摘要

PURPOSE: An ms-assisted and ms-based TDOA and TDOA correction for each square form network positioning method and system in the wibro, and media that can record computer program sources for method the same are provided to allow a user to easily measure TDOA. CONSTITUTION: A mobile terminal(30) receives a positioning request command. The mobile terminal collects the radio wave characteristic information of a current position. A positioning algorithm calculates the coordinate through an TDOA mode. It is determined whether a compensation value is applied according to the existence and nonexistence of a TDOA correction database. A positioning result is determined. The difference between a calculation value and the position of a real terminal is stored at each lattice. A base station information database is generated by extracting the base station information from the TDOA correction databases.
