POSITIONING METHOD, DEVICE, POSITIONING CENTER, TERMINAL AND COMPUTER STORAGE MEDIUM

The present invention provides a positioning method, device, positioning center, terminal and computer storage medium. The method includes: when receiving a positioning request message requesting to position a first terminal, calculating an original position range of the first terminal according to first correspondence relationship between a pre-stored terminal identifier and base station information of a base station in which the terminal is currently located, herein the positioning request message carries a first terminal identifier of the first terminal; acquiring second position information of at least three second terminals within a target position range, herein the positioning accuracy of the second terminals is higher than that of the first terminal, and the target position range is determined according to the original position range of the first terminal and a preset regional radius; acquiring measurement result of distances measured by the first terminal from the second terminals according to the first terminal identifier; and calculating first position information of the first terminal according to second position information and measurement result.
