It should be understood that the specific embodiments described herein are intended to explain the present application, but not to limit the present application. The present application can be implemented without some of the specific details by those skilled in the art. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

[0026] It should be noted that, in this document, relational terms such as first and second, and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, an element defined by the phrase "comprising a... " does not exclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0027] To solve the problems in the prior art, embodiments of the present application provide a bandwidth adjustment method, device, electronic device, medium and program product. First, the bandwidth adjustment method provided by the embodiments of the present application will be introduced.

[0028] Figure 1 A flowchart of a bandwidth adjustment method provided by an embodiment of the present application is shown. As shown in Figure 1 The bandwidth adjustment method provided by the embodiments of the present application includes the following steps 101-104, wherein:

[0029] Step 101, determining a first transmission rate corresponding to each of a plurality of users accessing a satellite in a first period.

[0030] The length of the first period can be flexibly set according to actual conditions, which is not limited herein. The first transmission rate can be an uplink rate or a downlink rate, which is not limited herein. It should be noted that the user in the embodiments of the present application can be understood as a terminal.

[0031] In step 102, a weight corresponding to each of the users is determined according to a first transmission rate of each of the users.

[0032] For example, step 102 can include obtaining a second bandwidth used by each of the users and a mapping relationship, the mapping relationship including a correspondence between a bandwidth, a maximum transmission rate and a minimum transmission rate.

[0033] The maximum transmission rate and the minimum transmission rate corresponding to each of the second bandwidths are obtained from the mapping relationship.

[0034] The weight corresponding to each of the users is determined according to the first transmission rate of each of the users and the maximum transmission rate and the minimum transmission rate corresponding to the second bandwidth of the user.

[0035] In the above, the mapping relationship can be pre-set, and the mapping relationship can include a plurality of different bandwidths and the maximum transmission rate and the minimum transmission rate corresponding to each of the bandwidths. The maximum transmission rate and the minimum transmission rate corresponding to each of the bandwidths can be set according to actual conditions or experience, which is not limited herein.

[0036] The maximum transmission rate and the minimum transmission rate corresponding to each of the second bandwidths of the user can be obtained from the mapping relationship. The first transmission rate of the user can be regarded as an actual transmission rate. The first transmission rate of the user is compared with the maximum transmission rate and the minimum transmission rate corresponding to the second bandwidth of the user to determine the weight corresponding to the user. For example, for any first user in the plurality of users, if the first transmission rate of the first user is greater than or equal to the maximum transmission rate R ibmax of the first user, it is determined that the weight of the first user is a first value; if the first transmission rate of the first user is less than the minimum transmission rate R ibmin of the first user, it is determined that the weight of the first user is a second value, the second value being less than the first value. The first value is w, and the second value is -w / 2, where w is the weight corresponding to the first user when the first user is allocated the second bandwidth.

[0037] In step 103, a first bandwidth corresponding to each of the users is obtained by allocating a current remaining bandwidth of the satellite to each of the users according to the weight of each of the users.

[0038] The first bandwidth corresponding to each of the users is calculated according to the following expression:

[0039]

[0040] wherein, is the first bandwidth corresponding to the user i in the first period t, a sum of weights determined according to the first transmission rate for each of the users, a weight determined according to the first transmission rate for the user i in the first period t, B res the remaining bandwidth.

[0041] the remaining bandwidth B res is determined according to the following expression:

[0042] B res = B Total -B Re -B Used

[0043] wherein B Total is the total bandwidth provided by the satellite, B Re is the bandwidth reserved for new user access, B Used is a sum of the second bandwidths used by each of the users. This can ensure that new users can successfully access and obtain sufficient bandwidth resources, and guarantee normal operation of the accessed users and meet their priority requirements when subsequent allocation of the remaining bandwidth is performed.

[0044] Step 104: adjusting the bandwidth allocated to the users according to the first bandwidth corresponding to each of the users.

[0045] For example, for any second user in the plurality of users, if a sum of the first bandwidth of the second user and the second bandwidth used by the second user is greater than a preset maximum allocation bandwidth, the second user is allocated the maximum allocation bandwidth; if the sum of the first bandwidth of the second user and the second bandwidth used by the second user is less than the maximum allocation bandwidth, the second user is allocated a target bandwidth, and the target bandwidth is the sum of the first bandwidth of the second user and the second bandwidth used by the second user.

[0046] In the above, the maximum allocation bandwidth can be preset, and the maximum allocation bandwidth is the maximum bandwidth that a single user can obtain. If the first bandwidth allocated to the user exceeds the maximum allocation bandwidth, the user is only allocated the maximum allocation bandwidth, and the remaining bandwidth is reserved for the next period of allocation processing.

[0047] In the embodiments of the present application, the first transmission rate of each of a plurality of users accessing a satellite in a first period is determined; the weight corresponding to each of the users is determined according to the first transmission rate of each of the users; the first bandwidth corresponding to each of the users is obtained by allocating the current residual bandwidth of the satellite according to the weight of each of the users; and the bandwidth allocated to the users is adjusted according to the first bandwidth corresponding to each of the users. In this way, the weight is determined according to the first transmission rate of each of the users, and the current residual bandwidth of the satellite is allocated according to the weight, so that the bandwidth allocated to the users is adjusted according to the first bandwidth, the redundant bandwidth resource is allocated to the users, the dynamic allocation of resources is achieved, the utilization rate of the residual bandwidth resource is improved, and the experience perception of the users is improved.

[0048] The method in the embodiments of the present application is a method for dynamically allocating wideband resources based on a near-earth satellite communication system.

[0049] The bandwidth adjustment method provided by the present application is illustrated as follows. Figure 2 As shown in the following, the bandwidth adjustment method provided by the present application includes the following steps.

[0050] In step 201, the number of accessed terminals and the priority of the service used by the terminals are obtained; the total bandwidth B that can provide the service is set. Total In order to ensure that new users can access, the bandwidth resource B reserved for the access of new users is set. Re The number n of accessed users and the priority p of the service of the users are obtained, and the scheduling weight w of the users is set. The value p is a value allocated in the user system, and the greater the value, the higher the priority and the higher the scheduling weight.

[0051] In step 202, the current bandwidth used by the accessed terminals is calculated; the current bandwidth used by the ith user is set as B i The current bandwidth of the users is obtained, and the total bandwidth used by the users is

[0052] In step 203, the resource demand of the terminals is judged and the scheduling weight is set; a bandwidth rate matching table (which can be set according to experience or actual demand) is set, and the average rate R of the users in a unit time t is i t If the current bandwidth of the user is greater than or equal to the rate R corresponding to the bandwidth, the user is considered to have an increasing resource demand. ibmax If the current bandwidth of the user is less than R ibmin , the user is considered to have a decreasing resource demand.

[0053] For each user, the resource demand of the user is judged in the period t, and the period t ends. The scheduling weight of the user can be set according to the actual situation, and one suggestion is as follows.

[0054] 1) If the user rate at the end of the period is R i t ≥ R ibmax , then the user scheduling weight increment is set according to the priority of the user service

[0055] 2) If the user rate at the end of the period is R i t < R ibmin , then the user scheduling weight increment is set according to the priority of the user service

[0056] 3) If it is judged that no adjustment is needed, then the weight increment is

[0057] The sum of the weights of each terminal after adjustment

[0058] Step 204, the resource bandwidth that can be further allocated to each terminal is calculated: B res = B Total -B Re -B Used Based on the greedy algorithm, the remaining resources are allocated to the demand users, and the bandwidth resource that can be allocated to each user is If the bandwidth allocated to the user exceeds the maximum allocation bandwidth of a single user, only the maximum bandwidth of a single user is allocated to the user, and the remaining resources are reserved for the next period of allocation processing.

[0059] Step 205, the broadband resource of the terminal is adjusted and the next period is started: according to the allocable bandwidth of the user, in combination with the closest value in the scheduling algorithm, the resource is adjusted, and the data collection for the dynamic resource allocation of the next period is started.

[0060] The above method allocates redundant bandwidth resources to the users who have accessed the satellite based on the priority of their services, the allocated resource bandwidth, and the service transmission data volume in the evaluation time through the calculation of the greedy algorithm, so as to achieve dynamic allocation of resources and improve the user experience.

[0061] The bandwidth adjustment method provided in the application has the following advantages:

[0062] 1. Ensure that new users can successfully access and obtain sufficient bandwidth resources.

[0063] 2. Ensure that the services of the accessed users run normally and meet their priority requirements.

[0064] 3. Avoid the average rate of the users being too low, which leads to a decline in service quality or damage to user experience.

[0065] 4. Prevent resource allocation inequality, ensure fairness and rights protection of all users.

[0066] 5. Ensure accuracy and timeliness of scheduling algorithm to realize dynamic allocation and optimization of resources.
