On the other hand, the user uses the keypad 13 of the mobile communication terminal to select a specific menu while making a call connection using the mobile communication terminal or receiving an ARS service through the ARS server, or a number (0 to 9) or When the special characters (#, *) are pressed, the main control unit (MSM) 12 recognizes this as a key button input for call connection or command input to activate the DTMF tone generator 11.

Then, the DTMF tone generator 11 generates a DTMF tone assigned to the corresponding key button according to the key button input, and transmits the DTMF tone to the RF transmitter 10, and the DTMF tone generator 10 transmits the DTMF tone to RF. By converting the signal and transmitting the signal to the exchange or the ARS server through the wireless network, a call connection or a service according to the selected menu is provided from the ARS server.

At this time, when the mobile communication terminal receives the ARS service from the ARS server through the wireless network, according to the assumption of the present invention, the ARS server needs DTMF tones for selecting voice information guiding a specific menu and a menu in progress. Sends an RF signal containing information on the mobile communication terminal.

Then, the RF receiver 14 of the mobile communication terminal receives an RF signal including voice information and DTMF tones, extracts the DTMF tones, transmits the DTMF tones to the DTMF tone determiner 15, and the DTMF tone determiner 15. Translates the extracted DTMF tones into digital signals and stores them in the DTMF tone buffer unit 16.

Here, when the DTMF tones stored in the DTMF tone buffer unit 16 are pressed later by pressing a menu selection key to select a menu currently in progress, a key button input signal is input to control of the main controller 12. Accordingly, by transmitting to the ARS server through the RF transmitter 10, a DTMF tone is generated through the keypad unit 13 of the mobile communication terminal to generate the same effect as that of the ARS server. To select the menu.

The DTMF tone buffer unit 16 updates the stored DTMF tones every time it is input from the DTMF tone determination unit 15, so that the DTMF tone buffer unit 16 is always required to select a menu currently in progress. Ensure that only DTMF tones are stored.

In addition, the menu selection key for selecting the menu currently in progress, except for the number (0-9) or the special character (#, *) key button previously assigned to generate DTMF tones, the keypad unit 13 You can add a separate key button to the setting or use an existing function key button.

Meanwhile, when an embodiment of the DTMF tone transmission method of the present invention communication terminal is applied to a wireless network, as shown in FIG. 2, after connecting to an ARS service through a wired or wireless network, a specific menu is transmitted from the ARS server in the communication terminal. Receiving RF signals including voice information for guiding information and information on DTMF tones necessary for selecting a menu in progress (S20 and S21); Extracting and storing a DTMF tone from the received RF signal (S22); Transmitting a stored DTMF tone to an ARS server through a wired / wireless network when a menu selection key is selected and a key button input signal is input (S23, S24); If the key button input signal of the menu selection key is not input, the DTMF tone of the key button to which the DTMF tone is assigned is transmitted from the keypad unit 13 to the ARS server, and the key button is re-entered for the key button to which the DTMF tone is not assigned. It consists of the steps (S25-S27) which request | requires.

When the user connects to the ARS server to receive the ARS service through the wired / wireless network using the communication terminal (S20), the communication terminal needs to select voice information and a menu currently in progress from the ARS server. Receives a signal containing information on the DTMF tone, that is, DTMF signal, in this case, when connected to the wireless network receives the RF signal through the RF receiver 14 (S21), if connected to a wired network the RF receiver ( 14) Instead of connecting to a wired network through an interface unit (not shown) to receive a DTMF signal.

Then, the DTMF tone determination unit 15 and the DTMF tone buffer unit 16 extract and store DTMF tones from the received RF signal (S22).

At this time, according to the assumption of the present invention, the ARS server transmits a voice signal including voice information for guiding a specific menu to the communication terminal as shown in FIG. 3 and provides information about DTMF tones required for selecting a menu in progress. Will be sent together.

For example, in the case of an ARS server that delivers traffic information, the ARS server transmits a voice signal such as "Gyeongbu Line No. 1", "Jungbu Line No. 2" and "Youngdong Line No. 3" as voice information to the user. The DTMF tone required for selecting the voice information menu provided by the signal is synchronized and transmitted, and the user selects the menu selection key during the time when each voice signal is received, that is, during the time of listening to the voice information reproduced by the voice signal.
