Abstract

A method for indicating a direction of a destination in a mobile communication terminal includes: receiving network identification information from a mobile communication network that is currently accessed; reading current location and declination information corresponding to the network identification information from a mobile communication network information table; obtaining true north information by using the declination information to correct magnetic north information of a current location measured with a geomagnetic sensor; obtaining direction information of the destination from the current location information on the basis of the true north information; and displaying the direction information of the destination.
