Description

Technical Field

[0001] This application belongs to the field of satellite communication technology, and in particular relates to a satellite converged communication system based on a distributed gateway station dual-mode working mechanism. Background Technology

[0002] With the acceleration of global digitalization, communication demands are exploding, and traditional terrestrial networks are increasingly showing their limitations in terms of coverage and application scenarios. Satellite communication technology, especially low-Earth orbit satellite communication networks, has become an indispensable and important component of future communication systems due to its wide-area coverage and lack of terrain limitations. At the same time, the deep integration of satellite communication and terrestrial networks is becoming a key direction for the development of 6G and integrated space-air-ground networks.

[0003] However, the integration of satellite communication networks and terrestrial networks still faces many technical challenges. In particular, the gateway station, as a critical connection point between the satellite and terrestrial networks, directly impacts the performance, cost, and reliability of the entire system through its construction model and distribution. Traditional gateway stations typically employ a centralized construction model, requiring large-scale terrestrial infrastructure support. This results in high construction and maintenance costs, a lack of flexibility and resilience, and difficulty in responding to sudden communication demands or emergency scenarios. Traditional technologies include: 1) Centralized gateway station and terrestrial network interconnection technology like Figure 4 As shown, traditional satellite communication systems generally adopt a centralized gateway architecture, using a small number of large gateway stations to connect the satellite network with the ground core network. These gateway stations are usually located in remote areas, occupying large areas, with complex equipment, and incurring extremely high construction and maintenance costs.

[0004] In addition, existing patented technologies, such as the patent for "access node switching method, device and mobility management controller in MEO satellite", realize the unified management of LEO satellite and ground base station by MEO satellite, but still rely on centralized control at the satellite layer and fail to make full use of the distributed characteristics of the ground network.

[0005] 2) Space-Ground Resource Collaborative Management Technology In terms of satellite-ground resource coordination, existing technologies have proposed a variety of solutions. These include intelligent orchestration and uplink spectrum decoupling and pooling to integrate real-time sharing of all resources, such as time, frequency, space, and power, thereby improving uplink capabilities.

[0006] Other proposed technologies for low-Earth orbit satellites include an integrated coding and modulation system based on polar codes and a polar code-based bit-free synchronization-free algorithm. While these technologies can improve link stability and access efficiency, they focus more on air interface technology and do not solve the problem of distributed ground gateway facilities.

[0007] 3) Satellite-Ground Coordination Technology in Emergency Communications Currently, the commonly used emergency communication solution involving space-ground coordination employs innovative technologies such as drone swarms, satellite base stations, and intelligent optimization to achieve rapid communication recovery in extreme environments. This solution overcomes geographical limitations through the coordinated operation of multiple types of drones, enabling "signals to fall from the sky," including airdrop drones precisely delivering "portable base stations," relay drones extending signal transmission distances, and composite-wing drones providing dynamic coverage.

[0008] The disadvantages of existing technologies are as follows: The technology for connecting centralized gateway stations to terrestrial networks has significant technical bottlenecks: First, it has a high risk of single-point failure; if a gateway station fails or is damaged by a disaster, the entire satellite network service will be interrupted. Second, it suffers from high network latency, especially for scenarios requiring local service delivery, where all data must be transmitted over long distances to the gateway station and then back, resulting in unnecessary delays. Third, it is not flexible in terms of expansion, and cannot quickly adjust gateway capabilities according to changes in regional service needs.

[0009] Satellite-ground resource collaborative management technology and integrated coding and modulation systems based on polar codes mainly focus on spectrum resource sharing, with insufficient consideration for infrastructure collaboration.

[0010] In emergency communications, the space-ground coordination solution focuses on temporary communication restoration. Although it can quickly restore communication in scenarios such as emergency rescue and patrol mapping of areas without signal, it lacks deep coordination with the fixed facilities of ground operators.

[0011] The seamless handover method for data services in low-Earth orbit satellite 5G communication reduces signaling overhead and time delay caused by frequent disconnections and reconnections, but the handover decision still relies on the ground core network and fails to fully utilize the local decision-making capabilities of distributed gateway stations.

[0012] Therefore, it is necessary to provide a new satellite converged communication system based on a distributed gateway station dual-mode working mechanism to solve the above-mentioned technical problems. Summary of the Invention

[0013] The purpose of this disclosure is to provide a satellite converged communication system based on a distributed gateway station dual-mode working mechanism in order to solve the above-mentioned problems.

[0014] This disclosure achieves the above objectives through the following technical solutions: A satellite converged communication system based on a distributed gateway station dual-mode working mechanism includes a space segment, a ground segment, and a user segment; The space segment includes satellites in various orbits, which are equipped with reconfigurable payloads and inter-satellite links, support RAN and core network functions, and form a space network. The ground segment includes distributed gateway stations and ground operator super base stations, with the distributed gateway stations being distributedly embedded in the ground operator super base stations; The user segment includes various types of terminal devices, which support dual-mode or multi-mode access for satellite and terrestrial communication, and can select the optimal access method in different network environments.

[0015] As a further optimization of this disclosure, satellites in multiple orbits include low Earth orbit satellites, medium Earth orbit satellites, and geostationary orbit satellites.

[0016] As a further optimization of this disclosure, various types of terminal devices include satellite phones, vehicle-mounted terminals, shipborne terminals, and Internet of Things (IoT) devices.

[0017] As a further optimization of this disclosure, the distributed gateway station is embedded in the ground operator's super base station in the form of an integrated hardware and software module. The ground operator's super base station provides the distributed gateway station with infrastructure resources, including power supply, air conditioning system, transmission interface and equipment room space. The distributed gateway station can also utilize the existing transmission network of the ground operator's super base station to quickly access the operator's core network for local data storage or remote transmission.

[0018] As a further optimization of this disclosure, the distributed gateway station includes a radio frequency processing unit, a baseband processing unit, and a protocol conversion unit; The radio frequency processing unit is used to communicate with the satellite and operates in the satellite communication frequency band; The baseband processing unit is used for signal encoding / decoding and modulation / demodulation. The protocol conversion unit is used to convert between satellite communication protocols and terrestrial communication protocols, enabling seamless data transfer.

[0019] A satellite converged communication method applicable to the aforementioned satellite converged communication system based on a distributed gateway station dual-mode working mechanism includes the following steps: The system continuously monitors the connection status with the operator's core network through distributed gateway stations. If the connection status is normal, it continues to operate in non-emergency mode. Once a network interruption is detected, it automatically switches to emergency mode. In non-emergency operation mode, multiple distributed gateway stations are interconnected through the operator's bearer network to form a virtualized centralized high-bandwidth gateway station, providing a power supply link for satellite internet services; In emergency operation mode, each of the distributed gateway stations operates independently, providing a satellite path to connect to a centralized gateway station in another location via satellite, thereby connecting to the core network in other regions, achieving backup via satellite communication in addition to backhaul communication from the terrestrial bearer network.

[0020] As a further optimization of this disclosure, in the non-emergency working mode, the signal transmitted by the space satellite is simultaneously received by multiple distributed gateway stations within the coverage area, and each of the distributed gateway stations performs low-noise amplification, down-conversion and demodulation processing on the signal; Through the operator's bearer network, the signals received by the distributed gateway stations are transmitted to the central processing unit for merging and processing; The processed data is directly connected to the operator's core network after protocol conversion; for local services, the data is processed and exchanged locally. The management platform dynamically monitors the load status of each distributed gateway station, intelligently allocates service traffic, and achieves overall system load balancing.

[0021] As a further optimization of this disclosure, in emergency operation mode, each of the distributed gateway stations independently establishes a connection with the satellite and forwards data to the gateway station operating normally outside the disaster area via inter-satellite links, thereby accessing the remote core network; By employing a multi-network collaborative communication mode that integrates air, space, and ground networks, combined with surviving ground and satellite networks, and in conjunction with aerial drone base stations, a multi-dimensional emergency communication network can be constructed. Prioritize critical communications and dynamically allocate bandwidth resources based on the urgency of the business to ensure the communication needs of critical services, including command and dispatch and emergency rescue.

[0022] An electronic device includes a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus; Memory, used to store computer programs; The processor is used to execute the program stored in the memory to implement the satellite fusion communication method based on the distributed gateway station dual-mode working mechanism.

[0023] A computer-readable storage medium storing a computer program, which, when executed by a processor, implements the satellite fusion communication method based on a distributed gateway station dual-mode working mechanism.

[0024] The beneficial effects of this disclosure are as follows: This disclosure enables local delivery of satellite service data through distributed gateway stations, significantly reducing data transmission detours and lowering service latency. Simultaneously, the coordinated reception and signal combining of multiple distributed gateway stations effectively improves uplink signal quality. At the same transmit power, it enhances received signal strength, expands satellite signal coverage, and improves communication reliability in edge areas.

[0025] Furthermore, the distributed architecture brings path diversity, increasing system capacity through multiple parallel transmission paths. In non-emergency scenarios, the overall system capacity is several times greater than that of traditional centralized gateway architectures, better able to cope with the large-scale growth of future satellite internet services.

[0026] Multi-node distributed deployment avoids the risk of single points of failure, significantly improving system reliability and resilience. Even in the event of local node failure or damage to some facilities due to natural disasters, the system can still maintain basic communication services through surviving nodes. The distributed architecture also enhances the system's ability to resist targeted attacks. Because the nodes are widely distributed and structurally similar, it is difficult for attackers to paralyze the entire system through a single point of attack, thus improving system security.

[0027] In emergency scenarios, the system can be quickly reconfigured, utilizing satellite links to bypass damaged ground networks and provide continuous communication services to disaster areas. Compared with traditional emergency communication solutions, this system further shortens the response time and greatly improves the ability to guarantee emergency communication.

[0028] By sharing the infrastructure of terrestrial operators' super base stations, the construction cost of distributed gateway stations is significantly reduced. Simultaneously, by leveraging the existing transmission networks and power systems of super base stations, distributed gateway stations reduce the need for dedicated line laying, further saving network investment. In terms of maintenance, existing maintenance systems and resources of terrestrial operators can be utilized, reducing operation and maintenance costs.

[0029] Furthermore, by virtualizing baseband functions and sharing hardware resources, equipment costs and energy consumption can be further reduced. This system employs this technology, which further reduces the energy consumption of distributed gateway stations, aligning with the development trend of green communications.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] like Figure 1 As shown, a satellite converged communication system based on a distributed gateway station dual-mode working mechanism achieves efficient collaborative communication in both non-emergency and emergency scenarios by distributing satellite gateway station functions across multiple super base stations operated by ground operators. The system architecture consists of three parts: space segment, ground segment, and user segment, forming a complete integrated air-space-ground communication system.

[0034] The space segment comprises satellite nodes in various orbits (GEO, MEO, LEO), equipped with reconfigurable payloads and inter-satellite links, enabling them to support RAN and core network functions and form a complex space network. In particular, low-Earth orbit satellite constellations, such as the China StarNet and Starlink Phase II mega-constellations, achieve deep integration with terrestrial networks through 3GPP NTN standardization.

[0035] The ground segment is the core innovation of this invention, consisting of distributed gateway stations, terrestrial operator super base stations, a bearer network, and core network elements. The distributed gateway stations, serving as the connection points between the satellite network and the terrestrial network, no longer adopt the traditional centralized construction model, but are instead distributedly embedded within multiple super base stations of the terrestrial operator.

[0036] The user segment includes various types of terminal devices, such as satellite phones, vehicle-mounted terminals, shipborne terminals, and IoT devices. These terminals support dual-mode or multi-mode access for both satellite and terrestrial communication and can select the optimal access method in different network environments.

[0037] The distributed gateway station in this invention is not a standalone physical facility, but rather embedded as an integrated hardware and software module within existing super base stations of terrestrial operators. These super base stations typically possess powerful processing capabilities, ample power backup, and advantageous geographical locations, providing an ideal deployment environment for the distributed gateway station.

[0038] Each distributed gateway module comprises three core components: a radio frequency (RF) processing unit, a baseband processing unit, and a protocol conversion unit. The RF processing unit is responsible for communicating with the satellite and operates in satellite communication frequency bands (such as Ka, Ku, and Q / V bands); the baseband processing unit performs signal encoding / decoding, modulation / demodulation, and other functions; and the protocol conversion unit completes the conversion between satellite communication protocols and terrestrial communication protocols, enabling seamless data transfer.

[0039] Distributed gateway stations share infrastructure resources with super base stations, including power supply, air conditioning systems, transmission interfaces, and equipment room space, significantly reducing construction and operating costs. Simultaneously, leveraging the existing transmission network of super base stations, distributed gateway stations can quickly access the operator's core network, enabling local data storage or remote transmission.

[0040] Working mechanisms in non-emergency scenarios, such as Figure 2 As shown: In non-emergency scenarios, multiple distributed gateway stations are interconnected through the high-performance bearer network of terrestrial operators, forming a virtualized centralized high-bandwidth gateway station to provide power supply links for satellite internet services. This "distributed deployment, centralized management" model combines flexibility and efficiency.

[0041] The specific workflow is as follows: 1. Satellite signal reception and demodulation: The signals transmitted by the space satellite are simultaneously received by multiple distributed gateway stations within the coverage area. Each gateway station performs low-noise amplification, down-conversion, and demodulation on the signals.

[0042] 2. Signal Combining and Processing: Signals received by multiple distributed gateway stations are transmitted to the central processing unit for merging and processing via the bearer network. Utilizing multiple-input multiple-output (MIMO) technology and signal processing algorithms, signal quality is effectively improved and the bit error rate is reduced.

[0043] 3. Data Routing and Switching: Processed data is directly connected to the operator's local core network after protocol conversion, enabling rapid local satellite service data delivery. For local services, data does not need to be transmitted over long distances; it is processed and switched directly locally, significantly reducing transmission latency.

[0044] 4. Resource Coordination and Load Balancing: The system dynamically monitors the load status of each distributed gateway station through an AI-powered management platform, intelligently allocates business traffic, and achieves overall system load balancing.

[0045] Working mechanisms in emergency scenarios, such as Figure 3 As shown: When a disaster causes a large-scale disruption to the terrestrial network, the system automatically switches to emergency operating mode. At this time, each distributed gateway station can operate independently, providing a satellite connection to a centralized gateway station in another location, thereby connecting to the core network in other regions. This allows for satellite communication as a backup, in addition to backhaul communication from the terrestrial bearer network.

[0046] The specific workflow in emergency scenarios includes: 1. Autonomous detection and mode switching: The distributed gateway station continuously monitors the connection status with the ground core network. Once a network interruption is detected, it automatically switches to emergency working mode.

[0047] 2. Establishment of independent satellite links: In emergency mode, each distributed gateway station independently establishes a connection with the satellite and forwards data to the gateway station that is working normally outside the disaster area through the inter-satellite link, thus accessing the remote core network.

[0048] 3. Multi-link collaborative transmission: Using an "air-space-ground" multi-network collaborative communication mode, combining surviving ground networks and satellite networks, and cooperating with aerial drone base stations, a multi-dimensional emergency communication network is constructed.

[0049] 4. Dynamic resource allocation: In emergency mode, the system prioritizes critical communications and dynamically allocates bandwidth resources according to the urgency of the business to ensure the communication needs of critical businesses such as command and dispatch and emergency rescue.

[0050] The advantages of this solution compared to existing technologies are as follows: 1) Significantly improves network performance and user experience This solution enables local data delivery for satellite services through distributed gateway stations, significantly reducing data transmission detours and lowering service latency. Real-world testing data shows that for local services, it effectively reduces end-to-end latency and significantly improves user experience.

[0051] Meanwhile, through coordinated reception and signal combining of multiple distributed gateway stations, the uplink signal quality was effectively improved. At the same transmit power, the received signal strength was increased, expanding the satellite signal coverage and enhancing communication reliability in edge areas.

[0052] Furthermore, the distributed architecture brings path diversity, increasing system capacity through multiple parallel transmission paths. In non-emergency scenarios, the overall system capacity is several times greater than that of traditional centralized gateway architectures, better able to cope with the large-scale growth of future satellite internet services.

[0053] 2) Enhance system reliability and resilience This solution avoids single-point-of-failure risks through multi-node distributed deployment, significantly improving system reliability and resilience. Even in the event of local node failure or damage to some facilities due to natural disasters, the system can still maintain basic communication services through surviving nodes. The distributed architecture also enhances the system's ability to resist targeted attacks. Because the nodes are widely distributed and structurally similar, it is difficult for attackers to paralyze the entire system through a single point of attack, thus improving system security.

[0054] In emergency scenarios, the system can be quickly reconfigured, utilizing satellite links to bypass damaged ground networks and provide continuous communication services to disaster areas. Compared with traditional emergency communication solutions, this system further shortens the response time and greatly improves the ability to guarantee emergency communication.

[0055] 3) Reduce construction and operating costs By sharing the infrastructure of terrestrial operators' super base stations, this solution significantly reduces the construction cost of distributed gateway stations. Compared to building new traditional centralized gateway stations, the construction and deployment costs of this solution are expected to be reduced by 40%-60%, mainly due to cost reductions in site rental, civil engineering facilities, and energy-saving cooling.

[0056] Meanwhile, distributed gateway stations leverage the existing transmission network and power system of super base stations, reducing the need for dedicated line laying and further saving network investment. In terms of maintenance, they can rely on the existing maintenance systems and resources of ground operators, reducing operation and maintenance costs.

[0057] Furthermore, by virtualizing baseband functions and sharing hardware resources, equipment costs and energy consumption can be further reduced. This system employs this technology, which further reduces the energy consumption of distributed gateway stations, aligning with the development trend of green communications.

[0058] 4) Promote deep integration of satellite and ground networks and business innovation This solution provides infrastructure-level support for the deep integration of satellite and terrestrial networks, enabling the two networks to evolve from simple interconnection to a new stage of resource sharing and collaborative services as proposed in this invention. This deep integration creates favorable conditions for the development of innovative services.

[0059] In the low-altitude economy, for example, the system can provide wide-area coverage and precise positioning services for drone logistics and air traffic management; in the Internet of Things (IoT) field, it supports low-power wide-area connectivity for a large number of sensor nodes. These innovative services will drive the comprehensive development of the digital economy, achieve deep integration of satellite internet with vertical industries, and create significant socio-economic benefits.
