Abstract
A radio terminal according to one embodiment comprises: a controller configured to detect a radio problem in communication with a base station in an RRC connected state and attempt a recovery from the radio problem; and a transmitter configured to transmit, to the base station, a polling signal for confirming whether or not the base station considers an RRC state of the radio terminal as the RRC connected state in response to the successful recovery. The controller maintains the RRC connected state in response to reception, from the base station, of a response signal to the polling signal.
