1. A device for updating location information of an idle state terminal in a communication system supporting an idle state, the device comprising:
- a terminal location notifying unit for obtaining location information of the terminal based on the terminal and a base station covering the terminal;
a paging timer registering unit for calculating an expectation time for updating the location information based on a speed of the terminal and the location information of the terminal, registering the expectation time to a paging timer, and operating the paging timer when a state of the terminal is changed from an active state to the idle state; and
a location information update unit for updating the location information when the paging timer expires.

Abstract
A device and method for updating location information of an idle state terminal in a communication system supporting an idle state of a terminal are provided. In the method, an expectation time for updating the location information is calculated according to a moving speed of the terminal, when a state of the terminal is changed to an active state to the idle state, the calculated expectation time is registered to a paging timer, and the paging timer is operated, the location information of the terminal is updated when the paging timer expires.
