The present invention relates to a voice message service of a mobile communication terminal, and more particularly, to a method of providing a voice message service using a function key or a menu provided in the mobile communication terminal.

As mobile communication terminals spread rapidly, callers want more convenient and useful services. In general, the mobile communication terminal has a function of providing additional services to the caller in addition to the telephone call service. Additional services available to callers include cell phone calls, text messaging services, voice messaging services, and services over the Internet. This additional service is available when the caller applies to the service provider.

The method of using a text message service through a mobile communication terminal is inconvenient because the input speed is slow and cumbersome when sending a message of a somewhat long sentence or a message mixed with Korean and English. On the other hand, the voice message service is suitable for sending a lot of information in a short time.

A voice message service method using a conventional mobile communication terminal is as follows. The input unit 110 is composed of a plurality of buttons and receives the identification number of the receiving mobile communication terminal from the sender (S210). The call connection unit 120 attempts to connect a call with the receiving mobile communication terminal (S220). At this time, if the other party is busy or missed or the receiving mobile terminal is turned off, the voice message recording announcement comes out. The sender can leave a voice message by choice. The caller selects a voice message recording button (S230), and records a voice message through the microphone 130 (S240). The transmitter / receiver 140 transmits the recorded voice to a VMS (Voice Mail System) of the mobile communication company (S250). When the receiver is notified that the voice message has arrived at the receiving mobile communication terminal (S260), the receiver accesses the VMS of the mobile communication company and listens to the received voice message (S270). The controller 150 outputs a control signal for controlling the overall operation of each component.

However, in the related art, the caller can use the voice message service only when the receiver's mobile communication terminal is turned off, the receiver is absent, or busy. That is, if the caller attempts to set up a call to the receiver and the call is not connected, the voice message may be left by the caller's selection.

Such a voice message service is inconvenient, even if the caller does not want to make a phone call with the receiver or only wants to leave a voice message directly to the receiver.

The present invention provides a mobile communication terminal and a voice message service method capable of a voice message service capable of leaving a voice message on a mobile communication terminal of a receiver according to a caller's choice regardless of the state of the mobile communication terminal of the receiver.
