To reduce costs and flight test risks, it is currently necessary to verify networking schemes through simulation. However, existing simulation methods are generally insufficient to meet the high reliability and realism requirements for planning and verification of line-of-sight (LAS) aircraft networking. Summary of the Invention

The technical solution is as follows: In a first aspect, embodiments of this application provide a simulation verification method for aircraft network deployment mission planning, comprising: determining a preset flight path for the aircraft; responding to receiving network planning parameters input via an interface display module, invoking a preset network site deployment algorithm to generate line-of-sight network site deployment information; wherein the network planning parameters include the number of sites, transmit power, antenna height, signal frequency, and obstacle parameters; the line-of-sight network site deployment information includes the latitude and longitude information of the target site, the elevation information of the target site, and the coverage area of ​​the target site; and performing an adaptive pre-handover decision based on a preset cross-regional network handover algorithm, combined with the preset flight path and the coverage area of ​​the target site, to generate a handover triggering mechanism. The system implements a cross-regional handover strategy for line-of-sight (LAS) networking, including candidate target site sequences and handover execution conditions. Within a 3D digital map environment imported via the interface display module, based on the LAS site layout information and the LAS cross-regional handover strategy, the system synchronously and dynamically simulates the aircraft's attitude change along a preset flight path, as well as the establishment, maintenance, interruption, and handover processes of the LAS communication link between the aircraft and the target site, obtaining simulation data.

[0008] In one implementation, the aircraft networking mission planning simulation verification method generates a data rate-time curve and a handover event sequence diagram. The data rate-time curve is a curve with time on the horizontal axis and data rate on the vertical axis. The handover event sequence diagram is used to identify the occurrence time and handover status of each link handover event in a time sequence. The handover status is the state of the communication link during the cross-regional link handover process of the aircraft, including the handover start state, handover in progress state, handover successful state, and handover failed state. The data rate-time curve and the handover event sequence diagram are displayed on the interface display module.

Furthermore, based on a preset cross-regional network handover algorithm and combined with a preset flight path and target site coverage area, adaptive pre-handover decisions are made to generate a LAS network cross-regional handover strategy, including handover trigger timing, candidate target site sequence, and handover execution conditions. Dynamic simulation is then performed in a 3D digital map environment in conjunction with LAS constraints, which more realistically recreates the attitude changes and communication link connection / disconnection processes of the aircraft flying along the preset path, significantly improving the realism and reliability of network planning verification. In addition, by introducing site deployment information and cross-regional handover strategies for joint simulation, and completing closed-loop verification based on quantitative indicators such as connectivity rate and handover success rate, the problems of insufficient realism, unreliable verification results, and difficulty in comprehensively evaluating the performance of network schemes in traditional simulation methods are effectively solved, providing a more accurate and reliable verification method for aircraft LAS network planning.

[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0018] The first aspect of this application provides a simulation verification method for aircraft networking mission planning. Exemplarily, the aircraft can be an unmanned aerial vehicle (UAV). Exemplarily, the aircraft networking mission planning simulation verification method can be applied to an aircraft networking mission planning simulation verification system. The aircraft networking mission planning simulation verification system may include an interface display module. The interface display module may have options for importing a map, deploying a site, adding an aircraft, selecting an algorithm, starting flight, playing events, and real-time verification. The interface display module may include a map management unit, a site deployment unit, an aircraft addition unit, an algorithm selection unit, a flight unit, an event broadcasting unit, and a real-time verification unit.

[0019] Users can access the map management unit by clicking the "Import Map" option. The map management unit displays a list of successfully imported maps, and users can switch between maps by clicking on an item in the list. Alternatively, users can import offline map data in pyramid tile format. This map data is organized and packaged into a compressed file according to a directory structure of zoom level (z), horizontal index (x), and vertical index (y). By importing a compressed file that conforms to this directory structure, the offline map data can be loaded and parsed. In case of map import errors, the corresponding map file can be deleted by clicking the "Delete" option in the map list.

[0020] Users can access the site management module by clicking the "Deploy Site" option. The site management module displays a list of sites, which can be deployed by clicking on an item in the list. New sites can also be added and stored in the database. If the current site information is no longer needed, the current site data can be deleted by clicking the "Delete" option in the site list.

[0021] Users can access the aircraft addition section by clicking the "Add Aircraft" option. This section includes an aircraft parameter settings interface where users can input various aircraft parameters (such as flight speed, altitude, and radius). After inputting the parameters, users can click "Confirm Add" and then click on the desired map location to add the aircraft. Clicking on the aircraft will bring up a waypoint dialog box. Clicking "Add Waypoint" and then clicking on the corresponding point on the map will add the waypoint. Finally, clicking "Save Waypoints" completes the waypoint planning and generates the aircraft's preset flight path.

[0022] Users can access the algorithm selection unit by clicking the algorithm selection option. This unit displays various algorithms, including, for example, the fixed-weight method and the entropy-weight method. Depending on the algorithm selected by the user, the aircraft networking mission planning simulation verification system will employ different algorithms to verify the communication links during the simulated flight of the aircraft.

[0023] Users can enter the flight unit by clicking the "Start Flight" option, at which point the aircraft can simulate flight according to a preset flight path. When the aircraft enters the site's coverage area, the aircraft networking mission planning simulation verification system verifies the connectivity status of the current communication link based on the algorithm selected by the user and displays it visually on the interface. For example, if the current communication link is connected, the corresponding link is marked with a white area; if the current communication link is disconnected, the original display color remains unchanged.

[0024] Users can enter the event playback unit by clicking the event playback option. The event playback unit displays various events during the flight of the aircraft, such as system pause, aircraft status update, signal strength change, verification data update, etc.

[0025] Users can access the real-time verification unit by clicking the real-time verification option. This unit displays verification data from both the aircraft and the station during flight. The verification data can be downloaded by clicking the download option in the real-time verification unit.

[0026] Figure 1 This diagram illustrates a flowchart of the simulation verification method for aircraft networking mission planning provided in an embodiment of this application. Figure 1 As shown, the simulation verification method for the aircraft networking mission planning can include: Step S101: Determine the aircraft's preset flight path.

[0027] For example, the preset flight path can be the flight path obtained by the user through waypoint planning via the interface display module. Specifically, the user can input various parameters of the aircraft and add waypoints through the interface display module to achieve waypoint planning and obtain the preset flight path.

[0028] Step S102: In response to receiving network planning parameters input via the interface display module, a preset network site deployment algorithm is invoked to generate line-of-sight (LAS) network site deployment information. The network planning parameters include the number of sites, transmit power, antenna height, signal frequency, and obstacle parameters. The LAS network site deployment information includes the target site's latitude and longitude, elevation, and coverage area. Thus, by receiving user-input network planning parameters and automatically invoking the network site deployment algorithm for optimization calculations, the system can quickly generate target site locations and coverage information that meet LAS communication constraints. This eliminates the need for manual point-by-point deployment and repeated verification, significantly improving the efficiency and scientific rigor of aircraft network planning. Simultaneously, the generated target site latitude and longitude, elevation, and coverage information can be directly used for simulation verification and actual engineering deployment, effectively reducing network planning complexity and improving link connectivity reliability and solution feasibility.

[0029] Transmission power refers to the intensity of the wireless signal transmission. Higher transmission power results in farther signal coverage and stronger resistance to signal attenuation. Antenna height refers to the installation height of the communication antenna above the ground, directly affecting the establishment of line-of-sight communication. A higher antenna provides a farther line of sight and is less likely to be blocked by obstacles such as buildings or mountains. Signal frequency refers to the electromagnetic wave frequency used in wireless communication, such as 900MHz, 1.4GHz, 2.4GHz, or 5.8GHz. The signal frequency determines the signal attenuation rate, and the pre-defined site deployment algorithm uses this to calculate whether the link can be established and whether the signal strength meets the requirements. Obstacle parameters are fixed values; that is, the location, height, and range of obstacles are preset and do not change dynamically.

[0030] For example, users can input network planning parameters through the interface display module. After receiving the network planning parameters input by the user, the aircraft network mission planning simulation verification system calls a preset network site deployment algorithm. This algorithm can automatically generate line-of-sight (LAS) network site deployment information according to the requirements of LAS. The LAS requirement refers to an unobstructed straight-line propagation path between the transmitting and receiving ends of the communication, ensuring that the wireless signal can be transmitted in a straight line and avoiding signal obstruction, attenuation, or communication interruption caused by obstacles such as terrain and buildings. For example, if the user inputs three sites through the interface display module, the number of target sites will be three. The preset network site deployment algorithm can generate the latitude and longitude information, elevation information, and coverage area of ​​the three target sites, achieving optimal overall site coverage performance.

[0031] Step S103: Based on a preset cross-regional network handover algorithm, and combined with a preset flight path and target site coverage area, adaptive pre-handover decision is made to generate a line-of-sight (LAS) network cross-regional handover strategy, including handover trigger timing, candidate target site sequence, and handover execution conditions. By combining the preset flight path and target site coverage area, and using a cross-regional network handover algorithm for adaptive pre-handover decision, reasonable handover trigger timing, candidate target site sequence, and handover execution conditions can be planned and generated in advance. This enables smooth, stable, and low-latency cross-regional handover of the aircraft in different site coverage areas; effectively avoids communication interruptions, link jitter, and data packet loss caused by handover lag; ensures the continuity and reliability of the LAS communication link during long-endurance and wide-area flight; and improves the overall robustness of the network system.

[0032] For example, the preset cross-regional network handover algorithm can be the algorithm selected by the user by clicking the algorithm selection option. The user can also input handover parameters (such as signal-to-noise ratio, bit error rate, transmission rate, signal strength, connectivity, weight, etc.) through the interface display module. In this case, the handover parameters and the line-of-sight network site deployment information are both inputs to the preset cross-regional network handover algorithm.

[0033] The handover triggering timing refers to the starting point for cross-area handover in line-of-sight (LAS) networking. Specifically, it specifies when and under what conditions the aircraft (e.g., flying to a certain latitude and longitude, entering a certain coverage area) begins preparing to hand over to the target site, avoiding handover delays or premature handovers. The candidate target site sequence refers to multiple target sites arranged in priority order. The sorting criteria can include signal-to-noise ratio (SNR), bit error rate (BER), transmission rate, signal strength, connectivity, and weight. For example, if there are three target sites, A, B, and C, and the first priority is site A (best signal, highest connectivity), the second priority is site B (second best signal), and the third priority is site C (emergency backup), then the candidate target site sequence is site A → site B → site C, ensuring consistent access to the optimal communication site. The handover execution conditions refer to the conditions that must be met for the handover to be truly executed. These conditions include: the signal strength of the target site being higher than a certain threshold; the signal-to-noise ratio meeting the requirements for line-of-sight communication; the bit error rate being lower than a set value; the existence of line-of-sight with the target site; the aircraft having entered the stable coverage area of ​​the target site; and the current link quality continuously deteriorating to the point where handover is necessary. This can improve handover reliability, effectively avoid link interruptions, data packet loss, and frequent handovers, and ensure the continuity and stability of communication links in large-scale line-of-sight networking scenarios.

[0034] Step S104: In the 3D digital map environment imported via the interface display module, based on the line-of-sight (LAS) network site layout information and the LAS cross-regional switching strategy, the attitude change process of the aircraft along the preset flight path, the establishment, maintenance, interruption and switching process of the LAS communication link between the aircraft and the target site are synchronously and dynamically simulated to obtain simulation data; among which, the simulation data includes connectivity rate, data rate, number of site switching, average switching speed and switching success rate.

[0035] For example, the 3D digital map can be a map imported by the user by clicking the import map option. The resolution of this 3D digital map can be within 50 meters, meaning the smallest geographic unit on the map corresponds to an actual ground distance of no more than 50 meters, to ensure the accuracy of site deployment, line-of-sight link determination, and flight path planning.

[0036] The connectivity rate is the ratio of link connectivity time to total flight time during the entire flight. The data rate is the amount of data transmitted per unit time. The number of site handovers is the total number of times the aircraft needs to switch sites throughout the entire flight. The average handover speed is the average time from initiation to completion of each handover. The handover success rate is the percentage of successful handovers to the target site after a handover is triggered.

[0037] In step S104, two core processes can be simulated simultaneously and dynamically. The first core process is the simulation of the aircraft's attitude change along a preset flight path, presenting the changes in the aircraft's position, heading, and attitude (such as climb, turn, and level flight) in real time, consistent with the actual flight state. The second core process is the establishment, maintenance, interruption, and switching of the line-of-sight (LAS) communication link between the aircraft and the target station. Specifically, when the aircraft enters the coverage area of ​​the target station and meets the LAS requirements, the LAS communication link between the aircraft and the target station is established. During flight, if the link is stable and the signal is normal, the LAS communication link between the aircraft and the target station is maintained. When the aircraft flies out of the target station's coverage area or is obstructed by obstacles, the LAS communication link between the aircraft and the target station is interrupted. When the switching trigger timing is reached and the switching execution conditions are met, the system switches to the next target station according to the candidate target station sequence, completing the link switching.

[0038] By importing a 3D digital map environment and combining line-of-sight (LOS) network site deployment information with cross-regional handover strategies, the simulation dynamically simulates the entire process of aircraft flight attitude changes and the establishment, maintenance, interruption, and handover of LOS communication links. This enables simulation verification of low-altitude LOS networking schemes without the need for actual aircraft and site deployment. By generating quantitative simulation data such as connectivity rate, data rate, number of site handovers, average handover speed, and handover success rate, the rationality of site deployment, the scientific nature of handover strategies, and the stability of link communication can be intuitively and accurately evaluated. This effectively reduces testing costs and risks before actual deployment and avoids problems such as actual flight disconnection and handover failure due to unreasonable schemes. At the same time, the simulation process is visualized and the data is quantifiable, facilitating rapid optimization of site deployment locations and adjustment of handover strategy parameters, improving the reliability and feasibility of LOS networking schemes, and shortening the scheme iteration cycle.

[0039] Step S105: Verify the generated line-of-sight network site layout information and line-of-sight network cross-regional handover strategy based on simulation data, and display the generated verification results on the interface display module.

[0040] In step S105, based on simulation data, the following can be verified: First, the latitude and longitude information, elevation information, and coverage area of ​​the target station can be verified to ensure their rationality. For example, are there blind spots in the target station coverage area? Can the line-of-sight communication requirements be met? Can the deployment location guarantee link connectivity? Second, the following can be verified to ensure the scientific validity of the handover triggering timing, candidate target station sequence, and handover execution conditions. For example, is the handover timely? Does the handover success rate meet the standards? Can the average handover speed avoid disconnection? Is the number of handovers reasonable? Furthermore, the verification results can be displayed intuitively on the interface, eliminating the need for users to manually process massive amounts of simulation data. This reduces the complexity of scheme evaluation, allowing users to quickly determine the feasibility of the networking scheme and promptly optimize network planning parameters and handover strategies, further improving the stability and feasibility of low-altitude line-of-sight networking. Simultaneously, closed-loop verification reduces debugging costs and risks after actual deployment, shortens the scheme iteration cycle, and improves the overall efficiency of network planning.

[0041] The simulation and verification method for aircraft network planning according to embodiments of this application receives network planning parameters input via an interface display module and calls a preset network site deployment algorithm to generate line-of-sight (LAS) network site deployment information. It also performs adaptive pre-handover decision based on a preset cross-regional network handover algorithm and a preset flight path and target site coverage, generating a LAS cross-regional network handover strategy including handover trigger timing, candidate target site sequence, and handover execution conditions. Furthermore, dynamic simulation is performed in a 3D digital map environment combined with LAS constraints, which more realistically recreates the attitude changes and communication link connection / disconnection processes of the aircraft flying along the preset path, significantly improving the realism and reliability of network planning verification. In addition, by introducing joint simulation of site deployment information and cross-regional handover strategy, and completing closed-loop verification based on quantitative indicators such as connectivity rate and handover success rate, it effectively solves the problems of insufficient realism, unreliable verification results, and difficulty in comprehensively evaluating the performance of network schemes in traditional simulation methods, providing a more accurate and reliable verification means for aircraft LAS network planning.

[0042] In one implementation, the simulation data may further include switching status, timestamps, and the aircraft's position information at the time of each link switching event; wherein, the switching status refers to the state of the communication link during the cross-regional link switching process of the aircraft, and the switching status includes switching start status, switching in progress status, switching successful status, and switching failed status. The aircraft networking task planning simulation verification method may further include: associating the switching status, timestamps, and the aircraft's position information at the time of switching with the target station's position data and the aircraft's real-time flight position data to obtain an association result; based on the association result, mapping the switching status to corresponding visual display parameters to dynamically and visually display the switching status on the interface display module; the visual display parameters include the color of the connection between the aircraft and the target station, the flashing frequency of the connection, and the transparency of the connection.

[0043] It should be noted that the target station location data includes the target station's latitude and longitude information and its elevation information.

[0044] For example, the communication and handover process can be represented by a colored flashing line between the aircraft and the target station. For instance, when the handover is in progress, the line between the aircraft and the target station can be yellow, flashing at a frequency of 2 times per second, and the line's transparency can decrease over time. When the handover is successful, the line between the aircraft and the target station can be green, flashing slowly (e.g., at a frequency less than 1 time per second) twice before remaining constantly lit. Thus, different handover states can be represented by the color of the line between the aircraft and the target station; the flashing frequency can indicate whether a handover is in progress; and the transparency of the line can indicate the link quality or status strength, thereby dynamically, intuitively, and in real-time displaying the entire handover process.

[0045] In this embodiment, by introducing switching status, timestamps, and aircraft location information into the simulation data, and associating this information with the target site location and the real-time aircraft location, the entire process of cross-regional link switching can be completely recorded, enabling refined recording and traceable management of switching events. By mapping different switching statuses to visual display parameters such as the color, flashing frequency, and transparency of the connection between the aircraft and the target site, the switching process can be dynamically visualized on a 3D digital map interface. This allows users to intuitively and quickly identify the switching status, switching results, and the location where the switching occurs, significantly improving the readability and interactivity of the simulation process. Furthermore, compared to existing technologies, this embodiment can more meticulously and realistically reflect the details of link switching, facilitating rapid identification of the causes of switching failures, optimization of switching strategy parameters, and further improving the comprehensiveness, accuracy, and ease of use of network planning simulation verification.

[0046] In one embodiment, after receiving network planning parameters input via the interface display module in step S102, and calling a preset network site deployment algorithm to generate line-of-sight network site deployment information, the aircraft network mission planning simulation verification method may further include: traversing multiple target sites, adding site markers corresponding to the target sites and the coverage area of ​​the target sites on a three-dimensional digital map; and in response to receiving that the mouse pointer is located at a site marker, displaying the latitude and longitude information, elevation information, and coverage area of ​​the target site corresponding to the site marker on the interface display module.

[0047] For example, users can input the target site type (e.g., base station, monitoring station, and relay station) through the interface display module. Different types of target sites can have different site markers added, and different site markers can be presented through different icons. In addition, the target site coverage area can be rendered using circles or polygons. The rendered target site coverage area is displayed semi-transparently, rather than as a solid color, to avoid obstructing the 3D terrain, aircraft, site markers, and flight paths.

[0048] In this embodiment, by adding markers and drawing coverage areas for each target site on a 3D digital map, the distribution and coverage of network sites can be visualized, allowing users to intuitively and comprehensively grasp the network planning layout effect. By automatically displaying the latitude and longitude information, elevation information, and coverage area of ​​the corresponding target site when the mouse pointer hovers over the site marker, interactive and rapid querying of site information is achieved, eliminating the need for manual searching or comparison of data, thus improving the usability and ease of operation of the planning interface. Simultaneously, the combination of visualized layout and interactive information viewing helps users promptly identify problems such as unreasonable site deployment, overlapping coverage, or coverage blind spots, facilitating rapid adjustment of planning parameters and optimization of the network scheme, further improving the efficiency and intuitiveness of aircraft line-of-sight network planning.

[0049] In one implementation, traversing multiple target stations and adding corresponding station markers and coverage areas to the 3D digital map can include: traversing multiple target stations and determining whether each target station is within the coverage area of ​​the 3D digital map based on its latitude and longitude information; if a target station is within the coverage area of ​​the 3D digital map, adding corresponding station markers and coverage areas to the 3D digital map. By determining whether a target station is within the coverage area of ​​the 3D digital map before traversing it, and only adding markers and rendering coverage areas for stations within the map's visible area, redundant display of invalid stations outside the map can be avoided, reducing interface rendering overhead and improving the loading and display efficiency of the 3D map interface. Simultaneously, it can prevent display errors and interface clutter caused by station markers and coverage areas exceeding the map's visible area, ensuring a clean and clear network planning interface and improving simulation visualization and user experience.

[0050] Figure 2 This diagram illustrates an application example of the simulation verification method for aircraft networking mission planning provided in this application. In one embodiment, referring to... Figure 2 Simulation data may also include bit error rate and signal-to-noise ratio. The simulation verification method for aircraft networking mission planning may further include: dividing the simulation data into site deployment performance index data and link handover performance index data; wherein, the site deployment performance index data includes connectivity and data rate; the link handover performance index data includes the number of site handovers, average handover speed, handover success rate, bit error rate, and signal-to-noise ratio; and displaying the site deployment performance index data and link handover performance index data in different areas of the interface display module.

[0051] In this embodiment, by incorporating bit error rate and signal-to-noise ratio into the simulation data, the transmission quality of the communication link can be reflected more comprehensively and accurately. By dividing the simulation data into site deployment performance indicators and link switching performance indicators and displaying them in different areas of the interface, the performance evaluation data is presented in a structured and organized manner. This allows users to independently evaluate the rationality of site deployment and the reliability of link switching, avoiding information confusion caused by the mixed display of multiple indicators, and improving the readability and analysis efficiency of the simulation results. At the same time, it helps users quickly locate network performance shortcomings and optimize site deployment parameters or switching strategy parameters in a targeted manner, thereby improving the pertinence and efficiency of simulation verification and solution iteration.

[0052] In one embodiment, the simulation verification method for aircraft networking mission planning may further include: generating a data rate-time curve and a handover event sequence diagram; wherein, the data rate-time curve is a curve with time as the horizontal axis and data rate as the vertical axis; the handover event sequence diagram is used to identify the occurrence time and handover status of each link handover event in a time sequence; the handover status is: the state of the communication link during the cross-regional link handover of the aircraft, and the handover status includes the handover start state, the handover in progress state, the handover successful state, and the handover failed state; and displaying the data rate-time curve and the handover event sequence diagram on the interface display module.

[0053] In this embodiment, by generating a data rate-time curve and a handover event sequence diagram, the communication performance and handover events during the simulation are visualized graphically and sequentially. The data rate-time curve can intuitively reflect the fluctuation pattern of the communication transmission rate throughout the flight, facilitating the rapid identification of rate anomalies and link bottlenecks. The handover event sequence diagram can accurately present the occurrence time and handover status of each handover event in a time sequence, enabling the handover process to be traceable and located. Displaying both types of charts simultaneously on the interface facilitates the correlation analysis between transmission rate changes and handover events, helping users accurately determine whether link fluctuations are caused by handover, quickly locate the root cause of handover failures, rate jitter, and other problems, significantly improving the professionalism, intuitiveness, and efficiency of simulation data analysis, and providing clear and intuitive data support for network scheme optimization.

[0054] The second aspect of this application provides a simulation and verification system for aircraft networking mission planning. Figure 3 This diagram illustrates the architecture of the aircraft networking mission planning simulation verification system provided in an embodiment of this application. Figure 3As shown, the aircraft networking mission planning simulation verification system 300 includes an interface display module 310, a scheme planning module 320, a simulation module 330, and a performance verification module 340. The interface display module 310 is used to input networking planning parameters. The scheme planning module 320 is communicatively connected to the interface display module 310 and is used to determine the aircraft's preset flight path. In response to receiving the networking planning parameters input via the interface display module 310, it calls a preset network site deployment algorithm to generate line-of-sight (LAS) network site deployment information. The networking planning parameters include the number of sites, transmit power, antenna height, signal frequency, and obstacle parameters. The LAS network site deployment information includes the target site's latitude and longitude information, target site's elevation information, and target site coverage area. Based on a preset cross-regional networking handover algorithm, and combined with the preset flight path and target site coverage area, an adaptive pre-handover decision is made to generate a LAS network cross-regional handover strategy, including the handover trigger timing, candidate target site sequence, and handover execution conditions. The simulation module 330 is communicatively connected to the scheme planning module 320. It is used to synchronously and dynamically simulate the attitude changes of the aircraft along a preset flight path, and the establishment, maintenance, interruption, and switching processes of the line-of-sight communication link between the aircraft and the target station, based on the line-of-sight network site layout information and the cross-regional switching strategy, within a 3D digital map environment imported via the interface display module 310. The simulation data includes connectivity, data rate, number of site switching times, average switching speed, and switching success rate. The performance verification module 340 is communicatively connected to both the simulation module 330 and the interface display module 310. It is used to verify the generated line-of-sight network site layout information and the cross-regional switching strategy based on the simulation data, and displays the verification results on the interface display module 310.

[0055] The aircraft networking mission planning simulation verification system 300 according to an embodiment of this application generates line-of-sight (LAS) network site layout information by having the scheme planning module 320 receive networking planning parameters input via the interface display module 310 and call a preset network site deployment algorithm. It also generates a LAS network cross-regional handover strategy based on a preset cross-regional network handover algorithm combined with a preset flight path and target site coverage, including handover triggering timing, candidate target site sequence, and handover execution conditions. Furthermore, the simulation module 330 performs dynamic simulation in a 3D digital map environment combined with LAS constraints, more realistically reproducing the attitude changes and communication link connection / disconnection processes of the aircraft flying along the preset path, significantly improving the realism and reliability of the networking planning verification. In addition, by introducing joint simulation of site deployment information and cross-regional handover strategies, and completing closed-loop verification based on quantitative indicators such as connectivity rate and handover success rate, it effectively solves the problems of insufficient realism, unreliable verification results, and difficulty in comprehensively evaluating the performance of networking schemes in traditional simulation methods, providing a more accurate and reliable verification method for aircraft LAS network planning.

[0056] In one embodiment, the aircraft networking mission planning simulation verification system 300 may further include a data receiving module, a data processing module, and a visualization conversion module. The data receiving module receives simulation data. The data processing module parses the simulation data, extracts the switching status, timestamps, and aircraft position information at the time of each link switching event, and associates the switching status, timestamps, and aircraft position information at the time of switching with target station position data and real-time aircraft flight position data to obtain an association result. The switching status refers to the state of the communication link during the aircraft's cross-regional link switching process, including switching start, switching in progress, switching successful, and switching failed states. The visualization conversion module is communicatively connected to the data processing module and the interface display module 310. Based on the association result, it maps the switching status to corresponding visual display parameters, dynamically and visually displaying the switching status on the interface display module 310. The visual display parameters include the color of the connection between the aircraft and the target station, the flashing frequency, and the connection transparency.

[0057] It should be noted that the target station location data includes the target station's latitude and longitude information and its elevation information.

[0058] For example, the communication and handover process can be represented by a colored flashing line between the aircraft and the target station. For instance, when the handover is in progress, the line between the aircraft and the target station can be yellow, flashing at a frequency of 2 times per second, and the line's transparency can decrease over time. When the handover is successful, the line between the aircraft and the target station can be green, flashing slowly (e.g., at a frequency less than 1 time per second) twice before remaining constantly lit. Thus, different handover states can be represented by the color of the line between the aircraft and the target station; the flashing frequency can indicate whether a handover is in progress; and the transparency of the line can indicate the link quality or status strength, thereby dynamically, intuitively, and in real-time displaying the entire handover process.

[0059] In this embodiment, by introducing switching status, timestamps, and aircraft location information into the simulation data, and associating this information with the target site location and the real-time aircraft location, the entire process of cross-regional link switching can be completely recorded, enabling refined recording and traceable management of switching events. By mapping different switching statuses to visual display parameters such as the color, flashing frequency, and transparency of the connection between the aircraft and the target site, the switching process can be dynamically visualized on a 3D digital map interface. This allows users to intuitively and quickly identify the switching status, switching results, and the location where the switching occurs, significantly improving the readability and interactivity of the simulation process. Furthermore, compared to existing technologies, this embodiment can more meticulously and realistically reflect the details of link switching, facilitating rapid identification of the causes of switching failures, optimization of switching strategy parameters, and further improving the comprehensiveness, accuracy, and ease of use of network planning simulation verification.

[0060] In one embodiment, the aircraft networking mission planning simulation verification system 300 may further include a marker adding module, which is used to traverse multiple target stations, add station markers corresponding to the target stations and the coverage area of ​​the target stations on a three-dimensional digital map; in response to receiving that the mouse pointer is located at a station marker, the latitude and longitude information, elevation information and coverage area of ​​the target station corresponding to the station marker are displayed on the interface display module 310.

[0061] In one implementation, the marker adding module can also be used to traverse multiple target stations and determine whether each target station is within the coverage area of ​​the 3D digital map based on the latitude and longitude information of each target station; if the target station is within the coverage area of ​​the 3D digital map, add a station marker corresponding to the target station and the coverage area of ​​the target station on the 3D digital map.

[0062] In one implementation, the simulation data may further include bit error rate and signal-to-noise ratio; the aircraft networking mission planning simulation verification system 300 may further include: a data partitioning module, used to partition the simulation data into site deployment performance index data and link switching performance index data; wherein, the site deployment performance index data includes connectivity rate and data rate; the link switching performance index data includes site switching count, average switching speed, switching success rate, bit error rate, and signal-to-noise ratio; the site deployment performance index data and link switching performance index data are displayed in different areas of the interface display module 310.

[0063] In one embodiment, the aircraft networking mission planning simulation verification system 300 may further include: a chart generation module for generating a data rate-time curve and a handover event sequence diagram; wherein, the data rate-time curve is a curve with time as the horizontal axis and data rate as the vertical axis; the handover event sequence diagram is used to identify the occurrence time and handover status of each link handover event in a time sequence; the handover status is: the state of the communication link during the cross-regional link handover of the aircraft, and the handover status includes the handover start state, the handover in progress state, the handover successful state, and the handover failed state; the data rate-time curve and the handover event sequence diagram are displayed on the interface display module 310.
