Reference numeral 10 denotes an application processing unit that executes an application function included in the mobile terminal device. Reference numeral 11 denotes a timer that outputs current date and time information. Reference numeral 12 denotes a battery for supplying power for operating the mobile terminal device. Reference numeral 13 denotes a power control unit that switches the power of the mobile terminal device to an ON state or an OFF state by turning on / off the power of the battery 12. The power OFF state is a state in which power supply to most internal devices is stopped, but is a state in which the CPU 1 can be operated by shifting to a power saving sleep mode and at least the timer 11. Is a state in which the date / time information is being output to the CPU 1 and does not completely turn off the power of the battery 12. Reference numeral 14 denotes a UIM card in which user telephone number information and the like are written. Reference numeral 15 denotes a UIM card reader that reads information written in the UIM card 14.

  Next, an operation when the power of the mobile terminal device is turned on will be described with reference to FIG. First, the user turns on the power by pressing and holding the power key of the input unit 2 (step S1). The power ON state may be a state in which the power control unit 13 automatically turns on the power at a predetermined time. When detecting the power ON state, the CPU 1 detects whether the UIM card is inserted in the UIM card reader 15, and determines whether the UIM card 14 has been detected (step S2). As a result of this determination, if the UIM card 14 cannot be detected, the CPU 1 starts up in a state where the use of functions is restricted (step S5). When the UIM card 14 cannot be detected, the mobile terminal device starts up in a state where functions such as making / receiving calls, sending / receiving mails, Internet connection, address book reference, data folder expansion, and reproduction of copyright protection data cannot be used at all. Become.

  On the other hand, when the UIM card 14 can be detected, the CPU 1 performs UIM authentication (step S3). The UIM authentication here refers to the UIM key, PIN code, and parameters necessary for operating the mobile terminal device stored in the UIM card 14, read from the UIM card 14 via the UIM card reader 15, and the storage unit 9. And the location registration in the network is performed by the wireless communication unit 4. Subsequently, when the CPU 1 intends to activate the function of the mobile terminal device, the CPU 1 determines whether or not the setting that requires PIN authentication by PIN code input has been made (step S4). If it is determined that PIN authentication is required as a result of this determination, the CPU 1 starts up in a state where the use of the function is restricted (step S5). Similarly to the case where the UIM card 14 cannot be detected when the PIN authentication is required, such as making / receiving calls, sending / receiving mails, Internet connection, address book reference, data folder expansion, reproduction of copyright protection data, etc. The mobile terminal device is activated in a state where the function cannot be used at all. However, it can be used by inputting a PIN code every time each function is called (activated). The PIN code is a 4- to 8-digit number arbitrarily set by the user and corresponds to a password. If the setting is such that PIN authentication is not required, the CPU 1 activates the portable terminal device in a state where there is no restriction on usable functions. With this operation, the mobile terminal device is activated in a restricted or unrestricted state.

  Next, referring to FIG. 3, an operation for performing an alarm setting for sounding a predetermined musical tone at a preset elapsed time or set time will be described. First, the user operates the input unit 2 to perform an operation for starting an alarm function (step S11). In response to this, the CPU 1 outputs an instruction for setting an alarm function to the application processing unit 10. The application processing unit 10 displays a message for instructing input of setting items on the display unit 3. In response to this message, the user operates the input unit 2 to input items necessary for alarm setting, and inputs setting items until a registration instruction is given (steps S12 and S13). The items that should be set by the user here are the setting of the alarm time or elapsed time to sound the alarm, the selection of the musical sound (or music) to be sounded, and the automatic power-on function that automatically turns on the power immediately before the alarm function is activated. Whether to use or not. When the setting operation is completed, when the user operates the input unit 2 to perform registration, the application processing unit 10 holds the content of the setting item inside. Then, the application processing unit 10 refers to the storage unit 9 and determines whether or not an automatic power-off function that automatically turns off the power at a predetermined timing (for example, a set time) is set at the present time. (Step S14). The automatic power-off function is set in advance by the user, and the setting content is stored in the storage unit 9. If the automatic power-off function is not set as a result of this determination, the application processing unit 10 registers the alarm function setting item information stored in the storage unit 9 (step S21).

  On the other hand, when the automatic power-off function is set, the application processing unit 10 determines whether or not a musical sound or music that is to be sounded when the alarm function is activated is selected that requires PIN authentication (step S15). . As a result of the determination, if no musical sound or music that requires PIN authentication is selected, the application processing unit 10 registers the setting item information of the alarm function held therein in the storage unit 9 (step S21).

  Next, when a musical sound or music that requires PIN authentication is selected, the application processing unit 10 refers to the storage unit 9 and requires PIN authentication at the time of activation of each function whose activation is currently limited. It is determined whether or not the setting is correct (step S16). The setting as to whether or not the PIN authentication is necessary is a content that is set in advance by the user and stored in the storage unit 9. As a result of the determination, if the setting that requires PIN authentication has not been made, the application processing unit 10 registers the setting item information of the alarm function held therein in the storage unit 9 (step S21).

  On the other hand, if the setting requires PIN authentication, the application processing unit 10 displays a warning message on the display unit 3 (step S17). The message displayed here is: “If the PIN authentication necessity setting is not required, the selected musical sound (or music) cannot be played automatically. The PIN authentication necessity setting is set to be unnecessary. "This message is a message such as" Is it? ", Which notifies that the musical tone cannot be automatically reproduced in the current setting state, and inquires whether or not the PIN authentication necessity setting is set to be unnecessary. In response to this message, the user operates the input unit 2 and responds with “Yes” or “No”. The application processing unit 10 reads the response content and determines whether or not to set the PIN authentication unnecessary (step S18). If the user response is “Yes”, the application processing unit 10 switches to a setting that does not require PIN authentication, and updates the setting content stored in the storage unit 9 to make the setting that does not require PIN authentication. Replace (step S19). If the user's response is “No”, the application processing unit 10 resets the musical sound that is held inside and to be sung to a musical sound that does not require authentication (a musical sound that is preset in advance) (step S20). Then, the application processing unit 10 registers the alarm function setting item information stored in the storage unit 9 (step S21). With this operation, the setting contents of the alarm function are stored in the storage unit 9.

  Here, an operation for acquiring a musical sound (or music) to be sounded when the alarm function is activated will be described. When the input unit 2 instructs acquisition of the desired music from the network, the wireless communication unit 4 connects to a server on the communication network via a base station (not shown). At this time, for connection with a communication network or a base station, the application processing unit 10 executes a program for Internet connection processing in the storage unit 9, and the terminal ID stored in the UIM card 14 (detachable recording medium) is used. Use this to perform network authentication. The server transmits the music list to the mobile terminal device and displays the music list on the display unit 3. When the desired music is designated by the operation of the input unit 2, the designated music is downloaded from the server. At this time, it is determined whether or not the music data is data designated as a copyright protection target. The music data includes an area in which attached information is described in addition to actual sound information (data such as compressed voice, pitch, and tone color). In addition to the data size and playback format, this area also includes a copyright flag area to which a copyright flag (prohibition information) can be added when the creator of the music content wants to prohibit copying. .

  If the copyright data (prohibited information) is included as attached information in the downloaded music data, the portable terminal device associates the terminal ID used in the downloaded communication with the downloaded music data. Store in the storage unit 9. As a result, it is possible to protect the copyright so that it can be enjoyed only by the person who has downloaded it, for example, it cannot be played back on another portable terminal device even if the music data is copied.

  The UIM card 14 stores a PIN code (authentication code) in addition to the terminal ID as identification information. When playing music content subject to copyright protection, the terminal ID included in the UIM card 14 installed when playback is instructed matches the terminal ID associated with the music instructed to play. Judge whether to do. In the case of PIN authentication, the PIN code is read from the mounted UIM card 14, and it is determined by determining whether or not the combination (code) of characters / numerical values input from the input unit 2 matches. .

  Next, with reference to FIG. 4, an operation when the power of the portable terminal device is turned off by a user operation will be described. When detecting a long press of the power key by a user operation, the CPU 1 instructs the application processing unit 10 to execute processing when the power is turned off. In response to this, the application processing unit 10 refers to the storage unit 9 and determines whether or not the alarm function is currently set (step S31). As a result of this determination, if the alarm function is not set, the application processing unit 10 notifies the CPU 1 that the execution of the process at the time of power OFF is completed. On the other hand, when the alarm function is set, the application processing unit 10 determines whether or not a musical sound or music that is to be sounded when the alarm function is activated is selected that requires PIN authentication (step S32). As a result of this determination, if a tone or music that requires PIN authentication has not been selected, the application processing unit 10 notifies the CPU 1 that the execution of the process when the power is turned off has ended.

Next, when a musical sound or music that requires PIN authentication is selected, the application processing unit 10 refers to the storage unit 9 and requires PIN authentication at the time of activation of each function whose activation is currently limited. It is determined whether the setting is correct (step S33). The setting as to whether or not the PIN authentication is necessary is a content that is set in advance by the user and stored in the storage unit 9. As a result of this determination, if the setting that requires PIN authentication has not been made, the application processing unit 10 notifies the CPU 1 that the execution of processing at the time of power-off has been completed.

  On the other hand, if the setting requires PIN authentication, the application processing unit 10 displays a warning message on the display unit 3 (step S34). The message displayed here is: “If the PIN authentication necessity setting is not required, the selected musical sound (or music) cannot be played automatically. The PIN authentication necessity setting is set to be unnecessary. "This message is a message such as" Is it? ", Which notifies that the musical tone cannot be automatically reproduced in the current setting state, and inquires whether or not the PIN authentication necessity setting is set to be unnecessary. In response to this message, the user operates the input unit 2 and responds with “Yes” or “No”. The application processing unit 10 reads the response content and determines whether or not to set the PIN authentication unnecessary (step S35). If the user response is “Yes”, the application processing unit 10 switches to a setting that does not require PIN authentication, and updates the setting content stored in the storage unit 9 to make the setting that does not require PIN authentication. Replace (step S36). If the user's response is “No”, the application processing unit 10 resets the musical sound that is held inside and to be sung to a musical sound that does not require authentication (a musical sound that is preset in advance) (step S37). Subsequently, the application processing unit 10 notifies the CPU 1 that the execution of the processing when the power is turned off is finished.

  Next, when the CPU 1 receives a notification from the application processing unit 10 that the execution of processing at power-off has been completed, the CPU 1 disconnects from the network connected to perform communication with the wireless communication unit 4. Is instructed to execute. Receiving this, the wireless communication part 4 performs the process which cut | disconnects the connection to a network (step S38). Then, each processing unit stores parameters that need to be performed when the power is turned off in the storage unit 9 (step S39). Further, the CPU 1 displays a power OFF notification screen on the display unit 3 (step S40), shifts to the sleep mode, and instructs the power control unit 13 to turn off the power. Receiving this, the power supply control part 13 cut | disconnects the electric power supply with respect to each process part (step S41). With this operation, the power of the portable terminal device is turned off.

  Next, with reference to FIG. 5, an operation for calling and executing a desired function will be described. First, when the user turns on the mobile terminal device by pressing and holding the power key of the input unit 2, the mobile terminal device is restricted or unrestricted based on the above-described operation (the operation shown in FIG. 2). It will start in the state of. Here, when the user performs an operation of calling a desired function from the input unit 2, the CPU 1 outputs an instruction to activate the called function to the application processing unit 10 (step S51). In addition, in the case of a function that automatically starts up, such as an alarm function or an automatic power-on function, the application processing unit 10 refers to the date / time information output by the timer 11 and is set when the set time comes. Activate the function.

  Next, the application processing unit 10 refers to the storage unit 9 and determines whether or not the current state is a limited activation state based on whether or not the setting that requires PIN authentication is set (step S1). S52). As a result of this determination, if the current time is not a limited activation state (if PIN authentication is not required), the application processing unit 10 executes the called function (step S58). For example, if the setting is such that PIN authentication is not required when the power is turned off, the automatic power-on function turns the mobile terminal device into a power-on state with no restriction, and a musical sound or music pre-selected at the set time is displayed on the speaker 8. Will be played back and the alarm function will be executed.

  On the other hand, when the activation state is restricted at the present time, the application processing unit 10 determines whether or not the called function is a restricted function (step S53). As a result of the determination, if the called function is not a function to be restricted, the application processing unit 10 executes the called function (step S58).

  Next, if the called function is a function to be restricted, the application processing unit 10 determines whether or not the UIM card 14 is inserted in the UIM card reader 15 (step S54). If the UIM card 14 is not inserted as a result of the determination, the application processing unit 10 displays a message for requesting the UIM card insertion on the display unit 3 and ends the process.

  On the other hand, if the UIM card 14 is inserted, the application processing unit 10 displays a message requesting the PIN code input on the display unit 3 (step S56). Here, the user inputs a preset PIN code from the input unit 2. The application processing unit 10 determines whether or not the input PIN code is correct (step S57), and if the input PIN code is correct, executes the called function (step S58). . If the input PIN code is not correct, the application processing unit 10 displays a message requesting the PIN code input again. If an incorrect PIN code is input a predetermined number of times (for example, three times), the application processing unit 10 displays an error message indicating that the called function cannot be executed on the display unit 3 for processing. Exit. By this operation, when a desired function is called, a PIN code input is requested, and if the inputted PIN code is valid, the called function is executed.

  In this way, when performing a setting to automatically activate a function that requires authentication immediately before activation, it is determined whether the authentication operation is not required, and the authentication operation is not required. Since a warning message is displayed when a setting is not set, a function that is set to start automatically can be started reliably. In addition, a warning message is displayed immediately before the power is turned off, and the setting for switching to a setting that does not require PIN authentication is performed immediately before the power is turned off according to a user response. The time during which the device is used can be shortened as much as possible.
