DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the drawings in the embodiments of the present application are collected below to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] An embodiment of the present application provides a satellite communication method in a beam overlapping area, which can be executed by an electronic device, wherein the electronic device can be a server, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server that provides cloud computing services; the server can be installed in a ground communication terminal.

[0045] Reference Figure 1 A satellite communication method in a beam overlap region includes: step S101, step S102 and step S103, wherein:

[0046] S101, obtaining area information corresponding to the beam overlapping area.

[0047] In some embodiments, the first target satellite moves to a target area that needs to provide communication services. At this time, the first beam range of the first target satellite includes the target area. In the process of the first target satellite providing communication services to the target area, the movement of the first beam range of the first target satellite and the movement of the beam ranges of other satellites are monitored in real time, wherein the other satellites are satellites with a different movement direction from the first target satellite, and the other satellites are satellites of the same frequency as the first target satellite.

[0048] When any satellite among the other satellites operates within a preset range, the any satellite is defined as a second target satellite, and the operation of the second target satellite is monitored in real time. When the second beam range of the second target satellite overlaps with the first beam range, it indicates that the second target satellite will cause co-channel interference to the communication of the first target satellite. In order to reduce the impact of co-channel interference on the communication of the first target satellite, it is necessary to determine the beam overlapping area between the first target satellite and the second target satellite and obtain the corresponding area information, and then determine the beam adjustment plan of the beam overlapping area based on the area information, and the satellite provides communication services to users in the overlapping area based on the adjusted beam.

[0049] S102, determining a beam overlapping region division rule corresponding to the region information, and dividing the beam overlapping region based on the beam overlapping region division rule to obtain at least two sub-beam overlapping regions.

[0050] In some embodiments, the region information includes position information of edge lines of the first beam range and position information of edge lines of the second beam range, wherein the edge lines are edge lines constituting the beam overlap region.

[0051] The electronic device determines a beam overlap area division rule corresponding to the overlap area by analyzing and comparing the position information of the edge line of the first beam range and the position information of the edge line of the second beam range. Subsequently, the electronic device divides the beam overlap area into regions using the beam overlap area division rule to determine at least two sub-beam overlap regions.

[0052] S103, generate first target satellite power adjustment instructions corresponding to at least two sub-beam overlapping areas respectively, and based on the first target satellite power adjustment instructions, adjust the beam power of the first target satellite corresponding to at least two sub-beam overlapping areas, so that the first target satellite provides communication services to users based on the power-adjusted beam.

[0053] In some embodiments, since at least two sub-beam overlapping regions are located at different positions within the first beam range, the at least two sub-beam overlapping regions are affected by the co-channel interference of the second target satellite to different degrees, that is, the sub-beam overlapping regions that are closer to the edge of the first beam range are more seriously affected by the co-channel interference of the second target satellite. Therefore, the electronic device generates a first target satellite power adjustment instruction corresponding to each of the at least two sub-beam overlapping regions. Subsequently, the electronic device adjusts the beam power of the first target satellite corresponding to the at least two sub-beam overlapping regions based on the first target satellite power adjustment instruction, so that the first target satellite can provide communication services to users in the at least two sub-beam overlapping regions with the power-adjusted beam, thereby reducing the impact of co-channel interference on the satellite communication quality of users in the inter-satellite beam overlap region.

[0054] In step S401, area information corresponding to the beam overlapping area is obtained, including: obtaining a first beam range of a first target satellite and a second beam range of a second target satellite; determining a positional relationship between the first beam range and the second beam range; and when the positional relationship is such that there is a beam overlapping area between the first beam range and the second beam range, obtaining area information corresponding to the beam range overlapping area.

[0055] In some embodiments, the electronic device monitors the first beam range of the first target satellite in real time. When the first beam range includes the target area, the electronic device selects the second target satellite from multiple other satellites with different moving directions from the first target satellite, and obtains its second beam range; then, the electronic device compares the positions of the first beam range and the second beam range, determines the positional relationship between the first beam range and the second beam range, and judges the positional relationship.

[0056] When the electronic device determines that there is a beam overlapping area between the position relationship of the first beam range and the second beam range, it indicates that users in the overlapping area will be affected by the co-frequency interference of the second target satellite. Then, the electronic device compares and analyzes the position information of the first beam range and the position information of the second beam range to obtain the area information corresponding to the beam overlapping area, wherein the area information includes the position information of the edge line constituting the overlapping area, and also includes the position information of multiple edge points of the edge line.

[0057] In step S402, a beam overlapping area division rule corresponding to the area information is determined, including: based on the area information, determining first distance information corresponding to the beam overlapping area, wherein the first distance information is distance information between a first target edge point of the first beam range and a first target edge point of the second beam range; obtaining user distribution information of users in the beam overlapping area; and determining a beam overlapping area division rule based on the first distance information and the user distribution information.

[0058] In some embodiments, the electronic device analyzes the area information and determines two first target edge points from the multiple edge points contained in the edge line, wherein the two first target edge points are edge points of the first beam range and the edge points of the second beam range, respectively. Subsequently, the electronic device connects the two first target edge points and defines the connected line segment as first distance information; at the same time, the electronic device obtains the location information of all users in the beam overlapping area, and analyzes the location information of all users to obtain user distribution information; the electronic device determines the beam overlapping area division rules based on the first distance information and the user distribution information.

[0059] In some embodiments, based on the first distance information and the user distribution information, a beam overlapping area division rule is determined, including: when the first distance information satisfies the preset distance information and the user distribution information satisfies the first preset distribution information, the beam overlapping area division rule is determined to be the first beam overlapping area division rule, wherein the first preset distribution information is that users are uniformly distributed in the overlapping area; when the first distance information satisfies the preset distance information and the user distribution information satisfies the second preset distribution information, the beam overlapping area division rule is determined to be the second beam overlapping area division rule, wherein the second preset distribution information is that users are concentratedly distributed in the overlapping area.

[0060] In some embodiments, the beam overlapping area division rules include a first beam overlapping area division rule and a second beam overlapping area division rule, which are constructed in advance by the electronic device before obtaining the area information corresponding to the beam overlapping area; after the electronic device obtains the first distance information and the user distribution information, the electronic device compares the first distance information with the preset distance information to determine whether the first distance information meets the preset distance information.

[0061] When the electronic device determines that the first distance information satisfies the preset distance information, it indicates that the range affected by the co-channel interference of the second target satellite is large; at the same time, the electronic device compares the user distribution information with the first preset distribution information; when the electronic device determines that the user distribution information satisfies the first preset distribution information, it indicates that the users in the beam overlapping area are uniformly distributed, and then the electronic device determines that the beam overlapping area division rule is the first beam overlapping area division rule, wherein the first beam overlapping area division rule is a rule for uniformly dividing the beam overlapping area into at least two sub-beam overlapping areas based on the preset distance.

[0062] When the electronic device determines that the user distribution information satisfies the second preset distribution information, it indicates that the users in the beam overlapping area are distributed in a concentrated manner. Then, the electronic device determines that the beam overlapping area division rule is the second beam overlapping area division rule, wherein the second beam overlapping area division rule is a rule for dividing the users in a concentrated manner as a whole.

[0063] In step S402, the beam overlapping area is divided based on the beam overlapping area division rule to obtain at least two sub-beam overlapping areas, including: when the beam overlapping area division rule is the first beam overlapping area division rule, calling the second preset distance information to construct a virtual circle corresponding to the first beam range; constructing at least two virtual closed areas by the virtual circle and the beam overlapping area, and defining the at least two virtual closed areas as at least two sub-beam overlapping areas.

[0064] In some embodiments, when the beam overlapping area division rule is the first beam overlapping area division rule, it indicates that the users in the beam overlapping area are uniformly distributed. Then, the electronic device calls the second preset distance information, and uses the second preset distance information as the radius and the center of the first beam range as the basis to construct a virtual circle. Subsequently, at least two virtual closed areas are constructed by the virtual circle and the beam overlapping area, and the at least two virtual closed areas are defined as at least two sub-beam overlapping areas.

[0065] For example, refer to Figure 2 There is a beam overlapping area 23 between the first beam range 21 and the second beam range 22. The electronic device calls the second preset distance information 24, takes the second preset distance information 24 as the radius, and constructs a virtual circle 26 based on the first center 25 of the first beam range 21. Subsequently, two virtual closed areas 27 are constructed by the virtual circle 26 and the beam overlapping area 23, and the two virtual closed areas 27 are defined as two sub-beam overlapping areas.

[0066] In some embodiments, in the process of adjusting the satellite beam power of at least two sub-beam overlapping areas representing at least two virtual closed areas, since the area closer to the edge of the first beam range is more affected by co-channel interference, the adjusted beam power corresponding to the sub-beam overlapping area close to the edge of the first beam range is greater than the adjusted beam power corresponding to the sub-beam overlapping area not close to the edge of the first beam range, so as to improve the communication quality of users in the sub-beam overlapping area close to the edge of the first beam range.

[0067] In step S402, the beam overlapping area is divided based on the beam overlapping area division rule to obtain at least two sub-beam overlapping areas, including: when the beam overlapping area division rule is the second beam overlapping area division rule, determining the location information of at least three target users, wherein the target users are edge users in a concentrated distribution range within the beam overlapping area; based on the location information of at least three target users, constructing a concentrated distribution area, and defining the concentrated distribution area and the non-concentrated distribution area as at least two sub-beam overlapping areas.

[0068] In some embodiments, when the electronic device determines that the beam overlap area division rule is the second beam overlap area division rule, it indicates that the users in the beam overlap area are distributed in a concentrated manner. Then, the electronic device determines the location information of three target users from all users in the beam overlap, and uses the location information as the edge point of the concentrated distribution area to construct a concentrated distribution area, wherein the concentrated distribution area is a circular area. Subsequently, the electronic device defines the concentrated distribution area and the non-concentrated distribution area as at least two sub-beam overlap areas.

[0069] In some embodiments, during the satellite power beam adjustment process for at least two sub-beam overlapping areas representing concentrated distribution areas and non-concentrated distribution areas, due to the large number of users in the concentrated distribution area, the power of the adjusted beam corresponding to the concentrated distribution area is greater than the power of the adjusted beam corresponding to the non-concentrated distribution area, so as to improve the communication quality of users in the concentrated distribution area.

[0070] In some embodiments, the above-mentioned satellite communication method for beam overlapping areas also includes: when the first beam range of the first target satellite and the second beam range of the second target satellite do not overlap, and the second target edge point of the first beam range and the second target edge point of the second beam range overlap, calling the third preset distance information, and determining the beam influence area based on the third preset distance information; generating a second target satellite power adjustment instruction corresponding to the beam influence area, and adjusting the beam power of the first target satellite corresponding to the beam influence area based on the second target satellite power adjustment instruction.

[0071] In some embodiments, the electronic device compares the first beam range and the second beam range, and determines that there is no beam overlapping area between the first beam range and the second beam range, but when the second target edge points between the two coincide, it indicates that the edge area of ​​the first beam range close to the second beam range will be subject to the co-frequency interference of the second target satellite. Then, the electronic device calls the third preset distance information, and uses the third preset distance information as the radius and the dot of the second beam range as the reference to construct a virtual area corresponding to the second beam range. Subsequently, the area constructed by the virtual area and the first beam range is defined as the beam influence area; the electronic device generates a second target power adjustment instruction corresponding to the beam influence area, and adjusts the beam power of the first target satellite corresponding to the beam influence area based on the second target satellite power adjustment instruction.

[0072] In some embodiments, for example, Figure 3 As shown, the second target edge point 33 between the first beam range 31 and the second beam range 32 overlaps, the electronic device calls the third preset distance information 34, and uses the third preset distance information 34 as the radius and the second dot 35 of the second beam range 32 as the reference to construct a virtual area 36 corresponding to the second beam range 32, and then defines the area constructed by the virtual area 36 and the first beam range 31 as the beam influence area 37; the electronic device generates a second target power adjustment instruction corresponding to the beam influence area 37, and adjusts the beam power of the first target satellite corresponding to the beam influence area 37 based on the second target satellite power adjustment instruction.
