Claim Text:
1. An apparatus for correcting location measurement information of mobile communication terminals, comprising: a handling hardware processor configured to automatically collect downlink location measurement information sampled without user intervention by anonymous mobile communication terminals at unknown locations with respect to base stations to prepare measurement correction map generation, and environment information containing locations of the base stations and arrangements of roads or buildings from a network; a database configured to store the location measurement information from the anonymous mobile communication terminals based on an internally-generated aliased index, and configured to store the environment information; an analysis hardware processor configured to analyze the location measurement information and the environment information to generate measurement correction maps to prepare correction information service; a measurement correction map database configured to store the measurement correction maps; and a service hardware processor configured to refer to the stored measurement correction maps and to provide a corrected location measurement service, or a measurement correction-value broadcast service to mobile communication terminals which request location services regardless of providing their previous downlink location measurements information to the handler.
