Abstract: The present invention relates to a method for managing cell informations received from neighbor cells for MDT (Minimization of Drive Test) in the 3GPP system and terminal for performing the method, the terminal including a transceiver which receives cell informations transmitted by at least one neighbor base station; a controller which checks at least one cell information for generating location prediction information to check current location of the terminal among the cell informations received by the transceiver; and a memory which stores the at least one cell information for generating the location prediction information as Minimization of Drive Test (MDT) measurement sample for reporting radio environment under the control of the controller. The terminal is capable of logging the neighbor cell measurement information efficiently depending on whether the terminal logs RF fingerprint information in the idle mode.
