Abstract: A device and method in a radio communication system. The device includes: a location information acquisition unit for use in acquiring location information of a mobile terminal; a mobile state assessment unit for use in assessing a mobile state of the mobile terminal on the basis of the location information of the mobile terminal at different time; and, an execution unit for use in executing, on the basis of the location information of the mobile terminal and a change in the mobile state, a corresponding operation related to microcell discovery.

Abstract: A device and method in a radio communication system. The device includes: an acquisition unit for use in acquiring a signal quality of a mobile terminal relative to a source cell; an assessment unit for use in assessing the degree of change in the signal quality of the mobile terminal relative to the source cell on the basis of multiple signal qualities of the mobile terminal relative to the source cell acquired at every predetermined time interval; and, a triggering unit for use in triggering, on the basis of the degree of change in the signal quality of the mobile terminal relative to the source cell, the mobile terminal to submit a measurement result.
