Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
In the fifth Generation cellular network technology (5 th-Generation, abbreviated as 5G), researchers develop a Massive antenna technology (Massive Multiple-Input Multiple-Output, abbreviated as Massive MIMO), which provides a Massive MIMO system that can control the phase and amplitude of signals transmitted or received by each Massive MIMO antenna unit, and adjust Multiple Massive MIMO antenna units to generate beams with directivity by Multiple Massive MIMO antenna units, so that wireless signal energy can form electromagnetic wave superposition at a target position, thereby improving the signal intensity at the target position. In the network coverage of high-rise buildings, 32T32R and 64T64R Massive MIMO antenna arrays are generally used, and the 32T32R and 64T64R Massive MIMO antenna arrays are subjected to beam forming in the horizontal direction and the vertical direction, so that the coverage of the 5G network to the high-rise buildings is effectively enhanced. However, in the prior art, after the Massive MIMO antenna is subjected to beam forming, network coverage is performed on high-rise buildings too much, and a network coverage mode most suitable for each high-rise building cannot be selected for different high-rise buildings, which causes a problem of poor coverage effect when a 5G network covers the high-rise buildings.
Based on the method and the device, the optimal network coverage mode is selected for the antenna according to the actual installation scene of the antenna and the high-rise building to be covered, and the antenna can completely cover the high-rise building by adopting the beam emitted after the optimal network coverage mode is adopted, so that the effect of the 5G network when the high-rise building is covered is improved, and the user experience degree is improved.
The method for network coverage between buildings is applied to terminal equipment, and the terminal equipment is used for a server for adjusting antenna parameters, or is computer equipment which is not used for laboratories, and the like. Fig. 1 is a schematic application diagram of the inter-building network coverage method provided by the present application. In the figure, network coverage modes of multiple antennas are stored in the terminal device, and after the terminal device acquires the position information and the height information of the first antenna and the target building, the terminal device determines the optimal network coverage mode, namely the target network coverage mode, in all the network coverage modes based on the position information and the height information of the first antenna and the target building. The first antenna can achieve the effect of complete coverage when the target building is subjected to network coverage by adopting the target network coverage mode. The first antenna is one of a plurality of antennas arranged on the base station, and the inter-building network coverage method provided by the application can output a target network coverage mode of the antenna required to be used on the base station, so that a beam emitted by the antenna for network coverage can enable a 5G network to fully cover a target building.
Referring to fig. 2, an embodiment of the present application provides a method for network coverage between buildings, including:
s201, acquiring a first height of a lowest point on a first antenna from the ground, a second height of a highest point on a target building from the ground, a first distance between the first antenna and the target building and a first width of the target building.
The first antenna refers to any one of the Massive MIMO antenna arrays, the lowest point of the first antenna can also be understood as the lowest mounting point of the first antenna on a base station, and the first height can also be understood as the height from the ground plane of the lowest mounting point. When the terminal device obtains the first distance between the first antenna and the target building, the longitude and latitude information of the first antenna and the longitude and latitude information of the target building are obtained first, and then the first distance between the first antenna and the target building is determined according to the longitude and latitude information of the first antenna and the longitude and latitude information of the target building. The latitude and longitude information of the first antenna and the latitude and longitude information of the target building can be directly acquired by a locator including a Global Positioning System (GPS) and then sent to the terminal device, or the latitude and longitude information of the first antenna and the latitude and longitude information of the target building can be directly input to the terminal device by a worker. The first width of the target building refers to a length of the target building in a horizontal direction. Optionally, the first height, the second height, the first distance and the first width are all values in meters, for example, the first height is 30 meters, the second height is 60 meters, the first distance is 1000 meters, and the first width is 90 meters.
And S202, determining the vertical lobe width of the first antenna according to the first height, the second height and the first distance.
The vertical lobe width of the first antenna defines the beam angle of the first antenna in the vertical plane. The purpose of determining the vertical lobe width of the first antenna based on the first height, the second height and the first distance is to allow the first antenna to cover exactly the entire target building at the second height when transmitting a beam at the calculated vertical beam angle of the first antenna. As shown in fig. 3, the first height is 20 meters, the second height is 50 meters, and the first distance is 170 meters, then the vertical lobe width of the first antenna determined according to the first height, the second height, and the first distance is the angle a shown in the figure.
And S203, determining the horizontal lobe width of the first antenna according to the first distance and the first width.
The horizontal lobe width of the first antenna defines the beam angle of the first antenna in the horizontal plane. The purpose of determining the horizontal lobe width of the first antenna based on the first distance and the first width is to allow the first antenna to cover exactly the target building of the first width when transmitting a beam at the calculated horizontal beam angle of the first antenna. As shown in fig. 4, if the first distance is 170 meters and the first width is 190 meters, the horizontal lobe width of the first antenna determined according to the first distance and the first width is the angle B shown in the figure.
And S204, determining a target network coverage mode of the first antenna corresponding to the target building from a plurality of network coverage modes according to the vertical lobe width of the first antenna and the horizontal lobe width of the first antenna, wherein each network coverage mode comprises the vertical lobe width and the horizontal lobe width of the corresponding antenna.
The terminal device stores a plurality of network coverage patterns, and after calculating the vertical lobe width of the first antenna and the horizontal lobe width of the first antenna based on step S202 and step S203, a target network coverage pattern corresponding to the vertical lobe width of the first antenna and the horizontal lobe width of the first antenna needs to be determined from the plurality of network coverage patterns. It can be understood that, in order to achieve the effect of full coverage of the target building, when determining the target network coverage mode, the vertical lobe width of the first antenna needs to be smaller than the vertical lobe width of the antenna corresponding to the target network coverage mode, and the horizontal lobe width of the first antenna needs to be smaller than the horizontal lobe width of the antenna corresponding to the target network coverage mode.
For example, there are 6 network coverage patterns shown in table 1, and assuming that the vertical lobe width of the first antenna calculated by step S202 is 16.72 ° and the horizontal lobe width of the first antenna is 58.39 °, since the vertical lobe width of the antenna and the horizontal lobe width of the antenna corresponding to the network coverage pattern 6 in table 1 are 25 ° and 65 °, respectively, which are the network coverage patterns closest to the vertical lobe width of the first antenna and the horizontal lobe width of the first antenna, the network coverage pattern 6 in table 1 is the target network coverage pattern of the first antenna.
| Network overlay mode numbering | Vertical lobe width/° | Horizontal lobe width/° |
| Network overlay mode 1 | 6 | 105 |
| Network overlay mode 2 | 6 | 65 |
| Network overlay mode 3 | 12 | 110 |
| Network overlay mode 4 | 12 | 65 |
| Network overlay mode 5 | 25 | 110 |
| Network overlay mode 6 | 25 | 65 |
TABLE 1
Optionally, a difference between the vertical lobe width of the first antenna and the vertical lobe width of the antenna corresponding to the target network coverage mode is smaller than or equal to a first preset difference, and a difference between the horizontal lobe width of the first antenna and the horizontal lobe width of the antenna corresponding to the target network coverage mode is smaller than or equal to a second preset difference. The first preset difference value and the second preset difference value can be set by a worker according to actual needs, and the application is not limited.
According to the method for network coverage among buildings provided by the embodiment, an optimal network coverage mode which can be adopted by the antenna, namely a target network coverage mode, can be output according to the actual installation scene of the antenna and the target high-rise building to be covered by the antenna, wherein the target network coverage mode comprises a target vertical lobe width and a target horizontal lobe width, and a worker can adjust the setting of the antenna based on the target vertical lobe width and the target horizontal lobe width, so that the purpose that the beam emitted by the antenna can fully cover the target high-rise building is achieved. Therefore, the inter-building network coverage method provided by the embodiment can improve the coverage effect when the 5G network covers the high-rise building, and improve the experience of the 5G user of the high-rise building.

S503, obtaining a first absolute value of a difference between the second height and the first height, and determining a third ratio of the first absolute value to the first distance.

And S505, determining the sum of the first angle and the second angle as the vertical lobe width of the first antenna.
I.e. the vertical lobe width of the first antenna theta = theta 1 +θ 2 . For example, if the first height is 20 meters, the second height is 50 meters, and the first distance is 170 meters, the vertical lobe width of the first antenna calculated through steps S701 to S705 is 16.71782 °.
Step S503 includes:
s506, a fourth ratio of the half value of the first width to the first distance is determined.

Step S506 to step S507 are to determine the horizontal lobe width of the first antenna, which is equal to twice the arctangent value of the fourth ratio, and is expressed by ρ = degees (ATAN (L1/2/D1)) × 2, where L1 is the first width, D1 is the first distance, ATAN is the arctangent function, and degees is represented by DEGREES, i.e., °.
As shown in fig. 5, when steps S501 to S507 are executed on the basis of the first embodiment, the lobe width calculation process represented by steps S501 to S507 is executed after the basic data acquisition process represented by step S201 in the first embodiment, and is executed before the mode determination process represented by step S204 in the first embodiment.
