Abstract

The invention provides a positioning method and device for an MR (measurement report) sampling point, and the method comprises the steps: carrying out the classification of the MR sampling point corresponding to terminal according to the MR uploaded by the terminal and a wireless transmission model corresponding to a coverage scene of a service cell; obtaining the distance between the MR samplingpoint and a base station according to the reference signal receiving power of the service cell in the MR and the wireless transmission model if the MR sampling point is an outdoor sampling point, anddetermining the position information of the MR sampling point according to the distance and the antenna AOA (angle of arrival) in the MR. The method can achieve the accurate positioning of the external MR sampling point covered by a macro-station, so as to refine the estimation of the coverage condition of a network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for locating sampling points of measurement reports. Background technique [0002] Compared with the traditional DT / CQT (drive test / dialing measurement test), by collecting the measurement report (Measurement Report, MR) of the terminal and analyzing massive data, it is possible to obtain the most real experience of network users and obtain a more comprehensive and more objective reflection. At present, most of the applications for LTE MR are limited to display and statistics. They are more inclined to monitor network performance and compare changes in network conditions before and after. This part is mainly for MR statistics of large-scale network elements, and there is no need to identify the indoor and outdoor types reported by MR. ; Some methods for MR data application to user positioning, etc., are to directly apply the MR data collected b...
