Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method aims at solving the problems that the coverage scene information of the base station is not completely acquired, not timely classified, inaccurate and the like due to the adoption of a method for manually determining the coverage scene of the base station in the prior art. The scheme is provided.
The method for determining the coverage scenario of the base station according to the present invention is described below with reference to fig. 1.
Fig. 1 is a flowchart of an embodiment of a method for determining a coverage scenario of a base station according to the present invention. As shown in fig. 1, the method of this embodiment includes:
step S102, determining the coverage area of the base station.
Specifically, the coverage radius of the base station is determined, the geographical position information of the base station is converted into the geographical position information in the electronic map, and finally the coverage range of the base station in the electronic map is determined according to the geographical position, the coverage radius and the coverage model of the base station in the electronic map.
For example, the coverage radius of the base station is determined according to a free space propagation loss model, which has the following formula:
Los(dB)＝32.44+20logD(km)+20logF(MHz) (1)
wherein Los is propagation loss, D is transmission distance, and has a unit of km, F is operating frequency, and has a unit of MHz. The transmission distance D can be obtained according to the propagation loss Los and the working frequency F, the propagation loss Los can be obtained according to the receiving sensitivity, the antenna gain and the atmospheric attenuation, and the receiving sensitivity, the antenna gain and the working frequency F can be obtained through information such as configuration parameters and working parameters of the base station, so that the coverage radius of the base station can be obtained according to the configuration parameters and the working parameters of the base station, and different propagation loss models can be adopted to calculate the coverage radius of the base station according to actual requirements.
The geographical position information of the base station is GPS information of the base station, the position of the base station is a central point of a coverage range of the base station, and because the GPS longitude and latitude recorded by the base station possibly have deviation with the longitude and latitude in the electronic map (the longitude and latitude geographical coordinate systems adopted by different positioning methods are different), in order to improve the accuracy of determining the coverage scene of the base station, the GPS longitude and latitude recorded by the base station is converted into the longitude and latitude in the corresponding electronic map. At present, the commonly used electronic map has editing data for different areas or positions, and the latitude and longitude information of the base station can be converted into the latitude and longitude information in the electronic map by calling an Application Programming Interface (API) of the electronic map through the editing data of the area or position closest to the base station.
And determining the central point of the coverage range of the base station, namely latitude and longitude information of the base station on the electronic map, and the coverage radius of the base station, and determining the coverage range of the base station on the electronic map through the coverage model of the base station. The coverage model of the current base station includes: the coverage models such as regular hexagon in the cellular networking mode and circle in other networking modes can be selected according to actual requirements to calculate the coverage range of the base station.
And step S104, searching the interest point information in the coverage range of the base station on the electronic map.
Specifically, search tags corresponding to various coverage scenes of the base station are obtained, the search tags are used as keywords to search in the coverage range of the base station on the electronic map, and the interest point information corresponding to the search tags in the coverage range of the base station is obtained.
The point of interest (POI) information of the electronic map includes longitude and latitude of the point, a city to which the point belongs, a name of the point, a category to which the point belongs, and the like. The interest points and the categories of the interest points may be different on different electronic maps, for example, the categories of the interest points include: markets, supermarkets, food stores, railway stations, airports, hospitals, schools, primary schools, and the like. The classification condition of the interest points in the electronic map can be called through an API of the electronic map, and the search labels corresponding to various coverage scenes of the base station are defined by referring to the classification condition of the interest points and the names of the interest points. For example, if the coverage scene division granularity of the base station is coarse, each coverage scene of the base station may correspond to multiple search tags, each search tag corresponds to a category of the interest point, and if the coverage scene division granularity of the base station is fine, each coverage scene of the base station corresponds to one search tag, and the search tags may be keywords in the names of the interest points. In addition, the division of the search labels of different levels corresponding to the coverage scenes of the base stations of different levels can be constructed, and the search labels of different levels are selected for searching according to actual requirements, for example, the primary coverage scene of the base station is a scenic spot, and the secondary coverage scene is a 5A-level scenic spot. The generated search tags are put into an array, each search tag in the array is traversed in the range of all base stations determined on the electronic map for searching, and if the interest points matched with the search tags exist, the information of the interest points is returned, so that the search can be simultaneously carried out in the coverage range of all base stations nationwide, and the efficiency is higher.
And step S106, determining the coverage scene of the base station according to the interest point information located in the coverage range of the base station in the electronic map.
Specifically, if the search is performed within the coverage range of the base station on the electronic map by using the search tag as the keyword, and the interest point information corresponding to the search tag is obtained, the search tag is mapped to the coverage scene of the base station.
For example, the search tag is a school, and the school is used as a keyword to search in the coverage area of the base stations on the electronic map, so that the point-of-interest information returned in the coverage area of some base stations is obtained, and the coverage scenes of the base stations include the coverage scenes corresponding to the school. The determined coverage scene is added to a base station Information database for storage, and can be displayed through a GIS (Geographic Information System). In addition, the coverage scene of the base station needs to be periodically updated, so that inaccurate coverage scene information of the base station caused by newly building the base station, moving the base station and changing the information of the interest points is avoided.
According to the method, the coverage range of the base station is automatically determined, the interest point information in the coverage range of the base station is automatically searched by using the electronic map, the coverage scene of the base station is automatically determined according to the interest point information, the automatic determination of the coverage scene of the base station is realized, the labor is saved, meanwhile, the method is not influenced by geographic environment and human factors, the coverage scene of any base station can be determined, and the comprehensiveness, timeliness and accuracy of the coverage scene information of the base station are improved.
Another embodiment of the method for determining the coverage scenario of the base station in the present invention is described below with reference to fig. 2.

When building the base station, the geographical position of the base station is preset, the coverage area of the base station is estimated according to the preset configuration parameters of the base station, the coverage scene of the base station is further determined, and the steps S102 to S106 are referred to. The coverage scenes of the base station are divided into different categories according to the conditions of the traffic, population density, traffic characteristics and the like, for example, a major coverage scene, a minor coverage scene, a time-share coverage scene, a high-speed coverage scene and the like, a plurality of coverage scenes such as schools, supermarkets and the like can be included in the coverage range of one base station, and further, the positions of various coverage scenes in the coverage range of the base station can be determined, for example, the distance between the center point of various coverage scenes and the geographical position of the base station is used as a measurement standard of the positions of the coverage scenes in the coverage range of the base station. The method comprises the steps of selecting a site for the construction of a base station according to the type of a coverage scene contained in the coverage range of the base station and the position of the coverage scene in the coverage range of the base station, for example, a key coverage scene cannot be located at the edge of the coverage range of the base station, setting a distance threshold between the center point of the coverage scene of the base station and the geographic position of the base station, reselecting the construction position of the base station or newly adding the base station for coverage under the condition that the threshold is not met, repeating the process, and judging the coverage scene of the base station again until various coverage scenes in the coverage range of the base station meet preset conditions. Further, configuration parameters of the base station may also be adjusted according to a coverage scenario of the base station, for example, a key coverage scenario is located at an edge of a coverage area of the base station, and a transmission power of the base station may be adjusted to enhance coverage of the key coverage scenario, for example, a high-speed coverage scenario needs to consider switching of the base station, and for example, a coverage scenario such as a mall is adjusted at different time intervals, and a sleep time interval of the base station may be configured to save power.
The coverage scene of the base station is utilized to provide a basis for the site selection of the base station, the configuration of parameters and the like, and compared with the prior art that the site selection of the base station needs manual field investigation, the efficiency is improved.
Step S210, optionally, determining an optimization and guarantee level of the base station according to the coverage scenario of the base station, and selecting a method and a period for optimizing or monitoring the base station according to the optimization and guarantee level of the base station.
The coverage scenes of the base station are divided into different levels corresponding to different optimization or guarantee levels according to the conditions of people flow, population density, people flow characteristics and the like, for example, higher optimization or guarantee levels are required to be set for coverage scenes with higher population density, such as schools, office buildings and the like, and corresponding optimization or monitoring methods and periods are selected at the same time.
Compared with the prior art that a large number of DT (driver test) tests are manually carried out to determine the base station network elements needing optimization and guarantee and further determine the optimization or guarantee schemes of the base station network elements, the efficiency is improved, and the cost is saved.
