Abstract
An apparatus for estimating location of a location request terminal receives a location request signal including first wireless communication infrastructure measurement information through a first wireless communication infrastructure of first coverage range and a second wireless communication infrastructure measurement information through a second wireless communication infrastructure of second coverage range greater than the first coverage range, estimates different types of second wireless communication infrastructure measurement information measured at the same location as the location request terminal, generates extended second wireless communication infrastructure measurement information by combining the second wireless communication infrastructure measurement information and the estimated second wireless communication infrastructure measurement information, and determines location of the location request terminal through comparison between a location DB storing the measurement information collected through the first wireless communication infrastructure and the second wireless communication infrastructure in correspondence with each grid location and the extended second wireless communication infrastructure measurement information.
