[0025] The embodiments of the present invention provide a helicopter airborne base station device based on satellite links, Figure 1 This is a schematic diagram of the helicopter airborne base station device based on satellite links provided in the embodiments of the present invention. As Figure 1 shown, it includes:

[0026] A portable workstation 101 is used to control the helicopter-borne base station device to start working in the emergency area in an emergency scenario, receive user communication data in the emergency area, transmit and receive user communication data via satellite, connect to the network of the mobile network operator, provide mobile network coverage for the emergency area, and adjust the coverage range of the airborne satellite antenna according to the calculation results after calculating the link and spatial angles.

[0027] An airborne satellite antenna 102 is used to modulate, demodulate, transmit and receive satellite signals in the helicopter-borne environment.

[0028] The helicopter-borne base station device based on satellite link proposed in the embodiment of the present invention transmits user communication data via satellite in the emergency area, connects to the network of the network operator, adjusts the coverage range of the airborne base station, effectively ensures that the helicopter can carry out emergency operations in extreme scenarios, and improves the emergency response ability.

[0029] In one embodiment, the portable workstation 101 includes:

[0030] A control unit is used to control the helicopter-borne base station device to fly above the emergency area after determining that the ground network is interrupted and start working at a preset altitude above the emergency area.

[0031] A communication unit is used to receive user communication data in the emergency area and transmit and receive user communication data via satellite.

[0032] A network recovery unit is used to connect to the network of the mobile network operator and provide mobile network coverage for the emergency area.

[0033] A device adjustment unit is used to adjust the coverage range of the airborne satellite antenna in motion according to the calculation results after calculating the link and spatial angles.

[0034] In one embodiment, the communication unit is specifically used for:

[0035] Connect to the user terminal on the ground, receive the user communication data of the user terminal, and transmit and receive user communication data via satellite.

[0036] In one embodiment, the network recovery unit includes:

[0037] A gateway station is used to connect the satellite and the ground network and connect to the network of the mobile network operator through the public network outlet.

[0038] In one embodiment, the device adjustment unit is specifically used for:

[0039] Adjust the coverage radius and transmission angle of each airborne satellite antenna in motion according to the calculation results.

[0040] Figure 2 This is an example diagram of the helicopter-borne base station device based on satellite link provided in the embodiment of the present invention, asFigure 2 As shown, in one example, the helicopter-borne base station device based on satellite links includes Zhongxing, a helicopter, an airborne satellite antenna, an airborne satellite modem, a satellite communication main station, and an emergency command center. At the same time, multiple personal terminals are set up at the ground emergency site.

[0041] During specific implementation, when the ground network is interrupted during a disaster, the helicopter carries satellite communication equipment and a public network 4G-LTE base station and flies over the emergency site. After determining the working area of the emergency rescue personnel, it hovers or stays in the airspace at a height of about 1000 meters, establishes a temporary air base station, covers the signal to the ground, and provides mobile network access services for ground personnel.

[0042] In one embodiment, the airborne mobile communication antenna 102 includes:

[0043] A modem for modulating digital signals into analog signals and demodulating analog signals into digital signals in the helicopter-borne environment;

[0044] Multiple airborne mobile communication antennas for receiving and transmitting satellite signals in the helicopter-borne environment.

[0045] The airborne station adopts a 0.4-meter Ka-band airborne mobile communication antenna (GA400-Ka). This airborne antenna integrates a built-in power amplifier and an optimized airborne modulation and demodulation modem, meeting the high-speed backhaul requirements of helicopter video, audio, images, and data under rotor occlusion. The weight of this satellite does not exceed 20 kg, and the size does not exceed 530 mm * 390 mm. Figure 3 This is a schematic diagram of the antenna installation provided in the embodiment of the present invention. For the installation of the LTE antenna assembly, see Figure 3 , and the LTE antenna is fixed to the skid position through the installation bracket of the upper and lower hoop. The total weight of the 4 LTE installation brackets is 1.5 kg.

[0046] In one embodiment, the airborne satellite antenna 102 further includes:

[0047] Multiple installation brackets, arranged in a diamond shape under the helicopter belly and fixed to the skid position, for fixing each airborne mobile communication antenna by means of upper and lower hoop.

[0048] In one embodiment, it further includes:

[0049] An emergency power supply for supplying power to each unit of the helicopter-borne base station device based on satellite links.

[0050] For example, a ground mobile user accesses an air-based base station for voice and data, and the data is transmitted through a high-throughput satellite link to a satellite gateway station, and then connected to the core network of a mobile network operator through a public network exit to achieve the remote mobile coverage ability of the mobile network. After calculating the link and spatial angles, the air-based base station will be configured with 4 antennas, and the theoretical radius of the ground horizontal coverage area can reach 1700 meters. This coverage range is related to the installation angle of the base station antenna. Figure 4 This is a schematic diagram of the signal coverage range provided in the embodiment of the present invention. The specific signal coverage range is as Figure 4 shown. During actual use, fine-tuning needs to be performed according to the theoretical angle. At the same time, the base station user carrying capacity is for more than 500 voice calls and data transmission requirements, realizing the rapid restoration of communication at the emergency site.

[0051] 1. Base station BBU

[0052] The BBU selects Huawei BBU3910 with UBBPe2 and UMPTb9 service boards to achieve wide-area coverage in the telecom band5 frequency band TX: 869 - 880 MHz, RX: 824 - 835 MHz or other frequency bands TX: 1765 - 1785 MHz, RX: 1860 - 1880 MHz. The shorter the wavelength, the higher the frequency of the wave, and the greater the penetration ability. The coverage range can reach 7.3 kilometers under ideal conditions.

[0053] 2. Base station RRU

[0054] The RRU selects RRU3653 with the number of channels: 2T4R, 2 * 80W.

[0055] 3. Base station antenna feeder

[0056] Since the antenna installation method of the aircraft is different from that on the ground, it flies above 1000 meters above the ground and emits signals vertically downward, and many factors are unpredictable. The antenna selects a customized model (the aerodynamic shape can be customized later), and the main lobe transceiver distance is about 4800 meters.
