Abstract:
1. A method for performing measurement by a User Equipment (UE) in a mobile communication system including the UE having a Discontinuous Reception (DRX) mode for discontinuously receiving data and a continuous reception mode for continuously receiving data, a serving cell where the UE is located, and a neighboring cell located near the serving cell, the method comprising: measuring signal strength of the serving cell according to a period of the DRX mode; continuously performing the signal strength measurement on the serving cell and the neighboring cell, when the measured signal strength of the serving cell is less than or equal to a particular threshold; starting a timer for transmitting a measurement result to the serving cell, when the measured signal strength of the neighboring cell is greater than or equal to the measured signal strength of the serving cell; and transmitting the measurement report to the serving cell, when the signal strength of the neighboring cell is greater than or equal to the signal strength of the serving cell until the timer expires.
