  The radio unit 180 includes a reception unit 181 that performs a radio signal reception operation via the antenna 183, and a transmission unit 182 that performs a radio signal transmission operation via the antenna 183.

  The receiving unit 181 demodulates the received radio signal and outputs the demodulated radio signal to the control unit 190.

  Based on the demodulated radio signal sent from the receiving unit 181, the control unit 190 causes the sounding unit 140 to perform a sounding operation (output the voice of the other party on the call) or display it on the display unit 120. The operation (display of the telephone number of the other party of the call or display indicating that the call is in progress) is performed.

  The transmission unit 182 modulates the voice signal generated by the control unit 190 based on the voice input from the reception unit 140 or the control signal transmitted by the control unit 190 and converts the modulated signal into a radio signal, and transmits the radio signal via the antenna 183. Is sent to the outside.

  As described above, the mobile phone device 100 can execute communication functions such as a call with another phone, transmission / reception of an e-mail, connection to the Internet, etc., when the wireless unit 180 executes wireless communication. It has become.

  As shown in FIG. 1, the control unit 190 inputs a central processing unit (CPU) 191, a first memory 192, a second memory 193, and various instructions and data to the central processing unit 191. An input interface 194 for outputting, an output interface 195 for outputting a result of processing executed by the central processing unit 191, a central processing unit 191, a first memory 192, a second memory 193, an input interface 194, and an output interface The bus 196 is connected to the bus 195.

  The second memory 193 stores various data and parameters and provides an operating area for the central processing unit 191. That is, data temporarily required for the central processing unit 191 to execute a program. Is stored.

  The central processing unit 191 reads a program from the first memory 192 and executes the program. That is, the central processing unit 191 operates according to a program stored in the first memory 192, and operates the operation unit 110, the display unit 120, the sound generation unit 130, the reception unit 140, the power supply unit 150, the GPS unit 160, the commuter pass function unit. Various control operations including control of operations of 170 and the wireless unit 180 are executed.

  FIG. 2 is a functional block diagram of the central processing unit 191 that is a component of the control unit 190.

  As shown in FIG. 2, the central processing unit 191 functionally includes a behavior pattern recording unit 191A, a standard behavior pattern extraction unit 191B, a behavior pattern determination unit 191C, and a control execution unit 191D. ing.

  The behavior pattern recording unit 191A creates user behavior data (details of behavior data will be described later) of the mobile wireless communication device 100 and stores the created behavior data in the second memory 193, for example. Alternatively, instead of accumulating in the second memory 193, it is also possible to transmit the behavior data to a server for data backup and accumulate the behavior data in the server.

  The standard behavior pattern extraction unit 191B, for example, the standard behavior pattern of the user of the mobile phone device 100 based on behavior data stored in the second memory 193 or the data backup server (for details of the standard behavior pattern, see FIG. (To be described later).

  The behavior pattern determination unit 191C compares the standard behavior pattern with the current user behavior pattern, and determines whether or not the current user behavior pattern deviates from the standard behavior pattern.

  When the behavior pattern determination unit 191C determines that the current user behavior pattern is out of the standard behavior pattern, the control execution unit 191D determines which one of the first control processing and the second control processing. Do one or both.

  The first control process includes a process for locking the operation of the portable wireless communication apparatus 100. By carrying out this first control process, a mobile phone such as input of data or commands to the mobile phone device 100 via the operation unit 110, display of various data on the display unit 120, communication with other phone devices, etc. All operations of the device 100 are stopped.

  The second control process includes a process for erasing data stored in the second memory 193. In the second control process, when the mobile phone device 100 includes a data storage memory in addition to the second memory 193, data is erased from all the data storage memories.

  It is possible for the user of the mobile phone device 100 to determine in advance which of the first control process and the second control process is performed, or whether both are performed. This can be specified by inputting a command for specifying one or both of the first control process and the second control process to the control unit 190 via the operation unit 110. In this case, the user of the mobile phone device 100 can change the designation at any time.

  Alternatively, at the time of manufacturing the mobile phone device 100, it is also possible to input to the control unit 190 which one of the first control process and the second control process is to be performed, or both. .

  Next, behavior data of the user of the portable wireless communication device 100 created by the behavior pattern recording unit 191A will be described.

  FIG. 3 shows an example of action data of the user of the portable wireless communication device 100 created by the action pattern recording unit 191A.

  For example, when the user of the mobile phone device 100 passes a railway station using the commuter pass function unit 170 of the mobile phone device 100, the behavior pattern recording unit 191A displays the passing station and the passing time, for example, the second memory. Store in 193.

  For example, on Monday, March 3, 2008, it is stored in the second memory 193 that the user of the mobile phone device 100 enters the A station at 8:00 and leaves the B station at 8:50. Further, on the same day, it is stored in the second memory 193 that the user of the mobile phone device 100 enters the B station at 18:30 and leaves the A station at 19:25.

  Further, when the user of the mobile phone device 100 makes a call, the action pattern recording unit 191A uses the second memory 193 to determine the start time (call recording) of the call, the distinction between transmission and reception, the used base station, and the like. Is remembered.

  The passage time of the railway station and the call start time are stored in chronological order.

  Although not shown in FIG. 3, the behavior pattern recording unit 191 </ b> A uses the GPS unit 160 to determine the second location of the user of the mobile phone device 100 at a predetermined time (for example, every 30 minutes). It can also be stored in the memory 193.

  Next, the standard behavior pattern extracted by the standard behavior pattern extraction unit 191B will be described below.

  FIG. 4 shows an example of a standard behavior pattern created by the standard behavior pattern extraction unit 191B.

  The standard behavior pattern of the user of the mobile phone device 100 is extracted based on the behavior data stored in the second memory 193 or the data backup server.

  In the behavior data of the user of the mobile phone device 100 shown in FIG. 3, a round trip between the station A and the station B is performed every day at a relatively fixed time. On the other hand, the time of a call by the mobile phone device 100 is not constant in time. Also, the base station used for the call is not constant.

  For this reason, the standard behavior pattern extraction unit 191B recognizes the round trip between the station A and the station B as an event periodically performed by the user of the mobile phone device 100, and the round trip between the station A and the station B. Is set as the standard behavior pattern.

  Specifically, the standard behavior pattern extraction unit 191B allows the user of the mobile phone device 100 to enter station A between 7:45 and 8:15 as an expected time, and from 8:35 as an expected time. Leaving B station at 9:05, and then entering B station between 18:00 and 19:00 as expected time, and between 18:50 and 19:50 as expected time This standard behavior pattern is stored in the second memory 193 as having a standard behavior pattern of leaving station A.

  Note that user behavior data may vary greatly depending on the day of the week. For example, when the user is a company employee working for a company, the action data from Monday to Friday and the action data on Saturday and Sunday often differ greatly. In such a case, two standard behavior patterns can be created: a standard behavior pattern that is applied from Monday to Friday and a standard behavior pattern that is applied only on Saturday and Sunday.

  In addition, if the user's behavior data varies greatly from week to week, such as Saturday and Sunday, and regularity cannot be found, it is possible not to create a standard behavior pattern for Saturday and Sunday. is there.

  Or when the regularity of a user's action data changes for every day of the week, it is also possible to create a standard action pattern for every day of the week. For example, the first standard behavior pattern may be applied for Monday, and the second standard behavior pattern may be applied for Tuesday.

  Further, the standard behavior pattern extraction unit 191B extracts a standard behavior pattern based on behavior data for a predetermined number of days (for example, behavior data for 15 days), and the standard behavior pattern for each number of days. Can be updated sequentially.

  FIG. 5 is a flowchart showing the operation of the mobile phone device 100 as the mobile wireless communication terminal device according to the present embodiment.

  First, the behavior pattern recording unit 191A of the control unit 190 creates behavior data of the user of the portable wireless communication device 100 as shown in an example in FIG. 3 (step S101).

  For example, the created behavior data is stored in the second memory 193, or the behavior data is transmitted to a data backup server and stored in the server (step S102).

  In addition, when accumulating action data in the second memory 193, in order to ensure a backup of the action data, the control execution unit 191D uses the predetermined action data accumulated in the second memory 193 so far. The data is transmitted to the backup server (step S103).

  For example, the second memory 193 stores the frequency of behavior data backup (for example, once per hour), and the control execution unit 191D transfers the behavior data to the data backup server according to the frequency. Send.

  Next, the standard behavior pattern extraction unit 191B of the control unit 190 is based on the behavior data stored in the second memory 193 or the data backup server, as shown in FIG. 100 standard user behavior patterns are extracted (step S104).

  Next, the behavior pattern determination unit 191C compares the standard behavior pattern with the current user behavior pattern, and whether or not the current user behavior pattern is out of the standard behavior pattern range, that is, the current user behavior. It is determined whether or not the pattern deviates from the standard behavior pattern (step S105).

  For example, the case where the current user behavior pattern deviates from the standard behavior pattern is as follows.

(1) When the user of the mobile phone device 100 does not get on and off at one or both of the A station and the B station at the expected time. (2) The user of the mobile phone device 100 gets on and off at a station other than the A station and the B station at the expected time. Case (3) When the user of the mobile phone device 100 gets on and off at the stations A and B at a time other than the expected time

  When it is determined that the current user behavior pattern is not deviated from the standard behavior pattern (NO in step S105), the first control process and the second control process described later are not performed.

  When the behavior pattern determination unit 191C determines that the current user behavior pattern is out of the standard behavior pattern (YES in step S105), the control execution unit 191D performs the first control process (cell phone device). One or both of 100 operation lock and second control processing (data deletion) is performed (step S106).

  According to the mobile phone device 100 as the mobile wireless communication terminal device according to the present embodiment, the following effects can be obtained.

  When the behavior pattern of the user of the mobile phone device 100 deviates from the standard behavior pattern, that is, when the user of the mobile phone device 100 performs a behavior different from the daily life, the user of the mobile phone device 100 It is assumed that the risk of losing 100 is relatively large.

  In such a case, according to the mobile phone device 100 as the mobile wireless communication terminal device according to the present embodiment, it is automatically detected that the action pattern of the user of the mobile phone device 100 is out of the standard action pattern. As a necessary measure for preventing data leakage due to loss of the mobile phone device 100, one or both of locking the operation of the mobile phone device 100 and erasing data stored in the second memory 193 are performed. To do.

  These measures are automatically performed by the mobile phone device 100 without requiring any action by the user of the mobile phone device 100.

  For this reason, it is possible to reliably prevent the data outflow due to the loss of the mobile phone device 100.

  In the present embodiment, the mobile wireless communication terminal device according to the present embodiment is configured as the mobile phone device 100. However, the implementation object of the mobile wireless communication terminal device according to the present embodiment is limited to the mobile phone device 100. Not. For example, the portable wireless communication terminal apparatus according to the present embodiment can be applied to a PHS (Personal Handy-phone System). The same applies to the modified examples and other embodiments described below.

(Modification 1 of the first embodiment)
FIG. 6 is a flowchart showing an operation in the first modification of the portable wireless communication terminal device according to the first embodiment of the present invention.

  In the flowchart of the mobile phone device 100 shown in FIG. 5, when the behavior pattern determination unit 191C determines that the current user behavior pattern is out of the standard behavior pattern (YES in step S105), The control execution unit 191D performs one or both of the first control process (locking operation of the mobile phone device 100) and the second control process (erasing data) (step S106).

  In the first modification, when the behavior pattern determination unit 191C determines that the current user behavior pattern is out of the standard behavior pattern (YES in step S105), the control execution unit 191D displays the display unit. A warning is displayed at 120 (step S107).

  The warning includes, for example, a request for a response to the user of the mobile phone device 100 and, if there is no response, the first control process or the second control process is executed.

  Instead of the display on the display unit 120, the message having the above contents may be issued via the sound generation unit 130, and both the display on the display unit 120 and the message transmission via the sound generation unit 130 may be performed. .

  After issuing the warning, the control execution unit 191D determines whether or not there is a response from the user of the mobile phone device 100 (step S108).

  When there is a response from the user of the mobile phone device 100 (YES in step S108), the control execution unit 191D does not execute the first control process and the second control process. In this case, the mobile phone device 100 continues to operate.

  When there is no response from the user of the mobile phone device 100 (NO in step S108), the control execution unit 191D performs the first control process (locking operation of the mobile phone device 100) and the second control process (data (Erase) is performed (step S106).

  The case where there is no response from the user of the mobile phone device 100 is, for example, the following case.

(1) When there is no input from the user of the mobile phone device 100 via the operation unit 110 within a predetermined time (for example, 1 minute) (2) When a response is requested by encryption, it is predetermined When the user of the cellular phone device 100 does not input the encryption within the specified time (for example, 1 minute) via the operation unit 110. (3) When a response is requested by encryption, a predetermined time ( For example, when a cipher is input from the user of the mobile phone device 100 via the operation unit 110 within one minute), but the cipher is not a genuine cipher.

  As described above, according to the first modification, even when it is determined that the current behavior pattern of the user of the mobile phone device 100 is out of the standard behavior pattern, the user responds to the warning. If there is, that is, if there is no possibility that the user loses the mobile phone device 100, the first control process or the second control process is not performed unnecessarily. For this reason, it is possible to prevent the operation of the mobile phone device 100 from being locked or erasing data against the user's will.

(Modification 2 of the first embodiment)
FIG. 7 is a flowchart showing an operation in the second modification of the portable wireless communication terminal device according to the first embodiment of the present invention.
