Patent ID: 8594674

Claim:
A measurement control method for minimization of drive test (MDT) in a user equipment, the method comprising the steps of: receiving measurement frequency information for cell reselection and measurement frequencies for MDT (MDT frequencies); measuring a quality of a serving cell; performing a first quality measurement for a neighboring cell; performing a second quality measurement for the neighboring cell; and storing results of the first and second quality measurements, wherein the step of performing the first quality measurement includes performing intra-frequency measurement for the MDT for the neighboring cell when the frequency of the serving cell is included in the MDT frequencies, and performing the intra-frequency measurement for the neighboring cell only in the case where the quality of the serving cell is less than a first threshold value when the frequency of the serving cell is not included in the MDT frequencies, and the step of performing the second quality measurement includes performing intra-frequency measurement for the MDT for the neighboring cell when an inter-frequency in the measured frequency information for the cell reselection corresponds to the MDT frequencies, and performing inter-frequency measurement for the neighboring cell only in the case where the quality of the serving cell is less than a second threshold value when the inter-frequency in the measured frequency information for the cell reselection does not correspond to the MDT frequencies.
