[0022] In addition, it should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0023] First, the terms involved in one or more embodiments of this specification are explained.

[0024] Satellite: refers to a natural celestial body that orbits a planet and moves periodically in a closed orbit. Artificial satellites are also generally called satellites. Artificial satellites are artificially built and launched into space by space flight vehicles such as rockets and spacecraft. They orbit the earth or other planets like natural satellites.

[0025] Low-orbit satellite system: generally refers to a large satellite system composed of multiple satellites that can perform real-time information processing. The distribution of satellites is called a satellite constellation. Low-orbit satellites are mainly used for military target detection. It is easy to obtain high-resolution images of the target using low-orbit satellites. Low-orbit satellites can also be used for mobile phone communications. The low orbit height of the satellite makes the transmission delay short and the path loss small. The communication system composed of multiple satellites can achieve true global coverage, and frequency reuse is more effective. Cellular communication, multiple access, spot beam, frequency reuse and other technologies also provide technical support for low-orbit satellite mobile communications. The low-orbit satellite constellation consists of multiple low-orbit satellites on multiple orbits. Since the low-orbit satellites are not synchronized with the earth, the constellation is constantly changing, and the relative positions of each low-orbit satellite are also constantly changing.

[0026] In practical applications, the characteristics of satellite communication systems are that both the communication terminals and communication satellites in the system are movable. Due to the fast movement speed of low-orbit satellites, the satellite communication system composed of low-orbit satellites can provide better communication services to ground communication terminals. Satellite communication terminals can plan and schedule the communication beam resources of communication satellites to complete the coverage of ground signals according to the coordinate system of the fixed satellite beam gaze on the ground. However, the ground coordinate system is composed of grids of equal size (such as triangles, hexagons, circles, etc.), which can be used to enable communication terminals to locate their own positions. The coverage area of ​​the wave position of the communication satellite beam is not consistent with the ground coordinate system, which makes it difficult to manage and schedule the communication beam of the low-orbit satellite. In addition, as a satellite-ground combined network, the satellite communication system also needs to consider the time synchronization problem between the beam planning, scheduling and control of the communication beam of the low-orbit satellite. Therefore, an effective technical solution is urgently needed to solve the above problems.

[0027] In this specification, three constellation beam management methods are provided. This specification also involves three constellation beam management devices, two satellite communication systems, a computing device, a computer-readable storage medium and a computer program product, which are described in detail one by one in the following embodiments.

[0028] See also Figure 1 , Figure 1 It is a scenario diagram of a constellation beam management method provided by an embodiment of this specification.

[0029] Figure 1 The system includes a communication satellite 102 and a user communication terminal 104, wherein the communication satellite 102 belongs to a satellite communication system, the position pointed to by the communication beam emitted by the communication satellite 102 is a virtual beam position, and there is a mapping relationship between the virtual beam position and the communication area on the ground.

[0030] Specifically, the satellite communication system can respond to the communication request sent by the user communication terminal 104, determine the target communication area where the user communication terminal is located, and determine the target wave position corresponding to the target communication area based on the mapping relationship between the communication area and the virtual wave position, generate a beam scheduling instruction according to the target wave position, and based on the beam scheduling instruction, control the target communication beam corresponding to the beam scheduling instruction to point to the target wave position, thereby achieving communication beam coverage for the user communication terminal 104 in the target communication area, processing the communication request sent by the user communication terminal 104, and establishing a communication connection between the user communication terminal 104 and the communication satellite 102.

[0031] See also Figure 2 , Figure 2 A flow chart of a first constellation beam management method provided according to an embodiment of the present specification is shown, which is applied to a satellite communication system and specifically includes the following steps.

[0032] Step 202: In response to a communication request sent by a user communication terminal, determine a target communication area corresponding to the user communication terminal.

[0033] Among them, the constellation beam can be understood as the communication beam of the communication satellite, and the user communication terminal can be understood as the terminal device used by the user for communication. The user communication terminal can be, for example, a mobile phone, a computer, etc., and the embodiments of this specification do not limit this. The communication request sent by the user communication terminal can be understood as a request sent by the user communication terminal to establish communication with the communication satellite. The communication request can be, for example, a network login request, a communication inclusion request, etc. The target communication area corresponding to the user communication terminal can be understood as the communication area of ​​the user communication terminal on the ground. In practical applications, the satellite communication system can be a low-orbit satellite system, and the communication satellite included in the low-orbit satellite system is a low-orbit satellite. Before the low-orbit satellite communication system is operated, it will be divided into multiple ground grids according to the ground area. The target communication area can be a ground grid among the multiple ground grids where the user communication terminal is located.

[0034] Based on this, the satellite communication system can respond to the request sent by the user communication terminal to establish communication with the communication satellite and determine the target communication area of ​​the user communication terminal on the ground.

[0035] For example, before the satellite communication system is operated, the ground area can be divided into multiple ground grids 1, 2, 3, 4, 5...N. The satellite communication system responds to the request sent by the user communication terminal to establish communication with the communication satellite and determines that the target communication area where the user communication terminal is located is ground grid 2.

[0036] A satellite communication system may include a ground communication terminal and a satellite communication terminal. In one embodiment of the present specification, the satellite communication system may use a ground scheduling mode for communication beam scheduling of a communication satellite. In the ground scheduling mode, the ground communication terminal may include a beam management platform, a beam scheduling unit, a gateway of a communication gateway station, and a measurement and control baseband, and the satellite communication terminal may include a measurement and control transponder, an on-board gateway, an on-board scheduling unit, and a beam controller. In the ground scheduling mode, the beam planning information (i.e., the mapping relationship between the communication area and the virtual wave position) is calculated in the beam management platform included in the ground communication terminal, and the beam scheduling instruction is generated in the beam scheduling unit included in the ground communication terminal, and the deployment cost is low.

[0037] In an actual application, in response to a communication request sent by a user communication terminal, determining a target communication area corresponding to the user communication terminal includes: The beam management platform determines a target communication area corresponding to the user communication terminal in response to a communication request sent by the user communication terminal; After determining the target communication area corresponding to the user communication terminal, the method further includes: The target communication area is sent to the beam scheduling unit.

[0038] Specifically, the beam management platform can determine the target communication area corresponding to the user communication terminal in response to the communication request sent by the user communication terminal, and send the target communication area to the beam scheduling unit.

[0039] In summary, the target communication area is determined by the beam management platform and sent to the beam scheduling unit, so that the beam scheduling unit can subsequently determine the target beam position corresponding to the target communication area.

[0040] In specific implementation, the communication request sent by the user communication terminal may carry the geographic location information of the user communication terminal. The beam management platform may determine, based on the geographic location information, multiple candidate communication areas associated with the geographic location information, and determine the location information of the regional center point of each candidate communication area. Based on the geographic location information and the location information of the regional center point of each candidate communication area, the distance between the location of the user communication terminal and the location of the regional center point of each candidate communication area is calculated, and the candidate communication area whose distance is less than a preset distance threshold is determined as the target communication area.

[0041] In addition, the distances between the location of the user communication terminal and the locations of the center points of the candidate communication areas may be compared, and the candidate communication area with the shortest distance may be determined as the target communication area according to the comparison result.

[0042] The multiple candidate communication areas associated with the geographic location information can be understood as the communication areas included in the preset distance range of the geographic location information. For example, the coordinates of the geographic location information are (x, y), and the preset distance range can be 5 meters. Then, the multiple candidate communication areas associated with the geographic location information are the communication areas included in the range of (x+5, x-5) and (y+5, y-5).

[0043] Continuing with the above example, the beam management platform determines the geographic location information of the user communication terminal in response to the communication request sent by the user communication terminal, and based on the geographic location information, determines ground grids 1, 2, and 5 as candidate communication areas among multiple ground grids 1, 2, 3, 4, 5...N. Taking ground grid 1 as an example, the location information of the center point of ground grid 1 is determined, and based on the geographic location information and the location information, the distance L1 between the location of the user communication terminal and the center point of ground grid 1 is calculated. Similarly, the distance L2 between the location of the user communication terminal and the center point of ground grid 2 is calculated, and the distance L3 between the location of the user communication terminal and the center point of ground grid 5 is calculated. When L2 is determined to be the smallest, ground grid 2 is determined as the target communication area corresponding to the user communication terminal.

[0044] In summary, by calculating the distance between the candidate communication area and the location of the user communication terminal, the target communication area where the user communication terminal is located is determined, which facilitates subsequent scheduling and control of the communication beam to point to the target communication area, thereby achieving coverage of the user communication terminal.

[0045] Step 204: Determine the target beam position corresponding to the target communication area according to a comparison table between communication areas and virtual beam positions, wherein the comparison table is used to record a mapping relationship between the communication area and the virtual beam position, and the virtual beam position is a reference position to which a communication beam emitted by a communication satellite points.

[0046] Among them, the virtual beam position can be understood as the reference position to which the communication beam emitted by the communication satellite may point. Each communication beam can correspond to multiple virtual beam positions, for example, communication beam 1 can point to virtual beam position 1 at angle A, and communication beam 1 can point to virtual beam position 2 at angle B, etc. The mapping relationship between the communication area and the virtual beam position can be understood as the corresponding relationship between the virtual beam position and the communication area. The communication area and the virtual beam position correspond to each other, that is, the communication beam pointing to the virtual beam position can cover the communication area corresponding to the virtual beam position. For example, virtual beam position 1 can correspond to communication area 1 and communication area 2. Then, when the communication beam that can point to the virtual beam position 1 points to the virtual beam position 1, it can cover the communication area 1 and communication area 2 corresponding to the virtual beam position 1. Then, the user communication terminals in communication area 1 and communication area 2 can achieve communication. The target beam position can be understood as the virtual beam position corresponding to the target communication area.

[0047] Based on this, the target wave position corresponding to the target communication area can be determined according to a comparison table recording the mapping relationship between the communication area and the virtual wave position.

[0048] In an actual application, before determining the target wave position corresponding to the target communication area according to the comparison table between the communication area and the virtual wave position, the method further includes: The beam management platform calculates the virtual beam position of the communication satellite according to a preset planning period, and determines a mapping relationship between the communication area and the virtual beam position; The mapping relationship between the communication area and the virtual beam position is stored in the comparison table in the beam management platform.

[0049] Among them, the beam management platform can be used to implement non-real-time beam planning. Specifically, the beam management platform can calculate the correspondence between the communication area (i.e., the ground grid), the virtual wave position and the communication beam, and can maintain the coordinate system of the ground communication area (i.e., the ground grid coordinate system). The preset planning period can be understood as a time parameter for beam management. The preset planning period is an injection period. During the operation of the communication satellite, the virtual wave position to which the communication beam emitted by the communication satellite may point may also change. Therefore, the beam management platform can update the mapping relationship between the virtual wave position of the communication satellite and the communication area every injection period. The preset planning period can be, for example, 24 hours.

[0050] Based on this, the beam management platform can calculate the virtual beam position of the communication satellite every preset planning period, determine the mapping relationship between the communication area and the virtual beam position, and store the mapping relationship in a comparison table.

[0051] In practical applications, see Figure 3 , Figure 3 A schematic diagram of the division of beam management levels in a constellation beam management method provided according to an embodiment of the present specification is shown. The beam management process can be divided into five levels: ground grid, virtual wave position, communication beam, service cell and routing tracking area. The ground grid (i.e., the above-mentioned communication area) can be understood as a ground area that is planned on the ground according to the orbital information of the communication satellite and the beam-related parameters emitted by the phased array antenna, bound to the longitude and latitude coordinates, and fixed on the ground, and can be used as an anchor point for beam management. In practical applications, the ground grid can be a plurality of hexagons of equal shapes planned on the earth, which are used for position synchronization with the user communication terminal and can also guide the communication beam pointing of the communication satellite. The user communication terminal can determine its own position through the grid coordinates of the ground grid on the ground, and synchronize its position with the satellite communication system. The virtual wave position can be understood as the full set of possible pointing directions of the communication beam emitted by the communication satellite, which is generated according to the beam gaze period of the communication satellite or the jump period of the jump beam emitted by the communication satellite, the orbital height of the communication satellite and the parameters of the phased array antenna. The beam pointing of the communication beam forms a set of beam positions on the ground. These beam positions are virtual and are not real beam pointings. The communication beam can be a single-satellite beam, which refers to the beam resources that each communication satellite can schedule. Each communication beam can correspond to multiple virtual beam positions, which can actually be the possible directions of the communication beam. The service cell can be understood as a cell used to serve users. In practical applications, it can be similar to a cellular cell in a terrestrial network. Each service cell can correspond to one or more beams. The routing tracking area (ie, TA area) is allocated according to the core network and the gateway station. A single gateway station or multiple gateway stations can be allocated as a routing tracking area. Figure 3As shown, in a certain route tracking area, there are service cells Cell1 and service cell Cell2. Service cell Cell1 corresponds to communication beams Beam1 and Beam2, service cell Cell2 corresponds to communication beams Beam9 and Beam10, the virtual beam positions corresponding to communication beam Beam1 are Beam Position1 and Beam Position2, the virtual beam positions corresponding to communication beam Beam9 are Beam Position3, the virtual beam positions corresponding to communication beam Beam10 are Beam Position4 and BeamPosition5, the ground grids corresponding to the virtual beam position Beam Position1 are Grid1 and Grid2, the ground grid corresponding to the virtual beam position BeamPosition3 is Grid3, and the ground grids corresponding to the virtual beam position Beam Position4 are Grid4, Grid5 and Grid6.

[0052] In summary, by separating the virtual wave position and the ground grid and calculating the mapping relationship between the virtual wave position and the ground grid, a coordinate system for positioning the user communication terminal can be formed on the ground by grids of equal size, and the wave position deformation caused by the change of the beam scanning angle of the antenna of the recursive communication satellite can be adapted to better utilize the beam resources. The correspondence between the virtual wave position and the ground grid is achieved through the mapping relationship, which solves the problem of mismatch between the ground coordinate system of the communication satellite and the real wave position shape, and ensures that beam management and scheduling are easy to implement.

[0053] In practical applications, the preset planning period includes multiple preset time intervals; The beam management platform calculates the virtual beam position of the communication satellite according to a preset planning period, and determines a mapping relationship between the communication area and the virtual beam position, including: The beam management platform calculates the virtual beam position of the communication satellite in each preset time interval according to the preset planning period, and determines the mapping relationship between the communication area and the virtual beam position in each preset time interval.

[0054] The preset time interval is the period for reconstructing the virtual wave position of the communication satellite. The preset planning period may include multiple preset time intervals, and the preset planning period also includes the activation scheduling time of the preset time interval.

[0055] Based on this, the beam management platform can calculate the virtual beam position of the communication satellite in each preset time interval according to each preset time interval included in the preset planning cycle, and determine the mapping relationship between the communication area and the virtual beam position in each preset time interval.

[0056] In summary, by setting the preset planning cycle and the preset time interval, satellite-ground synchronization can be achieved, and the reconstruction of the virtual wave position caused by the flight of the communication satellite, which leads to the failure to update the mapping relationship between the virtual wave position and the communication area in time, can be avoided, thereby ensuring the timeliness of the update of the mapping relationship between the virtual wave position and the communication area.

[0057] In practical applications, the ground communication terminal further includes a beam scheduling unit; After storing the mapping relationship between the communication area and the virtual beam position in the comparison table in the beam management platform, the method further includes: The comparison table is sent to the beam scheduling unit.

[0058] Specifically, after the mapping relationship between the communication area and the virtual beam position is stored in a comparison table in the beam management platform, the comparison table can be sent to the beam scheduling unit.

[0059] In actual applications, the comparison table updated in each preset planning period can be sent to the beam scheduling unit according to the preset planning period.

[0060] In summary, by sending the comparison table to the beam scheduling unit, the beam scheduling unit can subsequently determine the target beam position corresponding to the target communication area according to the comparison table, so as to subsequently control the communication beam to point to the target beam position.

[0061] Step 206: Generate a beam scheduling instruction according to the target beam position.

[0062] Among them, the beam scheduling instruction can be understood as a scheduling instruction for the target communication beam that can point to the target beam position.

[0063] In a specific implementation, determining the target wave position corresponding to the target communication area according to the comparison table between the communication area and the virtual wave position includes: The beam scheduling unit determines the target beam position corresponding to the target communication area according to the comparison table between the communication area and the virtual beam position.

[0064] Generating a beam scheduling instruction according to the target beam position includes: The beam scheduling unit generates the beam scheduling instruction according to the target beam position.

[0065] Specifically, the beam scheduling unit can receive the comparison table and target communication area sent by the beam management platform, and determine the target wave position corresponding to the target communication area based on the comparison table between the communication area and the virtual wave position, and generate a scheduling instruction for the target communication beam that can point to the target wave position based on the target wave position.

[0066] In summary, the generation of the beam scheduling instruction by the beam scheduling unit facilitates the subsequent scheduling and control of the corresponding target communication beam according to the beam scheduling instruction.

[0067] Step 208: Based on the beam scheduling instruction, control the target communication beam corresponding to the beam scheduling instruction to point to the target beam position to process the communication request.

[0068] In a specific implementation, after the beam scheduling unit generates the beam scheduling instruction according to the target beam position, the method further includes: The beam scheduling unit sends the beam scheduling instruction to the satellite communication terminal; Based on the beam scheduling instruction, controlling the target communication beam corresponding to the beam scheduling instruction to point to the target beam position to process the communication request includes: The satellite communication terminal, based on the beam scheduling instruction, controls the target communication beam corresponding to the beam scheduling instruction to point to the target beam position to process the communication request.

[0069] Specifically, after the beam scheduling unit generates the beam scheduling instruction, it can send the beam scheduling instruction to the satellite communication terminal. The satellite communication terminal can control the target communication beam corresponding to the beam scheduling instruction to point to the target beam position based on the beam scheduling instruction to process the communication request and realize the communication connection between the user communication terminal and the satellite communication terminal.

[0070] In summary, the communication request can be processed through the interaction between the beam scheduling unit and the satellite communication terminal.

[0071] In practical applications, the satellite communication terminal includes an on-board scheduling unit and a wave controller; The satellite communication terminal controls the target communication beam corresponding to the beam scheduling instruction to point to the target beam position based on the beam scheduling instruction to process the communication request, including: The on-board scheduling unit generates a beam control instruction for the target communication beam based on the beam scheduling instruction, and sends the beam control instruction to the beam controller; The beam controller controls the target communication beam to point to the target beam position based on the beam control instruction to process the communication request.

[0072] Among them, the beam controller can be understood as a unit on the communication satellite used to control the phased array antenna. By sending beam control instructions to the beam controller, the beam controller can control the target communication beam to point to the target beam position according to the beam control instructions, thereby realizing the communication connection between the communication satellite and the user communication terminal.

[0073] Based on this, the onboard scheduling unit can generate a beam control instruction for the target communication beam based on the beam scheduling instruction, and send the beam control instruction to the beam controller. The beam controller controls the target communication beam to point to the target beam position based on the beam control instruction to process the communication request issued by the user communication terminal.

[0074] In practical applications, the beam management platform of the ground communication terminal can inject the planning information (i.e., the comparison table) into the beam scheduling unit every preset planning period. The beam scheduling unit can determine the target wave position according to the comparison table and the target communication area, and generate a beam scheduling instruction to perform periodic pre-scheduling and real-time scheduling. The generated beam scheduling instruction is sent to the satellite scheduling unit. The satellite scheduling unit can generate a beam control instruction based on the beam scheduling instruction, and send the beam control instruction to the wave controller of the phased array antenna. The wave controller controls the target communication beam to point to the target wave position based on the beam control instruction to adjust the communication beam direction. It can be understood that the planning of the planning information by the beam management platform is non-real-time. The corresponding relationship between the ground grid, virtual wave position and communication beam can be calculated, and the ground grid coordinate system can be maintained. The scheduling of the communication beam by the beam scheduling unit is periodic real-time control, and the target communication beam needs to be scheduled to cover the target wave position. The control of the target communication beam has high real-time performance, and the communication beam of the phased array is controlled by the wave controller to point to the target wave position.

[0075] In summary, through the on-board scheduling unit and beam controller, real-time control of the target communication beam is achieved, thereby realizing the direction adjustment of the target communication beam, ensuring that the target communication beam can cover the target wave position, and facilitating the establishment of the communication connection between the user communication terminal and the satellite communication terminal.

[0076] In another embodiment of the present specification, the satellite communication system may use an on-board scheduling mode for communication beam scheduling of a communication satellite.

The beam scheduling instructions are generated in the beam scheduling unit included in the satellite communication terminal, with fast calculation speed and high efficiency.

[0077] Specifically, the satellite communication terminal includes a beam scheduling unit; After storing the mapping relationship between the communication area and the virtual beam position in the comparison table in the beam management platform, the method further includes: The comparison table is sent to the beam scheduling unit.

[0078] Specifically, the beam management platform may send the comparison table to the beam scheduling unit of the satellite communication terminal, so that the beam scheduling unit can subsequently determine the target beam position according to the comparison table.

[0079] Then, in response to a communication request sent by a user communication terminal, determining a target communication area corresponding to the user communication terminal includes: The beam management platform determines a target communication area corresponding to the user communication terminal in response to a communication request sent by the user communication terminal; After determining the target communication area corresponding to the user communication terminal, the method further includes: The target communication area is sent to the beam scheduling unit.

[0080] Specifically, after determining the target communication area corresponding to the user communication terminal, the beam management platform can also send the target communication area to the beam scheduling unit to facilitate the beam scheduling unit to subsequently determine the target beam position corresponding to the target communication area.

[0081] Accordingly, according to the comparison table between the communication area and the virtual wave position, determining the target wave position corresponding to the target communication area includes: The beam scheduling unit determines the target beam position corresponding to the target communication area according to the comparison table between the communication area and the virtual beam position.

[0082] Generating a beam scheduling instruction according to the target beam position includes: The beam scheduling unit generates the beam scheduling instruction according to the target beam position.

[0083] Specifically, the beam scheduling unit can determine the target beam position corresponding to the target communication area according to the comparison table between the communication area and the virtual beam position, and generate a beam scheduling instruction according to the target beam position to achieve subsequent control of the target communication beam.

[0084] Furthermore, the satellite communication terminal further comprises a wave controller; Based on the beam scheduling instruction, controlling the target communication beam corresponding to the beam scheduling instruction to point to the target beam position to process the communication request includes: The beam scheduling unit generates a beam control instruction for the target communication beam based on the beam scheduling instruction, and sends the beam control instruction to the beam controller; The beam controller controls the target communication beam to point to the target beam position based on the beam control instruction to process the communication request.

[0085] Specifically, after the beam scheduling unit generates a beam control instruction for the target communication beam based on the beam scheduling instruction, the beam control instruction can be sent to the beam controller. The beam controller controls the target communication beam to point to the target beam position based on the beam control instruction to process the communication request.

[0086] It can be understood that the processing process in the on-board scheduling mode is similar to the processing process in the ground scheduling mode, the difference being that the locations where the beam scheduling units are deployed are different.

[0087] In a specific implementation, sending the comparison table to the beam scheduling unit includes: According to the preset planning period, sending the comparison table corresponding to the preset time interval to the beam scheduling unit; The preset time interval is a period for reconstructing the virtual wave position of the communication satellite.

[0088] Specifically, similar to the above, the beam management platform can send the comparison table corresponding to each preset time interval to the beam scheduling unit according to the preset planning period.

[0089] Furthermore, each of the preset time intervals includes a plurality of scheduling cycles; The beam scheduling unit generates a beam control instruction for the target communication beam based on the beam scheduling instruction, and sends the beam control instruction to the beam controller, including: The beam scheduling unit generates a beam control instruction for the target communication beam based on the beam scheduling instruction according to the scheduling period and the pre-scheduling period, and sends the beam control instruction to the beam controller; The pre-scheduling period is a time interval for adjusting a time parameter for sending the beam scheduling instruction in advance.

[0090] In practical applications, the time parameters used for beam management include the injection period (i.e. the preset planning period) , the stepping cycle (i.e., preset time interval) of virtual wave position reconstruction caused by the flight of the communication satellite , Pre-scheduling period , pre-scheduled variables and scheduling cycle , see Figure 4 , Figure 4 The diagram shows the relative relationship of the time parameters used for beam management in a constellation beam management method provided by an embodiment of the specification. Specifically, the beam management platform notifies the planning information once every preset planning period. The planning information includes N preset time intervals and the absolute activation time of the preset time interval. Each preset time interval includes multiple scheduling periods. The communication base station can generate beam scheduling instructions according to the scheduling period and synchronize the absolute time with the beam scheduling unit on the satellite. The pre-scheduling period is to adjust the time parameters for sending scheduling instructions in advance. time interval. It can be the same time parameter or different time parameters to offset the changing feeder link transmission delay. Specifically, the scheduling period can be understood as the time interval for actually executing beam control (i.e., beam scheduling), and the pre-scheduling period can be understood as a set of scheduling periods, which can be understood as the time interval for transmitting the beam scheduling instruction to the control execution unit in advance. The pre-scheduling variable (i.e., time parameter) can be understood as the advance amount for sending the beam scheduling instruction.

[0091] In summary, by setting the time parameters, the time synchronization between the satellite and the ground can be achieved.
