<p>The objective is to improve the probability that, even at a time of congestion, egress processing by way of a priority terminal and egress processing of an emergency call will succeed. A mobile station (UE) as laid out in the present invention is provided with: an RA procedure execution unit (13) which, in a RA procedure for transmitting an upstream signal performed in a case of being in a DRX-state, is configured to transmit, using a contention-based method, an "RA preamble"; and an access control unit (12) which is configured so that, in response to the transmission of the "contention-based RA preamble," ACB is performed.</p> |
