Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a mobile phone terminal having a lock function, and more particularly to a mobile phone terminal that sets a user-usable function for each lock level.
[0002]
[Prior art]
  2. Description of the Related Art Conventionally, some mobile phone terminals have a function of locking a dial so that a person other than the user cannot use it (hereinafter referred to as a dial lock function) and a key lock function for preventing malfunction. The following are disclosed as conventional techniques related to such a dial lock function and a key lock function.
[0003]
  For example, Japanese Patent No. 3012599 discloses a detection unit that detects that a key operation is not performed within a predetermined time after the key operation is completed when the power is on and on hook, and the detection unit. Means for restricting the key operation when it is detected that the key operation is not performed within the predetermined time, and pressing a specific key preset when the key input is invalid In response to the key operation, and the specific key has a pressing surface lower than the pressing surfaces of the other keys installed on the same plane (mobile phone) Technology relating to telephone terminals) is disclosed.
  According to this prior art, the key lock state can be released simply by pressing the specific key, and the key pressing surface for releasing the key lock setting state is arranged at a position lower than the pressing surfaces of other keys. Therefore, it is possible to prevent the specific key from being pressed unintentionally by the user during storage.
[0004]
  Also, in Japanese Patent No. 3022832, when a lock setting key provided outside is operated, the control unit of the external medium transmits a lock setting request signal, and the control unit of the mobile phone (mobile phone terminal) main body transmits the signal. The control unit of the mobile phone body transmits an ID inquiry signal, the control unit of the external medium receives the signal within α time after transmitting the lock setting request signal, and the external The control unit of the medium transmits an ID response signal, the control unit of the mobile phone body receives the signal within β time after the transmission of the ID inquiry signal, and the control unit of the mobile phone body receives the received ID A technique related to a dial lock method for a mobile phone using an external medium including a step of collating IDs of response signals and setting a lock if they match is disclosed.
  According to this prior art, the lock is not set or released by the key operation of the mobile phone (mobile phone terminal), and the mobile phone (terminal) can be sent to a third party as long as the user holds the external medium. The risk of releasing the dial lock can be made extremely low.
[0005]
  Japanese Patent Laid-Open No. 2000-188783 discloses an automatic operation method for a mobile phone using a mobile phone having a specified number memory for storing a specified number and a password memory for storing a password. If it is not a read from the designated number, an automatic response is made, while if it is a read from the designated number, it waits for the input of the password and the input A technique of an automatic operation method for a mobile phone that performs a preset automatic operation when the password matches a password stored in a password memory is disclosed.
  According to this prior art, in response to a call from a preset number, when a mobile phone is misplaced, lost, stolen, etc. due to a password, etc., it can be locked or in answering machine mode, Various operations such as displaying a specified message can be performed.
[0006]
  When the user changes the setting of the mobile communication terminal during the operation of the dial lock function or the key lock function (hereinafter, the function that restricts the functions available to the user is referred to as the lock function), Release these lock functions, change the settings, and then perform dial lock settings or key lock settings (hereinafter, settings that limit the functions used in this way are referred to as lock settings), and the original dial lock It is necessary to return to a state or a key lock state (hereinafter, a state that restricts functions used in this way is referred to as a lock state).
[0007]
  As described above, the conventional mobile phone terminal imposes a great deal of effort on the user, so that the usability is extremely poor.
  For example, when only a slight setting change is performed, the locked state is returned to the normal state and the normal state is returned to the locked state after the setting is completed, compared to the labor required for the setting change (number of key inputs and setting time). In some cases, the labor for this would be greater.
[0008]
  In particular, in recent years, mobile phone terminals have become multifunctional and are used not only as telephones but also for many services. As described above, as the positioning of the mobile phone terminal is no longer a mere contact item, and the information terminal stores a large amount of information, the user often keeps the terminal locked so that it is not used by others. .
[0009]
  However, with such multi-functionality, the frequency of use of the mobile phone terminal becomes higher than before. That is, since the user frequently uses the mobile phone terminal, the user has to frequently perform an operation of returning the terminal from the locked state to the normal state and returning to the locked state after the use is completed.
[0010]
  On the other hand, in Japanese Patent Laid-Open No. 10-257170, when a specific password and a destination telephone number are input while in the dial lock setting state, the dial lock setting state is canceled and the destination telephone number The first prior art relating to a mobile phone terminal that returns to the dial lock setting state when the call is terminated and the call is terminated is disclosed.
[0011]
  Japanese Patent Laid-Open No. 11-355432 discloses an input operation of a personal identification number for releasing the dial lock during the dial lock setting, and an input operation of a selection key for releasing the dial lock or a selection key for temporarily releasing the dial lock. If the entered personal identification number is correct, a second prior art relating to a mobile communication terminal that performs dial lock release by releasing or temporarily releasing an input operation is disclosed.
[0012]
[Problems to be solved by the invention]
  However, according to the first prior art, when dialing in the dial lock setting state, it is only necessary to input the other party's telephone number after the specific password, and automatically when the call is finished. Returning to the dial lock setting state, no countermeasures are shown for the use of functions other than calls. In particular, because today's mobile phone terminals are increasingly used for functions other than telephones, the first conventional technology says that no countermeasures are provided for the above problems. Is not an exaggeration.
[0013]
  In addition, according to the second prior art, it is possible to select whether to cancel the dial lock setting or to cancel temporarily, but when releasing it, a release operation is required as in the conventional case. Also, since the method for releasing the dial lock setting must be determined before the release, after selecting the temporary release and performing an operation, if further operation is required, the lock setting must be released again. It must be made.
[0014]
  The present invention has been made in view of the above problems, and by providing a level for the lock function and defining a function that can be used for each set level, a function that is frequently used according to the user's usage environment An object of the present invention is to provide a mobile phone terminal that can be used even in a locked state.
[0015]
  That is, an object of the present invention is to provide a mobile phone terminal that can use a predetermined function without releasing a lock state.
  In addition, by specifying the functions that can be used for each lock level, the user can specify a lock level and provide a mobile phone terminal that realizes function restrictions in accordance with the usage status and environment. To do.
[0016]
  It is another object of the present invention to provide a mobile phone terminal that can be lent to others in a state in which only a specific function can be used by providing a level for the lock function and limiting the functions that can be used.
  In particular, it is an object of the present invention to provide a mobile phone terminal that cannot be viewed or changed by others, such as information and settings that cannot be viewed or changed by others, such as user personal information.
[0017]
  Further, it is possible to provide a mobile phone terminal that releases a lock state when information such as a password is input and matches information stored in advance.
[0018]

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0033]
  The mobile phone terminal according to the present invention refers to a correspondence table of functions that are prohibited (locked) by the user for each lock level, lock state storage means for storing the lock level of the terminal, and the correspondence table, When the control means for locking the function prohibited from use by the user at the lock level stored in the lock state storage means and the lock level change command from the user satisfy a predetermined condition, the lock state storage means Setting means for setting a lock level instructed by the user.
[0034]
  When the lock level instructed by the user is a level enabling the function to be locked at the lock level stored in the lock state storage means, the predetermined condition is that the user transitions to the lock level. It is good also as a condition that the information of this was input.
[0035]
  Further, when the lock level designated by the user is a level that does not enable the function to be locked with the lock level stored in the lock state storage means, the lock level change instruction satisfies the predetermined condition. It is good as it is.
[0036]
  The information for transitioning to the lock level can be arbitrarily set. For example, it may be the same number as a predetermined password, the same password as a predetermined password, or The above number and password may be used. That is, when transitioning to a lock level for releasing a locked function, an input of a password or the like may be requested.
  These passwords may be defined for each lock level, or may be common when making a transition to such a lock level.
[0037]
  Furthermore, you may have further the change means of the said correspondence table.
  Moreover, you may have a notification means to notify a user of the lock level memorize | stored in the said memory | storage means. For example, the notification unit may notify the user of information corresponding to the lock level as visual information.
[0038]
  Further, the information processing apparatus may include a unit that stores in advance predetermined information requested to be presented during WEB access, and a unit that presents the predetermined information to the server during the WEB access. In other words, when an input of a password or the like is required for accessing the homepage, the user selects a password stored in advance for the homepage and inputs the selected password or the like in the password input field of the homepage. You may have a means.
  Note that the mobile phone terminal may select a password or the like necessary for browsing the home page from among previously stored passwords and enter the password or the like in the password input field of the home page.
  Hereinafter, the mobile phone terminal will be described in detail with reference to FIG.
[0039]
  FIG. 1 is a diagram showing an internal configuration example of the mobile phone terminal. The mobile phone terminal 10 includes a control unit 1, a radio unit 2, an operation unit 3, and a storage unit 6. In addition, you may have the external I / F part 5, the display part 4, the speaker which is not shown in figure, LED, a vibrator, etc.
[0040]
  The radio unit 2 transmits and receives signals to and from the base station under the control of the control unit 1. That is, a wireless protocol is realized. For example, during a call operation, reception of incoming signals and transmission of outgoing signals are performed.
[0041]
  The operation unit 3 notifies the control unit 1 of various instructions from the user.
  The storage unit 6 stores at least a correspondence table between lock levels and functions to be locked and the current lock level of the terminal. In addition, the control unit 1 stores the various instructions notified from the operation unit 3.
[0042]
  The display unit 4 displays the state of the terminal and the like under the control of the control unit 1. For example, the control unit 1 may display the terminal state on the display unit 4 when instructed by the user to display the terminal state via the operation unit 3. As described above, information regarding the lock level may be displayed. As information about the lock level, for example, a name or a lock level number corresponding to the lock level can be used.
[0043]
  The LED lights up under the control of the control unit 1. In addition, when notifying the information regarding a lock level by LED, you may change LED which lights for every said lock level. Further, the blinking interval may be changed for each lock level. Further, the lock level may be notified by a combination thereof.
[0044]
  The external I / F 5 is connected to an external terminal such as a data communication device such as a personal computer or a PDA to exchange information.
[0045]
  The speaker emits a predetermined notification sound when the terminal receives an incoming call under the control of the control unit 1.
  The lock level may be notified to the user by a speaker. In other words, the user may be notified of the lock level by changing the sound, changing the interval of sound generation, or a combination thereof. Further, when the lock level is notified by the speaker as described above, the user may be notified for a predetermined time after instructing the operation unit 3 to notify the lock level.
[0046]
  The vibrator vibrates the terminal under the control of the control unit 1 when an incoming call is received at the terminal.
  In addition, you may make it notify a user of a lock level with a vibrator. Further, when the lock level is notified by the vibrator in this way, the user may be notified for a predetermined time after instructing the operation unit 3 to notify the lock level.
  Note that the notification of the lock level may be performed by any one of the display unit 4, the LED, the speaker, and the vibrator, or may be performed by a plurality.
  Hereinafter, the operation of the control unit 1 will be described.
[0047]
  Next, the lock level will be described. As described above, each lock level defines a function that prohibits, ie, locks, the user's use. The number of the lock levels can be arbitrarily set, but has a level at which at least all functions can be used. Also, a lock level corresponding to a conventional dial lock function or key lock function may be provided.
[0048]
  It should be noted that each lock level may specify a function that allows the user to use, that is, does not lock. In this case, the control unit 1 can determine the function to be locked in the same manner as described above by excluding the functions permitted to be used at each lock level from all the functions.
[0049]
  For example, the lock level can be set as follows.
(1)Level 0
  Level that prohibits the use of all functions. Level that realizes the so-called key lock state.
(2)Level 1
  Level that does not make a call. Level that realizes the so-called dial lock state.
(3)Level 2
  A level that only allows the use of voice communication, data communication, packet communication or multiple communication settings (line type setting) and manual settings (whether all settings are enabled or disabled).
(4)Level 3
  In addition to the contents of level 2, a level that enables communication to the external terminal 20 connected via the external I / F unit 5 (adapter connection is enabled and the PDA or personal computer connected to the external I / F unit 5 Level to allow communication).
(5)Level 4
  In addition to the contents of level 3, a level that permits the use of only a specific function (for example, a specific key such as manner mode setting that is set by pressing a key button of the operation unit 3 for a predetermined time or e-mail confirmation) Level that can set the function set by pressing).
(6)Level 5
  In addition to the contents of level 4, all functions are set, that is, the menu function is allowed to be used.
(7)Level 6
  In addition to the contents of level 5, the level that allows reference to internal data such as phone books and fixed phrases.
(8)Level 7
  In addition to the contents of level 6, this level allows changes to internal data such as phone books and fixed phrases.
(9)Level 8
  The level at which all functions can be used (the level without locking function). So-called normal level.
  This level setting example is merely an example. As described above, each lock level is set with a function that can be used (enabled) or a function that rejects use (disabled).
[0050]
  It should be noted that at any lock level, it is possible to change the lock state, that is, to release the lock state or change the level.
  In addition, incoming calls may be received at all lock levels.
[0051]
  The user may be able to change the lock level setting as described above from the operation unit 3. For example, the number of levels described above may be changed, the content of a function that restricts the use of each level may be changed, or the content may be changed together. .
  In addition, the user may select an example of the lock level stored in advance in the storage unit 6 from the operation unit 3, and cause the control unit 1 to set the lock level according to this lock level example.
[0052]
  When the control unit 1 is instructed by the user to change the lock level setting via the operation unit 3, the control unit 1 changes the lock level stored in the storage unit 6.
  Note that the control unit 1 may change the setting of the lock level based on an instruction from the user only when a predetermined requirement is satisfied. For example, the predetermined requirement may be that the terminal is in a specific lock level state.
[0053]
  An example of the lock level setting changing operation will be described more specifically with reference to FIG. FIG. 2 shows a display example of the display unit 4 when setting the lock level.
  As shown in FIG. 2, when the control unit 1 is instructed by the user to display a lock level setting screen on the display unit 4 via the operation unit 3, for example, a screen as shown in 30 is displayed on the display unit 4. To display. Based on the display screen 30, the user uses the operation unit 3 to select whether to change the setting as described above (whether to perform manual setting) or to perform level setting.
[0054]
  When the control unit 1 is instructed to perform manual setting, the control unit 1 starts the display unit 4 and sets whether to enable (enable) or disable (disable) each function (see FIG. 2 display screens 32, 33). Next, the user confirms whether or not to register the setting (display screen 35 in FIG. 2). When an instruction to register is received, the setting is registered. That is, the lock level setting is changed.
[0055]
  The user selects the lock level when the terminal is locked. For example, a lock level to be changed from the operation unit 3 is designated (display screen 36 in FIG. 2), and the control unit 1 is changed to this lock level (display screen 38 in FIG. 2). Alternatively, the control unit 1 may display information about each lock level on the display unit 4, and the lock level to be changed by the operation unit 3 may be designated based on this display.
[0056]
  The transition to level 0 or 1 in the above lock level example, so-called normal key lock state or dial lock state, may be instructed by an operation different from the transition to another lock level state.
  That is, as in the prior art, the operation unit 3 may be provided with a key for issuing a command to shift to the dial lock state or the key lock state to the control unit 1. In this case, the control unit 1 transitions to a dial lock state or a key lock state when the user presses this key. In addition, when there is a special key operation (for example, an operation of pressing a predetermined key for a predetermined time or more), the operation unit 3 may issue a command to shift to these states to the control unit 1.
  Thereby, the user can change the terminal to the key lock state or the dial lock state by performing the conventional operation in the operation unit 3.
[0057]
  Similarly, a transition instruction to a predetermined or arbitrary level among the lock levels can be notified to the control unit 1 by an operation on the operation unit 3 different from a transition instruction to another level. You may do it. That is, a special key for making a transition to these lock levels or a key operation may be provided.
[0058]
  When in the locked state, the control unit 1 determines whether the instruction from the user is an instruction to use a function permitted at the set lock level. If it is an instruction to use a permitted function, the instruction is determined to be valid, and if it is an instruction to use a function that is not permitted, the instruction is determined to be invalid.
[0059]
  When determining that the instruction is valid, the control unit 1 executes the instruction. If it is determined that the instruction is invalid, the instruction is rejected and not executed.
  If it is determined that the instruction is invalid, a transition to a level where the instruction can be performed may be performed.
  Alternatively, the lock state may be released and the normal state may be restored. That is, in the example of the lock level, the transition to level 8 may be made.
  Alternatively, the instruction may be temporarily changed to a level where the instruction can be executed, and the instruction may be returned to the original level (transition) after the instruction is executed.
  The transition of these lock levels will be described later.
[0060]
  An example of the operation of the mobile phone terminal during locking will be described with reference to FIGS. FIG. 3 shows a state transition of the mobile phone terminal to which the present invention is applied. The flowchart shown in FIG. 5 represents the operation during locking of the mobile phone terminal to which the present invention is applied.
  The control unit 1 is in a level setting lock state (locked) from the user by the operation unit 342When there is a key input(Step S500), Check if this entered action is valid(Step S501). That is, it is determined whether an operation instruction (key input) from the user uses a function permitted by the set lock level.
[0061]
  If the above action is valid(Step S501 / YES)The control unit 1 performs the input operation.(Step S502)After storing the settings made in this operation in the storage unit 6 (normal operation 40)(Step S503), Original lock state (level setting lock state42Return to(Step S504). That is, when the operation instruction is an instruction to use only a function permitted at the lock level, the control unit 1 executes this instruction. After executing this instruction, the level setting lock state42Wait at.
[0062]
  If the above instructions are invalid(Step S501 / NO)The control unit 1 is in the level setting locked state.42Wait(Step S504). That is, when the operation instruction is an instruction to use a function that is not permitted at the lock level, the control unit 1 does not execute the instruction.
[0063]
  When the above instruction is invalid, the control unit 1 may make a transition to a lock level at which this operation instruction can be executed. This lock level transition will be described later. After the transition to this lock level, the operation instruction is executed. Then, after executing this process, the transition may be made to the original lock level, or the transition may be made to stand by with the transitioned lock level.
[0064]
  Note that the lock level after the transition described above may be level 8 of the above lock level example, that is, the normal state 40.
[0065]
  Also, the level setting lock state42From the normal dial lock state 41, that is, the level 1 state of the above lock level example, and from the normal state 40, ie, the level 8 of the above lock level example, to the level setting lock state.42Normal dial lock state41It is assumed that transition to (level 1 above) is also possible.
  In addition, the normal dial lock state41When cancelingA transition to the normal state 40 may be made, or a transition to the level setting lock state 42 may be made.
  Hereinafter, the transition of the lock level state will be described in detail.
[0066]
  The control unit 1 determines whether or not the lock level change command from the user is an instruction to enable the function whose lock level currently set in the storage unit 6 is locked. That is, when a transition is made to the lock level specified by the lock level change command, it is determined whether or not the function currently locked can be used.
  In the above lock level example, it is determined whether the instruction is a transition instruction to a lower level number, i.e., a transition instruction to a level with less usage restrictions, or a transition instruction to a higher level number, i.e., a transition instruction to a level with more usage restrictions. To do.
[0067]
  In the case of a transition command to a level that increases usage restrictions, the control unit 1 transitions the state of the terminal to the commanded level based on this transition command. In other words, if the command is a change instruction to the lock level that does not allow the currently locked function to be used, the state transits to this lock level without any condition.
[0068]
  In the case of a transition command to a level with less usage restrictions, the user is made to input information for transitioning to this level. That is, in the case of a change instruction to a lock level that makes it possible to use a function that is currently locked, the user is caused to input information for transition to this level as a condition for this transition.
  This information may be determined for each lock level, or may be the same for all cases where a transition instruction to a level with less usage restrictions is executed.
[0069]
  For example, the control unit 1 may cause the user to input the same number as the predetermined password, or may allow the user to input the same password as the predetermined password. And the password may be input by the user. Further, other information may be input. For example, the same information as the predetermined information may be input via the external terminal 20.
[0070]
  FIG. 4 shows an example of a display screen of the display unit 4 in the case where the user inputs a personal identification number and a password in order to execute this transition command.
  The control unit 1 instructs the user to input a personal identification number via the display unit 4.
  The user inputs a password from the operation unit 3 (display screen 40).
  The control unit 1 determines whether this password is the same as a predetermined password. If it is determined that the passwords are the same, the user is instructed to input a password via the display unit 4 (display screen 41).
[0071]
  The user inputs a password through the operation unit 3 (display screen 42). Note that after the user finishes inputting the password, the control unit 1 may not display the password on the display unit 4 as in the display screen 43. Further, when the user inputs a password using the operation unit 3, the password may not be displayed as in the display screen 42, and for example, the password may not be displayed as in the display screen 43. Further, the password may not be displayed on the display unit 4.
[0072]
  The control unit 1 determines whether or not the password notified from the user matches a predetermined password. If they match, the lock state is transitioned based on the transition command (display screen 44).
  If the password or password does not match a predetermined one, the lock state is not changed and the process waits. Note that the user may be requested to input the information again.
[0073]
  The control unit 1 may not display a menu for executing a function locked in the set lock state on the display unit 4. Thereby, the user can easily grasp the usable functions.
[0074]
  Also,Using the function to store passwords and passwords in advance,You may make it input the password etc. of a homepage.
  Some homepages require the entry of predetermined information such as a password as a condition for browsing.
  However, since the size of the case of the mobile phone terminal is limited, there are cases where it is not possible to input a password or the like required on such a home page. That is, when it is necessary to input characters or the like, it is very difficult to access this home page from a mobile phone terminal having only numeric keys.
[0075]
  In particular, when entering a password, in order to prevent a person around the screen from knowing the password, it was impossible to access a home page without displaying the password on the screen.
  Currently, when inputting characters with the operation unit 3 of the mobile phone terminal, a plurality of characters are input with one numeric key (ten key) of the operation unit 3. For example, the character “A” is input by pressing the number key “1” once, and the character “O” is input by pressing the number key 5 times.
  However, if this character is not displayed on the screen, it is practically impossible to input the character. That is, the user can input a character even if the character is not displayed on the screen as described above when the character and the key correspond one-to-one like a keyboard. On the other hand, since the mobile phone terminal does not have a one-to-one correspondence between characters and keys, the user must determine whether the correct keyword has been input only by the number of times the key is pressed.

【The invention's effect】
  As is clear from the above description, according to the present invention, by providing a lock level, it is possible to set usable functions without returning to the normal state even in the locked state.
[0081]
  For example, when a mobile phone terminal is used only for data communication or used only for packet communication, it is possible to allow only the functions normally used and lock other functions. Become. That is, frequently used functions can be used, and functions that are used less frequently can be locked.
[0082]
  In other words, you can select functions that can be used even in the locked state, rather than disabling most of the functions uniformly, such as normal dial lock setting and key lock setting. Functions that are frequently used, such as changing the volume and referring to phone book data, can be used without releasing the lock state.
[0083]
  In addition, since it is possible to limit the functions to be used in this way, it is possible to lend a mobile phone terminal to an employee etc. after limiting the functions to be used, particularly in the case of a corporate contract. .
[0084]
  In addition, functions that are not contracted with a mobile phone station and cannot be used can be set in advance as invalid settings, and user convenience is improved.
[0085]
  Moreover, since it becomes possible to limit the function to be used, it becomes easy to lend a mobile phone terminal to others. That is, it is possible to set a lock state in which only functions that may be used by other people can be used. In particular, it is possible to lend a mobile phone terminal after making it impossible to refer to information relating to the user's private information such as telephone directory data and incoming call history.
[0086]
  Further, according to the present invention, it is possible to set a function that can be used (a function that cannot be used) by a simple operation of changing the lock level.
[0087]
  Further, according to the present invention, it is possible to browse a home page that requires input of a password or the like that has been difficult to browse from a mobile phone terminal.
