Description

Technical Field

[0001] This application relates to the field of satellite communication technology, and in particular to a direct satellite communication method, apparatus, electronic device, and storage medium. Background Technology

[0002] With the continuous development of low-Earth orbit (LEO) satellite communication technology, direct communication between LEO satellites and terminals has been realized. However, due to the limited communication range covered by LEO satellites, in order to provide continuous and high-quality communication services to the target terminal, it is necessary to constantly switch LEO satellites. This can easily lead to communication interruptions for the target terminal during the LEO satellite switching process. To avoid this, when the target terminal is located at a specific position within the communication range of the initial satellite, the target satellite is selected from multiple candidate satellites. When the target terminal is located at the edge of the communication range, the switching between the initial satellite and the target satellite begins.

[0003] However, existing satellite handover methods are affected by the satellite itself or the environment, and there are cases where the initial satellite and the target satellite fail to communicate, which leads to the interruption of communication of the target terminal and reduces the stability of the target terminal's communication.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] This application provides a direct satellite communication method, which can be executed by an electronic device. The electronic device can be a server, which can be an independent physical server, a server cluster composed of multiple physical servers, or a distributed device, or a cloud server that provides cloud computing services. The server can be installed on a ground terminal, a low-Earth orbit satellite, or a high-Earth orbit satellite.

[0040] Reference Figure 1 A direct satellite communication method includes steps S101, S102, S103, and S104, wherein...

[0041] S101, determine the first relative positional relationship, wherein the first relative positional relationship is the positional relationship between the target position of the target terminal and the first communication range of the initial satellite.

[0042] In some embodiments, the target terminal is a communication device located on the ground or flying at low altitude, the initial satellite is a low-orbit satellite currently providing direct communication services to the target terminal, and the first communication range is the range within which the initial satellite can provide high-quality and stable communication services.

[0043] The electronic device first acquires the initial communication range corresponding to the initial satellite, where the initial communication range is the maximum communication service range that the initial satellite can provide. It then determines the test terminal for communication quality testing from the initial communication range and, based on the acquired test communication data of the test terminal, determines the first communication range from the initial communication range. Subsequently, the electronic device inputs the acquired target position of the target terminal and the first communication range into the three-dimensional model software to construct a spatial model between the target terminal and the first communication range, and determines the first relative positional relationship between the target terminal and the first communication range based on the spatial model.

[0044] S102, based on the first relative position relationship, generates storage instructions and determines the target satellite.

[0045] In some embodiments, the storage instruction is a control instruction for storing target communication information sent by the target terminal, and the target satellite is a satellite adjacent to the initial satellite that will soon provide direct communication services to the target terminal.

[0046] The target terminal establishes initial connections with multiple candidate satellites simultaneously. While the target terminal is in direct communication with the initial satellite, multiple candidate satellites establish communication connections with the target terminal but do not provide communication services to the target terminal. When the first relative position relationship is specific, it indicates that the target terminal is about to leave the first communication range of the initial satellite. In order to avoid communication interruption of the target terminal during the subsequent communication switch to the initial satellite, it is advisable to store the target communication information sent by the target terminal while the target terminal is about to leave the first communication range, and at the same time determine the target satellite that will provide communication services to the target terminal from among the multiple candidate satellites.

[0047] S103, when the target location is located at a preset location point within the first communication range, and the communication information storage completion information is obtained based on the storage instruction, a communication switching instruction and an information sending instruction are generated.

[0048] In some embodiments, when the target location of the target terminal is located at a preset location point within the first communication range, it indicates that the target terminal is about to leave the first communication range of the initial satellite and the initial satellite can no longer provide stable and high-quality communication services to the target terminal. At this time, satellite communication switching can be performed. During the switching process, the stored target communication information is sent. That is, when the electronic device is located at the preset location point within the first communication range and obtains the communication information storage completion information based on the storage instruction, the electronic device generates a communication switching instruction and an information sending instruction, and completes the satellite switching between the initial satellite and the target satellite based on the communication switching instruction and the information sending instruction, and completes the transmission of the target communication information of the target terminal stored in the storage device.

[0049] S104, based on the communication switching command, controls the initial satellite and the target satellite to complete the communication switching, and based on the information transmission command, sends the target communication information stored based on the storage command to the target satellite.

[0050] In some embodiments, the electronic device sends communication switching instructions to the initial satellite and the target satellite, thereby controlling the initial satellite and the target satellite to complete the communication switching, and sends information transmission instructions to a storage device storing the target terminal's target communication information. The storage device can be installed at a ground communication center, on a low-Earth orbit satellite, or on a high-Earth orbit satellite covering the target location of the target terminal. By storing the target terminal's target communication information and selecting the target satellite from multiple candidate satellites with pre-established initial connections, and sending the stored target communication information to the target satellite during the initial satellite's communication switching process, the probability of communication interruption of the target terminal during the initial satellite communication switching is reduced, thereby improving the stability of the target terminal's communication.

[0051] In step S101, determining the first relative position relationship includes: acquiring the target position of the initial satellite and the initial communication range of the initial satellite; setting multiple test position points within the initial communication range and determining the test ranges corresponding to the multiple test position points respectively; acquiring the test communication data corresponding to the test terminals within the multiple test ranges and determining the communication data quality corresponding to the multiple test communication data respectively; if the data quality difference between any two adjacent communication data qualities exceeds a preset data quality difference range, the test position point corresponding to the best data quality among any two adjacent communication data qualities is taken as the edge point of the first communication range corresponding to the initial satellite, and the first communication range is constructed based on the edge point.

[0052] In some embodiments, the initial communication range is the maximum communication range that the initial satellite can provide communication services to the target terminal; multiple test location points are simultaneously located on the same radius line within the initial communication range.

[0053] The electronic device randomly determines a radius line within the initial communication range. Based on the retrieved location points and range determination rules, it uniformly determines multiple test location points from this radius line and the test range corresponding to each test location point. The multiple test ranges are of equal size and shape, and the edge points corresponding to two adjacent test ranges coincide, with these edge points located on the same radius line. Subsequently, the electronic device randomly acquires test communication data corresponding to the test terminal within each test range. This test communication data is the communication data sent by the test terminal initially acquired by the satellite. Simultaneously, the electronic device acquires the initial test communication data corresponding to this test communication data from the test terminal. Based on the test communication data and the initial communication data, it determines the communication data quality corresponding to each communication data.

[0054] The electronic device compares multiple communication data based on the principle of comparing the quality of two adjacent communication data to determine multiple data quality differences. Then, the electronic device compares the multiple data quality differences with a preset data quality difference range. If any data quality difference exceeds the preset data quality difference range, it indicates that there is a large gap between the two communication data quality corresponding to that data quality difference. This means that the test communication data corresponding to the communication data quality closer to the edge of the initial communication range is affected by factors such as geographical location and is distorted. Therefore, the electronic device can take the test location point corresponding to the best communication data quality among the two communication data quality differences as the edge point of the first communication range. Then, the line connecting the edge point and the center point of the initial communication range is taken as the radius line of the first communication range to construct the first communication range.

[0055] Step S102, based on the first relative position relationship, generates a storage instruction and determines the target satellite, including: determining the first relative running speed between the target terminal and the initial satellite; based on the first relative running speed and the first relative position relationship, determining the communication duration for the target satellite to leave the first communication range; obtaining the transmission rate and data volume of a single batch of communication data corresponding to the target terminal; based on the transmission rate and data volume, determining the transmission duration corresponding to the single batch of communication data, and generating a storage instruction based on the transmission duration and communication duration.

[0056] In some embodiments, the electronic device acquires the terminal's running direction and speed of the target satellite, as well as the satellite's running direction and speed corresponding to the initial satellite, and calculates the relative running speed between the target terminal and the initial satellite based on the terminal's running direction, terminal's running speed, satellite's running direction, and satellite's running speed; subsequently, the electronic device determines the distance the target terminal travels away from the first communication range based on the first relative position relationship, and calculates the communication duration of the target terminal traveling away from the first communication range based on the distance and the first relative running speed.

[0057] In addition, the electronic device acquires the transmission rate of a single batch of communication data from the target terminal and the corresponding amount of communication data. Then, it calculates the transmission time required for a single batch of communication data to be transmitted from the start to the end, compares the transmission time with the communication time, and generates a storage instruction if the two meet specific requirements.

[0058] In some embodiments, generating a storage instruction based on transmission duration and communication duration includes: setting a communication duration range based on the communication duration, wherein the communication duration is used as the minimum duration point of the communication duration range, twice the communication duration is used as the maximum duration point of the communication duration range, and the communication duration range includes the minimum duration point but does not include the maximum duration point; generating a storage instruction when the transmission duration is within the communication duration range.

[0059] In some embodiments, the electronic device sets a communication duration range based on the communication duration. Then, the electronic device compares the transmission duration with the communication duration range. If it determines that the transmission duration is within the communication duration range, it indicates that the single batch of communication data of the target terminal can be stored within the time from the current moment until the target terminal leaves the first communication range. Therefore, the electronic device generates a storage instruction.

[0060] Step S102, based on the first relative position relationship, generates a storage instruction and determines the target satellite, including: acquiring the operation information corresponding to multiple candidate satellites that establish an initial connection with the target terminal, and determining the second communication range and first operating direction corresponding to the multiple candidate satellites based on the operation information; acquiring the second operating direction of the target terminal when the first relative position relationship satisfies the generation of the storage instruction; and determining the target satellite from the multiple candidate satellites based on the target position, the first operating direction, the second operating direction, and the second communication range.

[0061] In some embodiments, the electronic device determines the second communication range and the first direction of operation for each candidate satellite from the operation information corresponding to the multiple candidate satellites. The second communication range is the range within which the candidate satellite can provide high-quality and stable communication services to the target terminal. When the first relative positional relationship satisfies the generation and storage instruction, it indicates that the work of determining the target satellite from the multiple candidate satellites can begin. Subsequently, the electronic device obtains the second direction of operation of the target terminal. Then, the target position, the first direction of operation, the second direction of operation, and the second communication range are used as the basic parameters for determining the target satellite from the multiple candidate satellites to determine the target satellite that meets the requirements for providing communication services to the target terminal.

[0062] In some embodiments, determining a target satellite from a plurality of candidate satellites based on a target location, a first direction of travel, a second direction of travel, and a second communication range includes: determining distance information of the target terminal leaving the plurality of second communication ranges based on the target location, the first direction of travel, and the second direction of travel; determining a second relative speed between the target terminal and the plurality of candidate satellites; determining the dwell time of the target terminal within the plurality of second communication ranges based on the distance information and the second relative speed; determining the second communication range corresponding to the longest dwell time as the target second communication range, and determining the candidate satellite corresponding to the target second communication range as the target satellite.

[0063] In some embodiments, the electronic device uses the target location as a reference point and determines the distance information of the target terminal leaving each of the second communication ranges based on the first and second running directions. Subsequently, the electronic device acquires the running speed of each candidate satellite and determines the second relative running speed between the target terminal and each candidate satellite based on the running speed. Then, by calculating the distance information and the second relative running speed, the dwell time of the target terminal in each second communication range is determined, thus obtaining multiple dwell times.

[0064] Subsequently, the electronic device compares multiple dwell times, selects the longest dwell time from the multiple dwell times, determines the second communication range corresponding to the longest dwell time as the target second communication range, and determines the candidate satellite corresponding to the target second communication range as the target satellite that meets the requirements for providing communication services to the target terminal.

[0065] In some embodiments, the preset location point is the edge point of the first communication range. Then, in step S103, when the target location is located at the preset location point of the first communication range and the communication information storage completion information is obtained based on the storage instruction, a communication switching instruction and an information sending instruction are generated. This includes: when the target location is located at the edge point and the communication information storage completion information is obtained based on the storage instruction, the storage information and the time information corresponding to the storage information are obtained, and the storage information and the time information are integrated to obtain the information sending instruction.

[0066] In some embodiments, the stored information is the target communication information sent by the target terminal. To avoid the time node error between the stored information sent to the target satellite and the communication information of the target terminal previously received by the initial satellite, when the electronic device is located at the edge of the first communication range and has obtained the communication information storage completion information, the electronic device obtains the stored information and its corresponding time information from the storage device, and integrates the stored information and its corresponding time information to obtain the information sending instruction.

[0067] This application provides a direct satellite communication device, which adopts the following technical solution:
