一种基于终端测量上报信息的无线定位方法研究及实现

Research and Implementation of Wireless Location-Positioning Method based on User-Equipment Measurement Report

介绍一种基于终端测量上报信息的无线定位方法,并给出了基于Python的实现方法。步骤一:结合终端上报的AGPS及RSCP信息,采用Python提取数据并构建基础数据库,而构建基础数据库的主要步骤包括异常数据剔除、确定上报信息归属栅格和数据更新。步骤二:对无AGPS上报的终端,利用其RSCP信息和基础数据中的数据,按照最小距离方法进行匹配,并根据匹配结果定位出终端所在栅格,完成目标终端的定位。结果显示,基于终端测量上报的无线定位方法在无线定位优化中具有一定的参考意义。

The wireless location method based on terminal measurement and reporting information is described,and the implementation method based on Python also given.Firstly,combined with the AGPS and RSCP information reported by the terminal,Python is used to extract data and build up the basic database.The main steps for building up the basic database include abnormal data elimination,determination and reporting of information attribution grid,and data updating.Then,for AGPS-free terminals,their RSCP information and basic data are used to make match in accordance with the minimum distance method.Then according to the matching result,the grid of the terminal is located,and the locating of the target terminal completed.The experiment results indicate that the wireless location method based on terminal measurement is of certain reference value for wireless location optimization.
