[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In view of the above problems in the prior art, the present invention provides an application layer capability evaluation method for an Internet of Things satellite communication system. It should be noted that the execution subject of the method of the present invention may be other terminals other than the ground terminal, for example, it may be a host computer, or it may be an electronic device or a server. The present invention is not specifically limited here. The following embodiment is described with the host computer as the execution subject. Figure 1 FIG. 1 is a flow chart of an application layer capability evaluation method for an Internet of Things satellite communication system provided by the present invention, such as Figure 1 As shown, the method includes the following:

[0042] Step 110: Send an uplink instruction to a ground terminal in the Internet of Things satellite communication system; the uplink instruction is used to instruct the ground terminal to send uplink data to the on-orbit communication satellite in the Internet of Things satellite communication system when the on-orbit communication satellite passes by.

[0043] Specifically, the host computer sends a wake-up instruction to the ground terminal before the satellite passes through according to the satellite calendar, and the wake-up instruction is used to instruct the ground terminal to enter the working state. When the ground terminal enters the working state, the host computer can send an uplink instruction to the ground terminal in the Internet of Things satellite communication system. After receiving the uplink instruction, the ground terminal can send uplink data to the on-orbit communication satellite when the on-orbit communication satellite in the Internet of Things satellite communication system passes through. Among them, the type of uplink data can include data types such as short messages and voice, and the content of the uplink data can involve sensor collection data corresponding to Internet of Things application scenarios such as land, sea and low-altitude areas. In addition, when the on-orbit communication satellite receives the uplink data, it will also send the response data corresponding to the uplink data to the ground terminal. After receiving the response data, the ground terminal will delete the uplink data corresponding to the response data. To ensure the normal operation of the ground terminal, the ground terminal also includes at least the following auxiliary equipment: power supply facilities, lithium batteries, power consumption monitoring modules, antennas, cables and structural supports.

[0044] Optionally, it is also possible to pre-program in the ground terminal so that when an in-orbit communication satellite in the IoT satellite communication system passes by, uplink data is sent directly to the in-orbit communication satellite without sending an uplink command to the ground terminal.

[0045] Step 120: Acquire the downlink broadcast data sent by the on-orbit communication satellite.

[0046] Specifically, there may be multiple in-orbit communication satellites, and the in-orbit communication satellites may send downlink broadcast data to the ground terminal. The execution subject of the present invention may obtain the downlink broadcast data sent by the in-orbit communication satellite through the ground terminal, and after obtaining the downlink broadcast data, the downlink broadcast data may be stored through the data storage server. In addition, the execution subject of the present invention and the ground terminal may exchange data through a ground communication network, which includes but is not limited to the second generation mobile communication network (2nd Generation Mobile Communications Network, 2G), the third generation mobile communication network (3rd Generation Mobile Communications Network, 3G), the fourth generation mobile communication network (4th Generation Mobile Communications Network, 4G), the fifth generation mobile communication network (5th Generation Mobile Communications Network, 5G) and the narrow band Internet of Things (Narrow Band Internet of Things, NB-IoT).

[0047] Step 130: Determine an application layer capability evaluation result of the Internet of Things satellite communication system based on the downlink broadcast data, the uplink data and the monitoring data corresponding to the ground terminal.

[0048] Specifically, the application layer capability evaluation result of the Internet of Things satellite communication system can be determined based on the downlink broadcast data, the uplink data and the monitoring data corresponding to the ground terminal. The monitoring data may include monitoring data of the ground terminal and its surrounding environment.

[0049] In one embodiment, determining the application layer capability evaluation result of the Internet of Things satellite communication system based on the downlink broadcast data, the uplink data, and the monitoring data corresponding to the ground terminal includes:

[0050] Sending a monitoring instruction to the ground terminal; the monitoring instruction is used to trigger the ground terminal to send monitoring data; the monitoring data includes power consumption monitoring data and electromagnetic environment monitoring data;

[0051] The power consumption monitoring data and the electromagnetic environment monitoring data sent by the ground terminal are obtained, and the application layer capability evaluation result is determined based on the downlink broadcast data, the uplink data, the power consumption monitoring data and the electromagnetic environment monitoring data.

[0052] Specifically, a monitoring instruction can be sent to the ground terminal, and the monitoring instruction is used to trigger the ground terminal to send monitoring data, and the monitoring data includes power consumption monitoring data and electromagnetic environment monitoring data. That is, after receiving the monitoring instruction, the ground terminal will send the real-time monitored power consumption monitoring data and electromagnetic environment monitoring data to the execution subject of the present invention. Then, the power consumption monitoring data and electromagnetic environment monitoring data sent by the ground terminal can be obtained, and the power consumption monitoring data can characterize the power consumption of the ground terminal, and the electromagnetic environment monitoring data can characterize the electromagnetic conditions in the environment where the ground terminal is located. Further, the application layer capability evaluation result can be determined based on the downlink broadcast data, uplink data, power consumption monitoring data and electromagnetic environment monitoring data.

[0053] In the above embodiment, power consumption monitoring data and electromagnetic environment monitoring data sent by the ground terminal are obtained, and the application layer capability evaluation result is determined based on the downlink broadcast data, uplink data, power consumption monitoring data and electromagnetic environment monitoring data, so that the application layer capability evaluation of the Internet of Things satellite communication system is combined with the power consumption and electromagnetic environment corresponding to the ground terminal, thereby improving the accuracy of the application layer capability evaluation.

[0054] In one embodiment, determining the application layer capability evaluation result based on the downlink broadcast data, the uplink data, the power consumption monitoring data, and the electromagnetic environment monitoring data includes:

[0055] Determine the average satellite transit time corresponding to the on-orbit communication satellite based on the time corresponding to the first broadcast and the time corresponding to the last broadcast in the downlink broadcast data;

[0056] Determine the number of satellite transit arcs within a preset statistical period based on the downlink broadcast data;

[0057] The application layer capability evaluation result is determined based on the design upper limit of the uplink data within the preset statistical period, the average satellite transit time, the downlink broadcast data, the number of satellite transit arcs, the power consumption monitoring data and the electromagnetic environment monitoring data.

[0058] Specifically, the downlink broadcast data includes multiple broadcasts, and the average satellite transit time corresponding to the in-orbit communication satellite can be determined based on the time corresponding to the first broadcast and the time corresponding to the last broadcast in the downlink broadcast data. Furthermore, the number of satellite transit arcs within a preset statistical period can also be determined based on the downlink broadcast data. The number of satellite transit arcs represents the number of satellite transits within the statistical period, wherein the preset statistical period can be determined as needed, and the embodiment of the present invention does not make specific limitations here, for example, the preset statistical period can be seven days.

[0059] Furthermore, the design upper limit of the uplink data can be obtained through the ground terminal, and the application layer capability assessment result can be determined based on the design upper limit of the uplink data, the average satellite transit time, the downlink broadcast data, the number of satellite transit arcs, the preset statistical time period, the power consumption monitoring data and the electromagnetic environment monitoring data.

[0060] In the above embodiment, based on the time corresponding to the first broadcast and the time corresponding to the last broadcast in the downlink broadcast data, the average satellite transit time corresponding to the in-orbit communication satellite can be determined more accurately, and the number of satellite transit arcs within the preset statistical time period can be determined based on the downlink broadcast data. The application layer capability evaluation result is further determined based on the design upper limit of the uplink data, the average satellite transit time, the downlink broadcast data, the number of satellite transit arcs, the preset statistical time period, the power consumption monitoring data and the electromagnetic environment monitoring data, so that the application layer capability of the Internet of Things satellite communication system can be evaluated more accurately.

[0061] In one embodiment, the determining of the application layer capability evaluation result based on the design upper limit of the uplink data within the preset statistical period, the average satellite transit time, the downlink broadcast data, the number of satellite transit arcs, the power consumption monitoring data, and the electromagnetic environment monitoring data includes:

[0062] Determining a time revisit period of the on-orbit communication satellite based on the number of satellite transit arcs;

[0063] Determine the data uplink efficiency of the uplink data in the preset statistical period based on the design upper limit of the uplink data and the data volume of the uplink data successfully sent in the preset statistical period; the data volume of the uplink data successfully sent in the preset statistical period is determined based on the average transit time of the satellite;

[0064] The application layer capability evaluation result is determined based on the time revisit period, the data uplink efficiency, the downlink broadcast data, the power consumption monitoring data and the electromagnetic environment monitoring data.

[0065] Specifically, the time revisit period of the on-orbit communication satellite can be determined based on the number of satellite transit arcs.

[0066] Furthermore, the data volume of uplink data successfully sent within the preset statistical period can be divided by the design upper limit of the uplink data to obtain the data uplink efficiency of the uplink data within the preset statistical period. The data volume of uplink data successfully sent within the preset statistical period is determined based on the average transit time of the satellite. The application layer capability evaluation result can also be determined based on the time revisit period, data uplink efficiency, downlink broadcast data, power consumption monitoring data, and electromagnetic environment monitoring data.

[0067] In the above embodiment, the time revisit period of the on-orbit communication satellite is determined based on the number of satellite transit arcs, and then the data uplink efficiency of the uplink data in the preset statistical period is determined based on the design upper limit of the uplink data and the data volume of the uplink data successfully sent in the preset statistical period. The application layer capability evaluation result is further determined based on the time revisit period, data uplink efficiency, downlink broadcast data, power consumption monitoring data and electromagnetic environment monitoring data. The evaluation of the application layer capability of the Internet of Things satellite communication system by the present invention combines the data uplink efficiency of the uplink data and the time revisit period corresponding to the on-orbit communication satellite, and can obtain more accurate evaluation results.

[0068] In one embodiment, determining the application layer capability evaluation result based on the time revisit period, the data uplink efficiency, the downlink broadcast data, the power consumption monitoring data, and the electromagnetic environment monitoring data includes:

[0069] Determine the sleep power consumption, standby power consumption and signal transmission power consumption of the ground terminal based on the power consumption monitoring data;

[0070] Determine the environmental noise of the ground terminal based on the electromagnetic environment monitoring data, determine the transmission loss based on the equivalent isotropic radiated power corresponding to the onboard antenna of the on-orbit communication satellite, the signal-to-noise ratio and the signal strength of the downlink broadcast data, and determine the communication stability of the satellite-to-ground link corresponding to the Internet of Things satellite communication system based on the environmental noise and the transmission loss;

[0071] The time revisit period, the data uplink efficiency, the sleep power consumption, the standby power consumption, the signal transmission power consumption and the communication stability are determined as the application layer capability evaluation result.

[0072] Specifically, the ground terminal includes multiple modes such as sleep mode, standby mode and signal transmission mode. Therefore, the sleep power consumption, standby power consumption and signal transmission power consumption of the ground terminal can be determined based on the power consumption monitoring data. The above power consumption reflects the power consumption of the ground terminal. The environmental noise of the ground terminal can also be determined based on the electromagnetic environment monitoring data, and the transmission loss can be determined based on the equivalent isotropic radiated power corresponding to the onboard antenna of the in-orbit communication satellite, as well as the signal-to-noise ratio and signal strength of the downlink broadcast data. Then, the communication stability of the satellite-to-ground link corresponding to the Internet of Things satellite communication system can be determined based on the environmental noise and transmission loss. Finally, the time revisit period, data uplink efficiency, sleep power consumption, standby power consumption, signal transmission power consumption and communication stability can be determined as the application layer capability evaluation results. Among them, the equivalent isotropic radiated power corresponding to the onboard antenna of the in-orbit communication satellite is a predetermined fixed value.

[0073] In the above embodiment, the sleep power consumption, standby power consumption and signal transmission power consumption of the ground terminal are determined based on the power consumption monitoring data, and the environmental noise of the ground terminal is determined based on the electromagnetic environment monitoring data. The transmission loss is determined based on the equivalent isotropic radiated power corresponding to the onboard antenna of the in-orbit communication satellite, and the signal-to-noise ratio and signal strength of the downlink broadcast data. Then, the communication stability of the satellite-to-ground link corresponding to the Internet of Things satellite communication system is determined based on the environmental noise and transmission loss. Finally, the time revisit period, data uplink efficiency, sleep power consumption, standby power consumption, signal transmission power consumption and communication stability are determined as the application layer capability evaluation results. This embodiment takes into account the power consumption of the ground terminal and the impact of the environment on the communication stability, and improves the reliability of the application energy evaluation.
