Description

  The present invention relates to a mobile phone device having a call function, an electronic mail transmission / reception function, an Internet connection function, and the like, and a use management method of the mobile phone device.

  2. Description of the Related Art Conventionally, in addition to an original call function, a mobile phone device having an electronic mail transmission / reception function capable of transmitting / receiving electronic mail and an internet connection function capable of connecting to the Internet is known. In addition, the age of use of such a multifunctional mobile phone device tends to decrease year by year, and it is not uncommon for elementary school students to have their own mobile phone devices.

  By the way, such a multi-function mobile phone device is convenient, but has a risk of being lost or stolen due to the nature of being carried outdoors. When a mobile phone device is used by a theft, the usage fee is charged by a business operator, or personal information stored in the memory of the mobile phone device is known. For this reason, in the said mobile telephone apparatus, use of each function can be restrict | limited by performing predetermined operation (junior mode (trademark)).

  Specifically, when a parent causes a child to use a mobile phone device, it does not mean that all functions are locked, and it is necessary to release the lock so that the minimum functions necessary for the child can be used. There is. The junior mode (registered trademark) is a state in which the lock is released so that the minimum function necessary for the child can be used, and the child uses the function of the mobile phone device by the junior mode (registered trademark). be able to.

  Note that the above prior art is a public technique, and the present invention has been developed based on the public technique. For this reason, the applicant does not know the existence of a document known invention related to the present invention at the time of filing a patent application, and omits the description of the name of the document known invention and the location of information relating to other known documents.

  However, usage restrictions such as the number of times of e-mail transmission, telephone call time, and internet connection time in the junior mode (registered trademark) are preset in advance, and the usage status is managed monthly. For example, if the number of email transmissions, phone call time, and internet connection time for a month are less than the default values, the lesser amount is set for the next month from the standpoint of fairness and maintaining a constant usage fee. It is necessary to increase only the initial setting value.

  Therefore, in consideration of the above circumstances, the present invention provides a mobile phone device and a mobile phone device that can freely and easily change use restrictions of each function of the mobile phone device regardless of a preset initial setting value. The purpose is to provide a usage management method.

The invention described in claim 1 is a storage means for storing the contents of the use restriction of the predetermined function, and a first lock means for restricting the use of the predetermined function based on the use restriction contents stored in the storage means. And second lock means for changing the content to a usage restriction different from the content of the usage restriction stored in the storage means in a state where the use of a predetermined function is restricted by the first locking means. It is characterized by that.

  According to a second aspect of the present invention, in the mobile phone device according to the first aspect of the present invention, since the second lock unit changes the usage limit to a content different from the usage limit stored in the storage unit. It has automatic control means for releasing the locked state by the second locking means and returning to the locked state by the first locking means after a predetermined period.

  According to a third aspect of the present invention, in the cellular phone device according to the first aspect, the content of the use restriction stored in the storage means is a usage amount, and the usage amount and the usage amount actually used by the user. And a correction means for correcting the content by adding the difference to the content of the use restriction stored in the storage means, and the correction is performed by the second lock means. The content is changed to use restriction.

  According to a fourth aspect of the present invention, there is provided a first locking step in which use of a predetermined function is restricted by the first locking means based on the content of the use restriction stored in the storage means, and a predetermined locking by the first locking means. A second lock step in which the content of the use restriction stored in the storage means is changed to a use restriction of another content by the second lock means in a state in which the use of the function is restricted. .

  According to a fifth aspect of the present invention, in the method for managing the use of the mobile phone device according to the fourth aspect, the automatic control means uses the second lock means after a lapse of a predetermined period from the end of the second lock process. An automatic control step is provided in which the locked state is released and the locked state is restored by the first locking means.

  According to a sixth aspect of the present invention, in the usage management method for a mobile phone device according to the fourth aspect, the content of the usage restriction stored in the storage means is a usage amount, which is actually used by the usage amount and the user. A calculation step in which the difference from the used amount is calculated by the calculation unit, and a correction step in which the difference is added to the content of the use restriction stored in the storage unit and the content is corrected by the correction unit. In the second locking step, the second locking unit changes the usage limit to the corrected content.

  According to the first aspect of the present invention, the use of the predetermined function is restricted by the first lock means based on the contents of the use restriction stored in the storage means. As a result, a so-called junior mode (registered trademark) is set, and a predetermined function cannot be used unless the first locking means is released.

  Here, in a state where the use of a predetermined function is restricted by the first locking means, the content can be changed to a usage restriction different from the contents of the use restriction stored in the storage means by the second locking means. For this reason, it is possible to restrict the use of a predetermined function based on the content of the use restriction stored in the storage means by operating the first lock means, but the use stored in the storage means for the convenience of the user or the like When it is desired to change the contents of the restriction, the use restriction of another content can be changed by the second lock means. As described above, regardless of the preset initial setting values, it is possible to freely and easily change the use restriction of each function of the mobile phone device, and the convenience can be greatly improved.

  According to the second aspect of the present invention, the automatic control means performs the first operation after a predetermined period has elapsed since the content of the use restriction stored in the storage means by the second lock means is changed to a use restriction different from the content. The locked state by the two locking means is released, and the locked state by the first locking means is restored. Thereby, it is possible to automatically return to the contents of the use restriction stored in the storage means, and it is possible to realize the use restriction by the first lock means.

  According to the third aspect of the present invention, the difference between the content of the use restriction stored in the storage unit and the usage amount actually used by the user is calculated by the calculation unit. For example, a value (difference) obtained by subtracting the call time when the user actually talked from the call time stored in the storage unit, or the number of times the user actually transmitted the email from the number of email transmissions stored in the storage unit Or a value (difference) obtained by subtracting the Internet connection time when the user actually connected to the Internet from the Internet connection time stored in the storage means.

  In addition, the difference is added to the content of the use restriction stored in the storage unit by the correcting unit. For example, the value obtained by subtracting the call time when the user actually made a call from the call time stored in the storage means, or the number of times the user actually sent the e-mail was subtracted from the number of e-mail transmission times stored in the storage means. The value obtained by subtracting the Internet connection time when the user actually connected to the Internet from the Internet connection time stored in the storage means is the call time stored in the storage means, the number of times of e-mail transmission, or the Internet It is added to each connection time. As a result, if the difference becomes positive, the call time, the number of times of e-mail transmission, and the Internet connection time stored in the storage means become longer than those at the beginning. And it is changed to the use restriction of the corrected content by the second locking means.

  As described above, even when the use of a predetermined function of the mobile phone device for a certain period is temporarily reduced compared to the content of the use restriction stored in the storage means, the difference is automatically calculated and By adding to the content of the use restriction stored in the storage means, the usage amount of the predetermined function of the user can be kept constant.

  According to the fourth aspect of the present invention, in the first locking step, the use of the predetermined function is restricted by the first locking means based on the contents of the use restriction stored in the storage means. Thereby, a predetermined function cannot be used unless the first locking means is released.

  Next, in the second locking step, the content of the usage restriction stored in the storage means by the second locking means is changed to a usage restriction of another content while the use of the predetermined function is restricted by the first locking means. Is done. For this reason, it is possible to restrict the use of a predetermined function based on the content of the use restriction stored in the storage means by operating the first lock means, but the use stored in the storage means for the convenience of the user or the like When it is desired to change the contents of the restriction, the use restriction of another content can be changed by the second lock means. As described above, regardless of the preset initial setting values, it is possible to freely and easily change the use restriction of each function of the mobile phone device, and the convenience can be greatly improved.

  According to the fifth aspect of the present invention, after the second locking step, after the predetermined period has elapsed, in the automatic control step, the locked state of the second locking unit is released by the automatic control unit, and the first locking unit. Return to the locked state by. Thereby, it is possible to return to the contents of the use restriction stored in the storage means, and it is possible to realize the use restriction by the first lock means.

  According to the sixth aspect of the present invention, in the calculation step, a difference between the content of the use restriction stored in the storage unit by the calculation unit and the usage amount actually used by the user is calculated. For example, a value (difference) obtained by subtracting the call time when the user actually talked from the call time stored in the storage unit, or the number of times the user actually transmitted the email from the number of email transmissions stored in the storage unit Or a value (difference) obtained by subtracting the Internet connection time when the user actually connected to the Internet from the Internet connection time stored in the storage means.

  Further, in the correction step, the difference is added to the content of the use restriction stored in the storage unit by the correction unit. For example, the value obtained by subtracting the call time when the user actually made a call from the call time stored in the storage means, or the number of times the user actually sent the e-mail was subtracted from the number of e-mail transmission times stored in the storage means. The value obtained by subtracting the Internet connection time when the user actually connected to the Internet from the Internet connection time stored in the storage means is the call time stored in the storage means, the number of times of e-mail transmission, or the Internet It is added to each connection time. As a result, if the difference becomes positive, the call time, the number of times of e-mail transmission, and the Internet connection time stored in the storage unit become longer than those at the beginning. Then, in the second locking step, the second locking unit changes the usage limit to the corrected content.

  As described above, even when the use of a predetermined function of the mobile phone device for a certain period is temporarily reduced compared to the content of the use restriction stored in the storage means, the difference is automatically calculated and By adding to the content of the use restriction stored in the storage means, the usage amount of the predetermined function of the user can be kept constant.

  The communication unit 12 is connected to the baseband unit 14. The baseband unit 14 includes a CDMA processing circuit 18 and an audio codec 20. Here, the CDMA processing circuit 18 performs code division multiple access, scrambling, error control, and timing detection. The audio codec 20 compresses (encodes) and decompresses (decodes) the audio, performs analog and digital conversion, and changes the received sound volume and microphone sensitivity by an internal amplifier circuit (not shown). .

  In addition, a switching circuit 22 is connected to the baseband unit 14. A first speaker 26 is connected to the switching circuit 22 via an amplifier circuit 24. The first speaker 26 converts the electric signal of the baseband unit 14 amplified by the amplifier circuit 24 into sound. This first speaker 26 is applied to the user's ear and used for a call.

  Further, the microphone 30 is connected to the switching circuit 22 via the amplifier circuit 28. The microphone 30 is used for a call and converts sound into an electrical signal. The electrical signal output from the microphone 30 is amplified by the amplifier circuit 28 and output to the baseband unit 14.

  Further, a second speaker 34 is connected to the switching circuit 22 via an amplifier circuit 32. The second speaker 34 converts the electric signal of the baseband unit 14 amplified by the amplifier circuit 32 into sound. The second speaker 34 is a loudspeaker for listening to the surrounding people of the received sound. The second speaker 34 also sounds an incoming call notification. Note that the gains of these three amplifier circuits 24, 28, and 32 are fixed, and the volume of the first speaker 26 and the second speaker 34 and the sensitivity of the microphone 30 cannot be changed.

  The switching circuit 22 is connected to the baseband unit 14 on the side of the amplifier circuit 24 for the first speaker 26 and the amplifier circuit 28 for the microphone 30, or the amplifier circuit 32 for the second speaker 34 for loud sound. And switching to the amplifying circuit 28 side for the microphone 30.

  A control circuit 36 is connected to each of the communication unit 12, the baseband unit 14, and the switching circuit 22. Switching by the switching circuit 22 described above is performed under the control of the control circuit 36. The control circuit 36 controls the audio codec 20 of the baseband unit 14, and the audio codec 20 changes the volume of the first speaker 26 and the second speaker 34 and the sensitivity of the microphone 30. The control circuit 36 is connected to the ROM 38 and controls each unit based on a system program stored in the ROM 38. The control circuit 36 is connected to a RAM 40 in which predetermined information necessary for the operation of the control circuit 36 is stored.

  Here, the configuration of the control circuit (control means) 36 will be described in detail.

  As shown in FIG. 2, the control circuit (control means) 36 uses a predetermined function (for example, a call function, an e-mail transmission / reception function, an Internet connection function, etc.) of the mobile phone device 10 stored in the RAM 10 described later. A first lock circuit (first lock means) 36A that restricts the use of a predetermined function based on the contents to be restricted is provided.

  Specifically, the operation of the first lock circuit 36A realizes a reduction in the call time by the call function, a decrease in the number of times of e-mail transmission by the e-mail transmission / reception function, a reduction in the internet connection time by the Internet connection function, etc. (Registered trademark).

  In addition, the control circuit 36 includes a first lock release circuit (first lock release means) 36E that releases the use restriction by the first lock circuit 36A. By the operation of the first lock release circuit 36E, the use restriction (the junior mode (registered trademark)) by the first lock circuit 36A is released, and a predetermined function of the mobile phone device 10 can be freely used.

  In addition, the control circuit 36 has a second lock that is changed to a use restriction having a content different from the content of the use restriction stored in the RAM 40 described later in a state where the use of a predetermined function is restricted by the first lock circuit 36A. A circuit (second lock means) 36B is provided. The operation restriction of the predetermined function is changed by the operation of the second lock circuit 36B.

  Specifically, examples of the contents of the changed usage restrictions include further reduction of the call time by the call function, further reduction of the number of times of email transmission by the email transmission / reception function, and further reduction of the Internet connection time by the Internet connection function. is there.

Further, the control circuit 36 includes a second lock release circuit (second lock release means) 36F that releases the use restriction by the second lock circuit 36B. By the operation of the second lock release circuit 36F, the use restriction by the second lock circuit 36B is released, and the contents of the use restriction by the first lock circuit 36A (the contents of the use restriction originally stored in the RAM 40) are restored. .

  In addition, the control circuit 36 controls the second lock circuit 36B after a predetermined period of time has elapsed since the second lock circuit 36B has changed the use restriction to a content different from the use restriction stored in the RAM 40. An automatic control circuit (automatic control means) 36G for automatically releasing the use restriction by the second lock circuit 36B is provided. By the operation of the automatic control circuit 36G, the use restriction by the second lock circuit 36B is released, and the contents of the use restriction by the first lock circuit 36A (the contents of the use restriction initially stored in the RAM 40) are restored.

  In addition, the control circuit 36 calculates a difference per predetermined period (or predetermined time) between the content of the use restriction stored in the RAM 40 from the beginning and the usage amount actually used by the user (calculating means) 36C. It has.

  Specifically, a value (difference) obtained by subtracting the call time actually talked by the user from the call time stored in advance in the RAM 40 or the actual transmission by the user from the number of times of e-mail transmission stored in the RAM 40 in advance. A value (difference) obtained by subtracting the number of times the electronic mail has been sent or a value (difference) obtained by subtracting the Internet connection time actually connected to the Internet by the user from the Internet connection time stored in advance in the RAM 40 is calculated by the arithmetic circuit 36C. Each is calculated.

  Furthermore, the control circuit 36 includes a correction circuit (correction means) 36D that adds the difference to the contents of the use restriction stored in the RAM 40.

  Specifically, for example, a value obtained by subtracting a call time actually spoken by the user from a call time stored in the RAM 40 in advance or a number of times of e-mail transmission stored in the RAM 40 in advance is actually transmitted by the user. A value obtained by subtracting the number of times of e-mail transmission or a value obtained by subtracting the Internet connection time actually connected to the Internet by the user from the Internet connection time stored in advance in the RAM 40 is stored in the RAM 40 in advance by the correction circuit 36D. Is added to the call time, the number of times of e-mail transmission, or the Internet connection time. As a result, if the difference becomes positive, the call time, the number of e-mail transmissions, and the Internet connection time stored in the RAM 40 in advance become longer than those at the beginning.

  Further, the RAM 40 stores contents for restricting the use of predetermined functions (for example, a call function, an e-mail transmission / reception function, an Internet connection function, etc.) of the mobile phone device 10. For example, a call time by a call function, an e-mail transmission frequency by an e-mail transmission / reception function, an internet connection time by an internet connection function, and the like are stored. The contents of these use restrictions can be freely set by the user, and can be changed as appropriate.

  A liquid crystal display 42 is connected to the control circuit 36. The display 42 displays the current time, the name of the communication partner, the telephone number, the contents of the e-mail, and the like.

An input unit 44 is connected to the control circuit 36. The input unit 44 includes a numeric keypad 48 for inputting a telephone number and the like, a call key 50 for operating a call start, a cut key 52 for operating a call end, a function key 54 for setting various functions, have. When the user operates the numeric keypad 48 and the function key 54, the first lock circuit 36A, the first lock release circuit 26E, the second lock circuit 36B, the second lock release circuit 36F, the automatic control circuit 36G, the arithmetic circuit 46C, the correction In addition to being able to operate the circuit 36D, it is possible to freely change the contents of the use restriction stored in advance in the RAM 40, and further to input and determine the contents of the use restriction changed by the operation of the second lock circuit 36B. can do.

  Next, a usage management method using the mobile phone device 10 according to the present embodiment will be described based on the flowchart shown in FIG.

  First, as shown in FIG. 3, the first lock circuit 36A determines whether or not a predetermined first lock number has been input by operating the numeric keypad 48 and the function key 54 of the mobile phone device 10 ( Step 100). When the first lock number is input, the first lock circuit 36A is activated (step 110), and the so-called junior mode (registered trademark) is set (step 120). In the junior mode (registered trademark), use of a predetermined function is restricted based on the content of the use restriction of the predetermined function of the mobile phone device 10 stored in the RAM 40 in advance. For example, the call time by the call function is shortened, or the number of times of e-mail transmission by the e-mail transmission / reception function is reduced, and further, the internet connection time by the internet connection function is shortened. Using this junior mode (registered trademark), the use of a predetermined function of the mobile phone device 10 can be managed.

  When the first lock number is not input by the user and the first lock circuit 36A determines that the first lock number is not input, the first lock circuit 36A does not operate.

  Next, the first unlocking circuit 36E determines whether or not the first unlocking number has been input (step 130). When the user operates the numeric keypad 48 and the function key 54 of the mobile phone device 10 to input the first unlock number, and the first unlock circuit 36E determines that the first unlock number has been input. Then, the first lock release circuit 36E is activated (step 140), and the locked state by the first lock circuit 36A is released (step 150). Thereby, the junior mode (registered trademark) is canceled.

  When the first unlocking number is not input by the user and the first unlocking circuit 36E determines that the first unlocking number is not input, the locked state by the first locking circuit 36A is released. Instead, the process moves to step 160 described later.

Next, the second lock circuit 36B determines whether or not a predetermined second lock number has been input by operating the numeric keypad 48 and the function key 54 of the mobile phone device 10 (step 160). When the second lock number is input, the second lock circuit 36B is activated (step 170), and the use restriction stored in the RAM 40 is stored in a state where the use of a predetermined function is restricted by the first lock circuit 36A. The usage restriction is changed to a content different from the content (step 180). The contents of the use restriction to be changed can be freely set by the user by operating the numeric keypad 48 and the function key 54.
For example, the usage amount permitted in the junior mode (registered trademark) (contents of usage restrictions of each function previously stored in the RAM 40) is compared with the usage amount actually used by the user, and the actual usage amount of the user is compared. Can be set so that the user can use as much as possible by operating the numeric keypad 48 and the function keys 54. The contents of the use restriction after the change are temporarily stored in the RAM 40.

In this way, usage restrictions such as the number of email transmissions in junior mode (registered trademark), telephone call time, and internet connection time are preset in advance, and the usage status is managed monthly. However, for example, when the number of e-mail transmissions, telephone call time, and internet connection time in a certain month are less than the initial setting values (junior mode (registered trademark) setting values), the second lock circuit 36B is activated. By doing so, it is possible to increase each of the above-mentioned usage amounts for the following month by that small amount. In this way, by operating the second lock circuit 36B, for example, the usage amount of a predetermined function per month can be made constant, and the usage fee can be made constant.

  Next, it is judged by the first unlocking circuit 36F whether or not the first unlocking number has been inputted (step 190). If it is determined by the first unlock circuit 36F that the first unlock number has been input, the second unlock circuit 36F is activated (step 200). In step 240, the lock state by the second lock circuit 36B is set. Canceled. As a result, the contents of the use restriction by the first lock circuit 36A (the contents of the use restriction stored in the RAM 40 at the beginning) are restored.

  If the first lock release number is not input by the user and the first lock release circuit 36F determines that the first lock release number is not input, the lock state by the second lock circuit 36B is released. Instead, the process moves to step 220 described later.

  Next, when the first unlocking number is not input by the user and the first unlocking circuit 36F determines that the first unlocking number is not input, the predetermined state is determined from the locked state by the second locking circuit 36B. Is determined by the automatic control circuit 36G (step 220). If it is determined that the predetermined period has elapsed, the automatic control circuit 36G is activated (step 230). The lock state by the second lock circuit 36B is released (step 240), and the lock state (the junior mode (registered trademark) state) by the first lock circuit 36A is restored. Thereby, even if a user does not perform predetermined | prescribed operation, it can return to the setting of junior mode (trademark) automatically.

  In the usage management method of the mobile phone device 10 of the present embodiment, the first lock number and the first unlock number may be the same number or different numbers.

  Next, a modified example of the usage management method of the mobile phone device 10 of this embodiment will be described. In addition, description of the step which overlaps with the usage management method of the mobile telephone apparatus 10 of 1st Embodiment is abbreviate | omitted suitably.

  As shown in FIG. 4, the first lock circuit 36 </ b> A is activated at step 110, and the junior mode (registered trademark) is set at step 120. In the setting of the junior mode (registered trademark), the user uses a predetermined function of the mobile phone device 10 for a predetermined period.

  Next, it is determined by the arithmetic circuit 36C whether or not a predetermined period has elapsed (step 300). When it is determined in step 300 that the predetermined period has elapsed, the content of the use restriction of the predetermined function of the mobile phone device 10 restricted by the operation of the first lock circuit 36A (the use stored in the RAM 40 in advance) The content of the restriction) and the usage amount that the user actually uses the predetermined function are compared by the arithmetic circuit 36C, and the difference is calculated (step 310).

  For example, a value (difference) obtained by subtracting a call time actually spoken by the user from a call time stored in advance in the RAM 40 or an electronically actually sent by the user from the number of times of e-mail transmission stored in the RAM 40 in advance. A value (difference) obtained by subtracting the number of times of mail transmission, or a value (difference) obtained by subtracting the Internet connection time actually connected to the Internet by the user from the Internet connection time stored in advance in the RAM 40 is calculated.

Next, the correction circuit 36D adds the difference to the contents of the use restriction stored in the RAM 40 in advance, and the use restriction contents stored in the RAM 40 in advance are corrected (step 320).

  Specifically, for example, the second lock circuit is calculated by subtracting the call time changed by the second lock circuit 36B from the call time stored in the RAM 40 in advance, or the number of times of e-mail transmission stored in the RAM 40 in advance. A value obtained by subtracting the number of times of e-mail transmission changed by 36B, or a value obtained by subtracting the internet connection time changed by the second lock circuit 36B from the internet connection time stored in advance in the RAM 40 is obtained in advance by the correction circuit 36D. It is added to the call time, the number of e-mail transmissions, or the Internet connection time stored in the RAM 40, respectively. As a result, if the difference becomes positive, the call time, the number of e-mail transmissions, and the Internet connection time stored in advance in the RAM 40 increase by the difference.

  Next, when the second lock number is input in step 330, the second lock circuit 36B is activated in step 340, and in step 350, the content of restriction on the use of a predetermined function is changed to the content after correction. Thereby, the user can use a predetermined function of the mobile phone device 10 under the use restriction of the content after the correction.

  After that, as in the usage management method of the mobile phone device 10 of the above embodiment, it is determined in step 360 whether or not the first unlock number has been input, and it is determined that the first unlock number has been input. Then, in step 370, the second lock release circuit 36F operates, and in step 380, the lock by the second lock circuit 36B is released.

  As described above, in the usage management method of the mobile phone device 10 according to this modification, even when the use of a predetermined function of the mobile phone device 10 temporarily decreases for a certain period, the user calculates the difference. Rather, the difference is calculated by the arithmetic circuit 36D, and the difference is added to the content of the use restriction stored in the RAM 40 by the correction circuit 36D to be corrected, thereby keeping the usage amount of the predetermined function of the user constant. be able to.

  In addition, when the first lock release number is input in the state where the lock is applied by the second lock means, the lock is not applied by the second lock means but is locked by the second lock means. In this state, when the first unlocking number is input, only a predetermined setting may be changed among the contents locked by the second locking unit while being locked by the second locking unit. .
