Technical Field

[0002] With the continuous development of low-Earth orbit (LEO) satellite technology, the technology for providing direct communication services to users via LEO satellites is becoming increasingly mature. Furthermore, due to the advantages of LEO satellites, such as low operating altitude, high operating speed, and high communication quality, the use of LEO satellites to provide direct communication services to users is becoming increasingly common, such as providing communication services to users in urban areas, remote mountainous areas, or special areas.

[0003] However, the inventors of this application have discovered that when low-orbit satellites provide communication services to users in remote mountainous areas or special regions, users have high requirements for the stability and quality of communication and low tolerance for co-channel interference. In this case, when the target satellite provides communication services to users in the region, the beam range of other satellites may still overlap with the beam range of the target satellite, causing users in the overlapping area to be affected by co-channel interference, resulting in a decrease in communication stability and quality.

[0045] Reference Figure 1 A satellite communication method for beam overlap regions includes steps S101, S102, and S103, wherein...

[0046] S101, Obtain the area information corresponding to the beam overlap area.

[0047] In some embodiments, the first target satellite moves to the target area where communication services need to be provided, and the first beam range of the first target satellite includes the target area. During 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. The other satellites are satellites with different operating directions from the first target satellite, and the other satellites are satellites with the same frequency as the first target satellite.

[0048] If any of the other satellites moves within a preset range, that satellite is defined as the second target satellite, and its operation is monitored in real time. If 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 overlap area between the first and second target satellites and obtain its corresponding area information. Subsequently, based on the area information, a beam adjustment scheme for the beam overlap area is determined, and the satellite provides communication services to users in the overlap area based on the adjusted beam.

[0049] S102, determine the beam overlap region division rules corresponding to the region information, and divide the beam overlap region based on the beam overlap region division rules to obtain at least two sub-beam overlap regions.

[0050] In some embodiments, the region information includes the location information of the edge line of the first beam range and the location information of the edge line of the second beam range, wherein the edge line is the edge line that constitutes the beam overlap region.

[0051] The electronic device analyzes and compares 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 to determine the beam overlap region division rule corresponding to the overlapping region. Then, the electronic device uses the beam overlap region division rule to divide the beam overlap region and determine at least two sub-beam overlap regions.

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

[0053] In some embodiments, since the at least two sub-beam overlapping regions are located at different positions within the first beam range, the degree of co-channel interference from the second target satellite varies among the at least two sub-beam overlapping regions. That is, the sub-beam overlapping regions closer to the edge of the first beam range are more severely affected by the co-channel interference from the second target satellite. Therefore, the electronic device generates a power adjustment command for the first target satellite corresponding to each of the at least two sub-beam overlapping regions. Subsequently, based on the power adjustment command, the electronic device adjusts the beam power of the first target satellite corresponding to the at least two sub-beam overlapping regions, so that the first target satellite can provide communication services to users within 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 within the inter-satellite beam overlapping regions.

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

[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 operating directions from the first target satellite and obtains its second beam range. Subsequently, the electronic device compares the positions of the first beam range and the second beam range to determine the positional relationship between the first beam range and the second beam range, and makes a judgment on the positional relationship.

[0056] When the electronic device determines that there is a beam overlap area between the first beam range and the second beam range, it indicates that users in the overlap area will be subject to co-frequency interference from the second target satellite. Subsequently, 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 overlap area. The area information includes the position information of the edge line constituting the overlap area, as well as the position information of multiple edge points of the edge line.

[0057] In step S402, determining the beam overlap region division rule corresponding to the region information includes: determining the first distance information corresponding to the beam overlap region based on the region information, wherein the first distance information is the distance information between the first target edge point of the first beam range and the first target edge point of the second beam range; obtaining the user distribution information of users within the beam overlap region; and determining the beam overlap region 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 multiple edge points contained in the edge line. The two first target edge points are respectively the edge points of the first beam range and the edge points of the second beam range. Subsequently, the electronic device connects the two first target edge points and defines the connected line segment as the first distance information. At the same time, the electronic device acquires the location information of all users in the beam overlap area and analyzes the location information of all users to obtain user distribution information. The electronic device determines the beam overlap area division rules based on the first distance information and the user distribution information.

[0059] In some embodiments, determining a beam overlap region division rule based on first distance information and user distribution information includes: determining a first beam overlap region division rule when the first distance information satisfies preset distance information and the user distribution information satisfies a first preset distribution information, wherein the first preset distribution information is that users are evenly distributed within the overlap region; and determining a second beam overlap region division rule when the first distance information satisfies preset distance information and the user distribution information satisfies a second preset distribution information, wherein the second preset distribution information is that users are concentratedly distributed within the overlap region.

[0060] In some embodiments, the beam overlap region division rules include a first beam overlap region division rule and a second beam overlap region division rule, which are constructed in advance by the electronic device before obtaining the region information corresponding to the beam overlap region; after obtaining the first distance information and 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 meets the preset distance information, it indicates that the area 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 meets the first preset distribution information, it indicates that the users in the beam overlap area are uniformly distributed. Subsequently, the electronic device determines the beam overlap area division rule as the first beam overlap area division rule, wherein the first beam overlap area division rule is a rule that divides the beam overlap area into at least two sub-beam overlap areas uniformly based on the preset distance.

[0062] When the electronic device determines that the user distribution information meets the second preset distribution information, it indicates that the users in the beam overlap area are concentrated. Then, the electronic device determines the beam overlap area division rule as the second beam overlap area division rule, which is a rule that divides the concentrated users as a whole.

[0063] In step S402, the beam overlap region is divided based on the beam overlap region division rule to obtain at least two sub-beam overlap regions, including: when the beam overlap region division rule is the first beam overlap region 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 regions from the virtual circle and the beam overlap region; and defining the at least two virtual closed regions as at least two sub-beam overlap regions.

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

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

[0066] In some embodiments, during the process of adjusting the satellite beam power of at least two sub-beam overlap regions that characterize at least two virtual enclosed regions, since the region 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 overlap region closer to the edge of the first beam range is greater than the adjusted beam power corresponding to the sub-beam overlap region not close to the edge of the first beam range, so as to improve the communication quality of users in the sub-beam overlap region closer to the edge of the first beam range.

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

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

[0069] In some embodiments, during the satellite power beam adjustment process for at least two sub-beam overlap regions representing concentrated and non-concentrated distribution areas, the power of the adjusted beam corresponding to the concentrated distribution area is greater than that of the adjusted beam corresponding to the non-concentrated distribution area because the number of users in the concentrated distribution area is large, thereby improving the communication quality of users in the concentrated distribution area.

[0070] In some embodiments, the satellite communication method for beam overlap regions described above further 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 third preset distance information, and determining the beam influence region based on the third preset distance information; generating a second target satellite power adjustment command corresponding to the beam influence region, and adjusting the beam power of the first target satellite corresponding to the beam influence region based on the second target satellite power adjustment command.

[0071] In some embodiments, the electronic device compares the first beam range and the second beam range, and determines that there is no beam overlap area between the first beam range and the second beam range. However, if the edge points of the second target coincide between the two, it indicates that the edge area of ​​the first beam range closer to the second beam range will be subject to co-frequency interference from the second target satellite. Subsequently, the electronic device calls the third preset distance information, and constructs a virtual area corresponding to the second beam range with the third preset distance information as the radius and the circle of the second beam range as the reference. Then, the area constructed by the virtual area and the first beam range is defined as the beam influence area. The electronic device generates the second target power adjustment command 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 command.

[0072] In some embodiments, such as Figure 3 As shown, the second target edge point 33 between the first beam range 31 and the second beam range 32 coincides. The electronic device calls the third preset distance information 34, and constructs a virtual region 36 corresponding to the second beam range 32 with the third preset distance information 34 as the radius and the second circle point 35 of the second beam range 32 as the reference. Then, the region constructed by the virtual region 36 and the first beam range 31 is defined as the beam influence region 37. The electronic device generates the second target power adjustment command corresponding to the beam influence region 37, and adjusts the beam power of the first target satellite corresponding to the beam influence region 37 based on the second target satellite power adjustment command.
