And a short-range wireless communication module that performs short-range wireless communication such as Bluetooth (registered trademark) or UWB (Ultra Wide Band) with at least the mobile phone terminal 2. .

  The mobile phone terminal 2 has a function of acquiring current position information and current time information from at least one of the GPS satellite 10 and the base station 11 in addition to the functions of a general mobile phone terminal, for example, Bluetooth or UWB A near field wireless communication function such as a function, a function for confirming that the near field wireless communication module of the accessory terminal 3 is present in the communicable area in the near field wireless communication, and a predetermined management server 13 or It has a function of making an emergency notification by automatically connecting to a predetermined manager communication terminal (not shown) or a management center such as a security company or police. Note that the current time information may be obtained by a clock function in the mobile phone terminal 2.

  Then, the cellular phone terminal 2 of the present embodiment has the above-mentioned short distance because, for example, kidnapping or the like occurs and the child 1 releases the accessory terminal 3 from his body (intentionally) and is moved by, for example, a kidnapper The wireless communication module is out of the communicable area (that is, the distance between the short-distance communication module and the terminal 2 is more than the communicable distance for short-distance wireless communication), and as a result, the communication is performed at the confirmation at the predetermined time. When it is detected that an emergency has occurred, it is determined that an emergency such as kidnapping has occurred, and the current position information and the current time are obtained from the GPS satellite 10 and the base station 11 at that time and every certain time thereafter. The information is acquired, and the acquired current position information and current time information together with identification information (for example, telephone number and terminal ID) of the own terminal, the management server 13 and the predetermined management To send communication terminal or sequentially to the management center, such as security companies and police.

  That is, when an emergency such as kidnapping occurs, the mobile phone terminal 2 according to the present embodiment performs kidnapping or the like to the management server 13, a predetermined administrator communication terminal, or a management center such as a security company or police. An emergency notification of occurrence and subsequent current position information and current time information is made.

  Examples of the manager communication terminal include a mobile phone terminal such as a parent of a child who owns the mobile phone terminal 2 and a personal computer. In addition, a certain time for the mobile phone terminal 2 to confirm the presence of the accessory terminal 3 and a certain time for the mobile phone terminal 2 to acquire and transmit current position information and current time information from the GPS satellite 10 or the base station 11. The time is, for example, a different time.

  The predetermined management server 13 has a function of connecting to a mobile phone network via the network 12 such as the Internet or a dedicated line, and the current time from the mobile phone terminal 2 through the mobile phone network and the Internet or a dedicated line at a predetermined time.

  The search support image 14 is displayed using position information browsing support software such as so-called GIS (geographic management system) software in an administrator communication terminal, a security company, or a management center such as the police. Further, the circles a to g in the search support image 14 of FIG. 1 represent each position obtained based on the current position information and the current time information sent from the mobile phone terminal 2 at regular intervals. The arrows connecting the circles a to g represent the movement route.

[Outline of indirect emergency notification system using other person's terminal]
By the way, when the kidnapped child is confined indoors or underground where radio waves from the GPS satellite or the base station do not reach, for example, the mobile phone terminal 2 of the present embodiment Information cannot be acquired, and the current position information and current time information cannot be transmitted to the management server 13 or the administrator communication terminal.

  When the radio wave does not reach from the GPS satellite or the base station as described above, the mobile phone terminal 2 of this embodiment uses the short-range wireless communication function as shown in FIG. A predetermined message for requesting emergency notification to the terminal 32 is transmitted at regular intervals.

  The mobile phone terminal 32 that has received the predetermined message for the emergency notification request performs a display for requesting permission for the emergency notification request to the other person 31 (the owner 31 of the terminal 32), and the like. When the permission is obtained from the owner 31, current position information (current position information of the terminal 31) and current time information are acquired from at least one of the GPS satellite 10 and the base station 15. The time information, together with the identification information of the mobile phone terminal 2 that has made the emergency notification request and the identification information of its own terminal, is automatically connected to a predetermined management server 13 or a management center such as a security company or police and notified.

  In addition, the mobile phone terminal 32 may transmit information indicating support for the emergency notification from the mobile phone terminal 2 together with the information. Further, the current time information may be acquired by a clock function in the mobile phone terminal 32. In addition, the mobile phone terminal 32 does not ask the owner 31 for permission for the emergency notification request, and backs up the acquisition process of the current position information, the current time information, etc. and the process of notifying the management server 13 of the information. You can do this automatically on the ground.

  That is, according to the system of the present embodiment, when a child is confined in a place where radio waves of GPS satellites and base stations do not reach, the mobile phone terminal 32 existing in the vicinity of the mobile phone terminal 2 Position information obtained on behalf of a satellite or base station, that is, information at a position very close to the position where the child is confined, is indirectly transmitted to the management server 13 or a management center such as a security company or police through the mobile phone terminal 32. Can be notified (substitute notification).

  The terminal that receives the emergency notification request message from the mobile phone terminal 2 is not limited to one mobile phone terminal 32 of the other person (emergency notification supporter) 31 but may be a plurality of other mobile phone terminals. Alternatively, for example, it may be a terminal dedicated to receiving an emergency notification request message attached to a predetermined facility such as a utility pole, an indoor outlet, an indoor modular terminal, or an indoor light connection terminal. When the dedicated terminal that receives the emergency notification request message receives the emergency notification request message by the short-range wireless communication from the mobile phone terminal 2, the position information stored in advance (the current position information of the dedicated terminal) and the built-in clock Is automatically notified to the predetermined management server 13 or a management center such as a security company or police together with the identification information of the mobile phone terminal 2 that has made the emergency notification request.

  In the present embodiment, the emergency notification request message transmitted by the mobile phone terminal 2 of the child 1 by short-range wireless communication is transmitted without specifying the transmission destination, so that the emergency notification request message is the mobile phone of the kidnapper. There is also a risk of being received by the terminal. At this time, if the mobile phone terminal of the kidnapper displays, for example, a request for permission of the emergency notification request as described above, an emergency notification request message is transmitted from the mobile phone terminal 2 of the child 1. The kidnapper will know that you are.

  For this reason, the mobile phone terminal 2 according to the present embodiment is, for example, the presence of other mobile phone terminals in the vicinity by short-range wireless communication immediately after the accessory terminal 3 is removed from the communicable area (that is, immediately after kidnapping). Do not send the above emergency notification request message to mobile phone terminals that are always in the vicinity immediately after the kidnapping (that is, terminals that are likely to be kidnapper terminals) While the telephone terminal exists in the vicinity, a function of not performing the transmission process of the emergency notification request message may be provided.

  In addition, the mobile phone terminal 2 of the present embodiment acquires the identification information of the mobile phone terminal that is highly likely to be the kidnapper's terminal in the background by the short-range wireless communication, and the identification information is managed by the management server 13. And a function of automatically notifying a management center such as a security company or police. Furthermore, since there may be accomplices in addition to the kidnapper, the mobile phone terminal 2 of the present embodiment is located in the vicinity together with the mobile phone terminal that is likely to be the kidnapper's terminal. Similarly to the above, the mobile phone terminal (that is, the terminal that is likely to be the accomplice's terminal) may not be sent the emergency notification request message, or may be (Terminal) identification information may be acquired in the background and a function of automatically notifying the identification information to the management server 13 or the like may be provided.

[Outline of preventing false notifications]
The emergency notification system according to the present embodiment is configured to transmit the current position information and the current time information to the management server 13 and the like when the accessory terminal 3 is out of the short-range wireless communication area of the mobile phone terminal 2. The accessory terminal 3 may leave the mobile phone terminal 2 in a situation where an emergency notification is not intended. For example, when the accessory terminal 3 is mounted on a shoe, the accessory terminal 3 is separated from the mobile phone terminal 2 when a child takes off his shoes at a school or home entrance and enters a classroom or room. It will be. In such a case, the current position information and the current time information are erroneously transmitted to the management server 13 or the like, even though the emergency notification is not intended.

  In order to prevent such a false notification in a situation where an emergency notification is not intended, the mobile phone terminal 2 of the present embodiment is safe for a child to act on a daily basis, such as in a school or at home. Location information of an area (denoted as daily activity area) can be registered in advance, and the accessory terminal 3 is out of the short-distance wireless communication area of the mobile phone terminal 2 within the daily activity area. Even so, it has a function of not acquiring the current position information and current time information and transmitting them to the management server 13 or the like.

  In the above example, the case where the daily action area is registered in the mobile phone terminal 2 has been described. However, the daily action area may be registered on the management server 13 or the administrator communication terminal side, for example. In this case, when the accessory terminal 3 is out of the short-range wireless communication area of the mobile phone terminal 2, the mobile phone terminal 2 acquires the current position information and current time information and transmits the information as described above. However, the management server 13 or the administrator communication terminal side that has received the information determines whether or not the mobile phone terminal 2 is present in the daily action area from the current position information. Information from the mobile phone terminal 2 is not handled as emergency notification information.

  In addition, the mobile phone terminal 2 of the present embodiment stops the emergency notification function not only by automatic control based on the daily activity area but also by the user (child 1) himself or by remote operation from the administrator communication terminal. It is also possible.

[Outline of system control according to battery level of accessory terminal]
In the emergency notification system of this embodiment, since the accessory terminal 3 and the mobile phone terminal 2 are configured to perform short-range wireless communication, the accessory terminal 3 runs out of battery power and the accessory terminal 3 becomes inoperable. If the mobile phone terminal 2 cannot communicate with the accessory terminal 3, the mobile phone terminal 2 may erroneously determine that the accessory terminal 3 is out of the short-range wireless communicable area.

  For this reason, the mobile phone terminal 2 of the present embodiment always obtains information on the remaining battery level from the accessory terminal 3 and displays, for example, when the remaining battery level of the accessory terminal 3 is low. As a result, the user (in this case, the child 1) is notified, the administrator communication terminal is notified, and it is further ensured that the battery level of the accessory terminal 3 is lower than that required for short-range wireless communication. In some cases, a function for stopping the function for making the emergency notification is provided.
