1. A radio terminal used in a mobile communication system, comprising:
- a receiver; and
a controller configured to perform controls related to an extended discontinuous reception (DRX) operation for intermittently monitoring a downlink control channel based on a comparison result of a value related to a moving speed of the radio terminal and a threshold value when the extended DRX operation is set from a network, whereinthe controller is further configured to perform measurement on downlink reference signals based on measurement setting information received from the network,the measurement setting information includes a report condition indicating a condition under which a measurement report is transmitted to the network, andthe controller is further configured to change the report condition according to the value related to the moving speed of the radio terminal.

17. A radio terminal used in a mobile communication system, comprising:
-
a receiver; and a controller configured to perform controls related to an extended discontinuous reception (DRX) operation for intermittently monitoring a downlink control channel based on a comparison result of a value related to a moving speed of the radio terminal and a threshold value when the extended DRX operation is set from a network, wherein the controller is configured to stop the extended DRX operation when the value related to the moving speed of the radio terminal exceeds the threshold value under a circumstance in which the network is in an inter-cell asynchronous state, and the controller is further configured to acquire information indicating that the network is in the inter-cell asynchronous state from the network.
