1. A communication control method, comprising:
- a step A of notifying, by a user terminal, when the user terminal is in a connected state, a network apparatus of RAT information on a radio access technology (RAT) on which the user terminal supports an MDT measurement;
a step B of setting to the user terminal, by the network apparatus, a PLMN (public land mobile network) list indicating a public land mobile network that permits the MDT measurement, on the basis of the RAT information;
a step D of transmitting to a base station, by the user terminal, notification information indicating that the user terminal holds a plurality of measurement results for different RATs and identification information indicating an RAT corresponding to each of the plurality of measurement results;
a step F of transmitting to the base station, by the user terminal, a measurement result report;
a step G of determining, by the base station, whether the measurement result report received from the user terminal includes the plurality of measurement results corresponding to a plurality of RATs; and
a step H of transmitting to the user terminal, by the base station, control information indicating whether or not to permit deletion of a measurement result corresponding to one of the plurality of RATs, in response to the determination that the measurement result report received from the user terminal includes the plurality of measurement results corresponding to the plurality of RATs.

7. A base station, comprising:
-
a receiver configured to receive from a user terminal, notification information indicating that the user terminal holds a plurality of measurement results for different RATs and identification information indicating an RAT corresponding to each of the plurality of measurement results, wherein the receiver is further configured to receive a measurement result report from the user terminal, and a controller configured to determine whether the measurement result report received from the user terminal includes the plurality of measurement results corresponding to a plurality of RATs, and transmit to the user terminal, control information indicating whether or not to permit deletion of a measurement result corresponding to one of the plurality of RATs, in response to the determination that the measurement result report received from the user terminal includes the plurality of measurement results corresponding to the plurality of RATs.
