Measurement method for generating cell coverage map and device for the same
a measurement method for minimization of drive test (MDT) comprises steps of: receiving measured frequency information for cell reselection and measured frequencies for MDT; measuring a quality of a serving cell; performing a first quality measurement on a neighboring cell; performing a second quality measurement on the neighboring cell; and storing results of the first and second quality measurements, wherein the step of performing the first quality measurement includes performing an intra-frequency measurement for the MDT on the neighbor cell when the frequency of the serving cell is included in the MDT frequencies, and performing the intra- frequency measurement for the neighbor cell only in the event where the quality of the serving cell in a first threshold value or less when the frequency of the serving cell is not included in the MDT frequencies, and the step of performing a second quality measurement includes performing an intra- frequency measurement for the MDT on the neighbor cell when an inter-frequency in the measured frequency information for the cell reselection is the MDT measurement frequency, and performing an intra-frequency measurement on the neighbor cell only in a case where the quality of the serving cell is a second threshold value or less when the inter-frequency in the measured frequency information for the cell reselection is not the MDT measurement frequency.
