Problems solved by technology

The first way is through the GPS hardware module of the mobile terminal, which is mainly limited by the need for user participation and the need to open the hardware module; while the technology of using the traditional three-point positioning method to realize user positioning is affected by changes in wireless signal propagation (non-line-of-sight propagation, multiple diameter, interference, etc.) positioning accuracy is poor

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0030] The mobile phone communicates with the base station and provides the signal data of the base station to the figure 1 The positioning system shown, the mobile phone signal data format is as follows figure 2 shown.

[0031] should be established in advance Figure 4 The base station basic information table shown includes the latitude and longitude of each base station, the direction angle of each sector, and the tower height.

[0032] Such as figure 1 Shown: By collecting wireless network user wireless measurement reports and bills for association, at the same time refer to the basic information table of the base station including the longitude and latitude of the base station, the direction angle of the cell, and the height of the tower. Process the collected dat...

Abstract

The invention discloses a method for locating a mobile user based on cell frequency weighting in a period of time. The method comprises the steps of 1, carrying out data analysis through parameters such as service cell IDs and adjacent cell IDni in a wireless measurement report in a special period of time; 2, calculating cell locations according to parameters such as base station locations, cell antenna direction angles and tower height; and 3, training the special period of time by employing a machine learning method. According to the method, development of a light location platform is realized; the construction investment of the location platform is reduced; the problem that the location precision of a triangular location mode is poor is solved; and the method can be applied to acquisition of a user location attribute in a mobile environment, description of user tracks through assistance of time stamps and analysis of passenger flow volume.

Description

technical field [0001] The invention relates to a method for realizing mobile user positioning based on cell frequency weighting within a time period, and belongs to the field of data mining and analysis in mobile communication. Background technique [0002] At present, the relevant technologies for positioning of mobile users generally use the GPS module in the hardware of the mobile terminal to collect corresponding latitude and longitude information through the client or the three-point positioning technology through wireless transmission. The first way is through the GPS hardware module of the mobile terminal, which is mainly limited by the need for user participation and the need to open the hardware module; while the technology of using the traditional three-point positioning method to realize user positioning is affected by changes in wireless signal propagation (non-line-of-sight propagation, multiple diameter, interference, etc.) positioning accuracy is poor. Cont...
