[0034] Technical explanation: Intersatellite link refers to the communication link between satellites, which is used for data exchange and resource sharing.

[0035] The satellite-to-ground link refers to the communication link between the satellite and the ground station, through which the collected data (such as remote sensing data, scientific data, etc.) is transmitted to the ground station, or control instructions, user data, etc. are received from the ground station.

[0036] A time window is a certain period of time when a satellite passes through a specific communication arc in its orbit. During this period of time, the satellite is able to establish and maintain an effective communication link with a ground station or user. Each time window has a specific duration that depends on the orbital parameters of the satellite and the definition of the communication arc. The duration can vary from a few minutes to a few hours, depending on the orbital altitude of the satellite and the location of the ground station.

[0037] In view of the following problems existing in the prior art: there is a problem of slow response speed. The ground control center needs to receive the perception data of the satellite, analyze it and then send the command. There is a significant delay in the whole process, which affects the actual user experience. The method of satellite-ground collaborative communication and resource management proposed in the present invention obtains forward-looking data through intersatellite links, which can better cope with the dynamically changing communication environment; the satellite can dynamically allocate and adjust resources between different communication arcs, so that the satellite can quickly establish a high-quality satellite-ground connection when entering the next communication arc, ensuring that the satellite can achieve seamless transition between different communication arcs. The satellite can quickly establish a high-quality satellite-ground connection when entering a new communication arc, reducing communication interruptions, improving the continuity and stability of communication, and improving the user's communication experience.

[0038] In some embodiments of the present invention, Figure 1 As shown, the satellite-ground collaborative communication and resource management method of the present invention includes: Step 110: Divide the satellite orbit into multiple communication arcs according to the communicable elevation angle of the satellite to the earth; specifically, each communication arc corresponds to a time window of one or more ground areas covered by the satellite; it can be understood that the time window corresponding to each communication arc is a time period in which the satellite can communicate with a specific ground area, which helps the ground station to know the communication time of the satellite in advance, so as to facilitate effective communication planning and resource management.

[0039] Step 120: When determining that a satellite in the current communication arc is about to enter the next communication arc, a forward-looking data request is sent to the satellite in the next communication arc through an intersatellite link to obtain forward-looking data for entering the next communication arc; specifically, the forward-looking data in the next communication arc includes the electromagnetic environment, channel occupancy, user demand, and electromagnetic interference prediction information in the communication arc. It can be understood that data can be exchanged between satellites through intersatellite links while the satellites maintain communication without relying on ground stations.

[0040] Step 130: Based on the response of the satellite in the next communication arc, the forward-looking data in the next communication arc is obtained through the intersatellite link, and the satellite in the current communication arc processes the forward-looking data in the next communication arc to obtain the communication resources of the next communication arc, and the communication resources include the frequency resources, bandwidth, power resources, time resources and antenna resources in the next communication arc. It can be understood that the forward-looking data obtained from the next communication arc is processed by the edge computing capability of the satellite itself, so as to prepare for the resource allocation and configuration for the satellite in the current communication arc to enter the next communication arc, and ensure the continuity and effectiveness of the communication; wherein, the satellite in the current communication arc processes the forward-looking data in the next communication arc, and the data processing is processed by the edge computing capability of the satellite itself in the current communication arc.

[0041] Step 140: Pre-configure the satellites in the current communication arc segment based on the communication resources of the next communication arc segment to provide parameter support for the satellites in the current communication arc segment to enter the next communication arc segment for satellite-to-ground connection; specifically, the parameter support includes antenna pointing parameters, frequency matching parameters, communication protocol configuration parameters, and service mode switching parameters. It can be understood that, through the parameter support pre-configured by the satellites in the current communication arc segment, the satellites can quickly adjust and establish an effective satellite-to-ground connection when entering the next communication arc segment, thereby achieving efficient satellite-to-ground collaborative communication.

[0042] Step 150: When it is determined that a satellite in the previous communication arc is about to enter the current communication arc, a forward-looking data request provided by the satellite in the previous communication arc is received through an intersatellite link; specifically, the forward-looking data in the current communication arc includes the electromagnetic environment, channel occupancy, user demand and electromagnetic interference prediction information in the communication arc. It can be understood that data can be exchanged between satellites while the satellites maintain communication through the intersatellite link without relying on ground stations.

[0043] Step 160: Respond and send the forward-looking data in the current communication arc segment to the satellite in the previous communication arc segment through the intersatellite link, and the satellite in the previous communication arc segment performs data processing on the forward-looking data in the current communication arc segment to obtain the communication resources of the current communication arc segment; specifically, the satellite in the previous communication arc segment performs data processing on the forward-looking data in the current communication arc segment, and the data processing is performed by using the edge computing capability of the satellite in the previous communication arc segment itself; the communication resources after data processing include frequency resources, bandwidth, power resources, time resources and antenna resources. It can be understood that the forward-looking data obtained from the current communication arc segment is processed by the edge computing capability of the satellite itself, so as to prepare for resource allocation and configuration for the satellite in the previous communication arc segment to enter the current communication arc segment, thereby ensuring the continuity and effectiveness of communication.

[0044] Step 170: The satellite in the previous communication arc segment is pre-configured based on the communication resources of the current communication arc segment to provide parameter support for the satellite in the previous communication arc segment to enter the current communication arc segment for satellite-to-ground connection. Specifically, the parameter support includes: antenna pointing parameters, frequency matching parameters, communication protocol configuration parameters, and service mode switching parameters. It can be understood that, through the parameter support pre-configured by the satellite in the previous communication arc segment, the satellite can quickly adjust and establish an effective satellite-to-ground connection when entering the current communication arc segment, thereby realizing efficient satellite-to-ground collaborative communication.

[0045] In the above embodiment, in the technical solution of the present disclosure, the corresponding relationship between the communication resources and the parameter support is described as follows: Frequency resources correspond to frequency matching parameters: frequency resources refer to the frequency bands that can be used for communication, and the adjustment of frequency matching parameters ensures that the satellite can communicate effectively at the specified frequency. For example, if the frequency resources in a certain communication arc are relatively tight, by adjusting the frequency matching parameters, the existing frequency resources can be better utilized to avoid frequency conflicts and interference.

[0046] Bandwidth corresponds to communication protocol configuration parameters: Bandwidth refers to the amount of data that can be transmitted per unit time. Adjustment of communication protocol configuration parameters can optimize the efficiency of data transmission. For example, by selecting appropriate modulation and demodulation methods or compression algorithms, more data can be transmitted within limited bandwidth, thereby making more efficient use of bandwidth resources.

[0047] Power resources correspond to service mode switching parameters: Power resources refer to the energy required by satellites to transmit signals. Adjustment of service mode switching parameters can dynamically adjust the satellite's transmission power according to communication needs. For example, during high-load communication, it can switch to high-power mode to ensure signal strength; during low-load communication, it can switch to low-power mode to save energy.

[0048] Time resources and communication protocol configuration parameters: Time resources refer to the allocated time of communication channels. Adjustment of communication protocol configuration parameters can optimize the utilization of time resources. For example, through time division multiple access (TDMA) or frequency division multiple access (FDMA), services can be provided to more users within a limited time, thereby improving the utilization efficiency of time resources.

[0049] Antenna resources and antenna pointing parameters: Antenna resources refer to the antenna equipment on the satellite. Adjusting the antenna pointing parameters can ensure that the antenna is accurately aimed at the ground target, thereby maximizing the use of antenna resources. For example, by adjusting the antenna pointing, signal attenuation and interference can be avoided, ensuring the quality and stability of communication.

[0050] Through the above steps 110 to 170, in the technical solution of the present disclosure, in the proposed method of satellite-ground collaborative communication and resource management, forward-looking data is obtained through intersatellite links, so that the satellite in any communication arc segment obtains the forward-looking data in the next communication arc segment to be entered in advance, and then uses the edge computing capability of the satellite to process the forward-looking data, and obtains communication resources according to the processing results. The communication resources include frequency resources, bandwidth, power resources, time resources and antenna resources in the next communication arc segment, and then pre-configures the satellite based on the communication resources; so that when the satellite enters the next communication arc segment, it can quickly establish a high-quality satellite-ground connection and improve the user's communication experience. The satellite-ground collaborative and resource management method provided by the present invention obtains forward-looking data through intersatellite links, which can better cope with dynamically changing communication environments; satellites can dynamically allocate and adjust resources between different communication arc segments to enhance the flexibility and adaptability of the system; more satellites can be added to participate in communication without adding ground stations, thereby expanding the coverage and capacity of the system.

[0051] In the above embodiment, in the technical solution of the present disclosure, through step 120 and step 150, the satellite can obtain forward-looking data before entering a new communication arc segment, and these data include the electromagnetic environment, channel occupancy, user demand and electromagnetic interference prediction information of the next communication arc segment; using this information, the satellite in the current communication arc segment can pre-allocate and pre-configure the resources of the next communication arc segment, and optimize the use of frequency resources, bandwidth, power resources, time resources and antenna resources. Obtaining forward-looking data through intersatellite links can better cope with dynamically changing communication environments. Satellites can dynamically allocate and adjust resources between different communication arc segments, enhancing the flexibility and adaptability of the system.

[0052] In the above embodiment, in step 130 and step 160 of the technical solution of the present disclosure, the forward-looking data is processed through the edge computing capability of the satellite itself, so that the communication resources of the next communication arc can be obtained quickly and effectively, further improving the utilization efficiency of resources. Data processing through the edge computing capability of the satellite can reduce the burden on the ground station and reduce the operation and maintenance costs of the ground station.

[0053] In the above embodiment, the pre-configuration and parameter support in step 140 and step 170 of the technical solution of the present disclosure, including the adjustment of antenna pointing parameters, frequency matching parameters, communication protocol configuration parameters and service mode switching parameters, can ensure that the satellite can achieve seamless transition between different communication arcs. Through these pre-configurations, the satellite can quickly establish a high-quality satellite-to-ground connection when entering a new communication arc, reduce communication interruptions, and improve the continuity and stability of communication. By acquiring forward-looking data and sending response data through intersatellite links, satellites can achieve information sharing and collaborative work, further enhancing the reliability and stability of the communication system.

[0054] In the above embodiment, in step 120 and step 150 of the present disclosure, the collection and transmission method of the electromagnetic environment and the channel occupancy status is as follows: Figure 2 As shown, the collection and transmission methods of the electromagnetic environment and channel occupancy include: Step 211: Real-time collection of the electromagnetic environment and channel occupancy within the communication arc segment where the satellite is located; specifically, the electromagnetic wave detection equipment on the satellite is used to monitor the electromagnetic wave intensity, frequency distribution and interference sources in the surrounding environment in real time. These data can be collected by sensors and receivers on the satellite. Through the monitoring module of the satellite communication system, the usage of the current communication channel is obtained in real time, including the channel occupancy rate, available bandwidth, frequency usage, etc.; the above information can be collected through the log and real-time monitoring system of the satellite communication system.

[0055] Step 212: The electromagnetic environment and channel occupancy are transmitted forward to the satellite that is about to enter the above-mentioned communication arc segment through the intersatellite link. Specifically, the collected electromagnetic environment and channel occupancy data are packaged and encrypted, and transmitted to other satellites through the intersatellite link equipment on the satellite. The intersatellite link is a communication link between satellites that can achieve high-speed data transmission. The satellite that receives this data uses its own receiving equipment to decrypt and unpack the data, and then processes the data through its own edge computing capabilities to generate forward-looking data.

[0056] Through the above steps 211 to 212, in the technical solution of the present disclosure, the electromagnetic environment and channel occupancy are collected and transmitted in real time, which can provide forward-looking data for the satellite, ensuring that the satellite can adjust communication resources in time and optimize communication performance when entering a new communication arc. This embodiment improves the efficiency and quality of communication, enhances the flexibility and adaptability of the communication system, and can better cope with the dynamically changing communication environment.

[0057] In the above embodiment, in step 120 and step 150 of the present disclosure, the method for transmitting the prediction information of user demand and electromagnetic interference is as follows: Figure 3 As shown, the method for transmitting the prediction information of user demand and electromagnetic interference includes: Step 221: Collect and record user demand data and electromagnetic interference related data within the communication arc segment where the satellite is located; specifically, obtain the user's communication demand information through the user interface and monitoring module of the satellite communication system. These data can be recorded by user request, service type, data transmission rate, etc. The service types include voice communication, data transmission, video communication, navigation service, remote sensing service and emergency communication, etc. It can be understood that the electromagnetic wave detection equipment on the satellite is used to monitor the electromagnetic interference source, interference intensity and frequency range in the surrounding environment in real time, and these data can be collected and recorded by sensors and receivers on the satellite.

[0058] Step 222: The user demand data and electromagnetic interference related data in the communication arc of the satellite are transmitted to the ground station through the satellite-to-ground link; specifically, the collected user demand data and electromagnetic interference related data are packaged and encrypted, and transmitted to the ground station through the satellite-to-ground link equipment on the satellite. The ground station can receive these data through the receiving equipment.

[0059] Step 223: Filter and sort (i.e., denoise) the user demand data and electromagnetic interference related data based on the ground station to obtain the prediction information of user demand and electromagnetic interference; specifically, the ground station uses its powerful computing power to filter the user demand data and electromagnetic interference related data to remove noise and irrelevant information. Then, sort these data, analyze and predict them, and generate prediction information of user demand and electromagnetic interference. This information may include the trend of user demand, the changing law of electromagnetic interference, etc.

[0060] Step 224: Transmit the user demand and electromagnetic interference prediction information to the satellite in the communication arc segment in step 221 via the satellite-to-ground link; specifically, the generated user demand and electromagnetic interference prediction information is packaged and encrypted, and transmitted to the satellite via the satellite-to-ground link equipment of the ground station. The satellite can receive the prediction information via a receiving device.

[0061] Step 225: Transmit via intersatellite links to the satellite that is about to enter the communication arc in step 221. Specifically, the received user demand and electromagnetic interference prediction information are packaged and encrypted, and transmitted to other satellites via the intersatellite link equipment on the satellite. An intersatellite link is a communication link between satellites that can achieve high-speed data transmission. The satellite that receives this data uses its own receiving equipment to decrypt and unpack the data, and then processes the data through its own edge computing capabilities.

[0062] Through the above steps 221 to 225, in the technical solution of the present disclosure, the satellite can collect, transmit and process user demand data and electromagnetic interference related data, generate prediction information, and transmit this information to relevant satellites in real time. This method not only improves the utilization efficiency of communication resources, but also enhances the flexibility and adaptability of the communication system, and can better cope with the dynamically changing communication environment and user needs.
