Description

Technical Field

[0001] This application relates to the field of satellite communication technologies, and particularly to a communication method, device, and storage medium based on the integration of low-earth orbit (LEO) and geostationary orbit (GEO) satellites. Background Art

[0002] Direct satellite communication for mobile phones is an important breakthrough in the communication field in recent years, aiming to achieve seamless communication globally through satellites. Especially in scenarios where traditional mobile communication networks cannot be used, such as remote areas or natural disasters, communication can also be achieved through direct satellite communication for mobile phones.

[0003] The current types of direct satellite communication for mobile phones include direct connection between mobile phones and GEO satellites and direct connection between mobile phones and LEO satellites. However, both GEO satellites and LEO satellites have certain disadvantages. For GEO satellites, due to their large distance from the Earth, the latency of GEO satellites is relatively large. Further, due to their large coverage area, the bandwidth resources of GEO satellites are limited, and the bandwidth utilization rate is relatively low. For LEO satellites, due to their close distance to the Earth and high operating speed, the direct connection time between LEO satellites and mobile phones is usually very short, which means that mobile phones need to frequently switch between different LEO satellites to ensure data transmission.

[0004] However, usually, when a mobile phone disconnects from the previous LEO satellite, it cannot promptly establish a connection with the next LEO satellite. In this case, it is necessary to use GEO satellites for assistance to achieve normal data transmission.

[0005] But if the mobile phone switches between two LEO satellites relatively quickly, that is, the communication connection time between the mobile phone and the GEO satellite is short, then if the data is overly compressed to meet the bandwidth requirements of the GEO satellite, it may affect the data quality. For example, when transmitting video data using a mobile phone, if the video data is overly compressed to meet the bandwidth requirements of the GEO satellite, it may affect the quality of the video data.

[0006] Publication number: CN119420410A, titled "Working Method, Equipment, Medium, and Program Product of a Satellite Communication and Remote Sensing Fusion System". The method includes: achieving time synchronization among components of the system through a high-precision clock and an integrated mission control unit; on the basis of time synchronization, the integrated mission control unit receives user remote sensing requirements sent by a space-ground power supply communication payload or a space-ground user communication payload and parses the user remote sensing requirements to obtain a parsing result; the integrated mission control unit issues an instruction to a remote sensing camera based on the parsing result; the remote sensing camera takes pictures according to the instruction and sends the remote sensing data to the integrated mission control unit; the integrated mission control unit determines the spectrum selection for data downlink according to the spectrum sensing information and, when meeting preset conditions, downlinks the remote sensing data based on the determined spectrum.

[0007] The publication number is CN119766313A, and the name is an unmanned aerial vehicle data transmission system and method based on low-earth orbit and high-earth orbit satellite integrated communication. In the basic communication link, obtain the task data type of the unmanned aerial vehicle, divide the task data type to obtain a data division result, obtain the communication characteristic data of the basic communication link, generate a basic connection coefficient based on the communication characteristic data, analyze the basic connection coefficient, and determine whether to generate a link adjustment instruction; receive the link adjustment instruction, and based on the basic connection coefficient, obtain the dynamic fusion training data of the unmanned aerial vehicle.

[0008] In view of the technical problem in the above-mentioned existing technology that if the mobile phone switches between two low-earth orbit satellites relatively quickly, that is, the communication connection time between the mobile phone and the high-earth orbit satellite is short, then if the data is overly compressed to meet the bandwidth requirements of the high-earth orbit satellite, the quality of the data may be affected, no effective solution has been proposed yet.

[0011] According to another aspect of the embodiments of the present disclosure, a storage medium is further provided. The storage medium includes a stored program, where, when the program runs, the method described in any one of the above is executed by a processor.

[0012] According to another aspect of the embodiments of the present disclosure, there is also provided a communication device based on the integration of low-earth orbit and high-earth orbit satellites, including: a satellite determination module, configured to determine a first low-earth orbit satellite, a high-earth orbit satellite, and a second low-earth orbit satellite for communication connection with a mobile phone; a first time determination module, configured to determine a first time corresponding to the first low-earth orbit satellite when the mobile phone disconnects from the first low-earth orbit satellite, where the first time is used to indicate the time when the mobile phone disconnects from the first low-earth orbit satellite; a second time determination module, configured to determine a second time corresponding to the second low-earth orbit satellite when the mobile phone has not yet established a communication connection with the second low-earth orbit satellite, where the second time is used to indicate the time required for the mobile phone to establish a communication connection with the second low-earth orbit satellite; a compression rate gradient value determination module, configured to determine a compression rate gradient value based on the first time, the second time, and the bandwidth value of the high-earth orbit satellite, where the compression rate gradient value is used to indicate the step value for changing the compression rate corresponding to the target data, and the target data is used to indicate the data transmitted by the mobile phone; and a gradient compression module, configured to determine a first compression rate corresponding to the current moment based on the compression rate gradient value when the mobile phone is in communication connection with the high-earth orbit satellite, and perform gradient compression on the target data.

[0013] According to another aspect of the embodiments of the present disclosure, there is also provided a communication device based on the integration of low-earth orbit and high-earth orbit satellites, including: a processor; and a memory, connected to the processor, configured to provide instructions for the processor to perform the following processing steps: determine a first low-earth orbit satellite, a high-earth orbit satellite, and a second low-earth orbit satellite for communication connection with a mobile phone; determine a first time corresponding to the first low-earth orbit satellite when the mobile phone disconnects from the first low-earth orbit satellite, where the first time is used to indicate the time when the mobile phone disconnects from the first low-earth orbit satellite; determine a second time corresponding to the second low-earth orbit satellite when the mobile phone has not yet established a communication connection with the second low-earth orbit satellite, where the second time is used to indicate the time required for the mobile phone to establish a communication connection with the second low-earth orbit satellite; determine a compression rate gradient value based on the first time, the second time, and the bandwidth value of the high-earth orbit satellite, where the compression rate gradient value is used to indicate the step value for changing the compression rate corresponding to the target data, and the target data is used to indicate the data transmitted by the mobile phone; and when the mobile phone is in communication connection with the high-earth orbit satellite, determine a first compression rate corresponding to the current moment based on the compression rate gradient value, and perform gradient compression on the target data.

[0014] The present application provides a communication method based on the integration of low-earth orbit (LEO) and geostationary orbit (GEO) satellites. First, the processor determines a first LEO satellite, a GEO satellite, and a second LEO satellite for communication connection with the mobile phone. Then, when the mobile phone disconnects from the first LEO satellite, the processor determines a first time corresponding to the first LEO satellite. Further, when the mobile phone has not yet established a communication connection with the second LEO satellite, the processor determines a second time corresponding to the second LEO satellite. Then, based on the first time, the second time, and the bandwidth value of the GEO satellite, the processor determines a compression rate gradient value. Finally, when the mobile phone is in communication connection with the GEO satellite, the processor determines a first compression rate corresponding to the current moment based on the compression rate gradient value and performs gradient compression on the target data.

[0015] As can be seen from the above, the processor of the mobile phone in this application does not directly compress the target data according to the original compression rate, but needs to pre-determine the compression rate gradient value according to the first time, the second time, and the bandwidth value of the GEO satellite. The compression rate gradient value is used to indicate the step value for changing the compression rate corresponding to the target data. And when the compression rate gradient value is determined, the first compression rate corresponding to the current moment is determined based on the compression rate gradient value, and gradient compression is performed on the target data. Therefore, compared with directly compressing the target data according to the original compression rate, the method provided by this application can not only meet the bandwidth requirements of the GEO satellite, but also not over-compress the data, thus ensuring the quality of the data.

[0016] Furthermore, it solves the technical problem in the prior art that if the mobile phone switches between two LEO satellites relatively quickly, that is, the communication connection time between the mobile phone and the GEO satellite is short, then if the data is over-compressed to meet the bandwidth requirements of the GEO satellite, it may affect the quality of the data.

[0026] Embodiment 1

[0027] According to this embodiment, an embodiment of a communication method based on the integration of low-earth orbit and geosynchronous orbit satellites is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0028] Figures 1A to 1C is a schematic diagram of the communication connection system of the mobile phone with the first low-earth orbit satellite, the geosynchronous orbit satellite, and the second low-earth orbit satellite respectively according to the embodiments of the present application. Refer to Figure 1AAs shown in the figure, the system includes: a first low-earth orbit satellite 110 and a mobile phone 30. And when the mobile phone 30 is within the communication coverage of the first low-earth orbit satellite 110, the mobile phone 30 also establishes a communication connection with the first low-earth orbit satellite 110, and uses the first low-earth orbit satellite 110 to transmit target data to other mobile terminals. The target data can be, for example, data corresponding to a video and / or data corresponding to a file, etc. In addition, it is worth noting that other mobile terminals are not shown in Figures 1A to 1C the figure.

[0029] After that, since the first low-earth orbit satellite 110 is constantly moving, at a certain moment, the mobile phone 30 is no longer within the communication coverage of the first low-earth orbit satellite 110 and disconnects from the first low-earth orbit satellite 110. Further, referring to Figure 1B the figure, when the mobile phone 30 is within the communication coverage of the geostationary satellite 20, the mobile phone 30 establishes a communication connection with the geostationary satellite 20, and uses the geostationary satellite 20 to transmit target data to other mobile terminals. In addition, due to the limited bandwidth resources of the geostationary satellite 20, when transmitting data using the geostationary satellite 20, the mobile phone 30 needs to use the compression rate gradient value to determine the first compression rate corresponding to the current moment, perform gradient compression on the target data, and then use the geostationary satellite 20 for data transmission.

[0030] Similarly, since the geostationary satellite 20 is constantly moving, at a certain moment, the mobile phone 30 is no longer within the communication coverage of the geostationary satellite 20 and disconnects from the geostationary satellite 20. Further, referring to Figure 1C the figure, when the mobile phone 30 is within the communication coverage of the second low-earth orbit satellite 120, the mobile phone 30 establishes a communication connection with the second low-earth orbit satellite 120, and uses the second low-earth orbit satellite 120 to transmit target data to other mobile terminals.

Referring to Figure 2A the figure, the first low-earth orbit satellite 110, the geostationary satellite 20, and the second low-earth orbit satellite 120 include an integrated electronic system, and the integrated electronic system includes: a processor, a memory, a bus management module, and a communication interface. The memory is connected to the processor, so that the processor can access the memory, read the program instructions stored in the memory, read data from the memory or write data to the memory. The bus management module is connected to the processor and is also connected to a bus such as a CAN bus. So that the processor can communicate with the on-board peripherals connected to the bus through the bus managed by the bus management module. In addition, the processor is also communicatively connected to devices such as a camera, a star sensor, a TT&C transponder, and a data transmission device. Those of ordinary skill in the art can understand, Figure 2AThe structure shown is only schematic and does not limit the structure of the above-mentioned electronic device.

Referring to Figure 2B , the mobile phone 30 may include one or more processors (the processor may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory for storing data, a transmission device for communication functions, and an input / output interface. The memory, the transmission device, and the input / output interface are connected to the processor through a bus. In addition, it may further include: a display, a keyboard, and a cursor control device connected to the input / output interface. Those of ordinary skill in the art can understand that Figure 2B the structure shown is only schematic and does not limit the structure of the above-mentioned electronic device. For example, the ground system may also include more or fewer components than those shown in Figure 2B or have a different configuration from that shown in Figure 2B .

[0033] It should be noted that Figure 2A and Figure 2B one or more processors and / or other data processing circuits shown in are generally referred to as "data processing circuits" herein.

It should be noted that Figure 2A and Figure 2B are only one example of a specific concrete instance and are intended to illustrate the types of components that may exist in the above device.

[0036] Under the above operating environment, according to the first aspect of this embodiment, a communication method based on the integration of low-earth orbit and high-earth orbit satellites is provided. This method is implemented by the Figures 1A to 1C system shown in. Figure 3 The flowchart of this method is shown. Referring to Figure 3 shown, this method includes:

[0037] S302: Determine the first low-earth orbit satellite, high-earth orbit satellite, and second low-earth orbit satellite for communicating with the mobile phone;

[0038] S304: In the case where the mobile phone disconnects the communication connection with the first low-earth orbit satellite, determine the first time corresponding to the first low-earth orbit satellite, where the first time is used to indicate the time when the mobile phone disconnects the communication connection with the first low-earth orbit satellite;

[0039] S306: In the case where the mobile phone has not yet established a communication connection with the second low-earth orbit satellite, determine the second time corresponding to the second low-earth orbit satellite, where the second time is used to indicate the time required for the mobile phone to establish a communication connection with the second low-earth orbit satellite;

[0040] S308: Based on the first time, the second time, and the bandwidth value of the high-earth orbit satellite, determine the compression rate gradient value, where the compression rate gradient value is used to indicate the step value for changing the compression rate corresponding to the target data, and the target data is used to indicate the data transmitted by the mobile phone; and

[0041] S310: In the case where the mobile phone is in communication connection with the high-earth orbit satellite, determine the first compression rate corresponding to the current moment based on the compression rate gradient value and perform gradient compression on the target data.

[0042] Specifically, first, the processor (in this embodiment, the processor is used to instruct the processor in the mobile phone 30) determines the first low-earth orbit satellite 110, the high-earth orbit satellite 20, and the second low-earth orbit satellite 120 for establishing a communication connection with the mobile phone 30 (S302). Among them, when the mobile phone 30 is within the communication coverage range of the first low-earth orbit satellite 110, the processor can determine the first low-earth orbit satellite 110 for establishing a communication connection with the mobile phone 30. And in this embodiment, when the mobile phone 30 determines the first low-earth orbit satellite 110, each low-earth orbit satellite and each high-earth orbit satellite can send position information and moving speed information to the first low-earth orbit satellite 110 in real time. And when the first low-earth orbit satellite 110 sends the received position information and moving speed information corresponding to each low-earth orbit satellite and each high-earth orbit satellite to the mobile phone 30, the processor can determine the high-earth orbit satellite 20 and the second low-earth orbit satellite 120 based on the position information and moving speed information corresponding to each low-earth orbit satellite and each high-earth orbit satellite.

[0043] Among them, since each high-earth orbit satellite 20, each first low-earth orbit satellite 110, and the second low-earth orbit satellite 120 have their respective corresponding ephemeris information, each high-earth orbit satellite 20, each first low-earth orbit satellite 110, and the second low-earth orbit satellite 120 can determine real-time position information and moving speed information based on the ephemeris information. And it is worth noting that each of the above-mentioned low-earth orbit satellites and high-earth orbit satellites in this embodiment can be, for example, all known high-earth orbit satellites and all low-earth orbit satellites currently.

[0044] For example, the processor determines the high-earth orbit satellite 20 that needs to establish a communication connection when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 based on the position information and moving speed information corresponding to each low-earth orbit satellite and each high-earth orbit satellite. Similarly, the processor determines the second low-earth orbit satellite 120 that needs to establish a communication connection when the mobile phone 30 disconnects from the high-earth orbit satellite 20 based on the position information and moving speed information corresponding to each low-earth orbit satellite and each high-earth orbit satellite.

[0045] Further, referring to Figures 1A to 1B as shown, when the first low-earth orbit satellite 110 moves continuously until the mobile phone 30 disconnects from the first low-earth orbit satellite 110, the mobile phone 30 establishes a communication connection with the high-earth orbit satellite 20. And when the mobile phone 30 disconnects from the first low-earth orbit satellite 110, the first time corresponding to the first low-earth orbit satellite is determined (S304). The first time is used to indicate the time when the mobile phone 30 disconnects from the first low-earth orbit satellite 110. Specifically, referring to Figure 1B as shown, when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 (that is, during the period when the mobile phone 30 establishes a communication connection with the high-earth orbit satellite 20), the processor determines the time when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 Moreover, as the first low-earth orbit satellite 110 keeps moving, the time when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 (i.e., the first time) will also change accordingly. Among them, the first time can be obtained, for example, by timing with a timer set on the first low-earth orbit satellite 110, and the first low-earth orbit satellite 110 will send data information corresponding to the first time to the mobile phone 30.

[0046] For example, at the moment , if the mobile phone 30 just disconnects from the first low-earth orbit satellite 110, then the time when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 ; at the moment , the time when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 ;...; at the moment , the time when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 .

[0047] Among them, as the first low-earth orbit satellite 110 keeps moving, the first time corresponding to the first low-earth orbit satellite 110 becomes larger and larger. That is, >... > > .

[0048] Similarly, as shown in Figures 1B to 1C , when the high-earth orbit satellite 20 keeps moving until the high-earth orbit satellite 20 establishes a communication connection with the second low-earth orbit satellite 120, the mobile phone 30 establishes a communication connection with the high-earth orbit satellite 20. And when the mobile phone 30 has not yet established a communication connection with the second low-earth orbit satellite 120, a second time corresponding to the second low-earth orbit satellite is determined (S306). The second time is used to indicate the time required for the mobile phone 30 to establish a communication connection with the second low-earth orbit satellite 120. Specifically, as shown in Figure 1B , when the mobile phone 30 has not yet established a communication connection with the second low-earth orbit satellite 120 (i.e., during the period when the mobile phone 30 establishes a communication connection with the high-earth orbit satellite 20), the processor determines the time required for the mobile phone 30 to establish a communication connection with the second low-earth orbit satellite 120. Moreover, as the second low-earth orbit satellite 120 keeps moving, the time required for the mobile phone 30 to establish a communication connection with the second low-earth orbit satellite 120 (i.e., the second time) will also change accordingly. Among them, the second time can be obtained, for example, by timing with a timer set on the second low-earth orbit satellite 120, and when the second low-earth orbit satellite 120 sends data information corresponding to the second time to the high-earth orbit satellite 20, the first low-earth orbit satellite 110 will send data information corresponding to the second time The corresponding data information is sent to the mobile phone 30. Of course, the mobile phone 30 can also determine the second time based on the received ephemeris information corresponding to the second low-earth orbit satellite 120 , which will not be elaborated here.

[0049] For example, at the moment , the time required for the mobile phone 30 to establish a communication connection with the second low-earth orbit satellite 120 ; at the moment , the time required for the mobile phone 30 to establish a communication connection with the second low-earth orbit satellite 120 ;...; at the moment , the mobile phone 30 and the second low-earth orbit satellite 120 are exactly within the communication coverage range of the second low-earth orbit satellite 120, and exactly establish a communication connection with the second low-earth orbit satellite 120. Then the time required for the mobile phone 30 to establish a communication connection with the second low-earth orbit satellite 120 .

[0050] Among them, as the second low-earth orbit satellite 120 moves continuously, the second time corresponding to the second low-earth orbit satellite 120 becomes smaller and smaller. That is, .

[0051] After that, the processor determines the compression rate gradient value based on the determined first time, second time, and the bandwidth value of the geostationary satellite (S308). The compression rate gradient value is used to indicate the step value for changing the compression rate corresponding to the target data. And the target data is used to indicate the data transmitted by the mobile phone. Specifically, since the bandwidth resources of the geostationary satellite 20 are limited during the period when the mobile phone 30 establishes a communication connection with the geostationary satellite 20, the processor needs to compress the target data first when transmitting the target data using the geostationary satellite 20. However, if the processor compresses the target data at the original compression rate, the quality of the target data may be poor due to excessive compression. Therefore, in this embodiment, the time when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 (i.e., the first time), the time required for the mobile phone 30 to establish a communication connection with the second low-earth orbit satellite 120 (i.e., the second time), and the bandwidth resources of the geostationary satellite 20 (i.e., the bandwidth value) are considered, and the step value for changing the compression rate corresponding to the target data is determined. The above content will be described in detail later, so it will not be elaborated here.

[0052] Finally, when the mobile phone 30 is communicatively connected to the high-orbit satellite 20, a first compression ratio corresponding to the current moment is determined based on the compression ratio gradient value, and gradient compression is performed on the target data (S310). Specifically, first, when the mobile phone 30 is communicatively connected to the high-orbit satellite 20, the processor determines a second compression ratio for compressing the target data at the previous moment. Then, the processor determines the first compression ratio for the mobile phone to compress the target data at the current moment based on the compression ratio gradient value and the second compression ratio. Further, it is determined whether the first compression ratio exceeds a preset compression ratio threshold, and when the first compression ratio exceeds the compression ratio threshold, the processor compresses the target data using the compression ratio threshold. When the first compression ratio does not exceed the compression ratio threshold, the processor compresses the target data using the first compression ratio. The above content will be described in detail later, so it will not be elaborated here.

[0053] As described in the background art, generally, when the mobile phone disconnects from the previous low-orbit satellite, it cannot promptly establish a connection with the next low-orbit satellite. Thus, in this case, it is necessary to utilize the high-orbit satellite for assistance to achieve normal data transmission.

[0054] However, if the mobile phone switches between two low-orbit satellites relatively quickly, that is, the communication connection time between the mobile phone and the high-orbit satellite is short, then if data is overly compressed to meet the bandwidth requirements of the high-orbit satellite, it may affect the data quality. For example, when transmitting video data using the mobile phone, if the video data is overly compressed to meet the bandwidth requirements of the high-orbit satellite, it may affect the quality of the video data.

[0055] In view of this, the present application provides a communication method based on the integration of low-orbit and high-orbit satellites. Moreover, the processor of the mobile phone in the present application does not directly compress the target data according to the original compression ratio, but rather needs to pre-determine the compression ratio gradient value according to the first time, the second time, and the bandwidth value of the high-orbit satellite. The compression ratio gradient value is used to indicate the step value for changing the compression ratio corresponding to the target data. And when the compression ratio gradient value is determined, a first compression ratio corresponding to the current moment is determined based on the compression ratio gradient value, and gradient compression is performed on the target data. Thus, compared with directly compressing the target data according to the original compression ratio, the method provided by the present application can not only meet the bandwidth requirements of the high-orbit satellite, but also not overly compress the data, thereby ensuring the data quality.

[0056] Furthermore, it solves the technical problem in the prior art that if the mobile phone switches between two low-orbit satellites relatively quickly, that is, the communication connection time between the mobile phone and the high-orbit satellite is short, then if data is overly compressed to meet the bandwidth requirements of the high-orbit satellite, it may affect the data quality.

[0057] Optionally, when the mobile phone is in communication connection with the high-orbit satellite, determining a first compression ratio corresponding to the current moment based on the compression ratio gradient value and performing gradient compression on the target data includes: when the mobile phone is in communication connection with the high-orbit satellite, determining a second compression ratio at which the mobile phone compressed the target data at the previous moment; determining a first compression ratio at which the mobile phone compresses the target data at the current moment based on the compression ratio gradient value and the second compression ratio; and compressing the target data using the first compression ratio.

[0058] Specifically, referring to Figure 1B as shown, when the mobile phone 30 is in communication connection with the high-orbit satellite 20, the processor determines the second compression ratio at which the mobile phone 30 compressed the target data at the previous moment. For example, the current moment is , and the processor determines that the second compression ratio at which the target data was compressed at time (i.e., the previous moment) is 100%. It should be noted that in this embodiment, since the mobile phone 30 and the high-orbit satellite 20 established a communication connection at time , time is the initial moment, and there is no previous moment for time .

[0059] After that, when the processor determines the compression ratio gradient value and the second compression ratio, it further determines a first compression ratio at which the mobile phone 30 compresses the target data at the current moment. For example, when the processor determines that the compression ratio gradient value is -5%, using the determined compression ratio gradient value of -5% and the previously determined second compression ratio of 100%, it determines that the first compression ratio at which the mobile phone 30 compresses the target data at the current moment is 95%.

[0060] Since the first time and the second time are constantly changing, the compression ratio gradient value will also change continuously. For example, when the processor determines that the compression ratio gradient value is 5%, using the determined compression ratio gradient value of 5% and the previously determined second compression ratio of 50%, it determines that the first compression ratio at which the mobile phone 30 compresses the target data at the current moment is 55%.

[0061] Finally, when the processor determines the first compression ratio, it can compress the target data using the determined compression ratio.

[0062] Optionally, it further includes: determining whether the first compression ratio exceeds a pre-set compression ratio threshold; when the first compression ratio exceeds the compression ratio threshold, compressing the target data using the compression ratio threshold; and when the first compression ratio does not exceed the compression ratio threshold, compressing the target data using the first compression ratio.

[0063] Specifically, referring to the above-mentioned content, it can be known that when determining the first compression ratio, the processor determines whether the first compression ratio exceeds a preset compression ratio threshold. For example, if the compression ratio threshold is 80%, the processor needs to determine whether the first compression ratio of 70% at which the mobile phone 30 compresses the target data at the current moment exceeds the compression ratio threshold of 80%. And when the first compression ratio exceeds the compression ratio threshold, the target data is compressed using the compression ratio threshold. And when the second compression ratio does not exceed the compression ratio threshold, the target data is compressed using the first compression ratio.

[0064] Optionally, the operation of determining the compression ratio gradient value based on the first time, the second time, and the bandwidth value of the high-orbit satellite includes: determining a corresponding variable based on the first time, the second time, and the bandwidth value of the high-orbit satellite; determining a compression ratio gradient threshold corresponding to the compression ratio gradient value, where the compression ratio gradient threshold is used to indicate the maximum value of the absolute value of the compression ratio gradient value at each moment; and determining the compression ratio gradient value based on the compression ratio gradient threshold and the variable.

[0065] Specifically, when i = 0, . Wherein, represents the compression ratio gradient value.

[0066] When i > 0, the processor first determines the bandwidth value of the high-orbit satellite 20 B i . Then, the processor determines the corresponding variable based on the first time, the second time, and the bandwidth value of the high-orbit satellite 20 B i . The formula for determining the variable is as follows:

[0067] (Formula 1)

[0068] Wherein, represents the first time, represents the second time, represents the bandwidth value of the high-orbit satellite.

[0069] The processor determines the compression ratio gradient threshold [- corresponding to the compression ratio gradient value M , M , where the compression ratio gradient threshold [- M , M is used to indicate the maximum value of the absolute value of the compression ratio gradient value at each moment M .

[0070] Thus, the processor can determine the compression ratio gradient value based on the compression ratio gradient threshold and the variable. The formula for calculating the compression ratio gradient value is as follows:

[0071] (Formula 2)

[0072] Wherein, M represents the absolute value of the compression rate gradient threshold. k is the compression rate gradient coefficient, which can be adjusted according to actual needs. If needs to change more violently, the value of k is larger.

[0073] Thus, the obtained through the above calculation formula changes more violently at a time point closer to ; it changes more gently when approaching the moment when the mobile phone 30 disconnects from the first low-earth orbit satellite 110 or the moment when the mobile phone 30 establishes a communication connection with the second low-earth orbit satellite 120.

[0074] Thus, according to the first aspect of this embodiment, the technical effect of meeting the bandwidth requirements of the geostationary satellite while ensuring the quality of data is achieved.

[0075] In addition, as shown in FIG. 1, according to the second aspect of this embodiment, a storage medium is provided. The storage medium includes a stored program, wherein when the program runs, the method described in any one of the above is executed by a processor.

[0076] Thus, according to this embodiment, the technical effect of meeting the bandwidth requirements of the geostationary satellite while ensuring the quality of data is achieved.
