摘要

本文主要研究传统GSM(全球移动通信系统)手机的位置估计问题。提出了三种基于网络的软件定位方法，利用GSM中可用的小区识别(CI)、时序提前(TA)和接收信号强度(RXLEV)信息，并讨论了它们的实现。给出了该方法在GSM商用网络中的实验性能，并进行了对比分析。结果表明，最精确的定位方法的定位误差倾向于按平均单元尺寸缩放。

Experimental performance of methods to estimate the location of legacy handsets in GSM

This paper focuses on the location estimation of legacy GSM (Global System for Mobile communications) handsets. Three network-based software location methods using CI (cell identity), TA (timing advance), and RXLEV (received signal strength) information available in GSM are presented and their implementation is discussed. Experimental performance of the methods in a commercial GSM network is presented and a comparative analysis is carried out. It is shown that the location error of the most accurate method tends to scale according to the average cell size.
