Description

Technical Field

[0001] The present application relates to the field of satellite communication technology, and in particular to a method, device, electronic device and storage medium for allocating satellite communication bandwidth. Background Art

[0002] With the continuous development of satellite technology, satellite communication technology has become increasingly mature. It has now been achieved that satellites operating at different altitudes, such as high-orbit satellites and low-orbit satellites, use ground signal gateways as data relays to provide communication services for ground terminals and flight terminals. It can even be achieved without the use of ground signal gateways as data relays, but directly through satellites as data relays to provide communication services for ground terminals and flight terminals.

[0003] In order to realize data transmission between the terminal and the satellite, a certain bandwidth needs to be allocated to each terminal, and the bandwidth is generally a fixed bandwidth; since the bandwidth is fixed bandwidth, when the amount of data that the terminal needs to transmit is too large, the fixed bandwidth cannot meet the communication needs of the terminal. At this time, it is necessary to add spare bandwidth for the terminal to meet the communication needs of the terminal.

[0004] However, the inventors of the present application have discovered that the conventional method of adding spare bandwidth to a terminal may result in the addition of too much spare bandwidth to meet the communication needs of the terminal. Although the communication needs of the terminal are met, this also results in a waste of communication bandwidth resources and low utilization of the communication bandwidth.

[0040] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the drawings in the embodiments of the present application are collected below to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] An embodiment of the present application provides a method for allocating satellite communication bandwidth, which can be executed by an electronic device, wherein the electronic device can be a server, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server that provides cloud computing services; the server can be installed on a satellite.

[0043] Reference Figure 1 A method for allocating satellite communication bandwidth includes: step S101, step S102 and step S103, wherein:

[0044] S101, determining a spare bandwidth of a target terminal, and determining a bandwidth usage of the spare bandwidth in at least two adjacent unit time periods.

[0045] In some embodiments, the spare bandwidth is the bandwidth allocated to the target terminal when its corresponding current bandwidth is insufficient; the bandwidth usage is the amount of bandwidth used by the target terminal in a unit time period during data communication using the spare bandwidth.

[0046] There can be multiple terminals that establish communication connections with the same satellite, and each terminal is configured with a fixed bandwidth, namely the current bandwidth; the current bandwidth can meet the daily communication needs of the terminal; however, during the terminal's data communication process, there is a period of time when the amount of data required to be transmitted exceeds the daily communication. At this time, the current bandwidth cannot meet the communication needs. For this reason, you can consider adding a backup bandwidth to the terminal to meet the target terminal's need to transmit data exceeding the daily communication.

[0047] Since the backup bandwidth is used as a temporary bandwidth for the target terminal, the backup bandwidth needs to be temporarily determined and configured. Therefore, it is necessary to consider whether the target satellite that establishes a communication connection with the target terminal has remaining bandwidth at the moment when the backup bandwidth needs to be configured; when the remaining bandwidth of the target satellite meets the demand, the backup bandwidth is configured for the target terminal; that is, when the electronic device determines the backup bandwidth of the target terminal, the electronic device first needs to clarify the remaining bandwidth of the target satellite. When the remaining bandwidth meets the preset demand, the electronic device determines the backup bandwidth of the target terminal from the remaining bandwidth and configures the backup bandwidth for the target terminal.

[0048] When the target terminal uses the spare bandwidth for data transmission, the electronic device monitors the usage of the spare bandwidth in real time and determines the bandwidth usage of the spare bandwidth within each preset unit time period; subsequently, based on the bandwidth usage, it further determines whether it is necessary to further increase the bandwidth for the target terminal.

[0049] S102, obtaining the data volume, data type, and first data importance level of first transmission data of the target terminal.

[0050] In some embodiments, the first transmission data is the data that the target terminal is transmitting with the aid of the target satellite. The size of the bandwidth allocated to the target terminal needs to take into account the data volume, data type and first data importance level of the first transmission data of the target terminal; the larger the data volume of the first transmission data, the larger the bandwidth required to complete the data transmission within a specific time period; different data types have different fixed byte sizes and different adapted bandwidth sizes; the larger the data importance level, the higher the time required for transmission completion and the stability of transmission. Therefore, when the standby bandwidth of the target terminal cannot meet the communication needs and the bandwidth needs to be increased, the data volume, data type and first data importance level of the first transmission data of the target terminal need to be considered, that is, the electronic device obtains the data volume, data type and first data importance level of the first transmission data from the target terminal.

[0051] S103, determining a target compensation bandwidth based on bandwidth usage, data volume, data type, and data importance level, and allocating the target compensation bandwidth to a target terminal.

[0052] In some embodiments, the electronic device determines whether the target terminal needs to add bandwidth on the basis of using the spare bandwidth based on the bandwidth usage and the data type; when the bandwidth usage and the data type meet the preset conditions, the electronic device determines the bandwidth that needs to be added, i.e., the target compensation bandwidth, based on the data volume and the first data importance level; then, the electronic device controls the target satellite to add the target compensation bandwidth to the target terminal, so that the target terminal can ensure the stability of communication transmission during the transmission process; in addition, by preliminarily determining the spare bandwidth, and when the spare bandwidth meets the preset conditions, i.e., when the bandwidth needs to be added, further determining the method of adding bandwidth by decomposing segments of the target compensation bandwidth, the occurrence of bandwidth allocated to the terminal being idle is reduced, and the bandwidth utilization rate is improved.

[0053] The present application provides a method for allocating satellite communication bandwidth. When the current bandwidth of a target terminal reaches a preset bandwidth, it indicates that the current bandwidth of the target terminal cannot meet the demand for transmitting first transmission data, and bandwidth needs to be increased for the target terminal. Then, an electronic device determines a spare bandwidth from the remaining bandwidth of the target satellite and allocates the spare bandwidth to the target terminal. Subsequently, the target terminal uses the bandwidth with the increased spare bandwidth for data transmission, and the electronic device determines the usage of the spare bandwidth in real time, that is, determines the bandwidth usage of the spare bandwidth in at least two adjacent unit time periods. At the same time, the electronic device obtains the data volume, data type and first data importance level of the first transmission data of the target terminal. The electronic device determines a target compensation bandwidth based on the bandwidth usage, data volume, data type and first data importance level, and then the electronic device allocates the target compensation bandwidth to the target terminal, thereby realizing multiple bandwidth allocations for the target terminal in a phased manner, while ensuring the stability of data transmission of the target terminal, improving the utilization rate of the communication bandwidth.

[0054] In step S101, the backup bandwidth of the target terminal is determined, including: obtaining the current bandwidth of the target terminal; generating a bandwidth allocation instruction when the current bandwidth reaches the first preset bandwidth; obtaining the first remaining bandwidth of the target satellite based on the bandwidth allocation instruction; and determining a bandwidth equal to the second preset bandwidth from the first remaining bandwidth as the backup bandwidth when the first remaining bandwidth is not less than the second preset bandwidth.

[0055] In some embodiments, whether it is necessary to add spare bandwidth to the target terminal needs to consider the bandwidth already allocated to the target terminal, that is, the current bandwidth usage. Therefore, the electronic device first obtains the current bandwidth corresponding to the target terminal and monitors the current bandwidth usage in real time.

[0056] That is, the electronic device is preset with a first preset bandwidth, and the electronic device compares the current bandwidth obtained with the first preset bandwidth in real time; when it is determined that the current bandwidth reaches the first preset bandwidth, it indicates that the bandwidth usage of the target terminal has reached the point where additional backup bandwidth is required, and the electronic device then generates a bandwidth increase instruction and sends the bandwidth increase instruction to the target satellite. The target satellite responds to the bandwidth increase instruction and sends the remaining bandwidth of the current target underestimated satellite, that is, the first remaining bandwidth, to the electronic device.

[0057] The electronic device compares the first remaining bandwidth with the second preset bandwidth. When it is determined that the first remaining bandwidth is not less than the second preset bandwidth, it indicates that the first remaining bandwidth of the target satellite can meet the demand for adding backup bandwidth to the target terminal. The electronic device then determines a bandwidth equal to the second preset bandwidth from the first remaining bandwidth, and determines the bandwidth as the backup bandwidth. At the same time, the electronic device generates a backup bandwidth allocation instruction, and sends the backup bandwidth allocation instruction to the target satellite. The target satellite responds to the backup bandwidth allocation instruction and allocates the backup bandwidth to the target terminal.

[0058] In some embodiments, the first preset bandwidth is a condition for determining whether it is necessary to add a backup bandwidth to the current bandwidth, and its setting can be subjectively set by a technician based on the experience of historical data transmission of the target terminal, and the specific setting value is not specifically limited in the embodiment of the application, but the maximum value of the first preset bandwidth does not exceed the current bandwidth. The second preset bandwidth is a pre-set amount of backup bandwidth that needs to be added to the target terminal, and its setting can be subjectively set by a technician based on the experience of historical transmission of the target terminal, and the specific value is not specifically limited in the embodiment of the application.

[0059] In some embodiments, when the electronic device determines that the bandwidth usage of the backup bandwidth in at least two adjacent unit time periods is less than the preset minimum bandwidth usage, it generates a second preset bandwidth adjustment instruction and sends the second preset bandwidth adjustment instruction to the main control terminal. The technician modifies the second preset bandwidth based on the second preset bandwidth adjustment instruction displayed on the main control terminal.

[0060] In step S101, at least two adjacent unit time periods each include a plurality of sub-time nodes; determining the bandwidth usage of the standby bandwidth within at least two adjacent unit time periods includes: obtaining a plurality of sub-bandwidth usages corresponding to the standby bandwidth; wherein the plurality of sub-bandwidth usages have a corresponding relationship with the plurality of sub-time nodes; filtering out a maximum sub-bandwidth usage from the plurality of sub-bandwidth usages, and determining the maximum sub-bandwidth usage as the bandwidth usage.

[0061] In some embodiments, the bandwidth usage is the maximum amount of data transmitted by the target terminal through the network within a unit time. When determining the bandwidth usage of the standby bandwidth within a unit time period, in order to ensure the accuracy and rationality of the determined bandwidth usage, the set unit time period may include multiple sub-time nodes, and the electronic device monitors the bandwidth usage at each sub-time node; that is, the electronic device obtains the sub-bandwidth usage of each sub-time node; then, the electronic device sorts the sub-bandwidth usage based on the time, and selects the maximum sub-bandwidth usage from multiple sub-bandwidth usage flows, and determines the maximum sub-bandwidth usage as the bandwidth usage, that is, the maximum sub-bandwidth usage is used as the bandwidth usage of the standby bandwidth within the unit time period.

[0062] In some embodiments, in step S103, the target compensation bandwidth is determined based on the bandwidth usage, data volume, data type and the first data importance level, including: when the data type is a preset data type and the bandwidth usage is not less than the preset bandwidth usage, generating a remaining bandwidth call instruction; determining the current remaining bandwidth based on the remaining bandwidth call instruction; determining the target compensation bandwidth based on the data volume, the first data importance level and the current remaining bandwidth.

[0063] In some embodiments, data type refers to the format and type of data, such as integers, floating point numbers, characters, images, audio and video, etc., and each data type has its specific size and structure; the first data importance level is the importance of the stability and efficiency of the first output data transmission; the first data importance level of the first transmission data can be subjectively set by the technician with reference to the data volume and data type of the first transmission data.

[0064] 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 that needs to be set to a certain extent. Therefore, the electronic device can judge whether it is necessary to increase the bandwidth on the basis of the backup bandwidth based on the data type. That is, the electronic device compares the data type with the preset data type. When it is determined that the data type is the preset data type, it indicates that the first transmission data has a large demand for bandwidth. At the same time, the electronic device compares the bandwidth usage with the first bandwidth usage.

[0065] When the data type is a preset data type and the bandwidth usage is not less than the preset bandwidth usage, it indicates that when the target terminal is transmitting the first transmission data, due to the influence of the data type, there may be a situation where the bandwidth cannot meet the transmission demand in the subsequent data transmission process, and the usage of the spare bandwidth also determines that the bandwidth usage has reached the level where additional bandwidth needs to be allocated; then, the electronic device generates a remaining bandwidth retrieval instruction and sends the remaining bandwidth retrieval instruction to the target satellite.

[0066] The target satellite responds to the remaining bandwidth retrieval instruction and sends the current remaining bandwidth to the electronic device. After determining the current remaining bandwidth, the electronic device determines the target compensation bandwidth from the current remaining bandwidth based on the data volume and the first data importance level.

[0067] In some embodiments, based on the remaining bandwidth retrieval instruction, the current remaining bandwidth is determined, specifically including: based on the remaining bandwidth retrieval instruction, obtaining the second remaining bandwidth of the target satellite corresponding to the target terminal, and determining multiple third remaining bandwidths; wherein the third remaining bandwidth is the remaining bandwidth of other terminals other than the target terminal belonging to the same target satellite; and determining the second remaining bandwidth and the multiple third remaining bandwidths as the current remaining bandwidth.

[0068] In some embodiments, the second remaining bandwidth is the remaining bandwidth of the target satellite after allocating bandwidth to all terminals. There are multiple terminals that establish communication connections with the target satellite, and the data that each terminal needs to transmit and the time node of data transmission are different. Therefore, some terminals that establish communication connections with the target satellite have a certain bandwidth that is idle at the current moment. Then, when the electronic device determines the current remaining bandwidth based on the remaining bandwidth call instruction, the idle bandwidth of some terminals can be taken into account, that is, the electronic device obtains the second remaining bandwidth and multiple third remaining bandwidths of the target satellite corresponding to the target terminal based on the remaining bandwidth call instruction, and determines the second remaining bandwidth and multiple third remaining bandwidths as the current remaining bandwidth.

[0069] In some embodiments, the target compensation bandwidth is determined based on the data volume, the first data importance level and the current remaining bandwidth, including: determining the current bandwidth demand of the target terminal based on the data volume and the data importance level; determining the second data importance level of the second transmission data corresponding to the multiple remaining bandwidths respectively when the current bandwidth demand is less than the current remaining bandwidth and the current remaining bandwidth demand is not less than the second remaining bandwidth; determining the target compensation bandwidth based on the second data importance level and the multiple remaining bandwidths.

[0070] In some embodiments, a target compensation bandwidth is determined based on the second data importance level and multiple remaining bandwidths, including: sorting multiple remaining bandwidths according to a sorting rule from small to large according to the second data importance level, and giving priority to the remaining bandwidths corresponding to the second data importance level with a smaller level, to determine at least one target remaining bandwidth from the multiple remaining bandwidths; and determining the target compensation bandwidth based on the at least one target remaining bandwidth and the second remaining bandwidth.

[0071] In some embodiments, the current bandwidth demand is the bandwidth demand that the target terminal needs to add on the basis of the current bandwidth and the backup bandwidth. The data volume reflects the volume of the first transmission data; the data importance level corresponds to the transmission requirement of the first transmission data, that is, the required transmission duration. Therefore, the electronic device can determine the current bandwidth demand of the target terminal based on the data volume and the data importance level, wherein the electronic device retrieves the required transmission duration corresponding to the data importance level, and determines the total bandwidth required for the first transmission data based on the required transmission duration and the data volume, and then determines the current bandwidth demand of the target terminal based on the total bandwidth and the current bandwidth and backup bandwidth of the first transmission data at the current time node.

[0072] The electronic device will determine the current demand and compare it with the current remaining bandwidth. When it is determined that the current bandwidth demand is less than the current bandwidth, it indicates that the current remaining bandwidth can meet the needs of increasing the bandwidth for the target terminal. At the same time, the electronic device will compare the current remaining bandwidth demand with the second remaining bandwidth. When it is determined that the current remaining bandwidth demand is not less than the second remaining bandwidth, it indicates that only using the second remaining bandwidth corresponding to the target satellite cannot meet the needs of increasing the bandwidth for the target terminal, and it is necessary to consider the idle bandwidth of other terminals connected to the target satellite, that is, the third remaining bandwidth.

[0073] Since the idle bandwidths of other terminals that establish connections with the target satellite are different in size, and whether the idle bandwidth needs to be used later is different, and the importance levels of data that are subsequently transmitted using the idle bandwidth are different, it is necessary to screen out terminals that meet the requirements of adding bandwidth to the target terminal and the idle bandwidth of the terminal from multiple terminals with idle bandwidth; that is, when the current bandwidth demand is less than the current remaining bandwidth and the current remaining bandwidth demand is not less than the second remaining bandwidth, the electronic device determines the second data importance level of the second transmission data corresponding to the multiple remaining bandwidths respectively; sorts the multiple remaining bandwidths from small to large according to the second data importance level to filter out the filtering rules for the remaining bandwidth with low second data importance level, and filters out at least one target remaining compensation bandwidth from the multiple remaining bandwidths, and then the electronic device integrates the at least one target remaining bandwidth and the second remaining bandwidth to determine the target compensation bandwidth; wherein the target compensation bandwidth must be greater than the current bandwidth demand.
