Technical Field

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

[0002] With the continuous development of satellite-terminal direct communication technology, it is now possible to provide direct communication services to multiple terminals in a specific area simultaneously through a single satellite. In this process, the satellite uses signaling beams to poll the terminals in the specific area that need to establish direct communication with the target satellite, and then uses service beams to complete the communication data transmission between the satellite and multiple terminals.

[0003] However, in the traditional direct communication transmission process between a single satellite and multiple terminals, since the multiple terminals do not have fixed-location communication data transmission or communication data transmission for the entire period of time, the rationality of the use of the signaling beam and / or service beam resources provided by the satellite for that specific area is reduced due to the movement of the terminals or the incomplete communication for the entire period of time.

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 method for direct communication between a satellite and multiple terminals, which can be executed by an electronic device. The electronic device can be a server, which can be an independent physical server, a server cluster composed of multiple physical servers, or a distributed device, or a cloud server that provides cloud computing services. The server can be installed on a ground terminal or on a high-orbit satellite.

[0036] Reference Figure 1A direct communication method between a satellite and multiple terminals includes steps S101, S102, S103, and S104, wherein...

[0037] S101, determine the distribution information of the terminals to be served corresponding to the target communication area, and based on the distribution information of the terminals to be served and the target communication area, determine the multiple signaling beam paging areas corresponding to the target satellite.

[0038] In some embodiments, the terminal distribution information to be served is information reflecting the distribution of all terminals that need to conduct direct satellite communication within the target communication area; the signaling beam paging area is a portion of the target communication area that needs to be polled using the signaling beam.

[0039] There are numerous terminals in the target communication area capable of providing direct communication services to the target satellite. However, these terminals do not maintain direct communication with the target satellite at all times or continuously transmit data. Therefore, the distribution of terminals requiring direct communication with the target satellite will vary each time the target satellite reaches a point where it can provide direct communication services to terminals within the target communication area. This varying terminal distribution directly affects the allocation of signaling and service beam resources by the target satellite to the target communication area. Consequently, before establishing direct communication connections between the target satellite and multiple terminals within the target communication area, it is necessary to determine the actual terminal situation within the target communication area, i.e., the distribution of terminals requiring direct communication connections with the target satellite.

[0040] The electronic device uses the initial terminal information acquired within a preset historical time period in the target communication area to determine the candidate terminal information within the target communication area. Based on the candidate terminal information, it determines the location information of the terminals within the target communication area. Using the location information of the terminals, it determines the distribution information of the terminals to be served corresponding to the target communication area. Then, the electronic device uses the distribution information of the terminals to be served to divide the target communication area into regions, determine multiple sub-target communication areas that are reasonable for paging using signaling beams at the current time, and define the multiple sub-target communication areas as signaling beam paging areas.

[0041] S102, obtain paging information corresponding to multiple signaling beam paging areas respectively, and determine the terminal information to be served corresponding to multiple signaling beam paging areas based on the paging information.

[0042] In some embodiments, paging information is the paging information sent by the terminal to the target satellite during the polling process of the target satellite using the signaling beam to its corresponding signaling beam paging area. The paging information may include synchronization information, broadcast information, and random access information, etc.; the terminal information to be served is the communication information that the terminal needs to upload when it needs to perform direct communication service.

[0043] After identifying multiple signaling beam paging areas within the target communication area, the electronic device generates a signaling beam paging command and sends it to the target satellite. The target satellite responds to the command by polling its respective signaling beam paging area using multiple signaling beams. When a terminal within a signaling beam paging area needs direct communication, the terminal sends paging information to the target satellite, which then forwards the received information to the electronic device. The electronic device then analyzes the paging information to determine the preliminary communication content corresponding to each terminal. Based on this content, it identifies the terminal information for each terminal. Finally, the electronic device integrates the terminal information from multiple terminals located within the same signaling beam paging area to obtain the terminal information to be served for each signaling beam paging area.

[0044] S103, based on the information of the terminal to be served, determines the service beam resource call volume corresponding to each of the multiple signaling beam paging areas.

[0045] In some embodiments, the service beam resource call volume is information reflecting the call status of all service beam resources required for direct-connect communication service terminals in the signaling beam paging area.

[0046] Based on the information of the terminal to be served, the electronic device determines multiple communication types corresponding to each signaling beam paging area, integrates multiple initial communication data belonging to the same communication type, and processes the integrated initial communication data using the communication data processing rules corresponding to the communication type to obtain the communication data to be sent to the target satellite. Then, the electronic device determines the single communication resource consumption corresponding to the communication data, and determines the service beam resource call amount corresponding to each signaling beam paging area based on the single communication resource consumption.

[0047] S104, based on the amount of service beam resource allocation, controls the target satellite to use service beams to provide direct communication services to the terminals waiting to be served in the paging area of ​​multiple signaling beams.

[0048] In some embodiments, the electronic device sends the service beam resource request quantity to the target satellite. The target satellite responds to the service beam resource request quantity and determines the service beam resource quantity corresponding to each signaling beam paging area. Then, based on the service beam resource quantity, the electronic device controls its own service beam to provide direct communication services to terminals in multiple signaling beam paging areas. This rationally divides the target communication area and determines the signaling beam paging area corresponding to each signaling beam, thereby further improving the rationality of the use of the target satellite's signaling beam and increasing the efficiency of signaling beam paging. Finally, by determining the communication data of the terminal corresponding to each signaling beam paging area, the service beam resource request quantity adapted to each signaling beam paging area is determined, thereby improving the rationality of the target satellite's service beam resource request.

[0049] In step S101, determining the distribution information of the terminals to be served corresponding to the target communication area includes: obtaining initial terminal information corresponding to a preset number of adjacent preset historical time periods corresponding to the target communication area; determining multiple first candidate terminal information based on multiple initial terminal information, and obtaining multiple second candidate terminal information corresponding to a preset historical time period closest to the current time corresponding to the target communication area; and determining the distribution information of the terminals to be served based on multiple first candidate terminal information and multiple second candidate terminal information.

[0050] In some embodiments, the initial terminal information is information reflecting the communication data transmission status of direct communication services between all terminals within the target communication area and the target satellite within a preset historical time period; the first candidate terminal information is information reflecting the communication data transmission status between a certain terminal and the target satellite, wherein the certain terminal is a terminal that has established direct communication with the target satellite in adjacent preset number of preset historical time periods; the second candidate terminal information is information reflecting the communication data transmission status between any terminal and the target satellite, wherein any terminal is a terminal that has proposed direct communication services with the target satellite only in the preset historical time period closest to the current time.

[0051] The electronic device obtains initial terminal information within a predetermined number of predetermined historical time periods within the target communication area from the communication data storage device. Then, the electronic device analyzes the initial terminal information to identify the terminal information of terminals that have established direct communication services with the target satellite within each historical time period, and designates this terminal information as the first candidate terminal information. Simultaneously, the electronic device obtains all terminal information within the predetermined historical time period closest to the current time and compares this terminal information with the initial terminal information to filter out multiple second candidate terminal information. Subsequently, the electronic device determines the first location information corresponding to each of the multiple first candidate terminal information and the second location information corresponding to each of the multiple second candidate terminal information, and integrates the multiple first and second location information to determine the distribution information of the terminals to be served within the target communication area.

[0052] In some embodiments, the distribution information of the terminals to be served includes the distribution information of newly added terminals and the distribution information of resident terminals. Then, in step S101, based on the distribution information of the terminals to be served and the target communication area, multiple signaling beam paging areas corresponding to the target satellite are determined, including: based on the distribution information of resident terminals, the target communication area is initially divided to obtain multiple sub-target communication areas, and the number of resident terminals corresponding to each of the multiple sub-target communication areas is obtained; based on the distribution information of newly added terminals and the number of resident terminals, the size of the range of the multiple sub-target communication areas is adjusted to obtain multiple signaling beam paging areas.

[0053] In some embodiments, the distribution information of the temporary terminal is information about the distribution of the second location information corresponding to the information of the multiple second candidate terminals; the distribution information of the permanent terminal is information about the distribution of the first location information corresponding to the information of the multiple first candidate terminals.

[0054] The electronic device invokes a preset area division principle and, based on the distribution information of resident terminals, initially divides the target communication area to obtain multiple sub-target communication areas. The preset area division principle is to ensure that the number of resident terminals contained in each sub-target communication area is within a preset range. Subsequently, the electronic device obtains the number of resident terminals corresponding to each sub-target communication area, and, based on the distribution information of imminent additional terminals and the number of resident terminals, further adjusts the range of the multiple sub-target communication areas to obtain multiple signaling beam paging areas.

[0055] In some embodiments, based on the distribution information of imminent additional terminals and the number of resident terminals, the size of multiple sub-target communication areas is adjusted to obtain multiple signaling beam paging areas, including: determining the number of imminent additional terminals corresponding to each of the multiple sub-target communication areas based on the distribution information of imminent additional terminals; if the difference in the number of imminent additional terminals corresponding to any two adjacent sub-target communication areas exceeds a first preset difference, adjusting the two sub-target communication areas so that the difference in the number of imminent additional terminals corresponding to the two sub-target communication areas is less than a second preset difference, and determining the two sub-target communication areas after area adjustment as signaling beam paging areas.

[0056] In some embodiments, the electronic device determines the number of temporary terminals located in each sub-target communication area based on the distribution information of temporary terminals. Then, the electronic device calculates the difference between the number of temporary terminals in two adjacent sub-target communication areas to obtain the quantity difference. Subsequently, the electronic device compares these quantity differences with a first preset quantity difference. If the quantity difference between the number of temporary terminals in any two adjacent sub-target communication areas exceeds the first preset quantity difference, it indicates that the difference in the number of new terminals between the two sub-target communication areas is too large. Since the new terminals are temporary direct-connection communication terminals, there is a possibility that the temporary terminals in the sub-target communication areas with a large number of new terminals may lose contact with the target satellite in a short period, resulting in excessive waste of service beam resources corresponding to the sub-target communication area. Therefore, the electronic device adjusts the two sub-target communication areas to make the quantity difference between the number of temporary terminals in the two sub-target communication areas less than a second preset quantity difference, and determines the two sub-target communication areas after the adjustment as signaling beam paging areas.

[0057] In some embodiments, based on the distribution information of imminent additional terminals and the number of resident terminals, the size of multiple sub-target communication areas is adjusted to obtain multiple signaling beam paging areas. This includes: generating an area reduction instruction when the number of resident terminals in any sub-target communication area exceeds a preset number of terminals, wherein the area reduction instruction includes area reduction control information and area reduction rules; controlling any sub-target communication area to reduce its size based on the area reduction control information, and determining the final number of resident terminals corresponding to any sub-target communication area based on the area reduction rules; stopping the reduction control of any sub-target communication area when the number of resident terminals contained within any sub-target communication area is less than or equal to the final number of resident terminals, and determining the sub-target communication area at the time of stopping the area reduction as a signaling beam paging area.

[0058] In some embodiments, the electronic device compares the number of resident terminals corresponding to each of the multiple sub-target communication areas with a preset number of terminals. If it is determined that the number of resident terminals in any of the multiple sub-target communication areas exceeds the preset number of terminals, it indicates that there are a large number of terminals in any sub-target communication area that need to establish direct communication with the target satellite. This indicates that the resource requirements of the signaling beam and / or service beam of the sub-target communication area are high, and the efficiency of the signaling beam polling the sub-target communication area and / or the service beam transmitting the communication data of the sub-target communication area is low.

[0059] Then, it can be considered to shrink any sub-target communication area. That is, the electronic device generates an area shrinking instruction and starts to execute the area shrinking process of any sub-target communication area based on the area shrinking instruction. The number of resident terminals contained in any sub-target communication area during the shrinking process is limited by the area shrinking rules in the area shrinking instruction, that is, the final number of resident terminals. Subsequently, when the electronic device determines that the number of resident terminals contained in any sub-target communication area is less than or equal to the final number of resident terminals, the area shrinking process of any sub-target communication area is stopped, and the sub-target communication area after the area shrinking is stopped is determined as the signaling beam paging area.

[0060] Step S103, based on the information of the terminal to be served, determines the service beam resource call volume corresponding to each of the multiple signaling beam paging areas, including: based on the information of the terminal to be served, determining the multiple communication types corresponding to each of the multiple signaling beam paging areas and the initial communication data corresponding to each of the multiple communication types; determining the communication data processing rules corresponding to each of the multiple communication types, and based on the communication data processing rules and the initial communication data, determining the single communication resource consumption corresponding to each of the multiple communication types; and based on the multiple single communication resource consumption, determining the service beam resource call volume corresponding to each of the multiple signaling beam paging areas.

[0061] In some embodiments, the electronic device analyzes the information of the terminal to be served, determines the multiple communication types corresponding to each signaling beam paging area, and integrates the multiple communication data contained in the terminal to be served information belonging to the same communication type to obtain the initial communication data of that communication type; subsequently, the electronic device calls the preset communication type-data processing rule database and determines the communication data processing rules corresponding to each communication type from the database.

[0062] Subsequently, the electronic device processes the initial communication data using data processing rules to obtain processed initial communication data and acquire the data volume of the processed initial communication data. Based on this data volume, the electronic device determines the single communication resource consumption corresponding to its corresponding communication data type. Then, the electronic device integrates the single resource consumption corresponding to multiple communication types belonging to the same signaling beam paging area to obtain the service beam resource call volume corresponding to multiple signaling beam paging areas. Thus, by using the communication data processing rules corresponding to the communication type to process the initial communication data to be sent to the target satellite locally, the data transmission volume of the target satellite uplink is reduced, and the probability of uplink congestion of the target satellite is reduced.

[0063] In some embodiments, after controlling the target satellite to use service beams to provide direct communication services to the terminals to be served in multiple signaling beam paging areas based on the service beam resource allocation in step S104, a direct communication method between a satellite and multiple terminals further includes: obtaining the service beam resource usage corresponding to each of the multiple signaling beam paging areas within a preset unit time period; comparing the multiple service beam resource usage with their corresponding service beam resource allocation to obtain multiple beam resource differences; if any of the multiple beam resource differences exceeds a preset beam resource difference, generating a reduction beam resource allocation instruction corresponding to any beam resource difference, and reducing the service beam resource allocation in the signaling beam paging area corresponding to any beam resource difference based on the reduction beam resource allocation instruction.

[0064] In some embodiments, over time, it is possible that service beam resources in a certain area within the target communication area may be wasted. Therefore, during direct communication between the target satellite and terminals within the same communication area, the usage of the target satellite's service beam resources can be monitored in real time. Specifically, the electronic device acquires the service beam resource usage corresponding to multiple signaling beam paging areas within a preset unit time period, compares the service beam resource usage with its corresponding service beam resource call volume, and calculates the difference to obtain a beam resource difference. Subsequently, the electronic device compares the beam resource difference with a preset beam resource difference. If any beam resource difference exceeds the preset difference, it indicates excessive waste of service beam resources in the signaling beam polling area corresponding to that difference. The electronic device then generates a reduction beam resource allocation instruction corresponding to that difference and sends it to the target satellite to control the target satellite to reduce the service beam resource call volume in the signaling beam paging area corresponding to that difference, thereby improving the rationality of the target satellite's service beam resource utilization.
