Abstract: A kind of Cell-ID positioning method is put forward based on linear weight and Google base station database. All of the signal strength and position of the base stations received by the mobile terminal are utilized and it only needs to update the software of the terminal. The result shows that the accuracy is less than 150 m under 2s circumstances and it is more suitable for LBS.

摘要： 基于Google基站数据库, 提出一种基于线性加权的Cell-ID定位方法, 以综合利用智能移动终端在定位时所能接收到的小区基站的信号强度和相应的小区基站坐标等信息。该方法仅需要升级智能终端软件就可以实现定位。 实验表明, 在2??要求下, 定位误差小于150 m, 可以满足精度要求比较低的基于位置的服务的应用需求。
