Abstract
In one embodiment, a mobility management device MME selects a Logged MDT implementation terminal that should implement a measurement process by Logged MDT, from among a plurality of radio terminals UE in a mobile communication systemcompatible with the Logged MDT defined in the 3GPP standards. The mobility management device MME stores camping history information in which information indicating a TA on which a radio terminal has camped is associated with information indicating a time period during which the radio terminal has camped on the TA, for each of the plurality of radio terminals UE. Then, the mobility management device MME selects, as the Logged MDT implementation terminal, a radio terminal having a relatively long camping time period corresponding to a measurement target area on which the measurement process is to be performed, from among the plurality of radio terminals UE.
