[0023] Hereinafter, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only some embodiments of the present disclosure, not all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments in the present disclosure fall within the scope of protection of the present disclosure.
[0024] Currently, most of the individual ATG dedicated frequencies allocated are only allocated with small bandwidths, and it is currently difficult to independently partition some wideband frequencies and use them exclusively for ATG systems. As user needs for bandwidth in the air mobile service continue to increase, it is urgent to provide a solution that meets user needs for bandwidth in the air mobile service.
[0025] Embodiments of the present disclosure disclose an aeronautical mobile communication system, method, device, electronic equipment, and medium, each of which will be described below.
[0026] An embodiment of the present disclosure provides an aeronautical mobile communication system, and reference is made to FIG. 1, which is a schematic diagram of an aeronautical mobile communication system according to an embodiment of the present disclosure.
[0027] The aeronautical mobile communication system includes an ATG terminal 110 and a plurality of ATG base stations 120, and the signal frequency of the ATG terminal is at least partially the same as the signal frequency of the IMT base station.
[0028] The ATG base station is configured to generate a measurement command for the target ATG terminal and send the measurement command to the target ATG terminal when a target ATG terminal of its communication service needs to switch ATG base stations, and the ATG terminal 110 may include the target ATG terminal.
[0029] After receiving the measurement command, the target ATG terminal is configured to acquire downstream signals of multiple ATG base stations within its communication range based on the measurement command, acquire measurement results of each downstream signal, and transmit the measurement results of each downstream signal to the ATG base station that provides communication services to the target ATG terminal.
[0030] The ATG base station is further configured to receive the measurement results of each downlink signal, 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, send a base station switching command to the target ATG terminal, and send a command to the target ATG base station to provide service to the target ATG terminal.
[0031] The target ATG terminal is configured to transmit an uplink signal to the target ATG base station after receiving the base station switching command.
[0032] The target ATG base station is configured to provide communication services to the target ATG terminal after receiving a command to provide service to the target ATG terminal.
[0033] 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 terrestrial IMT base station can adopt the same frequency, thereby expanding the frequency bandwidth available to the ATG terminal and meeting user bandwidth needs for aeronautical mobile services. Furthermore, when the target ATG terminal needs to switch ATG base stations, the ATG base station currently providing communication services to the target ATG terminal determines the target ATG base station based on measurement results of downlink signals from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by uplink signals from the target ATG terminal to each of the other ATG base stations. Therefore, when the target ATG terminal needs to switch ATG base stations, the ATG base station can determine an appropriate ATG base station from the other ATG base stations based on the signal quality of the downlink signals from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by uplink signals from the target ATG terminal to each of the other ATG base stations.
[0034] When the frequency at which the ATG terminal and the ATG base station communicate is the same as the frequency of the IMT base station area, that is, when the ATG system (the system at which the ATG terminal and the ATG base station communicate) performs networking at the same frequency as the IMT system (the system at which the IMT base station provides communication services), as shown in Figure 2, when the ATG terminal transmits an uplink signal from an airplane to a terrestrial ATG base station, it generates an interference signal of the same frequency to the uplink signal of the terrestrial IMT base station.In addition, because the area covered by the ATG terminal when transmitting a signal to the ground is very wide, each of the large number of terrestrial IMT base stations receives the interference signal from the ATG terminal, which has a significant impact on the performance of the IMT system. At the same time, the terrestrial IMT base stations transmit downlink signals with side lobes on the antennas pointing upward, and the side lobes on the antennas of each IMT base station do not coincide with each other. In addition, the loss of the air-to-air transmission link is relatively small. As a result, the downlink same-frequency signals transmitted to the air by a large number of terrestrial IMT base stations interfere with the downlink of the ATG base station, and ultimately form a concentrated, strong interference area in a certain spatial region where the downlink signals of a large number of IMT base stations are superimposed.
[0035] Furthermore, as shown in Figure 3a, in order to continuously provide aeronautical mobile ATG services to users on an aircraft during the flight process, the ATG terminal switches uplink and downlinks between different ATG base stations to maintain the stability of ATG communication. Therefore, when an ATG base station provides communication services to an ATG terminal, the ATG base station needs to determine under what conditions the target ATG terminal needs to switch ATG base stations. Specifically, the determination can be based on the communication signal quality between the ATG base station and the target ATG terminal, and / or whether uplink interference exists between an uplink signal from the ATG terminal to the ATG base station and an IMT base station in the area covered by the uplink signal, and the degree of interference. For example, if the communication signal quality between the ATG base station and the target ATG terminal is lower than a predetermined threshold, the ATG terminal may determine that it needs to switch ATG base stations to maintain the stability of ATG communication. Alternatively, if uplink interference exists between an uplink signal from the ATG terminal to the ATG base station and an IMT base station in the area covered by the uplink signal, and the degree of interference exceeds a predetermined threshold, the ATG terminal may determine that it needs to switch ATG base stations.
[0036] When the target ATG terminal determines that it needs to switch ATG base stations, it generates a measurement command for the target ATG terminal and sends the measurement command to the target ATG terminal, which is used to instruct the target ATG terminal to measure the downlink signals of other ATG base stations. Specifically, the measurement command is used to instruct the target ATG terminal to measure the downlink signals of all ATG base stations within its communication range and obtain measurement results for each downlink signal. Here, the measurement results for each downlink signal represent quality measurement results for each downlink signal, which may include information representing signal quality such as the signal-to-noise ratio (SNR) and / or signal strength of each downlink signal. The quality measurement results for the downlink signals are then sent to the ATG base station, and the target ATG base station is selected by the ATG base station.
[0037] Furthermore, the measurement command is used to instruct the target ATG terminal to measure ATG base stations adjacent to the ATG base station that provides communication services to the target ATG terminal. For example, if the target ATG terminal communicates with ATG base station 1, and ATG base station 1 itself stores information about the adjacent ATG base stations, and 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 measures only the downlink signals of ATG base station 2, ATG base station 3, and ATG base station 4, and transmits the acquired measurement results of the quality of the downlink signals of the ATG base stations to the ATG base station, so that the ATG base station can select the target ATG base station.
[0038] After receiving the measurement results of each downlink signal, the ATG base station 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. Here, the ATG base station stores specific information about each surrounding IMT base station and can 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. The target ATG base station is determined based on the measurement results of each downlink signal and the number of IMT base stations, and sends a base station switching command to the target ATG terminal, which then sends a command to provide service to the target ATG terminal. After the target ATG terminal receives the base station switching command, it sends an uplink signal to the target ATG base station. After receiving the command to provide service to the target ATG terminal, the target ATG base station provides communication service to the target ATG terminal.
[0039] In a possible embodiment, the ATG base station: After receiving the measurement results for each downstream signal, determining the signal quality of each downstream signal; If there is no predetermined number of ATG base stations whose signal quality of the downlink signal reaches the predetermined signal quality threshold, the ATG base station whose corresponding downlink signal has the best signal quality is set as the target ATG base station; When there is a predetermined number of ATG base stations whose signal quality of the downlink signal reaches a predetermined signal quality threshold, the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to the ATG base station is obtained for each ATG base station within its communication range, and the ATG base station with the smallest number may be configured to be the target ATG base station.
[0040] After receiving the measurement results of each downlink signal, the ATG base station determines the signal quality of each downlink signal based on parameters representing any signal quality, such as the signal-to-noise ratio of the signal and / or the signal strength of the signal. If there are not a predetermined number of ATG base stations whose signal quality of the downlink signal reaches a predetermined signal quality threshold, it directly selects the ATG base station whose downlink signal quality is the best as the target ATG base station. If there are a predetermined number of ATG base stations whose signal quality of the downlink signal reaches a predetermined signal quality threshold, it preferentially selects the ATG base station whose number of IMT network base stations covered by the uplink signal from the ATG terminal to the adjacent ATG base station as the target ATG base station. The predetermined number can be set based on the actual situation, for example, can be set to 1, and is not limited here.
[0041] As shown in Figure 3, in order to continuously provide aeronautical mobile ATG services to users on the aircraft during the flight process, the ATG terminal switches uplink and downlinks between different ATG base stations to maintain the stability of ATG communication. When the ATG terminal switches, if there is only one target ATG base station to be switched to, it can switch the ATG uplink and downlink to the target ATG base station as long as the signal quality of the target ATG base station meets the requirements. However, when the ATG terminal switches, if there are multiple target ATG base stations with equivalent signal quality, it will preferentially select the ATG base station with the fewest IMT network base stations covered by the uplink signal from the ATG terminal to the adjacent ATG base station as the target ATG base station. By doing so, if the frequency on which the ATG base station and the ATG terminal communicate is the same as the network frequency corresponding to the IMT base station, the possibility of the uplink signal from the ATG terminal to the ATG base station interfering with the network corresponding to the IMT base station is reduced.
[0042] In a possible embodiment, the ATG base station: When providing communication services to a target ATG terminal, a measurement command may be generated when a predetermined signal transmitted from a designated IMT base station is received, where the designated IMT base station is an IMT base station in an area covered by an uplink signal from the target ATG terminal to the ATG base station, and the predetermined signal indicates that the uplink signal from the target ATG terminal to the ATG base station causes uplink interference to the designated IMT base station and the interference exceeds a predetermined interference threshold.
[0043] When an IMT base station detects that it has received uplink interference and the received uplink interference exceeds a predetermined interference threshold, the IMT base station transmits a predetermined signal to all of its neighboring ATG base stations to notify them that it has received uplink interference. Here, the predetermined signal may be any indication signal indicating that an uplink signal from an ATG terminal to the ATG base station causes uplink interference to the IMT base station, for example, the interference signal itself or an indication signal agreed upon between the ATG base station and the IMT, for example, a signal "1" indicates that it has received uplink interference and that the received uplink interference exceeds a predetermined interference threshold.
[0044] Furthermore, when providing communication services to a target ATG terminal, the ATG base station can negotiate with an IMT base station in the area covered by the uplink signal from the target ATG terminal to the ATG base station to indicate what signal has caused uplink interference to the IMT base station. For example, if an IMT base station transmits a signal "1" to an ATG base station, this indicates that the uplink signal from the target ATG terminal to the ATG base station has caused uplink interference to the IMT base station and that the received uplink interference exceeds a predetermined interference threshold.
[0045] After receiving a predetermined signal transmitted from an IMT base station, each ATG base station can analyze whether the uplink signal of the ATG terminal it serves is causing interference to the IMT base station based on the location information of the IMT base station and the location of the ATG terminal it serves. The ATG base station determines the location information of the IMT base station by storing attribute information of its neighboring base stations within each ATG base station, the attribute information including identification information of the IMT base station and location information of the IMT base station, and the predetermined signal transmitted from the IMT base station to each ATG base station includes its own identification information. After receiving the predetermined signal, the ATG base station can determine the corresponding location information based on the identification information of the IMT base station. Then, based on the location information of the ATG terminal it serves, it determines the area covered by the uplink signal from the ATG terminal it serves to the ATG base station. Then, it determines whether the location of the IMT base station is within the area covered by the uplink signal from the ATG terminal it serves to the ATG base station. If so, it determines that the uplink signal of the ATG terminal it serves is causing interference to the IMT base station.
[0046] When an ATG base station determines that the uplink signal of the ATG terminal it serves is causing interference to the IMT base station, it generates a measurement command, and after the target ATG terminal receives the measurement command, it acquires downlink signals of multiple ATG base stations within its communication range based on the measurement command. The ATG base station currently providing communication service to the target ATG terminal determines the target ATG base station based on the signal quality of the downlink signals from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by the uplink signals from the target ATG terminal to each other ATG base station. When the target ATG terminal needs to switch ATG base stations, it can determine an appropriate ATG base station from the other ATG base stations based on the signal quality of the downlink signals from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by the uplink signals from the target ATG terminal to each other ATG base station, thereby avoiding causing uplink interference to the network area corresponding to the terrestrial IMT base station.
[0047] Illustratively, the antennas of the ATG terminals are arranged in a multi-plane array format.
[0048] To realize communication between the ATG terminal and ATG base stations at different locations on the ground, the aircraft needs to switch uplink and downlink links between different ATG base stations as it flies along its route. The ATG terminal antenna can adopt an omnidirectional antenna or a multi-plane array antenna design. Because an omnidirectional antenna simultaneously receives interference from terrestrial IMT base stations in all directions and interferes with a wider-area terrestrial IMT network, the ATG terminal can adopt a multi-plane array antenna layout design. In this way, after determining an ATG base station, it can communicate with the ATG base station using a single antenna, thereby eliminating the need to receive signals transmitted from terrestrial IMT base stations in all directions and simultaneously avoiding interference with terrestrial IMT base stations in all directions. Therefore, when the frequency used for communication between the ATG base station and the ATG terminal is the same as the network frequency corresponding to the IMT base station, the possibility of the uplink signal from the ATG terminal to the ATG base station interfering with the network corresponding to the IMT base station is reduced.
[0049] In a possible embodiment, the ATG terminal may include a plurality of ATG terminal antennas, and the ATG base station further comprises: When providing communication services to a target ATG terminal, for each ATG base station within the communication range, obtain the width of the transmission beam of the ATG terminal antenna corresponding to the ATG base station; Calculate the area covered by the uplink signal from the target ATG terminal to the ATG base station based on the width of the transmission beam of the ATG terminal antenna; It may be configured to calculate the number of IMT base stations in the coverage area.
[0050] The ATG terminal may include multiple ATG terminal antennas, and the ATG terminal antennas may be arranged in a multi-plane array format to achieve reception and transmission of signals from various angles on the ground. For example, the ATG terminal may employ a five-plane array antenna, with one antenna on each of the front, rear, left, and right sides, and an additional antenna facing the ground. After determining which ATG base station will provide communication for the ATG terminal, the ATG terminal communicates with the ATG base station using the one-plane antenna. As shown in Figure 3b, the ATG uplink signal transmitted from ATG terminal antenna 2 communicates with ATG base station 2, and the ATG uplink signal transmitted from ATG terminal antenna 3 communicates with ATG base station 3. At the same time, the uplink signal from ATG terminal antenna 2 may interfere with the IMT base station in IMT network area 2, and the uplink signal from ATG terminal antenna 3 may also interfere with the IMT base station in IMT network area 3. Therefore, when an ATG base station provides communication services to a target ATG terminal, it can obtain the width of the transmission beam of the ATG terminal antenna corresponding to the ATG base station. Specifically, the ATG terminal can transmit the width of the transmission beam of the ATG terminal antenna that transmits radio frequency signals to the ATG base station to the ATG base station. The ATG base station can calculate the area covered by the uplink signal from the target ATG terminal to the ATG base station based on the width of the transmission beam of the ATG terminal antenna.
[0051] In addition, the ATG base station can store specific information about each surrounding IMT base station, such as location information of the IMT base station, and after calculating the area covered by the uplink signal from the target ATG terminal to the ATG base station, can determine which IMT base stations are located within the area and further determine the number of IMT base stations in the area.If the frequency used for communication between the ATG base station and the ATG terminal is the same as the network frequency corresponding to the IMT base station, this reduces 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.
[0052] As shown in FIG. 4, FIG. 4 is a schematic diagram of an interaction applied to an aeronautical mobile communication system according to an embodiment of the present disclosure.
[0053] The ATG base station shown in the figure is an ATG base station that provides communication services to an ATG terminal, the adjacent base station is an ATG base station adjacent to the ATG base station, the IMT base station is an IMT base station in an area covered by an uplink signal 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.
[0054] The specific dialogue process is as follows:
[0055] In S401, an IMT base station in an area covered by an uplink signal from a (target) ATG terminal to the ATG base station detects that the uplink signal from the ATG terminal to the ATG base station causes uplink interference to it, and generates a predetermined signal if the degree of interference exceeds a predetermined interference signal threshold.
[0056] In S402, the IMT base station transmits a predetermined signal to the ATG base station.
[0057] In S403, the ATG base station generates a measurement command based on the predetermined signal.
[0058] In S404, the ATG base station generates a measurement command and then transmits the measurement command to the target ATG terminal.
[0059] In S405, after receiving the measurement command, the downstream signals of the multiple ATG base stations within the communication range are acquired based on the measurement command, and the measurement results of each downstream signal are obtained.
[0060] In S406, the measurement result of the downstream signal is transmitted to the ATG base station that provides communication services to the ATG base station.
[0061] In S407, the ATG base station is further configured to receive the measurement results of each downlink signal, 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, and determine the target ATG base station based on the measurement results of each downlink signal and the number of IMT base stations; specifically, if there are multiple ATG base stations whose signal quality of the downlink signal reaches a predetermined signal quality threshold, for each ATG base station within its communication range, the number of IMT base stations in the area covered by the uplink signal from the ATG terminal to the ATG base station is obtained, and the ATG base station with the smallest number is determined to be the target ATG base station.
[0062] In S408, the ATG base station transmits a base station switching command to the target ATG terminal.
[0063] In S409, the ATG base station sends a command to the target ATG base station to provide service to the target ATG terminal.
[0064] In S410, the target ATG terminal is configured to transmit an uplink signal to the target ATG base station after receiving a base station command, and the target ATG base station is configured to provide communication services to the target ATG terminal after receiving a command to provide services to the target ATG terminal.
[0065] 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 and the terrestrial IMT base station in aeronautical mobile communications can use the same frequency, thereby expanding the frequency bandwidth available to the ATG terminal and meeting user bandwidth needs for aeronautical mobile services. Furthermore, when the target ATG terminal needs to switch ATG base stations, 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 downstream signals from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by upstream signals from the target ATG terminal to each of the other ATG base stations. Therefore, when the target ATG terminal needs to switch ATG base stations, the ATG base station currently providing communication services to the target ATG terminal can determine the appropriate ATG base station from the other ATG base stations based on the signal quality of downstream signals from other base stations to the target ATG terminal and the number of IMT base stations in the area covered by upstream signals from the target ATG terminal to each of the other ATG base stations.
[0066] In addition, when an ATG terminal switches, if there are multiple target ATG base stations with equivalent signal quality, the ATG base station with the fewest 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.By doing so, if the frequency at which the ATG base station and the ATG terminal communicate is the same as the network frequency corresponding to the IMT base station, the possibility of the uplink signal from the ATG terminal to the ATG base station interfering with the network corresponding to the IMT base station is reduced.
[0067] As shown in Figure 5, Figure 5 is a flowchart of an aeronautical mobile communication method of an ATG base station applied to an aeronautical mobile communication system according to an embodiment of the present disclosure, where the system may include an ATG terminal and a plurality of ATG base stations, and the signal frequency of the ATG terminal is at least partially the same as the signal frequency of the IMT base station, and the method may include the following steps:
[0068] In S510, when the target ATG terminal for which it provides communication services needs to switch ATG base stations, it generates a measurement command for the target ATG terminal and sends the measurement command to the target ATG terminal, so that the target ATG terminal acquires downstream signals from multiple ATG base stations within its communication range based on the measurement command, acquires the measurement results of each downstream signal, and sends the measurement results of each downstream signal to the ATG base station that provides communication services to it.
[0069] At S520, the measurement results of each downstream signal transmitted from the target ATG terminal of the communication service provided by the own communication service are received, and the number of IMT base stations in the area covered by the upstream signal from the target ATG terminal to each ATG base station is obtained.
[0070] In S530, a target ATG base station is determined based on the measurement results of each downlink signal and the number of IMT base stations.
[0071] In S540, a base station switching command is sent to the target ATG terminal, and a command to provide service to the target ATG terminal is sent to the target ATG base station, so that after the target ATG terminal receives the base station command, it transmits an uplink signal to the target ATG base station, and after the target ATG base station receives the command to provide service to the target ATG terminal, it provides communication service to the target ATG terminal.
[0072] In S550, when a command to provide a service to the target ATG terminal transmitted from another ATG base station is received, the communication service is provided to the target ATG terminal.

[0077] In S610, a measurement command sent from the ATG base station that provides communication services to the station is obtained, and the measurement command is generated by the ATG base station that provides communication services to the station when the station needs to switch the ATG base station.
[0078] In S620, downlink signals of a plurality of ATG base stations within the communication range are acquired based on the measurement command, and measurement results of each downlink signal are obtained.
