摘　　要：首先介绍移动通信系统中无线定位技术的应用 ,然后讨论了几种常用的无线定位方案 ,并较详细地介绍了基于时间的两种方案 TOA及 TDOA的定位算法 ,并指出了在无线定位技术中遇到的几个难点 ,介绍了部分的解决手段并指出了有待进一步研究的方向。In this paper, the application of radio location technology to cellular subscribers in wireless mobile system is introduced and several widely used wireless location schemes are discussed. Then, two location techniques based on time of arrival (TOA) and time differences of arrival (TDOA) are introduced in detail. And several problems in radio location technology are pointed out and some solutions to the problems are also given and some further investigative issues are mentioned by the authors.
