Positioning method and device based on measurement report

D The invention discloses a positioning method and device based on a measurement report, and the method comprises the following steps: S1, obtaining a plurality of MR samples, enabling collected MR sample data to contain the position information of a sampling point, and marking whether the environment is indoor or outdoor; and S2, building a decision tree through a C4.5 model by using the collected MR sample data with the indoor or outdoor mark. The invention relates to the technical field of mobile communication. According to the positioning method and device based on the measurement report, the accuracy of positioning the position of the terminal through MR data is improved, whether the environment where the terminal is located is indoor or outdoor is distinguished through the decision tree, and sampling points in different environments are positioned by using different algorithms, so that higher positioning accuracy and efficiency are obtained, the coverage condition of the cell can be reflected, and the c
