[Control action when emergency broadcast or emergency information is received]
2 to 4 show operational flowcharts when the mobile phone terminal according to the present embodiment receives emergency broadcast or emergency information inside or outside the disaster area. The control processes in the flowcharts of FIGS. 2 to 4 are processes executed mainly by the control unit 20 based on the terminal operation control program at the time of receiving the emergency broadcast or emergency information stored in the memory 29. is there.

  In the flowchart shown in FIG. 2, the control unit 20 determines whether the television broadcast receiving unit 23 or the radio broadcast receiving unit 25 has received an emergency broadcast or the communication circuit 21 is in an emergency from the cellular phone network as the process of step S1. Whether or not information has been received is constantly monitored, and if an emergency broadcast or emergency broadcast is not received (No), the processing of this flowchart is restored, while an emergency broadcast or emergency broadcast is received. Is determined to have been received (Yes), the process proceeds to step S2. Note that the mobile phone terminal of the present embodiment is automatically turned on by receiving an emergency broadcast signal or emergency information even if the power is turned off, for example.

  When the process proceeds to step S2, the control unit 20 controls the communication circuit 21 to automatically access the information providing center on the mobile phone network, or the web by the URL registered in the memory 29. The above information providing site is automatically accessed, and the disaster occurrence information and the disaster location information on the emergency broadcast or emergency information are automatically obtained from the information providing center or the information providing site. Both the access to the information provision center and the automatic access to the information provision site may be performed, and when the disaster occurrence information and the disaster location information can be automatically obtained from either one, the other is automatically accessed. It may not be performed. In step S2, the control unit 20 recognizes a base station area corresponding to the current location of the terminal from the nearest base station, or controls the GPS unit 44 to determine the current location of the mobile phone terminal. By searching and using the above-mentioned disaster location information and current location information, whether or not the current location information of the terminal is substantially the same as the disaster location information, that is, within the area where the emergency occurred It is determined whether or not it exists, or in other words, whether or not the user of the terminal is in the disaster area. When the control unit 20 determines that the terminal is present in the emergency area in the process of step S2, the control unit 20 proceeds to the process flow in the emergency area shown in FIG. If it is determined that the terminal exists outside the emergency area, the process proceeds to the processing flow outside the emergency area shown in FIG.

  When proceeding to the processing flow in the emergency area in FIG. 3, the control unit 20 performs time counting by the clock unit 30 and checks whether there is an output from the operation unit 28 as a process of step S <b> 10. It is determined whether there is no input for a certain period of time. If the control unit 20 determines in step S10 that no input has been made from the user even after a predetermined time has elapsed, the control unit 20 proceeds to step S14. If it is determined that any input has been made, the process proceeds to step S11.

  If it is determined in step S10 that some input has been made by the user before the predetermined time has passed and the process proceeds to step S11, the control unit 20 accesses the safety confirmation site on the display of the display unit 27, for example. A message asking whether or not to perform the operation is displayed, and when an instruction input for permitting access to the safety confirmation site is received from the user via the operation unit 28, a URL whose URL is registered in advance in the memory 29 is received. The communication circuit 21 is automatically accessed by controlling the communication circuit 21. Further, after prompting the user to input safety information, the process proceeds to step S12. Further, in step S11, the control unit 20 activates a safety information contact e-mail creation screen addressed to an address set and registered in advance in the memory 29 for safety confirmation, prompts the user to input safety information, When the creation of the e-mail is completed and the user inputs a transmission instruction for the e-mail via the operation unit 28, the process proceeds to step S12. It should be noted that both the automatic access to the safety confirmation site and the activation of the safety notification e-mail creation screen in step S12 may be performed, or only one of them may be performed.

  In step S12, the control unit 20 displays, for example, a user authentication screen for requesting the user to input a personal identification number on the display of the display unit 27, and when the correct personal identification number is input by the user (user authentication). When the personal identification is confirmed), the process proceeds to step S13. On the other hand, when the entered personal identification number is not correct or the personal identification number is not entered even after a certain period of time (user authentication is not confirmed). If so, the process proceeds to step S14. The user authentication in step S12 may be biometric authentication using a fingerprint, finger vein pattern, retinal vein pattern, iris pattern, or the like. Of course, in that case, the mobile phone terminal is provided with a device for performing biometric authentication.

  When the processing proceeds to step S13, the control unit 20 transmits the user-authenticated safety information to the safety confirmation site accessed in step S11. Moreover, the control part 20 transmits the email for safety information notification produced in step S11. In addition, when an email for inquiring about safety from a plurality of destinations is stored in the email reception folder or mail server of the terminal, the control unit 20 sends a safety information email from the user. Under the instruction, the electronic mail is also sent to the addresses of the plurality of destinations. When only automatic access to the safety confirmation site is performed in step S11, only the safety information is transmitted to the safety confirmation site in step S13, and the safety information is transmitted in step S11. When only the creation of the mail is being performed, only the electronic mail is transmitted in step S13. After the process of step S13, the process returns to the flowchart of FIG.

  On the other hand, if it is determined in step S10 that no input has been made by the user even after a predetermined time has passed and the process proceeds to step S14, the control unit 20 sets the memory 29 in advance for safety confirmation. To the registered address, the safety information that has been created in advance or stored in the memory 29 as initial information, the current position information obtained in the previous step S2, and that user authentication has not been performed. An electronic mail automatically describing information is automatically transmitted by controlling the communication circuit 21. In step S14, the control unit 20 automatically accesses the safety confirmation site for the URL registered in advance in the memory 29, and the safety information (for example, the user's safety information created in advance or stored in the memory 29 as initial information). Address name, age, contact information, etc.) and current location information are automatically transmitted to the safety confirmation site together with information indicating that user authentication has not been performed. That is, in this embodiment, when the process proceeds from step S10 to step S14, it is considered that the user himself / herself cannot transmit the safety information due to the disaster, so the user information and its current position Information is automatically transmitted to an address registered in advance by e-mail or automatically accessed and written on a safety confirmation site. Note that both automatic transmission of electronic mail and automatic access to the safety confirmation site in step S14 may be performed, or only one of them may be performed. After the process of step S14, the process returns to the flowchart of FIG.

  As can be seen from the flowcharts of FIG. 2 and FIG. 3, when the current position when the emergency broadcast or emergency information is received is within the area where the emergency occurred, the mobile phone terminal of the present embodiment When the terminal is in a state where the terminal can be operated, the user's own safety information can be prevented at the same time by preventing congestion of the telephone contact by sending the safety information of the user himself / herself to the safety confirmation site or by e-mail. The information is surely communicated to the other party. In addition, when the mobile phone terminal of the present embodiment is in a state where the user cannot immediately operate the terminal due to an injury, for example, by automatically transmitting information on the current position together with information such as the user's name and address, You can at least tell your opponent where you are. Thereby, a user's rescue etc. become easy. In addition, as an example where the user in the stricken area does not inform himself / herself of safety, not only when the above-mentioned injury can not be contacted, but also when there is no injury etc. and it is safe and it does not contact himself / herself safely Although assumed, this embodiment can inform the other party of safety even in such a case. Furthermore, according to the mobile phone terminal of the present embodiment, even when there are safety inquiries from a plurality of destinations, it is possible to return safety information to the plurality of destinations at once by creating a single email. is there. Further, according to the present embodiment, the user does not need to remember the access method to the safety confirmation site, and can securely transmit the safety information to the safety confirmation site.

  When the processing flow proceeds from the flowchart of FIG. 2 to the processing flow outside the emergency area of FIG. 4, the control unit 20 first monitors the input from the operation unit 28 and is registered in the memory 29 as the processing of step S20. By referring to the information in the phone book, it is determined whether or not the user is trying to make a call within the emergency area (stricken area). In this way, the process of the flowchart is finished. On the other hand, when a call is to be made to the disaster area, the process proceeds to step S21.

  When the processing proceeds to step S21, the control unit 20 determines whether or not information requesting restriction on telephone access to the area is obtained from, for example, a mobile phone network when the telephone is placed, and access restriction request information is obtained. If it is determined that there is, the process proceeds to step S22. When the mobile phone network does not have a function of transmitting access restriction request information, it may be obtained from a predetermined site whether or not access restriction is made.

  When the process proceeds to step S22, the control unit 20 determines that the user is a person living in the emergency occurrence area or the like based on an input from the operation unit 28 and an address registered in the telephone book of the memory 29, for example. It is determined whether or not it is desired to acquire the safety information of a mobile phone terminal user who may be currently in the area. When it is determined that the safety information is desired to be acquired, the process proceeds to step S23.

  When the processing proceeds to step S23, the control unit 20 transmits an e-mail for confirming safety to an address previously set and registered for safety confirmation in the memory 29. In step S23, the control unit 20 automatically accesses the safety confirmation site of the URL registered in advance in the memory 29, and obtains safety information related to the other party whose safety is to be confirmed. In addition, when the other party has already received a missed call or registered a message or received an e-mail, the control unit 20 displays that the received call or message has been registered and that an e-mail has been received. It is displayed on the display of the unit 27. Note that both the transmission of the e-mail and the access to the safety confirmation site in step S23 may be performed, or only one of them may be performed. After the process of step S23, the process proceeds to step S24.

  When the process proceeds to step S24, the control unit 20 determines whether or not the other party's safety information is not obtained even after a lapse of a predetermined time, and when it is determined that the other party's safety information is not obtained, the process proceeds to step S25. Proceed with the process. In addition, you may make it notify a user that the other party's safety information is not obtained at this time.

  When the process proceeds to step S25, the control unit 20 performs the emergency broadcast or emergency information re-reception process in order to obtain the latest information, and then ends the process of this flowchart.

  As can be seen from the flowcharts of FIG. 2 and FIG. 4, when the current position when the emergency broadcast or emergency information is received is outside the area where the emergency occurred, the mobile phone terminal of the present embodiment Encourage the use of e-mails and access to safety confirmation sites instead of telephones as a means of confirmation to prevent congestion of telephone contact and make it easy to obtain the safety information of the other party in the emergency area Yes. Further, according to the present embodiment, the user does not need to remember the access method to the safety confirmation site, and can securely acquire the safety information from the safety confirmation site.

  The description of each embodiment described above is an example of the present invention.
