A network apparatus that instructs a radio station to let a radio terminal to obtain measurement information in an idle state, and report the obtained measurement information in an active state, comprising:

• notification means configured to notify a radio station managing a first cell of a first radio access technology where the radio terminal stays of the first configuration information related to obtainment of the measurement information in the first cell by the radio terminal;
• and
• instruction means configured to instruct the radio station to let the radio terminal to report information related to the measurement information obtained in the first cell after the radio terminal moves to a second cell of a second radio access technology different from the first radio access technology.
