JP3712718B2 - Communication terminal - Google Patents

Description

The present invention relates to a communication terminal capable of making and receiving calls using a telephone directory in which a telephone number and the name of a partner are registered, and accessing various information sources provided via a network.

Communication terminals such as PHS (Personal Handy-phone System) and mobile phones are becoming more and more functional, and not only making calls but also accessing the network to acquire various information,
It is possible to purchase products.

However, as mobile terminals have spread to a wide range of age groups, for example, cases of being used as a means of communication between parents and children are increasing, but a child who is given a mobile terminal due to the above-mentioned multi-functionality is not intended by parents. There is a growing need to limit the use of managed communication terminals, such as accessing information sources and responding to incoming calls from inappropriate parties.

Even now, various methods for restricting the use of communication terminals are being studied. As a simple technique, a function for locking the key input of the communication terminal is provided, and a user registers a password. There is a way to release this lock.

In addition, when a key input of a mobile phone is dropped in an unlocked state, the function of the mobile phone is stopped by an impact caused by the drop, and unauthorized use when lost is made (Patent Document) 1).
JP 2001-177639 A

However, the method for restricting the use of the communication terminal as described above does not consider the use restriction between the parent and child, that is, between the administrator and the managed person. The use could not be restricted.

In other words, in the above technique, there are only two states of whether to stop using the communication terminal,
There was no room for parents to consider the range of restrictions on the use of communication terminals. Eventually, the use was limited only by instructions to children.

Such restrictions on communication terminals are the same not only in parent-child relationships but also in relationships between managers and their subordinates when a communication terminal is introduced in a company.

In order to achieve the above object, the first invention restricts at least one of the functions of telephone transmission, mail transmission, and site access of a communication terminal so that it cannot be used during a predetermined time period. A storage unit for storing the function restriction information, a clock unit for providing time information, the at least one function is controlled based on the function restriction information and the time information, and the function restriction information stored in the storage unit is stored in the storage unit. And a control unit that performs control so as not to accept the setting change of the clock unit when it is set to be valid .
In addition, in the second aspect of the present invention, in the communication terminal provided with the input unit, the predetermined time zone for the authentication information and at least one of the function of calling the telephone, sending the mail, and accessing the site of the communication terminal is A storage unit that stores function restriction information for restricting use so that it cannot be used, a clock unit that provides clock information, and the at least one function is controlled based on the function restriction information and the clock information. When the stored function restriction information is set to be valid, control is performed so as not to accept the setting change of the clock unit, and the authentication information input by the input unit and the authentication information of the storage unit match And a control unit that allows the function restriction information to be changed and the function restriction to be enabled / disabled .

According to the present invention, an administrator, that is, a person who lends a communication terminal can limit the use time of the communication terminal by the user to an optimal time zone. Can be suppressed to a common sense range.
In addition, when the use of the communication terminal is restricted to a set time zone or the like, since the time setting is not accepted, it is possible to prevent the set restriction from being invalidated.

  Embodiments of the present invention will be described below with reference to the drawings.

Hereinafter, Embodiment 1 of the present invention will be described with reference to FIG. Note that a mobile phone is given as a specific example of the communication terminal of the present invention, and description will be made based on the configuration of the mobile phone.

FIG. 1 is a diagram illustrating a schematic configuration of a mobile phone 1. The mobile phone 1 includes a control unit 11, a storage unit 12, a clock unit 13, an antenna 14, a transmission / reception unit 15, a signal processing unit 16, and various key input units. Are provided with a display unit 18 for displaying characters and image information, a speaker 19 for outputting a received voice or a melody, and a microphone 20 for inputting a voice signal.

The above-described configuration is provided in a conventional mobile phone. In the mobile phone 1 according to the present invention, in addition to the above configuration, the control unit 11 includes an authentication unit 11-1 and a restriction information registration processing unit 11-2.
And an operation processing unit 11-3, and the storage unit 12 includes a password storage area 12-
1, a restriction information storage area 12-2, and a permission list storage area 12-3.

In the above configuration, the control unit 11 controls the operation of the mobile phone 1, and transmits and receives signals to and from a base station (not shown), processes signals input via the operation unit 18, and the display unit 17. Controls the display of characters and images on

Then, whether the authentication unit 11-1 of the control unit 11 matches the password registered in the password storage area 12-1 in order to set the restriction mode described in detail below. The limit information registration processing unit 11-2 determines the limit information storage area 1
Restriction information setting processing for 2-2 is performed, and the permission list storage area 12-3 stores information that is not subject to restriction even when the restriction mode is set to ON.

The storage unit 12 stores programs and setting information necessary for the operation of the mobile phone 1, and detailed configurations of the restriction information storage area 12-2 and the permission list 12-3 are shown in FIGS. 2 and 3, respectively. Is shown in

First, as shown in FIG. 2, the restriction information storage area 12-2 is roughly divided into a restriction mode 12-2 (a), an access restriction 12-2 (b), a time restriction 12-2 (c), and The usage limit 12-2 (d) is composed of four areas. The restriction mode 12-2 (a) is information indicating whether or not the mobile phone 1 is set to the restriction mode. 2
(B) shows restriction information about telephone function, mail function, web access function, time restriction 1
2-2 (c) is information indicating a usable time zone per day, information indicating whether or not the usage time is limited for each of the three functions, and the usage limit 12-2 (d) is Usage limits for each of the three functions are registered.

As shown in FIG. 3, the permission list 12-3 includes three areas: a telephone book 12-3 (a), an address book 12-3 (b), and a favorite 12-3 (c). In the address book 12-3 (a), a telephone number used for making and receiving calls, a partner name, a photograph showing the partner, and the like are registered. The address book 12-3 (b) is an area for registering a mail address, but the mail address can also be handled as a registered item in the telephone book. In this case, the permission list 12-3 is a telephone book. 12-3 (a) and Favorites 12-3
It is composed of two areas (c).

The favorite 12-3 (c) is an area for registering position information (URL) of an information source accessed via the Internet.

The clock unit 13 is for supplying time information to the mobile phone 1, and can be set and corrected by the user via the operation unit 18.

The antenna 14 transmits / receives a radio signal to / from a base station (not shown). The radio signal received by the antenna 14 is converted into a baseband signal by the transmitting / receiving unit 15 and supplied to the signal processing unit 16. . When the signal processing unit 16 extracts an audio signal from the baseband signal, the signal processing unit 16 converts the extracted signal into an analog signal and supplies the analog signal to the speaker 19.

On the other hand, the audio signal input from the microphone 20 is converted to a baseband signal by the signal processing unit 16 and then sent to the transmission / reception unit 15 where it is converted to a radio signal and transmitted from the antenna 14 to the base station. The

In addition, when the signal processing unit 16 extracts the control signal from the signal received from the transmission / reception unit 15, the signal processing unit 16 passes the control signal to the control unit 11, and conversely, when the control signal is received from the control unit 11,
This control signal is converted into a baseband signal and passed to the transmission / reception unit 15 in the same manner.

  The operation of the mobile phone according to the first embodiment having the above configuration will be described below.

First, setting input for a manager who is a parent or manager to restrict the operation of the mobile phone 1 will be described.

The administrator activates the power supply of the mobile phone 1, calls the menu screen using the operation unit 18,
When a restriction mode setting menu is selected from this menu screen, a screen requesting input of a password is displayed on the display unit 17.

Here, when the administrator uses the operation unit 18 to input a password composed of, for example, four-digit characters and numbers, and issues an authentication request, the authentication unit 11-1 displays the password registration area 12-
Whether the password matches the password registered in 1 is determined. If they match, the setting of the restriction mode is permitted.

If the password authentication does not match, the user is prompted to enter the password again. Here, if the password authentication process fails a predetermined number of times, for example, three times, access to the restricted mode is rejected. In this case, the password input may not be accepted for a predetermined time, and the password authentication process It is also possible to deny access to the restricted mode if it fails even once.

When the password authentications match, the display unit 17 sets “restriction setting” for setting information for restricting the use of the mobile phone 1 and the contents of the permission list described in detail below. “Allow list” is displayed as an item. Here, it is assumed that the administrator selects “limit setting” in order to set the limit information. At this time, the display unit 17 displays four selections of a limit mode, an access limit, a time limit, and a usage limit. Since the item name is displayed, the administrator selects an item to be set from the selection items.

If the access restriction item is selected here, the display unit 17 is a menu for setting one of two states, whether the restriction mode is enabled or disabled in this access restriction. The state set in the restriction mode storage area 12-2 (a) at the time of operation, for example, ON is displayed.

The administrator operates the operation unit 18 to cancel the access restriction selection when keeping the restriction mode valid, and operates the operation unit 18 to display the display unit 17 when invalidating the restriction mode. Is switched from ON to OFF and a confirmation operation is performed.

By this processing, the restriction mode can be switched ON / OFF, and this information is set in the restriction mode storage area 12-2 (a).

When the restriction mode is set to ON, access restrictions 12-2 (b), 12
-The operation of the mobile phone 1 is restricted according to the state set to 2 (c) and 12-2 (d).

Subsequently, when an access restriction item is selected by the administrator after matching in the password authentication processing, the lower layer item names that can be set by the access restriction are displayed on the display unit 17.

The item displayed on the display unit 17 at this time is 1 in the access restriction 12-2 (b) in FIG.
If there are 0 items and the display unit 17 does not have a display area sufficient to display 10 items,
What is necessary is just to display an item name sequentially by scroll operation of the operation part 18. FIG.

In addition, as shown in 12-2 (b), the access restriction includes “call transmission” for setting whether or not to restrict call processing to an unauthorized party, and incoming calls from an unauthorized party. "Call incoming" to set whether to restrict call processing, "Email function" to set whether to restrict sending mail to unauthorized parties, access to unauthorized sites “Web function” for setting whether or not, setting whether or not to limit outgoing calls to a call history within a predetermined time (for example, 3 seconds) from a partner not registered in the phone book 12-3 (a) "One-cut call", "Q2 call" to set whether or not to restrict dialing Q2, "International call" to set whether or not to restrict international calls, link included in received mail Set whether to restrict access to information "Link string", "Address input" to set whether to restrict the web connection by directly entering the address, and to set whether to restrict password entry on the web content "Content subscription" There are each item.

When the administrator operates the operation unit 18 to select an item to be set, the state (ON or OFF) set for each item at that time is displayed on the display unit 17. The operation unit 18 is used for setting in the state to be set, and the setting content is confirmed by a confirmation operation.

In addition to setting valid / invalid for each item, a menu that enables valid / invalid setting for all items may be prepared.

As described above, when the setting for each item of access restriction is completed, the state of the input access restriction is confirmed by performing a confirmation operation on the access restriction item selection screen,
This state is registered in the access restriction storage area 12-2 (a).

It should be noted that the Q2 call and the international call call are determined based on whether or not a code preset by the administrator, for example, “0990” or “0041” is included in the call phone number.

On the other hand, when the time limit is selected, the lower layer item names that can be set by the time limit are displayed on the display unit 17, so the administrator selects the desired item by operating the operation unit 18. Do.

In this time restriction, a “restricted time period” for setting a time period for restricting the use of the mobile phone 1 within one day, and a “telephone” setting whether or not to restrict calls outside the restricted time period "Outgoing", "Call incoming" to set whether to restrict incoming calls outside the time limit, "Mail transmission" to set whether to restrict mail transmission outside the time limit, and time limit It consists of four items of “Web connection” for setting whether or not to limit the web connection outside the band.

The administrator selects an item to be set and inputs the setting in the same manner as described above. However, when the time limit is selected, an input screen for designating the time zone is displayed on the display unit 17. ,
When the administrator operates the operation unit 18 and wants to restrict the use, for example, late-night use, enter 22:00 as the restriction start time and 7:00 as the restriction end time. To do.

When the confirmation operation is performed by inputting the start and end time zones in this way, a time zone for restricting use is set.

On the other hand, for each item of outgoing call, incoming call, mail transmission, and web connection, as with access restriction, either valid or invalid, that is, ON or OFF is set.

Also, by performing a confirmation operation on the item selection screen for time limit, each state set by the time limit is confirmed, and the state set in the time limit storage area 12-2 (c) is registered.

Finally, when the usage amount restriction is selected by the administrator, the display unit 17 displays the lower layer item names that can be set by the usage amount restriction. The item to be selected is selected.

In this usage limit, “call time” for setting the time limit for outgoing call time for one month
“Mail Send / Receive” to set the limit on the number of emails sent and received for one month, and “Web Connection” to set the limit on the amount of sent / received information received by connecting to the web in one month Are comprised of three items.

In this example, the unit is one month, but it goes without saying that any unit such as a day unit or year unit can be used.

In this case, the administrator selects an item to be set and inputs the setting in the same manner. However, when the call time is selected, the display unit 17 displays a screen for setting the total call time in minutes. Therefore, if the operation unit 18 is operated to limit the total call time to 20 minutes, for example, “20”.
To confirm the entered value.

When an item for mail transmission / reception is selected, a screen for inputting the number of mails for restricting mail transmission / reception is displayed on the display unit 17. For example, the total number of mail transmissions and subsequent mail receptions is 40. If it is desired to limit the number to 40, the confirmation operation is performed by inputting "40".

The continued mail is intended to receive the remaining part when receiving a part of the mail free of charge and paying for receiving the remaining part.

When the web connection item is selected, a screen for setting an upper limit value of the total amount of data received by connecting to the web is displayed on the display unit 17.
For example, when the operation unit 18 is operated to limit the amount of received data to 40 kbytes, “40
”And the confirmation operation may be performed in the same manner.

After performing such setting processing, the status of each setting item is confirmed by performing a confirmation operation on the item selection screen for usage amount restriction, and this state is registered in the usage amount restriction storage area 12-2 (d). The

By setting each item as described above, an administrator such as a parent or a manager can make the cellular phone 1
It is possible to place certain restrictions on the use of children and subordinates.

On the other hand, the permission list 12-3 is an area for setting information that can be used without being restricted even when a certain restriction is imposed on the use of the mobile phone 1, as described above.
Similarly to the restriction information storage area 12-2, the setting of -3 can be set by selecting “permission list” from the items displayed on the display unit 17 after clearing the authentication by the password. The permission list includes the phone book 12-3 (a), the address book 12-3 (b),
And it consists of favorites 12-3 (c).

Even when, for example, a telephone number such as home, school, or parent's office is registered in the telephone book 12-3 (a), the restriction mode is set to be effective, and outgoing and incoming calls are restricted. This makes it possible to make and receive calls and to prevent contact from being lost in an emergency.

In the address book 12-3 (b), as in the telephone book 12-3 (a), an e-mail address used for emergency contact is registered.

On the other hand, since the favorite 12-3 (c) is useful information, access information to a site that does not need to be restricted is registered. For example, there are access to a site that needs information collection for business, information for accessing a site that provides information necessary for learning, and the like.

In each of the above settings as well, the information input via the operation unit 18 is registered by performing the confirmation operation in the same manner as the restriction setting.

The mobile phone 1 has an all reset function for clearing all the set states and a function for correcting the setting of the clock unit 13, but the restriction mode is set to be valid. When the restriction mode storage area 12-2 (a) is ON, the all clear reset and the setting change function of the clock unit 13 are controlled not to operate.

In this way, the restriction mode information set by the administrator is prevented from being invalidated by the operation of the managed person.

Some mobile phones 1 have a function for enabling / disabling the function of automatically transmitting the location information acquired by the mobile phone 1 in response to a request from the other mobile phone. Control is made so that the location information is returned in the case of a request from the other party registered in the permission list 12-3 even when the owner of the mobile phone 1, in this case, is set to invalid by the operation of the manager. Let

In this way, the administrator can acquire the position information without being affected by the setting of the mobile phone 1, and therefore, for example, when the managed person cannot respond to the calling process or the incoming call. However, it is possible to confirm the location.

Moreover, about the call to a police station or a fire department, you may make it not prevent an emergency call by setting so that it may not be restrict | limited by restriction | limiting mode.

In addition, in the case where the state set by the user who is a managed person and the state in which the operation of the mobile phone 1 is restricted in the restriction mode indicate a conflict, by enabling the restriction mode setting, It is possible to prevent the information set by the administrator from being invalidated unexpectedly.
