[0060] Currently, with the rapid development of 5G networks, the requirements for network coverage, capacity and performance are becoming increasingly higher.

[0061] In related technologies, by adjusting the configuration and parameters of antenna beams, precise coverage of specific areas can be achieved, network resource utilization can be improved, interference can be reduced, and overall network performance can be improved. However, in actual applications, it is found that the dynamic beam adjustment function of 5G base stations is subject to many restrictions, and the current beam scenario parameter configuration mainly relies on manual planning.

[0062] In view of this, an antenna beam scene parameter adjustment method, device, electronic device and storage medium are provided in the embodiments of the present application. By analyzing the reported data of the terminals in the target area, the optimal beam coverage scenario of the current antenna is determined, and then a beam scene parameter adjustment strategy is generated. The beam scene parameters of the antenna can be automatically adjusted to improve the accuracy and efficiency of the base station signal coverage, effectively meeting the user's usage needs.

[0063] The specific implementation of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings. First, an antenna beam scene parameter adjustment method provided in the embodiment of the present application is described in conjunction with the accompanying drawings.

[0064] Please refer to Figure 1 , Figure 1 The schematic diagram of the implementation environment of an antenna beam scene parameter adjustment method provided by an embodiment of the present application is shown. In the implementation environment, the main software and hardware entities involved include a terminal processor 110 and a server 120.

[0065] Specifically, the terminal processor 110 may be installed with a related antenna beam scene parameter adjustment method control program, and the server 120 is a background server of the control program. The terminal processor 110 and the background server 120 are connected in communication. The antenna beam scene parameter adjustment method provided in the embodiment of the present application may be executed on the terminal processor 110 side.

[0066] Server 120 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0067] In addition, the server 120 may also be a node server in the blockchain network.

[0068] The terminal processor 110 and the server 120 may establish a communication connection through a wireless network. The wireless network uses standard communication technology and / or protocols, and the network may be set to the Internet, or any other network, such as but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, or any combination of a wireless network, a private network, or a virtual private network. Moreover, the above-mentioned software and hardware entities may use the same communication connection mode or different communication connection modes, and this application does not impose any specific restrictions on this.

[0069] Of course, it is understandable that Figure 1 The implementation environment in the embodiment of the present application is only some optional application scenarios of the antenna beam scene parameter adjustment method provided in the embodiment of the present application, and the actual application is not fixed. Figure 1 The software and hardware environment shown is not specifically limited in this application.

[0070] like Figure 2 As shown, Figure 2 It is a flowchart of an antenna beam scene parameter adjustment method provided in an embodiment of the present application, which specifically includes but is not limited to steps S100 to S400.

[0071] Step S100: Acquire reported data of all terminals in the target area.

[0072] In the embodiment of the present application, the target area can be any residential area, any business district, or any square, and the reported data of all terminals in the target area are received through the 5G base station. The terminal can be a mobile device such as a smart phone.

[0073] Furthermore, the reported data of the terminal includes MR (Measurement Report, MR) data. MR data refers to the measurement report generated when the user uses a mobile device to make a call, which records the user's cell location information, mobile phone transmission power, cell network quality and other information.

[0074] Specifically, as an optional implementation manner, the acquiring the reported data of all terminals in the target area includes:

[0075] Obtaining a reference signal received power of each terminal in the target area;

[0076] The terminals whose reference signal received power is greater than or equal to the third threshold are screened and determined as valid terminals, and then the reported data of all the valid terminals are used as valid reported data.

[0077] In an embodiment of the present application, the reference signal received power (RSRP) value in the reported data of the terminal is read, and the terminal whose reference signal received power is greater than or equal to the third threshold is screened and determined as a valid terminal. It is understandable that the present application does not limit the specific value of the third threshold, and it can be flexibly selected according to actual needs. Exemplarily, the third threshold can be selected as -110dBm, then all terminals with reference signal received power greater than -110dBm in the target area are regarded as valid terminals, and the reported data of all valid terminals are regarded as valid reported data, while the reported data of the remaining terminals may be data in weak signal or invalid areas, which may become noise data interference analysis results.

[0078] Step S200: Determine the beam coverage parameters of the antenna according to the reported data; wherein the beam coverage parameters include horizontal beam width, vertical beam width and beam coverage height.

[0079] In the embodiment of the present application, it can be understood that the reporting data sent by the terminal to the base station contains different types of data fields, and the key fields of the entire data packet can be queried to obtain the required data for determining the beam coverage parameters of the 5G base station antenna.

[0080] Among them, the beam coverage parameters include horizontal beam width, vertical beam width and beam coverage height. The horizontal beam width refers to the angle in the direction of the main beam of the antenna when the radiation power on both sides of the direction of maximum antenna transmission power is halved. This parameter reflects the coverage range of the antenna in the horizontal direction; the vertical beam width refers to the angle in the vertical direction of the antenna when the radiation power on both sides of the direction of maximum antenna transmission power is halved. This parameter reflects the coverage range of the antenna in the vertical direction; the beam coverage height refers to the absolute height of the terminal covered by the antenna signal, which is crucial to ensuring signal coverage in high-rise buildings or areas with complex terrain.

[0081] Specifically, as an optional implementation, please refer to Figure 3 , Figure 3 It is a schematic diagram of a process for determining antenna beam scene parameters provided in an embodiment of the present application, wherein determining the beam coverage parameters of the antenna according to the reported data includes:

[0082] Step S210: determining the horizontal angle of arrival, vertical angle of arrival and timing advance of each terminal according to the reported data;

[0083] Step S220: determining the horizontal beam width of the antenna based on the horizontal arrival angle of each terminal;

[0084] Step S230: determining the vertical beam width of the antenna based on the vertical angle of arrival of each terminal;

[0085] Step S240: Determine the beam coverage height of the antenna based on the timing advance of each terminal.

[0086] In an embodiment of the present application, after the reported data of all terminals in the target area are obtained, a key field search query is performed on the reported data of each terminal to determine the horizontal arrival angle, vertical arrival angle and time advance of each terminal.

[0087] Furthermore, the horizontal beam width of the antenna is determined according to the horizontal angle of arrival (HAOA) of each terminal, the vertical beam width of the antenna is determined according to the vertical angle of arrival (VAOA) of each terminal, and the beam coverage height of the antenna is determined according to the timing advance (TA) of each terminal.

[0088] Specifically, as an optional implementation, please refer to Figure 4 , Figure 4 is a schematic diagram of a process for determining a horizontal beam width provided by an embodiment of the present application, wherein determining the horizontal beam width of the antenna based on the horizontal angle of arrival of each terminal includes:

[0089] determining an antenna normal of the antenna;

[0090] Determine a first terminal and a second terminal on both sides of the antenna normal line in the horizontal direction; wherein a difference between the radiation power at the first terminal and the radiation power of the antenna normal line and a difference between the radiation power at the second terminal and the radiation power of the antenna normal line both meet a first threshold;

[0091] The horizontal beam width of the antenna is determined according to a horizontal arrival angle of the first terminal and a horizontal arrival angle of the second terminal.

[0092] In the embodiment of the present application, since the horizontal beam width refers to the angle between the two directions where the radiation power drops by 3dB on both sides of the direction of maximum radiation power of the antenna in the horizontal direction, it is necessary to first confirm the sky normal to determine the direction in which the antenna radiation power is maximum.

[0093] For example, please refer to Figure 5 , Figure 5It is a schematic diagram of determining the horizontal beam width according to the horizontal angle of arrival provided by an embodiment of the present application. In the top view of the 5G base station, the direction of the antenna normal can be determined, and further, the first terminal and the second terminal on both sides of the antenna normal in the horizontal direction are determined, wherein the difference between the radiated power at the first terminal and the radiated power of the antenna normal and the difference between the radiated power at the second terminal and the radiated power of the antenna normal both meet the first threshold. It can be understood that the present application does not limit the specific value of the first threshold, and it can be flexibly selected according to actual needs. Exemplarily, the first threshold can be taken as 3dB, that is, when the maximum radiated power at the antenna normal is MdB, the radiated power of each terminal in the target area can be traversed, and the terminals with a radiated power of M-3dB on each side in the horizontal direction are determined as the first terminal and the second terminal.

[0094] Furthermore, since the horizontal beam width refers to the angle between the two directions where the radiation power of the antenna decreases by 3 dB on both sides of the direction of maximum radiation power of the antenna in the horizontal direction, the angle between the antenna normal and the first terminal (for example Figure 5 α1 in ) plus the angle between the antenna normal and the second terminal (e.g. Figure 5 The horizontal beam width can be obtained by using α2 in the figure.

[0095] It can be understood that the angle between the antenna normal and the first terminal (eg Figure 5 The α1 in (a) can be calculated from the horizontal arrival angle of the first terminal, and the angle between the antenna normal and the second terminal (e.g. Figure 5 α2) in can be calculated from the horizontal arrival angle of the second terminal.

[0096] It should be noted that since base stations from different manufacturers define the numerical range of the horizontal angle of arrival differently, for example, taking the antenna normal as the starting position, each 0.5 degree is a unit, and the counterclockwise direction is positive, the HAOA value can range from 0 to 719, a total of 720 integers, corresponding to a 360-degree counterclockwise rotation from the antenna normal as the starting point. That is to say, when the HAOA in the reported data is parsed to be 0, it represents that the actual angle between the terminal and the antenna normal is [0°, 0.5°); when the HAOA in the reported data is parsed to be 1, it represents that the actual angle between the terminal and the antenna normal is [0.5°, 1°).

[0097] In practical applications, HAOA can also be quickly calculated as the actual angle using the following formula:

[0098]

[0099] Wherein, α is the actual angle between the terminal and the antenna normal, and HAOA is the HAOA value in the reported data.

[0100] Of course, it can be understood that the above optional implementation method of calculating the actual angle size is only used for illustrative purposes and does not mean to limit the actual implementation method of obtaining the actual angle size. It can be selected independently according to the actual usage scenario.

[0101] Further, when the included angle between the antenna normal and the first terminal is calculated (for example Figure 5 The size of α1 in α1) is related to the angle between the antenna normal and the second terminal (e.g. Figure 5 After determining the size of α2) in , the two can be added together to obtain the horizontal beam width of the antenna.

[0102] Specifically, as an optional implementation, please refer to Figure 6 , Figure 6 is a schematic diagram of a process for determining a vertical beam width provided by an embodiment of the present application, wherein the vertical beam width of the antenna is determined based on the vertical angle of arrival of each terminal, including:

[0103] determining an antenna normal of the antenna;

[0104] Determine a third terminal and a fourth terminal on both sides of the antenna normal line in the vertical direction; wherein a difference between the radiation power at the third terminal and the radiation power of the antenna normal line and a difference between the radiation power at the fourth terminal and the radiation power of the antenna normal line both meet a second threshold;

[0105] The vertical beam width of the antenna is determined according to the vertical angle of arrival of the third terminal and the vertical angle of arrival of the fourth terminal.

[0106] In the embodiment of the present application, since the vertical beam width refers to the angle between the two directions where the radiation power drops by 3dB on both sides of the direction of maximum radiation power of the antenna in the vertical direction, it is necessary to first confirm the sky normal to determine the direction in which the antenna radiation power is maximum.

[0107] For example, please refer to Figure 7 , Figure 7It is a schematic diagram of determining the vertical beam width according to the vertical angle of arrival provided by an embodiment of the present application. In the longitudinal section of the 5G base station, the direction of the antenna normal can be determined, and further, the third terminal and the fourth terminal on both sides of the antenna normal in the vertical direction are determined, wherein the difference between the radiated power at the third terminal and the radiated power of the antenna normal and the difference between the radiated power at the fourth terminal and the radiated power of the antenna normal both meet the second threshold. It can be understood that the present application does not limit the specific value of the second threshold, and it can be flexibly selected according to actual needs. Exemplarily, the second threshold can be taken as 3dB, that is, when the maximum radiated power at the antenna normal is NdB, the radiated power of each terminal in the target area can be traversed, and the terminals with a radiated power of N-3dB on each side in the vertical direction are determined as the third terminal and the fourth terminal.

[0108] Furthermore, since the vertical beam width refers to the angle between the two directions where the radiation power drops by 3 dB on both sides of the direction of maximum radiation power of the antenna in the vertical direction, the angle between the antenna normal and the third terminal (for example Figure 7 β1 in ) plus the angle between the antenna normal and the fourth terminal (e.g. Figure 7 The vertical beam width can be obtained by using β2 in the figure.

[0109] It can be understood that the angle between the antenna normal and the third terminal (eg Figure 7 The β1 in ( ) can be calculated from the vertical arrival angle of the third terminal, and the angle between the antenna normal and the fourth terminal (e.g. Figure 7 β2) in can be calculated from the vertical arrival angle of the fourth terminal.

[0110] It should be noted that since base stations from different manufacturers define the numerical range of the vertical angle of arrival differently, for example, taking the antenna normal as the starting position, 1 degree as a unit, and the clockwise direction as positive, the VAOA value can range from 0 to 359, a total of 360 integers, corresponding to a 360-degree clockwise rotation from the antenna normal as the starting point. That is to say, when the VAOA in the reported data is parsed to be 0, it represents that the actual angle between the terminal and the antenna normal is [0°, 1°); when the VAOA in the reported data is parsed to be 1, it represents that the actual angle between the terminal and the antenna normal is [1°, 2°).

[0111] In practical applications, VAOA can also be quickly calculated as the actual angle using the following formula:

[0112]

[0113] Wherein, β is the actual angle between the terminal and the normal line of the longitudinal section antenna, and VAOA is the VAOA value in the reported data of the terminal.

[0114] Of course, it can be understood that the above optional implementation method of calculating the actual angle size is only used for illustrative purposes and does not mean to limit the actual implementation method of obtaining the actual angle size. It can be selected independently according to the actual usage scenario.

[0115] Further, when the included angle between the antenna normal and the third terminal is calculated (for example Figure 7 The size of β1 in β1) is related to the angle between the antenna normal and the fourth terminal (e.g. Figure 7 After determining the size of β2 in , the two can be added together to obtain the vertical beam width of the antenna.

[0116] Specifically, as an optional implementation, please refer to Figure 8 , Figure 8 This is a schematic diagram of a process for determining a beam coverage height provided by an embodiment of the present application, wherein determining the beam coverage height of the antenna based on the timing advance of each terminal includes:

[0117] Based on the timing advance of each terminal, calculate the relative height between each terminal and the antenna;

[0118] Determining the absolute height of each terminal based on the antenna feed height of the antenna and the relative height between each terminal and the antenna;

[0119] The average value of the absolute heights of all terminals is calculated to obtain the beam coverage height of the antenna.

[0120] In an embodiment of the present application, in a 5G base station network, each unit of TA corresponds to 39 meters in the actual distance. Therefore, by reading the value of the TA field in the reported data of each terminal, the distance between each terminal and the antenna feed can be calculated.

[0121] Specifically, as an optional implementation manner, the calculating, based on the timing advance of each terminal, a relative height between each terminal and the antenna includes:

[0122] Based on the timing advance of each terminal, calculate the distance between each terminal and the antenna feed of the antenna;

[0123] According to the vertical arrival angle of each terminal and the antenna tilt angle of the antenna, the relative height of each terminal and the antenna is obtained by calculating the distance between each terminal and the antenna feed of the antenna.

[0124] For example, please refer to Fig. 9 , Fig. 9It is a schematic diagram of determining the beam coverage height according to the time advance amount provided in an embodiment of the present application. By reading the TA values ​​of the third terminal and the fourth terminal, the distance between the third terminal and the antenna feed and the distance between the fourth terminal and the antenna feed can be calculated.

[0125] Furthermore, according to the vertical arrival angle of each terminal and the antenna tilt angle of the antenna, combined with the distance between each terminal and the antenna feeder of the antenna, the relative height of each terminal and the antenna can be calculated using the trigonometric cosine function.

[0126] For example, Fig. 9 As shown, the angle β1 between the third terminal and the antenna normal is calculated according to the VAOA of the third terminal, β1 is added to the antenna tilt angle, and the relative height between the third terminal and the antenna feed can be calculated using the trigonometric cosine function.

[0127] It is understandable that the angle β2 between the fourth terminal and the antenna normal can also be calculated based on the VAOA of the fourth terminal, β2 is subtracted from the antenna tilt angle, and the relative height between the fourth terminal and the antenna feed can be calculated using the trigonometric cosine function.

[0128] In practical applications, the relative height between any terminal and the antenna feed can also be quickly calculated using the following formula:

[0129]

[0130] Among them, h is the relative height between any terminal and the antenna feed; TA is the time advance of the terminal; β is the actual angle between any terminal and the normal line of the longitudinal section antenna; tilt is the antenna tilt angle; VAOA is the VAOA value in the reported data of any terminal.

[0131] Furthermore, by acquiring the antenna feed height and performing a difference operation between the relative height between each terminal and the antenna and the antenna feed height, the absolute height of each terminal relative to the horizon can be calculated and determined.

[0132] In actual application, after calculating the absolute heights of all terminals in the target area, the absolute heights of all terminals in the target area can be averaged to calculate the antenna beam coverage height.

[0133] Step S300: Determine the optimal beam coverage scenario of the antenna according to the beam coverage parameters.

[0134] In an embodiment of the present application, after the beam coverage parameters of the 5G base station antenna are obtained, the RPA (Robotic Process Automation) system can query the current optimal beam coverage scenario of the antenna based on the horizontal beam width, vertical beam width and beam coverage height matching of the antenna.

[0135] Exemplarily, the beam coverage scenario can be defined by the antenna equipment manufacturer according to the equipment parameters. Please refer to the following Table 1. Table 1 is a beam coverage scenario parameter table. There are 16 different applicable scenarios and correspondingly, there are 16 different parameter groups. The beam adjustment function of the existing 5G base stations is subject to many restrictions and is often manually planned by operators. The present application can directly match the acquired antenna beam coverage parameters with the defined beam coverage scenario parameter table to determine the optimal beam coverage scenario.

[0136] Table 1 Beam coverage scenario parameters

[0137]

[0138] In practical applications, you can further establish an evaluation interval. You can refer to the following Table 2. Table 2 is an evaluation interval table. By establishing an evaluation interval table and presetting the optimal beam coverage scenarios corresponding to different interval combinations, the RPA system can quickly calculate and match the optimal beam coverage scenarios for different target areas after obtaining the beam coverage parameters of different target areas.

[0141] Exemplarily, the following Table 3 is the interval matching table in the RPA system processing process, and Table 4 is the scene matching table in the RPA system processing process. That is to say, the RPA system can simultaneously process the antenna beam scene parameter adjustment tasks of multiple target areas within the service range of the 5G base station. By obtaining the reported data of the terminals in different target areas, the antenna beam coverage parameters can be calculated, which serves as the basis for subsequent interval matching and scene matching.

[0142] Of course, it can be understood that the above-mentioned optional implementation methods for determining the optimal beam coverage scenario of the antenna are only used for illustrative purposes and are not meant to limit the actual implementation methods for determining the optimal beam coverage scenario of the antenna, which can be independently defined according to the actual usage scenario.

[0147] Step S400: Determine the beam scene parameter adjustment strategy of the antenna according to the optimal beam coverage scenario, and then execute the beam scene parameter adjustment strategy.

[0148] In an embodiment of the present application, after the optimal beam coverage scenario of the antenna is determined, the corresponding beam scene parameter group information can be read, and based on the expected beam scene parameters and the currently set beam scene parameters, the antenna's beam scene parameter adjustment strategy can be determined and executed.

[0149] Exemplarily, beamforming technology can be used to adjust the phase and amplitude of each element in the antenna array to form a beam with specific directivity and gain, thereby optimizing the transmission and reception of signals. Therefore, when the beam scene parameter adjustment strategy is determined, the working parameters of each element in the antenna array can be adjusted according to the adjustment strategy to meet different geographical environments and application scenarios. In addition, during the entire antenna beam scene parameter adjustment process, no manual interaction is required, and the beam scene parameters of the antenna can be automatically adjusted to enable the current antenna to operate in the optimal beam coverage scenario, thereby improving the accuracy and efficiency of base station signal coverage and effectively meeting user needs.

[0150] Specifically, as an optional implementation, after determining the beam scene parameter adjustment strategy of the antenna according to the optimal beam coverage scenario, and then executing the beam scene parameter adjustment strategy, the method further includes:

[0151] After a first preset time interval, obtaining terminal coverage in the target area;

[0152] Based on the terminal coverage and the original coverage, the improvement effect of the beam scene parameter adjustment strategy is determined.

[0153] In an embodiment of the present application, after the beam scene parameter adjustment strategy of the antenna is determined and the beam scene parameter adjustment strategy is executed to adjust the beam scene parameters of the antenna, after a first preset time interval, the terminal coverage in the target area is obtained again, and compared with the original coverage before the beam scene parameters of the antenna are adjusted to determine the improvement effect of the beam scene parameter adjustment strategy, so as to facilitate subsequent confirmation of whether it is necessary to re-evaluate and optimize the beam scene parameters of the antenna in the target area.

[0154] In practical applications, the proportion of terminals with reference signal received power greater than -110 dBm and the proportion of signal-to-noise ratio greater than 3 dB may also be selected as improvement effect evaluation indicators.

[0155] Next, in conjunction with a specific application implementation process, the antenna beam scene parameter adjustment method provided in the present invention is described and explained in detail:

[0156] In an embodiment of the present application, a method for adjusting antenna beam scene parameters is provided. The method can be applied to base station antenna adjustment scenarios in wireless communications. By analyzing the reported data of terminals in the target area, the optimal beam coverage scenario of the current antenna is determined, and then a beam scene parameter adjustment strategy is generated. The method can automatically adjust the antenna beam scene parameters, improve the accuracy and efficiency of base station signal coverage, and effectively meet the user's usage needs.

[0157] Specifically, after starting to execute the antenna beam scene parameter adjustment task, the reporting data of all terminals in the target area can be obtained, and the terminals with terminal reference signal receiving power greater than -110dbm are regarded as valid terminals, and then the reporting data of the valid terminals are regarded as valid reporting data.

[0158] Furthermore, the horizontal arrival angle, vertical arrival angle and time advance of each terminal are extracted from the valid reported data according to the key fields, so as to determine the horizontal beam width of the antenna according to the horizontal arrival angle of each terminal, determine the vertical beam width of the antenna according to the vertical arrival angle of each terminal, and determine the beam coverage height of the antenna according to the time advance of each terminal.

[0159] Furthermore, after determining the beam coverage parameters of the antenna, the RPA system can evaluate and match the beam coverage parameters, determine the corresponding interval, and determine the optimal beam coverage scenario of the current antenna based on the connection relationship between the interval and the beam coverage scenario, and read the beam scenario parameters pre-defined by the equipment manufacturer.

[0160] Furthermore, based on the determined optimal beam coverage scenario and the corresponding beam scenario parameters, a beam scenario parameter adjustment strategy for the antenna is determined, and then the beam scenario parameter adjustment strategy is executed.

[0161] Finally, after adjusting the beam scene parameters of the antenna, the terminal coverage in the target area can be re-obtained after the first preset sampling interval, and the terminal coverage is compared with the original coverage before adjustment to determine the improvement effect of this beam scene parameter adjustment strategy.
