Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone terminal having a lock function, and more particularly, to a portable telephone terminal for setting a function usable by a user for each lock level.

[0002]

2. Description of the Related Art Conventionally, a portable telephone terminal has a function of locking a dial so that a person other than a user cannot use it (hereinafter referred to as a dial lock function) and a key lock function for preventing malfunction. Some have. The following is disclosed as a conventional technique relating to such a dial lock function and a key lock function.

[0003] For example, Japanese Patent No. 3012599 discloses a detecting means for detecting that no key operation is performed within a predetermined time after a key operation is completed in a power-on and on-hook state, Means for restricting the key operation and invalidating the key input when the detecting means detects that the key operation is not performed within the predetermined time; and specifying a predetermined value when the key input is invalid. Means for canceling the control of the key operation in response to pressing of a key, wherein the specific key has a pressing surface lower than the pressing surfaces of other keys installed on the same plane. A technique related to a telephone (mobile phone terminal) is disclosed.
According to this conventional technique, the key lock state can be released only by pressing the specific key, and the pressed surface of the key for releasing the key lock setting state is located at a position lower than the pressed surfaces of the other keys. Because it is installed, when storing,
It is possible to prevent the user from pressing the specific key unintentionally.

Japanese Patent No. 3022832 discloses that when a lock setting key provided outside is operated, a control unit of an external medium transmits a lock setting request signal, and a control unit of a portable telephone (portable telephone terminal) main body. Receiving the signal, the controller of the mobile phone body transmits an ID inquiry signal, and the controller of the external medium receives the signal within α hours after transmitting the lock setting request signal; The control unit of the external medium transmits an ID reply signal, the control unit of the mobile phone body receives the signal within β hours after transmitting the ID inquiry signal, and the control unit of the mobile phone body includes: Collating the IDs of the received ID reply signals and, if they match, setting a lock, and discloses a technique related to a dial lock method for a mobile phone using an external medium. Have been. According to this conventional technique, the lock is not set or released by the key operation of the mobile phone (mobile phone terminal) body, and the mobile phone (terminal) can be transmitted to a third party as long as the user holds the external medium. Can be extremely reduced.

Japanese Patent Laid-Open No. 2000-1887873 discloses a method for automatically operating 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. It is determined whether or not the call is from a number, and if the call is not from the designated number, an automatic response is performed,
In the case of reading from the designated number, the mobile phone waits for the input of the password, and in the case where the input password matches the password stored in the password memory, performs a preset automatic operation. The technology of the automatic operation method is disclosed. According to this conventional technology, when a call is made from a preset number, the mobile phone is left behind, lost,
In the case of theft, various operations such as locking, setting the answering machine mode, and displaying a designated message can be performed.

When the user changes the settings of the mobile communication terminal while the dial lock function or the key lock function (hereinafter, a function that limits the functions available to the user is referred to as a lock function) is operating. , The user unlocks these lock functions, changes the settings, performs dial lock settings or key lock settings (hereinafter, the settings that limit the functions used in this manner are referred to as lock settings). It is necessary to return to the dial lock state or the key lock state (hereinafter, the state in which the functions to be used are limited is referred to as a lock state).

[0007] As described above, the conventional portable telephone terminal is extremely inconvenient because it requires a great deal of labor for the user. For example, when only a small change in the setting is performed, the lock state is returned to the normal state from the lock state, and the normal state is returned to the lock state after the setting is completed, compared with the effort (number of key inputs and the time required for the setting) required for the change. Sometimes, the effort required is larger.

In particular, in recent years, portable telephone terminals have become multifunctional and are used not only as telephones but also for many services. As described above, as the position of the mobile phone terminal is no longer a mere contact item but an information terminal that stores a lot of information, the user often keeps the terminal in a locked state so as not to be used by others. .

[0009] However, with such multi-functionality, the frequency of use of the portable telephone terminal becomes higher than ever before. That is, since the user frequently uses the mobile phone terminal, the user must frequently perform the work of returning the terminal from the locked state to the normal state and returning the terminal to the locked state after use.

On the other hand, Japanese Patent Laid-Open Publication No. Hei 10-257170 discloses that when a specific password and a destination telephone number are input in a dial lock setting state, the dial lock setting state is released, and A first prior art related to a portable telephone terminal that makes a call to a destination telephone number and returns to a dial lock setting state when a telephone call ends is disclosed.

Japanese Patent Laying-Open No. 11-355432 discloses an operation for inputting a password for releasing the dial lock during dial lock setting, and a selection key for releasing the dial lock or a selection key for temporarily releasing the dial lock. A second conventional technique relating to a mobile communication terminal that releases dial lock by releasing or temporarily releasing the input operation when the input password is correct when the input operation is performed is disclosed.

[0012]

However, according to the first prior art, when making a dial call while in the dial lock setting state, it is sufficient to input the other party's telephone number after the specific password. In addition, when the call is ended, the state automatically returns to the dial lock setting state. However, no countermeasure is shown for using a function other than the call. In particular, since today's mobile phone terminals are increasingly used for functions other than telephones, it cannot be said that this first prior art shows any countermeasure against the above-mentioned problems. Not too much.

Further, according to the second prior art, it is possible to select whether to release the dial lock setting or to temporarily release the dial lock setting. Is done. In addition, since the method of releasing the dial lock setting must be determined before releasing, if you select temporary release and perform the operation, if you need to perform further operations, release the lock setting again. It must be made.

Note that the mobile phone terminal may select a password or the like necessary for browsing the homepage from passwords or the like stored in advance, and input this password or the like in the password or the like input field of the homepage. Hereinafter, this mobile phone terminal will be described in detail with reference to FIG.

FIG. 1 is a diagram showing an example of an internal configuration of the portable telephone terminal. The mobile phone terminal 10 includes a control unit 1, a wireless unit 2, an operation unit 3, and a storage unit 6. In addition,
External I / F 5, display 4, speaker (not shown), LE
D, a vibrator or the like may be provided.

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 an incoming signal, transmission of an outgoing signal, and the like are performed.

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 a lock level and a function to be locked, and a current lock level of the terminal. Also, the control unit 1 operates the operation unit 3
The above-mentioned various instructions notified from are stored.

The display unit 4 displays the status of the terminal and the like under the control of the control unit 1. For example, when the user instructs to display the state of the terminal via the operation unit 3, the control unit 1 may display the state of the terminal on the display unit 4. As described above, information regarding the lock level may be displayed. The information on the lock level may be, for example, a name or a lock level number corresponding to the lock level.

The LED lights up under the control of the control unit 1.
When the information about the lock level is notified by the LED, the LED that is turned on for each lock level may be changed. Further, the blinking interval may be changed for each lock level. Also, the lock level may be notified by a combination of these.

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.

The speaker emits a predetermined notification sound under the control of the control unit 1 when there is an incoming call to the terminal. In addition,
The user may be notified of the lock level by a speaker. That is, the user may be notified of the lock level by changing the sound, changing the interval at which the sound is emitted, or combining them. When the lock level is notified by the speaker as described above, the notification may be performed for a predetermined time after the user instructs the operation unit 3 to notify the lock level.

The vibrator vibrates the terminal under the control of the control unit 1 when there is an incoming call to the terminal. In addition,
The user may be notified of the lock level by a vibrator. When the lock level is notified by the vibrator as described above, the notification may be performed for a predetermined time after the user instructs the operation unit 3 to notify the lock level. Note that the notification of the lock level may be made by only one of the display unit 4, the LED, the speaker, and the vibrator, or may be made by a plurality. Hereinafter, the operation of the control unit 1 will be described.

Next, the lock level will be described. As described above, each lock level prohibits the use of the user, that is, defines the function of locking. The number of lock levels can be set arbitrarily, but has at least a level that enables all functions. Further, a lock level corresponding to a conventional dial lock function or key lock function may be provided.

It should be noted that each lock level may define a function that permits the user to use the lock level, that is, a function that does not lock. In this case, the control unit 1
The function to be locked can be determined in the same manner as described above by excluding the functions permitted to be used at each lock level from all the functions.

As an example of setting the lock level, for example,
It can be set as follows: Level 0 Level at which use of all functions is prohibited. A level that realizes the so-called key lock state. Level 1 Level that does not allow calls. A level that achieves the so-called dial lock state. Level 2 Permits the use of only one of voice communication, data communication, and packet communication (line type setting) and manual setting (setting whether all settings are enabled or disabled). level. Level 3 In addition to the contents of Level 2, a level at which the external terminal 20 connected via the external I / F unit 5 performs communication (with the adapter connection enabled and a PDA or personal computer connected to the external I / F unit 5). Level to allow communication). Level 4 In addition to the contents of Level 3, a level at which use of a specific function is permitted (for example, a specific mode such as a manner mode setting which is set by pressing a key button of the operation unit 3 for a predetermined time or more, a mail confirmation, etc.) Level at which the function set by pressing the key can be set). Level 5 In addition to the contents of Level 4, all function settings are made, that is, the levels that allow the use of menu functions. Level 6 In addition to the contents of Level 5, a level that allows reference to internal data such as telephone directories and fixed phrases. Level 7 In addition to the contents of Level 6, a level that allows changes to internal data such as telephone directories and fixed phrases. Level 8 Level at which all functions can be used (level with no lock function). The so-called normal state level. Note that this level setting example is merely an example. As described above, a function that can be used (validated) or a function that rejects use (validated) is set for each lock level.

It is to be noted that, at any lock level, the transition of the lock state, that is, the release of the lock state and the change of the level can be performed. In addition, an incoming call may be received at all lock levels.

The user may be able to change the lock level setting from the operation unit 3 as described above. For example, the number of levels described above may be changed, the content of the 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 the storage unit 6 in advance from the operation unit 3 and cause the control unit 1 to set the lock level according to the lock level example.

The control section 1 changes the lock level stored in the storage section 6 when instructed by the user to change the lock level setting via the operation section 3. 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.

An example of this lock level setting change operation is as follows.
This will be described more specifically with reference to FIG. FIG.
4 shows a display example of the display unit 4 when setting a 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, the control unit 1 displays, for example, a screen 30 as shown in FIG. To be displayed. Based on the display screen 30, the user selects whether to change the setting as described above (to perform manual setting), to perform level setting, or to use the operation unit 3.

When instructed to perform manual setting, the control unit 1 starts the display unit 4 and sets whether to enable (enable) or not (disable) for each function. (Display screens 32 and 33 in FIG. 2). 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 setting of the lock level is changed.

When the user locks the terminal,
Select the above lock level. For example, a lock level to which a transition is made from the operation unit 3 is specified (display screen 36 in FIG. 2),
The control unit 1 makes the transition to this lock level (display screen 38 in FIG. 2). Alternatively, the control unit 1 may display information related to each lock level on the display unit 4 and, based on the display, may specify a lock level to be shifted by the operation unit 3.

The transition to the level 0 or 1 in the above lock level example, that is, the so-called normal key lock state or dial lock state, may be instructed by an operation different from the transition to other lock level states. Good. That is, similarly to the related art, the operation unit 3 may be provided with a key that issues a command to the control unit 1 to shift to the dial lock state or the key lock state. In this case, when the user presses this key, the control unit 1 transitions to the dial lock state or the key lock state. Further, when a special key operation (for example, an operation of pressing a predetermined key for a predetermined time or more) has been performed, the operation unit 3 may issue a command to the control unit 1 to shift to these states. This allows the user to
By performing the conventional operation on the operation unit 3, the terminal can be shifted to the key lock state or the dial lock state.

Similarly, among the lock levels,
A transition instruction to a predetermined or arbitrary level may be notified to the control unit 1 by an operation on the operation unit 3 different from a transition instruction to another level. That is, a special key for shifting to these lock levels may be provided, or a key operation may be provided.

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 the instruction is to use a permitted function, the instruction is determined to be valid. If the instruction is to use a function that is not permitted, the instruction is determined to be invalid.

If the control unit 1 determines that the instruction is valid, it executes the instruction. If the instruction is determined to be invalid, the instruction is rejected and not executed. If it is determined that the instruction is invalid, a transition to a level at which the instruction can be executed may be performed. Alternatively, the locked state may be released, and the state may be returned to the normal state. That is, in the example of the lock level described above, a transition to level 8 may be made. Alternatively, the instruction may be temporarily shifted to a level at which the instruction can be executed, and after executing the instruction, the level may return to the original level (transition). The transition of these lock levels will be described later.

Referring to FIG. 3, an example of the operation of the portable telephone terminal during locking will be described. When there is a key input from the user in the level setting lock state (locked) 43 on the operation unit 3, the control unit 1 checks whether the input operation is valid. That is, it is determined whether the operation instruction (key input) from the user is to use a function permitted at the set lock level.

When the above operation is valid, the control unit 1
The input operation is performed, the setting made by this operation is stored in the storage unit 6 (normal operation 40), and then the operation returns to the original lock state (level setting lock state 43). That is, when the operation instruction is an instruction to use only the function permitted at the lock level, the control unit 1 executes this instruction. After executing this instruction, the apparatus stands by in the level setting lock state 43.

When the instruction is invalid, the control unit 1 waits in the level setting lock state 43. That is,
If the operation instruction is an instruction to use a function not permitted by the lock level, the control unit 1 does not execute the instruction.

When the above instruction is invalid, the control unit 1
May transition to a lock level at which this operation instruction can be executed. The transition of the lock level will be described later. After the transition to the lock level, the operation instruction is executed. After the execution of this process, the lock level may be changed to the original lock level, or the lock level may be changed to the standby state.

The lock level after the above transition is
Level 8 of the above lock level example, that is, normal state 4
It may be set to 0.

It is assumed that the state can be shifted from the level setting lock state 43 to the normal dial lock state 41, that is, the state of level 1 of the above-described lock level example. It is assumed that a transition can be made to the level setting lock state and the normal dial lock state 42 (level 1 above). When releasing the normal dial lock state 42,
The state may be changed to the normal state 40 (42 / N
O), a transition to the level setting lock state 43 may be made (42 / YES). Hereinafter, the transition of the lock level state will be described in detail.

The control unit 1 determines whether or not the lock level change command from the user is an instruction to enable the function locked by the lock level currently set in the storage unit 6. That is, when a transition is made to the lock level instructed by the lock level change command, it is determined whether or not the currently locked function is enabled. In the above lock level example, it is determined whether a transition instruction to a lower number of levels, that is, a transition instruction to a level with a smaller use restriction, or a transition instruction to a higher number of levels, that is, a transition instruction to a level with a larger use restriction. I do.

If the command is a transition command to a level that increases the use restriction, the control unit 1 transitions the state of the terminal to the commanded level based on the transition command. In other words, if the instruction is a change instruction to a lock level that does not make the currently locked function usable, the state transits to this lock level without any condition.

In the case of a transition command to a level at which the use restriction is further reduced, the user is required to input information for transitioning to this level. That is, in the case of a change instruction to a lock level that makes the currently locked function usable, the user is required 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 information when executing a transition instruction to a level that further reduces the use restriction.

The control unit 1 may allow the user to input the same password as a predetermined password, or may cause the user to input the same password as a predetermined password. Alternatively, the user may input the number and the password. Also,
Other information may be input. For example, the same information as predetermined information may be input via the external terminal 20.

FIG. 4 shows an example of a display screen of the display unit 4 when the user inputs a password and a password in order to execute the transition command. The control unit 1 instructs the user to input a password through the display unit 4. The user inputs a password through 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 via the display unit 4 to input a password (display screen 4).
1).

The user inputs a password using the operation unit 3 (display screen 42). After the user has finished 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 the password using the operation unit 3, the password may not be displayed as in the display screen 42, and the password may not be displayed as in the display screen 43, for example. Also, the password may not be displayed on the display unit 4.

The control section 1 determines whether the password notified by the user matches a predetermined password. When they match, the lock state is transited based on the transition instruction (display screen 44). If the above password or PIN does not match the predetermined one,
Waits without changing the lock state. The user may be required to input the above information again.

The control unit 1 may not display a menu for executing the function locked in the set lock state on the display unit 4. As a result, the user can easily grasp the usable functions.

Also, using the password input function,
You may make it input a password etc. of a homepage. Some homepages require entry of predetermined information such as a password as a condition for browsing.
However, since the size of the housing of the mobile phone terminal is limited, it may not be possible to input a password or the like required on such a homepage. That is, when it is necessary to input characters and the like, it is very difficult to access this home page from a mobile phone terminal having only numeric keys.

In particular, when entering a password, no one can access a home page that does not display the password on the screen at all, in order to prevent anyone around the screen from knowing the password. At present, when performing character input using the operation unit 3 of the mobile phone terminal, a plurality of characters are input using one numeric key (numeric keypad) of the operation unit 3.
For example, the character "A" is input by pressing the numeric key "1" once, and the character "O" is input by pressing the key five times. However, if this character is not displayed on the screen, it is practically impossible to input the character. That is, when a character and a key have a one-to-one correspondence like a keyboard, the user can input a character even if the character is not displayed on the screen. On the other hand, in the mobile phone terminal, since characters and keys do not correspond one-to-one, it is necessary for the user to determine whether a correct keyword has been input only by the number of times the key is pressed.

Therefore, the control unit 1 stores in advance information such as a password required to be input on such a homepage, and inputs this information in an input field for a password or the like. First, using the password input function, the user inputs information such as a password for a homepage required to input a personal identification number and a password from the operation unit 3. The control unit 1 stores the password in the storage unit 3. This password and the like are stored for each homepage. Note that the input may be made from the external terminal 20 connected to the external I / F unit 5.

When the control unit 1 determines that the home page requires a password input, the control unit 1 waits for the user to be instructed which of the passwords and the like stored in the storage unit 3 is to be used. That is, the password and the like are displayed on the display unit 4 and the user is made to select from the operation unit 3. When the homepage is determined by the user, the user may instruct the control unit 1 via the operation unit 3 to display the password or the like on the display unit 4.

When a password or the like to be input is selected, the control unit 1 inputs the password or the like into the password or the like input field of the homepage.

When the input of the information such as the password is requested, the information such as the password may be created in the mobile phone terminal 10 and the information may be input in the input box. That is, instead of using a password or the like stored in advance, it may be created when requested. In such a case, as shown in FIG.
Characters may be displayed on the display unit 4 and a password may be created while allowing the user to confirm whether a correct password has been input.

[0078]

As is apparent from the above description, according to the present invention, by providing a lock level, it is possible to set functions that can be used without returning to the normal state even in the locked state. Becomes

For example, when the mobile phone terminal is used only for data communication or when it is used only for packet communication, only the normally used functions are permitted and other functions are locked. Becomes possible. That is, it is possible to enable frequently used functions and to lock functions that are used less frequently.

That is, unlike the normal dial lock setting and key lock setting, most of the functions are not uniformly disabled, but a function that can be used even in the locked state can be selected. Therefore, frequently used functions such as changing the ring volume and referring to the phonebook data can be used without releasing the locked state.

In addition, since it is possible to limit the functions to be used, it is possible to lend a mobile phone terminal to an employee or the like after limiting the functions to be used, especially in the case of a corporate contract. It becomes possible.

Further, it is possible to previously invalidate functions that are not contracted with the mobile telephone station and cannot be used, thereby improving the usability of the user.
