For this reason, even when the mobile terminal does not support CBS or when the mobile terminal is not in a standby state, emergency information can be promptly and reliably notified to the user of the mobile terminal in the house R. In the present embodiment, since the femto base station 100 notifies the emergency information using the display 211 or the like immediately before distributing the emergency information to the mobile terminal 200, the emergency information is promptly transmitted to the user 200a in the house R. Can be notified.

  In this embodiment, the femto base station 100 controls the gas stove 40 installed in the house R based on the content of the acquired emergency information. For this reason, for example, even when an earthquake occurs, the user 200a in the house R performs actions for preventing secondary disasters such as turning off the gas stove 40 before a large shake reaches the house R. It is not necessary, and as soon as emergency information is recognized, it is possible to take an escape action immediately.

  In the present embodiment, the femto base station 100 can also control an external device such as the gas stove 40 after transmitting a control confirmation message to the mobile terminal 200 and obtaining permission from the user 200a. For this reason, it is possible to reliably control only an external device that needs to be controlled when a disaster occurs by a simple operation using the mobile terminal 200 by the user 200a.

  In the present embodiment, a reception confirmation message for confirming whether or not the user 200a has received the emergency information is transmitted from the femto base station 100 to the mobile terminal 200. The femto base station 100 relays a response indicating that the user 200a has received the emergency information to the management server 30, and the management server 30 registers the identification number (telephone number) of the mobile terminal 200.

  For this reason, it is possible to manage information on users who are in the communication area formed by the femto base station 100 when a disaster occurs and who have received emergency information. Such information can be used for rescue support when the house R collapses or for safety confirmation by concerned parties (such as family members) who are concerned about the victims.
