Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of satellite communication, in particular to a constellation-based direct connection communication method and device, electronic equipment and storage medium. BACKGROUND

[0002] With the continuous development of low-orbit satellite direct connection communication technology, the application of low-orbit satellite direct connection communication is becoming more and more widespread, which has gradually shifted from emergency direct connection communication services in special environments to ordinary direct connection communication services in traditional environments. In emergency direct connection communication services in special environments, the data of target terminals is usually less, and single-to-single direct connection and communication are generally used when communicating with target satellites. However, in ordinary direct connection communication services in traditional environments, the number of target terminals is large, and at this time, it is necessary to consider the application constellation covering these target terminals for unified batch communication connection and communication services.

[0003] However, in ordinary direct connection communication services in traditional environments, due to the large number of target terminals and uneven distribution, the efficiency of establishing communication connection and communication services between multiple satellites in the constellation and target terminals will be reduced due to the number and distribution of target terminals.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0034] 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.

[0035] This application provides a constellation-based direct communication method that can be executed by an electronic device, wherein 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, or on a high-orbit satellite, or on a low-orbit satellite.

[0036] Reference Figure 1 A constellation-based direct communication method includes steps S101, S102, S103 and S104, wherein, in S101, the location information and historical communication information corresponding to multiple target communication areas are obtained respectively, and the distribution relationship between multiple target communication areas is determined based on the multiple location information.

[0037] In some embodiments, the target communication area is the area in which multiple satellites in a constellation simultaneously provide direct terminal communication services; the location information is the regional location information of the target communication area; the historical communication information is information that characterizes the communication status of the target terminal in the target communication area within a previously preset time period; and the distribution relationship characterizes the distribution among multiple target communication areas.

[0038] The electronic device acquires the constellation's communication tasks and analyzes them to determine the initial communication area where the constellation is responsible for direct communication. It then identifies multiple target communication areas within this initial area that require direct terminal communication services from the constellation. Subsequently, the electronic device generates an information acquisition command and sends it to a storage terminal containing historical communication information corresponding to each of the target communication areas. The storage terminal responds to the command by sending the historical communication information for each target communication area back to the electronic device. Simultaneously, the electronic device sends the information acquisition command to high-orbit satellites covering the multiple target communication areas. These high-orbit satellites respond to the command by sending the acquired location information of the target communication areas back to the electronic device. The electronic device then compares and analyzes these location information sets to determine the distribution relationship among the target communication areas.

[0039] S102, based on distribution relationships and historical communication information, determines the criteria for selecting target satellites.

[0040] In some embodiments, the satellite selection criteria are criteria for selecting target satellites responsible for providing direct terminal communication services to target communication areas that exhibit different distribution relationships.

[0041] The distribution relationship can be discrete or clustered. A discrete distribution relationship indicates that the target communication areas are far apart, and due to the limited coverage of low-Earth orbit satellites, a single satellite cannot simultaneously provide direct terminal communication services to multiple target communication areas. Conversely, a clustered distribution relationship indicates that the target communication areas are close together or adjacent, allowing a single satellite to provide direct terminal communication services to multiple close or adjacent target communication areas. Therefore, from multiple candidate satellites in the constellation, target satellites providing direct terminal communication services to multiple target communication areas are selected. Electronic equipment can determine the target satellite selection criteria based on the distribution relationship and historical communication information.

[0042] S103, based on the target satellite selection criteria, selects target satellites and applicable beam resources corresponding to multiple target communication areas from multiple candidate satellites.

[0043] In some embodiments, the applicable beam resources are the beam resources provided by the target satellite when it provides direct terminal communication services to its corresponding target communication area.

[0044] The electronic equipment acquires the communication resource quantity of multiple candidate satellites in the constellation, and then selects the target satellite corresponding to each target communication area from the multiple candidate satellites based on the target satellite selection criteria, and uses the communication resource quantity to determine the applicable beam resources corresponding to each target satellite.

[0045] S104, based on applicable beam resources and generated communication service instructions, controls the target satellite to provide communication services for its corresponding target communication area.

[0046] In some embodiments, the electronic device generates a communication service instruction and sends the applicable beam resources corresponding to each target satellite and the generated communication service instruction to each target satellite. The target satellite responds to the communication service instruction and provides direct communication services to the target communication area corresponding to it based on the applicable beam resources. In this way, by uniformly and appropriately allocating the beam communication resources of the constellation satellites, multiple satellites in the constellation can simultaneously and use reasonable beam communication resources to provide direct communication services to target terminals in their respective target areas, thereby improving the direct communication efficiency of the constellation satellites.

[0047] In some embodiments, before obtaining the location information and historical communication information corresponding to the multiple target communication areas in step S101, the constellation-based direct communication method further includes: obtaining the area information corresponding to the initial communication area, and determining the communication terminal distribution information and distribution density information based on the area information; dividing the initial communication area into multiple initial communication areas based on the distribution information and distribution density information; obtaining the communication transmission volume per unit time corresponding to the multiple initial communication areas; and determining the initial communication area corresponding to the communication transmission volume exceeding the preset communication transmission volume as the target communication area.

[0048] In some embodiments, the communication terminal distribution information is a representation of the distribution of target terminals located within the initial communication area; the distribution density information is the number of target terminals within a preset unit area in the initial communication area.

[0049] The electronic device first analyzes the acquired communication task to determine the initial communication area where the constellation needs to provide direct terminal communication services and obtains the area information corresponding to the initial communication area. Then, the electronic device analyzes the location information of the target terminals contained in the area information to determine the distribution information and distribution density information of the communication terminals corresponding to the initial communication area. Based on the distribution information, the electronic device performs a preliminary division of the initial communication area, removing areas within the initial communication area where no target terminals exist, resulting in a preliminary division of the initial communication area. Subsequently, the electronic device calls the preset distribution density area division rules to further divide the preliminary initial communication area, determining multiple initial communication areas.

[0050] The electronic device acquires the preset communication transmission volume per unit time corresponding to each initial communication area and compares the communication transmission volume with the preset communication transmission volume. If the electronic device determines that any communication transmission volume is greater than the preset communication transmission volume, it indicates that there are a large number of terminals in the initial communication area corresponding to that communication transmission volume that need to establish direct terminal communication. The target satellite can then establish a unified communication connection and provide direct terminal communication services. Subsequently, the electronic device determines the initial communication area corresponding to that communication transmission volume as the target communication area.

[0051] If an electronic device determines that a certain communication transmission volume among multiple communication transmission volumes is not greater than a preset communication transmission volume, it indicates that the number of devices requiring direct terminal communication within the initial communication area corresponding to that communication transmission volume is small or the communication data is small. Therefore, there is no need to establish a unified communication connection or provide direct terminal communication services. Consequently, the electronic device will not use the initial communication area corresponding to that communication transmission volume as the target communication area.

[0052] In step S101, determining the distribution relationship between multiple target communication areas based on multiple location information includes: determining multiple edge points corresponding to each of the multiple target communication areas based on the area location information, and determining the corresponding distance between two adjacent target communication areas based on the multiple edge points; if the distance is greater than a preset distance, determining the distribution relationship between two adjacent target communication areas as a discrete distribution relationship; if the distance is not greater than the preset distance, determining the distribution relationship between two adjacent target communication areas as a clustered distribution relationship.

[0053] In some embodiments, the electronic device determines multiple edge points corresponding to each target communication region based on regional location information. Each edge point is the closest edge point between its corresponding target communication region and other adjacent target communication regions. Subsequently, the electronic device uses these edge points to determine the distance between two adjacent target communication regions. The electronic device compares this distance with a preset distance. If the distance is greater than the preset distance, it indicates that the two adjacent target communication regions do not intersect and are far apart. The electronic device then determines the distribution relationship between the two adjacent target communication regions as a discrete distribution relationship. If the distance is not greater than the preset distance, it indicates that the two adjacent target communication regions are close together or their edge points overlap. The electronic device then determines the distribution relationship between the two adjacent target communication regions as a clustered distribution relationship.

[0054] In some embodiments, if the distribution relationship between any target communication area and the other two target communication areas in a plurality of target communication areas is a clustered distribution relationship, then any target communication area and the other two target communication areas can be constructed as a whole as a large target communication area.

[0055] Step S102, based on the distribution relationship and historical communication information, determines the target satellite selection criteria, including: when the distribution relationship between at least two target communication areas of multiple target communication areas is a discrete distribution relationship, determining the unit communication transmission volume based on the historical communication information corresponding to the at least two target communication areas respectively; and determining the target satellite selection criteria corresponding to the at least two target communication areas as the first target satellite selection criterion based on the unit communication transmission volume, wherein the first target satellite selection criterion is a selection criterion in which the area and the satellite correspond one-to-one and the satellite communication resources are adaptively matched with the unit communication transmission volume of the area.

[0056] In some embodiments, when the distribution relationship between at least two of the multiple target communication areas is discrete, since the at least two target areas are far apart and the amount of data of the target terminals requiring terminal quality communication or the amount of data to be transmitted in each target communication area is large, it can be considered that each target communication area is provided with direct terminal communication service by its specific target satellite. Then, the electronic device determines the unit communication transmission volume corresponding to each target communication area based on the historical communication information corresponding to the at least two target communication areas respectively. The unit communication transmission volume is the communication transmission volume when the maximum number of target terminals in the target communication area communicates for data transmission or the maximum amount of data transmission per unit time. Subsequently, after determining the unit communication transmission volume, the electronic device further determines the selection criterion of the target satellites corresponding to the at least two target communication areas as the first target satellite selection criterion. The electronic device uses the first target satellite selection criterion to select the specific target satellites for the at least two target communication areas and matches the satellite communication resources corresponding to the target satellites for the target communication areas.

[0057] Step S102, based on distribution relationships and historical communication information, determines the target satellite selection criteria, including: when the distribution relationship between at least two target communication areas in multiple target communication areas is a clustered distribution relationship, determining the total unit communication transmission volume corresponding to at least two target communication areas based on historical communication information; and determining the target satellite selection criteria corresponding to at least two target communication areas as the second target satellite selection criteria based on the total unit communication transmission volume, wherein the second target satellite selection criteria is the correspondence between a single satellite and multiple areas, and the selection criteria are based on the adaptive matching of satellite communication resources and total unit communication transmission volume.

[0058] In some embodiments, when at least two of the target communication areas in a plurality of target communication areas have a clustered distribution relationship, since the at least two target communication areas are close to each other or their edge points overlap, it is possible to consider integrating the at least two target communication areas into a larger target communication area and determining its corresponding target satellite to provide direct terminal communication services. Subsequently, the electronic device determines the unit communication transmission volume corresponding to each target communication area based on the historical communication information corresponding to the at least two target communication areas respectively, and then accumulates the at least two unit communication transmission volumes to obtain the total unit communication transmission volume. Subsequently, the electronic device determines the total unit communication transmission volume and determines the target satellite screening criteria corresponding to the at least two target communication areas as the second target satellite screening criteria. The electronic device uses the second target satellite screening to screen specific target satellites for the larger target communication area constructed from the at least two target communication areas and matches the satellite communication resources corresponding to the target satellites for the larger target communication areas.

[0059] Step S103, based on the target satellite selection criteria, select target satellites corresponding to multiple target communication areas and applicable beam resources corresponding to the target satellites from multiple candidate satellites, including: when the satellite selection criterion is the second target satellite selection criterion, select the maximum communication resource quantity from the communication resource quantities corresponding to the multiple candidate satellites; when the total unit communication transmission volume of at least two target communication areas corresponding to the second target satellite selection criterion is not greater than the maximum communication resource quantity, and the difference between the maximum communication resource quantity and the total unit communication transmission volume is not greater than a preset difference, determine the candidate satellite corresponding to the maximum communication resource quantity as the target satellite, and determine the maximum communication resource quantity as the applicable beam resource.

[0060] In some embodiments, when the target satellite selection criterion is the second target satellite selection criterion, the electronic device obtains the corresponding communication resource quantity from multiple candidate satellites, compares the multiple communication resource quantities, determines the maximum communication resource quantity, and then compares the maximum communication resource quantity with the total unit communication transmission of at least two target communication areas corresponding to the second target satellite selection criterion. If it is determined that the total unit communication transmission quantity is not greater than the maximum communication resource quantity, it indicates that the candidate satellite corresponding to the maximum communication resource quantity has the ability to independently provide terminal direct communication services for at least two target communication areas. Subsequently, the electronic device determines the candidate satellite corresponding to the maximum communication resource quantity as the target satellite and uses the maximum communication resource quantity of the target satellite as the applicable beam resource.

[0061] When the electronic device determines that the total unit communication transmission volume is greater than the maximum communication resource volume, it indicates that the candidate satellite corresponding to the maximum communication resource volume does not have the capability to independently provide direct terminal communication services for at least two target communication areas. Subsequently, the electronic device determines the difference between the maximum communication resource volume and the total unit communication transmission volume, and selects a candidate satellite that matches the difference from multiple candidate satellites based on the difference, and uses this candidate satellite as the target satellite. The electronic device then controls the target satellite and the target satellite corresponding to the maximum communication resource volume to simultaneously provide direct terminal communication services for at least two target communication areas.

[0062] In some embodiments, after controlling the target satellite to provide communication services to its corresponding target communication area based on the applicable beam resources and the generated communication service command in step S104, the constellation-based direct communication method further includes: when the communication congestion information corresponding to the target satellite is obtained, determining the communication difference between the target satellite and the target communication area; when the communication difference is greater than a preset communication difference, generating a communication transmission command, and controlling the candidate satellite to receive the communication data corresponding to the communication difference based on the communication transmission command.

[0063] In some embodiments, when an electronic device controls a target satellite to provide communication services to its corresponding target communication area, if the electronic device obtains communication congestion information corresponding to the target satellite, it indicates that the target communication area is experiencing a greater number of target terminals transmitting communication data than the previous maximum number of target terminals, or a larger data volume than the previous maximum data volume. At this time, the target satellite cannot provide stable and efficient direct terminal communication services to the target communication area. Subsequently, the electronic device obtains the current communication data volume of the target communication area and calculates the difference between the current communication data volume and the communication resource volume of the target satellite to obtain the communication difference.

[0064] Subsequently, the electronic device compares the communication difference with the preset communication difference. If it determines that the communication difference is greater than the preset communication difference, it indicates that the amount of communication data to be transmitted in the target communication area cannot be reduced in a short time. It is necessary to consider using alternative satellites to provide communication support for the target communication area. Then, the electronic device generates a communication transmission command and controls the alternative satellite to receive the communication data corresponding to the communication difference based on the communication transmission command. The alternative satellite can be a low-Earth orbit satellite in the constellation or a high-Earth orbit satellite that can cover the target communication area.

[0065] This application provides a constellation-based direct communication device, which adopts the following technical solution:
