Reference is now made to Fig. 2, which is a control flow diagram for storing a telephone number for connecting to an answering machine and an dial key code for using a particular service thereof according to an embodiment of the present invention.

First, in step 200, the control unit 100 determines whether the call connected to the answering service is terminated. If the call is terminated, the control unit 100 proceeds to step 205. A message asking whether to save the column is displayed on the display unit. Here, the telephone number to which the call was connected refers to a telephone number pressed to connect to the answering machine, and the dial key code string inputted during the call corresponds to a key pressed by the user to use any specific service of the answering machine. It may be referred to as key input data. If there is a selection from the user to store the input dial key code string during a call, the control unit 100 proceeds to step 210 and displays a guide message according to the storage method through the display unit. The storage method is divided into a general phone number storage method and a specific service phone number storage method. After displaying the storage method guide message as described above, if there is a selection from the user among the storage methods, the controller 100 proceeds to step 215 to determine whether the selected method is a specific service telephone number storage method. . If it is determined that the specific service phone number is not stored, the process proceeds to step 220 and performs the corresponding function according to the normal phone number storage. On the contrary, when the storage method selected by the user is a specific service telephone number storage method, the control unit 100 proceeds to step 225 and the dial key code string input for using the telephone number of the answering service connected to the call and the specific service thereof. To be temporarily stored in the memory 130. The control unit 100 then proceeds to step 230 and requests the user to enter a description with a user-defined name for the telephone number of the answering machine service and the dial key code string for using the specific service thereof. When a description is input from the user in response to the request, the control unit 100 determines whether the description of the telephone number of the answering service and the description of the dial key code string for using the specific service is completed in step 235. . When the determination result input is completed, the control unit 100 proceeds to step 240 to store the telephone number of the answering service and the dial key code string for using the specific service in the memory 130 including the description. . After such a process is performed, the controller 100 ends the process of storing a telephone number for connecting to an answering machine and a dial key code string for using a specific service thereof.

Now as a first embodiment a mobile telephone terminal for using a specific service of an answering service with a telephone number for connecting to the stored answering machine according to an embodiment of the present invention and a dial key code string for using the specific service thereof. 3 to 5 are flowcharts illustrating an example of a screen for connecting an answering machine according to an embodiment of the present invention.

3 to 5, if there is a key input corresponding to selection of the main menu of the key input unit 120 from the user, the controller 100 displays a main menu screen as shown in FIG. 5 (a). . Accordingly, after checking the main menu on the main menu screen, the user may select a list such as "5. Answering service connection" to connect to the answering service.

First, in step 300, the control unit 200 checks whether the user selects a telephone number menu for connecting to an answering service such as "5. answering service connection". If there is a telephone number menu selection for connecting to the answering service from the user, the controller 100 proceeds to step 310 to display the main screen of the answering service connection through the display 110. Here, the main screen of the answering machine service connection, as shown in FIG. 5 (b), displays a list of telephone numbers for connecting to the answering machine service under the control of the controller 100.

Referring to Figure 5 (b), the main screen of the answering service connection is displayed a list of telephone numbers for the answering service connection including a description entered by the user. After displaying the list of telephone numbers through the display unit 110, the control unit 100 proceeds to step 320 to determine whether there is a predetermined telephone number selection from the user in the displayed telephone number list. If there is no predetermined telephone number selection from the user, the control unit 100 returns to step 310. On the other hand, if there is a predetermined telephone number selection from the user among the telephone number list for the connection of the displayed answering machine service, the control unit 100 goes to step 330 to serve as the sub-set of the selected telephone number as shown in FIG. Display a list of menus. After displaying the submenu list of the selected phone number as described above, the controller 100 checks whether there is a predetermined submenu selection among the submenu list of the corresponding phone number displayed by the user in step 340. If there is no predetermined sub menu selection from the user, the process returns to step 330 again. On the contrary, when there is a predetermined submenu selection from the user, the control unit 100 proceeds to step 350 to connect the call to the answering service using the selected phone number to use the selected submenu. At the same time, when there is a predetermined submenu selection from the user among the submenu list of the predetermined telephone number, the controller 100 displays a dial key code string corresponding to the predetermined submenu as shown in FIG. do.

As such, after the call is connected to the answering machine, the controller 100 checks whether there is an input of a preset key through the key input unit 120 from the user in step 360. If a predetermined key is pressed by the user, the control unit 100 proceeds to step 370 and transmits a dial key code string input for use of a specific service one by one in correspondence with the input preset key. It ends. In this way, the control unit 100 determines whether the call is terminated in step 380, and returns to step 360 when the call is in a connected state. As such, the control unit 100 continuously checks whether a preset key is input from the user, and when a predetermined key is pressed by the user when using a specific service of the answering machine, the key of the dial key code sequence corresponds to the key press. Send out the codes one by one. If the user wants to use another service or the usual service of the answering machine is changed while this process is being performed, the user can use the service by using a cancellation key provided on the main body of the mobile terminal. have. For example, the control unit 100 may transmit the dial key code sequence every time a cancel key of the mobile terminal is pressed by the user. Skip keycodes one by one. Thereafter, when a predetermined key is pressed again by the user, the key code of the dial key code sequence, which is to be skipped and transmitted, is transmitted. As described above, the controller 100 skips each time a predetermined key is pressed and sequentially transmits key codes of the remaining dial key code strings one by one.

In the following description, a telephone number of an answering service is stored as 123-1234 and a dial key code string for using a specific service corresponding to the submenu is stored as 123 * 45678900 # 9 **. . If the user enters 123 * 456789 using the preset key after the call is connected to the answering service telephone number and the user does not want to use the next 00 #, the user presses the cancel key three times and dials the dial key code. You can skip the keycode of the column. Then, when the user presses a predetermined key again, the control unit 100 sequentially sends 9 ** one by one in response to the key press. On the other hand, if the user selects a dial key code to be sent by directly pressing a key of the mobile terminal without pressing a preset key while using the above functions of the answering machine, the next number of dial key code strings transmitted according to the key press is selected. You can step through the keycodes to be pressed one by one. This method can be applied when there is a change of a service frequently used by a user or when a user uses a specific service that has not been previously stored in an answering service.

In the above-described embodiment, in order to use the telephone number for connecting to the answering machine and the specific service thereof, the control unit 100 distinguishes the telephone number of the answering machine and the dial key code string for using the specific service. It is stored in memory as main menu and sub menu of service connection. Meanwhile, in another embodiment of the present invention, a telephone number for connecting to an answering service and a dial key code string for using a specific service thereof may be stored as a menu.

On the other hand, as a second embodiment, when the answering service telephone number is input from the user through the keypad and the call is connected, the process of the mobile telephone terminal is shown as shown in FIG.

Hereinafter, referring to FIG. 4, which is a control flowchart of a mobile phone terminal for retrieving the telephone number from a memory and using the answering machine after the call is connected to the telephone number for connecting to the answering machine according to the embodiment of the present invention. . First, when the answering service telephone number through the key input unit 120 is input from the user, the controller 100 asks whether the call is connected to the telephone number of the answering machine service input in step 400. If the call is connected, the control unit 100 proceeds to step 410 to search whether the call-connected phone number is stored in the memory. The controller 100 determines whether the answering service connected phone number stored in step 420 and the call-connected phone number match. If it does not match, the control unit 100 proceeds to step 430 to perform a function corresponding to a normal telephone call. On the contrary, when the answering machine connected phone number stored in the memory and the call-connected phone number match, the control unit 100 proceeds to step 440 and the sub corresponding to the phone number of the answering machine service that is matched through voice or screen. Informs that there is a menu list. The user may select one of a plurality of sub menu lists according to the voice or the guidance message on the screen. In operation 450, the controller 100 checks whether a preset key for selecting one of a plurality of sub-menu lists is input. The preset key pressed for the selection may be a submenu list number, for example. On the other hand, if there is only one sub-menu list, the user only needs to press one preset key to use a specific service. If a preset key is not input from the user, the controller 100 ends the call connection state of the answering machine. In contrast, when a preset key is input from the user for selecting a service list, the control unit 100 proceeds to step 460 and the dial key code string key for using a specific service stored in the memory corresponding to the input key. Send the code. Then, the control unit 100 determines whether the call is terminated in step 470 and returns to step 450 again in case of a call connection state to continuously check whether a preset key is input from the user. While continuously checking whether a key is input, the control unit 100 determines the call termination state in step 470, and when the call connected to the answering machine is terminated, the function 100 ends. When the user presses a predetermined key when the user is connected to the answering machine and uses a specific service, the controller 100 sequentially transmits the key codes of the dial key code sequence one by one in response to the key press.

As described above, the controller 100 allows a user to conveniently use a specific service of a frequently used answering service, and the key of the dial key code string for using a specific stored service whenever there is a predetermined key press from the user. It extracts the codes one by one and emits a DTMF (Dual Tone Multi-Frequency) signal as if the corresponding key was pressed. In other words, when a call is connected to the answering machine, the controller 100 automatically transmits the key code of the stored dial key code sequence to DTMF according to a preset key press by the user.

In order to obtain the dial key code sequence for using the specific service, the user must access the answering service at least once and store the dial key code left after using the specific service and the telephone number of the answering service in a memory. . In the future, when accessing the answering machine again, the user may access the answering machine by selecting a phone number for connection of the answering machine from the menu. Access to the answering service through the answering service connection menu is described above as the first embodiment, and the user accesses the answering service by directly dialing the telephone number of the answering service.

First, when accessing an answering service through the answering service connection menu according to the first embodiment, the controller 100 allows a user to select a submenu list of the answering service connection menu displayed on the display 110 to use a specific service. To be able. For example, the contents of the answering machine connection menu may include the telephone number pressed to access the answering service and the dial key displayed on the screen of the mobile phone terminal pressed by the user until the call is terminated to use the particular desired service. It consists of a code string. The telephone number and the dial key code string may be divided by a user and divided into a main menu and a sub menu list for an answering service connection or may be displayed as a single menu. Since the specific service may be several after being connected to one answering service, the controller 100 may include a plurality of sub-menu lists in one answering service telephone number. Therefore, the controller 100 requires a description to be input to each menu with a user-defined name in order to distinguish a plurality of service lists from a user. In other words, when the user wants to use the banking service, which is an answering service through the mobile phone terminal, the control unit 100 stores the number [1588-1234] connected with the call as a description input by the user called [ABC Bank Call Center]. And a dial key code string of [123 * 122324 #] entered to use a specific service such as bank transfer, including a description of [B bank account transfer]. In addition, when there are a plurality of specific services, the control unit 100 is divided into [1.B bank automatic transfer 2.C bank automatic transfer] and the like and displays the sub menu list through the display unit 110. When the user presses a predetermined key through the displayed sub-menu list, the key codes of the dial key code strings, such as the previously stored account numbers, are transmitted one by one in response to the key press. In this case, the preset key may be a side key of the mobile phone terminal or a numeric key which is an earphone key or a sub menu list number. In addition, a method of inputting a sub-menu list number may include a user using a numeric key provided in a mobile phone terminal or a mobile phone terminal that supports input or voice recognition through a soft key implemented on a touch screen. It is also possible to input via voice.

Meanwhile, when the user directly accesses the answering service by pressing the phone number of the answering service, according to the second embodiment, the controller 100 determines whether the connected answering service phone number is stored in the memory. If the connected answering service phone number matches the currently connected phone number, the controller 100 notifies the presence of a sub-menu list for using the answering service through voice or screen. If there is a sub-menu list selection including a dial key code string stored to use a specific service from the user, as described above, the key codes of the dial key code string are transmitted one by one in response to a preset key press.

In addition, the dial key code string for using the specific service of the answering service stored in the memory of the mobile telephone terminal according to the present invention may include important data such as an account number or a password. Therefore, in order to prevent external exposure of the dial key code string, the mobile phone terminal uses a restriction function and a protection function in such a manner as to require a password input or to make it invisible by encrypting it as in ******.

According to an embodiment of the present invention, a method for using an answering service using a mobile phone terminal may store a dial key code string for using a specific service of an answering service frequently used by a user to access a desired service. You can avoid the hassle of typing every time. In particular, even if the user presses only a predetermined key, for example, data such as an account number is automatically sent without pre-stored key input values, so that the user can easily use the specific service for convenience.
