At this time, the mobile communication terminal 16 repeatedly repeats the response repetition period and the response repetition frequency until the 'RFID discovery reception acknowledgment message' is received from the short text control station 12 for the transmission of the 'RFID discovery message'. Perform the transfer.

If there is no RFID reception response in S34, the mobile communication terminal 16 continues to search for the reported RFID using the RFID reader.

Subsequently, the rescue server 11 returns the 'RFID discovery reception confirmation message' to the mobile communication terminal 16 through the short text control station 12 in response to the 'RFID discovery message' transmitted from the mobile communication terminal. Notify the operator that a 'RFID discovery message' has been received via a short text message. In addition, the rescue server 11 is mounted on its own, operating the visible, audible alarm system to ensure that appropriate measures to be made later in the search for missing persons.

Next, when the 'RFID discovery message' is received more than a certain number of times, the rescue server 11 transmits the 'search termination message' for the corresponding RFID to the mobile communication terminal 16 through the mobile communication network (S36, S37). . At this time, the 'search end message' may be delivered to all mobile communication terminals in the country. The mobile communication terminal 16 receiving the 'search end message' ends the RFID search even if the search time does not arrive. The mobile communication terminal 16 which has not received the 'search end message' continues to perform the RFID search and terminates when the search time is exceeded.

Then, the rescue server 11 transmits an emergency guide word to the mobile communication terminal 16 through the mobile communication network. For example, the emergency message could be "I found the rescue requester. Call the number below. The rescue server operator number." The mobile communication terminal 16 receives the emergency guidance text from the rescue server 11 and confirms the RFID position (S38). Meanwhile, the operator of the rescue server 11 dials the mobile communication terminal 16 that has transmitted the 'RFID discovery message' to determine the exact location of the caller, and the photograph of the missing person through the call channel with the caller's consent or unconditionally. You can also request confirmation directly by sending.

Then, when the rescue server 11 has identified the exact location of the reporter, the RFID, discovery time, exact location of the reporter, the telephone number of the reporter, the telephone of the rescue server operator found by the management server 10 of the government agency that requested the search. Automatically send 'RFID search result message' including number.

Next, when the rescue server 11 receives the 'RFID search result reception confirmation message' from the management server 10 with respect to the transmission of the 'RFID search result message', the rescue server 11 deletes the data in the rescue server 11 for the corresponding RFID. And transmits the 'RFID search result acknowledgment message' to the short text control station 12. The short character control station 12 transmits a 'RFID search result notification message' to the operator of the management server 10 which is already registered, and notifies that the RFID search result has been delivered to the server.
