基于三边测量原理的一种LBS定位方法

摘要

With rapid development of the mobile Internet, the demand forh te precise positioning of the mobileterminal users becomes even more intense. Precise positioning of the mobile terminal involves many factors, theworkload is fairly large, and the error relatively great. Forh tis reason, a method which integrates the three-sidemeasurement principle and frequency-scanning mode is proposeda, nd this method, based on the descriptionparameters of multiple base-stations, optimizes the three-edgem easurement algorithm, locates the location in asmaller range, and then by using frequency-scanning mode, determines the precise location of the user. Based onthe analysis of the region where the malicious call behavior ilsocated, the traffic data are analyzed statistically, an dthe precise location of the user can thus be obtained by frequency-scanning mode.%随着移动互联网的快速发展,对移动终端用户的精确定位的需求也越来越强烈.移动终端的精确定位涉及因素较多,工作量较大且误差较大.因此,提出一种将三边测量原理和扫频相结合的方法.该方法利用多个基站的参数值,优化三边测量方法的算法,将定位区域确定在一个较小的范围内,然后再利用扫频的方式确定用户的精确位置.在分析恶意呼叫行为查找所处的区域案例中,对话务数据进行统计分析,再利用扫频方式可得到用户精确的位置,从而找到恶意呼叫的行为.
