DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0042] 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.

[0043] An embodiment of the present application provides a method for adjusting the transmission power of a satellite gateway station, 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 in the gateway station.

[0044] Reference Figure 1 A method for adjusting the transmission power of a satellite gateway includes: step S101, step S102, step S103 and step S104, wherein:

[0045] S101, obtaining the remaining data resource amount of the target satellite at the starting time point of the unit time period, and generating signal strength test data and data processing instructions.

[0046] In some embodiments, within a certain time period, the amount of rainfall is basically constant, that is, it can be understood that within a certain time period, the negative impact of rainfall on the uplink of the gateway station is basically the same. Therefore, a certain time period in which the rainfall is basically constant can be used as a unit time period, and the same power compensation is performed on the acquired user data during the time period from the starting time point of the unit time period to the end of the unit time period; wherein the uplink is a transmission link for data sent from the gateway station to the target satellite.

[0047] In some embodiments, the target satellite generally only performs data reception and forwarding, and does not further process the received data; in this case, the data received by the target satellite via the uplink and the data received by the user terminal or the gateway via the downlink will be affected by rainfall, that is, signal attenuation occurs; in addition, the time when the data passes through the uplink and the downlink is different, the degree of influence of rainfall is also different, and the degree of data attenuation caused by rainfall is also different. Therefore, the determination of rainfall attenuation during the one-way transmission of data can be considered, that is, the remaining data resource amount of the target satellite can be used to process the received user data and determine the rainfall attenuation of the uplink. At the beginning of the unit time period, it is determined whether the remaining data resource amount of the target satellite is sufficient to process the user data; wherein the downlink is the transmission link for data sent from the target satellite to the gateway.

[0048] In some implementations, in order to ensure that user data within a unit time period can be truly and effectively transmitted to the target satellite, it is possible to consider obtaining the remaining data resources of the target satellite before sending the user data within a unit time period to the target satellite, and generating signal strength test data and data processing instructions. The signal strength test data and data processing instructions are then used to determine the transmission power for sending user data within the unit time period.

[0049] S102: When the remaining data resource amount meets the preset data resource amount, the signal strength test data and the data processing instruction are sent to the target satellite.

[0050] In some embodiments, the electronic device compares the remaining data resource amount with the preset remaining data resource amount to determine whether the remaining data resource amount satisfies the subsequent response data processing instruction to process the signal strength test data; when it is determined that the remaining data resource amount satisfies the preset data resource amount, it indicates that the data resource amount of the target satellite at this time can also respond to the data processing instruction to process the signal strength test data while satisfying the data receiving and forwarding tasks and maintaining its own normal operation tasks. Then, the electronic device sends the signal strength test data and the data processing instruction to the target satellite, so that the target satellite affects the data processing instruction to process the signal strength test data.

[0051] S103: Determine signal transmission power compensation based on the acquired feedback data.

[0052] In some embodiments, the feedback data is data obtained after the target satellite processes the signal strength test data based on the data processing instructions.

[0053] After the electronic device sends the data processing instruction and the signal strength test data to the target satellite, the target satellite pre-processes the signal strength test data in response to the data processing instruction to obtain feedback data, wherein the feedback data includes the receiving power obtained by the target satellite after pre-processing the signal strength test data; then, the electronic device determines the signal transmission power compensation based on the feedback data; wherein the signal transmission power compensation represents the power compensation for the power attenuation caused by the influence of rainfall during the uplink transmission of the signal strength test data.

[0054] S104, determining an initial transmit power corresponding to user data received within a unit time period, and compensating the initial transmit power based on signal transmit power compensation to obtain a target transmit power corresponding to the user data.

[0055] In some embodiments, the initial transmission power is the transmission power at which the gateway transmits user data to the target satellite when there is no influence of rainfall.

[0056] After determining the signal transmission power compensation corresponding to the signal strength test data, the electronic device is ready to start transmitting to the received user; however, before that, it is necessary to determine the initial transmission power corresponding to the user data, wherein, since the position of the user terminal corresponding to each user data, the transmission power of the transmitted user data, and the distance from the gateway station may be different, the reception power when the gateway station receives the user data will also be different; therefore, after receiving the user data, the reception power of the gateway station receiving the user data cannot be used as a reference for the initial transmission power, and it is necessary to first determine the initial transmission power corresponding to each user data; then, the electronic device compensates the initial transmission power based on the determined signal transmission power compensation to obtain the target transmission power corresponding to the user data; subsequently, after receiving the user data within a unit time period, the electronic device sends the user data to the target satellite via an uplink based on the target transmission power, thereby reducing the distortion of the user data received by the target satellite due to rain attenuation, and improving the accuracy and authenticity of the user data.

[0057] In some embodiments, after obtaining the remaining data resource amount of the target satellite at the starting time point of a unit time period and generating signal strength test data and data processing instructions, it also includes: when the remaining data resource amount does not meet the preset data resource amount, generating inter-satellite data forwarding processing instructions; sending the signal strength test data, data processing instructions and inter-satellite data forwarding processing instructions to the target satellite, so that the target satellite responds to the inter-satellite data forwarding instructions, and sending the data processing instructions and the attenuated signal strength test data received by the target satellite to other satellites.

[0058] In some embodiments, the number of user terminals establishing communication services with each satellite is different, and the amount of user data received and forwarded is also different. In this case, the target satellite may be insufficient to respond to data processing instructions to process the signal strength test data. At this time, it is necessary to consider how to process the signal strength test data when the remaining data resources of the target satellite are insufficient.

[0059] It can be considered that after the target satellite receives the signal strength test data and data processing instructions, other satellites that meet the data resource requirements are used for processing. That is, when the electronic device determines that the remaining data resource amount does not meet the data resource amount, it generates an inter-satellite data forwarding processing instruction, and sends the signal strength test data, data processing instructions and inter-satellite data forwarding processing instructions to the target satellite, so that the target satellite responds to the inter-satellite data forwarding instruction and sends the data processing instruction and the attenuated signal strength test data received by the target satellite to other satellites; other satellites respond to the data processing instruction to process the signal strength test data and obtain feedback data generated by other satellites; subsequently, other satellites send the feedback data to the electronic device.

[0060] In some embodiments, before obtaining the remaining data resource amount of the target satellite at the starting time point of the unit time period, it also includes: constructing a rainfall prediction model, and substituting the acquired meteorological data into the rainfall prediction model for processing to determine multiple predicted rainfall data; wherein the multiple predicted rainfall data have a corresponding relationship with multiple preset time points within the preset time period; when there are at least two predicted rainfall data with an absolute difference less than the preset absolute difference among the multiple predicted rainfall data, the duration between the preset time points corresponding to the at least two predicted rainfall data is defined as the unit time period.

[0061] In some embodiments, rainfall is a random meteorological phenomenon; at different time points, whether it is raining in the area including the uplink and how much rainfall there is may be equal or different; in the case of rain, within a certain time period, the change between the rainfall per unit time is not large, that is, the influence of rain attenuation within a certain time period can be regarded as basically unchanged, therefore, when the user data received by the gateway within the certain time period is sent to the target satellite via the uplink, the same power compensation can be used to compensate the transmission power. Before obtaining the remaining data resource amount of the target satellite at the time point of the unit time period, a reasonable unit time period must be determined first; wherein, the determination of the unit time period can be predicted by monitoring the rainfall situation.

[0062] That is, the electronic device first constructs a rainfall prediction model, and substitutes the acquired meteorological data within a preset time period into the rainfall prediction model, and obtains a plurality of predicted rainfall data through processing by the rainfall prediction model, and the plurality of predicted rainfall data correspond one-to-one to a plurality of preset time points within the preset time period; then, the determined plurality of predicted rainfall data are compared, and the absolute difference between adjacent predicted rainfall data is determined, and when the absolute difference between at least two predicted rainfall data among the plurality of predicted rainfall data is less than the preset absolute difference, it indicates that the rainfall change between the preset time points corresponding to the at least two predicted rainfall data is very small, and the rain attenuation influence between the preset time points is substantially the same, and then the duration between the preset time points corresponding to the at least two predicted rainfall data can be defined as the unit time period.

[0063] In some embodiments, the rainfall prediction model can be a convolutional neural network model, a trajectory gated recursive unit model, a robot learning model, etc., which is not specifically limited in the embodiments of the present application.

[0064] In step S103, the feedback data includes the receiving power of the target satellite receiving the signal strength test data; based on the obtained feedback data, the signal transmission power compensation is determined, including: comparing the receiving power with the preset receiving power; when the receiving power is less than the preset receiving power, determining the absolute power difference between the receiving power and the preset receiving power, and determining the absolute power difference as the signal transmission power compensation.

[0065] In some embodiments, the electronic device preprocesses and analyzes the acquired feedback data to obtain the receiving power of the target satellite contained in the feedback data when receiving the signal strength test data; then, the electronic device compares the receiving power with the preset receiving power; when the receiving power is less than the preset receiving power, it indicates that the signal strength test data is greatly affected by rain attenuation during the uplink to the target satellite, and then the electronic device calculates the absolute difference between the receiving power and the preset receiving power to obtain the absolute power difference, and determines the absolute power difference as the signal transmission power compensation corresponding to the signal strength test data.

[0066] In some embodiments, after the absolute power difference is determined as the signal transmission power compensation, the signal transmission power compensation is determined based on the acquired feedback data, and the signal strength secondary verification data is generated, and the signal strength secondary verification data is sent to the target satellite based on the transmission power adjusted by the signal transmission power compensation; the secondary receiving power is determined based on the acquired second feedback data; wherein the secondary receiving power is the receiving power when the target satellite receives the signal strength secondary verification data; when the secondary receiving power is within a preset receiving power range, the signal transmission power compensation is defined as the final signal transmission power compensation.

[0067] In some embodiments, the electronic device will determine the signal transmission power compensation and adjust the transmission power of the signal strength test data to obtain the adjusted signal transmission power; then, the electronic device will generate the signal strength secondary verification data and transmit it to the target satellite via the uplink with the adjusted signal transmission power; the target satellite processes the signal strength secondary verification data to obtain second feedback data; then, the electronic device obtains the second feedback data and processes the second feedback data to obtain the secondary receiving power contained therein; then the electronic device compares the secondary receiving power with the preset receiving power; when the secondary receiving power is within the preset receiving power range, it indicates that the adjusted transmission power can reduce the impact of rain attenuation on the accuracy and authenticity of the data; then the electronic device uses the signal generation power compensation as the final signal transmission power compensation within a unit time period, thereby improving the accuracy of the determined signal transmission power compensation.

[0068] In step S104, the initial transmission power corresponding to the user data received within the unit time period is determined, including: obtaining the user transmission power and the user reception power corresponding to the user data received within the unit time period; based on the user transmission power and the user reception power, determining the data power attenuation in the process of sending the user data to the gateway; when the data power attenuation is less than the preset power attenuation, determining the initial transmission power corresponding to the user data.

[0069] In some embodiments, the user transmission power is the power when the user data is transmitted by the user terminal; the user reception power is the reception power when the gateway receives the user data.

[0070] There is a situation where user data distortion occurs when the gateway receiving station receives user data sent by the user terminal. In the case of distorted user data, no matter how much transmission power the gateway uses to send the user data to the target satellite for transmission, the user data will be distorted; therefore, when determining the initial transmission power corresponding to the user data, it is necessary to determine whether the user data received by the gateway is distorted; that is, when the electronic device obtains the user data within a unit time period, it obtains the user transmission power and user reception power corresponding to the data; then the absolute difference between the user transmission power and the user reception power is calculated to obtain the data power attenuation in the process of sending the user data to the gateway; then the electronic device compares the data power attenuation with the preset power attenuation; when it is judged that the data power attenuation is less than the preset power attenuation, the initial transmission power corresponding to the user data is determined.

[0071] In some embodiments, after determining the data power attenuation amount in the process of sending user data to the signal gateway, determining the initial transmission power corresponding to the user data received within a unit time period also includes: when the data power attenuation amount is not less than the preset power attenuation amount, it indicates that the user data received by the signal gateway at this time may be distorted, and therefore it is necessary to determine the authenticity of the user data, that is, the electronic device generates user data authenticity verification information, and sends the user data authenticity verification information to the user terminal corresponding to the data power attenuation amount; when the authenticity information obtained by the electronic device is that the user data is not distorted, determining the initial transmission power corresponding to the user data; wherein the authenticity information is information generated by the user terminal based on the user data authenticity verification information.
