A radio terminal (2) controls state transitions of the radio terminal (2) among first to third RRC states. In addition, if the radio terminal (2) is in the second RRC state, if a current cell that the radio terminal (2) has camped on is different from a first cell in which a state transition from the first RRC state to the second RRC state was performed, and if the current cell satisfies a predetermined condition, the radio terminal (2) allows the radio terminal (2) to transmit data to be transmitted in the current cell by a first transmission procedure in which the radio terminal (2) transmits uplink data before entering the first RRC state.
