Abstract: The present invention defines an efficient method for (re)selecting a cell according to a speed of a terminal in a HetNet where cells having various regions such as macro cells, pico cells and femto cells are arranged in the same frequency band in a mobile communication system. A cell selection control method of a terminal in a mobile communication system, according to an embodiment of the present invention, comprises a step of receiving, from a base station, cell list information for not allowing a terminal moving at a high speed to select a cell and a step of setting the terminal so that cells included in the cell list information are considered or not considered to be targets of selection or reselection when the terminal moves at the high speed. According to the present invention, in a network consisting of various types of cells using the same frequency band, the terminal can determine whether to select or reselect a cell according to the speed of the terminal. That is, the terminal moving at the high speed does not select or reselect a frequent service cell, thereby efficiently performing the cell selection or reselection. Further, power consumption of the terminal can be reduced.
