Embodiment 1

[0024] refer to figure 1 As shown, in the embodiment of the present invention, the communication system includes an aircraft 10, multiple ground base stations 11, and core network equipment 12, there is a communication connection between the aircraft 10 and multiple ground base stations 11, and the ground base station 11 and the core There is a communication connection between network equipment 12; Wherein:

[0025] The aircraft 10 is configured to send data to the ground base station 11 and receive data sent by the ground base station 11; wherein, the frequency used by the aircraft 10 to send the data to the ground base station 11 is empty Ground frequency F' a2g ; The frequency used when the aircraft 10 receives the data sent by the ground base station 11 is the ground-to-air frequency F' g2a ; the F' a2g and the F' g2a are multiplexing frequencies, the F' a2g and the F' g2a Are not the same;

[0026] Each ground base station 11 is used to receive the data sent by the...

Embodiment 2

[0052] Based on the communication system described in the first embodiment above, when the first device and the second device are both satellites, the operating frequency used by the satellite to transmit the information from the ground to the air is recorded as The operating frequency used when the satellite transmits the information from the air to the ground is recorded as Aircraft 10 uses Send data to ground base station 11; And described ground base station 11 adopts Data is sent to the aircraft 10 .

[0053] Further, the antenna on the aircraft 10 is located below the aircraft, and the angle between the direction where the antenna transmits signals to the ground and the horizon line is greater than 2° (such as Figure 3b angle 2) to ensure that the data transmission between the ground base station 11 and the aircraft 10 will not interfere with the information transmission of the satellite.

Embodiment 3

[0055] Based on the communication system described in the first embodiment above, when the first device and the second device are both radio stations, the operating frequency used by the radio station to transmit information from the ground to the air is recorded as The operating frequency used by the station to transmit air-to-ground (and / or ground-to-ground) information is denoted as Aircraft 10 uses Send data to ground base station 11; And described ground base station 11 adopts Data is sent to the aircraft 10 .

[0056] Further, there is no overlapping area between the area covered by the transmission signal of the antenna on the ground base station 11 and the area covered by the transmission signal of the station, which ensures that the data transmitted by the ground base station 11 and the information transmitted by the station are consistent. will interfere with each other.

Abstract

The invention discloses a communication system and method. A plurality of ground base stations are arranged on the ground, The ground base stations and core network equipment jointly provide a communication network to aircrafts. Data transmission between the ground base stations and the aircrafts is realized by reverse reusing the working frequency of existing equipment. Since the ground base stations have the advantages of mature disposition technology, low disposition cost, and the bandwidth of the communication network provided by the ground base stations is wide, the communication cost of aircrafts can be effectively reduced, and the communication bandwidth used for aircraft data transmission is greatly increased. Since air-to-ground frequencies and ground-to-air frequencies are reuse frequencies, and the reuse frequencies are work frequencies of existing equipment, no new frequencies are assigned to the aircraft and ground base stations individually for information transmission, and only the work frequencies of existing equipment are reused. The problem that frequency spectrum resources are scarce is solved, and the utilization rate of the frequency spectrum resources is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication system and method. Background technique [0002] With the development of aviation and communication technology, the demand for broadband communication of aircraft is becoming more and more urgent, such as aircraft monitoring, aircraft health management, passenger aircraft security (video monitoring), and aircraft carrying users' Internet access, etc., all require the support of broadband communication systems. And in the various application scenarios mentioned above, the amount of communication data that the aircraft needs to transmit is huge. [0003] In traditional applications, airborne satellites are mainly installed in the aircraft, and the broadband provided by the airborne satellites is used to meet the communication needs of the aircraft. However, the traditional airborne satellite communication has the problems of high cost and narrow bandwidth, which ca...
