When the control block outputs music data 1 to melody generation block, the melody generation block generates the calling melody signal based on music data 1, and transmits it to the other party of the telephone call via modem, sending and receiving block and antenna. Moreover, the control block always observes the control channel specified by the base station while waiting. When detecting the arrival of a call and “4” of the calling melody specification data, the control block judges for caller information transmitted at the same time whether to be registered in telephone/E-mail memory.
