Description

Technical Field

[0001] This disclosure relates to the field of communications, and in particular to information transmission methods and apparatus, and storage media. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. The term "UAV" is actually a general term for unmanned aerial vehicles, which, from a technical perspective, can be categorized as: unmanned fixed-wing aircraft, unmanned vertical takeoff and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders, among others.

[0003] With the rapid development of drone technology, the reduction in cost, and the improvement of functions, drones are increasingly being used by ordinary consumers. However, the real essential need for drones lies in industry applications. Currently, applications in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romantic moments have greatly expanded the uses of drones. Various countries are actively expanding industry applications and developing drone technology.

[0004] To further expand the application scope of drones, the 3rd Generation Partnership Project (3GPP) approved the "Enhanced Support for Aerial Vehicles" project. This aims to research and standardize how cellular networks can provide services that meet the needs of drones.

[0005] There are generally two modes of drone flight. One is fixed mode, where the operator plans the drone's flight path on the controller, and the drone flies along the planned route without the controller needing to constantly monitor it. The other is dynamic mode, where the operator remotely controls the drone in real time via the controller. In fixed mode, because the drone's flight path and trajectory are fixed, the cellular network can predict which cellular base stations the drone will pass through.

[0006] Typically, the path information of a drone is constructed from multiple waypoints along its flight path. How the drone selects which waypoints to report is a problem that urgently needs to be solved. Summary of the Invention

[0139] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0140] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of at least one associated listed item.

[0141] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0142] The information transmission method provided in this disclosure will be introduced from the perspective of the UAV.

[0143] This disclosure provides an information transmission method, referring to... Figure 1 As shown, Figure 1 This is a flowchart illustrating an information transmission method according to an embodiment, which can be applied to unmanned aerial vehicles (UAVs). The method may include the following steps:

[0144] In step 101, configuration information sent by the base station is received.

[0145] In this embodiment of the disclosure, the configuration information includes the maximum number of path points allowed to be reported by the drone and at least one of the first methods.

[0146] The first method involves the drone selecting the target path point that needs to be reported to the base station when the total number of path points stored in the drone is greater than the maximum number of path points.

[0147] In one possible implementation, the configuration information sent by the base station includes the maximum number of path points.

[0148] In another possible implementation, the configuration information sent by the base station includes the first method.

[0149] In another possible implementation, the configuration information sent by the base station includes the maximum number of path points and the first mode.

[0150] In step 102, if the total number of path points is greater than the maximum number of path points, the target path point is selected on the flight path of the UAV.

[0151] In one possible implementation, the configuration information sent by the base station does not include the maximum number of path points. In this case, the UAV can determine the maximum number of path points based on the protocol agreement or other methods. This disclosure does not limit this.

[0152] In this embodiment of the disclosure, if the total number of path points stored by the UAV is greater than the maximum number of path points, the UAV can select target path points that need to be reported to the base station on its own flight path. The total number of target path points is less than or equal to the maximum number of path points configured by the base station for the UAV.

[0153] In step 103, the flight path information corresponding to the target waypoint is reported to the base station.

[0154] It should be understood that when the total number of pathpoints is less than or equal to the maximum number of pathpoints, the UAV can report all the flight path information corresponding to the stored total pathpoints to the base station without selecting a target pathpoint from the total pathpoints for reporting. Of course, when the total number of pathpoints is less than or equal to the maximum number of pathpoints, it is also possible to select the target pathpoint that needs to be reported to the base station and report its corresponding flight path information to the base station, and this disclosure does not limit this.

[0155] The above embodiments improve the efficiency of drones reporting flight path information and enhance usability.

[0156] In some alternative embodiments, the first method is any of the following: selecting the target path points in a first order; selecting the target path points according to a first distribution rule of path points; selecting the target path points according to a first distance value and / or a second distance value; or selecting the target path points by a drone.

[0157] The first order can be from the start point to the end point of the flight path, or from the end point to the start point, or from any reference path point to another reference path point; this disclosure does not limit this.

[0158] The first distribution rule refers to the rule for the distribution of path points. Optionally, the first distribution rule is used to indicate at least one reference path point and a specified number. The reference path point is at least one of the following: the starting point of the UAV's flight path; the ending point of the UAV's flight path; the center point of the UAV's flight path. This disclosure does not limit the setting of the reference path point. The specified number is used to indicate the number of path points selected by the UAV when selecting a target path point based on the reference path points.

[0159] Wherein, the first distance value is the distance between a path point on the flight path and the base station, and the second distance value is the distance between a path point on the flight path and a neighboring base station of the base station.

[0160] Among them, "selecting target path points by drones" means that the drones select target path points based on their own implementation methods.

[0161] In some alternative embodiments, when the configuration information includes the first approach, refer to Figure 2 As shown, Figure 2 This is a flowchart illustrating an information transmission method according to an embodiment, which can be applied to unmanned aerial vehicles (UAVs). The method may include the following steps:

[0162] In step 201, configuration information sent by the base station is received.

[0163] In this embodiment of the disclosure, the configuration information includes at least a first mode, wherein the first mode is a mode in which the drone selects the target path point to be reported to the base station when the total number of path points stored by the drone is greater than the maximum number of path points.

[0164] In step 202, if the total number of path points is greater than the maximum number of path points, the target path point is selected on the flight path of the UAV based on the first method.

[0165] In this embodiment of the disclosure, if the total number of path points stored by the UAV is greater than the maximum number of path points configured by the base station for the UAV, the UAV can select a target path point to be reported to the base station on its own flight path, based on the first method configured by the base station. The total number of target path points is less than or equal to the maximum number of path points. In step 203, the flight path information corresponding to the target path point is reported to the base station.

[0166] It should be understood that when the total number of path points is less than or equal to the maximum number of path points, the UAV can report all the flight path information corresponding to the stored total path points to the base station without selecting a target path point from the total path points for reporting. Of course, when the total number of path points is less than or equal to the maximum number of path points, it is also possible to select the target path point that needs to be reported to the base station and report its corresponding flight path information to the base station based on the first method configured by the base station, and this disclosure does not limit this.

[0167] In the above embodiments, when the total number of path points stored by the UAV exceeds the maximum number of path points allowed for the UAV to report, the UAV can select the target path point to be reported to the base station based on the first method included in the configuration information. Furthermore, the UAV reports the flight path information corresponding to the target path point to the base station. This improves the efficiency of the UAV reporting flight path information and ensures high availability.

[0168] In one possible implementation, the first approach is to select the target path points in a first order, which can be from the start point to the end point of the flight path or from the end point to the start point. Accordingly, the UAV can select path points whose total number is less than or equal to the maximum number of path points as target path points in the first order.

[0169] For example, the first order is the order from the start point to the end point of the flight path, and the maximum number of path points is N. The drone can select N path points sequentially from the start point as target path points.

[0170] In another possible implementation, the first approach is to select the target path points according to the first distribution rule. Optionally, the first distribution rule is used to indicate at least one reference path point and a specified number. The reference path point can be the start point, end point, center point, or other reference point on the UAV's flight path; this disclosure does not limit this.

[0171] In this embodiment of the disclosure, the UAV can select a specified number of path points from each of the reference path points and the path points adjacent to each of the reference path points, and use the selected path points as target path points.

[0172] For example, if the reference path points include the start point, the end point, and the center point, and the specified number is 2, then the UAV can select 2 path points at the start point, the end point, and the center point of the flight path, and use the selected 6 path points as the target path points.

[0173] In another possible implementation, the first approach is to select the target path point according to the coverage of the base station and / or its neighboring base stations.

[0174] In this embodiment of the disclosure, the drone can use a waypoint located at the edge of the base station's coverage area as a target waypoint. The base station is either the currently serving base station or the base station where the drone is stationed.

[0175] Specifically, the drone can select a path point whose first distance value is greater than or equal to a first distance threshold as the target path point. Here, the first distance value is the distance between a path point on the drone's flight path and the base station, and the first distance threshold can be configured by the base station or agreed upon by a protocol; this disclosure does not limit this.

[0176] Specifically, the UAV can also use signal strength as a condition for selecting a target path point. Optionally, a path point with a first signal strength less than or equal to a first signal threshold can be selected as the target path point. The first signal strength is the signal strength of the reference signal received by the UAV from the base station. The first signal threshold can be configured by the base station or agreed upon by the protocol, and this disclosure does not limit it.

[0177] In this embodiment of the disclosure, the drone can select a path point located within the coverage area of ​​a neighboring base station as the target path point.

[0178] Specifically, the UAV can select a path point whose second distance value is less than or equal to a second distance threshold as the target path point. The second distance value is the distance between a path point on the UAV's flight path and the neighboring base station. The second distance threshold can be configured by the base station or agreed upon by a protocol; this disclosure does not limit this.

[0179] Specifically, the drone can also use signal strength as a condition for selecting a target path point. A path point with a second signal strength greater than or equal to a second signal threshold is selected as the target path point. The second signal strength is the signal strength of the reference signal received by the drone from the neighboring base station. The second signal threshold can be configured by the base station or agreed upon by the protocol; this disclosure does not limit this.

[0180] In this embodiment of the disclosure, the drone can select path points whose first distance value is greater than or equal to a first distance threshold, and select path points whose second distance value is less than or equal to a second distance threshold, and use all selected path points as target path points.

[0181] In this embodiment of the disclosure, the UAV may also select path points where the first signal strength is less than or equal to the first signal threshold, and select path points where the second signal strength is greater than or equal to the second signal threshold, and use all selected path points as target path points.

[0182] In this embodiment of the disclosure, the drone can also select a target path point based on both distance and signal strength.

[0183] In another possible implementation, the first approach involves the drone selecting the target waypoint. Alternatively, the drone can use a waypoint selected in a second approach as the target waypoint.

[0184] In this embodiment of the disclosure, the second method is any one of the following: selecting the target path point in a second order; selecting the target path point according to a second distribution rule of path points; or selecting the target path point according to the coverage of the base station and / or the neighboring base stations of the base station.

[0185] The second order may be the same as or different from the first order, and this disclosure does not limit this. That is, the UAV may select path points whose total number is less than or equal to the maximum number of path points as target path points according to the second order.

[0186] The second distribution rule may be the same as or different from the first distribution rule described above. Specifically, the UAV determines at least one reference pathpoint and a specified number of pathpoints, and selects the specified number of pathpoints from each reference pathpoint and its adjacent pathpoints, using these selected pathpoints as the target pathpoints. The specific implementation is similar to selecting target pathpoints according to the first distribution rule, and will not be elaborated further here.

[0187] The drone may select a path point located at the edge of the coverage area of ​​the base station as the target path point, and / or select a path point located within the coverage area of ​​a neighboring base station as the target path point.

[0188] Specifically, the UAV can select a path point with a first distance value greater than or equal to a first distance threshold, and / or a path point with a first signal strength less than or equal to a first signal threshold as a target path point. Here, the first distance value is the distance between a path point on the UAV's flight path and the base station, and the first signal strength is the signal strength of the reference signal received by the UAV from the base station. The first distance threshold and the first signal threshold can be configured by the base station or agreed upon by a protocol; this disclosure does not limit their specificity.

[0189] And / or, the UAV may select a path point with a second distance value less than or equal to a second distance threshold, and / or, a path point with a second signal strength less than or equal to a second signal threshold, as the target path point. Wherein, the second distance value is the distance between a path point on the UAV's flight path and the neighboring base station, and the second signal strength is the signal strength of the reference signal received by the UAV from the neighboring base station. The second distance threshold and the second signal threshold may be configured by the base station or agreed upon by a protocol, and this disclosure does not limit them.

[0190] The specific implementation method is similar to the method of selecting target path points according to the coverage of the base station and / or neighboring base stations in the above embodiments, and will not be described again here.

[0191] In the above embodiments, when the total number of path points stored by the UAV exceeds the maximum number of path points allowed for the UAV to report, the UAV can select a target path point based on the first method included in the configuration information sent by the base station. Furthermore, the UAV reports the flight path information corresponding to the target path point to the base station. This improves the efficiency of the UAV reporting flight path information and ensures high availability.

[0192] In some alternative embodiments, where the configuration information does not include the first approach, refer to Figure 3 As shown, Figure 3 This is a flowchart illustrating an information transmission method according to an embodiment, which can be applied to unmanned aerial vehicles (UAVs). The method may include the following steps:

[0193] In step 301, configuration information sent by the base station is received.

[0194] In this embodiment of the disclosure, the configuration information may include the maximum number of path points.

[0195] In step 302, if the total number of path points is greater than the maximum number of path points, the target path point is selected on the flight path of the UAV based on the second method.

[0196] In this embodiment of the disclosure, if the total number of path points stored by the UAV is greater than the maximum number of path points configured by the base station for the UAV, the UAV can select the target path points to be reported to the base station on its own flight path, based on its own implementation, i.e., based on the second method. The total number of target path points is less than or equal to the maximum number of path points.

[0197] In one possible implementation, the second approach is any of the following: selecting the target path points according to a second order; selecting the target path points according to a second distribution rule of path points; or selecting the target path points according to the coverage of the base station and / or the neighboring base stations of the base station.

[0198] The method by which the UAV selects the target path point based on the second method is similar to the method in the above embodiment, and will not be described again here.

[0199] In step 303, the flight path information corresponding to the target waypoint is reported to the base station.

[0200] It should be understood that when the total number of path points is less than or equal to the maximum number of path points, the UAV can report all the flight path information corresponding to the stored total path points to the base station without selecting a target path point from the total path points for reporting. Of course, when the total number of path points is less than or equal to the maximum number of path points, it is also possible for the UAV to select the target path point that needs to be reported to the base station and report its corresponding flight path information to the base station based on the second method, and this disclosure does not limit this.

[0201] In the above embodiments, when the total number of path points stored by the UAV exceeds the maximum number of path points allowed for the UAV to report, the UAV can select the target path point to be reported to the base station based on its own implementation method. Furthermore, the UAV reports the flight path information corresponding to the target path point to the base station. This improves the efficiency of the UAV reporting flight path information and ensures high availability.

[0202] In some alternative embodiments, refer to Figure 4 As shown, Figure 4 This is a flowchart illustrating an information transmission method according to an embodiment, which can be applied to unmanned aerial vehicles (UAVs). The method may include the following steps:

[0203] In step 401, the configuration information sent by the base station through the first Radio Resource Control (RRC) signaling is received.

[0204] In the embodiments disclosed herein, the first RRC signaling may reuse existing RRC signaling in the protocol, or it may be a newly defined RRC signaling in the protocol. This disclosure does not limit this.

[0205] In one possible implementation, if the first RRC signaling is an existing RRC signaling in the first RRC signaling multiplexing protocol, the first RRC signaling can be a UE Information Request signaling.

[0206] In step 402, if the total number of path points is greater than the maximum number of path points, the target path point is selected on the flight path of the UAV.

[0207] In step 403, the flight path information corresponding to the target waypoint is reported to the base station.

[0208] When the configuration information includes the first method, the implementation of steps 402 to 403 is similar to that of steps 202 to 203. When the configuration information does not include the first method, the implementation of steps 402 to 403 is similar to that of steps 302 to 303. These will not be described again here.

[0209] It should be understood that when the total number of path points is less than or equal to the maximum number of path points, the UAV can report all flight path information corresponding to the stored total path points to the base station without selecting target path points from the total path points for reporting. Of course, when the total number of path points is less than or equal to the maximum number of path points, it is also possible for the UAV to select target path points to be reported to the base station based on the first method configured by the base station or the second method autonomously selected by the UAV and report their corresponding flight path information to the base station; this disclosure does not limit this. In the above embodiments, the UAV can receive configuration information sent by the base station through the first RRC signaling. When the total number of path points stored by the UAV is greater than the maximum number of path points allowed for the UAV to report, the UAV can select target path points to be reported to the base station on its flight path, and the total number of selected target path points is less than or equal to the maximum number of path points. Further, the UAV reports the flight path information corresponding to the target path points to the base station. This improves the efficiency of the UAV reporting flight path information and increases availability.

[0210] In some alternative embodiments, the drone may receive the configuration information sent by the base station through a first information unit in a first RRC signaling.

[0211] In the embodiments disclosed herein, the first RRC signaling may reuse an existing RRC signaling in the protocol, or it may be a newly defined RRC signaling in the protocol; this disclosure does not limit this. The first information unit may reuse an existing information unit in an existing RRC signaling, or it may be a newly defined information unit in an existing RRC signaling, or it may be a newly defined information unit in a newly defined RRC signaling; this disclosure does not limit this.

[0212] In one possible implementation, if the first RRC signaling reuses existing RRC signaling in the first RRC signaling multiplexing protocol, and the first information unit reuses existing information units in the first RRC signaling, the first RRC signaling can be UEInformationRequest signaling, and the first information unit can be the FlightPathInfoReportConfig information unit in the UEInformationRequest signaling.

[0213] In some alternative embodiments, refer to Figure 5 As shown, Figure 5 This is a flowchart illustrating an information transmission method according to an embodiment, which can be applied to unmanned aerial vehicles (UAVs). The method may include the following steps:

[0214] In step 501, a notification message is sent to the base station via a second RRC signaling.

[0215] The notification information is used to inform the base station that the drone has flight path information.

[0216] In the embodiments disclosed herein, the second RRC signaling may reuse existing RRC signaling in the protocol, or it may be a newly defined RRC signaling in the protocol. This disclosure does not limit this.

[0217] In one possible implementation, if the second RRC signaling multiplexing protocol already contains RRC signaling, for a New Radio (NR) network, the second RRC signaling can be any of the following: RRC Reconfiguration Complete signaling; RRC Reestablishment Complete signaling; RRC Resume Complete signaling; RRC Setup Complete signaling.

[0218] In another possible implementation, if the second RRC signaling multiplexing protocol already contains RRC signaling, for Long Term Evolution (LTE) networks, the second RRC signaling can be any of the following: RRC Connection Reconfiguration Complete signaling; RRC Connection Reestablishment Complete signaling; RRC Connection Resume Complete signaling; RRC Connection Setup Complete signaling.

[0219] In step 502, the configuration information sent by the base station after receiving the notification information is received.

[0220] In step 503, if the total number of path points is greater than the maximum number of path points, the target path point is selected on the flight path of the UAV.

[0221] In step 504, the flight path information corresponding to the target waypoint is reported to the base station.

[0222] When the configuration information includes the first method, the implementation of steps 503 to 504 is similar to that of steps 202 to 203. When the configuration information does not include the first method, the implementation of steps 503 to 504 is similar to that of steps 302 to 303. These will not be described again here.

[0223] It should be understood that when the total number of path points is less than or equal to the maximum number of path points, the UAV can report all the flight path information corresponding to the stored total path points to the base station without selecting a target path point from the total path points for reporting. Of course, when the total number of path points is less than or equal to the maximum number of path points, it is also possible to select the target path point to be reported to the base station and report its corresponding flight path information to the base station based on the first method configured by the base station or the second method autonomously selected by the UAV, and this disclosure does not limit this.

[0224] In the above embodiments, the UAV can first send a notification message to the base station via a second RRC signaling, informing the base station that it has flight path information. The base station can then send configuration information to the UAV based on this notification message. This improves the efficiency of the UAV reporting flight path information and ensures high availability.

[0225] It should be understood that in the above embodiments, when the total number of path points stored by the UAV is less than or equal to the maximum number of path points, the UAV can directly report all the flight path information corresponding to each stored path point to the base station.

[0226] The information transmission method provided in this disclosure will now be introduced from the perspective of the base station.

[0227] This disclosure provides an information transmission method, referring to... Figure 6 As shown, Figure 6 This is a flowchart illustrating an information transmission method according to an embodiment, which can be applied to a base station. The method may include the following steps:

[0229] In this embodiment of the disclosure, the configuration information includes at least one of the following: the maximum number of path points allowed for the drone to report; and a first method. The first method is a method in which the drone selects the target path point to be reported to the base station when the total number of path points stored by the drone is greater than the maximum number of path points.

[0233] In step 602, the flight path information corresponding to the target path point is received by the UAV when the total number of path points is greater than the maximum number of path points.

[0234] It should be understood that when the total number of path points is less than or equal to the maximum number of path points, the UAV can report all the flight path information corresponding to the stored total path points to the base station, without needing to select target path points from the total number of path points for reporting. That is, the base station receives the flight path information corresponding to the total path points sent by the UAV. Of course, it is also possible for the base station to receive the flight path information corresponding to the target path points reported by the UAV when the total number of path points is less than or equal to the maximum number of path points, and this disclosure does not limit this.

[0235] In the above embodiments, when the total number of path points stored by the drone exceeds the maximum number of path points allowed for the drone to report, the drone will report the flight path information corresponding to the target path point to the base station.

[0238] In one possible implementation, the first approach is to select the target path points in a first order, where the target path points are path points selected by the UAV on the flight path in the first order.

[0239] In one possible implementation, the first approach is to select the target path points according to the first distribution rule. The first distribution rule can be used to indicate at least one reference path point and a specified number of path points. The reference path points are not limited to at least one of the following: path start point, path end point, and path center point. The target path points are the specified number of path points selected by the UAV on the flight path, among each of the reference path points and the path points adjacent to each of the reference path points.

[0240] In one possible implementation, the first approach is to select the target path point according to the coverage of the base station and / or the neighboring base stations of the base station. The target path point is a path point selected by the UAV on the flight path that is located at the edge of the coverage of the base station and / or a path point located within the coverage of the neighboring base stations.

[0241] Wherein, the target path point is a path point selected by the UAV on the flight path whose first distance value is greater than or equal to a first distance threshold, and / or a path point whose first signal strength is less than or equal to a first signal threshold; wherein, the first distance value is the distance between the path point on the UAV's flight path and the base station, and the first signal strength is the signal strength of the reference signal received by the UAV from the base station.

[0242] And / or, the target waypoint is a waypoint selected by the UAV on the flight path where the second distance value is less than or equal to the second distance threshold, and / or, the waypoint with the second signal strength is less than or equal to the second signal threshold; wherein, the second distance value is the distance between the waypoint on the flight path of the UAV and the neighboring base station, and the second signal strength is the signal strength of the reference signal received by the UAV from the neighboring base station.

[0247] The second method is any one of the following: selecting the target path point according to a second order; selecting the target path point according to a second distribution rule of path points; or selecting the target path point according to the coverage of the base station and / or the neighboring base stations of the base station.

[0248] The method by which the UAV selects the target path point based on the second method refers to the selection method provided in the UAV side implementation, and will not be repeated here.

[0249] In some alternative embodiments, refer to Figure 7 As shown, Figure 7 This is a flowchart illustrating an information transmission method according to an embodiment, which can be applied to a base station. The method may include the following steps:

[0250] In step 701, the configuration information is sent to the UAV via the first Radio Resource Control (RRC) signaling.

[0251] In the embodiments disclosed herein, the first RRC signaling may reuse existing RRC signaling in the protocol, or it may be a newly defined RRC signaling in the protocol. This disclosure does not limit this.

[0252] In one possible implementation, if the first RRC signaling is an existing RRC signaling in the first RRC signaling multiplexing protocol, the first RRC signaling can be UEInformationRequest signaling.

[0253] In step 702, the flight path information corresponding to the target path point is received by the UAV when the total number of path points is greater than the maximum number of path points.

[0254] It should be understood that when the total number of path points is less than or equal to the maximum number of path points, the UAV can report all the flight path information corresponding to the stored total path points to the base station, without needing to select target path points from the total number of path points for reporting. That is, the base station receives the flight path information corresponding to the total path points sent by the UAV. Of course, it is also possible for the base station to receive the flight path information corresponding to the target path points reported by the UAV when the total number of path points is less than or equal to the maximum number of path points, and this disclosure does not limit this.

[0255] In the above embodiments, the base station can send configuration information to the UAV via the first RRC signaling. If the total number of path points stored by the UAV is greater than the maximum number of path points allowed for the UAV to report, the UAV can select target path points to be reported to the base station along its flight path, and the total number of selected target path points is less than or equal to the maximum number of path points. Furthermore, the UAV reports the flight path information corresponding to the target path points to the base station. This improves the efficiency of the UAV reporting flight path information and ensures high availability.

[0265] RRCConnectionReconfigurationComplete signaling;

[0266] RRCConnectionReestablishmentComplete signaling;

[0267] RRCConnectionResumeComplete signaling;

[0268] RRCConnectionSetupComplete signaling.

[0269] In step 802, the configuration information is sent to the drone.

[0270] In this embodiment of the disclosure, after the base station determines that the drone has flight path information based on the notification information, it can send the configuration information to the drone. The configuration information may include at least one of a maximum number of path points and a first method. The first method is a method in which the drone selects the target path point to be reported to the base station when the total number of path points stored by the drone is greater than the maximum number of path points.

[0271] In step 803, the flight path information corresponding to the target path point is received by the UAV when the total number of path points is greater than the maximum number of path points.
