The present invention relates to a mobile communication terminal, and more particularly, to an application technology field that enables a user to have fun utilizing a sound source reproduction function of a mobile communication terminal.

As is well known, currently available mobile communication terminals are provided with a sound source playback function. The ringer reproducing unit provided in the mobile communication terminal reproduces the sound source data and outputs it through the speaker. The ringtone player may be implemented as a separate chip implemented to play sound source data such as an MP3 file or a MIDI file. The performance of the ringtone reproducing unit is gradually improving, and it is possible to play 16 chords, 32 chords, and 40 chords.

When a mobile communication terminal is manufactured, various sound source data are basically embedded. Such sound source data is typically utilized as an incoming ring tone to notify the reception of a call or the arrival of a message.

The demand for users to have their own unique ringtones is increasing, and as a way to create various additional services, a ringtone download service using an automatic response system (ARS) is gaining popularity.

As wireless internet technology using a mobile communication terminal has been improved, it is possible to transmit data stored in an individual mobile communication terminal to a predetermined site or to transmit data from a site to the mobile communication terminal. In addition, as data transmission technology using a serial port or a near-infrared communication port provided in a mobile communication terminal has become popular, data exchange between a general terminal such as a personal computer and a mobile communication terminal is possible.
