1. A portable terminal comprising:
- a memory unit configured to store an Earth'"'"'s magnetic field component corresponding to a predetermined zone for controlling a function of the portable terminal, and information of function to be executed at the predetermined zone; and
a controller coupled to the memory unit, the controller configured to;
control a sensor to acquire an Earth'"'"'s magnetic field component corresponding to a current location of the portable terminal,determine whether the portable terminal is located within the predetermined zone by comparing the acquired Earth'"'"'s magnetic field component and the stored Earth'"'"'s magnetic field component, andif the portable terminal is located within the predetermined zone, execute a function corresponding to the predetermined zone in which the portable terminal is located.

Abstract
An apparatus and method for recognizing an indoor zone in which a user is located by using an Earth'"'"'s magnetic field that is generated naturally instead of the conventional method of combining a magnetic field generator and a magnetic field sensor. The apparatus includes a zone evaluator configured to primarily recognize a location of the portable terminal by using first and second components of an Earth'"'"'s magnetic field and to finally recognize the location of the portable terminal by using first and second images.

6. A method of recognizing a zone of a portable terminal, the method comprising:
-
storing an Earth'"'"'s magnetic field component corresponding to a predetermined zone for controlling a function of the portable terminal, and information of function to be executed at the predetermined zone; acquiring an Earth'"'"'s magnetic field component corresponding to a current location of the portable terminal; determining whether the portable terminal is located within the predetermined zone by comparing the acquired Earth'"'"'s magnetic field component and the stored Earth'"'"'s magnetic field component; and if the portable terminal is located within the predetermined zone, executing a function corresponding to the predetermined zone specific location in which the portable terminal is located. - View Dependent Claims (7, 8, 9, 10)
