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: According to one embodiment of the present disclosure, the method by means of which a mobility management entity (MME) determines the communication mode of a terminal in a communication system includes the steps of: receiving, from the terminal, an access request including information on the position of the terminal; transmitting a message to a home subscriber server (HSS) on the basis of the received access request; receiving, from the HSS, specific position information for setting a first mode; comparing the information on the position of the terminal with the specific position information; and determining the communication mode of the terminal according to the result of the comparison. According to the present disclosure, the frequent transmission of small amounts of data can be supported in an efficient manner.

The method of transmitting data in user equipment of a wireless communication system using a carrier aggregation technique according to an embodiment of the present invention includes setting secondary cells included in an S-TAG (Secondary-Timing Advance Group) configured of only secondary cells (SCells), deactivating a downlink timing reference cell in the S-TAG; determining whether other activated secondary cells exist besides the deactivated downlink timing reference cell in the S-TAG, and when the other activated secondary cells exist in the S-TAG, setting one of the other activated secondary cells as a new downlink timing reference cell. According to the present invention, uplink transmission speed can be increased in the user equipment and user QoS can be improved by transmitting data using one or more uplink carriers in the terminal.
