[0019] To make the skilled in the art better understand the technical solutions of the present application, the technical solutions provided by the present application are described in detail below in combination with the drawings.

[0020] In the following, example embodiments will be described more fully with reference to the accompanying drawings, in which example embodiments can be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0021] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0022] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0023] In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets as each other and can be combined with each other, without conflict.

[0024] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present application, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0025] With the demand of civil aviation passengers in China for internet connection service on the plane, air-to-ground communication (ATG) as an important means of internet connection on the plane is concerned by all parties. The ATG air-to-ground communication system is to establish an air-ground communication link between the ground and the aircraft cabin by deploying ground special base stations along the route, using customer premise equipment (CPE) and ground special base stations, so that passengers can access the Internet in the cabin through wireless local area network access. However, when the aircraft is in the location, the transmission power will cause strong interference to the public network communication near the ground of the route, which is an urgent problem to be solved for the air-to-ground communication system. The problem mainly includes two parts: the transmission power is not allowed at low altitude, and the power at high altitude needs to consider the air-to-ground communication and the interference to the ground public network base station.

[0026] In the related art, to solve the above two problems, the following methods are usually used:

[0027] First, manually control the device switch of the aircraft onboard communication equipment to ensure that the transmission power cannot be emitted below a certain height. This process must rely on manual control and cannot be automatically controlled.

[0028] Second, use the positioning information of the global positioning system (GPS) to determine the height of the aircraft. When the height of the aircraft reaches a certain height, the radio frequency switch of the onboard communication equipment is automatically turned on. However, the calculation is for absolute height, and in plateau areas, the height from the ground will be misjudged, and the transmission power will be emitted at ground level or low altitude. This leads to the fact that this method can be used in plain areas, but manual control is still needed in plateau areas.

[0029] From the above control process of the onboard communication equipment, it can be seen that the current control of the onboard communication equipment needs to rely on manual control, and it cannot accurately suppress the interference of the onboard communication equipment to the base station, so the accuracy of suppressing the interference of the onboard communication equipment to the base station is low.

[0030] Based on this, the embodiment of the present application provides a control method of an airborne radio frequency module, a sending method and equipment of a station map. The airborne communication equipment receives the station map sent by the ground management server. The station map includes interference association information of a target network side equipment. The target network side equipment is a network side equipment at the position of the airborne communication equipment. The interference association information is associated with the interference of the airborne communication equipment to the target network side equipment. The airborne communication equipment controls the airborne radio frequency module based on the interference association information to suppress the interference of the airborne communication equipment to the target network side equipment. In this way, since the interference association information is associated with the interference of the airborne communication equipment to the target network side equipment, the airborne equipment can suppress the interference of the airborne communication equipment to the target network side equipment and improve the accuracy of suppressing the interference of the airborne communication equipment to the target network side equipment when controlling the airborne radio frequency module based on the interference association information of the target network side equipment.

[0031] The embodiment of the present application is further described below with reference to the accompanying drawings.

[0032] As shown in FIG. 1, the ground-air communication system provided by the embodiment of the present application includes a first network side equipment 10, a ground management server 20, an airborne communication equipment 30 and an airplane.

[0033] The ground management server 20 can be connected with the first network side equipment 10 through a cable. The first network side equipment 10 can be wirelessly connected with the airborne communication equipment 30. The airborne communication equipment 30 is connected with the airplane through a cable.

[0034] The first network side equipment 10 can be a network side equipment specially used for providing communication service for the airborne communication equipment 30. In some embodiments, the first network side equipment 10 can be a route dedicated base station, which is a base station specially used for providing communication service for the airborne communication equipment 30.

[0035] The ground management server 20 is used for obtaining interference association information of network side equipment at each position on the ground, generating a station map based on the interference association information, and transmitting the station map to the first network side equipment 10.

[0036] The network side equipment can be a ground dedicated base station or a public network base station. The public network base station is a base station used for providing communication service for other equipment except the airborne communication equipment 30. The other equipment can include a mobile phone terminal, a vehicle-mounted terminal, a smart wearable device and a portable computer, etc.

[0037] The airborne communication device 30 is an electronic device for communication on the airplane, which can receive the site map sent by the ground management server 20 through the first network side device 10, and control the airborne radio frequency module based on the interference correlation information of the target network side device in the site map, so as to suppress the interference of the airborne radio frequency module to the target network side device.

[0038] In some embodiments, the airborne communication device 30 can include a site map acquisition module 31, an airplane state acquisition module 32, a radio frequency and power control module 33, and an airborne radio frequency module 34. The site map acquisition module 31 is configured to acquire the site map sent by the ground management server 20 through the first network side device 10. The airplane state acquisition module 32 is configured to detect the state of the airplane wheels, i.e., whether the airplane wheels are off the ground. The radio frequency and power control module 33 is configured to control the airborne radio frequency module 34, such as turning on or off the airborne radio frequency module 34, or adjusting the transmission power of the airborne radio frequency module 34. The airborne radio frequency module 34 is configured to perform wireless communication with the first network side device 10.

[0039] Those skilled in the art can understand that the structure of the air-ground communication system shown in FIG. 1 does not constitute a limitation on the embodiments of the present application, and can include more or fewer components than those shown, or combine certain components, or different component arrangements.

[0040] Based on the above air-ground communication system, the following embodiments of the control method of the airborne radio frequency module are proposed.

[0041] Please refer to FIG. 2, which is a flowchart of the control method of the airborne radio frequency module according to the embodiments of the present application. The method can be applied to the airborne communication device in the air-ground communication system, and the airborne communication device includes the airborne radio frequency module. As shown in FIG. 2, the control method of the airborne radio frequency module can include, but is not limited to, the following steps S201 and S202.

[0042] Step S201, receiving the site map sent by the ground management server.

[0043] In this step, the site map includes the interference correlation information of the target network side device.

[0044] The target network side device can include at least one of a first network side device and a second network side device. The first network side device is a network side device specially used for providing communication services for the airborne communication device, for example, the first network side device can be a route dedicated base station, etc. The second network side device is a network side device used for providing communication services for devices other than the airborne communication device, for example, the second network side device can be a public network base station, and the public network base station is used for providing communication services for electronic devices such as ground mobile phone terminals, vehicle-mounted terminals, smart wearable devices, and portable computers, etc.

[0045] The site map can be obtained by the ground management server before step 201, and the interference correlation information of the target network side device is generated according to a specific format agreed by the ground management server and the airborne communication device, and the site map including the interference correlation information is generated.

[0046] For example, in the case of the target network side device being the first network side device (such as a route dedicated base station), the ground management server can obtain the interference correlation information of the first network side device, and generate a first site map (such as a route dedicated base station site map) according to a specific format agreed by the ground management server and the airborne communication device. Or, in the case of the target network side device being the second network side device (such as a public network base station), the ground management server can obtain the interference correlation information of the second network side device, and generate a second site map (such as a public network base station site map) according to a specific format agreed by the ground management server and the airborne communication device.

[0047] The interference correlation information can be any information associated with the interference of the airborne communication device to the target network side device, that is, the change of the interference correlation information has an influence on the interference of the airborne communication device to the target network side device.

[0048] In some embodiments, in the case of the target network side device being the first network side device, the interference correlation information can include at least one of a frequency point, a longitude, a latitude, a height, and an antenna angle. In the case of the target network side device being the second network side device, the interference correlation information can include at least one of a frequency point, a longitude, a latitude, a height, an antenna angle, a site traffic load, a site average noise floor, an allowed noise floor lifting value, and a specified air area that cannot emit power.

[0049] The ground management server generates the site map, which can be generated when the ground management server arrives at the first preset period, so that the ground management server can periodically update the site map, and the accuracy of the site map is improved.

[0050] The first preset period can be set according to actual needs, for example, the first preset period can be set to half an hour, one hour or two hours, etc.

[0051] The ground management server can actively send the site map to the airborne communication device through the first network side device.

[0052] In some embodiments, the ground management server actively sends the site map to the airborne communication device through the first network side device, which can include: the ground management server periodically sends a location request to the airborne communication device through the first network side device; the airborne communication device sends location information of the location where the airborne communication device is located to the ground management server through the first network side device in response to the location request; the ground management server determines a target network side device associated with the location information based on the received location information; and the ground management server sends a site map including interference association information of the target network side device to the ground management server through the first network side device.

[0053] The target network side device associated with the location information can be a communication service area of the target network side device covering a location corresponding to the location information (i.e. the location of the aircraft).

[0054] Alternatively, the ground management server can actively send the site map to the airborne communication device.

[0055] The airborne communication device actively requests the ground management server to send the site map, which can be that the airborne communication device sends a target request to the ground management server when a second preset period arrives; and the airborne communication device receives the site map sent by the ground management server in response to the target request, so that the airborne communication device can obtain the site map more timely.

[0056] The target request can carry location information of the aircraft where the airborne communication device is located, and be used to instruct the ground management server to feed back a site map associated with the location information to the airborne communication device. When the ground management server receives the target request, the ground management server can determine a target network side device associated with the location information in response to the target request, and send a site map including interference association information of the target network side device to the airborne device.

[0057] The second preset period can be set according to actual needs, for example, the first preset period can be set to half an hour, one hour or two hours, etc. It should be noted that the second preset period can be the same as the first preset period, or different from the first preset period, which is not limited herein.

[0058] It should be noted that, since the position of the aircraft is quickly moving during flight, the target network side device associated with the position is also constantly changing. For example, in the case where the target network side device is the first network side device, the first network side device can be a first airport dedicated base station that is in communication connection with the airborne communication device at the first position. At the second position, the first network side device is switched to a second airport dedicated base station that is in communication connection with the airborne communication device.

[0059] In addition, since the airborne communication device is in wireless communication connection with the ground management server through the first network side device, in order to prevent instability in wireless communication from causing the airborne communication device to fail to connect with the ground management server, an initial site map can be preloaded into the airborne communication device. The initial site map can be manually imported into the airborne communication device by the maintenance personnel, and in the case where the airborne communication device receives a site map sent by the ground management server, the initial site map is updated by the received site map.

[0060] For example, the first network side device is an airline dedicated base station, and the second network side device is a public network base station. As shown in FIG. 2, in the case where the airborne communication device needs to obtain the site map of the airline dedicated base station or the public network base station, the site map acquisition module of the airborne communication device is preloaded with an initial site map, and it detects whether the update period (i.e., the second preset period) is reached. If the update period is reached, the site map acquisition module can initiate a first request to the ground management server to query the version number of the site map of the airline dedicated base station or the public network base station. The ground management server returns the version number of the site map to the site map acquisition module in response to the first request. The site map acquisition module determines whether the site map is updated based on the version number of the site map fed back by the ground management server and the version number of the initial site map. In the case where it is determined that the site map is updated, the site map acquisition module initiates a second request to the ground management server to query the site map of the dedicated base station or the public network base station. The ground management server returns a new site map to the site map acquisition module in response to the second request. The site map acquisition module updates the initial site map based on the site map returned by the site map acquisition module.

[0061] In step S202, the airborne radio frequency module is controlled based on the interference association information to suppress the interference of the airborne radio frequency module to the target network side device.

[0062] In the step, the airborne radio frequency module is controlled based on the interference correlation information. The airborne communication device can determine whether the interference generated by the airborne communication device to the target network side device affects the operation of the target network side device based on the interference correlation information. If the interference generated by the airborne communication device to the target network side device affects the operation of the target network side device, the airborne radio frequency module is controlled to suppress the interference generated by the airborne radio frequency module to the target network side device.

[0063] The purpose of controlling the airborne radio frequency module is to suppress the interference generated by the airborne radio frequency module to the target network side device. In the case that the target network side device is a first network side device, the airborne radio frequency module is controlled to be turned off, for example, during the process of taking off, the interference generated by the airborne radio frequency module can be avoided to affect the normal operation of the route dedicated base station. In the case that the target network side device is a second network side device, the transmission power of the airborne radio frequency module is controlled to be reduced, for example, during the process of flying in the high altitude, the interference generated by the airborne radio frequency module can be avoided to affect the normal operation of the public network base station.

[0064] In the embodiments of the present application, the airborne communication device receives a site map sent by a ground management server. The site map includes interference correlation information of a target network side device. The target network side device is a network side device at the location of the airborne communication device. The interference correlation information is associated with the interference generated by the airborne communication device to the target network side device. The airborne communication device controls the airborne radio frequency module based on the interference correlation information to suppress the interference generated by the airborne radio frequency module to the target network side device. In this way, since the interference correlation information is associated with the interference generated by the airborne communication device to the target network side device, the airborne communication device can suppress the interference generated by the airborne communication device to the target network side device and improve the accuracy of suppressing the interference generated by the airborne communication device to the target network side device when the airborne radio frequency module is controlled based on the interference correlation information of the target network side device.

[0065] In some embodiments, the interference correlation information includes a first height of a first network side device. The first network side device is a network side device that provides communication services to the airborne communication device. Controlling the airborne radio frequency module based on the interference correlation information can include:

[0066] Determining a height above ground of the airborne communication device based on the first height and a second height at which the airborne communication device is located.

[0067] Controlling a working state of the airborne radio frequency module based on the height above ground. The working state includes turning on or turning off.

[0068] The first height can be understood as the altitude of the first network side device. Since the first network side device is usually fixed, the first height can be the lowest altitude of the first network side device, the central altitude of the first network side device, or the highest altitude of the first network side device.

[0069] The second height can be understood as the altitude of the aircraft. Since the altitude of the aircraft is constantly changing during the take-off process of the aircraft, the second height can be detected in real time by the height detection module in the airborne communication device.

[0070] Based on the first height and the second height of the airborne communication device, the height above ground of the airborne communication device can be determined by subtracting the first height from the second height.

[0071] Based on the height above ground, the working state of the airborne radio frequency module can be controlled. During the take-off process, the airborne radio frequency module can be controlled to be closed when the aircraft is detected to be moving. When the height above ground is less than a first preset height threshold, the airborne radio frequency module remains in a closed state. When the height above ground is greater than the first preset height threshold, the airborne radio frequency module is controlled to be opened.

[0072] During the landing process, based on the height above ground, the working state of the airborne radio frequency module can be controlled. When the height above ground of the aircraft is detected to be less than the first preset height threshold, the airborne radio frequency module is controlled to be switched from an opened state to a closed state. When the height above ground continues to decrease until the aircraft stops moving, the airborne radio frequency module remains in a closed state. Until the aircraft completely stops, the airborne radio frequency module is controlled to be opened again.

[0073] Based on the height above ground, the working state of the airborne radio frequency module can be controlled. When the wheels of the aircraft where the airborne communication device is located leave the ground and the height above ground is less than a second preset height threshold, the airborne radio frequency module is controlled to be closed. When the wheels of the aircraft where the airborne communication device is located leave the ground and the height above ground is greater than or equal to the second preset height threshold, the airborne radio frequency module is controlled to be opened, thereby realizing the control of the opening or closing of the airborne radio frequency module in combination with the wheel state and the height above ground.

[0074] For example, during the take-off process of the aircraft, it can be determined whether the wheels of the aircraft are located on the ground. When the wheels are located on the ground, the airborne radio frequency module remains opened. When it is determined that the wheels of the aircraft leave the ground, the airborne radio frequency module is closed. After the airborne radio frequency module is closed, if it is monitored that the height above ground is less than the second preset height threshold, the airborne radio frequency module remains closed. If it is monitored that the height above ground is greater than or equal to the second preset height threshold, the airborne radio frequency module is controlled to be opened.

[0075] It should be noted that the first preset height threshold and the second preset height threshold can be values set according to actual needs, and the first preset height threshold and the second preset height threshold can be the same or different.

[0076] Exemplarily, taking the first network side device as the route dedicated base station and the second network side device as the public network base station as an example, as shown in FIG. 3, in the process of taking off the airplane (at this time, the airplane is moving), the radio frequency and power control module of the airborne communication device can initiate a third request for querying the airplane state (i.e., the wheel state) to the airplane state acquisition module, the airplane state acquisition module queries the airplane state in response to the third request and returns to the radio frequency and power control module, the radio frequency and power control module determines whether the airplane is in the landing state (i.e., whether the wheels leave the ground) according to the airplane state, if it is determined that the wheels are in the landing state (i.e., the wheels do not leave the ground), the radio frequency module is controlled to be closed; if it is determined that the wheels are not in the landing state (i.e., the wheels leave the ground), the radio frequency and power control module initiates a second request for querying the site map of the route dedicated base station to the site map acquisition module, the site map acquisition module returns the site map of the route dedicated base station to the radio frequency and power control module in response to the second request; the radio frequency and power control module combines the current position of the airplane (including the second height) and the site position of the route dedicated base station (including the first height) to calculate the height from the ground of the airplane; the radio frequency and power control module determines whether the height from the ground is greater than a threshold (i.e., the second preset height threshold), if the height from the ground is less than the threshold, the radio frequency module is continuously controlled to be closed; if the height from the ground is greater than or equal to the threshold, the radio frequency module is controlled to be opened.

[0077] In this embodiment, the airborne communication device can determine the height from the ground according to the second height where the airborne communication device is located and the first height where the first network side device is located, and control the opening or closing of the airborne radio frequency module based on the height from the ground, so as to realize the suppression of the interference generated by the airborne communication device to the first network side device.

[0078] In some embodiments, the interference association information is information of the second network side device, and the second network side device is a network side device providing communication services to devices other than the airborne communication device.

[0079] The above control of the airborne radio frequency module based on the interference association information includes:

[0080] Based on the interference association information, the interference result between the airborne radio frequency module and the second network side device is determined, and the interference result is used to indicate whether the interference generated by the airborne radio frequency module to the second network side device meets a preset interference condition;

[0081] In a case where the interference result indicates that the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition, the transmitting power of the airborne radio frequency module is controlled.

[0082] The preset interference condition can be set according to the anti-interference capability of the second network side device. In a case where the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition, it indicates that the interference generated by the airborne radio frequency module has affected the normal operation of the second network side device. At this time, the interference generated by the airborne radio frequency module to the second network side device needs to be suppressed by controlling the transmitting power of the airborne radio frequency module.

[0083] It should be noted that in a case where the interference result indicates that the interference generated by the airborne radio frequency module to the second network side device does not satisfy the preset interference condition, the airborne communication device can not adjust the transmitting power of the airborne radio frequency module, that is, the transmitting power of the airborne radio frequency module remains at the transmitting power for normal communication with the first network side device.

[0084] In the embodiment, during the takeoff or flight of the aircraft, the airborne communication device can determine the interference result between the airborne radio frequency module and the second network side device based on the interference-related information of the second network side device, and in a case where the interference result indicates that the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition, the transmitting power of the airborne radio frequency module is controlled to suppress the interference generated by the airborne radio frequency module to the second network side device (such as a public network base station).

[0085] The interference-related information of the second network side device can be any information capable of representing the interference generated by the airborne radio frequency module to the second network side device.

[0086] In some embodiments, the interference-related information of the second network side device can include at least one of the following:

[0087] The third height of the second network side device;

[0088] The first antenna angle of the second network side device;

[0089] The service load of the second network side device.

[0090] The third height of the second network side device can be understood as the altitude of the second network side device. Since the second network side device is usually fixed, the third height of the second network side device can be the lowest altitude of the second network side device, the central altitude of the second network side device, or the highest altitude of the second network side device.

[0091] The first antenna angle of the second network-side device can be an azimuth angle of an antenna of the second network-side device, and can also include a downtilt angle of the antenna of the second network-side device, and the like.

[0092] The service load of the second network-side device can be a service amount of the second network-side device in providing a communication service.

[0093] In the embodiment, the interference-related information of the second network-side device can include at least one of the third height, the first antenna angle, and the service load, so that the manner of determining the interference result is more flexible.

[0094] In some embodiments, in a case where the interference result indicates that the interference generated by the airborne radio frequency module on the second network-side device satisfies the preset interference condition, the transmission power of the airborne radio frequency module is controlled, including at least one of the following:

[0095] In a case where a difference between the second height at which the airborne communication device is located and the third height is less than or equal to a preset height threshold (for the sake of distinction, referred to as a "third preset height threshold" here), the transmission power of the airborne radio frequency module is reduced;

[0096] In a case where the first antenna angle and the second antenna angle of the airborne communication device have an overlapping region, the transmission power of the airborne radio frequency module is reduced;

[0097] In a case where the service load of the second network-side device is greater than or equal to a preset load threshold, the transmission power of the airborne radio frequency module is reduced.

[0098] In a case where the interference-related information of the second network-side device includes the third height of the second network-side device, the airborne communication device can determine whether a difference between the second height at which the airborne communication device is located and the third height is less than or equal to the third preset height threshold, and if the difference between the second height and the third height is less than or equal to the third preset height threshold, it is determined that the interference generated by the airborne radio frequency module on the second network-side device satisfies the preset interference condition, that is, the interference result indicates that the interference generated by the airborne radio frequency module on the second network-side device satisfies the preset interference condition, and at this time, the transmission power of the airborne radio frequency module is controlled to be reduced to reduce the interference generated by the airborne radio frequency module on the second network-side device.

[0099] It should be noted that the third preset height threshold can be a value set according to actual needs or experience, for example, as shown in FIG. 4, the third preset height threshold can be set to 5000 meters, at this time, if the height of the airborne communication device is less than or equal to 6000 meters, it is determined that the interference generated by the airborne radio frequency module to the public network base station satisfies the preset interference condition, that is, the interference generated by the airborne radio frequency module has affected the normal work of the public network base station, at this time, the normal power transmission is performed according to the site position of the route dedicated base station; or, the third height threshold can also be set to 4500 meters, at this time, if the height of the airborne communication device is less than or equal to 4500 meters, it is determined that the interference generated by the airborne radio frequency module to the public network base station satisfies the preset interference condition, that is, the interference generated by the airborne radio frequency module has affected the normal work of the public network base station, and the like, which are not limited herein.

[0100] In a case where the interference-related information of the second network side device includes a first antenna angle of the second network side device, the airborne communication device can determine whether the first antenna angle and a second antenna angle of the airborne communication device have an overlapping area, and if the first antenna angle and the second antenna angle of the airborne communication device have the overlapping area, it is determined that the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition, that is, the interference result indicates that the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition, at this time, the transmission power of the airborne radio frequency module is controlled to be reduced to reduce the interference generated by the airborne radio frequency module to the second network side device.

[0101] In a case where the interference-related information of the second network side device includes a service load of the second network side device, the airborne communication device can determine whether the service load of the second network side device is greater than or equal to a preset load threshold, and if the service load of the second network side device is greater than or equal to the preset load threshold, it is determined that the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition, that is, the interference result indicates that the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition, at this time, the transmission power of the airborne radio frequency module is controlled to be reduced to reduce the interference generated by the airborne radio frequency module to the second network side device.

[0102] It should be noted that the above reducing the transmission power of the airborne radio frequency module can be that the airborne communication device directly controls the transmission power of the airborne radio frequency module to be reduced once it is determined that the interference result indicates that the interference generated by the airborne radio frequency module to the second network side device satisfies the preset interference condition.

[0103] In addition, the reducing the transmission power of the airborne radio frequency module can be reducing the transmission power of the airborne radio frequency module according to a preset adjustment amplitude; or the adjustment amplitude of the transmission power of the airborne radio frequency module can be determined according to at least one of the third height, the first antenna angle and the service load, and then the transmission power of the airborne radio frequency module is reduced according to the determined adjustment amplitude.

[0104] In the embodiment, whether the interference generated by the airborne radio frequency module to the second network side device meets the preset interference condition can be determined according to at least one of the third height, the first antenna angle and the service load of the two network side devices respectively, and the transmission power of the airborne radio frequency module is reduced when the interference meets the preset interference condition, so that the embodiment is more flexible.

[0105] In some embodiments, the reducing the transmission power of the airborne radio frequency module comprises:

[0106] According to the second height, the position information of the airborne communication device and the transmission power of the airborne radio frequency module, a first noise floor lifting value of the second network side device under the interference of the airborne communication device is determined.

[0107] In a case where the first noise floor lifting value is greater than or equal to a target noise floor lifting value, the transmission power of the airborne radio frequency module is reduced, wherein the target noise floor lifting value is a current allowed noise floor lifting value of the second network side device under the interference of the airborne communication device.

[0108] In some embodiments, the determining the first noise floor lifting value of the second network side device under the interference of the airborne communication device according to the second height, the position information of the airborne communication device and the transmission power of the airborne radio frequency module can comprise: determining a noise floor lifting value having a preset mapping relationship with the second height, the position information of the airborne communication device and the transmission power of the airborne radio frequency module as the first noise floor lifting value of the second network side device under the interference of the airborne communication device.

[0109] The target noise floor lifting value can be obtained based on the site map, and in some embodiments, the site map further comprises an allowed noise floor lifting value of the second network side device and a current second noise floor lifting value of the second network side device, and before the reducing the transmission power of the airborne radio frequency module in the case where the first noise floor lifting value is greater than or equal to the target noise floor lifting value, the difference between the allowed noise floor lifting value and the second noise floor lifting value is determined as the target noise floor lifting value.

[0110] In this embodiment, the airborne communication device determines that the interference result indicates that the interference generated by the airborne radio frequency module to the second network side device meets the preset interference condition, further determines whether the first floor noise lifting value of the second network side device under the interference of the airborne communication device is greater than or equal to the target floor noise lifting value, and reduces the transmission power of the airborne radio frequency module when the first floor noise lifting value is greater than or equal to the target floor noise lifting value, so that the operation of controlling the transmission power of the airborne radio frequency module to be reduced is more accurate.

[0111] For example, the first network side device is an air route dedicated base station, and the second network side device is a public network base station, as shown in FIG. 5, the radio frequency and power control module can query the air route dedicated base station site map and the public network base station site map from the site map acquisition module respectively, and the site map acquisition module feeds back the air route dedicated base station site map and the public network base station site map to the radio frequency and power control module; the radio frequency and power control module determines whether the distance between the public network base station and the aircraft exceeds the threshold according to the site map of the public network base station, if the distance between the public network base station and the aircraft exceeds the threshold (i.e. the difference between the second height and the third height is greater than the preset height threshold), the normal power transmission is performed according to the site position of the air route dedicated base station;

[0112] If the distance between the public network base station and the aircraft does not exceed the threshold, for example, as shown in FIG. 6, the threshold is 5000 meters, and the current distance between the airborne communication device and the public network base station is 4500 meters, it is further determined whether there is an overlapping area between the current antenna angle of the airborne communication device and the antenna angle of the public network base station, if there is no overlapping area, the normal power transmission is performed according to the site position of the air route dedicated base station;

[0113] If there is an overlapping area, it is further determined whether the load of the public network base station is lower than the threshold (i.e. the preset load threshold), if the load of the public network base station is lower than the threshold, the normal power transmission is performed according to the site position of the air route dedicated base station; otherwise, the transmission power is adjusted according to the current floor noise of the public network base station and the allowable floor noise, for example, as shown in FIG. 6, the allowable floor noise lifting value (i.e. the allowable floor noise lifting value) of the current public network base station can be calculated; and the preset data including the floor noise lifting influence value (i.e. the first floor noise lifting value) of the airborne communication device on the public network base station under different heights, positions and different transmission powers is obtained, and then the maximum transmission power of the radio frequency module is adjusted according to the allowable floor noise lifting value of the current public network base station and the preset data.

[0114] Based on the above air-ground communication system, the following embodiment of the sending method of the site map is proposed.

[0115] Please refer to FIG. 7, which is a flowchart of a method for controlling an airborne radio frequency module according to an embodiment of the present application. The method can be applied to a ground management server in a ground-air communication system. As shown in FIG. 7, the method for controlling the airborne radio frequency module can include, but is not limited to, the following steps:

[0116] In step S701, a site map is sent to an airborne communication device. The site map includes interference correlation information of a target network side device. The target network side device is a network side device at a location of the airborne communication device. The interference correlation information is associated with interference caused by the airborne communication device to the target network side device.

[0117] In step S702, the airborne communication device controls the airborne radio frequency module based on the interference correlation information to suppress interference caused by the airborne radio frequency module to the target network side device.

[0118] In the embodiment, the site map can be generated by the ground management server before step S701. The ground management server obtains the interference correlation information of the target network side device and generates the site map including the interference correlation information in a specific format agreed between the ground management server and the airborne communication device.

[0119] In some embodiments, the ground management server can generate the site map when a first preset period is reached. In this way, the ground management server can periodically update the site map to improve the accuracy of the site map.

[0120] The first preset period can be set according to actual needs. For example, the first preset period can be set to half an hour, one hour, two hours, etc.

[0121] For example, the first network side device is a route dedicated base station and the second network side device is a public network base station. As shown in FIG. 8, the ground management server can obtain site information of the route dedicated base station (i.e., interference correlation information of the first network side device), generate a route dedicated base station site map based on the site information of the route dedicated base station, and periodically update the route dedicated base station site map according to the site information of the route dedicated base station. In addition, the ground management server can obtain site information of the public network base station (i.e., interference correlation information of the second network side device), generate a public network base station site map based on the site information of the public network base station, and periodically update the public network base station site map according to the site information of the public network base station.

[0122] In step 701, the ground management server sends the site map to the airborne communication device. The ground management server can actively send the site map to the airborne communication device through the first network side device. The ground management server can periodically send a location request to the airborne communication device through the first network side device. The ground management server receives location information of a location where the airborne communication device is located, which is fed back by the airborne communication device in response to the location request. The ground management server determines a target network side device associated with the location information based on the location information. The ground management server sends the site map including interference association information of the target network side device to the ground management server through the first network side device.

[0123] Alternatively, in some embodiments, before step 701, the method can further include:

[0124] The ground management server receives a target request sent by the airborne communication device. The target request is sent by the airborne communication device when the airborne communication device arrives at the first preset period.

[0125] Step 701 can include:

[0126] In response to the target request, the ground management server sends the site map to the airborne communication device.

[0127] The target request can carry location information of an aircraft where the airborne communication device is located, and is used to instruct the ground management server to feed back a site map associated with the location information to the airborne communication device. When the ground management server receives the target request, the ground management server can determine a target network side device associated with the location information in response to the target request, and send a site map including interference association information of the target network side device to the airborne device.

[0128] The second preset period can be a time length set according to actual needs. For example, the first preset period can be set to half an hour, one hour, two hours, etc. It should be noted that the second preset period can be the same as the first preset period, or can be different from the first preset period, which is not limited herein.
