-to-noise ratio.

[0085] In some exemplary embodiments, when the aircraft is performing a flight mission, the measurement data corresponding to all three-dimensional low-altitude grid spaces on the reported flight path may also be reported by the aircraft controller controlling the aircraft.

[0086] In some exemplary embodiments, receiving measurement data corresponding to all three-dimensional low-altitude grid spaces on a flight path reported by an aircraft during the performance of a flight mission includes: receiving measurement data corresponding to all three-dimensional low-altitude grid spaces on a flight path reported by an aircraft of a preset type during the performance of a flight mission.

[0087] In some exemplary embodiments, updating the element values ​​corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix based on the measurement data corresponding to the three-dimensional low-altitude grid space includes: adding the mobile communication performance indicators, measurement time and mobile network busy level information determined based on the measurement data corresponding to the three-dimensional low-altitude grid space to the element values ​​corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix; and deleting the mobile communication performance indicators whose measurement time is outside the preset time range in the element values ​​corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix.

[0088] In some exemplary embodiments, updating the element values ​​corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix according to the measurement data corresponding to the three-dimensional low-altitude grid space includes: determining the MCS corresponding to the measurement data according to the measurement data corresponding to the three-dimensional low-altitude grid space, adding the MCS corresponding to the measurement data, the measurement time and the mobile network busy level information to the element values ​​corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix; deleting the MCS whose measurement time is outside the preset time range in the element values ​​corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix.

[0089] In some exemplary embodiments, the MCS corresponding to the measurement data may be determined according to a mapping relationship between the MCS and a mobile communication performance indicator.

[0090] The low-altitude coverage mobility management method provided in the embodiment of the present application satisfies the business requirements of the aircraft by obtaining the flight path information of the aircraft based on the business characteristic information of the aircraft and the three-dimensional low-altitude performance matrix, allowing the aircraft to fly within a three-dimensional low-altitude grid space that meets the business requirements, thereby improving the low-altitude coverage mobility performance and reducing low-altitude interference.

[0091] In order to better present the low-altitude coverage mobility management method of the embodiment of the present application, two examples are listed below for illustration. The listed examples are not used to limit the protection scope of the embodiment of the present application.

[0092] Example 1

[0093] As shown in FIG. 2 , the low-altitude coverage mobility management method of this example may include steps 200 to 206 .

[0094] In step 200, for each three-dimensional low-altitude grid space in the three-dimensional low-altitude space, the base station determines the MCS of the three-dimensional low-altitude grid space; the base station determines the mobile communication performance index of the three-dimensional low-altitude grid space based on the MCS of the three-dimensional low-altitude grid space; the base station uses the mobile communication performance index of the three-dimensional low-altitude grid space as the element value corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix, thereby obtaining a constructed three-dimensional low-altitude performance matrix.

[0095] In this example, the mobile communication performance indicators include: uplink rate, downlink rate, latency, and geographic location information.

[0096] In step 201 , the base station determines the flight path information of the aircraft based on the service characteristic information of the aircraft and a pre-built three-dimensional low-altitude performance matrix.

[0097] In this example, the service characteristic information includes: target uplink rate, target downlink rate, target delay, and target reliability.

[0098] In step 202, the base station determines whether the reliability of the flight path meets the target reliability. If the reliability of the flight path meets the target reliability, step 203 is continued; if the reliability of the flight path does not meet the target reliability, step 201 is continued.

[0099] In step 203, the base station sends the flight path information to the aircraft cloud control server.

[0100] In step 204 , the aircraft cloud control server sends the flight path information to the aircraft, so that the aircraft performs the flight mission based on the flight path information.

[0101] In step 205 , the aircraft obtains measurement data corresponding to all three-dimensional low-altitude grid spaces on the flight path during the execution of the flight mission, and reports the measurement data to the base station.

[0102] In this example, the measured data includes: uplink rate, downlink rate, and latency.

[0103] In step 206 , the base station adds the measurement data, measurement time, and mobile network busy level information reported by the aircraft to the element value corresponding to the corresponding three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix.

[0104] Example 2

[0105] As shown in FIG3 , the low-altitude coverage mobility management method of this example may include steps 300 to 306 .

[0106] In step 300, for each three-dimensional low-altitude grid space in the three-dimensional low-altitude space, the base station determines the MCS of the three-dimensional low-altitude grid space; the base station determines the mobile communication performance index of the three-dimensional low-altitude grid space based on the MCS of the three-dimensional low-altitude grid space; the base station uses the mobile communication performance index of the three-dimensional low-altitude grid space as the element value corresponding to the three-dimensional low-altitude grid space in the three-dimensional low-altitude performance matrix, thereby obtaining a constructed three-dimensional low-altitude performance matrix.

[0107] In this example, the mobile communication performance indicators include: uplink rate, downlink rate, latency, and geographic location information.

[0108] In step 301 , the base station determines the flight path information of the aircraft based on the service characteristic information of the aircraft and a pre-built three-dimensional low-altitude performance matrix.

[0109] In this example, the service characteristic information includes: target uplink rate, target downlink rate, target delay, and target reliability.

[0110] In step 302, the base station determines whether the reliability of the flight path meets the target reliability.
