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 in addition to making calls, it is possible to access the network to obtain various information and purchase products. It is possible.

  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.

  Mobile phones that can receive TV programs have also appeared, but by leaving mobile phones with such functions to children, it becomes possible to watch TV programs regardless of time or place. For this reason, it is preferable to restrict the use of television programs from the viewpoint of education.

  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.

  That is, in the above technique, there are only two states of whether or not to stop the use of the communication terminal, so there is no room for the parent to consider the restriction range of use of the communication terminal. I could only do it.

  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 present invention provides a clock unit that provides time information, first information that indicates whether or not television viewing restriction is valid, and a second time zone that restricts television viewing. When the first information is set to be valid and the time information indicated by the clock part is within the time zone indicated by the second information, And a prohibiting means for prohibiting viewing of television.

  According to the present invention, since the administrator can finely limit the range of use of the communication terminal, it is possible to prevent a managed person such as a child from using beyond the range intended by the administrator.

  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. In addition, 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 configuration is provided in a conventional cellular phone. In addition to the above configuration, the cellular phone 1 according to the present invention includes an authentication unit 11-1, a restriction information registration processing unit 11-2, An operation processing unit 11-3 is provided, 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 restriction information registration processing unit 11-2 performs the restriction information setting process for the restriction information storage area 12-2, and the permission list storage area 12-3 has the restriction mode even when the restriction mode is set to ON. This stores information that is not subject to restriction.

  In the password storage area 12-1, a 4-digit password such as “0000” may already be registered when the mobile phone 1 is purchased, but such a pre-registered password is relatively easy. In order to limit the operation of the mobile phone 1 more thoroughly, it is necessary to store information such as one week in the storage unit 12 in advance after the use of the restriction mode is started. A message prompting the user to change the password may be displayed on the display unit 17 at the timing when the password for enabling or disabling the restriction mode is input after the elapse of the operation).

  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 use. It is composed of six areas: volume limit 12-2 (d), TV usage time zone 12-2 (e), and radio usage time zone 12-2 (f). Information indicating whether or not the cellular phone 1 is set to the restriction mode is access restriction 12-2 (b), the restriction information about the telephone function, mail function, web access function, and application program download function is the time. The restriction 12-2 (c) includes information indicating a usable time zone per day and information indicating whether or not the use time is restricted for each of the three functions. For each of the above three functions The usage limit is registered for the TV usage time zone 12-2 (e), the effective time zone for the TV reception function, and for the radio usage time zone 12-2 (f), the effective time zone for the radio reception function is registered. ing.

  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). The address book 12-3 (a) is registered with a telephone number, a partner name, a photograph showing the partner, and the like used for making and receiving calls. 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. It consists of two areas, 12-3 (a) and favorites 12-3 (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

  The signal processing unit 16 passes the control signal to the control unit 11 when the control signal is extracted from the signal received from the transmission / reception unit 15, and conversely when the control signal is received from the control unit 11 The signal is converted into a baseband signal and similarly passed to the transmission / reception unit 15.

  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 in a parent or manager to limit the operation of the mobile phone 1 will be described.

  When the administrator activates the power supply of the cellular phone 1, calls the menu screen using the operation unit 18, and selects the setting menu for the restricted mode from the menu screen, the display unit 17 displays a screen requesting input of a password. Is done.

  Here, when the administrator uses the operation unit 18 to input a password made up of, for example, four-digit characters and numbers and makes an authentication request, the authentication unit 11-1 enters the password registration area 12-1. It is judged whether it matches the registered password. If it matches, the setting of the restricted 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 the limit mode, the access limit, the time limit, the usage limit, and the TV usage time. Since six selection item names of band restriction and radio usage time band restriction are displayed, the administrator selects an item desired to be set from these 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, the access restriction 12-2 (b), the time restriction 12-2 (c), the usage amount restriction 12-2 (d), and the TV use time zone restriction 12-2 (E) And the operation | movement of the mobile telephone 1 is restrict | limited according to the state set to each item of the radio use time zone restriction | limiting 12-2 (f).

  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 items displayed on the display unit 17 at this time are 11 items in the access restriction 12-2 (b) in FIG. 2, and the display unit 17 does not have a display area sufficient to display 10 items. The item names may be displayed sequentially by scrolling using the cross key of the operation unit 18 or the like.

  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 or not to restrict call processing, “Mail function” to set whether or not to restrict sending mail to unauthorized parties, Restrict 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 web connection by directly entering an address, “Content subscription” to set whether to restrict password entry on web content In addition, there are items of “application D / L” for setting whether to restrict downloading of the application program.

  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 of all items may be prepared.

  As described above, when the setting for each item of access restriction is completed, an input restriction state is confirmed by performing a confirmation operation on the access restriction item selection screen, and this state is determined as the access restriction storage area 12-2. Registered in

  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.

  The application program is mainly intended for a program such as a game. By restricting the download of such a program, a child having the mobile phone 1 can use it as a play tool. It becomes possible to prevent.

  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 to restrict the use, for example, to restrict the use at midnight, the restriction start time is 21:00 and the restriction end time is 07:00. input.

  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.

  Although it has been described that the restricted time zone is registered as the restricted time zone, it can be implemented so that it is not restricted, that is, a time zone in which a call is permitted. is there.

  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.

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

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

  In this usage restriction, “call time” for setting the time limit for outgoing call time for one month, “mail transmission / reception” for setting the limit for the number of received mails, and the number of subsequent emails to be sent, And it is comprised from three items of "web connection" for setting the restriction | limiting amount of the amount of transmission / reception information received by web connection in one month.

  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. Also, as a matter of course, the call time, the number of mail transmission / reception, and the amount of data received by accessing the site are reset to zero every time a preset period such as one month elapses.

  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, by operating the operation unit 18, for example, if the total call time is limited to 60 minutes, “60” is input and a confirmation operation is performed to confirm the input 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 30. If the user wants to limit the number to “30”, he / she enters “30” to perform a confirmation operation.

  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, the display unit 17 displays a screen for setting the upper limit of the total amount of data received by connecting to the web. For example, if it is desired to limit the amount of received data to 80 kbytes, “80” may be input 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 limit, and this state is the usage limit 12- 12 in the usage limit storage area 12-2. 2 (d).

  When the TV usage time limit is selected, a screen for limiting the TV viewing is first displayed on the display unit 17. Here, an item for setting whether to apply a restriction and an item for inputting a restricted time zone are displayed.

When the administrator places a restriction on viewing of the television, the operation unit 18 is operated to select an item for enabling or disabling the restriction, and the display content is set to ON. If the time zone to be restricted is not set, the operation unit 18 is similarly operated to select an item for inputting the time zone, and the time zone to be restricted is input. This input is the same as the time limit input, and the start time and end time of the limit are input. For example, if it is desired to limit the viewing of the television to 3 hours from 12:00 to 15:00, it is only necessary to input 15:00 as the start time and 12:00 as the end time.

  When the radio usage time zone restriction is selected, an item for setting whether or not to restrict the display unit 17 and an item for inputting the restricted time zone are displayed as in the case of the television. For this reason, when it is desired to apply a restriction, an item for setting valid or invalid is selected and the display content is set to ON. When setting the time zone, an item for inputting the time zone is selected, and the start time and end time, for example, 06:00 as the start time and 08:00 as the end time are input.

  By setting each item as described above, an administrator such as a parent or a manager can place certain restrictions on the use of the child or his subordinate who keeps the mobile phone 1.

  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. As with the restriction information storage area 12-2, the setting can be made by selecting “permission list” from the items displayed on the display unit 17 after clearing the authentication by the password. The permission list is made up of a telephone book 12-3 (a), an address book 12-3 (b), and a favorite 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 requires 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.
