Embodiments of the present invention provide a terminal positioning method and device. The method includes: acquiring original measurement report data of the terminal to be tested, wherein the original measurement report data includes trajectory data of at least two first trajectory points; according to the trajectory data, filtering from the first trajectory points The second trajectory point that meets the preset reliability probability requirements, and determine the movement trend direction of the terminal according to the trajectory data of the second trajectory point; according to the movement trend direction and the preset trajectory fitting function, sequentially Perform trajectory correction on the non-second trajectory points in the original measurement report data to obtain a corrected reference point; select a point within a preset distance range from the reference point and in the direction of the moving trend as the non-second trajectory point The target track point for the second track point. The embodiment of the present invention solves the problems of large errors in positioning results of a positioning algorithm based on MR data, and out-of-sequence and confusion of single-user positioning tracks.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular, to a terminal positioning method and device. Background technique [0002] With the development of mobile communication technology, Long Term Evolution (LTE), a general mobile communication technology, has occupied a large user market share due to its superior characteristics. A Time Division Long Term Evolution (TD-LTE) system is a common system in LTE. Measurement is one of the important functions of the TD-LTE system. The system needs to use the measurement data analysis results to trigger events such as cell selection, reselection, and handover. Statistical analysis of a large amount of measurement data can also be used to find problems in the network. Compared with road test data, measurement data analysis results have the advantages of more comprehensive, complete, and direct reflection of network performance. [0003] The triggering ...
