In the prior art, when an operator wants to obtain location information of a base station, a manual acquisition mode is usually adopted, that is, GPS location information of the base station is acquired on the spot by manually holding a device with a GPS function to the location of the base station. This approach not only consumes labor cost, but also the accuracy of the collected base station location information is often very low.
In view of the above technical problems, the inventors of the present application found that: in the coverage area of the base station, the terminal device communicates with the base station to generate mobile data, and the mobile data can reflect the relationship between the terminal device and the position of the base station from the side, for example, the strength of a signal received by the terminal device is related to the distance between the terminal device and the base station, and the coverage area of the base station can be divided into a plurality of sectors. Therefore, manual on-site collection can be avoided, and the data are objectively data without being influenced by human, so that the base station position determined according to the data is higher in accuracy.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a base station positioning method according to an embodiment of the present application. The embodiment of the present application provides a base station positioning method for solving the above technical problems in the prior art, and as shown in fig. 2, the method specifically includes the following steps:
step S201, mobile data of a plurality of terminal devices accessed by the base station to be positioned is obtained.
The mobile data of each terminal device includes an identifier of a base station cell corresponding to the terminal device.
In this embodiment, the relationship between the base station and the base station cell is specifically as follows:
as shown in fig. 3, in a cellular communication network, each base station generally has three sectors, and each sector transmits signals to a certain direction and covers a certain range. For example, one of the sector antennas is aligned to the north direction, and the coverage area is 120 degrees; the other sector is aligned to the southeast direction, and the coverage range is 120 degrees; and one sector is aligned to the southwest direction, and the coverage range is 120 degrees. Thus, three sectors can perform 360-degree full coverage on the periphery of the base station. The above-mentioned one sector can be regarded as one base station cell, and the base station cell of each base station has an identifier for uniquely distinguishing the base station cells.
For example, the terminal device located in the coverage area of the base station may generate a Measurement Report (MR) at intervals, send the MR to a sector corresponding to the terminal device, and receive and store the MR to the network management system of the base station through the antenna of the sector. The measurement report includes movement data of the terminal device.
An execution main body of the method of this embodiment may be an electronic device as shown in fig. 1, where the electronic device may obtain a measurement report within a period of time from a network management system of a base station, so as to obtain mobile data of a plurality of terminal devices accessing the base station to be located, where the mobile data includes an identifier of a base station cell where the terminal device is located, and is used to uniquely identify the base station cell where the terminal device is located in the base station.
Step S202, clustering the terminal equipment according to the identification of the base station cell corresponding to each terminal equipment to obtain a plurality of clustering results, wherein the terminal equipment in each clustering result corresponds to the identification of the same base station cell.
The method comprises the steps of clustering terminal equipment of the same base station cell together to obtain a clustering result, and obtaining a plurality of clustering results by a plurality of base station cells. For example, the identifier of the base station cell includes base station cell identifier 1, base station cell identifier 2, and base station cell identifier 3, terminal device 1, terminal device 2, and terminal device 3 correspond to base station cell identifier 1, terminal device 4, terminal device 5, and terminal device 6 correspond to base station cell identifier 2, and terminal device 7, terminal device 8, terminal device 9, and terminal device 10 correspond to base station cell identifier 3; then, the terminal devices corresponding to the base station cell identifier 1, the base station cell identifier 2, and the base station cell identifier 3 are clustered, that is, the terminal device 1, the terminal device 2, and the terminal device 3 are clustered, the terminal device 4, the terminal device 5, and the terminal device 6 are clustered, the terminal device 7, the terminal device 8, the terminal device 9, and the terminal device 10 are clustered, so as to obtain three clustering results, and each base station cell corresponds to one clustering result.
And step S203, determining the position information of the base station according to the plurality of clustering results.
In this embodiment, each clustering result corresponds to one base station cell, and for the same base station, certain relationships exist among the base station cells, and the position information of the base station can be obtained by analyzing and processing a plurality of clustering results.
The method comprises the steps that mobile data of a plurality of terminal devices accessed by a base station to be positioned are obtained, wherein the mobile data of each terminal device comprises an identifier of a base station cell corresponding to the terminal device; clustering the terminal equipment according to the identification of the base station cell corresponding to each terminal equipment to obtain a plurality of clustering results, wherein the terminal equipment in each clustering result corresponds to the identification of the same base station cell; and determining the position information of the base station according to the plurality of clustering results. Because the position information of the base station is determined according to the mobile data of the plurality of terminal devices, the manual handheld GPS device is not needed to collect the position information of the base station on the spot, the labor cost is saved, and the positioning accuracy of the base station is improved.
In an alternative embodiment, the mobile data further includes location information of the terminal device and a level value of the base station cell.
Step S202 specifically includes:
step a1, fitting the position information of the terminal equipment with the same base station cell identification in the plurality of terminal equipment with the level value of the base station cell to obtain a plurality of fitting results.
In this embodiment, the level value of the base station cell refers to a level value of a base station cell signal received by the terminal device, and may be obtained from the measurement report MR. Likewise, the location information of the terminal device can also be obtained from the measurement report MR.
And the fitting result corresponding to the identifier of the base station cell is used for expressing the relation between the position of the terminal equipment in the base station cell and the level value of the base station cell. By fitting the position information of the terminal device and the level value of the base station cell, a relationship between the position information of the terminal device and the level value of the base station cell can be obtained, which may be a functional relationship.
For example, the base station includes base station cell 1, base station cell 2, and base station cell 3; the coverage area of the base station cell 1 includes terminal device 1, terminal device 2, and terminal device 3 …, where N is an integer greater than 0, and the location information of each terminal device and the level value of the signal received by the terminal device from the base station cell 1 can be regarded as one point, so that N terminal devices correspond to N points, and the N points are connected by using a smooth line, so that 1 fitting result can be obtained. Similarly, the base station cell 2 and the base station cell 3 may also respectively obtain corresponding fitting results by using the above method.
And a2, determining the position information of the base station according to the plurality of fitting results.
For the same base station, certain relation exists among the base station cells, and the position information of the base station can be obtained by analyzing and processing a plurality of clustering results. The fitting results reflect the relationship between the position of the terminal device in the base station cell and the level value of the base station cell, which is related to the position of the base station, and therefore, the position information of the base station can be derived from these fitting results.
In cellular mobile communication, the strength of the signal is related to the distance, and the relationship between the position information of the terminal device and the level value of the base station cell may include: the distance between the terminal equipment and the base station is inversely related to the level value of the base station cell. That is, the farther the terminal device is from the base station, the lower the level value of the base station cell, whereas the closer the terminal device is to the base station, the higher the level value of the base station cell. The relationship between the distance between the terminal device and the base station and the level value of the base station cell can be regarded as a linear relationship, and if the position information of the terminal device and the level value of the base station cell are expressed by a two-dimensional coordinate system, the fitting result is a straight line in the two-dimensional coordinate system. Specifically, step a1 includes:
step a11, classifying the position information of the terminal device and the level value of the base station cell according to the identification of the base station cell to obtain a plurality of classification data.
Each category data corresponds to an identifier of a base station cell, and each category data includes location information of a plurality of terminal devices and a level value of the base station cell.
In this embodiment, the terminal devices are classified according to the identifier of the base station cell, the terminal devices in the same base station cell are classified into a class, and the position information of the terminal device corresponding to the class and the level value of the base station cell are one class of data.
Step a12, for each category data, the position information of a plurality of terminal devices and the level value of the base station cell are fitted to a unitary linear regression line.
For example, the base station includes a base station cell 1, a base station cell 2, and a base station cell 3, and after the classification in step a11, the base station cell 1, the base station cell 2, and the base station cell 3 respectively obtain category data 1, category data 2, and category data 3. Taking base station cell 1 as an example, it is assumed that category data 1 includes location information of terminal device 1 and level value 1 of base station cell 1, location information of terminal device 2 and level value 2 of base station cell 1, location information of terminal device 3 and level value 3 of base station cell 1; then, according to the position information of the terminal device 1 and the level value 1 of the base station cell 1, the position information of the terminal device 2 and the level value 2 of the base station cell 1, the position information of the terminal device 3 and the level value 3 of the base station cell 1 can be fitted to obtain a unary linear regression straight line. Similarly, the base station cell 2 and the base station cell 3 may obtain a unary linear regression line.
As shown in fig. 4, in step a12, the level value of the base station cell is taken as the Y axis of the vertical axis, the location information of the terminal device is taken as the X axis of the horizontal axis, and each point in the figure represents the location information of the terminal device within the coverage area of the same base station cell and the level value of the base station cell corresponding to the location information of the terminal device.
The above-mentioned unary linear regression relationship can be expressed as the following equation:
Y＝A+BX；
in the formula, Y is a level value of a base station cell, X is a distance from a terminal device to the base station, B represents a linear relationship between the distance from the terminal device to the base station and the level value of the base station cell, and a is a level value of a base station cell corresponding to a situation where the base station is located when X is 0 in a coverage propagation model, that is, an intercept on a vertical axis in the figure, and may also be understood as a level value received when the terminal device is located at a base station position.
The above embodiment describes a specific implementation of the clustering process in step S202, and how to determine the location information of the base station according to the fitting result after obtaining the fitting result will be described below.
In an alternative embodiment, step a2 includes: generating a triangle according to a plurality of unary linear regression lines; determining the gravity center position of the triangle; the gravity center position of the triangle is used as the position information of the base station.
As shown in fig. 5, a straight line AB, a straight line AC, and a straight line BC respectively represent linear regression straight lines of 3 base station cells, and in practice, since the amount of data collected at a point is limited, a triangle may not be directly obtained, therefore, in this embodiment, three linear regression straight lines may be extended to intersect two by two, so as to obtain a triangle ABC, where AA ', BB ' and CC ' respectively represent central lines of three line segments BC, AC, and AB, and the position information corresponding to the intersection O of the three central lines is the position information of the base station.
In another alternative embodiment, step a2 includes: determining position information of intersection points of a plurality of unary linear regression lines; the position information of the intersection point is used as the position information of the base station.
As shown in fig. 6, a straight line AB, a straight line AC, and a straight line BC respectively represent linear regression straight lines of 3 base station cells, and in practice, since the amount of data collected at a point is limited, a triangle may not be directly obtained, therefore, in this embodiment, three linear regression straight lines may be extended to intersect two by two, so as to obtain a triangle ABC, where AA ', BB ' and CC ' respectively represent bisectors of three interior angles of the triangle, and the position information corresponding to an intersection O of the three bisectors is the position information of the base station.
The base station position information obtained by the above embodiment is theoretical base station position information, and whether the actual installation position of the base station is accurate can be determined by comparing the theoretical base station position information with the actual installation position of the base station, thereby providing a reference for an operator. Optionally, after step S203, the method of this embodiment further includes:
step S204, determining whether the difference value between the position information of the base station and the actual installation position information of the base station is smaller than a preset threshold value.
And step S205, if yes, determining that the actual installation position information of the base station is accurate.
And step S206, if not, determining that the actual installation position information of the base station is inaccurate, and sending prompt information.
It should be noted that, the above step S205 and step S206 do not limit the execution order of the steps, and may be to execute step S205 first and then execute step S206, or execute step S206 first and then execute step S205, which is not specifically limited in this embodiment.
For example, the location information of the base station is denoted as P, the actual installation location information of the base station is denoted as P _ base station parameter library, and the preset threshold value is denoted as V; the P _ base station engineering parameter base can be determined according to the current network installation position information of the base station stored in the current network base station engineering parameter basic database; then, calculating the working parameter base | of the P-P _ base station to obtain the error range of the calculated position; if the position error range is smaller than a preset threshold value V, the base station installation position data in the base station engineering parameter database is accurate; otherwise, the base station installation position data in the base station engineering parameter database is considered to have problems, and prompt information can be sent to suggest field check.
In the embodiment, by comparing the theoretical base station position information with the actual installation position of the base station, whether the actual installation position of the base station is accurate can be determined, so that reference is provided for an operator. Therefore, whether the base station position installation is accurate or not can be automatically detected.
