LTE to 3G by SRVCC when the announcement sound is being received from a network sidein response to a call request to a call-terminating terminal. A UE 100A executes

continuation processing (SRVCC) of a 3G voice communication service if the mobile stationmakes a transition of a connection destination from LTE to 3G.
