Provided are a system and method that enable identification of a cause of failure in radio coverage detected by a radio terminal (UE) on a radio network side, and that enable determination and execution of a countermeasure in response to a result of the identification. The radio terminal (UE), which acquires measurement instruction information from a radio station, measures and records in accordance with the measurement instruction information, and reports to the radio station. The radio terminal, in case of a first condition on selection or detection of a first cell (allowed cell) in which the radio terminal is allowed to be served for a predetermined service being satisfied, and a second condition on measurement or logging being satisfied, logs information on a second cell (not allowed cell) in which the radio terminal is not allowed to be served for the predetermined service. |
