Abstract: The present invention relates to a method and an apparatus for controlling mobility for a cell having a small cell service area in a mobile communication system. A method for controlling mobility of a terminal in a mobile communication system, according to one embodiment of the present invention, can comprise the steps of: performing, by the terminal, a measurement operation; transmitting a measurement result to a base station; determining whether or not a target cell for handover is a cell for which handover is allowed; and skipping the handover if the target cell for handover is the cell for which handover is not allowed. According to one embodiment of the present invention, when the small cells are arranged sparsely or in the form of a cluster within a service area of a macro cell, the possibility of a handover failure can be reduced, and if a radio link failure occurs when handover is omitted, re-connection can be performed quickly by the terminal.
