Abstract

The embodiment of the invention provides a positioning method and device. The method comprises the steps that first terminal signal fingerprint information measured at the first moment and reported by a terminal is obtained; a target grid is determined from a positioning database according to the first terminal signal fingerprint information; the position information of the target grid is determined as the position information of the terminal. According to the technical scheme, when the target grid corresponding to the terminal is determined, the relation between the characteristic relevancy of the target grid and the characteristic relevancy of an adjacent grid is taken into consideration. Thus, it can be avoided that due to signal fluctuation and other reasons, the positioning accuracy is affected by a strange grid, and the positioning precision is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and more specifically, to a positioning method and device. Background technique [0002] With the rapid development of communication technology and its applications, communication-based positioning technology has received more and more attention. Terminal location information is the basis of many innovative value-added services and applications. For example, positioning technology can be applied to wireless network refinement optimization and problem analysis, or to security, targeted advertising push, navigation and other fields. [0003] How to accurately determine the location information of the terminal is an urgent problem to be solved in this field. The method of determining the location information of the terminal in the prior art is to select the fingerprint information of the grid with the best correlation with the signal fingerprint information ...
