A method for managing mobility of a terminal in a heterogeneous network environment is provided. According to an aspect, there is provided an operation method of a terminal receiving parameters for Coordinated Multi-point transmission/reception (CoMP) operation in a heterogeneous network environment, the operation method including, at the terminal, receiving at least one parameter among a CoMP operation mode parameter, a time information parameter regarding a time at which the CoMP operation starts, a point information parameter about points that participate in the CoMP operation, and a CoMP operation parameter, from a base station, through a layer-3 message. Therefore, it is possible to avoid an unnecessary ping-pong handover and efficiently provide service continuity.
