Stored in the memory card 27A.

  FIG. 3 is a functional block diagram showing an outline of the function of the CPU of the mobile phone according to one embodiment of the present invention together with information stored in the flash memory. Referring to FIG. 3, the CPU 21 specifies a communication control unit 51 that controls outgoing / incoming calls, an outgoing mail management unit 53 that transmits an electronic mail, an incoming mail management unit 55 that receives an electronic mail, and a call. A specific call detecting unit 57 for detecting a call, a time measuring unit 59 for measuring a call time, and a warning unit 61 for giving a predetermined warning are included.

  The flash memory 31 stores a transmission e-mail 81, a reception e-mail 83, history information 85, and a telephone directory 87. The telephone directory 87 includes a user record in which a telephone number as identification information is associated with a name as personal information of a user who owns the mobile phone to which the telephone number is assigned. The personal information is not limited to the name, but may be information that can identify the user who owns the mobile phone to which the telephone number is assigned. The user record is stored in the telephone directory 87 by being registered in advance by the user of the mobile phone 1.

  The transmission e-mail 81 is an e-mail transmitted by a transmission e-mail management unit 53 described later, and is stored in the flash memory 31 by the transmission e-mail management unit 53. The received e-mail 83 is an e-mail received by a received mail management unit 55 described later, and is stored in the flash memory 31 by the received mail management unit 55. The history information 85 includes a telephone number as identification information of the calling party of the specific call, and is stored in the flash memory 31 by the specific call detection unit 57 described later.

  The communication control unit 51 controls incoming and outgoing calls and incoming and outgoing e-mails. In making and receiving calls, the identification information of the communication partner is the telephone number assigned to the mobile phone of the communication partner, and in sending and receiving e-mail, the identification information of the communication partner is assigned to the telephone of the communication partner or the communication partner. E-mail address. The telephone includes a fixed telephone connected to PSTN (Public Switched Telephone Networks) and a mobile telephone connected to a wireless network.

  When the radio circuit 22 receives the incoming call signal from the base station, the communication control unit 51 outputs the telephone number included in the incoming call signal to the specific call detecting unit 57 as the telephone number of the called party. The caller telephone set may be set not to notify the telephone number assigned to the own apparatus, and in this case, the incoming call signal does not include the telephone number. When the incoming call signal does not include a telephone number, the communication control unit 51 outputs a non-notification signal indicating that the destination is not notified of the telephone number to the specific call detecting unit 57 instead of the telephone number. . When the communication control unit 51 detects that the user has pressed the off-hook key of the operation key 14 after receiving the incoming call signal, the communication control unit 51 connects the line with the other party's telephone through the base station, It becomes possible. Further, after the user of the mobile phone 1 directly inputs a telephone number into the operation key 14 or specifies user data in the telephone directory 87, the communication control unit 51 presses the off-hook key of the operation key 14 by the user. If this is detected, a call is made to the calling party's telephone through the base station, and if the calling party's telephone answers, the line with the calling party's telephone is connected, and a call can be made.

  The timer 59 measures the call time. The timing unit 59 connects the communication line with the telephone of the other party by pressing the off-hook key of the operation key 14 by the user and then presses the on-hook key of the operation key 14 or The time until the communication line is cut off by the telephone is counted. The timer unit 59 outputs the elapsed time (call time) since the start of timing to the warning unit 61.

  The transmitted mail management unit 53 transmits an electronic mail and manages the transmitted electronic mail. Specifically, processing for storing the transmitted e-mail, displaying and deleting the stored e-mail is executed. After the e-mail address is directly input to the operation key 14 by the user of the mobile phone 1 or the user data in the telephone directory 87 is designated, the user is assigned an operation for sending an e-mail out of the operation keys 14. If it is detected that the key has been pressed, an electronic mail and a transmission instruction are output to the communication control unit 51. The communication control unit 51 transmits an e-mail to the e-mail server through the base station.

  The received mail management unit 55 manages the email received by the communication control unit 51. Specifically, processing for storing received e-mail, displaying and deleting stored e-mail is executed. When an email is input from the communication control unit 51, the received mail management unit 55 stores the email in the flash memory 31. Further, when the received mail management unit 55 detects that the user is pressed among the operation keys 14 to which an operation for viewing received electronic mail is pressed, the received mail stored in the flash memory 31 is detected. An e-mail 83 is displayed on the LCD 15.

  The specific call detection unit 57 detects a specific call based on the telephone number input from the communication control unit 51 or the non notification signal. The specific call is a call based on an incoming call that uses a telephone number that is not registered in the telephone directory 87 in advance as a caller telephone number or a non-notified incoming call that does not notify the caller telephone number. When detecting a specific call, the specific call detection unit 57 outputs a signal indicating that the call is a specific call to the warning unit 61.

  When a telephone number is input from the communication control unit 51, the specific call detecting unit 57 searches the telephone directory 87 using the telephone number. If the user data including the telephone number input from the communication control unit 51 is included in the telephone directory 87, the specific call detecting unit 57 determines that the call based on the telephone number is not a specific call, but the communication control unit 51 If the user data including the telephone number input from is not included in the telephone directory 87, it is determined that the call based on the telephone number is a specific call. When the specific call detection unit 57 determines that the call based on the telephone number input from the communication control unit 51 is a specific call, the specific call detection unit 57 stores the telephone number as history information 85 in the flash memory 31.

  However, the specific call detecting unit 57 stores the telephone number in the flash memory 31 as the history information 85 even when the user data including the telephone number input from the communication control unit 51 is not included in the telephone directory 87. If it is, it is not determined as a specific call. Since the telephone number stored as the history information 85 is a call made by the user in the past based on the telephone number, the same telephone number is not repeated as a specific call. As a result, it is possible to avoid repeated warnings for calls based on incoming calls of the same telephone number without registering the telephone number in the telephone directory 87.

  In addition, when a non notification signal is input from the communication control unit 51, the specific call detection unit 57 determines that the call by the communication control unit 51 is a specific call. The specific call detection unit 57 determines that the call is a specific call when a non-notification signal is input from the communication control unit 51, but does not store the history information 85 in the flash memory 31 because the telephone number is unknown. Therefore, unnotified incoming calls include incoming calls from public phones, and incoming calls in which the telephone number of the calling party cannot be specified. The specific call detection unit 57 detects all non-notified incoming calls as specific calls.

  When a signal indicating that the call is a specific call is input from the specific call detection unit 57, the warning unit 61 is set in advance according to the call time input from the time measuring unit 59 being a predetermined time or more. The e-mail is stored in the flash memory 31 as a received e-mail 83. The predetermined e-mail is referred to herein as a warning e-mail, and includes, for example, a warning message “Please note that there are many frauds caused by telephones posing as children and grandchildren” in the subject or body. When the warning e-mail includes a warning message in the text, for example, “warning” or “caution” is added as a subject indicating that the e-mail is a warning e-mail.

  When newly received email 83 is stored, received email manager 55 notifies the user that an email has arrived. Similarly, when the warning e-mail is stored as the received e-mail 83, the received mail management unit 55 notifies the user that the warning e-mail has been received. For this reason, it is possible to notify the user that a warning email exists.

  Further, after the warning e-mail is stored in the flash memory 31 as the received e-mail 83, the received e-mail management unit 55 receives the e-mail browsing operation when the user inputs an operation for browsing the e-mail to the operation key 14. List the subject of. For this reason, if a warning email is stored, a warning email means is displayed so that the user can recognize that a warning email is present and by looking at the subject or body warning message It can be determined whether the specific call is an incoming call from a wire fraudster.

  Since the received e-mail is browsed after the specific call, the warning e-mail is browsed when the call ends or after a while. For this reason, a warning message can be notified to the user in a mental situation in which it can be calmly determined whether or not the specific call is made by a transfer fraudster. As a result, the user can calmly think and can confirm whether or not the specific call is a transfer fraudster, so that the probability of damage caused by fraud can be reduced.

  FIG. 4 is a flowchart illustrating an example of the flow of incoming call processing. The incoming call process is a process executed by the CPU 21 when the CPU 21 executes a warning program. Referring to FIG. 4, CPU 21 determines whether an incoming call has been detected (step S01). When the radio circuit 22 receives an incoming call signal from the base station, the incoming call is detected. The process waits until an incoming call is detected (NO in step S01). If an incoming call is detected (YES in step S01), the process proceeds to step S02. That is, the incoming call process is a process executed on condition that the mobile phone 1 receives an incoming call.

  In step S02, the caller telephone number of the called party is acquired. The radio circuit 22 acquires the telephone number included in the incoming call signal received from the base station as the telephone number of the called party. Then, it is determined whether or not the off-hook key of the operation key 14 has been pressed (step S03). If it is detected that the off-hook key has been pressed, the process proceeds to step S04. If not, the process ends. When the off-hook key of the operation key 14 is pressed, a line is connected to the wireless circuit 22 to enable a call.

  In step S04, it is determined whether or not the caller telephone number is not notified. If not notified, the process proceeds to step S09; otherwise, the process proceeds to step S05. In step S05, it is determined whether the caller telephone number is registered in telephone directory 87 or not. If a user record including the caller telephone number of the called party is registered in telephone book 87, the process proceeds to step S06; otherwise, the process proceeds to step S09.

  In step S06, the name associated with the caller telephone number of the called party acquired in step S02 is acquired from the telephone directory 87. Then, the name acquired in step S06 is displayed on LCD 15 (step S07), and the process proceeds to step S08.

  In step S08, it is determined whether the call has ended. Specifically, it is determined whether or not the on-hook key of the operation key 14 has been pressed, or whether or not the line to which the radio circuit 22 is connected has been disconnected. When the on-hook key of the operation key 14 is detected to be pressed or when the disconnection of the line to which the wireless circuit 22 is connected is detected, the process is terminated. Otherwise, the process enters a standby state and the call is continued.

  The process proceeds to step S09 when the caller telephone number of the called party is not registered in the telephone directory 87 or when the incoming call is a non-notification that does not notify the caller telephone number. In step S09, it is determined whether or not the caller telephone number of the called party is stored in the flash memory 31 as history information 85. If stored as history information 85, the process proceeds to step S08; otherwise, the process proceeds to step S10.

  In step S10, it is determined whether or not the call duration is greater than or equal to a threshold value T. If the call time is equal to or greater than threshold value T, the process proceeds to step S12; otherwise, the process proceeds to step S11. In step S11, it is determined whether or not the call has been terminated, as in step S08. If the call is over, the process ends. If not, the process returns to step S10.

  The process proceeds to step S12 when the caller telephone number of the called party is not registered in the telephone directory 87, or when the incoming call is a non-notification that does not notify the caller telephone number, and the call time is the threshold. This is the case of the value T or more, and this call is a specific call. In step S12, when the telephone number is acquired in step S02, the telephone number is stored in the flash memory 31 as history information 85. It is not memorized when not notified. The incoming call history may be stored as a history so as to be distinguished from the incoming telephone number of a normal call that is not a specific call by adding a mark indicating that the call is a specific call.

  In the next step S13, a warning message is displayed on the LCD 15. Moreover, you may make it sound a warning sound. Then, a warning email is generated (step S14), and the generated warning email is set as a received mail. The warning e-mail includes a warning message “Please note that there are many frauds caused by telephones posing as children and grandchildren” in the subject or body. When the warning email includes a warning message in its body, “Warning” or “Caution” is included in the subject indicating that it is a warning email.

  In the next step S15, the warning email generated in step S14 is stored in the flash memory 31 as a received email. Thus, the user is notified that the e-mail has been received, and the warning e-mail is displayed when the user inputs an operation for browsing the incoming e-mail.

  In step S16, it is determined whether or not the telephone call is terminated as in step S08. The process waits until the call ends, and when the call ends, the process ends.

  As described above, the mobile phone 1 according to the present embodiment is a call based on an incoming call that uses a telephone number that is not registered in the telephone directory 87 in advance as a caller telephone number or an unnotified incoming call that does not notify the caller telephone number. Is detected as a specific call, and a predetermined e-mail is set as an incoming mail in response to the call time of the specific call being equal to or longer than a predetermined time. Calls from wire fraudsters are often specific calls longer than a predetermined time, and the user can be notified by e-mail that the call is from a wire fraudster. In addition, since e-mail is viewed after a specific call, the user will be notified when the call ends or after some time has passed, so the specific call is made by a transfer fraudster. In a situation where it is possible to calmly determine whether or not there is, a warning message can be notified to the user.

  Further, the caller telephone number of the specific call is stored as history information 85, and the specific call is detected on the condition that the same telephone number as the incoming caller telephone number is not included in the history information. For this reason, it is possible to prevent a user from being notified of uselessness by repeatedly not receiving an e-mail based on a call based on an incoming call of the same telephone number.

  Furthermore, since a predetermined warning message is displayed, it is possible to notify the user that the incoming call is from a wire fraudster during a call.

<Modification>
In the embodiment described above, the mobile phone 1 is processed as a received e-mail without transmitting the warning e-mail to the e-mail server. In the mobile phone 1 according to the modification, a warning electronic mail is transmitted to the own device. Specifically, the mobile phone 1 according to the modification generates a warning e-mail in which an e-mail address assigned to the device is set as a destination address, and transmits the warning e-mail to the e-mail server.

  FIG. 5 is a functional block diagram showing an outline of functions of the CPU of the mobile phone according to the modification together with information stored in the flash memory. Referring to FIG. 5, the difference from the functional block diagram shown in FIG. 3 is that warning unit 61 is changed to become warning unit 61A. Since other functions are the same as those shown in FIG. 3, the description thereof will not be repeated here. When a signal indicating that the call is a specific call is input from the specific call detection unit 57, the warning unit 61A sends a warning e-mail in response to the call time input from the time measuring unit 59 being a predetermined time or more. The generated warning e-mail is output to the outgoing mail management unit 53. The warning e-mail includes, for example, a warning message “Please note that fraud due to telephones posing as children and grandchildren is frequently occurring” in the subject or body, and is assigned to the mobile phone 1 that is the device itself as a destination. An email address is set. When the warning email includes a warning message in the text, for example, “warning” or “caution” is added as a subject indicating that the warning email is a warning email.

  Since the warning email is output to the outgoing mail management unit 53, the outgoing email management unit 53 transmits the warning email to the email server in response to the warning email input from the warning unit 61A. For this reason, the warning email is included in the email received by the received mail management unit 55 from the email server after the warning email is transmitted. When the received e-mail is received by the received e-mail management unit 55, the user is notified of the incoming e-mail, so that the user can be notified that the e-mail is present. Further, after the warning e-mail is stored in the flash memory 31 as the received e-mail 83, the received e-mail management unit 55 displays the subject displayed when the operation for browsing the e-mail is input to the operation key 14 by the user. The subject of the alert email is included in the list. For this reason, the user can recognize that there is a warning email, and can recognize that the specific call is an incoming call from a wire fraudster by looking at the warning message in the subject or text.

  FIG. 6 is a flowchart illustrating an example of the flow of incoming call processing in the modification. Referring to FIG. 6, the difference from the incoming call processing shown in FIG. 4 is that step S14 and step S15 are changed to step S14A and step S15A, respectively. The other processes are the same as those shown in FIG. 4, and therefore description thereof will not be repeated here.

  In step S14A, a warning email is generated. The warning e-mail generated here contains a warning message “Please note that there are many frauds caused by telephones disguised as children and grandchildren” in the subject or body, and is assigned to the mobile phone 1 in the modification as the destination. Set e-mail address. When the warning email includes a warning message in the text, for example, “warning” or “caution” is added as a subject indicating that the warning email is a warning email. In step S15A, the warning email generated in step S14A is transmitted to the email server. In this example, the e-mail address assigned to the mobile phone 1 that is the device itself is set as the destination of the warning e-mail. However, a pre-registered e-mail address may be set. For example, an e-mail address assigned to a user, relative, or acquaintance may be set.

  Since the mobile phone 1 according to the modified example transmits a warning email addressed to itself to the email server, it can receive the warning email generated by itself and store it in the flash memory 31 as the received email 83. Can do. Furthermore, since the user is notified of the incoming e-mail, the user can be notified that a warning e-mail exists. Further, after the warning e-mail is stored in the flash memory 31 as the received e-mail 83, the received e-mail management unit 55 receives the e-mail browsing operation when the user inputs an operation for browsing the e-mail to the operation key 14. List the subject of your alert email. For this reason, the user can recognize that there is a warning email, and can recognize that the specific call is an incoming call from a wire fraudster by looking at the warning message in the subject or text.

  Since the received email is viewed after a specific call, the warning email will be viewed at the end of the call or after a while, so the specific call is made by a transfer fraudster. It is possible to notify the user of a warning message in a situation where it can be determined calmly whether or not. For this reason, since the user can calmly think and can confirm whether or not the specific call is a transfer fraudster, the probability of damage caused by fraud can be reduced.

  In the above-described embodiment, the mobile phone 1 has been described as an example of the communication device. However, the mobile phone 1 is controlled with a warning method or a warning method for executing the processes shown in FIGS. 4 and 6. It goes without saying that the invention can be understood as a warning program for causing the CPU 21 to execute.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
