Description

Technical Field

[0001] The present invention relates to the field of communication networking technology, and in particular to a large-scale air-to-ground communication networking system, method, equipment, medium and product. Background Art

[0002] Mesh ad hoc network technology is one of the commonly used technologies for air-to-ground communication of low-altitude aircraft. The ad hoc network system is a mobile broadband multimedia communication system designed with a new "wireless mesh network" concept. The latest ad hoc network integrates multi-input and multi-output technology and supports Mesh broadband ad hoc network functions. The Mesh broadband ad hoc multimedia broadband transmission system has powerful functions and excellent performance. All nodes can use a distributed network architecture of a centerless ad hoc network under non-line-of-sight and fast-moving conditions to achieve real-time interaction of multi-channel voice, data, images and other multimedia information. Mesh ad hoc network supports any network topology, such as point-to-point, point-to-multipoint, chain relay, mesh network and hybrid dynamic topology, etc., providing low-altitude UAV systems with reliable, timely, safe and efficient voice, data, video and visual command and dispatch and other rich comprehensive services, to meet the wireless broadband communication needs of low-altitude UAVs in normal or emergency situations to the greatest extent, and truly realize "communication on demand anytime, anywhere".

[0003] However, each communication device in the ad hoc network needs to synchronize signaling and other data with other communication devices, which will consume a certain amount of air interface resources. When the number of communication devices is not large, the system can maintain normal signaling overhead and data communication. However, when the number of communication devices in a network increases, especially when an aerial mesh networking architecture is adopted, all communication devices need to be interconnected with other communication devices in the system and synchronize signaling, which will cause the signaling overhead to grow exponentially. This is also the reason why ad hoc network technology is generally used in small-scale, flexibly deployable drone low-altitude communication scenarios, and cannot be applied to large-scale networking applications. Summary of the invention

[0004] The present invention provides a large-scale air-to-ground communication networking system, method, device, medium and product, which are used to solve the problem that the large-scale air-to-ground communication networking mode in the prior art is not suitable for large-scale networking applications.

[0005] In a first aspect, the present invention provides a large-scale air-to-ground communication networking system, including a ground control center and a plurality of communication sub-networks; each of the communication sub-networks uses a different network identifier; The ground control center is used to manage and monitor the communication network operation of the multiple communication sub-networks in the entire large-scale open space; Each of the communication sub-networks is used to provide communication services for a specific geographical area within the large-scale open space.

[0007] In one embodiment, an air gateway is deployed on any of the low-altitude aircraft; The aerial gateway is used to connect data transmission between the ground station and multiple communication devices deployed on the low-altitude aircraft.

[0008] In one embodiment, the link between the ground station and the plurality of low-altitude aircraft is a direct link.

[0009] In one embodiment, a link between any two low-altitude aircraft among the plurality of low-altitude aircraft is a relay link.

[0010] In one embodiment, a ring network redundant architecture is used between ground stations in each of the communication subnetworks.

[0011] In a second aspect, the present invention further provides a large-scale air-to-ground communication networking method, comprising: Divide large vacant lots into specific geographic areas; Deploy a geographically specific ground station, multiple low-altitude aircraft, and user terminals within each specific geographical area; A ground station, a plurality of low-altitude aircraft and user terminals deployed in each specific geographical area form a communication sub-network, and a network identifier is set for the communication sub-network; the network identifier set for each communication sub-network is different; The communication network operation of the multiple communication sub-networks is managed and monitored by the ground control center.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The terms "first", "second", etc. in the present invention are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention can be implemented in an order other than those illustrated or described herein.

[0023] Combine the following Figure 1-Figure 4 The large-scale air-to-ground communication networking system, method, device, medium and product provided by the present invention are described.

[0024] Combination Figure 1 and Figure 2 , Figure 1 is a structural diagram of a large-scale air-to-ground communication networking system provided by the present invention, Figure 2 It is a schematic diagram of the network architecture of the large-scale air-to-ground communication networking system provided by the present invention.

[0025] like Figure 1 As shown, the large-scale air-to-ground communication networking system provided by the present invention includes a ground control center and multiple communication sub-networks, each of which uses a different network identifier; The ground control center is used to manage and monitor the communication network operation of the multiple communication sub-networks in the entire large-scale open space; Each of the communication sub-networks is used to provide communication services for a specific geographical area within the large-scale open space.

[0026] Specifically, when conducting large-scale air-to-ground communication networking, the large-scale open space can be divided into multiple specific geographical areas according to preset division rules by manual or computing equipment. Of course, the communication networking method of the present invention is not only applicable to large-scale open spaces, but also to small-scale open spaces. It just needs to be decided according to the actual situation, among which the preset division rules are set according to the actual situation.

[0027] Furthermore, a communication sub-network is deployed in each specific geographical area, and the communication sub-network provides communication services in the specific geographical area, and a specific network identifier (Identity document, ID) is set for each communication sub-network. Therefore, the network ID set for each communication sub-network is different, such as Figure 2As shown. The communication subnetworks corresponding to different network IDs are isolated from each other, that is, they will not interfere with each other or communicate with each other in data transmission and communication, which helps to ensure the independence and security of each subnetwork. More importantly, each communication device in different communication subnetworks only needs to synchronize signaling and other data with other communication devices in the same communication subnetwork, and does not need to synchronize signaling and other data with communication devices in other communication subnetworks. This can reduce the exponential synchronization signaling overhead between communication devices, support the wireless expansion of communication devices in the self-organizing network, and is no longer limited by the signaling overhead in the traditional self-organizing network.

[0028] In addition, these network IDs may provide customized communication coverage and services within their specific geographic areas based on different protocols, frequencies or technical standards, thereby providing diversified communication coverage and services for the entire large-scale space.

[0029] Furthermore, after the corresponding communication sub-network is deployed in each specific geographical area, the communication network operation of multiple communication sub-networks in the entire large-scale airspace is managed and monitored by the ground control center.

[0030] The ground control center is the core management node of the entire system. The ground control center communicates with each communication sub-network through a special management interface to ensure the coordinated operation and service quality of each communication sub-network. The main functions of the ground control center include network management and control, resource allocation and scheduling, and security and fault handling. Network management and control specifically refers to the configuration, management and monitoring of the entire networking system. Resource allocation and scheduling specifically refers to the management of the allocation of communication resources to ensure the efficient operation of the system. Security and fault handling specifically refers to handling security issues and fault management in the system to ensure the stability and security of the system.

[0031] In addition to managing the connection and collaboration of each communication sub-network, the ground control center is also responsible for real-time monitoring of the operating status and performance of each communication sub-network, including monitoring key indicators such as network load, signal strength, and data transmission rate to ensure stable communication operation and service quality.

[0032] Overall, this large-scale air-to-ground communication networking system achieves effective communication coverage and management of vast areas in the air and on the ground through a ground control center and multiple communication sub-networks using different network identifiers, providing efficient and reliable communication solutions for a variety of application scenarios.

[0033] Optionally, each of the communication subnetworks includes a ground station at a specific geographical location, a plurality of low-altitude aircraft and user terminals within the specific geographical area; The ground station is used to communicate with the multiple low-altitude aircraft and transmit the communication data fed back by the multiple low-altitude aircraft to the user terminal; Any of the low-altitude aircraft is used to provide communication services within the specific geographical range; The user terminal is used to obtain corresponding communication services according to the user's communication needs.

[0034] Specifically, the internal architecture of each communication sub-network adopts the existing Mesh self-organizing network architecture. Therefore, each communication sub-network includes a ground station in a specific geographical location, multiple low-altitude aircraft and user terminals in the specific geographical location, thereby constructing a grouped networking architecture of air subnet + ground station gateway based on different network IDs, such as Figure 2 As shown, the exponential synchronization signaling overhead between terminals is effectively reduced.

[0035] Therefore, the process of deploying a communication sub-network in each specific geographical area can be understood as deploying a ground station at a specific geographical location, multiple low-altitude aircraft and user terminals in each specific geographical area, and forming a communication sub-network with a ground station, multiple low-altitude aircraft and user terminals deployed in each specific geographical area.

[0036] The following describes the network architecture of a communication subnetwork.

[0037] When a user has a communication need, the user terminal will obtain the required information or communicate through the communication services provided by the ground station from the low-altitude aircraft based on the user's communication needs. The communication connection between the user terminal and the ground station is usually achieved through a ground network connection. Of course, one or more user terminals can be deployed, depending on actual needs.

[0038] Furthermore, a user terminal can control one or more low-altitude aircraft to provide communication services. Therefore, after the ground station receives the communication requirements sent by the user terminal, it will determine the one or more low-altitude aircraft controlled by it. The ground station is located in a specific geographical location and is usually a fixed infrastructure that can establish communication links with multiple low-altitude aircraft. This includes ensuring that the ground station can effectively communicate with the low-altitude aircraft in two directions through verified communication protocols and frequency bands. Therefore, after the ground station determines the low-altitude aircraft controlled by the user terminal, it dispatches the corresponding low-altitude aircraft to perform communication services that can meet the user's communication needs.

[0039] Furthermore, after receiving the dispatch instruction sent by the ground station, the low-altitude aircraft will execute the corresponding communication service and feed back the communication data generated by the execution to the ground station, wherein the executed communication service may be data transmission, voice call, video transmission, etc. Low-altitude aircraft are usually drones or other unmanned aerial vehicles. Low-altitude aircraft are deployed in a specific geographical area to provide communication services by flying in the air. In addition, low-altitude aircraft can carry communication equipment and related sensors to maintain communication coverage in the air and collect sensor data, etc.

[0040] Furthermore, the ground station transmits the communication data fed back by one or more low-altitude aircraft to the user terminal so that the user can obtain high-quality communication service experience.

[0041] It is understandable that the ad hoc networking technology uses time division multiplexing technology to carry different services through different time slots, while the original ad hoc networking method only uses one ground station, which is equivalent to the air interface aggregation device in the air-to-ground communication network. When the ground station needs to access a large number of devices, the air-to-ground communication capacity bottleneck will be caused due to the limitation of the number of time slots. The embodiment of the present invention divides the large-scale network into multiple communication sub-networks, and each communication sub-network is deployed with a ground station. Therefore, the ground station is expanded from one to multiple, supporting multiple gateways to connect with the ground control center, which effectively solves the capacity bottleneck problem. Each ground station also serves as the export gateway of the aerial equipment in different communication sub-networks. Referring to the design of the gateway switch of the wired network, it is responsible for forwarding the air-to-ground communication services within the communication sub-network, and at the same time realizes the data interconnection between the export gateways of different communication sub-networks through the wired ring network.

[0042] Optionally, an aerial gateway is deployed on any of the low-altitude aircraft; The aerial gateway is used to connect data transmission between the ground station and multiple communication devices deployed on the low-altitude aircraft.

[0043] Specifically, an aerial gateway and multiple communication devices are deployed on low-altitude aircraft. The aerial gateway can connect the data transmission between the ground station and multiple communication devices deployed on the low-altitude aircraft. These communication devices may include radio transmitters of different frequency bands, antenna systems, and related data processing and forwarding equipment.

[0044] The aerial gateway is highly flexible and adaptable, and can adjust its working mode and frequency according to environmental conditions and communication requirements. It ensures that in complex low-altitude environments, multiple communication devices on low-altitude aircraft can effectively establish reliable data connections with ground stations. Therefore, the aerial gateway can transmit the communication data, feedback information or real-time monitoring data collected on low-altitude aircraft back to the ground station, enabling the ground station to effectively monitor and manage the operating status of low-altitude aircraft.

[0045] Optionally, the link between the ground station and the multiple low-altitude aircraft is a direct link.

[0046] The links between the ground station and multiple low-altitude aircraft use direct links, which can be considered a point-to-point communication architecture, which means that each low-altitude aircraft directly establishes an independent communication connection with the ground station without going through an intermediate node or a public network. This point-to-point direct connection helps ensure the real-time, security and stability of data transmission, and is particularly suitable for tasks that require rapid response and high-frequency data exchange, such as real-time monitoring, emergency rescue and safety monitoring.

[0047] Optionally, a link between any two low-altitude aircraft among the multiple low-altitude aircraft adopts a relay link.

[0048] Specifically, if Figure 2 As shown, the link between any two low-altitude aircraft among multiple low-altitude aircraft adopts a relay link, which can be considered as a distributed network architecture. In this architecture, the communication between low-altitude aircraft is not a direct point-to-point connection, but data transmission through relay nodes. In other words, each low-altitude aircraft can act as a node and establish a connection with each other through a relay link, thus forming a distributed network. The characteristic of a distributed network is that there is no central control node, and each node communicates and cooperates with each other through direct or indirect connections. This method can effectively expand the communication coverage, enhance signal stability, and provide flexible network management and expansion capabilities. It is suitable for communication needs that need to cover a large area or complex environment.

[0049] Optionally, a ring network redundant architecture is adopted between the ground stations in each of the communication subnetworks.

[0050] Specifically, if Figure 2 As shown in the figure, a ring network redundancy architecture is used between the ground stations in each communication sub-network, that is, a ring network redundancy architecture is used between multiple ground stations deployed in large-scale airspace. The ring redundancy architecture is a network design in which each node is connected to other nodes in the network through multiple paths to form a ring structure. This design helps to improve the reliability and fault tolerance of the network, because even if one of the paths fails, the data can still be bypassed through other paths, which will not affect the operation of the entire communication sub-network, ensuring the sustainability and stability of communication.

[0051] The ground station adopts a ring network redundancy design, which can avoid single point failures through the ring protection protocol and improve the reliability of the ground station. At the same time, the ring network design can make the ground stations connected to the ground control center not restricted by geographical location and quantity. The ground stations can be deployed separately and over long distances to avoid frequency interference problems. In the future, it can be flexibly expanded according to business needs, and plug-and-play can be achieved by simply adding a ring network switch.

[0052] The large-scale air-to-ground communication networking system provided by the present invention utilizes the networking characteristics of the network identifier in the self-organizing networking technology to design a large-scale network into different communication sub-networks, each of which is responsible for the communication services of a specific geographical area in the large-scale air-to-ground. The ground control center manages and monitors the communication network operations of multiple communication sub-networks to achieve the construction of a distributed network architecture, and each communication sub-network uses a different network identifier. The communication sub-networks with different network identifiers are not interoperable. Therefore, each communication device in each communication sub-network only needs to synchronize signaling and other data with other communication devices in the communication sub-network, and does not need to synchronize signaling and other data with communication devices in other communication sub-networks. In the scenario of large-scale networking, the signaling resource consumption can be greatly reduced, the wireless expansion of communication devices in the self-organizing network can be supported, and the available network transmission bandwidth can be effectively improved.

[0053] Further, Figure 3 Schematic diagram of the flow of the large-scale air-to-ground communication networking method provided by the present invention. Figure 3 The IT cloud resource pool network composition method provided by the present invention may include: Step 301, dividing a large-scale vacant land into a plurality of specific geographical areas; Step 302: deploy a ground station at a specific geographical location, multiple low-altitude aircraft, and user terminals in each specific geographical area; Step 303: a ground station, a plurality of low-altitude aircraft and user terminals deployed in each specific geographical area are formed into a communication sub-network, and a network identifier is set for the communication sub-network; the network identifier set for each communication sub-network is different; Step 304: Manage and monitor the communication network operation of the multiple communication sub-networks through the ground control center.

[0054] Specifically, when conducting large-scale air-to-ground communication networking, the large-scale open space can be divided into multiple specific geographical areas according to preset division rules by manual or computing equipment. Of course, the communication networking method of the present invention is not only applicable to large-scale open spaces, but also to small-scale open spaces. It just needs to be decided according to the actual situation, among which the preset division rules are set according to the actual situation.

[0055] Furthermore, a communication sub-network is deployed in each specific geographical area, and the communication sub-network provides communication services in the specific geographical area, and a specific network identifier (Identity document, ID) is set for each communication sub-network. Therefore, the network ID set for each communication sub-network is different, such as Figure 2 As shown. The communication subnetworks corresponding to different network IDs are isolated from each other, that is, they will not interfere with each other or communicate with each other in data transmission and communication, which helps to ensure the independence and security of each subnetwork. More importantly, each communication device in different communication subnetworks only needs to synchronize signaling and other data with other communication devices in the same communication subnetwork, and does not need to synchronize signaling and other data with communication devices in other communication subnetworks. This can reduce the exponential synchronization signaling overhead between communication devices, support the wireless expansion of communication devices in the self-organizing network, and is no longer limited by the signaling overhead in the traditional self-organizing network.

[0056] In addition, these network IDs may provide customized communication coverage and services within their specific geographic areas based on different protocols, frequencies or technical standards, thereby providing diversified communication coverage and services for the entire large-scale space.

[0057] Furthermore, after the corresponding communication sub-network is deployed in each specific geographical area, the communication network operation of multiple communication sub-networks in the entire large-scale airspace is managed and monitored by the ground control center.

[0058] The ground control center is the core management node of the entire system.
