Technical Field

[0001] This application relates to the field of 5G airborne wireless communication technology, and in particular to an airborne terminal, network connection method, device, equipment, medium and program product. Background Technology

[0002] 5G modules and customer premises equipment (CPE) only support access to ordinary terrestrial 5G networks, while 5G air-to-ground (ATG) networks can support higher maximum mobile speeds and longer coverage distances, far exceeding ordinary 5G networks.

[0003] However, current 5G modules and 5G ATG modules can only access their respective networks. For example, 5G or ATG modules used on airplanes can only support a single network. As a result, since airplanes need to connect to different networks at different stages of flight, they need to carry two modules that support different networks and manually select which module to connect to, which is cumbersome.

[0062] 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.

[0063] 5G wireless transmission is short for fifth-generation mobile communication technology, a major upgrade from 4G technology. Compared to 4G, 5G wireless transmission offers higher speeds, lower latency, and greater connection capacity, meeting the ever-increasing data demands.

[0064] With the rapid development of the low-altitude economy, low-altitude internet will serve as the infrastructure for the low-altitude economy, covering the low-altitude range below 1,000 meters. A large number of unmanned aerial vehicles have the need to access 5G networks for communication, and the need for research and development and adaptation of airborne 5G communication modules is becoming increasingly urgent.

[0065] 5G ATG is a wireless network technology system based on 5G technology with deep customization and modification. It provides a high-speed air-to-ground communication network for civil aircraft flying at altitudes up to 12,000 meters and speeds up to 1,200 km / h. The maximum coverage radius of the ATG ground base station can reach 300 km, and the airborne end uses dedicated ATG airborne CPE equipment to achieve wireless access and data transmission with the ground ATG base station. Because the airborne CPE modules are all custom-developed, they only support access to the ATG network and cannot access ordinary terrestrial 5G networks.

[0066] The 5G module only supports access to ordinary terrestrial 5G networks, with a maximum mobile speed of 500km / h and a maximum access radius of 102km (3GPP R15 standard); while 5G ATG, due to customized modifications to related protocols and access channels, supports a maximum mobile speed of 1200km / h and a maximum access distance of 300km, far exceeding the standard 5G network.

[0067] However, both 5G modules and ATG modules can only access their respective networks and cannot be compatible with both standard 5G and ATG networks simultaneously. When aircraft use general 5G or ATG modules, they can only support a single network and cannot meet the requirement of seamless network connectivity from the ground to flight to high altitude.

[0068] Related technologies include an airborne router device based on 5G communication technology, which includes a main control board and an interface board, a SIM card board, and a power board connected to the main control board. This device applies 5G communication technology to the access port for cabin internet interaction, achieving internet speeds exceeding 1Gbps. Another technology is a wireless caching recorder based on 5G technology, comprising a power module, a data management module, a storage module, and a wireless communication module, overcoming the problems of slow transmission speed and low transmission success rate in traditional caching recorders during actual use.

[0069] The aforementioned airborne 5G technologies all use single-mode 5G modules for wireless access and data transmission and reception. As an airborne data transmission device, it transmits relevant airborne data back to the ground. The single-mode standard 5G module is used for network connection, which can only be achieved when there is 5G network coverage on the ground.

[0070] The related technologies also include an airborne terminal and method for a Worldwide Interoperability for Microwave Access (WiMAX) and 5G dual-mode Aeronautical Mobile Airport Communications System (AeroMACS). The hardware components mainly include a baseboard, an adapter board, and a protocol processing board. The protocol processing board includes a WiMAX and 5G dual-mode module, a core processor, a flight data storage circuit module, an external interface control module, and a power supply module. It simultaneously implements both 5G and WiMAX communication standards on a single module, incorporating 5G communication functionality. This overcomes the technical shortcomings of lacking airborne terminal products during the promotion of the AeroMACS system, improving the security and efficiency of airborne aviation data transmission.

[0071] The aforementioned structure integrates both 5G and WiMAX chips onto a single board, sharing a common antenna. Both WiMAX and the aforementioned 5G module can only establish data connections when there is 5G network coverage on the ground; they cannot connect during flight or at high altitudes.

[0072] This application provides an airborne terminal, a network connection method, an apparatus, a device, a medium, and a program product to solve the problem of cumbersome operation when connecting a module to a corresponding network.

[0073] See Figure 1 , Figure 1 This is a schematic diagram of the structure of an airborne terminal provided in an embodiment of this application, as shown below. Figure 1 As shown, it includes:

[0074] The first communication module 11 is used to receive a first network signal, wherein the first network signal is a network signal used for terrestrial communication.

[0075] The second communication module 12 is used to receive a second network signal, which is a network signal of an air-to-ground ATG network.

[0076] The main control unit 13 is connected to both the first communication module 11 and the second communication module 12. The main control unit is used to control the first communication module 11 to receive the first network signal and / or control the second communication module 12 to receive the second network signal according to the flight parameters of the flight equipment.

[0077] The dual modules of the airborne terminal need to work in different network modes. Therefore, the airborne 5G transmission subsystem is divided into two subsystems: the airborne data transmission subsystem (i.e., the airborne subsystem) and the ground data processing subsystem.

[0078] like Figure 2 As shown, the airborne data transmission subsystem is an airborne subsystem consisting of an airborne 5G terminal (including an airborne 5G main module and an airborne 5G sub-module) and a 5G antenna (supporting two antenna schemes: dual modules sharing one antenna and separate independent antennas). It is responsible for transmitting airborne data to the 5G / ATG base station. The data processing subsystem, consisting of a data receiving-processing module and a high-speed data storage module, is located on the ground. It is used to receive airborne data sent from the 5G base station, perform cyclic redundancy check (CRC) verification, perform fusion storage, and then transmit it to the application server.

[0079] The primary function of the airborne 5G terminal (i.e., the airborne terminal) is to enable high-speed communication between the 5G base station and the ground service equipment. Since it needs to simultaneously support both the standard 5G protocol and 5G ATG (Advanced Transmission Protocol) wireless access protocols, the 5G communication module comprises two distinct communication modules: a first communication module (also called the main module) 11 and a second communication module (also called the secondary module) 12. The first communication module 11 supports the standard 5G protocol and the mainstream frequency bands used by operators, and is used to receive signals from the first network. The second communication module 12 supports the 5G-ATG protocol and operates on the 4.9GHz frequency band, and is used to receive signals from the second network.

[0080] The first communication module 11 and the second communication module 12 are both connected to the main control unit 13. The main control unit 13 controls the opening and closing of the two communication modules according to the flight parameters of the flight equipment.

[0081] The first network signal is a signal used for ground communication, such as a terrestrial 5G network; the ATG network is a network used for airborne access. When the flight equipment is on the ground or at a low altitude, it can access the ground network through the first communication module; when the flight altitude is high, it can access the ATG network through the second communication module.

[0082] When the first communication module 11 is turned on, it can receive a first network signal; when the second communication module 12 is turned on, it can receive a second network signal. When both communication modules are turned on, they can receive network signals from two different networks, or the communication module corresponding to the network with the better signal can be controlled to receive the network signal. For example, when the first network signal is better, the first communication module 11 receives the first network signal; when the second network signal is detected to be better, the system switches to the second communication module 12 to receive the second network signal, achieving rapid network switching.

[0083] Optionally, such as Figure 1 As shown, the main control unit 13 includes a main control board 131. The main control board 131 is connected to the first communication module 11 through a first connector 132 and to the second communication module 12 through a second connector 133. The main control board 131 is used to decide the processing method of data from the first communication module and the second communication module.

[0084] The main control board 131 of the main control unit 13 is connected to the first communication module 11 via a first connector (such as a board-to-board connector) 132, and to the second communication module 12 via a second connector (such as a board-to-board connector) 133. All input data (including data from the first and second communication modules) can be processed by the main central processing unit (CPU) of the main control board 131, including whether to segment the data and select an appropriate scenario for data transmission.

[0085] The main control board enables unified decision-making and processing of data, facilitating data management and control of the communication module.

[0086] Optionally, such as Figure 1 As shown, the main control unit 13 further includes at least one of the following:

[0087] The optical module 134 is connected to the main control board 131 and is used to convert the received optical signal into a data format that is compatible with the first communication module 11 and / or the second communication module 12.

[0088] The data storage unit 135 is connected to the main control board 131 and is used to store received data and / or data to be sent.

[0089] like Figure 1 As shown, the main control unit 13 also includes an optical module 134, which is connected to the main control board 131 and also connected to the airborne data input interface 136. The optical module is used to receive the optical signal input from the airborne data input interface and convert the optical signal into data of the corresponding format, so that the converted data can be received by the first communication module and the second communication module. The optical module 134 transmits the converted data to the main control board 131 for processing, such as storage or transmission to the communication module.

[0090] The main control unit 13 may further include a data storage unit 135 for storing data to be sent and received. The data storage unit 135 is connected to the main control board 131, which is used to decide whether to store or send the received data.

[0091] When the signals of the first communication module 11 and the second communication module 12 are poor, the main control unit can control the data storage, which improves the flexibility of data processing.

[0092] Optionally, the main control unit 13 further includes a power management module 137, which is connected to the first communication module 11 via a first connector 132 and to the second communication module 12 via a second connector 133, such as... Figure 3 As shown, the power management module 137 includes at least one of the following:

[0093] Power filter module 1371;

[0094] 1372 step-down module;

[0095] Surge protection module 1373;

[0096] Reverse connection protection module 1374.

[0097] The power management module 137 is connected to the first communication module 11 via a first connector (such as a board-to-board connector) and to the second communication module via a second connector (such as a board-to-board connector).

[0098] Since the power supply for the airborne 5G terminal comes from the aircraft's connector, it needs to meet the hot-swappable requirements, requiring a reliable power protection module and a step-down module.

[0099] Among them, the power supply filter module 1371, also known as the aviation electromagnetic interference (EMI) / electromagnetic compatibility (EMC) module, is used for filtering.

[0100] The two step-down modules 1372, also known as aviation DC-DC modules, are used for high-voltage to low-voltage conversion.

[0101] Surge protection module 1373 is used for surge protection.

[0102] The reverse connection protection module 1374 includes a reverse connection protection diode for preventing reverse connection.

[0103] The power management module 137 mainly filters and regulates the DC36V airborne power supply from the external connector, and converts it to 4V through a step-down module to supply the power required by the entire communication subsystem, ensuring the high reliability of the entire power supply system.

[0104] Currently, the mainstream power output of civil aircraft includes 115VAC / 400Hz, which is filtered by the EMI module's filter circuit, converted to 36VDC power by the AD / DC module, and then output as 5~12VDC by the DC / DC module's circuit.

[0105] For small aircraft, helicopters, drones, etc., a 36V DC system is generally used. In order to achieve stable and safe power supply under airborne power supply conditions and to prevent damage to equipment under surge conditions, the 36V DC power supply is directly stepped down and rectified to supply power to the main and auxiliary modules.

[0106] Optionally, the airborne terminal further includes a first antenna 111, which is connected to the first communication module 11 via a radio frequency conversion unit 14. The first communication module 11 is used to receive the first network signal through the first antenna 111.

[0107] The airborne terminal also includes a second antenna 121, which is connected to the second communication module 12 via the radio frequency conversion unit 14. The second communication module 12 is used to receive the second network signal through the second antenna 121.

[0108] The airborne 5G terminal has network management capabilities, supports file transfer protocols, can resume interrupted downloads, supports online upgrades, and can report its working status. The module is connected to the 5G network via RF cables and a 5G antenna to realize data transmission from the airborne equipment to the ground.

[0109] The airborne antenna includes a first antenna and a second antenna. The first antenna is connected to the first communication module via a radio frequency conversion unit, and the second antenna is connected to the second communication module via a radio frequency conversion unit.

[0110] When the main control unit 13 controls the first communication module 11 to turn on and receive signals, the first communication module 11 receives the first network signal through the first antenna 111; when the main control unit 13 controls the second communication module 12 to turn on and receive network signals, the second communication module 12 receives the second network signal through the second antenna 121.

[0111] The main control unit 13 can flexibly control the corresponding communication module to receive network signals through the antenna, which can improve the convenience and efficiency of operation and improve the stability of network connection.

[0112] Optionally, the first antenna 111 is an airborne omnidirectional antenna, and the second antenna 121 is an airborne phased array antenna.

[0113] Among them, airborne omnidirectional antennas are generally in the form of blade-shaped or disc-shaped antennas.

[0114] To allow for flexibility in antenna placement, the first antenna (omnidirectional antenna) and the second antenna (phased array antenna) at the far end are designed to transmit back to the two communication modules via optical fibers. After transmission, the optical fiber and radio frequency are converted by the radio frequency conversion unit (also known as the antenna switching unit) 14.

[0115] The first communication module 11 and the second communication module 12 of the airborne 5G are responsible for the transmission, reception and processing of corresponding radio frequency signals, respectively. The main components include a modem for signal processing, a multi-antenna radio frequency transceiver, an interface processing unit, a power supply module, etc.

[0116] like Figure 4 As shown, the radio frequency conversion unit 14 includes a radio frequency interface, an optical fiber interface, a radio frequency / optical switching matrix / radio frequency to optical conversion module, and a power module. The optical fiber interface is connected to the optical fiber interfaces of the phased array antenna and the omnidirectional antenna, respectively. The radio frequency to optical conversion module is responsible for converting the radio frequency signal into an optical signal and transmitting it to the 5G ATG CPE for radio frequency signal modulation and demodulation.

[0117] A schematic diagram of the cross-linking between the airborne antenna and the antenna switching unit, and the airborne CPE unit is shown below. Figure 4 As shown.

[0118] Optionally, the flight equipment is any one of an airplane, an electric vertical takeoff and landing (eVTOL) aircraft, or an unmanned aerial vehicle (UAV).

[0119] The first antenna is respectively installed on the belly and / or top of the flight equipment;

[0120] The second antenna is mounted on the belly of the flight equipment.

[0121] The first antenna (such as an omnidirectional antenna) connecting the first communication module includes two antennas, and the second antenna (such as an ATG dedicated phased array antenna) connecting the second communication module includes one antenna.

[0122] Taking an airplane as an example, such as Figure 5 and Figure 6 As shown, Figure 5 (The bottom view of the aircraft) is a schematic diagram of the antenna distribution on the aircraft's belly. Figure 6 (Top view of the aircraft) is a schematic diagram of the antenna distribution on the aircraft's fuselage. The first antenna is installed in two locations: the belly and the top (also known as the fuselage back). The first communication module is connected to the first antenna; as shown... Figure 5 As shown, the second antenna is installed on the belly of the aircraft, and the second communication module is connected to the second antenna.

[0123] The first communication module typically operates at ground level (0 altitude) or low altitude (e.g., below 1000 meters). At low altitude, it is designed to receive 5G signals from ground base stations via the first antenna mounted on the fuselage. When the aircraft lands on the ground (0 altitude), it is designed to receive 5G signals from ground base stations via the first antenna mounted on the back of the aircraft.

[0124] The second communication module typically operates in high-altitude, high-speed scenarios. Therefore, the second antenna is designed to be installed on the belly of the aircraft to better receive the airborne signal coverage from the ground ATG base station and to perform beamforming.

[0125] Antennas can be used in the following scenarios:

[0126] Scenario 1: Ground and low altitude

[0127] The aircraft can access the terrestrial 5G network normally in both situations: when it is on the ground (at an altitude of 0 meters) and at a low flight altitude (e.g., below 1000 meters). In these cases, the main module (i.e., the first communication module) is used for data transmission. The main control unit can determine the real-time status of the aircraft by receiving GPS altitude and information from the airborne bus. At this time, the main module is activated. When the flight altitude is low (e.g., 0-1000 meters), the main module uses the first antenna for data services. When the aircraft is at an altitude of 0 meters, the data channel of the first antenna on the fuselage is simultaneously activated, working together with the first antenna on the belly of the aircraft.

[0128] Scene 2: High-altitude scene

[0129] When an aircraft flies at a high altitude (e.g., above 1000 meters), the speed of a commercial airliner is generally greater than 300 km / h. Furthermore, at altitudes above 1000 meters, ground-based 5G network signals are often cluttered, lacking a primary serving cell, resulting in severe handover issues and frequent dropped connections. Therefore, in this scenario, the main control unit shuts down the main module (first communication module) and activates the secondary module (second communication module) for data connection. The secondary module uses the second antenna on the fuselage to access the ATG network for data transmission.

[0130] The antenna distribution on the belly of the aircraft is as follows Figure 5 As shown, the antenna distribution on the back of the aircraft is as follows: Figure 6 As shown.

[0131] Cell selection and neighbor cell handover for the primary and secondary modules of the airborne terminal can be determined based on the measured Reference Signal Received Power (RSRP) level. When the airborne terminal is on the ground, it can access the network normally according to the normal cell selection and handover strategy. When in flight, further optimization is needed to adapt to the low-altitude and high-altitude wireless network environments. Specifically, the following strategy can be implemented:

[0132] 1. The main control unit determines the real-time flight altitude of the aircraft. When flying at low altitude (e.g., altitude less than or equal to 1000 meters), it switches the communication module by switching the frequency threshold, activating the measurement threshold, and deactivating the measurement threshold.

[0133] 2. When at high altitudes (e.g., above 1000 meters), the main module is shut down and the secondary module is used for data transmission. The communication module is switched according to the thresholds mentioned above.

[0134] In some optional implementations, the first communication module and the second communication module can also be connected to the BeiDou / Global Positioning System (GPS) to obtain timing information and ensure time synchronization with the ground base station.

[0135] In some alternative implementations, data is acquired through an airborne data interface, and real-time GPS information from the airborne bus is obtained through data parsing to obtain a standard time, which can then be synchronized with the ground base station.

[0136] Optionally, such as Figure 1 As shown, the airborne terminal further includes at least one of the following:

[0137] At least one of a first power amplifier 112 and a second power amplifier 122, wherein the radio frequency conversion unit 14 is connected to the first communication module 11 through the first power amplifier 112, and the radio frequency conversion unit 14 is connected to the second communication module 12 through the second power amplifier 122;

[0138] At least one of a first GPS antenna 113 and a second GPS antenna 123, wherein the first GPS antenna 113 is connected to the first communication module 11 and the second GPS antenna 123 is connected to the second communication module 12.

[0139] like Figure 1 As shown, the first communication module 11 can be connected to the radio frequency conversion unit 14 through the first power amplifier 112, and the second communication module 12 can be connected to the radio frequency conversion unit 14 through the second power amplifier 122, thereby improving the acquired signal strength.

[0140] The GPS antenna can also be replaced with a BeiDou antenna.

[0141] Optionally, the main control unit 13 is used to control the first communication module 11 to turn on and receive the first network signal according to the flight parameters of the flight equipment, and / or to control the second communication module 12 to turn on and receive the second network signal.

[0142] Optionally, the flight parameters include at least one of flight speed and flight altitude.

[0143] The main control unit 13 controls the opening and closing of the first communication module 11 and the second communication module 12 based on parameters such as the flight speed and altitude of the flight equipment.

[0144] For example, when a low altitude and slow speed are detected, the first communication module can be activated to receive the first network signal; when a high altitude and fast speed are detected, the first communication module can be deactivated and the second communication module activated to receive the second network signal. During the switch from the first to the second communication module, the quality of the network signals connected to both modules can be assessed to achieve seamless network switching and improve network connection stability.

[0145] The 5G airborne terminal of this application includes a main control unit 13, a 5G main module (i.e., the first communication module) 11, a 5G sub-module (i.e., the second communication module) 12, a power management module, and LED indicator lights. The power management module and communication module of the main control unit are connected and communicate with the 5G main module and the 5G sub-module through board-to-board connectors, respectively.

[0146] The main control unit 13 integrates a data receiving unit, a 5G communication module, a data relay unit, and some IO control circuits; the power management module includes a power protection and filtering module and a power step-down module.

[0147] The 5G main module communicates with the outside world and receives service data streams from the main control board via board-to-board connectors. The 5G main module is also connected to the power module board via board-to-board connectors, and while receiving input power, it provides some interface signals to the power module board and the sub-module.

[0148] The power management module has a 32-pin connector for receiving an external 36V DC input voltage and performing a step-down conversion. Internally, it connects to the main module and the sub-module via board-to-board connectors, providing them with the necessary power.

[0149] The 5G sub-module is connected to the power management module via a board-to-board connector to receive input voltage and bus signals.

[0150] The airborne terminal adopts a dual 5G module solution. The front end connects to the airborne avionics bus or other airborne data source servers or switches to obtain data input. To simplify the air interface design and reduce the difficulty of airborne antenna modification, if the system only operates in the 4.9GHz frequency band, the two modules share a single antenna through an RF combiner, and the operating status of the main and auxiliary modules is controlled and switched by the control unit. If the two modules operate on different frequencies, they transmit and receive wirelessly through independent antennas, and the overall operation is controlled and selected by the main control unit.

[0151] See Figure 7 , Figure 7 This application provides a network connection method applied to an airborne terminal as described in any of the above embodiments. The airborne terminal includes a first communication module, a second communication module, and a main control unit. The first communication module is used to receive a first network signal, and the second communication module is used to receive a second network signal. The method includes:

[0152] Step 701: Obtain the flight parameters of the flight equipment through the main control unit;

[0153] Step 702: When the flight parameters are within the first parameter range, control the first communication module to be in the on state and control the second communication module to be in the off state.

[0154] Step 703: When the flight parameters are within the range of the second parameter, control both the first communication module and the second communication module to be in the on state;

[0155] Step 704: When the flight parameters are within the range of the third parameter, control the first communication module to be in the off state and control the second communication module to be in the on state.

[0156] The airborne terminal includes a first communication module and a second communication module. The main control unit acquires the flight parameters of the flight equipment (such as an airplane, a drone, etc.) and controls the opening and closing of the first and second communication modules based on the flight parameters.

[0157] The main control unit's software design can utilize an embedded Linux operating system. The business systems include:

[0158] (1) Data processing unit

[0159] It provides data input and format conversion processing functions for various airborne input interfaces, including the ARNIC429 digital information transmission system, the Controller Area Network (CAN) bus, the ARNIC664 bus, and other bus data interfaces.

[0160] (2) Logic processing unit

[0161] The communication channel logic of the control communication module is judged and selected based on flight parameters (including flight altitude (e.g., a judgment threshold of 1000 meters) and flight speed (e.g., a judgment threshold of 500 km / h)) and the wireless channel quality of the two communication modules, to select the optimal communication network to camp on and transmit data. When there is no signal on either the standard 5G or 5G ATG network, the data is buffered and prioritized. After the network is restored, the data is transmitted according to the priority order.

[0162] (3) Management Unit

[0163] It provides external management interfaces and a management interface to enable the configuration of the two communication modules, modification and reset of business logic, and firmware over-the-air (OTA) upgrades.

[0164] (4) Data conversion and processing unit

[0165] It is responsible for performing unified format conversion on the airborne bus data, and the converted data is sent to the main control board and logic processing unit for corresponding storage and application.

[0166] To improve the network connection efficiency of the dual-mode module and enable it to operate in a suitable network mode, a network connection and data processing workflow is adopted. The main control board serves as the control unit, and intelligently selects the best network to connect to based on the network connection status, thereby improving its network connection efficiency.

[0167] (5) Dual-module workflow

[0168] After the system starts up, the main control unit obtains the aircraft's real-time flight parameters from the aircraft bus, the first and second communication modules are initialized, and network connection status information is obtained. The main control unit determines which network channel to use for data transmission based on the flight parameters and network connection status information.

[0169] The flight parameters may include flight speed, flight altitude, and other parameters that affect the network signal. The first network signal is a network signal used for ground communication, and the second network signal is a network signal of the air-to-ground (ATG) network.

[0170] When the flight parameters are within the first parameter range (e.g., altitude is 0 or low altitude range), the flight equipment is at a low altitude. When the first communication module is activated to connect to the 5G network, it can be in flight mode or stationary mode.

[0171] When the flight parameters are within the second parameter range (e.g., low flight altitude and slow speed), the first communication module and the second communication module are activated.

[0172] When the flight parameters are within the range of the third parameter (e.g., high flight altitude and high speed), the first communication module is turned off, while the second communication module remains on.

[0173] Taking an airplane as an example, as the airplane gradually takes off from the ground, the main control unit acquires the airplane's flight parameters. When the flight altitude is low, only the first communication module is activated to connect to the 5G network; as the flight altitude gradually increases, the second communication module is activated simultaneously, and both communication modules remain active; when the flight altitude is high or the speed is high, the first communication module is deactivated, the second communication module is activated, and the second communication module is used to connect to the ATG network.

[0174] The main control unit controls the opening and closing of the first and second communication modules according to flight parameters, enabling the flight equipment to connect to the corresponding network under flight parameter conditions and switch networks when flight parameters change, thereby improving the continuity and stability of network connection.

[0175] Optionally, the flight parameters include at least one of flight altitude and flight speed;

[0176] The first parameter range is: the flight altitude is 0 and the flight speed is less than the first speed;

[0177] The range of the second parameter is: the flight altitude is greater than 0 and less than the first altitude, and the flight speed is less than the first speed;

[0178] The range of the third parameter is: the flight speed is greater than the first speed and / or the flight altitude is greater than the first altitude.

[0179] The first speed is, for example, 500 km / h; the first altitude is, for example, 1000 meters.

[0180] The main control unit acquires flight parameter information of the flight equipment and controls the opening and closing status of the two modules based on the flight parameters.

[0181] For ease of understanding, specific implementation methods are given as examples below.

[0182] For example, such as Figure 8 As shown, the main control unit acquires the aircraft bus status parameters (i.e., flight parameters), and the main and auxiliary modules initialize and acquire network access information. The main control unit determines the network that needs to be activated based on the flight parameters.

[0183] When the flight speed of the flight equipment is less than 500 km / h and the flight altitude is less than 1000 meters, if the first communication module (i.e. the main module) is connected to the network, the data transmission channel of the main module is activated, and the system performs data communication services through the first communication module.

[0184] In addition, when the first communication module is activated, the second communication module (also known as the sub-module) can be activated simultaneously to split the data flow (without affecting the data transmission of the first communication module). That is, the main and sub-modules transmit data at the same time, thereby improving the system's wireless throughput.

[0185] When the flight speed of the flight equipment is greater than 500 km / h or the flight altitude is greater than 1000 meters, if the second communication module (i.e., the sub-module) is connected to the ATG network, the data transmission channel of the sub-module will be activated, and data communication services will be carried out through the second communication module.

[0186] Optionally, the method further includes:

[0187] When the first communication module is in the enabled state, a first signal quality parameter of the first network signal received by the first communication module is detected, and the first communication module is switched to the second communication module according to the first signal quality parameter and the signal parameter threshold of the first communication module; and / or,

[0188] When the second communication module is in the enabled state, the second signal quality parameter of the second network signal received by the second communication module is detected, and the second communication module is switched to the first communication module according to the second signal quality parameter and the signal parameter threshold of the second communication module.

[0189] When the flight equipment is in flight (including scenarios of ascending from takeoff altitude and descending from landing altitude), the communication module of the airborne terminal can include the following states:

[0190] The first communication module is in the on state, and the second communication module is in the off state;

[0191] Both the first and second communication modules are in the ON state;

[0192] The first communication module is in the off state, and the second communication module is in the on state.

[0193] When the first or second communication module is in the active state, in order to obtain a better network, the main control unit switches the network connection between the two communication modules according to RSRP (i.e., the first signal quality parameter) and signal parameter thresholds (including at least one of the start measurement threshold, frequency cut-off threshold and stop measurement threshold).

[0194] The following are two specific application scenarios as examples.

[0195] Scenario 1: When the flight altitude is lower than the first altitude, network switching is performed between the first and second communication modules.

[0196] When the first communication module is used for data transmission, if the RSRP corresponding to the first communication module reaches the start measurement threshold, the measurement of the RSRP corresponding to the second communication module will be started.

[0197] If the RSRP corresponding to the first communication module reaches the frequency cut-off threshold, the first communication module is switched to the second communication module, that is, the second communication module is used for network transmission; if the RSRP corresponding to the first communication module reaches the shutdown measurement threshold, the measurement of the RSRP corresponding to the second communication module is turned off.

[0198] The first communication module takes frequency bands N41 and N28 as examples. The frequency cut-off threshold of frequency band N41 is -97dBm, the start measurement threshold is -92dBm, and the stop measurement threshold is -87dBm.

[0199] Frequency band N28 frequency cut-off threshold: -93dBm, start measurement threshold: -90dBm, stop measurement threshold: -88dBm.

[0200] When the second communication module is used for network transmission, if the RSRP of the second communication module reaches the start measurement threshold, the RSRP measurement of the first communication module will be initiated. If the RSRP of the first communication module reaches the frequency cut-off threshold, the second communication module will be switched to the first communication module, i.e., the first communication module will be used for network transmission; if the RSRP of the first communication module reaches the stop measurement threshold, the RSRP measurement will be stopped.

[0201] For example, the second communication module uses frequency band N79: frequency cut-off threshold: -99dBm, measurement start threshold: -94dBm, measurement stop threshold: -89dBm, same frequency switching threshold: 3dBm.

[0202] Scenario 2: When the flight altitude is greater than the first altitude, the first communication module is turned off and the second communication module is enabled for data transmission. For details on the implementation method, please refer to the above description.

[0203] For example, the second communication module uses frequency band N79: frequency cut-off threshold: -99dBm, measurement start threshold: -94dBm, measurement stop threshold: -89dBm, same frequency switching threshold: 3dBm.

[0204] With the rapid development of the low-altitude economy and the demand for high-altitude internet from commercial flights and general aviation, the demand for 5G network access for aircraft at altitudes from 0 meters to 12,000 meters is increasing. The scale of airborne 5G modules in electric vertical take-off and landing (eVTOL) aircraft, drones, manned general aviation aircraft, and commercial airliners is gradually growing. However, the continuity and stability of the network connection of the current ground standard 5G network and its supporting commercial 5G modules are difficult to meet the network connection requirements.

[0205] To meet the requirements of aircraft flying from 0 meters above ground to a maximum altitude of 12,000 meters and supporting a maximum flight speed of 1,200 km / h, this application adopts a dual-module design. The main control unit controls the opening and closing status of the main and auxiliary modules according to the flight parameters of the flight equipment, which can improve the continuity and stability of network connectivity.
