The CPU 11 controls the mobile communication terminal 10
It is for controlling the operation of each part of 0 and the whole.
The CPU 11 locks or unlocks various functions of the mobile communication terminal device 100 according to the instruction information input by the input keys 7. On this occasion,
When the CPU 11 locks various functions provided in the mobile communication terminal device 100, except for the case where instruction information for releasing the lock is input by the input key 7,
The instruction information and data information sent from the input key 7 are invalidated. For example, when a specific key included in the input key 7 is continuously depressed for one second or more in a state where the lock is not locked, various functions of the mobile communication terminal device 100 are locked and the key is locked. It is locked. On the other hand, when a specific key included in the input key 7 is continuously pressed for one second or more in the key locked state, the CPU 11 releases the lock and performs processing according to instruction information and data information from the input key 7. Can be executed.

When the CPU 11 receives the short mail sent from the partner terminal in the key lock state, the CPU 11 temporarily releases the lock. That is, when receiving the short mail, the CPU 11 receives the instruction information sent from the input key 7 and enables, for example, a process for browsing the short mail. Here, the CPU 11 substantially includes a timer 20 for specifying the timing of re-locking the released lock.

The timer 20 is realized, for example, by the CPU 11 executing a predetermined processing program, and measures the elapsed time from the timing when the mobile communication terminal device 100 receives the short mail. Timer 2
When the mobile communication terminal device 100 unlocks the lock due to the reception of the short mail, it resets the measured elapsed time and starts (restarts) the measurement of the elapsed time again.

Further, according to the instruction information sent from the input key 7, the CPU 11 preliminarily releases unlocking time information and locking time information for specifying the timing of re-locking when a character message is received and unlocked. It is created and stored in the nonvolatile memory 5.

The operation of mobile communication terminal 100 according to the embodiment of the present invention will be described below. The mobile communication terminal device 100 automatically unlocks when receiving a text message, for example, a short mail, and automatically locks again when there is no key operation or when the standby state continues for a certain period of time. It is a device that can be locked or unlocked appropriately in response to receiving a short mail.

The CPU 11 controls the mobile communication terminal 10
When the instruction information for operating the key lock function is input from the input key 7 while the power is turned on to 0,
Thereafter, the instruction information and data information input from the input key 7 are invalidated and locked to various functions provided by the mobile communication terminal device 100 (for example, a transmission function by pressing a dial key, a telephone directory browsing / registering function, and the like). multiply.

Here, when the mobile communication terminal device 100 receives the short mail and automatically releases the lock, the CPU 11 executes the release time information and the lock time information for specifying the timing of re-locking. Are created in advance and stored in the nonvolatile memory 5. Note that the release time information is information indicating the time from the timing when the mobile phone device 100 receives the short mail and releases the lock to the timing when the lock is reset when there is no key operation. After the mobile phone device 100 receives the short mail and unlocks the lock, the CPU 11 executes the processing according to the instruction information sent from the input key 7, and the processing ends. Mobile telephone device 1
This is information indicating the time from the timing at which 00 is set to the standby state to the timing at which locking is performed again when there is no key operation.

For example, in the unlocked state, the CPU 11 displays a screen for performing settings related to the key lock function as shown in FIG. 2A in accordance with the instruction information sent from the input key 7. 8 is displayed. The user operates the input key 7 to move the cursor CS1 to set whether to automatically lock or release the lock.

At this time, the user, for example,
To the item "ON" shown in FIG.
The user presses an enter key (not shown) provided in. Thereby, the user automatically releases the lock when the mobile communication terminal device 100 receives the short mail, and locks again when there is no key operation until a predetermined time elapses. The operation of the mobile communication terminal device 100 can be set.

On the screen shown in FIG. 2A, the item "ON"
Is designated, the CPU 11 causes the display 8 to display a screen for creating release time information and lock time information as shown in FIG. 2B, for example.

The user operates the input key 7 to move the cursor CS2, and instructs creation of either the release time information or the lock time information. Here, the user is shown in FIG.
By selecting the item "Release time" shown in (b),
Creation of release time information can be instructed. On the other hand, the user can instruct creation of the lock time information by selecting the item “set time” shown in FIG.

At this time, when the creation of the release time information is instructed by the input key 7, the CPU 11 executes, for example, FIG.
Is displayed on the display unit 8, and information for specifying the timing of re-locking is acquired. Here, the user specifies the time from the timing when the mobile communication terminal device 100 receives the short mail to unlock the lock after receiving the short mail to the time when the lock is re-locked. You can specify when to lock.

For example, the user designates a number to be inputted at the position of the cursor CS3 by depressing a number key (not shown) provided on the input key 7, and designates a time, and a decision key (not shown) ) Is pressed to confirm the time designation. The CPU 11 creates release time information based on the acquired information and stores the information in the nonvolatile memory 5.

On the other hand, while the screen shown in FIG. 2B is being displayed on the display unit 8, when the creation of the lock time information is instructed by the input key 7, the CPU 11 executes, for example, the process shown in FIG.
Is displayed on the display unit 8 as shown in FIG. Here, the user releases the lock by receiving the short mail by the mobile communication terminal device 100, ends the process according to the instruction information from the input key 7, and starts the lock from the timing when the mobile communication terminal device 100 enters the standby state. By designating the time until the re-calling timing, it is possible to specify the timing for automatically re-locking after the mobile telephone device 100 enters the standby state. The standby state of the mobile communication terminal apparatus 100 is a state in which the CPU 11 executes a variety of programs such as a processing program for viewing a short mail and activates various functions, for example, except for a state in which the user operates a key. No power is on.

The user designates a time by, for example, pressing a number key (not shown) provided in the input key 7 and designating a number to be inputted at the position of the cursor CS4, and pressing a decision key (not shown). By doing so, the designation of the time is determined. The CPU 11 creates locking time information based on the acquired information and stores the information in the nonvolatile memory 5.

In this manner, the unlock time information and the lock time information are stored in the non-volatile memory 5, and the mobile communication terminal device 100 in the key lock state according to the instruction information from the input key 7.
The CPU 11 performs communication by transmitting and receiving wireless signals to and from base stations constituting a mobile communication network by controlling the operations of the RF signal processing circuit 2 and the baseband signal processing circuit 3 by the CPU 11. If the release time information and the lock time information by the user's key operation are not created, C
The PU 11 may execute the following processing using the default release time information and the lock time information stored in the ROM (not shown) included in the nonvolatile memory 5.

When receiving a call originated from the partner terminal (or mail transmitting organization), CPU 11 reads an information element indicating the destination subaddress and an information element indicating the transmission capability included in the call setting message. Based on the result of reading the information element, the CPU 11 determines whether the call originating from the partner terminal (or the mail transmitting organization) is a request for a telephone call or a request for distribution of a short mail. Determine.

When the CPU 11 determines that the call originated from the partner terminal is a request for a call, the CPU 11 outputs a ring tone to a sounder (not shown) to release a lock, etc. Execute the processing to be performed.

[0054] On the other hand, the CPU 11
If it is determined that the call originated from the mail transmitting organization) is a request for short mail distribution, a normal short message such as displaying an image for notifying the user that the short mail has been received and outputting a ringtone is output. Execute the process for receiving mail.

Further, at this time, the CPU 11 executes a lock function control process shown in the flowchart of FIG.

When the lock function control process is started, the CPU
11 automatically releases the lock in response to the reception of the short mail, and effectively receives the instruction information sent from the input key 7 (step S1). Thereby, the CPU 11
The mobile communication terminal device 100 executes the processing program for browsing and transmitting the short mail according to the instruction information sent from the input key 7, for example.
Enables various functions provided by and automatically releases the key lock state.

At this time, the CPU 11 starts measuring the elapsed time by the timer 20, and the mobile communication terminal 10
0 measures the time that has elapsed since the short mail was received (step S2).

The CPU 11 monitors the elapsed time measured by the timer 20 and matches the elapsed time (release time) indicated by the release time information stored in the nonvolatile memory 5 with the timing of re-locking. It is determined whether or not this is the case (step S3).

When the CPU 11 determines that the elapsed time does not coincide with the release time (NO in step S3), the CPU 11 determines whether or not instruction information has been input through the input key 7, that is, whether or not a key operation has been performed (step S3). Step S4). C
If the PU 11 determines that there is no key operation (Step S
(NO in 4), the process returns to step S3, and it is determined whether or not the elapsed time matches the release time.

Here, when the CPU 11 determines that the elapsed time coincides with the release time (YE in step S3).
S), the various functions are locked and the instruction information sent from the input key 7 is invalidated (step S5), and the lock function control processing ends. That is, after receiving the short mail and releasing the lock, when the timing specified by the time indicated in the release time information arrives without any key operation, the CPU 11 locks the various functions of the mobile telephone device 100. In this case, the instruction information sent from the input key 7 is invalidated. However, when the instruction information to release the lock is sent from the input key 7, such as when the key for releasing the lock of the input key 7 is continuously pressed for a predetermined time, , CPU
11 receives this effectively.

If the CPU 11 determines in step S4 that a key operation has been performed (Y in step S4).
ES), the measurement of the elapsed time by the timer 20 is stopped (step S6). Thereafter, the CPU 11 reads from the nonvolatile memory 5 and executes a processing program for operating various functions such as a processing program for browsing and transmitting short mail, for example, in accordance with the instruction information sent from the input key 7. (Step S7).
Upon ending the processing according to the key operation, the CPU 11 puts the mobile telephone device 100 into a standby state (step S
8), the elapsed time measured by the timer 20 is reset and the measurement of the elapsed time is started (restarted) again (step S9).

The CPU 11 determines whether or not the time measured by the timer 20 matches the time (locking time) indicating the timing of re-locking indicated by the locking time information stored in the non-volatile memory 5 (locking time). Step S
10).

When the CPU 11 determines that the elapsed time does not coincide with the locking time (NO in step S10), the CPU 11 determines whether or not instruction information has been input through the input key 7, ie,
It is determined whether or not a key operation has been performed (step S1).
1). When determining that there is no key operation (NO in step S11), CPU 11 returns the process to step S10, and determines whether the elapsed time matches the release time.

On the other hand, if the CPU 11 determines that a key operation has been performed (YES in step S11), the process returns to step S6 to stop the timer 20, and
Executes processing according to key operation.

Further, the CPU 11 determines in the step S10
If it is determined that the elapsed time coincides with the locking time (YES in step S10), the process proceeds to step S5 to lock, and the lock function control process ends.

For example, when the screen shown in FIG. 2C is displayed on the display unit 8, the user receives only a short mail from the mobile communication terminal 100 and releases the lock for only 20 seconds from the timing when the lock is released. It is assumed that the time is specified so that the lock is reset when no key operation is performed.
Further, when the screen shown in FIG. 2D is displayed on the display unit 8, the user receives the short mail to unlock the mobile communication terminal device 100, and unlocks the lock. After executing the processing according to the instruction information,
It is assumed that the time is specified so that the lock is reset when the standby state continues for 45 seconds.

The CPU 11 sets the time (20 seconds) specified when the screen shown in FIG. 2C is displayed on the display 8.
Is generated and stored in the non-volatile memory 5. Further, the CPU 11 creates locking time information for specifying a specified time (45 seconds) when the screen shown in FIG. 2D is displayed on the display unit 8 and stores the locking time information in the nonvolatile memory 5. .

When the CPU 11 locks various functions of the mobile communication terminal 100 according to the instruction information sent from the input key 7, and determines that a call requesting short mail distribution has been received, The lock is released, and the instruction information from the input key 7 is effectively received (step S1 in FIG. 3). At this time, the CPU 11 starts measuring the elapsed time by the timer 20 (Step S in FIG. 3).
2) Upon detecting that the elapsed time from the timing of receiving the short mail coincides with the time (20 seconds) specified by the release time information (Y in step S3 in FIG. 3).
ES), the lock is again applied, and the instruction information from the input key 7 is invalidated (step S5 in FIG. 3). On the other hand, CP
If U11 receives the instruction information from the input key 7 before the elapsed time matches the time (20 seconds) specified by the release time information (YES in step S4 of FIG. 3), the timer 20 measures the time. Is stopped (step S6 in FIG. 3), and processing according to the key operation is executed (step S7 in FIG. 3). The CPU 11 reads a processing program according to the instruction information received from the input key 7 from the non-volatile memory 5 and executes the processing program, and resets the timer 20 each time the processing ends and the apparatus enters a standby state (step S8 in FIG. 3). Start (step S9 in FIG. 3).

At this time, the CPU 11 monitors the timer 20 and continues the standby state for the time (45 seconds) specified by the lock time information (step S10 in FIG. 3).
YES), re-lock, and invalidate the instruction information sent from input key 7 (step S in FIG. 3).
5).

As described above, according to the present invention,
When a short mail is received in the key locked state, the lock is automatically released and processing according to the key operation can be executed. In addition, after unlocking in response to receiving a short mail, if there is no key operation, or if the standby state continues after performing the processing according to the key operation, the lock can be automatically re-locked. it can. This eliminates the need for key operation to unlock or redial when a short mail is received in a key-locked state, and unlocks or locks appropriately when a short mail is received. You can fix it.

The timing of re-locking when a short mail is received and the lock is released can be specified by the user using the input key 7, and the lock is appropriately applied in response to the reception of the short mail. , Or can be canceled.

The present invention is not limited to the above embodiment, and various modifications and applications are possible. For example, in the above embodiment, the mobile communication terminal device 100 has been described as receiving a short mail and automatically unlocking it. However, the present invention is not limited to this. The lock may be released.

Further, for example, in the above-described embodiment, the mobile communication terminal device 100 has been described as being a mobile telephone device represented by a PHS. However, the present invention is not limited to this. For example, a pager or a PDA (Personal Digital Assistants) may be used. The present invention can also be applied to a mobile terminal having a lock function and a text message transmitting / receiving function.

Further, in the above-described embodiment, the mobile communication terminal device 100 has been described as having a key lock function for locking in response to pressing of a key for locking, but the present invention is not limited to this. The present invention can also be applied to a lock function such as a dial lock which locks according to a password input by the key 7.

Further, in the above embodiment, the CPU 11
Performs a process in accordance with the instruction information sent from the input key 7 when a key operation is performed after receiving the short mail and unlocking the lock, enters a standby state after the execution, and indicates the lock time information. It has been described that the locking is performed again after the elapse of the locking time, but the present invention is not limited to this.
