Provided are user equipment capable of, even when having made a transition from LTE to 3G by SRVCC while receiving announcement sound from the network side in response to a call request to a terminating terminal, continuing the output of the announcement sound, and a mobile communication method. UE (100A) executes continuation processing (SRVCC) of a 3G sound communication service if the connection destination of the user equipment makes a transition from LTE to 3G. Further, the UE (100A) receives announcement sound via LTE or 3G, and outputs the announcement sound after making a request to call a party at the other end and before starting to call the party. The UE (100A) outputs the announcement sound even after making the transition to 3G if the continuation processing of the sound communication service is executed during a period when the announcement sound is being outputted.
