Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides an addressing method for a base station deployment location, including the following steps:
s1: acquiring test data comprising signal strength information and corresponding geographical location information;
specifically, the method provided in the embodiment of the present invention may use an addressing device at a base station deployment location as an execution subject, where a mobile terminal may report measurement data periodically, and the addressing device may obtain the measurement data reported by the mobile terminal, where the measurement data includes a location where the mobile terminal is located and signal strength information received by the location, that is, reference signal received power. In addition, the measurement data can also be acquired in a drive test frequency sweep mode.
S2: according to the geographical position information, the signal intensity information is converged into a corresponding grid; the grid is obtained by dividing an area to be planned of the wireless network according to the geographical position;
specifically, a digital map of an area to be planned of the wireless network may be rasterized, and each grid may have a size of 50 meters × 50 meters. The obtained signal strength information may be filled in a grid corresponding to the geographical location according to the measurement data obtained in step S1. I.e. each grid may comprise a plurality of sample points of signal strength information.
S3: determining the position of the weak coverage grid according to the signal strength information corresponding to each grid;
specifically, based on the signal strength information of the plurality of sampling points in each grid, it can be determined whether the grid is a weak coverage grid. For example, when the average value of the signal strength information of the plurality of sampling points in the grid is smaller than the low level threshold, the grid is determined to be a weak coverage grid. It should be noted that the weak coverage grid means that the base stations are too far apart, or the boundary area is poor in signal due to building obstruction. The weak coverage is typically less than-90 dBm at Rxlev (received signal level). The grid of weak coverage directly affects call quality.
S4: and according to the position of each weak coverage grid, taking a plurality of weak coverage grids as the signal coverage area of the same base station to be deployed to form the deployment areas of a plurality of base stations to be deployed.
Specifically, for each grid in the area to be planned of the wireless network, each grid may be filtered first to remove the grid with obviously wrong measurement data, and according to the position of each weak coverage grid obtained in step S3, a plurality of weak coverage grids with a short distance may be merged to serve as the signal coverage area of the same base station to be deployed, so as to form a plurality of base station deployment areas, each base station deployment area is deployed with one base station, and the signal coverage area of the base station includes a plurality of weak coverage grids with a short distance. According to the radius (such as 200 meters) of the coverage area of the base station signals, weak coverage grids within a range of 200 meters apart can be combined, and the same base station to be deployed provides signals. The position of a weak coverage grid which can be provided by the same base station to be deployed can be determined through a density-like algorithm, then an envelope cluster containing the weak coverage grid is output through convex hull stacking, the base station to be deployed can be located in the envelope cluster, and the envelope cluster is located in the signal coverage area of the base station to be deployed. As shown in fig. 2, a gray grid 1 represents a weak coverage grid, a first area 3 represents that a short distance weak coverage grid is merged, and a second area 1 represents that a plurality of weak coverage grids form an envelope cluster.
According to the addressing method for the deployment position of the base station, provided by the embodiment of the invention, through acquiring the measurement data and rasterizing the area to be planned, the network problem of the grid can be determined according to the signal intensity information of each grid, so that a plurality of weak coverage grids can be combined to provide signals by the same base station, and the proper position of the base station to be deployed is determined according to the position of the weak coverage grid.
In order to simplify the complex site survey work, on the basis of the foregoing embodiment, as shown in fig. 3, the method for addressing the deployment location of the base station according to the embodiment of the present invention may further include:
step S5: and deploying the base station corresponding to the scene information in the deployment area according to the scene information of the deployment area of the base station to be deployed.
Specifically, the scene information of the deployment area of the base station may be determined in combination with the digital map, for example, the scene information may be indoor, outdoor or road, and for the deployment areas of different scene information, different types of base stations may be deployed. The scene information is an indoor deployment area, and an indoor distribution system can be deployed in the deployment area. For a deployment area with outdoor scene information, whether macro stations exist or not can be searched within 250 meters around the deployment area, and if so, base stations with signal coverage ranges between the macro stations and indoor stations can be built in the center or the periphery of the deployment area. Conversely, if not, the macro station is deployed within the deployment area according to the area of the deployment area, the coverage of the macro station, the overlapping coverage, and the like. Of course, if the scene information is a road, a base station having a signal coverage ranging between the macro station and the indoor station may be constructed in the center or the periphery of the deployment area.
On the basis of the foregoing embodiment, step S3 determines the position of the weak coverage grid according to the signal strength information corresponding to each grid, including:
according to the signal intensity information corresponding to each grid, determining the sampling times that the signal intensity acquired in the current grid is smaller than a first preset value;
and if the proportion of the sampling times to the total sampling times in the current grid is greater than a second preset value, determining that the current grid is a weak coverage grid.
Specifically, according to the signal strength information corresponding to the plurality of sampling points in each grid, it may be counted that the signal strength value acquired in each grid is less than the sampling frequency of a first preset value (e.g., -90dBm), and if the ratio of the sampling frequency of the signal strength value in a certain grid less than the first preset value to the total sampling frequency in the grid is greater than the first preset value (e.g., 20%), it may be determined that the grid is a weak coverage grid.
On the basis of the foregoing embodiment, step S4 specifically includes:
calculating the number of the weak coverage grids in a first preset range of each grid according to the positions of the weak coverage grids;
and if the number of the weak coverage grids is greater than a third preset value, determining that the current grid is a core grid.
Specifically, each grid G (i, j) is traversed, all weakly covered grids are labeled 1, others are labeled 0, and for distinction, each grid is labeled G (i, j)0The example is illustrated with a grid size of 50 meters × 50 meters and a base station coverage area radius of 200 meters0Within 200 meters (first predetermined range) of the core grid operation matrix
The matrix A comprises 81 elements and is provided with a standard vector S0＝(1,1,1,1,1,1,1,1,1)TThen, if the binary value A (i, j) × S0>40, i.e. the current grid G (i, j)0Is greater than 40 (third predetermined value), grid G (i, j)0Is a core grid. All core grids are labeled 1 and the other grids are labeled 0, each grid being labeled G (i, j) for differentiation1And (4) showing.
Further, step S4 specifically includes:
for each core grid, if the number of the core grids in the second preset range of the current core grid is greater than the fourth preset value, determining the position of the grid to be added according to the position of the current core grid and the number of the core grids in the corresponding second preset range.
In particular, each grid G (i, j) is traversed1If the grid G (i, j)1Is a core grid marked as 1, and constructs a grid position operation matrix of the station adding
The matrix B comprises 25 elements and is provided with a standard vector S1＝(1,1,1,1,1)TThen, if the binary value B (i, j) × S1>1, that is, the number of core grids within 100 meters of the current core grid (second preset range) is greater than 1 (fourth preset value), then
i + 3-log { (binary [ B (i, j) × S)1])/2}
j' ═ j + 3-log { (binary [ B (i, j)T*S1])/2}
G (i ', j') is used as the position of the grid of stations to be added. All grids to be added are marked with 1 and others with 0, each grid being used for G (i, j) for differentiation2And (4) showing.
Further, step S4 specifically includes:
and for each grid of the stations to be added, if the number of the grids of the stations to be added in the third preset range of the grid of the current stations to be added is greater than the fifth preset value, the position of the grid of the current stations to be added is the position of the base station deployment.
In particular, each grid G (i, j) is traversed2If the grid is G (i, j)2Is a grid marked as 1 for the station to be added, and constructs a base station deployment position operation matrix
The matrix C comprises 25 elements and is provided with a standard vector S2＝(1,1,1,1,1)TThen, if the binary value C (i, j) × S2>1, that is, the number of grids to be added within a range of 100 meters of the grid to be added currently (third preset range) is greater than 1 (fifth preset value), the position of the grid to be added currently is the base station deployment position, as shown in fig. 4, and the black grid is the base station deployment position. And the grids of all the base station deployment positions can be marked as 1, and other grids can be marked as 0, so that the quick determination of the base station deployment positions can be realized.
In summary, the technical scheme provided by the embodiment of the invention firstly realizes accurate discovery of the weak coverage area and solves the problem of weak coverage omission possibly existing in the prior complaint information collection, drive test frequency sweep and other modes. And the corresponding base stations are deployed according to the scene information, so that the complex site survey work is greatly simplified.

Compared with the traditional site planning method, the efficiency of site survey planning is greatly improved, the skill requirement of optimization personnel is reduced, and the resource investment in the aspects of manpower and material resources is saved.
