Abstract: The present invention discloses a method, which mainly includes: calculating location information of a estimated point by using a set algorithm according to location information of an original point; and calculating a wireless eigenvalue of the estimated point according to a wireless eigenvalue of the original point obtained by measuring; when a wireless eigenvalue reported by a terminal is received, positioning a location of the terminal according to the wireless eigenvalue of the original point and the wireless eigenvalue of the estimated point. In this way, in a mathematical model manner, location information and a wireless eigenvalue of an unmeasured raster point are fitted, with no need to increase an additional measurement workload, thereby saving a resource. In addition, a division granularity of raster measurement may be changed according to an actual requirement, thereby improving accuracy of terminal positioning.
Abstract translation: 本发明公开了一种方法，其主要包括：根据原点的位置信息，使用设定算法计算估计点的位置信息; 以及根据通过测量获得的原始点的无线特征值来计算估计点的无线特征值; 当接收到由终端报告的无线特征值时，根据原始点的无线特征值和估计点的无线特征值来定位终端的位置。 以这种方式，以数学模型的方式，拟合未测量的光栅点的位置信息和无线特征值，而不需要增加额外的测量工作量，从而节省资源。 此外，可以根据实际需要改变光栅测量的分割粒度，从而提高终端定位的精度。
