说明：  针对大型建筑物复杂环境室内定位的特殊性，为了克服移动终端采用WLAN或无 线传感器网络单独定位精度不高的局限性，实现移动终端精确定位导航,提出了根据终端位 置环境同时搜索WLAN和无线传感器网络，采用改进后的网络融合定位算法，可以为用户 提供高精度、高概率和高保密性的定位业务。
(For large buildings in the complex environment of indoor positioning particularity, in order to overcome the mobile terminal using WLAN or wireless sensor network alone is not high positioning accuracy limitations, to achieve precise positioning and navigation mobile terminal is proposed to simultaneously search and WLAN wireless sensor environment based on terminal location network, using the improved network fusion location algorithm can provide users with high-precision, high-probability and high-security location services.)
