1. A communication control method used in a user equipment that performs a predetermined data transmission in which uplink user data is transmitted during a random access procedure, the method comprising:
transmitting, by the user equipment in a predetermined RRC state in which an RRC connection is suspended, during the random access procedure, a first message for the predetermined data transmission, to a base station; and
after transmitting the first message, receiving, by the user equipment, a second message along with downlink user data from the base station, the second message for maintaining the user equipment in the predetermined RRC state.
