Problems solved by technology

This method has the following disadvantages: the coverage area of ​​the base station is large, and there is an intersection between the base stations, and the user may be located in the coverage area of ​​two base stations at the same time, which leads to inaccurate user trajectory analysis; in addition, in the actual collection of signaling In the data, due to the problem of the signal technology itself, there will be points that are extremely far away for a moment, which seriously affects the accuracy of user trajectory analysis

Embodiment Construction

[0062] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0063] Such as figure 1 Shown is a flow chart of the user trajectory analysis method in the embodiment of the present invention, including the following steps:

[0064] Step 101, acquire signaling data of a user; the signaling data includes: time information, space information, and user ID.

[0065] The signaling data is generally provided by the operator, and the spatial information in it may be cell information or base station information. For 2G or 3G networks, operators can directly provide cell information, but for 4G networks, operators provide base station information. The cell information usually includes cell ID, longitude, latitude, and coverage radius; the base station information usually includes: ...

Abstract

The invention discloses a user trajectory analysis method and system. The method comprises the steps that the signaling data of a user are acquired, wherein the signaling data include time information, space information and the user ID; user trajectory point information corresponding to each user ID is obtained according to the signaling data, wherein the user trajectory point information includes trajectory point acquisition time, the located cell ID, the cell longitude and the cell latitude; the abnormal data in the user trajectory point information are eliminated; and mobile point pairs in the user trajectory points after elimination of the abnormal data are determined so that mobile trajectory sequences are obtained. The accuracy of user trajectory analysis can be enhanced by the user trajectory analysis method and system.

Description

technical field [0001] The invention relates to the field of data mining, in particular to a user track analysis method and system. Background technique [0002] In recent years, with the popularization of smart devices and the rapid development of data collection, processing, and analysis technologies, user data has attracted more and more attention from various companies, especially those involved in traffic analysis, user recommendation, and other related businesses. At present, the main data sources used for user trajectory analysis include GPS data, user location data obtained by SDK (Software Development Kit, software development kit), and signaling data collected by base stations provided by operators. Among them, GPS data positioning is relatively accurate, but its data is too dense and complicated to analyze and process; the SDK data collection interval is long, and the user trajectory analyzed from this is inaccurate; although the accuracy of signaling data is slig...
