Embodiments for Carrying Out the Invention

[0023] Hereinafter, with reference to the drawings in the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art based on the present disclosure shall fall within the protection scope of the present disclosure.

[0024] Currently, most of the currently allocated individual ATG dedicated frequencies are only allocated a small bandwidth. Moreover, currently, it is difficult to separately partition some wideband frequencies and use them alone for the ATG system. Since the user needs for the bandwidth of the aeronautical mobile service are constantly improving, it has become an urgent task to provide a solution to meet the user needs for the bandwidth of the aeronautical mobile service.

[0025] The embodiments of the present disclosure disclose an aeronautical mobile communication system, method, device, electronic device and medium, which will be described below respectively.

[0026] The embodiments of the present disclosure provide an aeronautical mobile communication system. Referring to FIG. 1, FIG. 1 is a schematic diagram of the aeronautical mobile communication system according to the embodiments 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] When the target ATG terminal of the communication service provided by the ATG base station itself needs to switch the ATG base station, 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. The ATG terminal 110 may include the target ATG terminal.

[0029] After receiving the measurement command, the target ATG terminal is configured to acquire the downlink signals of a plurality of ATG base stations within the communication range based on the measurement command, obtain the measurement results of each downlink signal, and send the measurement results of each downlink signal to the ATG base station that provides communication services to itself.

[0030] The ATG base station further receives the measurement results of each downlink signal, 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, determines the target ATG base station based on the measurement results of each downlink signal and the number of IMT base stations, sends a base station handover command to the target ATG terminal, and is configured to send a command to provide a service to the target ATG terminal to the target ATG base station.

[0031] After receiving the base station handover command, the target ATG terminal is configured to send an uplink signal to the target ATG base station.

[0032] After receiving the command to provide a service to the target ATG terminal, the target ATG base station is configured to provide a communication 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 the aeronautical mobile communication and the terrestrial IMT base station can adopt the same frequency, so that the bandwidth of the frequency band available for the ATG terminal can be increased, thereby meeting the user's needs for the bandwidth of the aeronautical mobile service. Also, when the target ATG terminal needs to switch the ATG base station, currently, the ATG base station that provides the communication service to 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. Therefore, when the target ATG terminal needs to switch the ATG base station, an appropriate ATG base station can be determined 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.

[0034] When the frequency at which the ATG terminal communicates with the ATG base station is the same as the frequency in the IMT base station area, that is, when the ATG system (the system in which the ATG terminal communicates with the ATG base station) networks with the IMT system (the system in which the IMT base station provides communication services) at the same frequency, as shown in Fig. 2, when the ATG terminal transmits an uplink signal from an airplane to a ground ATG base station, it generates a co-frequency interference signal for the uplink signal of the ground IMT base station. Moreover, since the regional scope covered when the ATG terminal transmits a signal on the ground is very wide, each of a large number of ground IMT base stations receives the interference signal of the ATG terminal, which greatly affects the performance of the IMT system. At the same time, the ground IMT base station transmits a downlink signal with the side lobe on the antenna upward, and the side lobes on the antennas of each IMT base station do not coincide with each other. Moreover, the loss of the air-to-ground transmission link is relatively small. As a result, the downlink co-frequency signals of the air-to-ground transmissions by a large number of ground IMT base stations interfere with the downlink of the ATG base station, and ultimately form a concentrated and strong interference area where the downlink signals of a large number of IMT base stations are superimposed in a part of the space area.

[0035] Furthermore, as shown in Figure 3a, in order to realize continuously providing in-flight ATG services to users on an aircraft during flight, the ATG terminal switches the uplink and downlink 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 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 there is uplink interference from the uplink signal of the ATG terminal to the IMT base station in the area covered by the uplink signal, 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 predetermined threshold, in order to maintain the stability of ATG communication, it may be determined that the ATG terminal needs to switch the ATG base station, or when there is uplink interference from the uplink signal of the ATG terminal to the IMT base station in the area covered by the uplink signal, and the degree of interference exceeds a predetermined threshold, it may be determined that the ATG terminal needs to switch the ATG base station.

[0036] When it is determined that the target ATG terminal needs to switch the ATG base station, a measurement command for the target ATG terminal is generated and the measurement command is sent to the target ATG terminal. The measurement command 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 to obtain the measurement results of each downlink signal. Here, the measurement result of each downlink signal represents the quality measurement result of each downlink signal. Here, the information representing the signal quality such as the signal-to-noise ratio (SNR) and / or signal strength of each downlink signal may be included, and the quality measurement result of the downlink signal is 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 an ATG base station adjacent to the ATG base station that provides a communication service to the target ATG terminal. For example, the target ATG terminal communicates with ATG base station 1, and ATG base station 1 itself stores information on 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 measures only the downlink signals of ATG base station 2, ATG base station 3, and ATG base station 4, and transmits the quality measurement results of the obtained downlink signals of the ATG base stations to the ATG base station, and 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 signals from the target ATG terminal to each ATG base station. Here, the ATG base station stores specific information on each surrounding IMT base station, and based on the pre-stored location information of each IMT base station, can determine the number of IMT base stations in the area covered by the uplink signals of each ATG 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, a base station switching command is transmitted to the target ATG terminal, and a command to provide a service to the target ATG terminal is transmitted to the target ATG base station. After the target ATG terminal receives the base station switching command, it transmits an uplink signal to the target ATG base station, and after the target ATG base station receives the command to provide a service to the target ATG terminal, it provides a communication service to the target ATG terminal.

[0039] In a possible embodiment, the ATG base station After receiving the measurement results of each downlink signal, determines the signal quality of each downlink signal, If there is no predetermined number of ATG base stations whose downlink signal quality reaches a predetermined signal quality threshold, the ATG base station with the best downlink signal quality among the corresponding downlink signals is set as the target ATG base station, When there are a predetermined number of ATG base stations whose downlink signal quality reaches a predetermined 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 target ATG terminal to the ATG base station, and it may be configured to set the ATG base station with the smallest number as 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 a parameter representing any signal quality such as the signal-to-noise ratio of the signal and / or the signal strength of the signal. When there are no predetermined number of ATG base stations whose downlink signal quality reaches the predetermined signal quality threshold, directly select the ATG base station with the best downlink signal quality as the target ATG base station. When there are a predetermined number of ATG base stations whose downlink signal quality reaches the predetermined signal quality threshold, preferentially select 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 as the target ATG base station. The predetermined number can be set based on the actual situation, for example, it can be set to 1, and it is not limited here.

[0041] As shown in FIG. 3, in order to realize continuously providing in-flight mobile ATG services to users on the aircraft during the flight process, the ATG terminal switches the uplink and downlink between different ATG base stations to maintain the stability of ATG communication. When the ATG terminal performs the switching and there is only one target ATG base station to be switched to, as long as the signal quality of the target ATG base station meets the requirements, the ATG uplink and downlink can be switched to the target ATG base station. However, when the ATG terminal performs the switching and there are multiple target ATG base stations with equivalent signal quality, by preferentially selecting 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 as the target ATG base station, when 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 that the uplink signal from the ATG terminal to the ATG base station interferes with the network corresponding to the IMT base station is reduced.

[0042] In a possible embodiment, the ATG base station When providing a communication service to a target ATG terminal, when a predetermined signal transmitted from a designated IMT base station is received, a measurement command may be configured to be generated, 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 the 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 adjacent ATG base stations in the vicinity to notify all adjacent ATG base stations in the vicinity that it has received uplink interference. Here, the predetermined signal may be any indication signal indicating that the uplink signal from the ATG terminal to the ATG base station causes uplink interference to the IMT base station. For example, it may be the interference signal itself or an indication signal agreed upon between the ATG base station and the IMT. For example, the signal "1" indicates that uplink interference has been received and the received uplink interference exceeds a predetermined interference threshold.

[0044] Furthermore, when providing a communication service to a target ATG terminal, the ATG base station can negotiate with the IMT base station in the area covered by the uplink signal from the target ATG terminal to the ATG base station regarding what signal causes uplink interference to the IMT base station. For example, when the IMT base station transmits the signal "1" to the ATG base station, it indicates that the uplink signal from the target ATG terminal to the ATG base station causes uplink interference to that IMT base station and the received uplink interference exceeds a predetermined interference threshold.

[0045] After receiving a predetermined signal transmitted from the IMT base station, each ATG base station can analyze whether the uplink signal of the ATG terminal 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 it serves. The method for the ATG base station to determine the location information of the IMT base station is that each ATG base station can store the attribute information of its adjacent base stations internally. The attribute information includes the identification information of the IMT base station and the location information of the IMT base station. 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. Next, 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 causes interference to the IMT base station.

[0046] When the ATG base station determines that the uplink signal of the ATG terminal it serves is interference generated for the IMT base station, it generates a measurement command. After the target ATG terminal receives the measurement command, it acquires the downlink signals of a plurality of ATG base stations within the communication range based on the measurement command. Currently, when the ATG base station that provides communication services 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, if the target ATG terminal needs to switch the ATG base station, it can determine an appropriate ATG base station from 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, so as to avoid causing uplink interference to the network area corresponding to the terrestrial IMT base station.

[0047] Exemplarily, the antennas of the ATG terminal are arranged in a multi - panel array form.

[0048] In order to realize communication between the ATG terminal and ATG base stations at different positions on the ground, it is necessary to switch the uplink and downlink between different ATG base stations when the airplane is flying on the route. The ATG terminal antenna can adopt a design of an omnidirectional antenna or a multi - panel array antenna. The omnidirectional antenna receives interference from terrestrial IMT base stations in all directions at the same time and interferes with a wider range of terrestrial IMT networks. Therefore, the ATG terminal can adopt the arrangement of the multi - panel array antenna. In this way, after determining the ATG base station, it can communicate with the ATG base station using one - panel antenna. As a result, it is not necessary to receive signals transmitted from terrestrial IMT base stations in all directions, and at the same time, it does not interfere with terrestrial IMT base stations in all directions. Therefore, when 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 that the uplink signal from the ATG terminal to the ATG base station interferes with the network corresponding to the IMT base station can be reduced.

[0049] In a possible embodiment, the ATG terminal may include a plurality of ATG terminal antennas, and the ATG base station may further When providing a communication service to a target ATG terminal, for each ATG base station within each communication range, obtain the width of the transmission beam of the ATG terminal antenna corresponding to the ATG base station, Based on the width of the transmission beam of the ATG terminal antenna, calculate the area covered by the uplink signal from the target ATG terminal to the ATG base station, It may be configured to calculate the number of IMT base stations in the covered area.

[0050] The ATG terminal may include a plurality of ATG terminal antennas, and the ATG terminal antennas may be arranged in a multi-faceted array form, thereby realizing the reception and transmission of signals at each angle on the ground. For example, the ATG terminal adopts one five-sided array antenna, with one antenna on each of the front, back, left, and right, and further has one antenna facing the ground. After determining the ATG base station that provides communication to the ATG terminal, the ATG terminal communicates with the ATG base station using one 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 ATG terminal antenna 2 uplink signal may interfere with the IMT base stations in the IMT network area 2, and the ATG terminal antenna 3 uplink signal may also interfere with the IMT base stations in the IMT network area 3. Therefore, when the ATG base station provides a communication service to the 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 a radio frequency signal to the ATG base station to the ATG base station, and 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 of each surrounding IMT base station, such as the location information of the IMT base station, etc. After calculating the area covered by the uplink signal from the target ATG terminal to the ATG base station, it can determine which IMT base stations are arranged within the area, and further determine the number of IMT base stations in the area. 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, 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 is reduced.

[0052] As shown in FIG. 4, FIG. 4 is a schematic diagram of a dialogue 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 the ATG terminal. The adjacent base station is an adjacent ATG base station of the ATG base station. The IMT base station is an IMT base station in the area covered by the uplink signal from the ATG terminal to the ATG base station. 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, when an IMT base station in the area covered by the uplink signal from the (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 the degree of interference exceeds a predetermined interference signal threshold, a predetermined signal is generated.

[0056] In S402, the IMT base station transmits the 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, after generating a measurement command, the ATG base station transmits the measurement command to the target ATG terminal.

[0059] In S405, after receiving the measurement command, based on the measurement command, it acquires the downlink signals of multiple ATG base stations within the communication range and obtains the measurement results of each downlink signal.

[0060] In S406, it transmits the measurement results of the downlink signals to the ATG base station that provides communication services to itself.

[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 signals 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, when there are multiple ATG base stations whose downlink signal quality reaches a predetermined signal quality threshold, for each ATG base station within the communication range, it obtains the number of IMT base stations in the area covered by the uplink signal from the ATG terminal to the ATG base station, and sets the ATG base station with the smallest number as the target ATG base station.

[0062] In S408, the ATG base station transmits a base station handover command to the target ATG terminal.

[0063] In S409, the ATG base station transmits a command to provide services to the target ATG terminal to the target ATG base station.

[0064] In S410, after receiving the base station command, the target ATG terminal is configured to transmit an uplink signal to the target ATG base station. After receiving the command to provide services to the target ATG terminal, the target ATG base station is configured to provide communication 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, in aeronautical mobile communication, the ATG terminal and the terrestrial IMT base station can adopt the same frequency, so that the available frequency bandwidth of the ATG terminal can be expanded, and the user needs for the bandwidth of aeronautical mobile services can be met. Also, when the target ATG terminal needs to switch to an ATG base station, currently, the ATG base station that provides 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. When the target ATG terminal needs to switch to an ATG base station, an appropriate ATG base station can be determined 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.

[0066] Also, when the ATG terminal performs a switch, if there are multiple target ATG base stations with equivalent signal quality, by preferentially selecting as the target ATG base station 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, when 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 that the uplink signal from the ATG terminal to the ATG base station interferes with the network corresponding to the IMT base station is reduced.

[0067] As shown in FIG. 5, FIG. 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.

[0069] In S520, the measurement results of each downlink signal transmitted from the target ATG terminal of the communication service by itself are received, and the number of IMT base stations in the area covered by the uplink signals from the target ATG terminal to each ATG base station is acquired.

[0070] In S530, the 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 transmitted to the target ATG terminal, and a command to provide a service to the target ATG terminal is transmitted to the target ATG base station. After the target ATG terminal receives the base station command, it transmits an uplink signal to the target ATG base station. After the target ATG base station receives the command to provide a service to the target ATG terminal, it provides a 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, a communication service is provided to the target ATG terminal.

[0073] In a possible embodiment, after receiving the measurement results of each downlink signal transmitted from the target ATG terminal of the communication service by itself, the method includes the step of determining the signal quality of each downlink signal, and the step of determining the target ATG base station based on the signal quality of each downlink signal and the number of IMT base stations If there is no predetermined number of ATG base stations whose downlink signal quality reaches a predetermined signal quality threshold, taking the ATG base station with the best signal quality among the corresponding downlink signals as the target ATG base station; If there is a predetermined number of ATG base stations whose downlink signal quality reaches a predetermined signal quality threshold, for each ATG base station within the communication range, obtaining the number of IMT base stations in the area covered by the uplink signal from the target ATG terminal to the ATG base station, and taking the ATG base station with the smallest number as the target ATG base station.
