The embodiment of the application can acquire and process the related data based on the wireless and mobile communication technology. Wherein,,
the air-to-ground communication control method and device, the electronic device and the storage medium according to the embodiments of the present application will be described in detail below.
Fig. 1 is a schematic diagram of an implementation environment according to the present application, which can be regarded as related content devices involved in communication during a fixed-line flight of an aircraft, specifically, the implementation environment includes a server 101, an ATG base station 102, an ATG terminal 103 located on the aircraft, a ground communication base station 104, and a ground communication terminal 105; the ATG base station 102 and the ATG terminal 103 located on the aircraft form an ATG system, and data transmission can be performed between the ATG base station 102 and the ATG terminal 103 to provide communication service for the ATG terminal 103; the ground communication base station 104 and the ground communication terminal 105 form a ground communication system, data transmission can be performed between the ground communication base station 104 and the ground communication terminal 105, communication service is provided for the ground communication terminal 105, and the ground communication base station 104 can be a base station such as an IMT base station (International Mobile Telecommunications, ground cellular mobile) which provides service for ground equipment; and the server 101 is communicably connected to the ATG base station 102, the ATG terminal 103, the ground communication base station 104, and the ground communication terminal 105, respectively.
Of course, the number of ATG base stations 102, ATG terminals 103 located on board the aircraft, ground communication base stations 104, and ground communication terminals 105 shown in FIG. 1 is illustrative, and other numbers of devices are possible at other times, such as ATG systems in different airlines for different aircraft being different from ground communication systems.
The ATG system and the ground communication system use the same frequency for communication, because the ATG system and the ground communication system adopt the same frequency networking, interference signals can be generated between the ATG system and the ground communication system to influence the communication performance of the ATG system and the ground communication system.
Illustratively, when the ATG terminal 103 transmits an uplink signal from the aircraft to the ground-facing ATG base station 102, the same-frequency interference signal will be generated for the uplink of the ground communication base station, and since the coverage area of the ATG terminal 103 when transmitting a signal to the ground is very large, a large number of ground communication base stations in the air line will receive the ATG terminal 103 interference signal; meanwhile, the ground communication base station 104 transmits downlink signals upwards due to side lobes on antennas, the upper side lobe of each ground communication base station antenna is inconsistent, the loss of an empty transmission link is small, a large number of ground communication base stations 104 generate interference to the downlink of the ATG base station 102 by using downlink co-channel signals transmitted in empty, and even a large number of lumped strong interference areas where downlink signals of the ground communication base stations are overlapped are formed in a partial airspace.
The server 101 stores the uplink target interference position and the downlink target interference position of the aircraft on the airlines, and when the aircraft runs on the corresponding airlines, if the aircraft reaches the uplink target interference position or the downlink target interference position, the server 101 acquires service data of the ground communication system, so as to adjust the transmitting power of the ATG system according to the acquired service data of the ground communication system, thereby reducing the same-frequency interference at the corresponding positions.
The ATG terminal 103 and the ground communication terminal 105 may be any electronic device capable of realizing data visualization, such as a smart phone, a tablet, a notebook computer, and a computer, which is not limited herein. The server 101 is a communication management system, which may be an independent physical server, or may be a server cluster or a distributed system formed by a plurality of physical servers, where a plurality of servers may form a blockchain, and the servers are nodes on the blockchain, and the server 101 may also be a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (Content Delivery Network, content distribution networks), and basic cloud computing services such as big data and artificial intelligence platforms, which are not limited in this respect. The ATG base station 102 and the ground communication base station 104 are interface devices for providing access to the internet for the ATG terminal 103 and the ground communication terminal 105, which is not limited in this regard.
Fig. 2 is a flowchart illustrating a space-to-ground communication control method according to an exemplary embodiment. The air-to-ground communication control method may be applied to the implementation environment shown in fig. 1 and specifically executed by the server 101 in the implementation environment, and it should be understood that the method may also be applied to other exemplary implementation environments and specifically executed by devices in other implementation environments, and the implementation environment to which the method is applied is not limited by the embodiment.
As shown in fig. 2, in an exemplary embodiment, the method may include steps S210 to S250, which are described in detail as follows:
step S210: when the ATG system and the ground communication system are in the same-frequency networking, the interference signal strength between the ATG system and the ground communication system of the aircraft at different route positions is acquired based on the route of the aircraft.
The air-to-ground communication control method in the embodiment is applied to a scene that an ATG system and a ground communication system provide communication services for the same-frequency networking.
The aircraft basically flies according to a specified fixed air route, and the ground ATG base station and the ground communication base station are fixed in position, so that the interference signal strength between the ATG system and the ground communication system can be obtained when the aircraft is at different positions of different routes.
In this embodiment, when the ATG system and the ground communication system adopt the same broadband frequency networking, the signal interference has a larger influence on an uplink interference signal generated by the ATG system to the ground communication system, and the ground communication system generates a downlink interference signal to the ATG system.
Referring to fig. 3 specifically, when an ATG terminal transmits an uplink signal from an aircraft to an ATG base station on the ground, the ATG terminal will generate an co-channel interference signal for the uplink of the ground communication base station, and because the coverage area range is very large when the ATG terminal transmits a signal to the ground, a large number of ground communication base stations will receive the ATG terminal interference signal, thereby affecting the communication performance of the ground communication system; the ground communication base station transmits downlink signals upwards by virtue of the upper side lobes of the antennas of each ground communication base station, the upper side lobes of the antennas of each ground communication base station are inconsistent, the loss of an empty transmission link is small, a large number of downlink co-frequency signals which are empty to be transmitted by the ground communication base station can generate interference on the downlink of the ATG base station, and even a large number of lumped strong interference areas, namely downlink interference signal positions, where the downlink signals of the ground communication base station are overlapped are formed in a part of airspace, so that the communication performance of an ATG system can be influenced when an aircraft is positioned at the downlink interference signal positions.
Therefore, in this embodiment, only the uplink interference intensity information interference signal intensity generated by the ATG system to the ground communication system is collected when the interference signal is collected by the server 101, and the downlink interference intensity information interference signal intensity generated by the ground communication system to the ATG system is specifically collected, which is specifically the uplink interference signal intensity caused by the ATG terminal on the aircraft to the uplink signal emitted by the ground and the downlink interference signal intensity generated by the ground communication base station when the aircraft is located at the downlink interference signal position.
Step S230: and determining the route position with the interference signal intensity larger than a preset interference intensity threshold value as a target interference position.
In this embodiment, after the uplink interference signal strength and the downlink interference signal strength of the aircraft at different positions are obtained, the signal strength of some interference signals is smaller, and the influence on the ATG system or the ground communication system is not great, so that the positions with smaller interference signal strengths can not be controlled; when some interference signals with high intensity affect the base stations in the interference signal area, the ATG system needs to be adjusted when the aircraft is at the position to reduce the signal intensity of the interference signals.
In this embodiment, for the interference signal intensities of different positions, it may be determined whether the interference signal intensity may cause a communication influence on the ATG system and the ground communication system in the area where the interference signal is located by presetting an interference intensity threshold, if the communication influence is caused to be larger, determining the flight chess position corresponding to the interference signal as the target interference position, where the target interference position includes flight altitude information of the aircraft and position information of the aircraft, when the aircraft is located at the target interference position, it is proved that the interference signal at the position is larger, communication control needs to be performed, and then specific communication control may be performed according to whether the interference signal intensity is larger for uplink interference signal or larger for downlink interference signal intensity.
The setting of the interference intensity threshold may be set according to an empirical parameter in practical application, or may be set according to a user's requirement, which is not particularly limited herein.
Of course, since the uplink interference signal strength and the downlink interference signal strength are different, the uplink interference strength threshold and the downlink interference strength threshold may be set based on the definitions of the uplink interference signal and the downlink interference signal, respectively, so that the uplink target interference position and the downlink target interference position may be obtained correspondingly.
In this embodiment, the target interference position is a route position, but in practical application, the target interference position may also include flight altitude information of the aircraft and position information of the aircraft, so that the aircraft can be positioned, and whether the aircraft reaches the target interference position can be confirmed. The uplink target interference position indicates that the strength of the uplink interference signal received is high when the aircraft is located at the uplink target interference position, and the downlink target interference position indicates that the strength of the downlink interference signal received is high when the aircraft is located at the downlink target interference position.
Of course, for the same route, the uplink target interference position and the downlink target interference position are basically different, so the server can store the uplink target interference position and the downlink target interference position respectively, and then, when the aircraft flies along the route again, whether the aircraft flies to the uplink target interference position/the downlink target interference position which need to be controlled by communication can be determined from the stored target interference position information.
Step S250: and if the aircraft is positioned at the target interference position, acquiring service data of the ground communication system, and adjusting the transmitting power of the ATG system based on the service data.
In this embodiment, the server receives the position information of the aircraft while the aircraft is flying along the route, and compares the position information with the pre-stored target interference position, and if the aircraft reaches the target interference position, the transmitting power of the ATG system can be adjusted to reduce the interference signal.
Specifically, when the aircraft is located at the uplink target interference position, the strength of the uplink interference signal caused by the ATG terminal on the aircraft to the uplink signal transmitted on the ground is higher, and at this time, the transmitting power of the ATG terminal can be controlled, for example, the uplink transmitting power of the ATG terminal is reduced, so that the influence of the ATG system on the uplink of the ground communication system is reduced.
The uplink traffic load of the ground communication system determines the uplink interference that the ground communication base station can bear, when the ground communication system is in uplink traffic busy, the higher the ground communication base station bottom noise rise, the smaller the uplink co-channel interference that the ground communication base station can bear, when the ground communication system is in uplink traffic idle, the lower the ground communication base station bottom noise rise, the larger the uplink co-channel interference that the ground communication base station can bear. Therefore, referring to fig. 4, in controlling the uplink transmission power of the ATG terminal, the uplink transmission power of the ATG terminal needs to be adjusted in combination with the uplink traffic load of the ground communication system, if the uplink traffic load is larger, the amplitude of the uplink transmission power of the ATG terminal is reduced, and if the uplink traffic load is smaller, the amplitude of the uplink transmission power of the ATG terminal is reduced.
When the aircraft is located at the downlink target interference position, the ground communication base station forms downlink signal superposition at the downlink target interference position for the downlink signal to be transmitted, and at the moment, the transmitting power of the ATG base station can be controlled, for example, the downlink transmitting power of the ATG base station is increased, the receiving strength of the downlink signal of the ATG system is improved, the downlink communication performance of the ATG system is improved, and therefore the influence of the ground communication base station on the downlink of the ATG system is reduced.
The total interference magnitude obtained by the superposition of the downlink signals at the downlink target interference position is related to the traffic load of the ground communication system, when the ground communication system is in busy downlink traffic, i.e. the downlink traffic load is large, the superposition of the downlink signals at the downlink target interference position is large, and when the ground communication system is in idle downlink traffic, i.e. the downlink traffic load is small, the superposition of the downlink signals at the downlink target interference position is small. Therefore, referring to fig. 5, controlling the downlink transmission power of the ATG base station based on the downlink target interference position also needs to be adjusted in conjunction with the downlink service load of the ground communication system, if the downlink service load is larger, the magnitude of the downlink transmission power of the ATG base station is increased, and if the downlink service load is smaller, the magnitude of the downlink transmission power of the ATG base station is decreased.
In this embodiment, data of downlink traffic load and uplink traffic load of the ground communication system may be obtained by a wireless network management platform of the ground communication system, and when the downlink traffic load and the uplink traffic load are traffic load statistics information of the ground communication system that can cause signal interference to a corresponding target interference position when the aircraft is located at the corresponding target interference position.
In this embodiment, by acquiring and storing the target interference position with the higher uplink and downlink interference signal strength/uplink interference signal strength of the airlines, when the aircraft is located at the target interference position, the transmission power of the ATG terminal/ATG base station is adjusted in combination with the uplink traffic load/downlink traffic load corresponding to the ground communication system, thereby reducing the influence of the ATG system on the uplink of the ground communication system and improving the performance of the ATG downlink communication, and improving the communication performance of the ATG system and the ground communication system.

Step S610: and acquiring the uplink interference signal strength caused by the ATG terminal on the aircraft on the uplink signals emitted to the ground based on the different route positions of the aircraft.
In this embodiment, the uplink interference signal strength is the signal strength of the co-channel interference signal generated on the uplink of the ground communication base station when the ATG terminal transmits the uplink signal from the aircraft to the ground ATG base station, and based on this, the uplink interference signal strength at the corresponding position can be obtained when the aircraft is located at different route positions.
Step S630: and obtaining the downlink interference signal position of the downlink signal overlapped with the downlink signal formed in the space domain according to the downlink signal transmitted by the ground communication base station.
In this embodiment, the ground communication base station forms a large number of lumped strong interference areas where the downlink signals of the ground communication base station are overlapped in the partial airspace by the downlink common-frequency signals of the ground communication base station, and the area where the lumped strong interference areas are overlapped on the air route is determined as the position of the downlink interference signal, that is, the position of the downlink interference signal is not only the lumped strong interference area overlapped by the ground communication base station, but also the area where the aircraft passes when flying along the air route.
Step S650: and acquiring the strength of the downlink interference signal generated by the ground communication base station when the aircraft is positioned at the position of the downlink interference signal.
When the position of the downlink interference signal is determined, the strength of the downlink interference signal generated by the ground communication base station at the position can be determined, namely the signal strength after the ground communication base station overlaps the idle downlink co-frequency signal at the position of the downlink interference signal.

When the aircraft is positioned at the uplink target interference position, the uplink service load of the ground communication system at the moment can be collected, then the target uplink service level of the aircraft is determined according to the uplink service load, and the communication control is carried out according to the uplink interference bearing threshold value in the target uplink service level.

Step S730: and reducing the uplink transmitting power of the ATG terminal based on the uplink interference bearing threshold corresponding to the target uplink service level, so that the uplink interference intensity value born by the ground communication system is smaller than the corresponding uplink interference bearing threshold.
In this embodiment, when controlling the uplink transmission power of the ATG terminal, the control is performed based on the uplink interference tolerance threshold corresponding to the target uplink traffic level, specifically, if the corresponding uplink interference tolerance threshold is smaller, the amplitude of the uplink transmission power of the ATG terminal is reduced, and if the corresponding uplink interference tolerance threshold is larger, the amplitude of the uplink transmission power of the ATG terminal is reduced. Of course, the uplink interference signal caused by the ATG terminal to the ground communication system at this time may also be detected when the uplink transmission power of the ATG terminal is reduced until the signal strength of the uplink interference signal caused by the ATG terminal to the ground communication system is less than the uplink interference tolerance threshold.
In this embodiment, by setting the uplink traffic load level, different control modes are implemented on the uplink transmission power of the ATG terminal based on the conditions of different traffic load amounts, so as to realize accurate control on the ATG terminal, so as to accurately reduce signal interference on the ground communication system and improve the signal quality of the ground communication system.

step S810: and determining a target downlink service level of the downlink service load from a plurality of preset downlink service load levels according to the downlink service load.
In this embodiment, for the downlink traffic load value of the ground system, a plurality of downlink traffic load levels may be set, and for each downlink traffic load level, the downlink interference strength of the ground communication system is set, and the greater the downlink traffic load level, the greater the corresponding downlink traffic load, the greater the interference signal strength caused to the downlink target interference location, that is, the greater the set interference signal strength threshold.
When the aircraft is positioned at the downlink target interference position, the downlink service load of the ground communication system at the moment can be collected, then the target downlink service level of the aircraft is determined according to the downlink service load, and the communication control is performed according to the downlink interference intensity threshold value in the target downlink service level.
In this embodiment, when the aircraft is located at the downlink target interference position, the collected downlink traffic load of the ground communication system is the downlink traffic load in the ground communication base station that generates the downlink interference signal for the downlink target interference position, if the downlink interference signal b of the downlink target interference position a is obtained by stacking downlink signals of the ground communication base stations c, d and f when the aircraft is located at the downlink target interference position a, the collected downlink traffic load data is the data set of the downlink traffic load of the ground communication base stations c, d and f.
Step S830: and increasing the downlink transmitting power of the ATG base station based on the downlink interference intensity threshold corresponding to the target downlink service level.
In this embodiment, when controlling the downlink transmission power of the ATG base station, the control is performed based on the downlink interference strength threshold corresponding to the target downlink service level, specifically, if the corresponding downlink interference strength threshold is smaller, it is proved that the strength of the downlink interference signal is smaller, so that the smaller the amplitude of the transmission power of the ATG base station is increased, and if the corresponding downlink interference strength threshold is larger, the larger the amplitude of the downlink transmission power of the ATG base station is increased.
In this embodiment, by setting the downlink traffic load level, different control modes can be implemented on the downlink transmission power of the ATG base station under the condition of different traffic load amounts, so as to realize accurate control on the ATG base station, so as to accurately reduce signal interference on the ATG system and improve signal quality of the ATG system.
