METHOD FOR PROVIDING SERVICE OF ESTIMATING LOCATION BASED ON CHANGE OF STATE OF USER TERMINAL AND THE USER TERMINAL THEREOF

摘要

According to an embodiment, the magnetic field characteristics of the sample region may be determined by using magnetic field values collected from at least some of the target regions for determining the location of the user based on the earth magnetic field, and based on the magnetic field characteristics of the sample region. A method and apparatus for generating a magnetic field map for building a database may be provided by using the collected magnetic field values of the target area according to a sampling interval for the target area determined as.
