Description

Technical Field

[0001] The present disclosure relates to the field of satellite communications, and more specifically to a ground access method, device, equipment, medium and program product for satellite communications. Background Art

[0002] Today's society has increasingly higher requirements for mobile communications, not only to solve the signal coverage problem, but also to improve user experience. Due to the advantages of satellite communication, such as wide local coverage, long communication distance, flexible station deployment, and fast opening, the existing satellite communication ground equipment, after receiving the satellite wireless signal, converts it into a wireless signal for the end users around the device, or connects to other communication equipment to transfer the signal, generally based on the L-band and S-band, with limited uplink and downlink frequency bandwidth, resulting in very low uplink and downlink data throughput, high channel usage fees, and expensive equipment. It is limited to the field of emergency communications and industry-specific network applications, and can no longer meet the growing demand for satellite communications.

[0003] The disadvantages of traditional satellite ground receiving devices currently on the market are: (1) single function. In areas without satellite signal coverage, the device loses its communication purpose; (2) high equipment cost. After receiving the satellite signal, other devices are required to convert it into a wireless signal for use by terminal users around the device. The terminal access method is single and the signal coverage range is small, and remote maintenance is not possible. From the perspective of frequency of use, the cost of the entire device is very high; (3) once the wired link is disconnected, the operating status of the remote device cannot be obtained. After the device is down, it is impossible to perform remote operation and cannot resume normal operation. Technical personnel must be sent to the location of the device or the customer must bring the device to the manufacturer for repair. There is a lack of maintenance methods, remote maintenance is not possible, the operation risk is high, and the operation and maintenance cost is very high; (4) external connection with other communication equipment such as small base station equipment to forward signals requires multiple hardware devices to be interconnected or multiple boards to be cascaded. The hardware integration is low, the power consumption is high, the device connection is complex, and it is not easy to operate. The reliability of the device is poor, it is difficult to use, and it is not user-friendly. Summary of the invention

[0041] Figure 1 The application scenario diagram of ground access of satellite communication according to an embodiment of the present disclosure is schematically shown.

[0042] like Figure 1 As shown, the application scenario 100 according to this embodiment may include signal access terminal device scenarios such as high-throughput satellite communication access, ground cellular network access, 5G small base station access and WiFi access. The first network 104 is used to provide a medium for a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103 and the converged communication service device 105. The second network 106 is used to provide a medium for a communication link between the satellite 107 and the converged communication service device 105, so that the converged communication service device 105 can access the Ka-band satellite signal and / or the ground coverage signal, and provide the first terminal device 101, the second terminal device 102, and the third terminal device 103 with the network services required by the user, wherein the first network 104 and the second network 106 may include various connection types, such as wired, wireless communication links, satellite links or optical fiber cables, etc.

[0043] The user can use the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the converged communication service device 105 through the first network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only for example).

[0044] The first terminal device 101, the second terminal device 102, and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0045] The converged communication service device 105 can be a multi-mode converged communication system that supports multiple wireless access technologies such as high-throughput satellite communication, Sub6G small base stations, 4G / 5G terminals, WiFi, GPS, etc. The converged communication service device 105 can be a server that provides various services, such as a background management server (only as an example) that provides support for websites browsed by users using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server can analyze and process the received user request and other data, and feed back the processing results (such as web pages, information, or data obtained or generated according to the user request) to the terminal device.

[0046] It should be noted that the ground access method for satellite communication provided in the embodiment of the present disclosure can generally be executed by the converged communication service device 105. Accordingly, the ground access device for satellite communication provided in the embodiment of the present disclosure can generally be set in the converged communication service device 105. The ground access method for satellite communication provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the converged communication service device 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the converged communication service device 105. Accordingly, the ground access device for satellite communication provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the converged communication service device 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the converged communication service device 105.

[0047] It should be understood that Figure 1 The number of terminal devices, networks, satellites, and converged communication service devices in the embodiment is only illustrative. Any number of terminal devices, networks, satellites, and converged communication service devices may be provided according to implementation requirements.

[0048] The following will be based on Figure 1 The scene described by Figure 2~Figure 14 The ground access method for satellite communication of the disclosed embodiment is described in detail.

[0049] Figure 2 The flowchart of the ground access method of satellite communication according to an embodiment of the present disclosure is schematically shown.

[0050] like Figure 2 As shown, the ground access method of satellite communication of this embodiment includes operation S210 to operation S240, and the ground access method is applied to a multi-mode fusion communication system. Figure 3 The schematic diagram of the architecture of the multi-mode fusion communication system according to the embodiment of the present disclosure is shown as follows: Figure 3 As shown, it can simultaneously support multiple wireless access technologies such as high-throughput satellite communications, Sub6G small base stations, 4G / 5G terminals, WiFi, GPS, etc.

[0051] In operation S210, based on the user's networking requirements, a first wireless communication signal is received through a specific antenna; wherein the first wireless communication signal includes a Ka-band satellite signal and / or a ground coverage signal.

[0052] The first wireless communication signal is a signal received by the multi-mode fusion communication system through the antenna. The user's networking needs may change according to the actual usage scenario. Therefore, the receiving end of the system can not only receive Ka-band satellite signals, but also ground coverage signals. Both signals can be received separately or simultaneously. At the output end of the system, you can choose to start the Sub6G small base station function or the WiFi function independently according to the actual needs of the user, or start the Sub6G small base station function and the WiFi function at the same time. Users can adopt flexible access methods. User terminal devices can use 5G signal access to make voice calls or access the Internet through WiFi signals, or they can switch according to user needs. The diversity of access methods ensures that both satellite access and operator network access can meet communication needs. This fusion communication system is widely used, has strong anti-interference ability, flexible usage, diverse communication methods, and stable data rates, which can meet the needs of various users to the greatest extent.

[0053] It should be noted that the Ka-band satellite signal is a satellite communication signal transmitted based on the Ka-band frequency range. The Ka-band usually refers to the microwave frequency band of 30-300 GHz. The signal has a higher frequency and can carry more data information. The ground coverage signal is the operator network signal, which is a wireless or wired signal used to realize various communication functions, such as 2G, 3G, 4G, and 5G signals, transmitted by the communication operator through the communication network infrastructure it builds and operates. The Sub6G small base station function refers to the radiation of the Sub6G small base station signal. The Sub6G small base station signal is a wireless communication signal emitted by a small base station working in the Sub6G frequency band (usually refers to a frequency band below 6 GHz). The WiFi function refers to the radiation of the wireless signal, which is a wireless communication signal based on Wireless Fidelity (WiFi) technology.

[0054] In operation S220, the Ka-band satellite signal is processed using the first physical layer of the preset chip to obtain first network data, and / or the ground coverage signal is processed using the mobile communication module to obtain second network data.

[0055] According to an embodiment of the present disclosure, the preset chip is a PC802 single chip.

[0056] In the digital signal processing process of the multi-mode converged communication system, the PC802 single chip is used. The PC802 baseband SoC chip is an integrated module of satellite terminal and small base station based on the domestic baseband chip PC802. The chip contains 3 high-performance DSPs with a main frequency of 800MHz and support 1280bit bit width vector cloud computing and 32 RISC-V scalar processors with a main frequency of 1GHz. The rich HWA hardware accelerator supports fast Fourier transform and discrete Fourier transform (FFT, DFT), channel equalization, channel coding (supporting 4G Turbo codec, 5G LDPC and Polar codec, HARQ) and other functions, supports digital front end (DFE), and has high-performance, low-power and programmable capabilities. At the same time, the PC802 chip is equipped with a rich set of peripheral interfaces, including JESD204B interface supporting 4 lanes, each lane rate can reach 9.8304Gbps; eCPRI interface rate supports 10G / 25Gbps; Ethernet interface 10G / 25G is configurable; PCIe interface supports 4-channel PCIe4.0, with a maximum transmission bandwidth of 4GB / s; LPDDR4 interface supports 2666 / 3200MHz; supports IEEE1588v2 and GNSS interfaces. The PC802 chip can simultaneously support different combinations of high-speed serial port data rates with bandwidths of no more than 40MHz per channel for 16 channels, 100MHz per channel for 8 channels, 200MHz per channel for 4 channels, or 400MHz per channel for 2 channels. The average power consumption of the chip is less than 6W, and it supports low power consumption mode.

[0057] The integrated satellite terminal and small base station module based on PC802 innovatively realizes the ability to process multi-cell digital signals under multiple standards on a single chip. That is, on the PC802 single chip, part of the physical layer resources (first physical layer) are used for Ka-band CPE terminal signal processing, and the other part of the physical layer resources (second physical layer) are used for Sub6G band small base station signal processing. Figure 4 The system structure diagram of the PC802 single chip according to the embodiment of the present disclosure is schematically shown. Figure 4 As shown in the figure, the detailed system architecture of the satellite terminal and small base station integrated module based on PC802 can simultaneously process the high-throughput digital signals of broadband satellite terminals and the baseband digital signals of 4 / 5G small base stations through the digital signal processing of the PC802 single chip. This solution effectively reduces the complexity of hardware design and the size of the board, reduces the power consumption and cost of the whole machine, and realizes multi-mode integration.

[0058] The integrated satellite terminal and small base station module based on PC802 chip can realize the ability to process multi-cell signals under multiple standards on a single chip. On the PC802 single chip, part of the physical layer (first physical layer) resources are used for Ka-band CPE terminal signal processing, and the other part of the physical layer resources (second physical layer) are used for Sub6G band small base station signal processing. It effectively reduces the complexity of hardware design and the size of the board, reduces the power consumption and cost of the whole machine, and realizes multi-mode integration.

[0059] It is worth noting that the first network data is information data obtained by processing Ka-band satellite signals through the PC802 single chip. The second network data is information data obtained by processing ground coverage signals through a mobile communication module (such as a 4 / 5G terminal module). Based on the user's networking needs and the actual network environment, if only the Ka-band satellite signal is received, only the first network data is generated; if only the ground coverage signal is received, only the second network data is generated; that is, if both the Ka-band satellite signal and the ground coverage signal are received, the first network data and the second network data are generated.

[0060] In operation S230, adaptive network routing selection is performed on the network multi-dimensional aggregated data using a routing decision model to obtain an optimal data transmission path; wherein the network multi-dimensional aggregated data includes the first network data and / or the second network data.

[0061] The Ka-band satellite communication terminal module and 4 / 5G terminal module in the multi-mode fusion communication system can be used to access the wireless network to obtain multi-dimensional aggregated data of the relevant network, and use dynamic scheduling combined with an adaptive network selection algorithm to achieve intelligent routing selection of data channels.

[0062] A set of adaptive network selection algorithms is built using machine deep learning technology to train the routing decision model to predict and determine the optimal data transmission path. The input of the routing decision model is the multi-dimensional network aggregation data, which includes not only the first network data and / or the second network data, but also network environment dimension data (such as signal strength, signal-to-noise ratio, channel connectivity, channel rate, network delay, network stability, network load, ambient temperature, etc.), user behavior dimension data (the amount of data that users query, access, and use), and cost dimension data (users' habits of using devices, network traffic costs) and other related data that help the model predict the path. These input network multi-dimensional aggregation data are used to train the routing model so that it can dynamically adjust the routing strategy according to changes in the network environment and user habits. The output of the routing decision model is that the trained routing model can predict and determine the optimal data transmission path that meets user behavior, and automatically adjust the rate ratio of each communication channel to ensure that the signal quality of each channel remains at a high level.

[0063] Through these multi-dimensional aggregated data of the network, the status of each network can be evaluated, and the optimal data transmission path that meets user behavior can be predicted and determined. Using the routing decision model for adaptive network selection can optimize the route in real time while ensuring fast response, and realize efficient data flow switching methods. By monitoring the network load, a network structure containing multiple computing paths is built, and the data transmission path is automatically adjusted according to user needs or input characteristics. The rate ratio of each communication channel is automatically adjusted to avoid network congestion, improve network throughput and reliability, and ensure user experience.

[0064] Dynamic scheduling can automatically adjust the rate ratio of each communication channel. When the signal quality of a certain channel is poor, the data rate of other channels can be increased to ensure that the signal quality of each channel remains at a high level, with high signal-to-noise ratio, low power consumption, and high data rate output. For example, when the satellite signal is good, the satellite high-throughput and high-bandwidth channels are used first; when in an urban area and the ground cellular network signal is strong, it automatically switches to the ground cellular network to save costs. When users transmit high-priority data, the available network channels are increased to increase the data bandwidth to ensure service quality; when users transmit low-priority data, the available bandwidth is appropriately reduced to balance the overall performance. The intelligent scheduling framework allows for rapid response to network changes and flexible adjustment of resource allocation strategies to meet diverse service needs.

[0065] In operation S240, based on the optimal data transmission path, the resource allocation ratio of the communication channel in different modes is dynamically scheduled, and the first network data and / or the second network data is converted into a second wireless communication signal to access the second wireless communication signal to provide communication services to the user.

[0066] In the multi-mode converged communication system, the second wireless communication signal (the transmission signal after system conversion, such as the communication signal containing communication data, business data and other data) can be transmitted through the Sub6G small base station module and the WiFi module. The second wireless communication signal includes a wireless signal and / or a Sub6G small base station signal, which can be switched and selected according to the user's networking needs. The Sub6G small base station module can be used alone to radiate the Sub6G small base station signal to meet the user's voice call, emergency communication and other needs. The WiFi module (wireless module) can also be used alone to radiate the wireless signal to meet the user's networking communication and entertainment needs. The Sub6G small base station module and the WiFi module can also be turned on at the same time to meet the various needs of multiple users, greatly improve the processing capacity of data communication, and reduce hardware complexity and unit traffic cost.

[0067] Dynamically scheduling the resource allocation ratio (such as rate ratio) of communication channels in different modes can automatically adjust the rate ratio of each communication channel. When the signal quality of a certain channel is poor, the data rate of other channels can be increased, thereby ensuring that the signal quality of each channel remains at a high level, with high signal-to-noise ratio, low power consumption, and high data rate output. Even when network conditions change and when switching between different network modes and data channels occurs, the user experience can be guaranteed to be uninterrupted, and efficient data stream switching can be achieved. This dynamic scheduling method is especially important for applications with strong mobility, and can effectively avoid service interruptions caused by signal loss.

[0068] According to the actual user networking needs, communication channels of different modes will be opened, and the communication channels under different modes include the first mode communication channel, the second mode communication channel, the third mode communication channel, the fourth mode communication channel, and the fifth mode communication channel.

[0069] The first mode communication channel, through a multi-mode fusion communication system, uses the Ka-band CPE terminal module to receive high-throughput satellite high-bandwidth data streams, converts them into wireless signals (WiFi signals) and provides them to users. It can solve the demand for broadband Internet access in areas without ground base station signal coverage, and can be applied to emergency communications, aerospace, high-speed rail, outdoor travel and office, transportation and logistics, special applications and other scenarios. Figure 5 The data flow diagram of the first mode communication channel according to the embodiment of the present disclosure is schematically shown. As shown in Figure 5, the Ka-band satellite signal is received by the phased array antenna, converted into a baseband signal by the intermediate frequency module and transmitted to the baseband chip PC802. The baseband chip transmits the processed physical layer data to the upper-layer NPU protocol stack through the PCIe interface. Part of the network data processed by the protocol stack will be transmitted to the fusion platform, and other control service data (such as control information and service data) will be transmitted to the wireless module (WiFi module), and the multi-frequency antenna of the wireless module will send a signal to provide it to the user for access.

[0070] The second mode communication channel uses a multi-mode fusion communication system to receive high-throughput satellite high-bandwidth data streams using the Ka-band CPE terminal module, converting them into Sub6G small base station signals to radiate the surrounding areas. At the same time, it can be equipped with a high-power amplifier to achieve long-distance coverage of more than 30 kilometers. It is suitable for a variety of scenarios such as emergency communications, signal blind spots, and special applications. Figure 6The data flow diagram of the second mode communication channel according to the embodiment of the present disclosure is schematically shown. As shown in Figure 6, the device receives the Ka-band satellite signal through the phased array antenna, converts it into a baseband signal through the intermediate frequency module and transmits it to the baseband chip PC802. The baseband chip transmits the processed physical layer data to the upper protocol stack through the PCIe interface. Part of the network data processed by the protocol stack will be passed to the fusion platform, and other control information and business data will be passed to the Sub6G small base station module. Here, the physical layer of the Ka-band satellite terminal module and the physical layer of the Sub6G small base station module can be processed by the same baseband chip PC802, and the RF antenna of the base station module sends a signal to provide it to the user for access.

[0071] The third mode communication channel uses a multi-mode integrated communication system. The 4 / 5G terminal module obtains the ground operator's public network coverage signal (ground coverage signal), converts it into a Sub6G small base station signal and provides it to users for access. In areas where some operators' public network signal coverage is incomplete or unstable, it can play the role of wireless signal relay. It is more suitable for networking demand scenarios in special environments such as airplanes and high-speed railways, as well as indoor signal coverage in factories and buildings. Figure 7 The schematic diagram of the data flow of the third mode communication channel according to the embodiment of the present disclosure is shown schematically. As shown in FIG7, in areas without satellite signal coverage, it is possible to switch to the operator 4 / 5G network mode and receive the operator wireless network signal through the mobile communication antenna (4 / 5G antenna). As shown in the schematic diagram, the mobile communication module includes a 4 / 5G module, and three 4 / 5G terminal modules can be used. Each module can be connected to a different operator network to increase the data rate. It is also possible to add several 4 / 5G terminal modules, and multiple modules can be connected to the network together to increase the total data rate. The specific number of 4 / 5G terminal modules needs to be considered comprehensively based on the volume, power consumption and cost of the actual equipment. The 4 / 5G terminal module transmits part of the processed network data to the fusion platform, and transmits other control information and business data to the Sub6G small base station module based on the PC802 chip, and the RF antenna of the base station module sends a signal to provide it to the user for access.

[0072] The fourth mode communication channel uses a multi-mode integrated communication system. The 4 / 5G terminal module obtains the public network coverage signal (ground coverage signal) of the ground operator and converts it into a wireless signal for ground users. This effectively solves the networking needs of wireless devices and is more suitable for outdoor equipment networking scenarios such as industrial Internet, agricultural automation, outdoor travel and office. Figure 8The schematic diagram of the data flow of the fourth mode communication channel according to the embodiment of the present disclosure is shown schematically. As shown in FIG8, in areas without satellite signal coverage, it is possible to switch to the operator 4 / 5G network mode and receive the operator wireless network signal through the 4 / 5G antenna. As shown in the schematic diagram, three 4 / 5G terminal modules are used, and each module can be connected to a different operator network to increase the data rate. Several more 4 / 5G terminal modules can also be added, and multiple modules can be connected to the network together to increase the total data rate. The specific number of 4 / 5G terminal modules needs to be considered comprehensively based on the volume, power consumption, and cost of the actual equipment. The 4 / 5G terminal module transmits part of the processed network data to the fusion platform, and other control information and business data are transmitted to the WiFi module. The multi-frequency antenna of the WiFi module sends wireless signals for user access.

[0073] The fifth mode communication channel uses a multi-mode integrated communication system. The Ka-band high-throughput CPE terminal module receives satellite signals, and uses the 4 / 5G terminal module to obtain the ground operator's public network coverage signal (ground coverage signal), which is converted into Sub6G small base station signals and WiFi signals to radiate the surrounding areas, thereby meeting the needs of high-bandwidth data services in the region to the greatest extent. Fig. 9 The data flow diagram of the fifth mode communication channel according to the embodiment of the present disclosure is schematically shown. As shown in Figure 9, two signal inputs can be used. One signal input channel obtains satellite signals from the phased array antenna and transmits the data to the converged communication system through the Ka-band high-throughput CPE terminal module. The other signal input channel obtains the operator network signal (ground coverage signal) from the 4 / 5G antenna and transmits the data to the converged communication system through the 4 / 5G terminal module. In this mode communication channel, both data channels remain in operation and dynamic scheduling is achieved according to the adaptive network selection algorithm.

[0074] In the embodiments of the present disclosure, the multi-mode fusion communication system is a device based on the integration of Ka-band satellite communication and multiple wireless communications, including multiple business functions such as Ka-band satellite terminal module function, Sub6G integrated small base station module function, 4 / 5G terminal module function, WiFi module function, GPS module function, and fusion system network management platform. The intelligent integration of multiple wireless communication schemes is realized, and the entire device realizes the integration of multiple access methods such as high-throughput satellite communication access, ground cellular network access, 5G small base station access, and WiFi access. According to different environmental conditions and different business scenarios, multiple communication methods are flexibly used to quickly establish high-throughput and high-bandwidth data channels, timely and effectively guarantee the smooth development of multiple business services, and realize the simultaneous processing of multi-mode and multi-standard signals of satellite terminals and ground base stations on a single chip. At the same time, the business channel is dynamically configured according to the real-time network status to realize intelligent scheduling, solve the problem of single satellite communication access mode, and realize multi-mode integration, so that the equipment availability is stronger, the business processing capability is better, the unit traffic cost is lower, and the communication quality and user perception are improved. In response to complex communication needs, the interoperability and interoperability of the system are guaranteed, efficient communication is achieved, and the performance and efficiency of the system are improved while ensuring the communication quality. The multi-mode fusion communication system not only reduces the hardware complexity, but also improves the compatibility and flexibility of the system. Each module is connected by a high-speed data bus to ensure efficient information transmission.

[0075] According to an embodiment of the present disclosure, the specific antenna includes a phased array antenna and / or a mobile communication antenna. In operation S210, based on the user's networking needs, receiving the first wireless communication signal through the specific antenna includes operations S2101-S2102.

[0076] In operation S2101, based on the user's networking needs, Ka-band satellite signals are received through a phased array antenna.

[0077] Collect user networking demand information through user device feedback, network management monitoring, or user active reporting. For example, determine whether the user needs high-speed data transmission (such as high-definition video streaming, large file downloads), real-time communication (such as voice calls, video conferencing), or general web browsing. Analyze the collected needs and determine the required network performance indicators, such as bandwidth, latency, reliability, etc. For example, high-definition video streaming may require a higher bandwidth to ensure smooth video, while real-time communication has stricter latency requirements.

[0078] Perform a self-test on the phased array antenna to ensure that the antenna hardware is working properly and obtain relevant parameters of the target Ka-band satellite, such as satellite orbital position, signal frequency, polarization mode, etc. These parameters are critical for accurately pointing to the satellite and correctly receiving the signal. According to the Ka-band satellite parameters, adjust the phased array antenna beam pointing to accurately align with the satellite. Start the receiving system to capture the signal and synchronize. Adjust the receiving parameters as needed to receive the Ka-band satellite signal.

[0079] In operation S2102, based on the user's networking demand, a ground coverage signal is received through a mobile communication antenna.

[0080] According to the user's networking needs, the requirements for network speed and stability are clarified. The process is the same as in the previous operation S2101 and will not be repeated here. In areas without satellite signal coverage, you can switch to the operator's 4 / 5G network mode and receive ground coverage signals through the mobile communication antenna (4 / 5G antenna).

[0081] According to an embodiment of the present disclosure, operation S220 uses a first physical layer of a preset chip to process a Ka-band satellite signal to obtain first network data, including operations S2201-S2203.

[0082] In operation S2201, the Ka-band satellite signal is converted using an intermediate frequency module to obtain a Ka-band baseband signal.

[0083] After being received by the phased array antenna, the Ka-band satellite signal enters the intermediate frequency module. This module first down-converts the high-frequency Ka-band satellite signal to reduce its frequency to a suitable intermediate frequency range. In this process, the signal generated by the local oscillator can be mixed with the signal through circuit components such as mixers. After that, the mixed signal is filtered to remove unnecessary clutter and interference signals. After a series of processing, the intermediate frequency signal is further converted into a baseband signal, and a Ka-band baseband signal that can be processed by the subsequent baseband chip is obtained.

[0084] In operation S2202, the Ka-band CPE terminal module in the first physical layer of the preset chip is used to process the Ka-band baseband signal to obtain physical layer data.

[0085] After the Ka-band baseband signal is obtained, it is processed with the help of the Ka-band CPE terminal module in the first physical layer of the preset chip (PC802 single chip). This module integrates specific functions and algorithms for Ka-band signal processing. It first demodulates the Ka-band baseband signal and restores the modulated signal carrying information to the original digital signal sequence. Then, it performs error correction coding operations to detect and correct bit errors that may occur during signal transmission to improve data accuracy. Then, signal equalization is performed to compensate for the distortion of the signal during transmission. After this series of processing, accurate and stable physical layer data is finally obtained, laying the foundation for further processing of the subsequent upper layer protocol stack.

[0086] In operation S2203, the physical layer data is processed by a protocol stack to obtain first network data.

[0087] After obtaining the physical layer data, it enters the protocol stack processing link to obtain the first network data. The protocol stack is like an orderly "data processing factory", which parses and processes the physical layer data layer by layer according to specific rules and processes.

[0088] First, the data will pass through the data link layer, which is responsible for converting the signal received by the physical layer into a data frame, adding the necessary frame header and frame trailer information, and performing error detection and correction. Next, the data enters the network layer, which performs routing selection based on information such as the IP address and determines the data transmission path. After that, it passes through the transport layer, which is responsible for establishing, maintaining, and managing end-to-end connections, and segmenting and reorganizing data. After these complex processes, the first network data is finally obtained in an orderly and standardized manner.

[0089] Fig.10 The wireless signal conversion flow chart of the ground access method of satellite communication according to an embodiment of the present disclosure is schematically shown.

[0090] like Fig.10 As shown, according to an embodiment of the present disclosure, the second wireless communication signal includes a wireless signal, and converting the first network data and / or the second network data into the second wireless communication signal in operation S240 includes operations S1010-S1020.

[0091] When the user demand is a wireless signal, the first network data and / or the second network data acquired in operation S220 may be further converted into a wireless signal.

[0092] In operation S1010, a portion of the first network data and / or the second network data is processed using the converged platform, and first control service data corresponding to the first network data and / or the second network data is sent to the wireless module.

[0093] In a complex communication architecture, the convergence platform plays a key role in connecting the upper and lower layers. It receives some of the possible first network data and possible second network data, which carry information from different sources and purposes. With its powerful processing capabilities, the convergence platform conducts in-depth analysis, intelligent integration, and optimization of this data.

[0094] After completing a series of processing, the fusion platform will filter out the corresponding first control service data (other control information and service data in the first network data and / or the second network data) from the first network data and / or the second network data. These control service data are crucial to the operation of the system and the realization of user functions. Subsequently, the fusion platform sends them to the wireless module.

[0095] In operation S1020, the first control service data is converted into a wireless signal through the multi-frequency antenna of the wireless module.

[0096] As a key link in the entire communication link, the wireless module quickly uses the multi-frequency antenna to work after receiving the data. The multi-frequency antenna has the ability to work in different frequency bands and can select the appropriate frequency band according to the data characteristics and transmission requirements. It modulates the first control service data and performs a series of conversion operations, and finally converts it into a wireless signal that can be propagated in space, realizing wireless transmission of information and meeting the diverse communication needs of users.

[0097] Fig.11 The following schematically shows a Sub6G small base station signal conversion flow chart of the ground access method for satellite communication according to an embodiment of the present disclosure.

[0098] like Fig.11 As shown, according to an embodiment of the present disclosure, the second wireless communication signal includes a Sub6G small base station signal, and operation S240 converts the first network data and / or the second network data into the second wireless communication signal, including operations S1110-S1120.

[0099] When the user demand is a Sub6G small base station signal, the first network data and / or the second network data obtained in operation S220 can be further converted into a Sub6G small base station signal.

[0100] In operation S1110, the fusion platform is used to process part of the first network data and / or the second network data, and the corresponding second control service data in the first network data and / or the second network data is sent to the Sub6G small base station module in the second physical layer of the preset chip.

[0101] The fusion platform receives part of the first network data and possible second network data. Based on its powerful algorithms and processing logic, the fusion platform conducts comprehensive and in-depth analysis and processing of these data, and screens out the second control service data corresponding to the first network data and / or the second network data according to the characteristics, purpose and system preset rules of the data. These data are of key significance for the specific function implementation and service control of the system. Subsequently, the fusion platform accurately sends the processed second control service data to the Sub6G small base station module in the second physical layer of the preset chip. This module is a key component in the system responsible for Sub6G frequency band signal processing and related business operations. After receiving the data from the fusion platform, it can further process and transform these control service data according to the working characteristics and communication requirements of the Sub6G small base station, laying a solid foundation for the subsequent efficient and stable communication services through the Sub6G small base station.

[0102] In operation S1120, the second control service data is converted into a Sub6G small base station signal using the radio frequency antenna of the Sub6G small base station module.

[0103] After the Sub6G small base station module of the second physical layer of the PC802 single chip receives the second control service data, its RF antenna is responsible for converting the data into a Sub6G small base station signal.

[0104] The RF antenna in the Sub6G small base station module is a key component to achieve this transformation. It works based on specific modulation technology and signal processing principles. The second control service data needs to be encoded and modulated first, and the data information is loaded onto a carrier signal of a specific frequency. These modulated signals have the characteristics of the Sub6G frequency band and meet the transmission requirements of Sub6G small base station signals. Then, the RF antenna radiates the modulated signal into the surrounding space in the form of electromagnetic waves, thereby successfully converting the second control service data into a Sub6G small base station signal that can be received and processed.

[0105] Fig.12 Another flow chart of the ground access method for satellite communication according to an embodiment of the present disclosure is schematically shown.

[0106] like Fig.12 As shown, the ground access method of satellite communication in this embodiment includes operations S210 to S240, and operations S1210 to S1230. The operations S210 to S240 described above will not be repeated here.

[0107] In operation S1210, business management data is collected using the converged platform.

[0108] As the management platform of the multi-mode converged communication system, the converged platform is responsible for processing the data, business, management, maintenance and other services of the entire system, and supports remote management and local management functions. It can be connected to the ground operation service center through a wired network through optical fiber or network cable and other media (the operation service center realizes unified management of various devices in the system, status monitoring, remote operation and maintenance, fee settlement, etc.).

[0109] In operation S1220, a state of the wired network interface is detected in real time.

[0110] The fusion platform can effectively manage the entire communication system. The status of the communication equipment can be monitored in real time at the operation service center. The fusion platform performs fault diagnosis, analysis, repair, and troubleshooting through the data and logs collected from the equipment status information. During the real-time monitoring process, if an abnormality is found in the equipment, the fusion platform will automatically alarm and autonomously repair the software program, reset the system in time, upgrade the software version, modify the equipment configuration, etc. If the system cannot be restored or the hardware is damaged, the fusion platform will report the current equipment failure status to the operation service center. The operation and maintenance personnel can contact the user as soon as possible to guide the user on the next repair operation process and assist the user in quickly and promptly resolving equipment problems. The management platform can effectively ensure the normal operation of each module of the equipment, improve the user experience, and better serve users.

[0111] In operation S1230, a multi-channel network backhaul method is used to transmit the business management data back to the operation service center based on the status of the wired network interface, so that the operation service center can monitor the status of the equipment in the multi-mode converged communication system in real time and perform remote operation and maintenance of the multi-mode converged communication system.

[0112] The multi-channel network backhaul method can realize multi-channel enhanced remote operation and maintenance. Fig.13 A schematic diagram of a data flow of a multi-channel network return according to an embodiment of the present disclosure is shown as follows: Fig.13As shown in the figure, usually a wired network is used to transmit data back to the operation service center. If the wired network is unstable, the data of the management platform can be transmitted back to the operation service center through the 4 / 5G terminal module to access the operator network, so as to realize enhanced remote operation and maintenance, and can realize real-time monitoring of data, repair of faults, management of equipment status, etc. At the same time, it can also realize local caching of business data, management of user behavior, storage of operation logs, etc. The multi-channel backhaul network is connected between the communication equipment and the operation service center in the multi-mode converged communication system, and the data channel can be established through wired backhaul or wireless backhaul. Since remote operation and maintenance requires the establishment of a data connection channel with the communication equipment, the status of the communication equipment can be monitored in real time at the operation service center, and the data and logs collected from the equipment status information can be used for fault diagnosis, analysis, repair and elimination. During the real-time monitoring process, if an abnormal situation is found in the equipment, the operation and maintenance personnel can operate and intervene through the remote connection, such as remotely restarting the equipment, modifying the equipment configuration, and upgrading the software version. The remote operation and maintenance of traditional satellite ground access devices is to connect the communication equipment with the operation service center through optical fiber or network cable. The stability of the wired network connection determines the efficiency of remote operation and maintenance. Stable remote connection can reduce downtime. In places where there is a lack of wired network connection, it is difficult to ensure that equipment failures are repaired in a timely manner. Using the multi-channel network backhaul method, the multi-channel backhaul network can effectively connect to the service platform through the data channel of wired backhaul or wireless backhaul, enhance the ability of remote operation and maintenance of equipment, and ensure that the operation service center can effectively monitor the status, troubleshoot, and upgrade firmware of user equipment at any location at any time, which greatly guarantees the stable operation of the equipment, ensures the timely repair of equipment failures, and improves the availability of the equipment.

[0113] Fig.14 A multi-channel backhaul flow chart of a ground access method for satellite communications according to an embodiment of the present disclosure is schematically shown.

[0114] like Fig.14 As shown, according to an embodiment of the present disclosure, in operation S1230, a multi-channel network backhaul method is used to backhaul business management data to an operation service center based on the state of a wired network interface, including operations S1410-S1420.

[0115] In operation S1410, if the state of the wired network interface is normal, the converged platform and the operation service center are connected through the wired network interface, and the service management data is transmitted back to the operation service center by using the wired network.

[0116] The multi-mode converged communication system retains the wired backhaul interface. Under the conditions (the wired network interface is normal), it can be connected to the operation service center through the wired backhaul network for remote operation and maintenance, and high-bandwidth and high-speed wired network backhaul can be achieved in areas with conditions for laying optical fiber or network cables.

[0117] In operation S1420, if the state of the wired network interface is abnormal, the converged platform and the operation service center are connected through the mobile operator network, and the service management data is transmitted back to the operation service center using the mobile communication module.

[0118] Generally, the communication equipment of the system is connected to the data switch by optical fiber or network cable. When these wired network interfaces are detected to be abnormal, the mobile operator network is used for data backhaul. In areas where there is no wired network connection, a higher rate of wireless backhaul is achieved through the mobile operator network (such as 4 / 5G wireless network). The wireless access of mobile communication modules (such as 4 / 5G terminal modules) adds a remote connection method for remote operation and maintenance.

[0119] like Fig.13 As shown in the figure, the fusion platform gives priority to using the wired network and transmits the business management data back to the operation service center through the wired network interface (such as: optical port or network port). However, in most outdoor usage environments, most users cannot use wired connection backhaul. The fusion platform of the device will automatically detect the status of the optical port and the network port. Once it detects that both the optical port and the network port cannot establish a connection with the operation service center, the 4 / 5G terminal module function will be automatically started. The fusion platform connects to the operation service center through the 4 / 5G operator network and sends relevant business management data.

[0120] The multi-mode converged communication system can be widely used in outdoor scenarios. Through the wireless backhaul connection of the 4 / 5G terminal module to the operation service center, the connectivity of remote operation and maintenance can be more effectively guaranteed, eliminating the complex connection requirements of the wired backhaul network, making the use of the system simpler and clearer. The relevant equipment will detect the connectivity of the wired connection. If the wired connection cannot be connected to the operation service center, the 4 / 5G terminal module function will be automatically started immediately. After the wireless connection is established, the device status and operation log can be reported to the operation service center. This connection operation is more convenient and applicable in outdoor scenarios.

[0121] The ground access method for satellite communications disclosed in the present invention provides a highly integrated and efficient wireless communication solution, greatly improves communication capacity and network availability, supports more users online at the same time, and reduces the cost per unit of traffic. It not only solves the problems faced by traditional single access methods, but also significantly improves the performance and service level of the overall system. While reducing costs and increasing efficiency, it helps to improve user perception and expand the user base.

[0122] Based on the above-mentioned ground access method for satellite communication, the present disclosure also provides a ground access device for satellite communication. Fig.15 The device is described in detail.

[0128] The signal access module 1540 is used to dynamically schedule the resource allocation ratio of the communication channel under different modes based on the optimal data transmission path, and convert the first network data and / or the second network data into a second wireless communication signal to access the second wireless communication signal to provide communication services to the user. In one embodiment, the signal access module 1540 can be used to perform the operation S240 described above, which will not be repeated here.

[0129] According to an embodiment of the present disclosure, the above-mentioned device 1500 also includes an operation and maintenance management module 1550 for collecting business management data using a converged platform; detecting the status of a wired network interface in real time; and using a multi-channel network backhaul method, based on the status of the wired network interface, backhauling the business management data to an operation service center, so that the operation service center can monitor the status of equipment in the multi-mode converged communication system in real time and perform remote operation and maintenance on the multi-mode converged communication system. In one embodiment, the signal access module 1540 can be used to perform the operations S1210-S1230 described above, which will not be repeated here.

[0130] According to an embodiment of the present disclosure, any multiple modules of the signal receiving module 1510, the signal processing module 1520, the routing module 1530, the signal access module 1540 and the operation and maintenance management module 1550 can be combined into one module for implementation, or any one of the modules can be split into multiple modules. Alternatively, at least part of the functions of one or more of these modules can be combined with at least part of the functions of other modules and implemented in one module. According to an embodiment of the present disclosure, at least one of the signal receiving module 1510, the signal processing module 1520, the routing module 1530, the signal access module 1540 and the operation and maintenance management module 1550 can be at least partially implemented as a hardware circuit, such as a field programmable gate array (FPGA), a programmable logic array (PLA), a system on a chip, a system on a substrate, a system on a package, an application specific integrated circuit (ASIC), or can be implemented by hardware or firmware such as any other reasonable way of integrating or packaging the circuit, or implemented in any one of the three implementation methods of software, hardware and firmware or in a suitable combination of any of them. Alternatively, at least one of the signal receiving module 1510, the signal processing module 1520, the routing selection module 1530, the signal access module 1540 and the operation and maintenance management module 1550 can be at least partially implemented as a computer program module, and when the computer program module is executed, the corresponding function can be executed.

[0131] Fig.16 The block diagram of an electronic device suitable for implementing a ground access method for satellite communication according to an embodiment of the present disclosure is schematically shown. Fig.16As shown, the electronic device 1600 according to an embodiment of the present disclosure includes a processor 1601, which can perform various appropriate actions and processes according to a program stored in a read-only memory (ROM) 1602 or a program loaded from a storage part 1608 to a random access memory (RAM) 1603. The processor 1601 may include, for example, a general-purpose microprocessor (e.g., a CPU), an instruction set processor and / or a related chipset and / or a dedicated microprocessor (e.g., an application-specific integrated circuit (ASIC)), etc. The processor 1601 may also include an onboard memory for caching purposes. The processor 1601 may include a single processing unit or multiple processing units for performing different actions of the method flow according to an embodiment of the present disclosure.

[0132] In RAM1603, various programs and data required for the operation of electronic device 1600 are stored. Processor 1601, ROM1602 and RAM1603 are connected to each other via bus 1604. Processor 1601 performs various operations of the method flow according to the embodiment of the present disclosure by executing the program in ROM1602 and / or RAM1603.
