1. A User Equipment (UE) comprising:
transmission and reception circuitry; and
controlling circuitry, wherein:
the transmission and reception circuitry is configured to receive, from a network, in a registration accept message or a configuration update command message, first information which is applied to a first Public Land Mobile Network (PLMN) and a first Radio Access Technology (RAT),
the first information is information indicating a range used for setting a wait timer that the UE starts when the UE returns in coverage after being out of coverage due to discontinuous coverage,
in a case that the UE returns in coverage after being out of coverage due to the discontinuous coverage, the controlling circuitry is configured to start the wait timer based on the first information, and
in a case that an emergency call is made,
the controlling circuitry is configured to stop the wait timer that is running, and
the transmission and reception circuitry is configured to transmit a Non Access Stratum (NAS) message.
