[0053] Technical explanation:

[0054] Inter-satellite link refers to the communication link between satellites, used for data exchange and resource sharing.

[0055] The satellite-ground link refers to the communication link between the satellite and the ground station. Through the satellite-ground link, 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.

[0056] A time window is a certain time period in which a satellite passes a specific communication arc on its orbit. During this time, the satellite is able to establish and maintain an effective communication connection with a ground station or a user. Each time window has a specific duration, which depends on the orbital parameters of the satellite and the definition of the communication arc. The duration can vary from a few minutes to several hours, depending on the orbital height of the satellite and the location of the ground station.

[0057] In view of the problem in the prior art that the response speed is slow, the ground control center needs to receive the perception data of the satellite, analyze and then send a command, and 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 provided by the present application can better cope with the dynamically changing communication environment by obtaining forward-looking data through inter-satellite links; 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 seamless transition between different communication arcs, and quickly establishing a high-quality satellite-ground connection when entering a new communication arc, reducing communication interruption, improving communication continuity and stability, and improving user communication experience.

[0058] In some embodiments of the present application, as shown in Figure 1 The method of satellite-ground collaborative communication and resource management of the present application comprises:

[0059] Step 110: dividing the satellite orbit into multiple communication arcs according to the satellite's communicable elevation angle to the ground; 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 the time period during 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, facilitating effective communication planning and resource management.

[0060] Step 120: determining that the satellite in the current communication arc is about to enter the next communication arc, sending a forward-looking data request to the satellite in the next communication arc through an inter-satellite link to obtain forward-looking data for entering the next communication arc; specifically, the forward-looking data in the next communication arc includes prediction information of the electromagnetic environment, channel occupation, user demand and electromagnetic interference in the communication arc where it is located. It can be understood that data exchange can be carried out between satellites through the inter-satellite link while the satellites maintain communication, and does not need to rely on the ground station.

[0061] Step 130: based on the response of the satellite in the next communication arc segment, the forward-looking data in the next communication arc segment is obtained through the inter-satellite link, and the satellite in the current communication arc segment processes the forward-looking data in the next communication arc segment to obtain the communication resources of the next communication arc segment, including frequency resources, bandwidth, power resources, time resources and antenna resources in the next communication arc segment. It can be understood that the forward-looking data obtained from the next communication arc segment is processed by the edge computing capability of the satellite itself, so as to prepare for the resource allocation and configuration of the satellite in the current communication arc segment entering the next communication arc segment, and ensure the continuity and effectiveness of the communication; wherein the satellite in the current communication arc segment processes the forward-looking data in the next communication arc segment, and the data processing is processed by the edge computing capability of the satellite in the current communication arc segment.

[0062] Step 140: pre-configure the satellite in the current communication arc segment based on the communication resources of the next communication arc segment, to provide parameter support for the satellite in the current communication arc segment to enter the next communication arc segment for satellite-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 the parameter support pre-configured by the satellite in the current communication arc segment enables the satellite to quickly adjust and establish effective satellite-ground connection when entering the next communication arc segment, thereby realizing efficient satellite-ground cooperative communication.

[0063] Step 150: when the satellite in the previous communication arc segment is about to enter the current communication arc segment, receive the forward-looking data request provided by the satellite in the previous communication arc segment through the inter-satellite link; specifically, the forward-looking data in the current communication arc segment includes the prediction information of the electromagnetic environment, channel occupation, user demand and electromagnetic interference in the communication arc segment. It can be understood that data exchange can be carried out between satellites through the inter-satellite link while the satellite is maintaining communication, and does not need to rely on the ground station.

[0064] Step 160: in response to and through the inter-satellite link, the forward-looking data in the current communication arc segment is sent to the satellite in the previous communication arc segment, and the satellite in the previous communication arc segment processes 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 processes the forward-looking data in the current communication arc segment, and the data processing is processed by the edge computing capability of the satellite in the previous communication arc segment; 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 the resource allocation and configuration of the satellite in the previous communication arc segment entering the current communication arc segment, and ensure the continuity and effectiveness of the communication.

[0065] 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 entering the current communication arc segment to provide parameter support for the satellite in the previous communication arc segment entering the current communication arc segment. Specifically, the parameter support includes: antenna pointing parameters, frequency matching parameters, communication protocol configuration parameters, 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 effective satellite-ground connection when entering the current communication arc segment, thereby realizing efficient satellite-ground cooperative communication.

[0066] In the above embodiments, in the technical solution of the present disclosure, the correspondence between the communication resources and the parameter support is as follows:

[0067] The frequency resource corresponds to the frequency matching parameter: the frequency resource refers to the frequency band available for communication, and the adjustment of the frequency matching parameter ensures that the satellite can effectively communicate at the specified frequency. For example, if the frequency resource in a certain communication arc segment is relatively tight, by adjusting the frequency matching parameter, the existing frequency resource can be better utilized, and frequency conflict and interference can be avoided.

[0068] The bandwidth corresponds to the communication protocol configuration parameter: the bandwidth refers to the amount of data that can be transmitted per unit time, and the adjustment of the communication protocol configuration parameter 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 a limited bandwidth, thereby more effectively utilizing bandwidth resources.

[0069] The power resource corresponds to the service mode switching parameter: the power resource refers to the energy required for the satellite to transmit signals, and the adjustment of the service mode switching parameter can dynamically adjust the transmission power of the satellite according to the communication demand. For example, in high-load communication, it can be switched to a high-power mode to ensure signal strength; in low-load, it can be switched to a low-power mode to save energy.

[0070] The time resource corresponds to the communication protocol configuration parameter: the time resource refers to the allocation time of the communication channel, and the adjustment of the communication protocol configuration parameter can optimize the utilization of time resources. For example, through time division multiple access (TDMA) or frequency division multiple access (FDMA), etc., more users can be served within a limited time, thereby improving the utilization efficiency of time resources.

[0071] The antenna resource corresponds to the antenna pointing parameter: the antenna resource refers to the antenna equipment on the satellite, and adjusting the antenna pointing parameter can ensure that the antenna accurately points to the ground target, thereby maximizing the utilization of antenna resources. For example, by adjusting the antenna pointing, signal attenuation and interference can be avoided, ensuring the quality and stability of communication.

[0072] Through steps 110 to 170, in the technical solution of the present disclosure, the method for satellite-ground cooperative communication and resource management is proposed, the prospective data is acquired through the inter-satellite link, so that the satellite in any communication arc segment acquires the prospective data in the next communication arc segment in advance, then the edge computing capability of the satellite is used to process the prospective data, the communication resources including the frequency resources, bandwidth, power resources, time resources and antenna resources in the next communication arc segment are obtained according to the processing result, and then the satellite is pre-configured based on the communication resources; so that the satellite can quickly establish a high-quality satellite-ground connection when entering the next communication arc segment, and the communication experience of the user is improved. The method for satellite-ground cooperative communication and resource management provided by the present application can better cope with the dynamically changing communication environment by acquiring the prospective data through the inter-satellite link; the satellite can dynamically allocate and adjust the resources between different communication arc segments, thereby enhancing the flexibility and adaptability of the system; more satellites can be involved in communication without increasing the ground station, thereby expanding the coverage range and capacity of the system.

[0073] In the above embodiment, in the technical solution of the present disclosure, through steps 120 and 150, the satellite can acquire the prospective data before entering the new communication arc segment, which includes the prediction information of the electromagnetic environment, channel occupation, user demand and electromagnetic interference of the next communication arc segment; using these 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. By acquiring the prospective data through the inter-satellite link, the dynamically changing communication environment can be better coped with, and the satellite can dynamically allocate and adjust the resources between different communication arc segments, thereby enhancing the flexibility and adaptability of the system.

[0074] In the above embodiment, in steps 130 and 160 of the technical solution of the present disclosure, the prospective data is processed through the edge computing capability of the satellite itself, so that the communication resources of the next communication arc segment can be quickly and effectively obtained, and the utilization efficiency of the resources is further improved. Through the data processing by the edge computing capability of the satellite, the burden of the ground station can be reduced, and the operation and maintenance cost of the ground station can be reduced.

[0075] In the above embodiments, the pre-configuration and parameter support in steps 140 and 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 seamless transition of the satellite between different communication arcs. Through these pre-configurations, the satellite can quickly establish a high-quality satellite-ground connection when entering a new communication arc, reducing communication interruptions and improving the continuity and stability of communication. Through the acquisition of forward-looking data and the transmission of response data through inter-satellite links, information sharing and collaborative work between satellites can be achieved, further enhancing the reliability and stability of the communication system.

[0076] In the above embodiments, in steps 120 and 150 of the present disclosure, the collection and transmission method of the electromagnetic environment and channel occupation situation is as shown in Figure 2 The collection and transmission method of the electromagnetic environment and channel occupation situation includes:

[0077] Step 211: Real-time collection of electromagnetic environment and channel occupation situation in the communication arc where the satellite is located; Specifically, using the electromagnetic wave detection device on the satellite, the electromagnetic wave intensity, frequency distribution and interference source in the surrounding environment are monitored in real time. These data can be collected through sensors and receivers on the satellite. Through the monitoring module of the satellite communication system, the current communication channel usage is obtained in real time, including 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.

[0078] Step 212: Transmit the electromagnetic environment and channel occupation situation to the satellite that is about to enter the above communication arc through the inter-satellite link. Specifically, the collected electromagnetic environment and channel occupation situation data are packaged and encrypted, and transmitted to other satellites through the inter-satellite link device on the satellite. The inter-satellite link is a communication link between satellites, which can realize high-speed data transmission. The satellite receiving these data uses its own receiving device to decrypt and unpack the data, and then processes the data through its own edge computing capability to generate forward-looking data.

[0079] Through steps 211 to 212, in the technical solution of the present disclosure, real-time collection and transmission of electromagnetic environment and channel occupation situation can provide forward-looking data for the satellite, ensuring that the satellite can timely adjust communication resources when entering a new communication arc, optimizing communication performance. This embodiment improves the efficiency and quality of communication, enhances the flexibility and adaptability of the communication system, and can better cope with dynamically changing communication environments.

[0080] In the above embodiments, in steps 120 and 150 of the present disclosure, the transmission method of the predicted information of user demand and electromagnetic interference is as shown in Figure 3As shown, the user demand and electromagnetic interference prediction information transmission method includes:

[0081] Step 221: Collect and record user demand data and electromagnetic interference related data in the communication arc segment where the satellite is located; Specifically, through the user interface and monitoring module of the satellite communication system, the communication demand information of the user is obtained. These data can be recorded through user request, service type, data transmission rate, etc. The service type includes voice communication, data transmission, video communication, navigation service, remote sensing service and emergency communication, etc. It can be understood that the electromagnetic wave detection device 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 through the sensor and receiver on the satellite.

[0082] Step 222: Transmit the user demand data and electromagnetic interference related data in the communication arc segment where the satellite is located to the ground station through the satellite-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-ground link device on the satellite. The ground station can receive these data through the receiving device.

[0083] Step 223: Filter and arrange (i.e. denoising) the user demand data and electromagnetic interference related data based on the ground station to obtain the user demand and electromagnetic interference prediction information; Specifically, the ground station uses its powerful computing power to filter the user demand data and electromagnetic interference related data, remove noise and irrelevant information. Then, arrange these data, analyze and predict, generate user demand and electromagnetic interference prediction information. These information can include the trend of user demand, the change rule of electromagnetic interference, etc.

[0084] Step 224: Transmit the above-mentioned user demand and electromagnetic interference prediction information to the satellite in the communication arc segment in step 221 through the satellite-ground link; Specifically, the user demand and electromagnetic interference prediction information generated by processing is packaged and encrypted, and transmitted to the satellite through the satellite-ground link device of the ground station. The satellite can receive these prediction information through the receiving device.

[0085] Step 225: Transmit to the satellite that will enter the communication arc segment in step 221 through the inter-satellite link. Specifically, the received user demand and electromagnetic interference prediction information is packaged and encrypted, and transmitted to other satellites through the inter-satellite link device on the satellite. The inter-satellite link is a communication link between satellites, which can realize high-speed data transmission. The satellite receiving these data uses its own receiving device to decrypt and unpack the data, and then processes these data through its own edge computing capability.

[0086] Through steps 221-225, 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 the information to the relevant satellite 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 dynamically changing communication environments and user demands.
