Description

  The present invention relates to a method for supporting search of a search target person within a certain area such as an airport, a mobile terminal device for search, a server device, a search support system, and a computer program applied to the implementation of the method.

  When boarding an air flight, the user must check the user's name, address, gender, etc. at the airport terminal building, select a seat, and carry out boarding procedures such as deposit procedures if there is baggage to be checked After checking the baggage and the body, it waits in the waiting space, and when boarding is started, it passes through the corresponding boarding gate and boards the corresponding flight.

  However, since the boarding procedure described above starts several hours before the boarding start time, after taking the boarding procedure, the user does not go to the waiting area near the boarding gate, but at the restaurant in the terminal building. Or I often spend time at other facilities such as souvenir shops. Therefore, after the boarding start time has passed, each user who has passed through the gate at the boarding gate is checked with each user who has been boarded, and the departure time is approaching. When there is a user who has been boarded and has not been confirmed to pass through the boarding gate, the user has been called by broadcast in the building.

  However, such a call has a problem that, for example, when a user is located in a place where it is difficult to hear the broadcast in the hall, the user cannot be called. Therefore, Patent Document 1 described later discloses the following method.

  That is, an RFID tag is issued to the user when the boarding procedure described above is performed, and a plurality of RFID readers are arranged at predetermined intervals in the terminal building. Each RFID reader sequentially returns information registered therein to the RFID tag. When each RFID reader receives the registration information from the RFID tag, it transmits it to the passenger boarding guidance center as position information. In the passenger boarding guidance center, boarding information related to boarding procedures is recorded for each ID related to each RFID tag, and the passenger boarding guidance center is applicable when position information of each RFID tag is transmitted from each RFID reader. It is additionally registered in the position information of the ID. In addition, when the RFID reader disposed in the vicinity of the boarding gate receives the registration information of each RFID tag, the passenger boarding guidance center records the information as boarded information in association with the corresponding ID.

  On the other hand, a boarding terminal is provided at the boarding gate described above, and when an inquiry is made from the boarding terminal to the passenger boarding guidance center, the passenger boarding guidance center has a position related to the ID for which boarding completed information is not recorded. Information and boarding information are read, and the read position information and boarding information are displayed.

As a result, since the information related to the search target user and the position thereof can be grasped from the display screen of the boarding terminal, the instruction staff can send a search instruction to the search staff by a radio device etc. Even if the user is located in a place where it is difficult to hear, the user can be searched.
