Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
With the rapid development of 5G, various operators are accelerating the construction of 5G networks. Since a large number of base stations need to be built in the 5G network, accurate 5G base station site planning is urgently needed. When planning the site of the 5G base station, the coverage condition of the 5G network is an extremely important planning basis when planning the site of the 5G base station.
In the prior art, a 5G network coverage condition is obtained by combining road testing and network simulation, and high-precision map data and road side data of a whole network are required to correct simulation data when the method is adopted. For example, in the invention patent with publication number CN102752790B, a road testing method and a coverage simulation method are effectively combined, in a grid where measurement points fall, a wireless network parameter measurement result obtained by the road testing method is used to replace a part of wireless network parameter simulation values obtained by the coverage simulation method, and the wireless network coverage of the network coverage evaluation area is determined by using the replaced wireless network parameter simulation values and the wireless network parameter simulation values that are not replaced.
However, when the above method is adopted, the cost of the high-precision map is high, and some remote areas and underdeveloped areas may not have the high-precision map, and the cost is high because the investment of manpower and material resources for obtaining the road test data of the whole network is large. In addition, because the thickness and material difference of the building wall are large, the loss difference of different walls cannot be accurately predicted, so that the accuracy of the indoor and outdoor wireless network parameter measurement results is low, and the accuracy of the network coverage detection state is influenced.
Therefore, in the embodiment of the invention, the coverage levels of a plurality of different first frequency bands of the first communication system are obtained, the coverage level of the second frequency band of the second communication system is obtained according to the coverage levels of the plurality of different first frequency bands, and then the coverage condition of the network of the second communication system in the target area is obtained according to the coverage level of the second frequency band.
Next, the network coverage status detection method provided by the embodiment of the present invention is described in detail through several specific embodiments.
Fig. 1 is a flowchart of a first embodiment of a network coverage status detection method provided in the present invention. An implementation subject of the network coverage status detection method provided in this embodiment may be a network coverage status detection device, where the network coverage status detection device may be implemented in any software and/or hardware manner, and for example, the network coverage status detection device may be a base station of a first communication system.
As shown in fig. 1, the method of this embodiment may include:
s101, obtaining the coverage level of a plurality of different first frequency bands corresponding to each grid in the target area.
The target area is a network coverage condition detection area, and the target area is a rasterized target area. The first frequency band is a frequency band of a first communication system. The coverage level is used for representing the signal strength of the communication network, and the coverage level of the first frequency band represents the signal strength of the first communication system network in the first frequency band.
Firstly, a base station of a first communication system acquires Measurement Report (MR) information reported by a terminal in a target area, wherein the MR information is one of important bases for evaluating network evaluation and optimization. The MR information may include an identifier of a serving base station, an identifier of a cell, frequency band information (i.e., frequency of the first frequency band), a coverage level of the cell in the first frequency band, and the like; then, determining MR information corresponding to each grid in the target area according to the MR information respectively reported by a plurality of terminals located in the target area and the longitude and latitude information corresponding to each grid included in the target area; then, according to the MR information corresponding to each grid, the coverage levels corresponding to a plurality of different first frequency bands corresponding to the grid are determined.
In practical application, one grid may correspond to a plurality of MR information, and the base station of the first communication system may determine the grid corresponding to the MR information reported by the terminal according to the location information of the terminal and the longitude and latitude information corresponding to each grid in the target area.
Exemplarily, determining the coverage levels respectively corresponding to the plurality of different first frequency bands corresponding to each grid according to the MR information corresponding to the grid may be implemented by:
specifically, for each first frequency band, performing average weighting processing according to the number of MR information corresponding to the first frequency band in the grid and the coverage level of the cell included in the MR information in the first frequency band, and determining the coverage level corresponding to the first frequency band in the grid.
Referring to fig. 2, if one grid corresponds to one cell for the first frequency band, average weighting processing is performed according to an average value of the coverage levels of the first frequency band included in all MR information in the one cell, and the coverage level corresponding to the first frequency band in the grid is determined.
If one grid corresponds to a plurality of cells aiming at the first frequency band, carrying out average weighting processing according to the average value of the coverage levels of the first frequency band included in all the MR information in each cell of the plurality of cells, and determining the coverage level corresponding to the first frequency band in the grid. Exemplarily, referring to fig. 3, one grid a corresponds to 3 cells, which are a cell 1a, a cell 1b, and a cell 1c, respectively, and then, an average weighting process is performed according to an average value of the coverage levels of the first frequency band included in all MR information in the cell 1a, an average value of the coverage levels of the first frequency band included in all MR information in the cell 1b, and an average value of the coverage levels of the first frequency band included in all MR information in the cell 1c, so as to determine the coverage level corresponding to the first frequency band in the grid.
It should be noted that fig. 3 only illustrates a case where one grid corresponds to a plurality of cells, and in practical applications, the number of cells corresponding to one grid may be determined according to actual base station conditions.
In addition, when the average weighting processing is performed, the weighting coefficient of the average value of the coverage levels of the first frequency band included in all the MR information in each cell is the ratio of the number of MR information of the cell in the grid to the total number of MR information of all the cells in the grid.
In order to make the present solution clearer, how to determine the coverage levels respectively corresponding to the plurality of different first frequency bands corresponding to each grid according to the MR information corresponding to the grid is described by a formula here:
coverage level corresponding to the first frequency band corresponding to the grid a = (number of MR information in the cell A1 = + average of coverage level of the first frequency band corresponding to the cell A1 + number of MR information in the cell A2 ± + average of coverage level of the first frequency band corresponding to the cell A2 + \ 8230, + number of MR information in the cell An × + average of coverage level of the first frequency band corresponding to the cell An)
The cells A1, a cell A2, and up to the cell An are all cells in the grid a, the average value of the coverage levels of the first frequency band corresponding to the cell A1 is the average value of the coverage levels of the first frequency band included in all MR information in the cell A1, the average value of the coverage levels of the first frequency band corresponding to the cell A2 is the average value of the coverage levels of the first frequency band included in all MR information in the cell A2, and similarly, the average value of the coverage levels of the first frequency band corresponding to the cell An is the average value of the coverage levels of the first frequency band included in all MR information in the cell An.
S102, according to the coverage levels of the plurality of different first frequency bands corresponding to the grid, the coverage level of the second frequency band corresponding to the grid is obtained.
In this embodiment of the application, the second frequency band is a frequency band of a second communication system, and the second communication system is a communication system different from the first communication system, for example, the first communication system may be a fourth-generation mobile communication technology 4G, and the second communication system may be a fifth-generation mobile communication technology 5G.
In a possible implementation manner, the following calculation is performed for each grid, respectively, to obtain a coverage level of a second frequency band corresponding to the grid:
first, for each first frequency band, the coverage level of the second frequency band corresponding to the first frequency band is obtained according to the coverage level of the first frequency band and the mapping relation between the coverage level of the first frequency band and the coverage level of the second frequency band.
For example, the mapping relationship between the coverage level of the first frequency band and the coverage level of the second frequency band may include: a coverage level difference between the coverage level of the first frequency band and the coverage level of the second frequency band.
Illustratively, the coverage level difference may be determined from historical drive test data. Specifically, for an area commonly covered by a first frequency band and a second frequency band, a test level of the first frequency band and a test level of the second frequency band are respectively obtained, and then, the coverage level difference is determined according to a difference between the test level of the first frequency band and the test level of the second frequency band. The external environment is always kept consistent when the test level of the first frequency band and the test level of the second frequency band are obtained; for example, for an indoor environment, a test level of a first frequency band and a test level of a second frequency band in the indoor environment are respectively obtained, and a coverage level difference value belonging to the indoor environment is obtained according to the test level of the first frequency band and the test level of the second frequency band in the indoor environment; and aiming at the outdoor environment, respectively acquiring the test level of the first frequency band and the test level of the second frequency band in the outdoor environment, and acquiring the outdoor coverage level difference value according to the test level of the first frequency band and the test level of the second frequency band in the outdoor environment.
In practical application, a large amount of drive test data in a preset time period can be subjected to statistical analysis, so that a coverage level difference value with higher accuracy is obtained. For example, a plurality of sets of drive test data acquired in the same environment in one month are respectively calculated, and an average value of the coverage level differences corresponding to the plurality of sets of drive test data is determined as the coverage level difference between the coverage level of the first frequency band and the coverage level of the second frequency band.
In this step, the coverage level difference between the coverage level of the first frequency band and the coverage level of the second frequency band may be obtained according to the historical drive test data, and it is not necessary to consume manpower and material resources to perform special measurement when the coverage status of the second communication system network is obtained, thereby reducing the cost.
And then, according to the coverage levels of the second frequency bands respectively corresponding to the plurality of different first frequency bands, obtaining the coverage level of the second frequency band corresponding to the grid. For example, weighting processing may be performed according to the coverage levels of the second frequency bands corresponding to the plurality of different first frequency bands, so as to obtain the coverage level of the second frequency band corresponding to the grid, where in the weighting processing, a weighting coefficient of the coverage level of the second frequency band corresponding to each first frequency band is: the ratio of the number of the sampling points corresponding to the first frequency band to the sum of the numbers of the sampling points corresponding to the different first frequency bands.
The grid of the target area may be an indoor grid or an outdoor grid, and the calculation method for obtaining the coverage level of the second frequency band corresponding to the indoor grid according to the coverage levels of the plurality of different first frequency bands corresponding to the indoor grid is similar to the calculation method for obtaining the coverage level of the second frequency band corresponding to the outdoor grid according to the coverage levels of the plurality of different first frequency bands corresponding to the outdoor grid.
In this step, for each grid, the obtained coverage level of the second frequency band can accurately reflect the wireless network coverage condition of the second frequency band in the grid by performing weighting processing on the coverage levels of the second frequency bands respectively corresponding to a plurality of different first frequency bands of the grid, the calculation mode of weighting processing is simple, and the data processing efficiency can be ensured to be high by adopting weighting processing.
S103, acquiring the coverage condition of the second communication system network of the target area according to the coverage level of the second frequency band corresponding to each grid in the target area.
In this step, the coverage level of the second frequency band corresponding to each grid in the target area may be statistically analyzed to obtain the coverage condition of the second communication system network in the target area, and for example, the statistical analysis of the coverage level of the second frequency band corresponding to each grid in the target area may be a statistical analysis of the number of grids whose coverage levels meet the operation and maintenance requirements.
When the statistical analysis is performed on the number of grids whose coverage levels of the second frequency band in the target region meet the operation and maintenance requirements, the statistical analysis can be specifically realized by the following method: and determining the number of grids with the coverage level of the second frequency band being greater than or equal to the preset threshold according to the coverage level of the second frequency band corresponding to each grid in the target area and the preset threshold, and determining the coverage condition of the second communication system network in the target area according to the ratio of the number of grids with the coverage level of the second frequency band being greater than or equal to the preset threshold to the total number of grids in the target area.
Of course, in the embodiment of the present application, obtaining the coverage status of the second communication system network in the target area according to the coverage level of the second frequency band corresponding to each grid in the target area may also be implemented in other manners, which is not limited in the embodiment of the present application. The coverage condition of the second communication system network, which is obtained according to the coverage level of the second frequency band obtained in the embodiment of the present application and obtains the target area according to the obtained coverage level of the second frequency band, belongs to the protection scope of the present application.
Here, the target area grid may be an indoor grid or an outdoor grid, and a coverage level difference between a first frequency band and a second frequency band belonging to the indoor grid is different from a coverage level difference between the first frequency band and the second frequency band belonging to the outdoor grid.
