Problems solved by technology

However, this method has the following disadvantages: 1. The coverage of wireless radio frequency is complicated, and there are influencing factors such as refraction, scattering and diffraction. The geometric method is used to calculate the overlap of coverage area, and the relationship between the wireless base station and the geographic feature entity cannot be accurately calculated; 2. This method cannot establish the relationship between the wireless base station and the geographic feature entity for line-segment geographic features such as roads

Embodiment

[0062] A method for establishing a correlation matrix between a wireless base station and a line-segment geographical feature provided by the present invention, the specific steps are:

[0063] S1. Extract training data TrainData from mobile operator big data;

[0064] Utilizing the pipeline data of the mobile operator, the signaling data can be collected from the A / Iu / S1-MME and other control plane interfaces of the mobile operator's 2G / 3G / 4G network, and the location data can be obtained through data conversion, that is, the communication of each user The location, time, and duration of the base station where the event occurred.

[0065] The Internet data flow can be collected from the Gb / IuPS / Gn / S1-u user plane interface of the mobile operator's 2G / 3G / 4G network, and the user's Internet traffic data can be obtained through data conversion. With the development of the mobile Internet, a large number of LBS-based APPs will report the latitude and longitude. By decoding these...

Abstract

The invention belongs to the technical field of data analysis, and particularly relates to a method for establishing a correlation matrix of a wireless base station and a line segment type geographic ground object. The method comprises the following steps: extracting training data; extracting and establishing ground object information; segmenting the line segment type ground object; associating the TrainData with the PoiData through a geographic relationship; establishing a relation matrix Rcp _ train and Rpc _ train based on the training data; calculating the coverage intensity from each wireless base station cell to each segment point by using a propagation model, and deducing the coverage probability; establishing a coverage probability matrix Rline _ cov from all cells to all segmentation points; calculating an adjoint trusted matrix Bline of the training matrix; integrating the three matrixes of Rpc _ train, Rline _ cov and Bline to establish a cell-ground object a relation matrix Rline; and updating the relation matrix Rline by adopting a periodic sliding window method. The method provides basic data for social geographic information for the mobile phone user after accurately judging the residence place of the mobile phone user, and provides a basic model for public security, disaster prevention and reduction, smart cities, marketing and other personnel position-based applications.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and in particular relates to a method for establishing a correlation matrix between a wireless base station and a line-segment geographical object. Background technique [0002] In the process of applying big data of operators, it is often necessary to map base station information to specific geographical features to provide a data basis for further analysis of mobile phone users' social location attributes. [0003] With the continuous development of short-range wireless communication and mobile network technology, location-based service (location-based service, LBS) has attracted more and more attention. The global positioning system (globalpositioningsystem, GPS) can already provide position information outdoors, but it cannot work properly in indoor environments due to the characteristics of buildings’ occlusion and high floor density. In this case, there have been indoor positioning s...
