[0050] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0051] As described in the background, the related art air-ground broadband communication technology has the problem of high risk of communication interference. The inventors have found that the cause of this problem is that the air-ground broadband communication technology uses radio signals transmitted by ground base stations arranged along the flight route to provide high-bandwidth communication services to aircraft in the air, realizing air-ground interconnection. It can not only provide real-time transmission services for industry data for civil aviation users, but also provide in-flight Internet access services for passengers. China has a large land area, and domestic routes account for a high proportion. At present, the ground base station network of domestic telecom operators has a wide coverage area, mature technology, wide bandwidth, and high speed, providing good conditions for developing ATG air-ground communication systems. In the case of frequency reuse between ATG systems and operator ground networks, signal transmission in the air will inevitably interfere with the ground same-frequency system, so the signal transmission of the airborne device must ensure the optimal user service performance and the lowest interference risk. Therefore, the ATG airborne device must realize the functions of real-time spectrum resource configuration and transmission power adjustment, occupy the spectrum bandwidth in real time through on-board traffic statistics, judge the spectrum resources occupied by the ground same-frequency interference through the ground base station, and allocate spectrum resources for the ATG uplink and determine the real-time transmission power of the airborne device through a certain evaluation strategy.

[0052] Based on the above reasons, the present application provides an airborne device uplink resource configuration method, which aims to reduce the risk of communication interference.

[0053] In an exemplary embodiment, as shown in Figure 1 An airborne device uplink resource configuration method is provided, and the embodiment illustrates the method applied to a server. It should be understood that the method can also be applied to a terminal and can also be applied to a system including a terminal and a server and realized through the interaction of the terminal and the server. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. In the embodiment, the method includes the following steps:

[0054] Step S102, obtaining the traffic demand, the total number of base stations, and the same-frequency interference signals received by each base station in the air-ground broadband communication system.

[0055] The air-ground broadband communication system can be an ATG system, which refers to a network system that establishes high-speed wireless communication between ground base stations arranged along the flight route and aircraft (airborne devices), supports large-bandwidth data transmission, and meets the business needs of Internet access, real-time monitoring, etc. in the aviation scenario.

[0056] wherein the traffic demand can be the service usage of the user terminals onboard the aircraft, the data transmission volume that the system needs to carry, usually measured by throughput (e.g. Mbps / Gbps) or the number of connections, reflecting the bandwidth demand of the user or application to the uplink.

[0057] wherein the base stations can be ground fixed communication facilities responsible for wireless signal transceiving with the airborne devices, each covering a specific airspace, and the total number of which directly affects the system capacity and interference level.

[0058] wherein the uplink can be the one-way channel in the communication link that transmits data from the airborne device to the ground base station (the reverse is the downlink), which needs to allocate spectrum and power resources to ensure signal quality.

[0059] wherein the co-channel interference signal can be the interference signal caused by frequency reuse, i.e. the unintended energy superposition on the current base station uplink reception caused by signals from other co-channel transmitting sources (such as other ground systems, adjacent base stations or airborne devices).

[0060] Optionally, the server obtains the traffic demand, the total number of base stations and the co-channel interference signals received by each base station in the air-ground broadband communication system, so as to determine the uplink configuration requirement of the airborne device according to the traffic demand, and obtain the total number of base stations and the co-channel interference signals received by each base station, so as to understand the status of each base station as data support for subsequent resource configuration. It can be understood that the total number of base stations is obtained by the server according to the maximum uplink spectrum bandwidth of the carrier frequency band used by the air-ground broadband communication system, and according to the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) protocol.

[0061] In step S104, the number of demand base stations corresponding to the traffic demand is determined, and the disturbed base station information is determined according to the first comparison result between the preset uplink disturbed threshold and the co-channel interference signals of each base station.

[0062] wherein the number of demand base stations can be the theoretical calculation value according to the traffic demand, indicating the minimum number of base stations required to meet the capacity, which can be affected by coverage range, spectrum efficiency, etc.

[0063] wherein the preset uplink disturbed threshold can be the upper limit of the co-channel interference that the base station can tolerate (such as the signal-to-noise ratio threshold), and if the value exceeds this value, it is determined to be disturbed and the resource allocation needs to be adjusted.

[0064] wherein the disturbed base station information can include the location of the interfered base station, the number of interfered base stations, the interference strength, the affected services, etc.

[0065] Optionally, the server determines the total uplink throughput and the maximum capacity of a single base station according to the traffic demand and the information of each base station, and obtains the number of demand base stations corresponding to the traffic demand according to the ratio of the two. It can be understood that the total uplink throughput can be obtained according to the product of the number of user terminals on the aircraft and the average uplink rate of each user terminal, and the maximum capacity of a single base station can be calculated according to the frequency efficiency and available spectrum resources. Further, the server compares the preset uplink interference threshold with the co-channel interference signals of each base station in turn to obtain the first comparison result corresponding to each base station, and determines the interfered base station information from the information of all base stations according to the first comparison result corresponding to each base station.

[0066] In step S106, the resource configuration strategy of the airborne equipment uplink of the air-ground broadband communication system is determined according to the total number of base stations, the interfered base station information and the number of demand base stations.

[0067] The resource configuration strategy includes the spectrum resource configuration and the transmit power configuration for the airborne equipment. The spectrum resource configuration can be the frequency band or channel (such as the center frequency and the bandwidth) of the specific base station allocated to the airborne equipment, which needs to avoid co-channel interference and meet the traffic demand. The transmit power configuration can be the uplink transmit power of the airborne equipment, which is dynamically adjusted to balance the signal coverage (to ensure the communication quality) and the interference suppression (to reduce the impact on other stations).

[0068] Optionally, the server configures the spectrum resource and the transmit power of the airborne equipment uplink of the air-ground broadband communication system according to the total number of base stations, the interfered base station information and the number of demand base stations to obtain the resource configuration strategy.

[0069] In the above method for configuring the resource of the airborne equipment uplink, the traffic demand, the total number of base stations and the co-channel interference signals received by each base station in the air-ground broadband communication system are obtained to understand the traffic demand of the uplink, master the deployment scale of the base stations and the co-channel interference of each base station, and provide data support for subsequent resource configuration. The number of demand base stations corresponding to the traffic demand is further determined. The interfered base station information is determined according to the first comparison result between the preset uplink interference threshold and the co-channel interference signals of each base station, and the interfered base station and its information are located to lay the foundation for subsequent interference management. The resource configuration strategy of the airborne equipment uplink of the air-ground broadband communication system is determined according to the total number of base stations, the interfered base station information and the number of demand base stations. The resource configuration strategy includes the spectrum resource configuration and the transmit power configuration for the airborne equipment. The spectrum resource and the transmit power are dynamically adjusted in combination with the number of demand base stations and the actual interference of each base station, so as to improve the reliability and capacity of the uplink and reduce the risk of communication interference.

[0070] In an exemplary embodiment, the step S104 of determining the interfered base station information according to the first comparison result between the preset uplink interference threshold and the co-channel interference signal of each base station comprises:

[0071] The server filters the base stations corresponding to the co-channel interference signal greater than the preset uplink interference threshold from the base stations to obtain the interfered base stations, and obtains the information of the interfered base stations to obtain the interfered base station information.

[0072] The interfered base station can be a base station interfered by the co-channel interference signal.

[0073] Optionally, the server compares the co-channel interference signal of each base station with the preset uplink interference threshold in sequence to obtain the first comparison result of each base station, determines the base station with the first comparison result of the co-channel interference signal greater than the preset uplink interference threshold as the interfered base station, and obtains the information of the interfered base station, including the position of the interfered base station, the number of the interfered base stations, the interference strength, and the affected service data, to obtain the interfered base station information. It can be understood that the base station with the first comparison result of the co-channel interference signal less than or equal to the preset uplink interference threshold is a base station not interfered by the co-channel interference.

[0074] In the embodiment, by setting a reasonable preset uplink interference threshold, the interference signals are classified into two categories, the interfered base station is determined by using the first comparison result, the efficient identification and positioning of the interfered base station are realized, the basic support for interference management is provided, and the communication interference risk is further reduced.

[0075] In an exemplary embodiment, before the step S106 of determining the resource configuration strategy of the uplink of the airborne equipment of the air-ground broadband communication according to the total number of base stations, the interfered base station information, and the number of required base stations, the method further comprises:

[0076] According to the interfered base station information, the number of the interfered base stations and the positions of the interfered base stations are determined, and all the interfered base stations are disabled according to the positions of the interfered base stations.

[0077] The disabling processing can be puncturing processing, which means temporarily or permanently closing the uplink communication function of the interfered base station by software or hardware control means.

[0078] Optionally, according to the interfered base station information, the server determines the number of the interfered base stations and the positions of the interfered base stations, thereby positioning each interfered base station, and adopts the frequency band isolation, beam direction interference, time scheduling, or dynamic resource limitation, and the like, to disable all the interfered base stations, so as to isolate the normal base stations and the interfered base stations, and reduce the interference influence of the interfered base stations.

[0079] In the embodiment, the server determines the positions and the number of the interfered base stations according to the collected information of the interfered base stations. A variety of interference control strategies are adopted to disable the interfered base stations, so as to realize the isolation of the normal base stations and the interfered base stations, reduce the interference, improve the system health status and the communication quality, and further reduce the communication interference risk.

[0080] In an exemplary embodiment, as shown in Figure 2 Fig. 2, according to the total number of base stations, the information of the interfered base stations and the number of required base stations, a resource configuration strategy of the uplink of the airborne equipment of the ground-to-air broadband communication is determined, including the following steps S202 to S204. Wherein:

[0081] Step S202, determining a second comparison result between the sum of the number of the interfered base stations and the number of the required base stations and the total number of base stations.

[0082] Optionally, the server compares the sum of the number of the interfered base stations and the number of the required base stations with the total number of base stations to obtain the second comparison result, and measures whether the spectrum resources provided by the current base stations can meet the service requirements through the second comparison result.

[0083] Step S204, determining the resource configuration strategy of the uplink of the airborne equipment of the ground-to-air broadband communication according to the second comparison result.

[0084] Optionally, the server determines the resource configuration strategy of the uplink of the airborne equipment of the ground-to-air broadband communication corresponding to the spectrum resources provided by the current base stations according to the second comparison result. For example, if the sum is greater than the total number of base stations, it indicates that the spectrum resources provided by the base stations are insufficient or even cannot meet the service requirements, in which case the spectrum resources provided by the base stations should be allocated to the uplink of the airborne equipment, and the airborne equipment needs to increase the transmission power to compensate; if the sum is less than the total number of base stations, it indicates that the spectrum resources provided by the base stations are sufficient, in which case the spectrum resources with less interference can be selected from the spectrum resources provided by the base stations for allocation, and the transmission power can be dynamically allocated.

[0085] In the embodiment, different configuration schemes are adopted according to the second comparison result, which enhances the adaptability of the system to the changing environment and avoids the hard or static resource division, thereby improving the resource utilization efficiency.

[0086] In an exemplary embodiment, as shown in Figure 3 Fig. 2, step S204 determines the resource configuration strategy of the uplink of the airborne equipment of the ground-to-air broadband communication according to the second comparison result, including steps S302 to S306. Wherein:

[0087] Step S302, in the case that the second comparison result is that the sum of the number of the interfered base stations and the number of the demand base stations is less than the total number of the base stations, the candidate base stations except the interfered base stations are determined from all the base stations according to the interfered base station information.

[0088] The candidate base station can be a base station that has not suffered from the same frequency signal interference or has a low degree of the same frequency signal interference among all the base stations.

[0089] Optionally, in the case that the second comparison result is that the sum of the number of the interfered base stations and the number of the demand base stations is less than the total number of the base stations, it indicates that the spectrum resources provided by the base stations have a margin at this time, and the candidate base stations except the interfered base stations are determined from all the base stations according to the interfered base station information such as the position, the identifier and the like, and the spectrum resources provided by the candidate base stations can be used for configuring the uplink of the airborne device.

[0090] Step S304, the spectrum resource configuration is determined according to the distance between each candidate base station and the interfered base station and the number of the demand base stations.

[0091] Optionally, the server selects the candidate base station with a relatively far distance between each candidate base station and the interfered base station, thereby determining the candidate base station corresponding to the number of the demand base stations, and determining the spectrum resources provided by the candidate base station as the spectrum resource configuration of the airborne device. For example, the server acquires the relative distance between each candidate base station and the interfered base station within the current connectable range of the airborne device in real time during the flight of the aircraft, and preferentially selects the base station with the farthest relative distance from the interfered base station for connection.

[0092] Step S306, the transmission power configuration is determined according to the pre-constructed airborne transmission power configuration table.

[0093] The pre-constructed airborne transmission power configuration table can be a mapping relationship table constructed by the technician according to the corresponding relationship between the straight line distance between the airborne device and the base station and the transmission power of the airborne device.

[0094] Optionally, the server detects the straight line distance between the airborne device and the connected base station in real time during the flight of the aircraft, queries the pre-constructed airborne transmission power configuration table according to the straight line distance to determine the transmission power of the airborne device, thereby realizing the dynamic transmission power configuration for the airborne device.

[0095] If the sum of the number of disturbed base stations and the number of required base stations is less than the total number of base stations, the resources are sufficient, and there is room for optimization configuration. In all base stations, the base stations far away from the disturbed base stations are selected as candidate base stations. The candidate base stations far away from the disturbed base stations are selected to reduce the influence of the interference source. The candidate base stations meeting the number of required base stations are selected, and the spectrum resources of the candidate base stations are configured to the airborne equipment. The straight-line distance between the airborne equipment and the base station is measured in real time, the transmission power configuration table is built in advance, the transmission power of the airborne equipment is dynamically determined, the balance between energy efficiency and interference control is achieved.

[0096] In an exemplary embodiment, step S304 determines the spectrum resource configuration according to the distance between each candidate base station and the disturbed base station, and the number of required base stations, including:

[0097] The distances between each candidate base station and the disturbed base station are sorted to obtain a base station distance order table. According to the base station distance order table, the target base stations corresponding to the number of required base stations are determined from the candidate base stations, and the frequency range provided by the target base stations is configured as the spectrum resource.

[0098] The base station distance order table can be an identifier list of the candidate base stations arranged in descending or ascending order of distance.

[0099] The target base station can be a candidate base station with a relatively large distance selected to provide spectrum resources for the airborne equipment.

[0100] The frequency range refers to the minimum and maximum frequency limits of the wireless signal or communication system, which defines the frequency band interval of signal transmission, and in the embodiment, corresponds to the spectrum resource provided by the target base station.

[0101] Alternatively, there is at least one disturbed base station, so when determining the distance between each candidate base station and each disturbed base station, there are the following implementation forms. For example, for each candidate base station, the server takes the minimum distance, the maximum distance, or the average distance from all disturbed base stations as the distance from the candidate base station to the disturbed base station. In addition, the distance from the candidate base station to the disturbed base station can also be determined by weighted average or weighted maximum distance of the distances. Further, the server sorts the distances between each candidate base station and the disturbed base station in ascending or descending order to obtain a base station distance order table. According to the base station distance order table, the distance target base stations corresponding to the number of required base stations are determined from the candidate base stations, and the frequency range provided by the target base stations is configured as the spectrum resource. For example, the base station distance order table is arranged in descending order, the number of required base stations is N, and N is a positive integer. The first N candidate base stations are taken from the base station distance order table as the target base stations.

[0102] In this embodiment, the candidate base station far away from the interfered base station can significantly reduce the interference effect, thereby improving the link quality and signal-to-noise ratio and enhancing the reliability of uplink communication. The target base station is dynamically selected according to the distance index, the spectrum resource is allocated to the candidate station with less interference or controllable interference, and the spectrum utilization and system capacity are improved.

[0103] In an exemplary embodiment, step S204 determines the resource configuration strategy of the airborne device uplink of the air-to-ground broadband communication according to the second comparison result, including:

[0104] In the case where the second comparison result is the sum of the number of interfered base stations and the number of demand base stations, which is greater than or equal to the total number of base stations, all base stations except the interfered base stations are taken as target base stations, and the frequency range provided by the target base stations is taken as the spectrum resource configuration; and the transmit power is configured as the maximum transmit power threshold of the airborne device.

[0105] Optionally, in the case where the second comparison result is the sum of the number of interfered base stations and the number of demand base stations, which is greater than or equal to the total number of base stations, the number of base stations that cannot meet the service demand due to the spectrum resource provided by the current base station, or the spectrum resource provided by the current base station is not sufficient, the server takes all base stations except the interfered base stations as target base stations, and takes the frequency range provided by the target base stations as the spectrum resource configuration for the airborne device; in addition, because the frequency range provided by the target base stations may not meet the current service demand in this case, the transmit power is configured as the maximum transmit power threshold of the airborne device for frequency compensation.

[0106] In this embodiment, in the case where the spectrum resource is limited or the interference is serious, the available spectrum range is expanded to maintain the continuity and stability of the service as much as possible. Adjusting the transmit power of the airborne device to the maximum value helps to resist the signal attenuation caused by insufficient spectrum resource, improves the signal-to-noise ratio of the uplink, and enhances the robustness of the uplink.

[0107] In an exemplary embodiment, another airborne device uplink resource configuration method is provided, including:

[0108] Step 1: Obtain the maximum transmit power of the ATG system airborne terminal (airborne device) in the uplink as Pmax=40dBm (maximum transmit power threshold), and pre-store the table of the straight-line distance d between the ATG base station and the ATG airborne terminal and the corresponding maximum transmit power under the distance [dx, Px] (pre-constructed airborne transmit power configuration table). The uplink carrier of the ATG system is 20MHz, and the occupied frequency resource is 100RB (base station), i.e. RB0=100 (total number of base stations).

[0109] Step 2, at a certain time, the real-time traffic demand of the ATG system on-board passengers requires 70 RBs of frequency resources, so RB1=70 (the number of demand base stations). The ATG ground base station judges the interference strength of the interference signal from other services on the same frequency, the spectrum position of the interference signal, and the total spectrum resource occupied by the interference signal, and RB2=20 (the number of interfered base stations). At this time, it is judged that RB0 (100)> RB1 (70)+ RB2 (20), so 20 RBs of the 100 RB resources of the ATG uplink will be punctured, and the remaining 80 RBs of spectrum resources (candidate base stations) will be selected by the strategy of selecting 70 RBs (target base stations) far away from the interfered RBs for the ATG uplink. At this time, the uplink spectrum resource is sufficient, so the transmit power can be appropriately reduced to reduce the risk of interference. According to the real-time measurement of the straight-line distance d3 between the ATG base station and the ATG airborne terminal, the corresponding transmit power P3 is found as the real-time transmit power of the ATG airborne terminal at this time.

[0110] Step 3, at another time, the real-time traffic demand of the ATG system on-board passengers requires 90 RBs of frequency resources, so RB1=90. The ATG ground base station judges the interference strength of the interference signal from other services on the same frequency, the spectrum position of the interference signal, and the total spectrum resource occupied by the interference signal, and RB2=15. At this time, it is judged that RB0 (100)< RB1 (90)+ RB2 (15), so 15 RBs of the 100 RB resources of the ATG uplink will be punctured, and the remaining 85 RBs of spectrum resources do not meet the demand of the ATG uplink traffic. At this time, the uplink spectrum resource is insufficient, so the transmit power needs to be configured as the highest capability to make up for the link budget, and the real-time transmit power of the ATG airborne terminal at this time is configured as Pmax=40 dBm.

[0111] In the embodiment, the ATG system airborne equipment co-frequency multiplexed with the ground public network base station determines the required spectrum resource according to the real-time uplink traffic demand of the user on the plane, and adjusts the transmission power of the ATG airborne terminal through the uplink resource allocation situation, for ensuring the best user experience of the ATG system and the lowest inter-system interference. The common terminal uplink interference mitigation measure in the current mobile communication system is to adjust the transmission power to compensate for the path loss of terminals in different positions according to the estimated path loss and the gain of the transceiver antenna. The application introduces an ATG aircraft uplink resource allocation method, which can select the optimal uplink frequency resource according to the uplink traffic demand of the passenger cabin user on the aircraft and the uplink interference received by the ground base station, in order to ensure the optimal performance of the ATG system and the lowest inter-system interference risk, to ensure the link performance, and to reduce the interference strength between systems through real-time system link power control to ensure the coexistence of air-ground co-frequency systems.
