INTER-FREQUENCY/INTER-RAT CELL RESELECTION METHOD AND APPARATUS OF UE IN LTE MOBILE COMMUNICATION SYSTEM

摘要

An inter-system cell selection method of a terminal in a mobile communication system is provided. The present disclosure may be embodied in the 3rd Generation Partnership Program (3GPP) Long Term Evolution (LTE)/LTE-Advance (LTE-A) system as a mobile communication system. The cell reselection method of a terminal operating in idle mode includes receiving system information broadcast within a cell in performing measurement for cell reselection to a neighbor cell, determining whether the system information includes a movement condition threshold value, configuring at least one of a cell selection receive level and a cell selection quality as comparison criteria for cell reselection according to the determination result, and performing the cell reselection according to the comparison result.
