METHOD AND APPARATUS FOR REQUESTING LOCATION UPDATE OF TERMINAL IN IDLE MODE, METHOD FOR DETERMINING ENTRY TO IDLE MODE OF TERMINAL, AND METHOD AND APPARATUS FOR TRIGGERING LOCATION UPDATE OF TERMINAL IN IDLE MODE

摘要

PURPOSE: A method and an apparatus for requesting location update of a terminal in idle mode, a method for determining entry to idle mode of the terminal, and a method and an apparatus for triggering location update of the terminal in idle mode are provided to prevent resource waste of a base station and power consumption of the terminal. CONSTITUTION: If a terminal enters idle mode, a sensing unit(110) senses whether the terminal moves. If the terminal continuously moves during fixed time, a determining unit(120) determines whether a base station about the terminal is changed. If the base station about the terminal is changed. A location update requesting unit(130) requests to update a location. A location update procedure is performed.
