Abstract
A mobile station and a mobile communication method are provided, which are capable of continuing output of an announcement sound even if a transition is made from LTE to 3G by SRVCC when the announcement sound is being received from a network side in response to a call request to a call-terminating terminal. A UEA executes continuation processing (SRVCC) of a 3G voice communication service if the mobile station makes a transition of a connection destination from LTE to 3G. Further, the UEA receives the announcement sound via LTE or 3G, and outputs the announcement sound after requesting alerting of the other party and before starting the alerting of the other party. The UEA outputs the announcement sound even after making a transition to 3G if the continuation processing of the voice communication service is executed during a period when the announcement sound is being outputted.
