Description

  The present invention relates to a mobile phone device, and more particularly to a technology that is effective for use as a countermeasure against overuse of a mobile phone device for a minor group.

Mobile phone devices are widespread and are owned by many people, from children to adults. As a problem that has occurred, there is a problem of high charges due to excessive use of mobile phones. As one method for dealing with this, a mobile phone has been proposed in which a limit mode is provided in a mobile phone, and a limit item can be set by a 4-digit password and password. Japanese Patent Laid-Open No. 2002-281148 is an example of a mobile phone device in which the function is restricted from another telephone when it is lost or stolen.
JP 2002-281148 A

  A method of setting a limit mode in the mobile phone device main body and setting it with a password and a password is simple because it can be realized by a single mobile phone device. However, the PIN or password may be stolen or analyzed by trial and error, and the limit mode may be canceled. Further, it is necessary to input a password or password every time the limit mode is set, and convenience is impaired. Therefore, I thought about memorizing a specific phone number instead of a personal identification number and password, and restricting each function from the specific phone number, or releasing the restriction.

  An object of the present invention is to provide a mobile phone device that prevents overuse of minors and the like. The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  The outline of a typical invention among the inventions disclosed in the present application will be briefly described as follows. That is, the radio wave received by the antenna is converted by the RF unit, the data is transmitted / received to / from the RF unit by the transmission / reception control unit, the specific telephone number is stored by the telephone number recording unit, and the specific number is stored by the telephone number comparison unit. The phone number and the received phone number are compared to detect a match, information / software that can be rewritten is stored in the storage unit, and calls and various services are executed by the call / service execution unit based on the information / software Part or all of functions executed by the call / service execution unit by accessing the storage unit through a communication line from a telephone device having the specific telephone number to a mobile phone device by a match signal of the telephone number comparison unit Can be restricted.

  By restricting each function of the cellular phone by using the stored phone number of the parent or the like as a cipher, it is possible to prevent a charge of a large fee due to overuse of the cellular phone device by a minor or the like. Even if a mobile phone is lost, it is possible to forcibly prevent data theft.

  FIG. 1 shows a schematic block diagram of an embodiment of a cellular phone device according to the present invention. Reference numeral 101 denotes an antenna that receives and transmits radio waves. The RF unit 102 is a high-frequency interface that inputs received radio waves or outputs transmitted radio waves. The transmission / reception control unit 103 performs signal processing to be transmitted / received to / from the RF unit 102. For example, the transmission / reception control unit 103 transmits the received signal to the call / service execution unit 104 and sends the other party's telephone number to the reception number comparison unit 105. Tell.

  The call / service execution unit 104 performs a reception operation corresponding to the reception signal corresponding to the information / software stored in the rewritable information / software storage unit 107. In this embodiment, a telephone number storage unit 106 is provided in order to prevent overuse by minors and the like. The telephone number recording unit 106 registers the telephone number of a person who manages the usage status of such a cellular phone device such as a parental authority at the time of the contract. A plurality of such telephone numbers can be registered with a priority order if desired. This telephone number cannot be rewritten or deleted by the mobile phone device itself having the telephone number recording unit 106. The received number comparison unit 105 compares the received telephone number with the telephone number stored in the telephone number storage unit 106 to form a signal transmission path shown in the form of a switch and transmit / receive Access from the control unit 103 to the storage unit 107 is enabled. The mobile phone device includes a microphone for voice input, a speaker for outputting a received voice signal, a key unit for inputting a telephone number, characters, and the like, and a display unit, which are included in the communication / service execution unit 104. I want you to understand that

  FIG. 2 shows a basic information structure of the storage unit. An example is shown in which the telephone number storage unit 106 of FIG. 1 and the rewritable information / software recording unit 107 are configured as one storage unit. The storage unit in FIG. 3 is divided into a telephone number storage unit 201, a rewritable information storage unit 204, and a software storage unit 211. The telephone number storage unit 201 is allowed only read access by its address.

  The structure of the telephone number storage unit 201 includes a priority order unit 202 and a telephone number unit 203 corresponding thereto. When restricting each function, the condition stored from the telephone number with the highest priority is given priority. The rewritable information storage unit 204 has a plurality of structures each including information including a registration number (No.) 205, a priority 206, an operation condition 207, a numerical value 208, an operation content 209, and a state 210. The priority 206 stores the priority 202 of the telephone numbers used for storage. As the type of the operation content 209, it is possible to set functions of the mobile phone such as contact for making contact when the operation condition exceeds a set value, outgoing call prohibition, mail prohibition, forced power-off, and the like. That is, in the software storage unit 211 shown in the figure, according to the operation content 212 and the program content 213, the charge communication is performed as the operation content when the call charge> numerical value. Call prohibition is performed when the call charge is greater than a numerical value.

  In the rewritable information storage unit 204, the state 210 is a state indicating whether or not the function restriction is being executed, and the state stored from the telephone number with the higher priority order to the telephone number with the lower priority order can be changed. However, the state stored from the lower priority telephone number to the higher priority telephone number cannot be changed. The rewritable software storage unit 211 has an operation content 212 and a program content 213.

  FIG. 3 shows a flowchart of one embodiment of the basic algorithm. In step 301, radio waves are received from the antenna 101. In step 302, information is extracted from the RF unit 102 and sent to the transmission / reception control unit 103. In step 303, the transmission / reception control unit 103 acquires the telephone number of the transmission source. In step 304, the telephone number comparison unit 105 compares the transmission source telephone number with the telephone number stored in the telephone number storage unit 105. When the telephone number of the transmission source matches the telephone number stored in the telephone number storage unit 105, the information / software storage unit 107 can be referred to / changed / erased / executed in step 305. . If the transmission source is not the stored telephone number, in step 306, the call / service execution unit executes the call / service.

  FIG. 4 shows a flowchart of an embodiment of the detailed algorithm. In this embodiment, an example of access to the storage unit is shown. In step 401, information input / reference / change / erase / execution / cancel is acquired as an instruction from the transmission source. In step 402, input / reference / change / erase / execution / cancel branches. In the case of input, it is determined in step 403 whether there is a storage unit available. If the storage unit is free, information from the transmission source is stored in step 404. That is, No. 1 to No. 3 of the registration number 205 assigned to the rewritable information storage unit 204 of FIG. 2 are checked, and when there is a vacancy, there are priority rank 206, operating condition 207, numerical value 208, Input the operation content 209 and the like.

  In the case of reference, a registration number 205 (any of No. 1 to No. 3) to be referred to in step 405 is acquired. For example, when referring to the registration number No. 1, it is determined in step 406 whether information exists in the registration number (No. 1). If the information of the number (No. 1) exists, the information (priority 206, operation condition 207, numerical value 208, operation content 209 and state 210) is returned to the transmission source in step 407.

  In the case of change, a registration number 205 (any one of No. 1 to No. 3) is acquired in step 408. For example, when the registration number No. 1 is changed, it is determined in step 409 whether the information of the registration number (No. 1) exists. If the information of the registration number (No. 1) exists, in step 410, the priority 206 of the information of the registration number (No.) is compared with the priority of the telephone number of the transmission source. If the priority order of the transmission source is high, the registration number (No. 1) information is changed in step 411. If the sender has a low priority, the change is invalid. In the case of erasure / execution / cancellation, the same processing as the above change is performed.

  In the case where the cellular phone device is stolen or lost, the above-mentioned function such as change or deletion is used to connect the other registered phone device to the above-mentioned stolen or lost cellular phone device. By disabling the power-on operation, or by erasing or destroying the software itself such as outgoing calls, the outgoing functions such as telephone and mail are forcibly stopped, and the usage fee etc. by a malicious third party is charged to the mobile phone device. It is possible to prevent the user from being charged.

  FIG. 5 shows a flowchart of an embodiment of an operation algorithm inside the mobile phone device. In step 501, the variable i is set to zero. In step 502, it is determined whether information is stored. If the information is stored, it is determined in step 503 whether the state of the information is being executed. If the status of the information is being executed, it is determined in step 504 whether the numerical value inside the terminal exceeds the operating condition and the numerical value. If the numerical value is exceeded, the operation content is executed in step 505. In step 506, the variable i is incremented by one. In step 507, it is determined whether the value of i exceeds the maximum value of the storage unit. If not, the process returns to step 502 to perform the next process. When the maximum value of the storage unit is exceeded, the operation is terminated. That is, it is determined that the use exceeds the specified upper limit value, and outgoing calls, incoming mails, and the like are restricted corresponding to each information.

  Compared to the conventional method of setting a limit mode on the mobile phone body and setting it with a password and password, in the present invention, a specific phone number is stored instead of the password and password, and the specific phone number is used. Each function is restricted or released, so each function of the mobile phone device can be restricted by the stored phone number and operating conditions to prevent excessive charges due to overuse of the mobile phone device. I can do it. In addition, when the mobile phone device is lost, the data in the mobile phone device can be prevented from being stolen by forcibly turning off the power from outside.

  Although the invention made by the inventor has been specifically described based on the above embodiment, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. For example, the rewritable information / software recording unit, the structure of the information stored therein, and the procedure for inputting / referring / changing / erasing / executing / stopping the information can take various embodiments. it can. The present invention can be widely used for mobile phone devices.
