           [0005]    A portable radio telephone, especially a GSM (Global System for Mobile communication) mobile phone utilizing the CDMA (Time Division Multiple Access) technology, includes a SIM (Subscriber Identification Module) card in which various data including subscriber information is stored. The data stored in the SIM card includes phone numbers and network IDs as well as information needed to operate the portable radio telephone, i.e., subscriber information such as a password.  
           [0006]    A service menu for the user of the portable radio telephone is provided by a customer service profile (CSP) function stored in the SIM card, and is displayed through the portable radio telephone according to CSP information stored in the SIM card.  
           [0007]    Though many service menus are provided for the use of the portable radio telephone, typically only a few of the menus are frequently used by the user. In general, the menus each include their sub-menus, so that the user must press many keys in order to select a desired sub-menu. For example, referring to FIG. 2, in order to set an alarm through the portable radio telephone, the user must first select a time setting menu having a main menu index #8 out of 9 main menus. Typically, the nine main menus include: a volume control menu having a main menu index #1, a utility menu having a main menu index #2, a system setup menu having a main menu index #3, an alert menu having a main menu index #4, an air time (or call time) menu having a main menu index #5, a security menu having a main menu index #6, a display menu having a main menu index #7, a time setting menu having a main menu index #8, and a voice recognition menu having a main menu index #9. Thereafter, the user must select an alarm setting sub-menu having a sub-menu index #2 out of 5 sub-menus of the time setting menu. As shown in FIG. 2, the five sub-menus for the time setting menu #8 include: a time setting sub-menu having a sub-menu index #1, an alarm setting sub-menu having a sub-menu index #2, an anniversary input sub-menu having a sub-menu index #3, a time reserving sub-menu having a sub-menu index #4, and a world time sub-menu having a sub-menu index #5. That is, in order to select a desired menu, the user must annoyingly search the menus and thus press many keys

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0016]    A preferred embodiment of the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.  
         [0017]    [0017]FIG. 1 shows a block diagram of a portable radio telephone to which the present invention is applicable.  
         [0018]    Referring to FIG. 1, a controller  111  controls the overall operation of the portable radio telephone. A memory  113  stores a control program of the portable radio telephone and control data generated from the controller  111 . Particularly, in an embodiment of the present invention, the memory  113  stores service menu information registered in the SIM card and a user-customized menu created by the user. A key input unit  115  includes at least a plurality of alphanumeric keys, a MENU key and a SEND key, and generates a key signal according to a key pressed by the user. The generated key signal is provided to the controller  111 .  
         [0019]    A voice memory  117  stores a plurality of voice messages. A voice processor  119 , under the control of the controller  111 , converts the voice message read out from the voice memory  117  to an analog voice signal and outputs the converted voice signal through a speaker SPK. Further, the voice processor  119  converts an analog voice signal input by the user through a microphone MIC to a digital voice signal and demodulates a voice signal received from the other party.  
         [0020]    A transmitter  121  modulates a signal provided from the controller  111  into a radio signal and provides the modulated radio signal to a duplexer  123 . The duplexer  123  radiates the radio signal provided form the transmitter  121  through an antenna ANT, and provides a radio signal received through the antenna to a receiver  125 . The receiver  125  demodulates the radio signal provided from the duplexer  123  and provides the demodulated signal to the controller  111 . The controller  111  controls a call according to the provided radio signal. A display  127 , which is typically implemented by an LCD (Liquid Crystal Display) or an LED (Light Emitting Diode), displays control data and input data of the portable radio telephone, under the control of the controller  111 .  
         [0021]    [0021]FIG. 2 shows a menu table included in the portable radio telephone by way of example.  
         [0022]    Referring to FIG. 2, the menu table includes 9 main menus, which include a volume control menu having a main menu index #1, a utility menu having a main menu index #2, a system setup menu having a main menu index #3, an alert menu having a main menu index #4, an air time (or call time) menu having a main menu index #5, a security menu having a main menu index #6, a display menu having a main menu index #7, a time setting menu having a main menu index #8, and a voice recognition menu having a main menu index #9. The main menus each include their sub-menus as shown. For example, the volume control menu #1 includes a bell volume sub-menu having a sub-menu index #1, a key tone volume sub-menu having a sub-menu index #2, and a speech volume sub-menu having a sub-menu index #3.  
         [0023]    [0023]FIG. 3 shows a procedure for creating a user-customized menu according to an embodiment of the present invention, and FIG. 4 shows a user-customized menu table according to an embodiment of the present invention, by way of example.  
         [0024]    With reference to FIGS. 3 and 4, a detailed description will be made below regarding a procedure for creating the user-customized menu according to an embodiment of the present invention.  
         [0025]    Upon receipt of a key signal provided from the key input unit  115 , the controller  111  determines in step  311  whether the provided key signal is a user-customized menu creating key. If it is not a user-customized menu creating key, the controller  111  proceeds to step  313  where the controller  111  performs an operation corresponding to the key signal provided from the key input unit  115 .  
         [0026]    Otherwise, if the key signal provided from the key input unit  115  is the user-customized menu creating key, the controller  111  proceeds to step  315  where the controller  111  switches an operating mode of the portable radio telephone to a user-customized menu creating mode. Thereafter, in step  317 , the controller  111  displays through the display  127  a user-customized menu index input request message stored in the memory  113  to request the user to input a desired user-customized menu index. For example, the message may be read “Please input a user-customized menu index.” 
         [0027]    In step  319 , the controller  111  determines whether a key signal corresponding to a user-customized menu index is received from the key input unit  115 . Upon failure to receive the user-customized menu index key signal, the controller  111  determines in step  321  whether a preset time (e.g., 5 seconds) has elapsed. If the preset time has not elapsed, the controller  111  returns to step  319 . Otherwise, if the preset time has elapsed, the controller  111  proceeds to step  331 , where the controller  111  releases the user-customized menu creating mode and then ends the program.  
         [0028]    If, for example, the user-customized menu index #1 is received in step  319 , the controller  111  proceeds to step  323  wherein the controller  111  displays through the display  127  a message requesting the user to input a corresponding menu index designating the menu contents to be stored in the received user-customized menu index. For example, the message may be read “Please input a desired menu index.” Thereafter, the controller  111  determines in step  325  whether a key signal corresponding to a menu index is received from the key input unit  115 . Upon failure to receive the menu index key signal, the controller  111  determines in step  327  whether a preset time (e.g., 5 seconds) has elapsed. If the preset time has not elapsed, the controller  111  returns to step  325 . Otherwise, if the preset time has elapsed, the controller  111  proceeds to step  331 , where the controller  111  releases the user-customized menu creating mode and then ends the program.  
         [0029]    If, for example, a menu index #11 indicating a bell volume sub-menu is received in step  325 , the controller  111  proceeds to step  329  where the controller  111  maps the received index to the menu, and stores the received user-customized menu index ‘11’ in a user-customized menu storage area of the memory  113 . Thereafter, in step  331 , the controller  111  releases the user-customized menu creating mode and then ends the program.  
         [0030]    As described with reference to FIGS. 3 and 4, it is possible to create a separate menu, i.e., the user-customized menu composed of the most frequently used service menus such as the bell volume menu, the bell select menu, the alarm setting menu, the initial screen menu, and the key tone volume menu.  
         [0031]    [0031]FIG. 5 shows a procedure for performing the user-customized menu according to an embodiment of the present invention.  
         [0032]    Referring to FIG. 5, upon receipt of a key signal provided from the key input unit  115 , the controller  111  determines in step  511  whether the provided key signal is a user-customized menu key signal. If it is not the user-customized menu key signal, the controller  111  proceeds to step  513  whether the controller  111  performs an operation corresponding to the key signal provided from the key input unit  115 .  
         [0033]    If, however, the key signal provided from the key input unit  115  is the user-customized menu key signal in step  511 , the controller  111  proceeds to step  515  where the controller  111  reads out a previously created user-customized menu from the user-customized menu storage area of the memory  113  and displays the read user-customized menu on the display  127 . Thereafter, the controller  111  determines in step  517  whether a menu select key is received from the key input unit  115 . Here, the “menu select key” refers to an alphanumeric key corresponding to the user-customized menu index previously set in the user-customized menu. For example, in FIG. 4, the bell volume menu is set to the user-customized menu index #1, so that a menu select key for selecting the bell volume menu becomes ‘1’.  
         [0034]    Upon failure to receive the menu select key in step  517 , the controller  111  proceeds to step  519  where the controller  111  determines whether a preset time (e.g., 5 seconds) has elapsed. If the preset time has not elapsed, the controller  111  returns to step  517 . Otherwise, if the preset time has elapsed, the controller  111  ends the program.  
         [0035]    However, upon receipt of the menu select key from the key input unit  115  in step  517 , the controller  111  proceeds to step  521  where the controller  111  performs an operation corresponding to the menu selected according to the menu select key signal and then ends the program.  
         [0036]    As described above, the portable radio telephone according to the present invention can create a user-customized menu composed of frequently used service menus, making it possible for the user to quickly search the frequently used menus and input the searched menu with a reduced number of key strokes. In addition, the user can freely create his unique customized menu personally. Thus, the novel portable radio telephone offers convenience to the user.  
         [0037]    While the invention has been shown and described with reference to a certain preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
