    • A method and apparatus for determining accuracy information of location information. The method includes receiving Global Positioning System (GPS) location information of a user terminal from a GPS, determining whether the user terminal enters into a GPS shadow area, checking terminal movement information including a moving speed and a moving direction of the user terminal, when the user terminal enters into the GPS shadow area, estimating location information of the user terminal based on the terminal movement information, checking auxiliary location information including a moving state of the user terminal, error information of a terrestrial magnetism sensor, and the moving speed of the user terminal, and determining the accuracy information based on an accumulated location error of the estimated location information, based on the auxiliary location information.
    • 一种用于确定位置信息的精度信息的方法和装置。 该方法包括从GPS接收用户终端的全球定位系统(GPS)位置信息,确定用户终端是否进入GPS影像区域,检查包括用户终端的移动速度和移动方向的终端移动信息,当 用户终端进入GPS阴影区域,基于终端移动信息估计用户终端的位置信息,检查包括用户终端的移动状态的辅助位置信息,地磁传感器的错误信息,以及移动速度 用户终端,并且基于所述辅助位置信息,基于估计位置信息的累积位置误差来确定准确性信息。
