Abstract: The present invention pertains to a method and device for preserving mobility information in terminal state transition and effectively re-accessing in a heterogeneous cell network in a mobile communication system. A method for estimating a mobility state of a terminal in a mobile communication system according to one embodiment of the present invention may comprise the steps of: receiving, by the terminal, system information from a serving cell during an idle state; calculating mobility state information by using the received system information; storing the mobility state information; and transmitting the mobility state information to a base station when the terminal is connected to the base station. According to one embodiment of the present invention, when an idle state of a terminal is changed to a connection state in a mobile communication system, a mobility state of the terminal can be more effectively estimated.

Abstract: The present invention relates to a method and apparatus for activating carriers in a mobile communication system, and includes determining, when an instruction message for aggregating multiple carriers is received, a bit position per carrier according to an identifier per carrier in the instruction message; checking, when a carrier state message including a state bitmap indicating state per carrier, the state per carrier according to the bit position per carrier in the state bitmap; and activating/deactivating the carriers according to the per-carrier states. According to the present invention, it is possible to minimize signaling overhead caused by carrier activation and deactivation.
