TERMINAL DEVICE, BASE STATION DEVICE, METHOD FOR CONTROLLING COMMUNICATION OF TERMINAL DEVICE, AND METHOD FOR CONTROLLING COMMUNICATION OF BASE STATION DEVICE

摘要

The present invention is provided with: a transmission/reception unit for transmitting, to a base station, a non-access stratum (NAS) message including user data and information used for notifying about the completion of user data transmission, and receiving a radio resource control (RRC) connection release message from the base station device after the information is transmitted; and a control unit that transitions to an idle state due to the reception of the RRC connection release message. The present invention thereby provides a method for establishing a PDN connection and controlling communication for performing machine-type communication to infrequently transmit a small data packet.
