Description

  The present invention relates to a radio base station, a mobile communication system, a mobile terminal, a device control method, and a terminal user management method using emergency information such as an earthquake early warning.

  In October 2007, the Japan Meteorological Agency began distributing emergency earthquake bulletins for the general public (such as television and radio). Along with such movements, distribution of emergency earthquake bulletins to mobile terminals has been studied using mobile communication systems. In addition to emergency earthquake warnings, we want to deliver emergency information (for example, evacuation advisories) that local governments need to notify mobile terminals as soon as possible when disasters such as floods occur. There is also a request.

  As a method for broadcasting such emergency information to mobile terminals, for example, Cell Broadcast Service (CBS) and Multimedia Broadcast Multicast Service (MBMS) defined in 3GPP are known (Non-patent Document 1 and Non-Patent Document 1). Patent Document 2).

  In step S200, the femto base station 100 relays a response indicating that the user has received the emergency information to the management server 30. Specifically, the femto base station 100 transmits the reception registration collected in step S190 to the management server 30 as a registration notification.

  In step S210, the management server 30 registers the mobile terminal based on the content of the registration notification received from the femto base station 100.

  Specifically, as illustrated in FIG. 11, the management server 30 registers a radio base station and a mobile terminal located in the communication area of the radio base station in association with each other.

(6) Operation / Effect According to the mobile communication system 1, the femto base station 100 is a small radio base station installed in the house R, and based on the contents of the emergency information acquired by the emergency information acquisition unit 103, Emergency information can be notified in the house R. 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.

(7) Other Embodiments As described above, the content of the present invention has been disclosed through one embodiment of the present invention. However, it is understood that the description and drawings constituting a part of this disclosure limit the present invention. should not do. From this disclosure, various alternative embodiments will be apparent to those skilled in the art.

  For example, in the above-described embodiment of the present invention, the mobile communication system 1 broadcasts emergency information to the femto base station 100 and the mobile terminal 200 based on CBS, but broadcasts emergency information to the mobile terminal. The method to do is not limited to CBS, but may be MBMS or the like. In the above-described embodiment, the femto base station 100 is connected to the core network 25 via the RNC 20, but may be directly connected to the core network 25. In this case, the femto base station 100 may acquire a message such as System Information Update Request via the core network 25.

  In the above-described embodiment, the femto base station 100 (the output control unit 109) broadcasts emergency information using the display 113. However, the femto base station 100 performs emergency information according to the type and content of the acquired emergency information. The notification method may be different. For example, in the case of an emergency earthquake warning, the acoustic signal may be changed according to the time required until a large shake reaches the area of the house R and the assumed seismic intensity. Further, the femto base station 100 may display emergency information via a screen of an external device (for example, a television, a landline phone, or a personal computer) connected to the home network 45 without using the speaker 111 or the display 113.
