Detailed Implementation

[0025] The present application will be further described in conjunction with the accompanying drawings and embodiments. The described embodiments are only some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art should fall within the protection scope of the embodiments of the present application.

[0026] See Figure 1 This application provides an embodiment of a satellite resource allocation method, which includes: Step 1: The satellite receives the first information; the first information is the first resource scheduling information sent by the ground data center; the first resource scheduling information includes the initial state flag, the first number of concurrent user terminals, and the user terminal release group; the initial state flag is used to indicate whether the satellite is in the initial state or the normal state.

[0027] Optionally, a terrestrial data center refers to a server group deployed on the ground, possessing significant computing power, responsible for integrating resource scheduling information based on user terminal distribution maps or user statistics. Optionally, the terrestrial data center can upload initial information to satellites via ground stations. A ground station refers to a ground-based station responsible for uploading messages and receiving messages transmitted from the satellite. A satellite refers to a low-Earth orbit satellite responsible for allocating resources based on the resource scheduling information uploaded by the ground station, receiving random access requests from user terminals, allocating spectrum and time resources to requesting user terminals according to resource configuration results, and recording the number of random access requests received from user terminals per minute.

[0028] Optionally, see Figure 2 Before step 1, the following is also included: At the initial moment, the ground data center determines whether it has obtained a user terminal distribution map; the user terminal distribution map can be obtained by statistically analyzing the sales of user terminals, and the information of the user terminal distribution map includes the latitude and longitude information of the user terminals; if a user terminal distribution map exists, proceed to step 100, otherwise proceed to step 101. Step 100: In the initial satellite state, the ground data center integrates resource scheduling information every 15 minutes. Based on the latitude and longitude information of the user terminals, satellite ephemeris, and satellite orbit design parameters, the visibility between each satellite and the user terminal for the next 15 minutes is calculated (the method for obtaining visibility can be obtained through CN118944735A). The initial concurrent user terminal count (first concurrent user terminal count) n is calculated using the following formula:

[0029] Wherein, the initial number of concurrent user terminals n is an integer; the initial user terminal concurrency factor takes the value [0,1], and is selected according to the actual situation. For example, if an IoT terminal reports data every 30 minutes, the initial user terminal concurrency factor of the IoT terminal can be 50%. There is no restriction on the value of the initial user terminal concurrency factor. Optionally, if visibility is true, the number of visible users is counted once, and the number of visible users for the next 15 minutes is finally obtained.

[0030] In the above embodiment, the initial state flag in the resource scheduling information is 1, and the initial number of concurrent user terminals is n.

[0031] Step 101: Integrate resource scheduling information in the ground data center. The initial status flag in the resource scheduling information is set to 1; the initial concurrent user terminal count is 0.

[0032] The satellite in this application only needs to configure and allocate resources based on the resource scheduling information uploaded by the ground station. A large amount of calculation is completed by the ground data center, which reduces the computational load on the satellite.

[0033] Step 2: The satellite determines the resource allocation result based on the first information received; the resource allocation result is used to indicate that the resources should be divided equally into multiple parts.

[0034] In one embodiment of this application, the satellite sends a resource release request to the user terminal corresponding to the user terminal release group and marks the status of the resource released by the user terminal as idle. The user terminal release group includes the network identifier of the user terminal that needs to release resources and the resource release time. The satellite determines the number of spectrum segments in the idle state according to the initial state flag bit. The satellite divides the spectrum in the idle state into resources according to the number of spectrum segments in the idle state.

[0035] In one embodiment of this application, the satellite determines the number of spectrum segments to be evenly distributed in the idle state based on the initial state flag bit, including: if the value of the initial state flag bit is a first value, the satellite determines the number of spectrum segments to be evenly distributed in the idle state based on the number of concurrent users of the first user terminal; the first value is used to indicate that the satellite is in the initial state; the initial state refers to the state of the satellite from the start of operation to the completion of one orbit.

[0036] In one embodiment of this application, the satellite determines the number of spectrum segments to be evenly divided in the idle state based on the number of concurrent users of the first user terminal, including: if the number of concurrent users of the first user terminal is equal to a first preset value, the satellite divides the spectrum segments in the idle state into a first preset number; otherwise, the satellite divides the spectrum segments in the idle state into a second preset number; the second preset number is equal to the number of concurrent users of the first user terminal.

[0037] Optionally, the spectrum release process is performed directly by the satellite, without requiring the user terminal to return a response.

[0038] In one possible implementation, the satellite first determines the initial state flag. If the initial state flag is 1, and the initial concurrent user terminal count n is 0, the idle spectrum resources are divided equally into 10,000 parts (the number 10,000 can be adjusted according to the actual situation; the reason for using a constant is that no other algorithms need to be deployed on the satellite, thus reducing the computational complexity on the satellite). If the initial concurrent user terminal count n is greater than 0, the idle spectrum resources are divided equally into n parts. If the initial state flag is 0, the idle spectrum resources are divided equally into m parts according to the concurrent user terminal count (second concurrent user terminal count) m.

[0039] Step 3: The satellite receives random access requests sent by user terminals and allocates resources based on the resource allocation results.

[0040] In one embodiment of this application, when the satellite receives a random access request sent by a user terminal, it determines whether there are idle spectrum resources; if there are idle spectrum resources, it allocates spectrum resources to each user terminal that sent the random access request; the satellite divides each time interval into multiple time slots and allocates the multiple time slots to each user terminal that sent the random access request.

[0041] In one possible implementation, the satellite receives random access requests from user terminals and allocates resources based on resource allocation results. The specific process is as follows: First, it determines whether there are any idle spectrum resources. If so, a spectrum resource is allocated to the requesting user. Then, based on the time slot length of the satellite system, the number of time slots within 15 minutes is calculated. For example, if one time slot in the satellite system is 1ms, then 15 minutes contains 900,000 time slots, and 900,000 time slots are allocated to the requesting user. If all spectrum resources are occupied, an access failure response is returned. The user terminal can obtain multiple time-frequency resources at once without repeatedly making random access requests, greatly reducing control signaling overhead.

[0042] Optionally, a two-step random access method can be adopted. First, the user terminal sends a random access request to the satellite, carrying the user terminal's latitude and longitude (which can be obtained through navigation and positioning algorithms), the user terminal's flag bit, and other conventional information. Then, the satellite sends a random access response to the user terminal, carrying the user terminal's flag bit, a flag bit indicating whether access was successful, and the time and frequency resources assigned to the user terminal.

[0043] In one embodiment of this application, after step 103, the method further includes: the satellite recording user statistics and sending them to the ground data center; determining whether the satellite is in an initial state; if the satellite is in an initial state, then step 100 is executed; otherwise, step 104 is executed: under normal satellite conditions, the ground data center integrates resource scheduling information based on user statistics every 15 minutes; the user statistics include the number of random accesses of user terminals received by the satellite in each time unit of each time interval, the access time of the accessed user terminals, and latitude and longitude information.

[0044] This application uses user statistics to calculate resource scheduling information. Specifically, user statistics are continuously updated through the random access process of user terminals during satellite operation, and the ground data center completes the calculation of resource scheduling information based on the user statistics.

[0045] In one possible implementation, step 104 specifically includes: Based on the number of random user accesses received by the satellite per minute, calculate the number of concurrent user terminals per satellite for the next 15 minutes. The number of concurrent user terminals can be calculated using the following formula. :

[0046] in, The number of random user terminal accesses received per minute for each satellite is given. The user terminal concurrency factor is set to [0,1] and is selected based on the actual business situation. The fewer the number of user terminals, the smaller the user terminal concurrency factor. The value of the user terminal concurrency factor is not restricted here.

[0047] Based on the access time and latitude / longitude information of the connected user terminals in the user statistics information, combined with satellite ephemeris and satellite orbit design parameters, the user terminal release group that needs to be released among the currently connected user terminals for each satellite is calculated. The user terminals that need to be released fall into two categories: the first is release due to invisibility, which is determined by calculating the visibility between the satellite and the user terminal; the second is release due to the expiration of allocated time slots, meaning that the allocated time slot is about to expire within the next 15 minutes, and the expiration time of the allocated time slot is the release time.

[0048] Resource scheduling information includes the number of concurrent user terminals (m), user release groups, and initial status flags.

[0049] Based on the above embodiments, after step 104, the method further includes: using the resource scheduling information obtained in step 104 as the first information, and repeating steps 1 to 3.

[0050] Based on the above embodiments, the resource scheduling information can be the resource scheduling information for the next 15 minutes calculated by the ground data center, which includes the following fields: Initial state flag: Defined as an integer, used to determine whether the satellite is in the initial state. If it is in the initial state, the flag is 1; otherwise, it is 0. Initial concurrent user terminals: Defined as an integer, calculated according to step 100 above, used for resource allocation of satellites in the initial state.

[0051] User terminal concurrency: Defined as an integer, calculated according to step 104 above, and used for satellite resource allocation under normal conditions.

[0052] User terminal release group: Defined as an array containing all user network identifiers and resource release times that need to be released. This network identifier is uniformly assigned by the satellite or network system, such as the C-RNTI (Cell-Radio Network Temporary Identifier, dynamically assigned by the base station to user equipment in a connected state) in 5G terrestrial networks. An example of a user terminal release group is [User terminal 1 identifier, resource release time, User terminal 2 identifier, resource release time].

[0053] This application integrates resource scheduling information through user statistics, allocating designated spectrum resources and multiple time slot resources to user terminals in one go, thereby reducing the number of interactions between satellites and user terminals and lowering system scheduling overhead. The satellite only needs to configure and allocate resources based on the resource scheduling information uploaded by the ground station, and a large amount of computation is completed by the ground data center. Compared with traditional resource allocation strategies, this greatly reduces the computational load on the satellite. Therefore, the technical solution of this application greatly solves the problem of limited satellite network resources and energy, and is suitable for situations where satellites and ground user terminals are in high-speed motion.

The determination module is used to determine the resource allocation result based on the received first information; The resource allocation module is used to receive random access requests sent by user terminals and allocate resources according to the resource allocation results.

As an example, the electronic device may include multiple processors. A processor may refer to one or more devices, circuits, and / or computing units for processing data (e.g., computer programs).
