Abstract

PROBLEM TO BE SOLVED: To provide a mobile phone terminal that can flexibly set a speech available time and can set the speech available time without intervention of a mobile phone enterprise even after the speech available time expires. SOLUTION: When a user makes dialing, a speech available time limit section 20 informs the user about disabled dialing and terminates the processing when contents of a memory A21 are smaller than contents of a memory B22. When the contents of the memory A21 are greater than the contents of the memory B22, since the speech available time limit section 20 informs the user about it, a control section 11 makes dialing to a destination to set a speech state. Since no interruption request is received and the control section 11 keeps the speech state, when a unit time expires, the speech available time limit section 20 adds the unit time to the memory B22, and when the contents of the memory A21 are equal to the contents of the memory B22, the speech available time limit section 20 informs the control section 11 about it to interrupt the speech.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone terminal and a method for restricting a callable time used therefor, and more particularly to a method for restricting use when a user who pays for a call differs from a user who actually uses the telephone.

[0002]

2. Description of the Related Art Conventionally, a mobile phone terminal has been used by a user who pays for a call (hereinafter referred to as an administrator).
In many cases, the actual user (hereinafter, referred to as a user) is not the same.

For example, when a parent buys a mobile phone to a child, there is a situation in which the child makes a long-term call without the parent's knowledge and pays a higher-than-expected amount when the call fee is paid. .

[0004]

In the above-mentioned conventional portable telephone terminal, when the manager and the user are different, it may be necessary to pay an unexpectedly high price at the stage of paying the call charge. At present, prepaid mobile phone terminals with prepaid call charges are also on sale, and it is possible to avoid the above situation, but users cannot set flexible outgoing call available time There is a problem.

[0005] Another problem is that even if it is desired to use a prepaid type mobile phone terminal after the expiration of the outgoing callable time, it must be re-enabled by a mobile phone operator.

Accordingly, an object of the present invention is to solve the above-mentioned problems, to enable flexible setting of a talkable time, and to allow a talkable time without going through a mobile phone carrier even after the talkable time has expired. It is an object of the present invention to provide a mobile phone terminal capable of setting a communication time and a method for limiting a callable time used therefor.

[0007]

A portable telephone terminal according to the present invention has a first function of storing a call available time set from outside.
, A second storage means for storing the accumulated call time of the call, a determination means for determining whether or not a password input from the outside is correct, and the determination means determines that the password is correct Writing means for writing to the first storage means and the second storage means when the call is made, and when the contents of the first storage means and the contents of the second storage means match, the call is made. And call disabling means for disabling the call.

[0008] A method for limiting the talkable time of a portable telephone terminal according to the present invention comprises the steps of judging whether or not an externally input password is correct, and setting the talkable time which is externally set when the password is determined to be correct. Writing to the first storage means for storing the time and the second storage means for storing the accumulated call time for which the call has been made; and the storage contents of the first storage means and the second storage means. Disabling the call when the stored contents match.

That is, the portable telephone terminal of the present invention allows a user who pays a call charge (hereinafter referred to as an administrator) to freely set a talkable time protected by a password, so that the user does not know the password and actually uses the password. The present invention provides a function capable of monitoring and limiting the accumulated call time of a user (hereinafter, referred to as a user).

[0010] In addition, when an available time is set, an administrator can set an arbitrary expiration date. When the expiration date has passed, the accumulated call time is automatically reset. Even if the accumulated call time becomes longer than the callable time and the call cannot be made, the call can be automatically made after the expiration date.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a mobile phone terminal according to one embodiment of the present invention. In FIG. 1, a mobile phone terminal 1 includes an antenna 11 and a control unit 12.
, A radio unit 13 and a ROM (read only memory) 14
, RAM (random access memory) 15, display unit 16, microphone 17, speaker 18, operation button 1
9 and a talk time limiter 20.

[0012] The memory A 21
, A memory B22, a memory C23, and a memory D24. The memory A21 has a talkable time storage area (unit: seconds) set by a user who pays the call (hereinafter, referred to as an administrator), and a memory B22. Is an integrated call time storage area (unit: second) in which a user who actually uses (hereinafter, referred to as a user) made an outgoing call, a memory C23 is an expiration date unused flag, and a memory D24 is an expiration date storage area (unit). : Days).

FIGS. 2 and 3 are flow charts showing a process for setting a possible outgoing call time and an expiration date of the portable telephone terminal 1 according to one embodiment of the present invention, and FIG. 4 is a flowchart showing the portable telephone terminal 1 according to one embodiment of the present invention. FIG. 5 is a flowchart showing an expiration date check process automatically performed every day by the mobile phone terminal 1 according to an embodiment of the present invention. The processing operation of the mobile phone 1 according to one embodiment of the present invention will be described with reference to FIGS.

As a precondition, only the administrator knows the password of the mobile phone terminal 1 according to one embodiment of the present invention, and the password has been set in the mobile phone terminal 1 before setting the outgoing call available time. It is assumed that

First, when the administrator sets the outgoing call available time and the expiration date in the mobile phone terminal 1, the outgoing call available time and the expiration date setting process are performed. The mobile phone terminal 1
Is passed to the user, and when the user actually makes the outgoing call, the integrated outgoing call time monitoring process is performed.

Talk time limit unit 20 of portable telephone terminal 1
When a request to start setting of the outgoing call possible time is sent from the administrator (step S1 in FIG. 2), a request for input of a password is made to the administrator (step S2 in FIG. 2). When a password is input from the administrator (step S3 in FIG. 2), the available call time limiter 20 determines whether the password is correct (step S4 in FIG. 2).

If the password is not correct, the available call time limiter 20 returns to step S2 and again requests the administrator to input the password. If the password is correct, the available call time limit unit 20 requests the manager to input the available call time (step S5 in FIG. 2).

When the outgoing call available time is inputted by the manager (step S6 in FIG. 2), the available call time limiter 20 receives the input.
The outgoing call available time is written into the memory A21 (step S7 in FIG. 2), and “0” is written into the memory B22 (step S8 in FIG. 2). Thereafter, the available call time limiter 20 requests the administrator to input whether or not an expiration date has been set (step S9 in FIG. 3). When the administrator inputs the setting whether or not the expiration date has been set (step S10 in FIG. 3), It is determined whether an expiration date is set (step S11 in FIG. 3).

If there is no expiration date set, the available call time limiter 20 sets OFF in the memory C23 and ends the outgoing call available time and expiration date setting process (step S12 in FIG. 3).

On the other hand, if the expiration date is set, the available call time limiter 20 sets ON in the memory C23 (step S13 in FIG. 3) and requests the administrator to input the expiration date (step S3 in FIG. 3). S14). Talk time limiter 2
0 indicates that when an expiration date is input from the administrator,
The expiration date is written in (step S15 in FIG. 3).

In the case of the integrated outgoing call time monitoring process by the portable telephone terminal 1, when a calling operation from the user is performed (step S21 in FIG. 4), the value of the memory A21 is changed to the value of the memory B22. It is determined whether it is greater than (step S22 in FIG. 4).

If the value in the memory A21 is smaller than the value in the memory B22, the available call time limiter 20 notifies the user that the call cannot be made (step S23 in FIG. 4), and executes the integrated outgoing call time monitoring process. finish.

On the other hand, if the value of the memory A21 is larger than the value of the memory B22,
Since the transmission to the other party is permitted, the control unit 11 makes a call to the other party (step S24 in FIG. 4), and when the other party performs an incoming call operation, the communication state is set (step S25 in FIG. 4).

The control unit 11 monitors whether there is a disconnection request from the user or the other party (step S2 in FIG. 4).
6) If there is a disconnection request, the call is disconnected (step S30 in FIG. 4), and the available call time limiter 20 ends the integrated outgoing call time monitoring process.

If there is no disconnection request, the control unit 11 keeps the communication state as it is. When the unit time has expired (step S27 in FIG. 4), the communication time limit unit 20 sets the memory B22.
And the unit time (1 second) (step S28 in FIG. 4),
It is determined whether the value of the memory A21 is equal to the value of the memory B22 (step S29 in FIG. 4).

If the value of the memory A21 is not equal to the value of the memory B22, the available time limit unit 20 notifies the control unit 11 of the fact, and the control unit 11 keeps the communication state. The callable time limit unit 20 is provided in the memory A2.
If the value of 1 is equal to the value of the memory B22, the fact is notified to the control unit 11, and the control unit 11 disconnects the call (step S30 in FIG. 4).
Ends the integrated outgoing call time monitoring process.

Subsequently, in the case of the expiration date check processing automatically performed by the portable telephone terminal 1 every day, the communicable time limit unit 20 determines that the memory C23 is not ON (FIG. 5).
Step S41), the control unit 11 is notified of this, and the expiration date checking process ends.

If the memory C23 is ON (step S41 in FIG. 5), the communicable time limiter 20 sets the memory D
The unit time (1 day) is subtracted from 24 (step S4 in FIG. 5).
2) It is determined whether the value of the memory D24 has become "0" (step S43 in FIG. 5).

If the value of the memory D24 is not "0", the available call time limit unit 20 notifies the control unit 11 of the fact and ends the expiration date check processing. If the value in the memory D24 is "0", the available call time limiter 20 writes "0" in the memory B22 (step S44 in FIG. 5), notifies the controller 11 of the fact, and notifies the controller 11 of the expiration date. The check processing ends.

In this case, in the portable telephone terminal 1, when the outgoing call available time in the memory A21 and the integrated outgoing call time in the memory B22 become the same value, unless the administrator resets the outgoing call available time, the user is not allowed to do so. Cannot make outgoing calls.

In the expiration date checking process performed by the available call time limiter 20 performed every day, the expiration date set by the administrator is decremented every day.
Reset the total outgoing call time.

In this embodiment, the portable telephone terminal 1 has been described, but a PHS (Personal Handyph) is used.
One system) can be applied to all information terminals. Further, although the outgoing call has been described in the present embodiment, it is apparent that the present invention can be applied to an incoming call. Furthermore, when the outgoing call available time expires during the outgoing call, the call is forcibly terminated, but the call can be kept as it is, and the next outgoing call can be disabled.

Further, the memory A21 and the memory B2
2 Each unit is "second", but "minute" or "hour"
And the like, and the unit of the memory D24 is “days”. However, it is also possible to apply to “week”, “month”, and the like.

As described above, the available call time limiter 20 performs the outgoing call available time and expiration date setting process, the integrated outgoing call time monitoring process, and the expiration date check process to manage the outgoing call by the user. Valid only within the scope of the person's permission. Also, as described above, the outgoing call available time can be freely set by the administrator, and after the outgoing call available time has expired, the outgoing call available time can be set only by the administrator without going through the mobile phone carrier. It is possible to automatically make outgoing calls after the expiration date, even if the accumulated outgoing call time exceeds the outgoing call available time before the expiration date and the outgoing call is not possible. Can be.

[0035]

As described above, according to the present invention, when a password input from the outside is determined to be correct, a call is made with the first storage means for storing the talkable time set from the outside. By performing writing to the second storage means for storing the accumulated call time and disabling the call when the contents stored in the first storage means and the contents stored in the second storage means match, the flexible call The available time can be set, and even after the available time has expired, the available time can be set without going through the mobile phone carrier.
