PROBLEM TO BE SOLVED: To improve a connection rate when an incoming call is received and to efficiently perform an operation on the user side when the incoming call is received by measuring the receiving electric field strength of an outgoing signal transmitted from a control station by a control channel during waiting, receiving an incoming signal and generating a previous notice sound that is different in accordance with the measured receiving electric field strength and also different from a ring tone. SOLUTION: In this mobile communication terminal device 10, a receiving electric field detecting part 3 measures the receiving field strength of an outgoing signal notified from a controlling part with a control channel during waiting. A controlling part 7 decides the kind (tone) of previous notice sound to be rung from receiving electric field information on the basis of the measured receiving electric field strength and speech information showing the contents, etc. of speech notified with an incoming signal when the part 7 received the incoming signal. The decided tone is processed by a sound data processing part 6 and makes the previous notice sound to be rung. The previous notice sound rings in tone different from a ring tone showing an incoming call and has a function that shows the state of the receiving electric field strength or the contents, etc. of received speech. |
