1 illustrates a configuration of a conventional mobile communication terminal. Referring to the operation of the conventional mobile communication terminal as follows.

In the case of reception, the signal coming through the antenna is detected by an analog signal via a radio frequency interface (RF / IF) circuit 10, and the analog signal is transmitted by a baseband modem by a baseband analog circuit 11. 12 is converted into a recognizable digital signal. The baseband modem 12 synchronizes signals, performs error correction, and transmits data necessary for power control, frequency correction, and the like to the microprocessor 14 and the vocoder 13. The microprocessor 14 processes power control and frequency correction with data received from the baseband modem 12, receives a key input 17 for a user interface, and processes the same by a predetermined program. The LCD driver 19 Display the appropriate information. In addition, the microprocessor 14 properly controls the vocoder 13 and the memory / peripheral circuit 15, checks the unique number of the terminal from the decoded transmission data, and judges whether or not it matches with its own. Is audible to the user through the speaker 20 to notify the user that the call connection request. When the call mode is switched, the compressed voice signal received from the modem 12 is decoded by the vocoder 13, and the decoded voice signal is passed through the codec 18 to the speaker 20 or the earphone 21. Is passed to the user so that it can be recognized The user's voice is transmitted from the microphone 22 to the base station via the codec 18, the vocoder 13, the baseband modem 12, the RF / IF circuit 10, and finally the antenna. The host interface circuit 16 is an interface circuit for exchanging data when the mobile communication terminal is connected to an external host such as a PC, and the battery 23 generally uses a rechargeable battery.

2 is a diagram illustrating an embodiment of a mobile communication terminal of the present invention having a function of storing and playing an audio compressed file. Each component block of FIG. 2 performs substantially the same function as the block of the same name of FIG. 1, and here, the embodiment shown in FIG. 2 will be described centering on the operation of only the added or different blocks.

The microprocessor 29 further controls the compressed audio decoder 28 and the compressed file storage 33. The microprocessor 29 controls the compressed audio decoder 28 to play (decode) the compressed audio file stored in the compressed file storage device 33 when the music needs to be played back, thereby converting the reproduced contents into a codec. 34) and outputs to the speaker 36 or the earphone 37. In addition, the microprocessor 29 may download a compressed audio file (eg, MP3) from an external host (eg, PC) device via a host interface circuit 31, and may download other necessary data ( For example, control data) can be exchanged. The compressed audio file may be downloaded via the host interface circuit 31 or may come in through other media. For example, a compressed audio file may enter through the air as an RF signal.

The operation of the mobile communication terminal, which is an embodiment of the present invention, is different from that of the conventional terminal as follows.

The mobile communication terminal of the present invention has a music mode in addition to the normal reception standby mode and the call mode, and when the user selects the music mode when the terminal is in the reception standby mode, the mobile communication terminal of the present invention stores the compressed audio file. Play the output to the user through the speaker 36 or the earphone (37). When a call connection request comes in during the music mode, the microprocessor 29 pauses the music playback so that the current music mode is disabled and instead enables the call mode so that a call can be made as usual. do. When the call ends, the mobile communication terminal of the present invention again disables the call mode and enables the music mode to start playing the compressed audio file again from the point where it was previously interrupted.

When the music mode is not enabled when in the receive standby mode, the mobile communication terminal of the present invention operates similarly to a conventional mobile communication terminal, but operates with the compressed file decoder 28 to prevent waste of power and noise. The operation of the compressed file storage device 33 is disabled.

In addition, when the telephone call is not desired in the music mode, the call is turned off. In this case, even when a call connection request is received during the music mode, the mode transition from the music mode to the call mode does not occur. When the music mode is off, it can be implemented to automatically return to the available mode.

According to the mobile communication terminal of the present invention, the storage and reproducing function of the compressed audio file is added to the mobile communication terminal, so that the mobile terminal and the compressed audio player can be easily carried.

According to the mobile terminal of the present invention, by adding a storage and playback function of a compressed audio file to the mobile terminal at a low price, the utility value of the mobile terminal is higher than that of the existing terminal, thereby increasing the competitiveness in the mobile terminal market. .

In the foregoing description, a case of storing and playing an audio compressed file has been described. However, the present invention can be applied to a case of storing and playing an uncompressed audio file, and the method can be easily conceived from the foregoing description. .

In addition, in the above description, the case where the audio file is stored and played is described. However, when the type of data used is not audio data, for example, a system in which an image file is stored and viewed through a user display may be used. Similarly applicable and the scheme can be easily conceived from the foregoing description.

In addition, in the foregoing description, a case in which the compressed audio file is stored and played and enjoyed has been described. However, the mobile communication terminal of the present invention can be used for storing and transferring data, and even in this case, the method is easy from the foregoing description.
