As shown in the drawing, the mobile communication terminal 100 includes a control unit 110, an I O interface 120, memory 130, a wireless communication unit 140, a display unit 150, an incoming call infonriation security management unit 160, an application storage unit 170 and a voice output unit 180. In the case of a mobile communication terminal for performing local area communication, the mobile communication module must be provided with a local area communication module. The I/O interface 120 for performing VO control, the memory 130 for storing various data, the wireless communication unit 140 for performing wireless communication, the display unit 150 for displaying the current status of the mobile communication terminal 100 or the processing status of an event requested by a user, and the voice output unit 180 for audibly providing data at the time of using a voice communication service or data service are the common elements of mobile communication tenriinals, so that detailed descriptions thereof are omitted. The mobile communication terminal 100 applied to the present invention further includes the incoming call information security management unit 160 and the application storage unit 170. The incoming call information security management unit 160 registers the tenriinal numbers of target vvTred wireless communication terminals inputted by the user of the mobile communication tenriinal 100, and manages information on call reception and SMS message arrival from the target wired wireless communication terminals based on the type of incoming call alarm, a telephone number list management condition and a call list management condition previously set by the user. In this case, the mobile communication terminal 100 includes a switching menu for switching between a common call mode and an incoming call information security mode. Accordingly, the incoming call information security mode can be released so that, when calls are received from the target vvired/wireless communication terminals (including the arrival of an SMS message) in the common call mode, a call connection procedure identical to that which is performed when calls are received from common wired/wireless communication terminals can be performed. In this case, in order to switch the mobile communication terminal 100 from the common call mode to the incoming call information security mode, a preset unique code (a password in the form of characters, numbers, symbols or a combination thereof) must be inputted. The password may be composed of, for example, a combination of numbers, such as a telephone number 011 100 0000. If the user inputs a telephone number, which is set as the password, to the mobile communication terminal 100 and then selects a call button, a method in which the password is not indicated in a call list and the mobile communication terminal 100 is switched to the incoming call information security mode can be used. The application storage unit 170, in which an application program is installed according to the type or model of the mobile communication terminal 100 and information for supporting services relating to the application program is stored, stores an incoming call information security program for managing information on call reception from wired/wireless communication terminals that are registered in the mobile communication terminal 100 as security targets. In this case, the operators of an independent server and a mobile communication network may create and manage the incoming call information security program, and transmit the incoming call information security program to the mobile communication terminal 100 at the request of the mobile communication terminal 100. Further, the incoming call information security program may be installed in a terminal at the time of manufacture. FIG. 2 is a detailed diagram illustrating the construction of the incoming call information security management unit 160 of the mobile communication tenriinal 100 according to the present invention, which is described with reference to FIG. 5 illustrating an example of the arrangement of a call list. The incoming call information security management unit 160 includes a menu storage unit 70 for storing target wired/wireless communication tenriinal number registration items and incoming call information security setting items for managing information on call reception from registered target wired wireless communication terminals, a menu provision unit 10 for extracting the incoming call information security setting items from the menu storage unit 70 and providing the extracted items to the mobile communication terminal 100 so that they are displayed on the screen of the mobile communication terminal 100, a security editing unit 30 for registering the terminal numbers of target wired wireless communication tenriinals inputted by the user, or setting the type of incoming call alarm, a security setting information storage unit 90 for storing the security setting information received from the security editing unit 30, and a security execution unit 50 for managing information when calls are received from the target wired/wireless communication terminals, based on the information stored in the security setting information storage unit 90. In more detail, the menu storage unit 70 stores a security editing menu for setting the terminal numbers of target wired/wireless communication tenriinals, the type of incoming call alarm, a telephone number management condition, a call list management condition, a mode switching condition, a condition for the restoration of the terminal numbers of target vvired/wireless communication tenriinals, and an SMS message management condition. The menu provision unit 10 extracts a relevant menu (for registering the terminal numbers of target wired/wireless communication terminals, setting the type of incoming call alarm, setting a telephone number management condition, setting a call list management condition, setting an SMS message management condition, setting a mode switch, or setting a condition for the restoration of the terminal numbers of target wired/wireless communication tenriinals) from the menu storage unit 70 in response to a signal input from the mobile communication terminal 100, and then sends the extracted menu to the control unit 110 so that the menu can be displayed on the screen of the mobile communication terminal 100. The security editing unit 30 registers the terminal numbers of target wired/wireless communication terminals inputted by the user, and sets the type of incoming call alarm (one of a silent lamp, vibration, bell sound and no display) with respect to call reception from the target wired/wireless communication terminals. In this case, the terminal numbers of the target wired/wireless communication terminals, which are registered in the security editing unit 30, can be modified. Further, the security editing unit 30, as shown in FIG. 5, can set conditions (the call list management condition and the telephone number management condition) so that the terminal numbers of target wired/wireless communication terminals can be replaced with the terminal numbers of wired/wireless communication terminals other than the terminal numbers of the target wired/wireless communication tenriinals on the call list and the telephone number management list that are created when calls are established with wired/wireless communication terminals. Moreover, the security editing unit 30 performs setting so that the terminal numbers of the target wired wireless communication terminals are deleted from the call list and the telephone number management list. Thereafter, the security editing unit 30 can perform setting so that the terminal numbers of the target wired/wireless communication terminals, which were replaced with other terminal numbers or deleted from the call list and the telephone number management list, are restored according to the user's input. The security editing unit 30 performs setting so that arrival notification and sender information regarding SMS messages received from target wired/wireless communication terminals are not displayed on the screen of the mobile communication tenriinal 100, are stored in the memory, and are then extracted and displayed at the request of the user. The security setting information storage unit 90 stores the terminal numbers of target wired/wireless communication terminals, the type of incoming call alarm, the call list management condition, the telephone number management condition and the SMS message management condition, which are received from the security editing unit 30. If a call is received from one of wired/wireless communication terminals, the security execution unit 50 determines whether the wired/wireless communication terminal is one of the target wired/wireless communication tenriinals by comparing the call with the information stored in the security setting information storage unit 90, and manages information on call reception from the target wired/wireless communication terminals, based on the predetermined type of incoming call alarm (one of the silent lamp, vibration, bell sound and no display). In this case, if the type of incoming call alarm is no display, the security execution unit 50 stores information on call reception from the target wired/wireless communication terminals in the memory without displaying the call reception information on the screen of the mobile communication terminal 100, and then displays the call reception information on the screen of the mobile communication terminal 100 at the request of the user. In this case, the security execution unit 50 may inform the user of call reception in a message arrival notification form in which a sender is not indicated. For example, if a call is received from one of the target wfred/wireless communication terminals, the security execution unit 50 displays information on a screen in a message arrival notification form, such as "ding-dong," "a message has arrived" and "there is one message unopened," and then extracts and displays call reception information (including sender information), which is stored in the memory, at the request of the user (the input of a predetermined unique code for checking call reception information). In this case, the information on call reception from the target wired/wireless communication terminals can be stored in the additional memory of the mobile communication terminal 100 used to store call reception information from the target wired/wireless communication terminals, or is assigned an identification code indicating target call reception information and is stored in the existing memory. Furthermore, the security execution unit 50 can delete the terminal numbers of target wired wireless communication tenriinals from the telephone number management list and the call list, or replace them with terminal numbers other than the terminal numbers of the target wired/wireless communication terminals, based on the telephone number management condition and the call list management condition set in the security editing unit 30. In addition, if a request for the restoration of the terminal numbers of target wired/wireless communication terminals is received from the user, the security execution unit 50 can restore the terminal numbers of the target wired/wireless communication terminals, which were deleted or replaced with other terminal numbers on the call list and the telephone number management list. The security execution unit 50 stores an SMS message, which is received from one of the target wired/wireless communication terminals, in the memory, without displaying the arrival notification and sender information of the SMS message on the screen of the mobile communication terminal 100, and then displays the stored SMS message on the screen of the mobile communication terminal 100 at the request of the user. In this case, the SMS message received from the target wired/wireless communication terminal may be stored in the additional memory of the mobile communication terminal 100 for storing target SMS messages, or is assigned an identification code indicating a target SMS message and stored in the existing memory. FIG. 3 is a flowchart illustrating a method of managing incoming call information using the mobile communication terminal 100 according to an embodiment of the present invention. The method is described with reference to FIG. 5 illustrating an example of the arrangement of a call list. The mobile communication tenriinal 100 displays a menu for selecting a security editing mode or security execution mode at step SlOl. In this case, in order to select the security editing mode or security execution mode, a predetermined unique code (a password in the form of characters, numbers, symbols and a combination thereof) must be inputted. The password may consist of, for example, a combination of numbers such as a telephone number 011 100 0000. If the user inputs a telephone number, which is set as the password, to the mobile communication terminal 100 and then selects a call button, a method in which the password is not displayed on the call list and the mobile communication tenriinal 100 is switched to the incoming call information security mode may be used. If the security editing mode is selected at step SlOl, the mobile communication terminal 100 displays items, such as the registration of the terminal numbers of target wired/wireless communication tenriinals, the setting of the type of incoming call alarm, the setting of the call list management condition, the setting of the telephone number management condition, and the setting of the restoration of the terminal numbers of target wfred/wireless communication terminals, so that the user can set a security condition at step SI 03. In this case, the type of incoming call alarm may be one of a silent lamp, vibration, bell sound and no display. Thereafter, the mobile communication tenriinal 100 registers the terminal numbers of the target wired wireless communication tenriinals based on the security condition set by the user, or sets an incoming call information management condition for managing information when calls are received from the target wired/wireless communication terminals at step SI 05. The mobile communication tenriinal 100 determines whether to finish the editing at step
S 107, and finishes the editing or repeats the steps after step SlOl according to the input of the user. Meanwhile, if the security execution mode is selected at step SlOl and a call is received from one of the wired/wireless communication terminals at step 109, the mobile communication terminal 100 determines whether the wired/wireless communication terminal is one of the target wired/wireless communication teπninals by comparing information on call reception from the wired/wireless communication tenriinal with the terminal numbers of the target terminals that are stored in the security setting information storage unit 90 at step Si ll. If the wired/wireless communication terminal is one of the target wired/wireless communication tenriinals at step SI 11, the mobile communication terminal 100 checks security setting information (the type of incoming call alarm, the call list management condition, the telephone number management condition, etc.), which is stored in the security setting information storage unit 90 at step
S113. The security execution unit 50 manages the information on call reception from the target wired/wireless communication terminal, according to the result of the COnfirmation at step SI 13, at step S115. Items that the security execution unit 50 manages to manage the information on call reception from the target wired wireless communication tenriinals at step SI 15 may be divided into three types: the type of incoming call alarm, a call list management condition, and a telephone number list management condition. First, a method of managing information on call reception from the target wired/wireless communication terminals using the incoming call alarm is performed by setting the type of incoming call alarm, that is, one of a silent lamp, vibration, bell sound and no display, which is inputted by the user, on each terminal, and applying the set incoming call alarm to a call when the call is received from one of the target wired/wireless communication terminals. In this case, if the type of incoming call alarm is no display, the mobile communication terminal 100 can store the call received from the target wired/wireless communication terminals in the memory, without displaying the call reception information on the screen of the mobile communication terminal 100, and then display the stored call on the screen of the mobile communication terminal 100 at the request of the user. In this case, a method in which the mobile communication terminal 100 informs the user of call reception in a message arrival notification form in which a sender is not indicated may be used. For example, when a call is received from one of the target wired/wireless communication terminals, the mobile communication terminal 100 displays information on the screen thereof in a message arrival notification form, such as "ding-dong," "a message has arrived" and "there is one message unopened," and then extracts and displays call reception information (including sender information) that is stored in the memory at the request of the user (the input of the predetermined unique code for checking call reception information). In this case, the information on call reception from the target wired wireless communication terminal can be stored in the additional memory of the mobile communication terminal 100 for storing target call reception information, or can be assigned an identification code indicating call reception information and stored in the existing memory. Second, a method of managing infonriation on call reception from target wired/wireless communication terminals using the call list management is performed by deleting the call reception history from the target wired/wireless communication tenriinals, or replacing the terminal numbers of target vvired/wireless communication tenriinals with terminal numbers other than the terminal numbers of the target wired/wireless communication terminals, as shown in FIG. 5. Irrird, a method of managing information on call reception from target wired/wireless communication terminals using the telephone number management is performed by deleting the terminal numbers of one or more target wired/wireless communication terminals that are stored in the mobile communication tenriinal 100, or replacing the terminal numbers of target wired wireless communication terminals with terminal numbers other than the terminal numbers of the target wired/wireless communication terminals. After step SI 15, if the security execution unit 50 receives requests for the restoration of the terminal numbers of target wired wireless communication terminals from the user, the security execution unit 50 restores the terminal numbers of the target v red/wireless communication terminals that were replaced with other terminal numbers or deleted on the call list and the telephone number list. FIG. 4 is a flowchart illustrating a method of managing incoming call information using the mobile communication terminal 100 according to another embodiment of the present invention. If the mobile communication terminal 100 receives an SMS message from a wfred/wireless communication terminal at step S201, the mobile communication tenriinal 100 determines whether the wired/wireless communication terminal is one of the target wired/wireless communication terminals by comparing the number of the wired/wireless communication terminal that sent the SMS message, with the terminal numbers of the target terminals that are stored in the security setting information storage unit 90 at step S203. If, as a result of the step S203, the wired/wireless communication terminal is one of the target wired/wireless communication tenriinals, the mobile communication terminal 100 stores the SMS message in the memory without displaying it on the screen at step S205. In this case, the SMS message transmitted from the target wired/wireless communication terminal may be stored in the additional memory of the mobile communication tenriinal 100 for storing target SMS messages, or may be assigned an identification code indicating an SMS message and stored in the existing memory. At step S205, the mobile communication terminal 100 checks an SMS message setting condition stored in the security setting information storage unit 90. If the SMS message received from the target wired/wireless communication tenriinals is not additionally managed, the mobile communication terminal 100 applies a procedure identical to that applied to an SMS message received from common wired/wireless communication tenriinals to the SMS message. Thereafter, if a request for the checking of the SMS message is received from the user at step
S207, the mobile communication terminal 100 determines whether the user is an authentic user by requesting the user to input a unique code necessary to check the SMS message at step S209. In this case, the unique code is any one of characters, numbers, symbols or a combination thereof, and may be set to be the same as or different from a unique code that is inputted upon executing incoming call information security. If, as a result of step S209, the unique code of the user is the same as the preset unique code at step S209, the mobile communication teiminal 100 extracts the stored SMS message and displays it on the screen at step S211. If the unique code of the user is different from the preset unique code at step
S209, the mobile communication terminal 100 displays a message, which indicates that the SMS message cannot be opened, on the screen (not shown). If, as a result of step S203, the wired/wireless communication tenriinal is not one of the target wired/wireless communication terminals at step S203, the mobile communication terminal 100 displays a message SMS message notification message on the screen at step S213 and then performs the steps after step S211. Although only the SMS message of various messages that are received from the target wired/wireless communication tenriinals has been described as an example, the message may has a multi-message form that is composed of one of characters, voice, a moving image and a combination thereof.
