[0081] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field based on the present disclosure belong to the scope of protection of the present disclosure.

[0082] The embodiments of the present disclosure disclose an aviation mobile communication system, method, device, electronic device and medium, which are described below respectively.

[0083] The present disclosure provides an aviation mobile communication system. Figure 1 , Figure 1 A schematic diagram of an aeronautical mobile communication system according to an embodiment of the present disclosure includes:

[0084] An ATG terminal 110 and a plurality of ATG base stations 120; the signal frequency of the ATG terminal 110 is at least partially the same as the signal frequency of the IMT base station;

[0085] The ATG base station 120 is used to generate a measurement instruction for the target ATG terminal 110 when the target ATG terminal 110 of its own communication service needs to switch the ATG base station 120, and send the measurement instruction to the target ATG terminal 110;

[0086] The target ATG terminal 110 is used to obtain downlink signals of multiple ATG base stations 120 within the communication range based on the measurement instruction after receiving the measurement instruction, obtain the measurement result of each downlink signal, and send the measurement result of each downlink signal to the ATG base station 120 providing communication services to itself;

[0087] The ATG base station 120 is further used to receive the measurement results of each of the downlink signals, and obtain the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal 110 to each ATG base station 120; determine the target ATG base station 120 based on the measurement results of each of the downlink signals and the number of the IMT base stations, and send a base station switching instruction to the target ATG terminal 110, and send a service instruction for the target ATG terminal 110 to the target ATG base station 120;

[0088] The target ATG terminal 110 is used to send an uplink signal to the target ATG base station 120 after receiving the base station instruction;

[0089] The target ATG base station 120 is used to provide communication services for the target ATG terminal 110 after receiving an instruction to provide services for the target ATG terminal 110 .

[0090] In the present disclosure, the signal frequency of the ATG terminal is at least partially the same as the signal frequency of the IMT base station, that is, the ATG terminal in aeronautical mobile communications and the ground IMT base station can use the same frequency, so as to broaden the frequency bandwidth that the ATG terminal can use, thereby meeting the user's demand for aeronautical mobile service bandwidth. Moreover, when the target ATG terminal needs to switch the ATG base station, the ATG base station currently providing communication services for the target ATG terminal determines the target ATG base station based on the measurement results of the downlink signal from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to each other ATG base station, so that when the target ATG terminal needs to switch the ATG base station, it can determine a suitable ATG base station from other ATG base stations based on the signal quality of the downlink signal from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to each other ATG base station.

[0091] When the frequency of communication between the ATG terminal and the ATG base station is the same as the frequency of the IMT base station area, the ATG system (the system in which the ATG terminal communicates with the ATG base station) and the IMT system (the system in which the IMT base station provides communication services) are networked on the same frequency, such as Figure 2 As shown in the figure, when the ATG terminal transmits uplink signals from the aircraft to the ground ATG base station, it will generate co-frequency interference signals to the uplink of the ground IMT base station. In addition, since the coverage area of ​​the ATG terminal when transmitting signals to the ground is very large, a large number of ground IMT base stations will receive the ATG terminal interference signals, which has a huge impact on the performance of the IMT system. At the same time, since the ground IMT base station transmits downlink signals upwards due to the upper side lobes of the antenna, the upper side lobes of each IMT base station antenna are inconsistent, and the transmission link loss to the air is small, the downlink co-frequency signals transmitted to the air by a large number of ground IMT base stations will interfere with the downlink of the ATG base station, and even form a concentrated strong interference area in some airspace where a large number of IMT base station downlink signals are superimposed.

[0092] Moreover, if Figure 3aAs shown, in order to continuously provide aviation mobile ATG services to users on the aircraft during the flight, the ATG terminal switches the uplink and downlink between different ATG base stations and maintains the stability of ATG communication. Therefore, when the ATG base station provides communication services to the ATG terminal, the ATG base station needs to determine under what conditions the target ATG terminal needs to switch the ATG base station. Specifically, it can be determined based on the communication signal quality between the ATG base station and the target ATG terminal and / or whether the uplink signal from the ATG terminal to the ATG base station has uplink interference with the IMT base station in its coverage area and the degree of interference. For example, when the communication signal quality between the ATG base station and the target ATG terminal is lower than a preset threshold, in order to maintain the stability of ATG communication, it can be determined that the ATG terminal needs to switch the ATG base station, or when the uplink signal from the ATG terminal to the ATG base station has uplink interference with the IMT base station in the area covered by the uplink signal, and the degree of interference exceeds the preset threshold, it is determined that the ATG terminal needs to switch the ATG base station.

[0093] When it is determined that the target ATG terminal needs to switch the ATG base station, a measurement instruction for the target ATG terminal is generated and sent to the target ATG terminal. The measurement instruction is used to instruct the target ATG terminal to measure the downlink signals of other ATG base stations. Specifically, the measurement instruction is used to instruct the target ATG terminal to measure the downlink signals of all ATG base stations within its communication range to obtain the measurement results of each downlink signal, wherein the measurement results of each downlink signal represent the quality measurement results of each downlink signal, which may include information representing the signal quality such as the signal-to-noise ratio and / or signal strength of each downlink signal. Then, the quality measurement results of the downlink signals are sent to the ATG base station, and the ATG base station selects the target ATG base station.

[0094] Furthermore, the measurement instruction is used to instruct the target ATG terminal to measure the ATG base stations adjacent to the ATG base station that provides communication services for the target ATG terminal. For example, the ATG terminal currently communicates with ATG base station 1, and ATG base station 1 itself stores the information of the adjacent ATG base stations. If the base stations adjacent to ATG base station 1 are ATG base station 2, ATG base station 3, and ATG base station 4, the ATG terminal can only measure the downlink signals of ATG base station 2, ATG base station 3, and ATG base station 4, and then send the obtained quality measurement results of the downlink signals of the ATG base stations to the ATG base stations, and the ATG base stations select the target ATG base station.

[0095] After the ATG base station receives the measurement results of each downlink signal, it obtains the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to each ATG base station. Among them, the ATG base station can store the specific information of each surrounding IMT base station, and determine the number of IMT base stations in the area covered by the uplink signal of each ATG base station based on the pre-stored location information of each IMT base station. Based on the measurement results of each downlink signal and the number of IMT base stations, the target ATG base station is determined, and a base station switching instruction is sent to the target ATG terminal, and a service instruction for the target ATG terminal is sent to the target ATG base station, so that the target ATG terminal sends an uplink signal to the target ATG base station after receiving the base station instruction. The target ATG base station provides communication services for the target ATG terminal after receiving the service instruction for the target ATG terminal.

[0096] In a possible embodiment, the ATG base station 120 is specifically used for:

[0097] After receiving the measurement results of each of the downlink signals, determining the signal quality of each of the downlink signals;

[0098] When there are no preset number of downlink signals whose signal quality reaches the preset signal quality threshold, the ATG base station 120 with the best signal quality of the corresponding downlink signal is used as the target ATG base station 120;

[0099] When the signal quality of the downlink signals of a preset number of ATG base stations 120 reaches a preset signal quality threshold, for each ATG base station 120 within the communication range, the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal 110 to the ATG base station 120 is obtained; and the ATG base station 120 with the smallest number is used as the target ATG base station 120.

[0100] After the ATG base station receives the measurement results of each downlink signal, it can determine the signal quality of each downlink signal based on any parameter characterizing the signal quality, such as the signal-to-noise ratio and / or the signal strength of the signal. If there are not a preset number of downlink signals whose signal quality reaches the preset signal quality threshold, the ATG base station with the best downlink signal quality is directly selected as the target ATG base station. When there are a preset number of ATG base stations whose downlink signal signal quality reaches the preset signal quality threshold, the ATG base station with a smaller number of IMT network base stations covered by the uplink signal from the ATG terminal to the adjacent ATG base station is preferentially selected as the target ATG base station. The preset number can be set based on actual conditions, for example, set to 1, and is not limited here.

[0101] In order to continuously provide aviation mobile ATG services to users on aircraft during flight, the ATG terminal switches uplink and downlink links between different ATG base stations and maintains the stability of ATG communication. When the ATG terminal switches, if there is only one switching target ATG base station, as long as the signal quality of the target ATG base station meets the requirements, the ATG uplink and downlink links can be switched to the target ATG base station. However, when the ATG terminal switches, if there are multiple target ATG base stations with equivalent signal quality, the ATG base station with fewer IMT network base stations covered by the uplink signal from the ATG terminal to the adjacent ATG base station is preferentially selected as the target ATG base station, thereby reducing the possibility that the uplink signal from the ATG terminal to the ATG base station will interfere with the network corresponding to the IMT base station when the frequency of communication between the ATG base station and the ATG terminal is the same as the network frequency corresponding to the IMT base station.

[0102] In a possible embodiment, the ATG base station 120 is specifically used for:

[0103] When providing communication services for the target ATG terminal 110, if a preset signal sent by a designated IMT base station is received, a measurement instruction is generated; wherein the designated IMT base station is an IMT base station in the area covered by the uplink signal from the target ATG terminal 110 to the ATG base station 120; the preset signal indicates that the uplink signal from the ATG terminal 110 to the ATG base station 120 has uplink interference with the designated IMT base station, and the interference exceeds a preset interference threshold.

[0104] When the IMT base station detects that it is subject to uplink interference, and the uplink interference exceeds the preset interference threshold, the IMT base station sends a preset signal to all the surrounding adjacent ATG base stations 120 to inform all the surrounding adjacent ATG base stations 120 that it is subject to uplink interference. The preset signal may be any indication signal indicating that the uplink signal from the ATG terminal 110 to the ATG base station 120 has uplink interference to it, for example, it may be the interference signal itself, or an indication signal agreed upon between the ATG base station 120 and the IMT, such as signal "1", indicating that the uplink interference is subject to uplink interference and the uplink interference exceeds the preset interference threshold.

[0105] Furthermore, when providing communication services to the target ATG terminal 110, the ATG base station 120 can negotiate with the IMT base station in the area covered by the uplink signal from the target ATG terminal 110 to the ATG base station 120 as to what kind of signal indicates uplink interference to the IMT base station. For example, when the IMT base station sends a signal "1" to the ATG base station 120, it indicates that the uplink signal from the target ATG terminal 110 to the ATG base station 120 causes uplink interference to it, and the uplink interference exceeds a preset interference threshold.

[0106] After each ATG base station 120 receives the preset signal sent by the IMT base station, it can analyze whether the uplink signal of the ATG terminal 110 it serves causes interference to the IMT base station based on the location information of the IMT base station and the location of the ATG terminal 110 it serves. The way in which the ATG base station 120 determines the location information of the IMT base station is as follows: each ATG base station 120 can store attribute information of its neighboring base stations, and the attribute information includes identification information of the IMT base station and the location information of the IMT base station. The preset signal sent by the IMT base station to each ATG base station 120 includes its own identification information. After receiving the preset signal, the ATG base station 120 can determine its corresponding location information based on the identification information of the IMT base station. Then, based on the location information of the ATG terminal 110 that it serves, it determines the coverage area of ​​the uplink signal from the ATG terminal 110 that it serves to the ATG base station 120, and then determines whether the location of the IMT base station is within the coverage area of ​​the uplink signal from the ATG terminal 110 that it serves to the ATG base station 120. If so, it determines that it is the uplink signal of the ATG terminal 110 that it serves that causes interference to the IMT base station.

[0107] If the ATG base station 120 determines that it is the uplink signal of the ATG terminal 110 that it serves that causes interference to the IMT base station, a measurement instruction is generated so that after receiving the above measurement instruction, the target ATG terminal 110 obtains the downlink signals of multiple ATG base stations 120 within the communication range based on the above measurement instruction. The ATG base station 120 currently providing communication services for the target ATG terminal 110 determines the target ATG base station 120 based on the signal quality of the downlink signal from other base stations to the target ATG terminal 110 and the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal 110 to each other ATG base station 120. Therefore, when the target ATG terminal 110 needs to switch the ATG base station 120, a suitable ATG base station 120 can be determined from the other ATG base stations 120 based on the signal quality of the downlink signal from other base stations to the target ATG terminal 110 and the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal 110 to each other ATG base station 120, so as to avoid uplink interference to the network area corresponding to the IMT base station on the ground.

[0108] Exemplarily, the antenna of the ATG terminal 110 is deployed in a multi-faceted array.

[0109] In order to realize the communication between the ATG terminal 110 and the ATG base stations 120 at different locations on the ground, the aircraft needs to switch the uplink and downlink between different ATG base stations 120 when flying on the route. The ATG terminal antenna can adopt the design of omnidirectional antenna or multi-faceted array antenna, because the omnidirectional antenna will receive interference from the ground IMT base station in all directions at the same time, and will interfere with the ground IMT network in a larger range. Therefore, the ATG terminal 110 can adopt the deployment scheme of multi-faceted array antenna, so that after the ATG base station 120 is determined, one antenna can be used to communicate with the ATG base station 120, so that it is not necessary to receive signals from the ground IMT base stations in all directions, and it will not cause interference to the ground IMT base stations in all directions, so as to reduce the possibility that the uplink signal from the ATG terminal 110 to the ATG base station 120 interferes with the network corresponding to the IMT base station when the frequency of the communication between the ATG base station 120 and the ATG terminal 110 is the same as the network frequency corresponding to the IMT base station.

[0110] In a possible embodiment, the ATG terminal 110 includes multiple ATG terminal antennas, and the ATG base station 120 is specifically used for:

[0111] The above-mentioned ATG base station 120 is used to obtain the width of the transmission beam of the ATG terminal antenna corresponding to each ATG base station 120 within the communication range when providing communication services for the target ATG terminal 110;

[0112] Calculate the coverage area of ​​the uplink signal from the target ATG terminal 110 to the ATG base station 120 according to the width of the transmission beam of the ATG terminal antenna;

[0113] Calculate the number of IMT base stations in the above coverage area.

[0114] The ATG terminal includes multiple ATG terminal antennas, and the ATG terminal antennas can be arranged in a multi-faceted array to receive and transmit signals from all angles on the ground. For example, the ATG terminal uses a five-faceted array antenna, with one antenna each for the front, back, left, and right sides, and another antenna facing the ground. After determining the ATG base station that provides communication for it, the ATG terminal can use one antenna to communicate with the ATG base station, such as Figure 3bAs shown, the ATG uplink signal sent by the ATG terminal antenna 2 communicates with the ATG base station 2, and the ATG uplink signal sent by the ATG terminal antenna 3 communicates with the ATG base station 3. At the same time, the uplink signal of the ATG terminal antenna 2 may interfere with the IMT base station in the IMT network area 2, and the uplink signal of the ATG terminal antenna 3 may also interfere with the IMT base station in the IMT network area 3. Therefore, when the ATG base station provides communication services for the target ATG terminal, it can obtain the width of the transmit beam of the ATG terminal antenna corresponding to the ATG base station. Specifically, the ATG terminal can send the width of the transmit beam of the ATG terminal antenna that transmits the radio frequency signal for the ATG base station to the ATG base station, and the ATG base station can calculate the coverage area of ​​the uplink signal from the target ATG terminal to the ATG base station based on the width of the transmit beam of the ATG terminal antenna.

[0115] In addition, the ATG base station can store specific information of each surrounding IMT base station, such as the location information of the IMT base station, etc. After calculating the coverage area of ​​the uplink signal from the target ATG terminal to the ATG base station, it can be determined which IMT base stations are deployed in the area, and further the number of IMT base stations in the area can be determined. In order to reduce the possibility that the uplink signal from the ATG terminal to the ATG base station interferes with the network corresponding to the IMT base station when the frequency at which the ATG base station communicates with the ATG terminal is the same as the network frequency corresponding to the IMT base station.

[0116] like Figure 4 As shown, Figure 4 An interactive schematic diagram of an aviation mobile communication system provided in an embodiment of the present disclosure.

[0117] The ATG base station shown in the figure is an ATG base station that provides communication services for ATG terminals, the neighboring base stations are the neighboring ATG base stations of the ATG base station, the IMT base station is an IMT base station in the uplink signal coverage area from the ATG terminal to the ATG base station, and the signal frequency of the ATG terminal is at least partially the same as the signal frequency of the IMT base station.

[0118] The specific interaction process is as follows:

[0119] S401, when an IMT base station in the uplink signal coverage area of ​​the ATG terminal to the ATG base station detects that the uplink signal from the ATG terminal to the ATG base station generates uplink interference to it, and the interference level exceeds a preset interference signal threshold, a preset signal is generated.

[0120] S402, the IMT base station sends a preset signal to the ATG base station;

[0121] S403, the ATG base station generates a measurement instruction based on the preset signal;

[0122] S404: After the ATG base station generates a measurement instruction, it sends the measurement instruction to the ATG terminal.

[0123] S405, after receiving the measurement instruction, acquiring downlink signals of multiple ATG base stations within the communication range based on the measurement instruction; and obtaining measurement results of each downlink signal;

[0124] S406, sending the measurement result of the downlink signal to the ATG base station that provides communication services to itself;

[0125] S407, ATG base station, is also used to receive the measurement results of each downlink signal, and obtain the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to each ATG base station; determine the target ATG base station based on the measurement results of each downlink signal and the number of IMT base stations; specifically, when the signal quality of the downlink signals of multiple ATG base stations reaches a preset signal quality threshold, for each ATG base station within the communication range, obtain the number of IMT base stations in the area covered by the uplink signal from the ATG terminal to the ATG base station; and use the ATG base station with the smallest number as the target ATG base station;

[0126] S408, the ATG base station sends a base station switching instruction to the target ATG terminal;

[0127] S409, the ATG base station sends a service providing instruction to the target ATG base station;

[0128] S410, the target ATG terminal is used to send an uplink signal to the target ATG base station after receiving a base station instruction; the target ATG base station is used to provide communication services to the target ATG terminal after receiving a service instruction for the target ATG terminal.

[0129] The signal frequency of the ATG terminal is at least partially the same as the signal frequency of the IMT base station, that is, the ATG terminal in aeronautical mobile communications and the ground IMT base station can use the same frequency, so as to broaden the frequency bandwidth that the ATG terminal can use, thereby meeting the user's demand for aeronautical mobile service bandwidth. Moreover, when the target ATG terminal needs to switch the ATG base station, the ATG base station currently providing communication services to the target ATG terminal determines the target ATG base station based on the signal quality of the downlink signal from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to each other ATG base station, so that when the target ATG terminal needs to switch the ATG base station, it can determine a suitable ATG base station from other ATG base stations based on the signal quality of the downlink signal from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to each other ATG base station.

[0130] And when the ATG terminal switches, if there are multiple target ATG base stations with comparable signal quality, the ATG base station with fewer IMT network base stations covered by the uplink signal from the ATG terminal to the adjacent ATG base station is preferentially selected as the target ATG base station, thereby reducing the possibility that the uplink signal from the ATG terminal to the ATG base station will interfere with the network corresponding to the IMT base station when the frequency at which the ATG base station communicates with the ATG terminal is the same as the network frequency corresponding to the IMT base station.
