Referring to fig. 1, a method for allocating a satellite communication bandwidth includes steps S101, S102 and S103, wherein,
S101, determining the standby bandwidth of the target terminal, and determining the bandwidth usage of the standby bandwidth in at least two adjacent unit time periods.
In some embodiments, the standby bandwidth is the bandwidth increased by the target terminal when the corresponding current bandwidth is insufficient, and the bandwidth usage is the bandwidth used by the target terminal in the process of using the standby bandwidth for data communication in a unit time period.
The terminal which establishes communication connection with the same satellite can be multiple, each terminal is configured with a fixed bandwidth, namely a current bandwidth, the current bandwidth can meet daily communication requirements of the terminal, however, in the process of data communication of the terminal, the situation that the current bandwidth cannot meet the communication requirements occurs when the data quantity which exceeds the daily communication needs to be transmitted in a certain period of time exists, and therefore, the terminal can be considered to be additionally provided with a standby bandwidth to meet the requirements of the target terminal for transmitting the data quantity which exceeds the daily communication.
The standby bandwidth is used as a temporary bandwidth of the target terminal, the standby bandwidth needs to be determined and configured temporarily, so that whether the target satellite which is in communication connection with the target terminal has residual bandwidth needs to be considered at the moment when the standby bandwidth needs to be configured currently, the standby bandwidth of the target terminal is configured under the condition that the residual bandwidth of the target satellite meets the requirement, namely, when the electronic equipment determines the standby bandwidth of the target terminal, the electronic equipment firstly needs to determine the residual bandwidth of the target satellite, and when the residual bandwidth meets the preset requirement, the electronic equipment determines the standby bandwidth of the target terminal from the residual bandwidth and configures the standby bandwidth of the target terminal.
In the process of data transmission by using the standby bandwidth by the target terminal, the electronic equipment monitors the use condition of the standby bandwidth in real time, determines the bandwidth use amount of the standby bandwidth in each preset unit time period, and further judges whether the bandwidth needs to be further increased for the target terminal based on the bandwidth use amount.
S102, acquiring the data quantity, the data type and the first data importance level of the first transmission data of the target terminal.
In some embodiments, the first transmission data is data that the target terminal is transmitting via the target satellite. The method comprises the steps of allocating a bandwidth to a target terminal, considering the data quantity, the data type and the first data importance level of first transmission data of the target terminal, wherein the larger the data quantity of the first transmission data is, the larger the bandwidth is required to be used for completing data transmission in a specific time period, the different data types are different in fixed byte size, the different in adaptive bandwidth size, and the larger the data importance level is, the higher the transmission completion time and the transmission stability requirement are, so that when the spare bandwidth of the target terminal cannot meet the communication requirement and the bandwidth needs to be increased, the data quantity, the data type and the first data importance level of the first transmission data of the target terminal are required to be considered, namely, the electronic equipment acquires the data quantity, the data type and the first data importance level of the first transmission data from the target terminal.
And S103, determining a target compensation bandwidth based on the bandwidth usage amount, the data type and the data importance level, and distributing the target compensation bandwidth to the target terminal.
In some embodiments, the electronic device determines whether the target terminal needs to increase the bandwidth based on the bandwidth usage amount and the data type, determines the bandwidth to be increased based on the data amount and the first data importance level when the bandwidth usage amount and the data type meet the preset conditions, namely, the target compensation bandwidth, then controls the target satellite to increase the target compensation bandwidth to the target terminal so as to ensure the stability of communication transmission in the transmission process of the target terminal, and in addition, determines the bandwidth increase mode of the decomposition section of the target compensation bandwidth by preliminarily determining the standby bandwidth and further determining the bandwidth increase mode of the target compensation bandwidth when the standby bandwidth meets the preset conditions, namely, the bandwidth is required to be increased, so that the situation that the bandwidth is allocated to the terminal in idle is reduced, and the utilization rate of the bandwidth is improved.
The application provides a satellite communication bandwidth allocation method, which is characterized in that under the condition that the current bandwidth of a target terminal reaches a preset bandwidth, the current bandwidth of the target terminal cannot meet the requirement of transmitting first transmission data, bandwidth needs to be increased for the target terminal, then an electronic device determines standby bandwidth from the residual bandwidth of the target satellite and allocates the standby bandwidth to the target terminal, the subsequent target terminal uses the bandwidth with the increased standby bandwidth for data transmission, the electronic device determines the use condition of the standby bandwidth in real time, namely determines the bandwidth use amount of the standby bandwidth in at least two adjacent unit time periods, and meanwhile, the electronic device acquires the data amount, the data type and the first data importance level of first transmission data of the target terminal, determines target compensation bandwidth based on the bandwidth use amount, the data type and the first data importance level, and then the electronic device allocates the target compensation bandwidth to the target terminal, so that multiple bandwidth increase allocation is carried out on the target terminal in a staged mode, the stability of data transmission of the target terminal is ensured, and the communication bandwidth utilization rate is improved.
In step S101, determining a standby bandwidth of a target terminal comprises obtaining a current bandwidth of the target terminal, generating a bandwidth allocation increasing instruction when the current bandwidth reaches a first preset bandwidth, obtaining a first residual bandwidth of a target satellite based on the bandwidth allocation increasing instruction, and determining a bandwidth equal to a second preset bandwidth from the first residual bandwidth as the standby bandwidth when the first residual bandwidth is not smaller than the second preset bandwidth.
In some embodiments, whether the spare bandwidth needs to be increased or not for the target terminal needs to be allocated, that is, the bandwidth already allocated to the target terminal, that is, the use condition of the current bandwidth needs to be considered, so the electronic device first obtains the current bandwidth corresponding to the target terminal, and monitors the use condition of the current bandwidth in real time.
The electronic equipment is provided with a first preset bandwidth in advance, the electronic equipment compares the acquired current bandwidth with the first preset bandwidth in real time, under the condition that the current bandwidth reaches the first preset bandwidth, the situation that the bandwidth use condition of the target terminal reaches the condition that the bandwidth needs to be increased is indicated, then the electronic equipment generates a bandwidth increasing instruction and sends the bandwidth increasing instruction to the target satellite, and the target satellite responds to the bandwidth increasing instruction and underestimates the residual bandwidth of the satellite at present, namely the first residual bandwidth is sent to the electronic equipment.
The electronic equipment compares the first residual bandwidth with the second preset bandwidth, and under the condition that the first residual bandwidth is not smaller than the second preset bandwidth, the electronic equipment indicates that the first residual bandwidth of the target satellite can meet the requirement of adding the available bandwidth to the target terminal, then the electronic equipment determines the bandwidth which is equal to the second preset bandwidth from the first residual bandwidth and determines the bandwidth as the standby bandwidth, and meanwhile, the electronic equipment generates a standby bandwidth adding instruction, sends the standby bandwidth adding instruction to the target satellite, underestimates the response of the satellite to the standby bandwidth adding instruction and distributes the standby bandwidth to the target terminal.
In some embodiments, the first preset bandwidth is a condition for determining whether to add an available bandwidth to the current bandwidth, where the setting may be set subjectively by a technician based on experience of historical data transmission of the target terminal, and the specific setting is not specifically limited in the embodiments of the present application, but the maximum value of the first preset bandwidth does not exceed the current bandwidth. The second preset bandwidth is a preset amount of bandwidth to be allocated to the target terminal, and the setting of the second preset bandwidth can be set subjectively by a technician based on experience of historical transmission of the target terminal, and the specific value is not limited in particular.
In some embodiments, when the electronic device determines that the bandwidth usage amounts of the standby bandwidths in at least two adjacent unit time periods are smaller than the preset minimum bandwidth usage amount, a second preset bandwidth adjustment instruction is generated, the second preset bandwidth adjustment instruction is sent to the master control terminal, and the technician modifies the second preset bandwidth based on the second preset bandwidth adjustment instruction displayed by the master control terminal.
In step S101, at least two adjacent unit time periods each comprise a plurality of sub-time nodes, and determining bandwidth usage of standby bandwidth in at least two adjacent unit time periods comprises obtaining a plurality of sub-bandwidth usage corresponding to the standby bandwidth, wherein the plurality of sub-bandwidth usage has a corresponding relation with the plurality of sub-time nodes, screening out the maximum sub-bandwidth usage from the plurality of sub-bandwidth usage, and determining the maximum sub-bandwidth usage as the bandwidth usage.
In some embodiments, the bandwidth usage is the maximum amount of data that the target terminal transmits over the network per unit time. When determining the bandwidth usage of the standby bandwidth in the unit time period, in order to ensure the accuracy and the rationality of the determined bandwidth usage, the set unit time period can comprise a plurality of sub-time nodes, the electronic equipment monitors the bandwidth usage in each sub-time node, namely the electronic equipment acquires the sub-bandwidth usage of each sub-time node, then the electronic equipment sorts the sub-bandwidth usage based on time, screens out the maximum sub-bandwidth usage from a plurality of sub-bandwidth usage flows, and determines the maximum sub-bandwidth usage as the bandwidth usage, namely the maximum sub-bandwidth usage is used as the bandwidth usage of the standby bandwidth in the unit time period.
In some embodiments, determining the target compensation bandwidth based on the bandwidth usage amount, the data type, and the first data importance level in step S103 includes generating a residual bandwidth fetch instruction if the data type is a preset data type and the bandwidth usage amount is not less than the preset bandwidth usage amount, determining a current residual bandwidth based on the residual bandwidth fetch instruction, and determining the target compensation bandwidth based on the data amount, the first data importance level, and the current residual bandwidth.
In some embodiments, the data types refer to formats and types of data, such as integers, floating point numbers, characters, images, audio and video, each data type has a specific size and structure, the first data importance level is the importance level of the stability and efficiency of the transmission of the first output data, and the first data importance level of the first transmission data can be subjectively set by a technician with reference to the data amount and data type of the first transmission data.
The data type can intuitively reflect the size of the data, and the size of the data can determine the size of the data bandwidth to be set to a certain extent, so that the electronic device can increase the bandwidth on the basis of judging whether the spare bandwidth is needed or not based on the data type, namely, the electronic device compares the data type with the preset data type, and under the condition that the data type is judged to be the preset data type, the electronic device indicates that the first transmission data has larger requirement on the bandwidth, and meanwhile, the electronic device compares the bandwidth use amount with the first bandwidth use amount.
Under the condition that the data type is a preset data type and the bandwidth usage amount is not less than the preset bandwidth usage amount, the condition that the bandwidth cannot meet the transmission requirement in the subsequent data transmission process due to the influence of the data type in the process of transmitting the first transmission data is indicated, the bandwidth usage amount is judged to reach the extent that the bandwidth needs to be increased from the use condition of the standby bandwidth, and then the electronic equipment generates a residual bandwidth calling instruction and sends the residual bandwidth calling instruction to the target satellite.
The target satellite responds to the residual bandwidth calling instruction, the current residual bandwidth is sent to the electronic equipment, and the electronic equipment determines the target compensation bandwidth from the current residual bandwidth based on the data quantity and the first data importance level under the condition that the current residual bandwidth is determined.

In some embodiments, the second remaining bandwidth is the bandwidth that the target satellite remains after allocating the bandwidth of all terminals. The method comprises the steps that a plurality of terminals are connected with a target underestimation satellite in a communication mode, data to be transmitted and time nodes for data transmission of each terminal are different, so that certain terminals are in an idle state when certain bandwidths exist at the current moment, the electronic equipment can take the idle bandwidths of certain terminals into consideration when determining the current residual bandwidths based on residual bandwidth calling instructions, namely, the electronic equipment obtains second residual bandwidths and a plurality of third residual bandwidths of the target satellite corresponding to the target terminal based on the residual bandwidth calling instructions, and the second residual bandwidths and the third residual bandwidths are determined to be the current residual bandwidths.
In some embodiments, determining the target compensation bandwidth based on the data amount, the first data importance level, and the current residual bandwidth includes determining a current bandwidth demand of the target terminal based on the data amount and the data importance level, determining a second data importance level of second transmission data corresponding to each of the plurality of residual bandwidths if the current bandwidth demand is less than the current residual bandwidth and the current residual bandwidth demand is not less than the second residual bandwidth, and determining the target compensation bandwidth based on the second data importance level and the plurality of residual bandwidths.

In some embodiments, the current bandwidth demand is a demand of bandwidth that the target terminal needs to add on the basis of the current bandwidth and the spare bandwidth. The electronic equipment can determine the current bandwidth demand of the target terminal based on the data quantity and the data importance level, wherein the electronic equipment invokes the time length of the transmission requirement corresponding to the data importance level, determines the total bandwidth required by the first transmission data based on the time length of the transmission requirement and the data quantity, and then determines the current bandwidth demand of the target terminal based on the total bandwidth and the current bandwidth and the standby bandwidth of the first transmission data of the current time node.
