Problems solved by technology

[0003] There is randomness in the method of accessing the base station by the user's mobile phone, that is, the same location may cause the user to visit different base stations due to uncertain factors such as the number of people in the location, so using the location of the base station to mark the user's location will lead to a huge error
By searching for multiple base stations accessed by the user's mobile phone, since the coverage of the base station signal often does not include the location of the base station, it is often inaccurate to determine the user's visiting location. Although the weighted centroid is calculated, it will also be affected by the base station parameters (such as latitude and longitude)
[0004] To sum up, when the above method is used to locate the user's visiting location, the positioning will be inaccurate, so that the user's visiting location cannot be accurately obtained

Embodiment 1

[0064] figure 1 It is a flowchart of a method for locating a user's visited location provided by Embodiment 1 of the present invention.

[0065] refer to figure 1 , the method includes the following steps:

[0066] Step S101, obtaining the latitude and longitude of the destination;

[0067] Step S102, constructing a data set according to the latitude and longitude of the destination;

[0068] Here, by acquiring the latitude and longitude of the destination, user signaling data within a preset range is searched according to the latitude and longitude of the destination, where the preset range may be 3 kilometers. Among the user signaling data within a preset range, the base station with the most number of visits is defined as a primary base station (Primary Cell, PC) denoted by PC, and a base station (Cell, C) denoted by C. Count the frequency of user access to the base station in the user signaling data, and construct a data set according to the frequency of user access to...

Abstract

The invention provides a method and device for positioning a visited position of a user. The method comprises the following steps: acquiring longitude and latitude of a destination; constructing a data set according to the destination longitude and latitude; clustering the data set through an elbow method to obtain a plurality of ethnic classes; according to the longitude and latitude corresponding to each base station in each ethnic class and the visit frequency corresponding to each base station, calculating a weighted centroid corresponding to each base station in each ethnic class; based on the weighted centroid corresponding to each base station in each ethnic class, selecting the weighted centroid closest to the longitude and latitude of the destination, and taking the ethnic class corresponding to the weighted centroid closest to the longitude and latitude of the destination as a target ethnic class; constructing a decision tree model according to the target ethnic class; according to the decision tree model, respectively calculating the probability of visiting the destination of the user accessing the master base station and the probability of visiting the destination of the user accessing the slave base station, and calculating the probability of visiting the destination of the user; determining the visited position of the user according to the probability that the user visits the destination, and therefore the visiting position of the user can be accurately positioned.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for locating a user's visited location. Background technique [0002] At present, the method of judging the user's visit is to use the user's mobile phone to access the base station signaling, and then match the longitude and latitude of the base station's industrial parameters, so as to determine the user's visiting location according to the location of the base station. In addition, it is also possible to find multiple base stations visited by the user's mobile phone, and calculate the weighted centroid to locate the user's visiting location according to the latitude and longitude of the base station's industrial parameters and the visit frequency of the base station. [0003] The method of accessing the base station by the user's mobile phone has randomness, that is, the same location may cause the user to visit different base stations due to uncer...
