摘要
Cellid定位是3GPP推荐的最简单的一种定位技术,通过获取移动终端的Cellid+LAC位置信息,进一步调用地图展现接口(如Google地图等)来实现定位展现。为了纠正地图定位展现中的位置偏移,结合基站信息获取"三角公式法",研究并提出了一种消除位置偏移算法来实现更精确定位。
Cellid positioning is the simplest positioning technology recommended by 3GPP which realizes positioning function by acquiring the Cellid＋LAC location information of mobile terminal and calling the interface of map locating, such as Google map, to show the positioning result. To correct the position offset in the map positioning show, a position offset cancellation algorithm is proposed for accurate positioning based on triangle formula method.
