The ringer 122 generates a ring tone under the control of the controller 100, and the vibrator 124 generates vibration under the control of the controller 100.

The functions provided in the portable telephone as described above are becoming increasingly complex and diverse. Accordingly, various functional items have been adopted to classify related items among the related items and go from the main menu to the sub menu. In this case, the user has found and selected the desired function item according to the menu search procedure from the main menu to the submenu.

Figure 2 shows a menu search flow diagram for the conventional function selection accordingly. Referring to Figure 2 will be described with respect to the conventional function selection. First, when a user inputs a menu button 200 on the keypad 104 of FIG. 1, the controller 100 displays a main menu 202 including main menu items on the display unit 106 as shown in FIG. 2. The user then selects a main menu item including a desired function item among the main menu items of the main menu 202 by a key on the keypad 104. At this time, a numeric key or a search key is usually used as the selection key. Then, the controller 100 displays the submenu 204 including the submenu items belonging to the selected main menu item through the display unit 106. At this time, if there is another submenu in the submenu item selected by the user in the submenu 204, the display unit 106 displays the submenu 206 including other submenu items belonging to the submenu item. . At this time, if there is a submenu item corresponding to a function item desired by the user among the submenu items of the submenu 206, the user selects the function item to execute a desired function.

As described above, the user searches for a sub-menu step by step starting with the main menu, finds a desired function item, and selects and executes a desired function. As a result, the user was troublesome to operate the keys in several steps from the main menu to selecting the desired function item. In addition, if you do not know the submenu or main menu to which the desired function item belongs, it took considerable time and effort to find the desired function item.
