Members 60-1 and 60-2. Hereinafter, the home base stations 10-1 and 10-2 may be collectively referred to as the home base station 10. In addition, the communication terminals 40-0, 40-1, and 40-2 may be collectively referred to as the communication terminal 40. Further, the business operators 60-1 and 60-2 may be collectively referred to as the business operators 60.

The home base station 10 is a small base station device (Home eNodeB [indoor base station device], micro cell eNodeB) that transmits and receives data wirelessly with a mobile station device (User Equipment) such as the communication terminal 40 or the unmanned aircraft 20. [Microcell base station apparatus], pico cell eNodeB [picocell base station apparatus], and femto cell eNodeB [femtocell base station apparatus]). The radius of a cell (range in which radio waves reach) that the home base station 10 provides services is, for example, a relatively narrow range of several meters to several tens of meters. That is, the home base station 10 is a base station device that has a narrow communication range with the mobile station device (typically, a radius of several meters to several tens of meters). The home base station 10 is installed, for example, in each residential space of an apartment. The home base stations 10-1 and 10-2 are connected to be communicable with each other via a network. In the present embodiment, the number of home base stations 10 is not limited to the two illustrated, and may be one or more than two.

The unmanned aerial vehicle 20 is a drone, for example, and is a small aircraft that can fly unattended by remote control or automatic control. The unmanned aerial vehicle 20 is a mobile station device that wirelessly transmits and receives data to and from the home base station 10. In the present embodiment, the number of unmanned aerial vehicles 20 is not limited to the illustrated one, and may be more than one.

The communication terminal 40 is a mobile station device that transmits and receives data to and from the home base station 10 wirelessly. The communication terminal 40 is, for example, a mobile phone, a smart phone, or a personal digital assistant (Personal Digital Assistant, PDA). In the present embodiment, the number of communication terminals 40 is not limited to the illustrated three, and may be one, two, or more than three.

The drone control system 50 is a system that manages the operation of the unmanned aircraft 20, and includes, for example, one or a plurality of server devices. The business operator 60 is an information processing apparatus such as a computer managed by a business operator (for example, a delivery company) that owns the unmanned aircraft 20. In the present embodiment, the number of business operators 60 is not limited to the two illustrated, and may be one or more than two.

Then, the outline | summary of the emergency alert notification system 1 is demonstrated.
The unmanned aerial vehicle 20 searches the surroundings to find a connectable home base station 10, and flies while connecting to the found home base station 10. At this time, the unmanned aircraft 20 transmits emergency information to the connected home base station 10 when a failure occurs. The emergency information is data indicating that a failure has occurred in the unmanned aerial vehicle 20 (emergency of the unmanned aircraft 20). The drone ID, which is the identification information of the unmanned aircraft 20, the failure level, the position information, and the unmanned aircraft 20 And at least a part of the open / close state of the parachute included in the unmanned aerial vehicle 20. The failure level indicates the degree of failure, and the higher the level, the more likely it will crash. The position information is GPS coordinates acquired by GPS (Global Positioning System), and includes latitude, longitude, and altitude.

When the home base station 10 determines that the unmanned aircraft 20 is in an emergency, the home base station 10 outputs an emergency warning based on the emergency information. For example, the home base station 10 determines that the unmanned aircraft 20 has become an emergency when it receives emergency information from the unmanned aircraft 20 or when communication with the unmanned aircraft 20 is suddenly interrupted. When the home base station 10 receives the emergency information from the unmanned aircraft 20, the home base station 10 acquires the aircraft information of the unmanned aircraft 20 from the drone control system 50 based on the received emergency information. The airframe information is data related to the unmanned aircraft 20 and includes, for example, the size, color, and photograph of the airframe. Specifically, the home base station 10 transmits an aircraft information request including the drone ID included in the emergency information to the drone control system 50.

Then, the drone control system 50 returns an aircraft information response including the acquired aircraft information to the home base station 10.

When the home base station 10 receives the aircraft information response, the home base station 10 transmits an emergency alert to at least a part of the communication terminals 40 in the cell provided by the home base station 10 (may be broadcast or multicast). For emergency alerts, mechanisms such as PWS (Public Warning System), ETWS (Earthquake Tsunami Warning System), CMAS (Commercial Mobile Alert Service), etc., system information (System 20) Is information based on emergency information. The emergency alert may include the drone ID of the unmanned aircraft 20, position information, airframe information, an estimated required time to fall, and a failure level. The estimated required time to fall is the required time to fall predicted based on the altitude of the unmanned aircraft 20 included in the emergency information, the acceleration of the unmanned aircraft 20 and the open / close state of the parachute.

When receiving the emergency alert, the communication terminal 40 notifies the user that the unmanned aircraft 20 has been dropped (the unmanned aircraft 20 is in an emergency state). For example, the communication terminal 40 notifies the user that the unmanned aircraft 20 has fallen by outputting a warning sound different from the earthquake tsunami warning. The warning sound may be a melody, a volume, a tone, or a length according to the failure level of the unmanned aircraft 20. Further, the communication terminal 40 notifies the user that the unmanned aircraft 20 has been dropped by displaying the received emergency alert. At this time, the communication terminal 40 may display the position information of the unmanned aircraft 20 included in the emergency alert on the map. Further, the communication terminal 40 may display a nearby evacuation place on a map in order to evacuate the user to a safe place.
