Description

Background Art

[0002] In the field of wireless communication technology, the Air-to-Ground (ATG) wireless broadband communication system uses mature land mobile communication technology to deploy ATG base stations along the flight route to transmit radio signals to the air, and use ground-to-air communication links to provide high-bandwidth communication services to aircraft in the air. The ATG base station deploys antennas to provide air coverage, and the aircraft receives ground signals through the ATG airborne terminal installed on the aircraft, which converts them into WiFi signal coverage in the cabin, effectively realizing high-speed data transmission between the ground and the air. Compared with satellite communications, ATG has the advantages of high data bandwidth, low latency, low cost, and high reliability that is not affected by weather.

[0003] In the related technology, ATG base stations need to be deployed at the same frequency as ground IMT (International Mobile Telecommunications) base stations due to the limited available spectrum resources. When the uplink of the ATG airborne terminal is at the same frequency as the uplink of the public network, the signal transmission of the ATG airborne terminal in the air will interfere with the ground IMT base stations of the same frequency and adjacent frequencies, thereby affecting the use of the public network.

[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0034] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0035] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0036] Figure 1 A schematic diagram of an exemplary ATG system architecture that can be applied to the uplink transmit power control method or uplink transmit power control device of the embodiments of the present disclosure is shown.

[0037] like Figure 1 As shown, the ATG system architecture may include an aircraft 101, an ATG airborne terminal 102, an ATG base station 103, a ground IMT base station 104 and a terminal device 105. The ATG airborne terminal 102 is installed on the aircraft 101. The ATG airborne terminal 102 receives the radio signal transmitted by the ATG base station 103 and converts it into a WiFi signal in the cabin of the aircraft 101, which is supplied to the terminal device 105 in the cabin. When the ATG airborne terminal 102 transmits a radio signal to the ATG base station 103, it will interfere with the ground IMT base station 104.

[0038] The ATG airborne terminal 102 and the ATG base station 103 as well as the ATG airborne terminal 102 and the terminal device 105 are connected via a network, wherein the network may be a wired network or a wireless network.

[0039] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged through the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above data communication technologies.

[0040] The terminal device 105 can be various electronic devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, etc.

[0041] Optionally, the client of the application installed in different terminal devices 105 is the same, or the client of the same type of application based on different operating systems. Based on the different terminal platforms, the specific form of the client of the application can also be different, for example, the application client can be a mobile client, a PC client, etc.

[0042] In the related technology, there is no dedicated frequency for ATG system in China at present. The commercial use of ATG system may consider co-frequency reuse with other communication systems and deploy ATG network with the same frequency as IMT network. When ATG uplink and IMT uplink are co-frequency, since ATG airborne terminal 102 is at an altitude of 3km to 10km from the ground, the geographical area where ATG airborne terminal 102 generates uplink co-frequency interference to ground IMT network is very wide, and the number of ground IMT base stations affected by uplink co-frequency interference of ATG airborne terminal is large, thus affecting the normal use of IMT network. The traditional closed-loop power control method has good effect, but it requires ATG base station to send power control instructions to ATG airborne terminal. In ATG network, since ATG airborne terminal is very far away from ATG base station, transmission link delay is large, and ATG airborne terminal flies fast, the feedback-based power control mechanism in ATG network is not effective.

[0043] In addition, if Figure 2 As shown, the ATG airborne terminal 102 is installed on the aircraft 101. The uplink interference of the ATG airborne terminal 102 to the same-frequency ground IMT network is related to the incident angle of the uplink signal of the ATG airborne terminal 102 and the pointing direction of the side lobe on the antenna of the ground IMT base station 104. When the incident angle of the uplink signal of the ATG airborne terminal 102 coincides with the pointing direction of the side lobe on the antenna of the ground IMT base station 104, the uplink interference of the ATG airborne terminal 102 to the IMT network is the greatest. The pointing directions of the side lobes on the antennas of the ground IMT base stations 104 are different, and the uplink interference they receive from the same-frequency ATG airborne terminal 102 is also different. Even if the ATG airborne terminal 102 is at the same flight altitude, the uplink interference to different ground IMT base stations 104 in the same area is different.

[0044] In an embodiment of the present disclosure, a method for controlling uplink transmission power is provided, which obtains interference parameters of uplink interference of a ground IMT base station 104, wherein the interference parameters of uplink interference of the ground IMT base station 104 are interference parameters of interference caused by the ATG airborne terminal 102 to the ground IMT base station 104; determines the uplink transmission power of the ATG airborne terminal 102 corresponding to the interference parameters; and controls the ATG airborne terminal to operate with the uplink transmission power. The method can be applied to scenarios where the airborne mobile communication ATG network and the IMT network are deployed at the same frequency, such as scenarios where there is uplink co-frequency interference between the ATG network and the IMT network. The present disclosure obtains the interference parameters of the uplink interference of the ground IMT base station 104, determines the uplink transmission power of the ATG airborne terminal 102 corresponding to the interference parameters, thereby reducing the interference caused by the signal transmission of the ATG airborne terminal 102 to the ground IMT base station 104 with the same frequency and adjacent frequency, ensures the normal use of the public network, and controls the uplink transmission power in a timely manner without delay.

[0045] Those skilled in the art will know that Figure 1 The number of aircraft 101, ATG airborne terminal 102, ATG base station 103, ground IMT base station 104 and terminal device 105 is only illustrative, and any number of aircraft 101, ATG airborne terminal 102, ATG base station 103, ground IMT base station 104 and terminal device 105 may be provided according to actual needs. The embodiments of the present disclosure are not limited to this.

[0046] Under the above ATG system architecture, an uplink transmission power control method is provided in the embodiments of the present disclosure, and the method can be executed by any electronic device with computing and processing capabilities. In some embodiments, the uplink transmission power control method provided in the embodiments of the present disclosure can be performed in Figure 1 The process is executed in the ATG airborne terminal 102, ATG base station 103 or terrestrial IMT base station 104 shown.

[0047] Figure 3 An uplink transmission power control method in an embodiment of the present disclosure is shown. Figure 3 As shown, the uplink transmission power control method provided in the embodiment of the present disclosure is applied to the ATG system, the ATG system includes an ATG airborne terminal, the ATG airborne terminal is installed on the aircraft, and the method includes the following S301 to S303.

[0048] S301. Obtain interference parameters of uplink interference of a terrestrial international mobile phone system IMT base station. The interference parameters of uplink interference of a terrestrial IMT base station are interference parameters of interference caused by an ATG airborne terminal to the terrestrial IMT base station.

[0049] Among them, the interference parameters include interference intensity and the number of interfered ground IMT base stations. The interference intensity is used to indicate the strength of the interference caused by the radio signal emitted by the ATG airborne terminal to the ground IMT base station. The interference intensity is the interference intensity corresponding to multiple ground IMT base stations. One ground IMT base station corresponds to one interference intensity. The interference intensity can be represented by one or more forms of text, letters, numbers, symbols, etc., which are not limited in the embodiments of the present disclosure. For example, the interference intensity is represented by a number from 0 to 100. If the interference intensity is 0, the interference of the ATG airborne terminal to the ground IMT base station is the weakest; if the interference intensity is 100, the interference of the ATG airborne terminal to the ground IMT base station is the strongest. The number of interfered ground IMT base stations is the number of ground IMT base stations when the interference intensity is greater than the interference threshold. The interference threshold can be set as needed.

[0050] S302: Determine the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter.

[0051] Among them, the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter is the actual transmission power to ensure the normal use and operation of the public network. According to the interference parameter, the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter is determined, including multiple determination methods, such as obtaining it by querying a correspondence table, and the correspondence table stores the interference parameter and the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter. For another example, the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter is obtained through a formula, a combination of graphics or a model. The specific determination method of determining the uplink transmission power through the interference parameter is not limited in the embodiment of the present disclosure.

[0052] S303. Control the ATG airborne terminal to operate at uplink transmission power.

[0053] After determining the uplink transmission power of the ATG airborne terminal corresponding to the interference intensity, the ATG airborne terminal operates at the uplink transmission power, thereby reducing the interference caused by the ATG airborne terminal signal transmission to the same-frequency and adjacent-frequency ground IMT base stations, and ensuring the normal use of the public network.

[0054] Figure 4 A flow chart of a method for determining interference strength in an embodiment of the present disclosure is shown. Figure 4 As shown, before obtaining interference parameters of uplink interference of a terrestrial international mobile telephone system IMT base station, the method for determining the interference parameters includes the following steps S401 to S404.

[0055] S401. Acquire flight parameters and preset segmentation parameters of the ATG airborne terminal, and determine the flight position of the ATG airborne terminal according to the flight parameters and the preset segmentation parameters.

[0056] In some embodiments, the flight parameters include a flight trajectory of the ATG airborne terminal; the preset segmentation parameters include an interference assessment time interval;

[0057] Acquire the flight parameters and preset segmentation parameters of the ATG airborne terminal, and determine the flight position of the ATG airborne terminal according to the flight parameters and the preset segmentation parameters, including:

[0058] A plurality of flight trajectory segments are obtained according to the interference assessment time interval and the flight trajectory;

[0059] According to the flight trajectory segment, the flight position of the ATG airborne terminal is determined.

[0060] For example, Figure 5As shown, the interference assessment time interval t divides the flight trajectory s into three flight trajectory segments, and determines the specific position of each flight trajectory segment as the flight position of the ATG airborne terminal, wherein the specific position may be the starting position, the middle position or the ending position of the flight trajectory segment, the starting position is such as the position a, the middle position is such as the position b, and the ending position is such as the position c. It should be noted that if the starting position of the flight trajectory segment is determined to be the flight position of the ATG airborne terminal, then the starting position in each flight trajectory segment is the flight position of the ATG airborne terminal in the flight trajectory segment.

[0061] It should be noted that the flight trajectory is composed of flight trajectory points, and each flight trajectory point contains information such as flight position, flight altitude, flight direction and flight speed. The flight position can be the longitude and latitude of the trajectory point, or it can be the coordinate position of the trajectory point in the coordinate system established based on the plane where the flight trajectory is located.

[0062] S402. Determine a target interference area corresponding to the flight position, wherein the target interference area is one of a plurality of interference areas obtained by dividing a flight strip that the ATG airborne terminal passes along a preset flight direction according to preset segmentation parameters.

[0063] In some embodiments, the preset segmentation parameters also include a distance offset;

[0064] Determine a target interference area corresponding to the flight position, wherein the target interference area is one of a plurality of interference areas in which a flight strip passed by the ATG airborne terminal along a preset flight direction is divided according to preset segmentation parameters, including:

[0065] According to the flight trajectory and the distance offset, the flight zone that the ATG airborne terminal passes through along the preset flight direction is determined;

[0066] According to the interference assessment time interval, the flight strip that the ATG airborne terminal passes along the preset flight direction is divided into multiple interference areas.

[0067] Among them, the distance offset is preset on the ATG airborne terminal or the ground IMT base station, and the size of the distance offset can be set as needed. For example, when the ATG airborne terminal is at a higher altitude, the offset is set to a larger value. For example, when the ATG airborne terminal is at a higher altitude of 15 kilometers, the offset is set to 1 kilometer.

[0068] For example, Figure 6 As shown, the distance from the boundary line 603 to the flight trajectory s is the distance offset d, and the area between the two boundary lines 603 parallel to the flight trajectory s is the flight belt that the ATG airborne terminal passes along the preset flight direction. According to the interference evaluation time interval t, the flight belt that the ATG airborne terminal passes along the preset flight direction is divided into three interference areas, namely Figure 6 The area between the two dotted lines.

[0069] It should be noted that the size of the distance offset can be constant or variable, depending on the location and number of ground IMT base stations and the needs of the terrain. The specific value of the distance offset is variable or constant, and the embodiments of the present disclosure do not limit this.

[0070] S403: Determine the ground IMT base station in the target interference area, and obtain antenna parameters of the ground IMT base station in the target interference area.

[0071] The antenna parameters include the antenna azimuth, antenna downtilt and antenna pattern of the ground IMT base station. The interference intensity of the ground IMT base station uplink interference is related to the antenna parameters of the ground IMT base station. The upper sidelobe pointing of the ground IMT base station antenna is determined according to one or more of the antenna azimuth, antenna downtilt and antenna pattern included in the ground IMT base station antenna parameters, in preparation for determining the interference parameters of the ground IMT base station uplink interference.

[0072] S404: Determine interference parameters of uplink interference of the ground IMT base station according to antenna parameters and flight position.

[0073] According to the flight position of the ATG airborne terminal and the antenna parameters of the ground IMT base station, the relationship between the incident angle of the ATG airborne terminal uplink signal and the side lobe pointing of the ground IMT base station antenna is determined, thereby determining the interference intensity of the ground IMT base station uplink interference. For example, if the incident angle of the ATG airborne terminal uplink signal coincides with the side lobe pointing of the ground IMT base station antenna, the interference intensity of the ground IMT base station uplink interference is the largest. The number of interfered ground IMT base stations is determined by the interference intensity and the interference threshold.

[0074] For example, Figure 6 As shown, the interference area that the ATG airborne terminal is expected to fly into is the target interference area. The incident angle of the uplink signal of the ATG airborne terminal is determined according to the positional relationship between the flight position 601 of the ATG airborne terminal in the target interference area and the ground IMT base station 602, thereby determining the relationship between the incident angle of the uplink signal of the ATG airborne terminal and the side lobe pointing direction of the ground IMT base station antenna.

[0075] The present invention not only considers the influence of the flight altitude of the ATG airborne terminal on the interference intensity of the uplink interference of the ground IMT base station, but also considers the influence of the relationship between the incident angle of the uplink signal of the ATG airborne terminal and the sidelobe pointing of the ground IMT base station antenna on the interference intensity of the uplink interference of the ground IMT base station. According to the interference parameters, the uplink transmission power of the ATG airborne terminal is determined to ensure the normal operation of the public network.

[0076] In some embodiments, the interference strength is evaluated by an ATG airborne terminal or a ground IMT base station.

[0077] Exemplarily, when the interference parameters are evaluated by the ATG airborne terminal, the interference parameters are obtained in the following manner: the ATG airborne terminal receives the antenna parameters of the ground IMT base station sent by the ground IMT base station in the target interference area through the ATG base station; the ATG airborne terminal obtains the flight parameters of the ATG airborne terminal; the ATG airborne terminal obtains the interference parameters based on the flight parameters and antenna parameters.

[0078] It should be noted that, when evaluating interference parameters, the ATG airborne terminal may complete the evaluation of the interference parameters in advance before the aircraft takes off, or may complete the evaluation of the interference parameters during or after the aircraft takes off. The disclosed embodiment does not limit this. As long as the interference parameter evaluation of the target interference area is completed before the ATG airborne terminal follows the aircraft into the target interference area, the uplink transmission power is controlled according to the interference parameters, and the interference power is evaluated in advance, and the uplink transmission power is controlled in time, so that the public network can be used normally to meet people's needs.

[0079] Exemplarily, when the interference parameters are evaluated by the ground IMT base station, the interference parameters are obtained in the following manner: the ground IMT base station receives the flight parameters of the ATG airborne terminal sent by the ATG airborne terminal through the ATG base station; the ground IMT base station obtains the antenna parameters of the ground IMT base station in the target interference area; the ground IMT base station obtains the interference parameters based on the flight parameters and antenna parameters; the ground IMT base station sends the interference parameters to the ATG airborne terminal through the ATG base station.

[0080] It should be noted that, when evaluating interference parameters, the ground IMT base station can complete the evaluation of the interference parameters in advance before the aircraft takes off, or can complete the evaluation of the interference parameters when the aircraft takes off or after take-off. The embodiments of the present disclosure do not limit this. The ground IMT base station only needs to complete the interference parameter evaluation of the target interference area before the ATG airborne terminal follows the aircraft to fly into the target interference area, and send the evaluation result to the ATG airborne terminal. It controls the uplink transmission power according to the interference parameters, evaluates the interference power in advance, and controls the uplink transmission power in time, so that the public network can be used normally to meet people's needs.

[0081] In some embodiments, the interference parameters include the interference intensity of the terrestrial IMT base station uplink interference and the number of interfered terrestrial IMT base stations;

[0082] Determine the uplink transmission power of the ATG airborne terminal corresponding to the interference parameters, including: obtaining the interference intensity and the number of interfered ground IMT base stations, the number of interfered ground IMT base stations is the number of ground IMT base stations when the interference intensity is greater than the interference threshold; if the number of interfered ground IMT base stations meets the preset interference condition, determine the uplink transmission power of the ATG airborne terminal corresponding to the number of interfered ground IMT base stations.

[0083] Among them, the interfered ground IMT base station is a ground IMT base station with an interference intensity greater than an interference threshold. The interference threshold can be preset on the ATG airborne terminal for comparison with the interference intensity to determine whether the interference intensity meets the condition. For example, the interference threshold is 1, and the number of interfered ground IMT base stations with an interference intensity greater than 1 for uplink interference of the ground IMT base station is counted. The preset interference condition can be a range of values ​​or a specific value. The specific preset interference condition is not limited in the embodiment of the present disclosure. For example, the preset interference condition is that the number of interfered ground IMT base stations with an interference intensity greater than 1 ranges from 100 to 500, and the corresponding uplink transmission power of the ATG airborne terminal is 20 dBm (decibel milliwatts). If the number of interfered ground IMT base stations with an interference intensity greater than 1 in the target interference area is 200, and 200 is within the range of 100-500, and the preset interference condition is met, then the ATG airborne terminal operates with an uplink transmission power of 20 dBm.

[0084] In some embodiments, the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter is determined, including: obtaining the interference intensity and the number of interfered ground IMT base stations, the number of interfered ground IMT base stations being the number of ground IMT base stations when the interference intensity is greater than the interference threshold; if the number of interfered ground IMT base stations does not meet the preset interference condition, the ATG airborne terminal operates according to the original uplink transmission power.

[0085] Exemplarily, the preset interference condition is that the number of ground IMT base stations with interference intensity greater than 1 is in the range of 100-500, and the corresponding uplink transmission power of the ATG airborne terminal is 20dBm. If the number of interfered ground IMT base stations with interference intensity greater than 1 in the target interference area is 80, and 80 is not in the range of 100-500, and the preset interference condition is not met, the ATG airborne terminal operates at the original uplink transmission power.

[0086] In some embodiments, the preset interference condition includes at least one of the following: when the interference intensity is greater than the interference threshold, the number of interfered ground IMT base stations is greater than or equal to a preset number threshold; when the interference intensity is greater than the interference threshold, the number of interfered ground IMT base stations is within a preset number range.

[0087] It should be noted that the preset interference condition may include at least one preset quantity threshold, may include at least one preset quantity range, or may include both at least one preset quantity threshold and at least one preset quantity range. The specific type of the preset interference condition is not limited in the embodiments of the present disclosure.

[0088] Exemplarily, the preset interference condition includes at least one preset quantity threshold, the preset quantity thresholds are respectively a first preset quantity threshold and a second preset quantity threshold, the uplink transmission power corresponding to the first preset quantity threshold is a first uplink transmission power transmission, and the uplink transmission power corresponding to the second preset quantity threshold is a second uplink transmission power transmission.

[0089] If the number of the interfered terrestrial IMT base stations is greater than or equal to a first preset number threshold when the interference intensity is greater than the interference threshold, controlling the uplink transmission power of the ATG airborne terminal to transmit at a first uplink transmission power;

[0090] If the number of the interfered ground IMT base stations is less than a first preset number threshold and greater than or equal to a second preset number threshold when the interference intensity is greater than the interference threshold, the uplink transmission power of the ATG airborne terminal is controlled to be transmitted at the second uplink transmission power, wherein the first preset number threshold is greater than the second preset number threshold, and the first uplink transmission power is less than the second uplink transmission power.

[0091] In some embodiments, determining the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter includes: obtaining the number of interfered ground IMT base stations; querying a preset correspondence table according to the number of interfered ground IMT base stations to obtain the uplink transmission power corresponding to the number of interfered ground IMT base stations, wherein the correspondence table is used to indicate the correspondence between the number of interfered ground IMT base stations and the uplink transmission power.

[0092] Before querying the preset correspondence table, a correspondence table is constructed to indicate the correspondence between the number of interfered ground IMT base stations and the uplink transmission power. The correspondence table is stored on the ATG airborne terminal, and the uplink transmission power is the uplink transmission power that the ATG airborne device can transmit without affecting the normal use of the public network. For example, based on the number of interfered ground IMT base stations when the interference intensity in the target interference area is greater than the interference threshold, the uplink transmission power corresponding to the number of interfered ground IMT base stations is queried.

[0093] In some embodiments, determining the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter includes: obtaining the number of interfered terrestrial IMT base stations; and determining the uplink transmission power corresponding to the number of interfered terrestrial IMT base stations based on a pre-fitted function relationship.

[0094] Exemplarily, the pre-fitted functional relationship is a linear function equation, the independent variable is the number of interfered ground IMT base stations when the interference intensity is greater than the interference threshold, and the dependent variable is the uplink transmission power. The uplink transmission power is obtained by inputting the number of interfered ground IMT base stations when the interference intensity in the target interference area is greater than the interference threshold into the linear function equation, and the ATG airborne terminal operates with the obtained uplink transmission power, thereby reducing the impact on the public network and ensuring the normal use of the public network.

[0095] In some embodiments, determining the uplink transmission power of the ATG airborne terminal corresponding to the interference parameter includes: obtaining the number of interfered ground IMT base stations; and determining the uplink transmission power corresponding to the number of interfered ground IMT base stations when the interference intensity is greater than the interference threshold based on a pre-trained transmission power prediction model.

[0096] Exemplarily, the pre-trained transmission power prediction model is a neural network model. The number of interfered ground IMT base stations when the interference intensity in the target interference area is greater than the interference threshold is input into the neural network model. The neural network model outputs the uplink transmission power corresponding to the number of interfered ground IMT base stations when the interference intensity is greater than the interference threshold. The ATG airborne terminal operates with the obtained uplink transmission power, thereby reducing the impact on the public network and ensuring the normal use of the public network.

[0097] The solution of the present disclosure is described in detail below with reference to specific examples.

[0098] Embodiment 1:

[0099] For example, the interference parameters are evaluated by the ATG airborne terminal. The ATG airborne terminal receives the antenna parameters of the affected ground IMT base station sent by the ground IMT base station in the target interference area through the ATG base station. The ATG airborne terminal obtains the flight parameters of the ATG airborne terminal. The ATG airborne terminal obtains the interference parameters based on the flight parameters and the antenna parameters. The interference parameters include the interference intensity of the uplink interference of the ground IMT base station and the number of interfered ground IMT base stations.

[0100] The preset interference condition includes that when the interference intensity is greater than the interference threshold, the number of interfered ground IMT base stations is greater than or equal to the preset number threshold; the preset number threshold includes a first preset number threshold, a second preset number threshold, a third preset number threshold and a fourth preset number threshold, the first preset number threshold is greater than the second preset number threshold, the second preset number threshold is greater than the third preset number threshold, and the third preset number threshold is greater than the fourth preset number threshold.

[0101] When the number of interfered terrestrial IMT base stations is between the first preset number threshold and the second preset number threshold (including the case where the number of interfered terrestrial IMT base stations is equal to the first preset number threshold), the ATG airborne terminal operates at the first uplink transmission power; when the number of interfered terrestrial IMT base stations is between the second preset number threshold and the third preset number threshold (including the case where the number of interfered terrestrial IMT base stations is equal to the second preset number threshold), the ATG airborne terminal operates at the second uplink transmission power; when the number of interfered terrestrial IMT base stations is between the third preset number threshold and the fourth preset number threshold (including the case where the number of interfered terrestrial IMT base stations is equal to the third preset number threshold), the ATG airborne terminal operates at the third uplink transmission power; when the number of interfered terrestrial IMT base stations is greater than the first preset number threshold, the ATG airborne terminal causes relatively large interference to the terrestrial IMT base stations, and the ATG airborne terminal stops working; when the number of interfered terrestrial IMT base stations is less than or equal to the fourth preset number threshold, the ATG airborne terminal causes relatively small interference to the terrestrial IMT base stations and does not affect the use of the public network, and the ATG airborne terminal operates at the original uplink transmission power.

The interference parameter includes the interference intensity of the uplink interference of the terrestrial IMT base station and the number of interfered terrestrial IMT base stations.

[0104] In Table 1, x represents the number of interfered terrestrial IMT base stations. When 800 < x ≤ 1000, the ATG airborne terminal operates at an uplink transmission power of 20 dBm; when 600 < x ≤ 800, the ATG airborne terminal operates at an uplink transmission power of 21 dBm; when 400 < x ≤ 600, the ATG airborne terminal operates at an uplink transmission power of 22 dBm; when 200 < x ≤ 400, the ATG airborne terminal operates at an uplink transmission power of 23 dBm; when x is greater than 1000, the ATG airborne terminal causes relatively large interference to the terrestrial IMT base stations, and the ATG airborne terminal stops working; when x is less than or equal to 200, the ATG airborne terminal causes relatively small interference to the terrestrial IMT base stations and does not affect the use of the public network, and the ATG airborne terminal operates at the original uplink transmission power.

[0105] The preset interference condition includes that when the interference intensity is greater than the interference threshold, the number of the interfered ground IMT base stations is within a preset number range. By querying the corresponding relationship table, the corresponding uplink transmission power is obtained. The corresponding relationship table is used to indicate the correspondence between the number of interfered ground IMT base stations and the uplink transmission power. Table 1 shows the correspondence between the preset number range and the uplink transmission power.

[0107] Preset quantity range Uplink transmit power 800<x≤1000 20dBm 600<x≤800 21dBm 400<x≤600 22dBm 200<x≤400 23dBm
