Abstract

A disaster response system receives location data and status data from participating devices in an area affected by a disaster. The disaster response system provides data to client devices outside the affected area. The data indicate statuses of people within the affected area. Disaster response system also instructs routers to perform actions to adjust bandwidth available for a particular use during and after the disaster.

send location data to a coordination data center automatically in response to receiving the disaster alert message, the location data indicating a geographical location of the participating device;

in response to receiving the disaster alert message, use the map data to determine an escape route for a user of the participating device;

send new location data to the coordination data center in response to receiving a post-disaster message after a disaster has stopped actively affecting an area, the new location data indicating a new geographical location of the participating device; and

send status data to the coordination data center in response to the post-disaster message, the status data indicating whether the user of the participating device needs emergency assistance.

7. A method comprising:

sending map data to a participating device before the participating device receives a disaster alert message, the participating device configured to store the map data on the participating device before the participating device receives the disaster alert message;

sending the disaster alert message to the participating device when the participating device is in an area affected by a disaster, the participating device configured to use the map data to determine an escape route for a user of the participating device in response to receiving the disaster alert message;

receiving a first location message from the participating device after sending the disaster alert message, the first location message indicating a location of the participating device;

sending a post-disaster message to the participating device after sending the disaster alert message to the participating device;

receiving new location data and status data from the participating device after sending the post-disaster message, the new location data indicating a new location of the participating device, the status data indicating whether the user of the participating device needs emergency assistance; and

providing an interface to a user outside the area affected by the disaster, the interface containing data indicating whether the user of the participating device needs emergency assistance.

8. The method of claim 7, further comprising:

before sending the disaster alert message to the participating device, identifying the participating device as being in the area affected by the disaster.

9. The method of claim 7, further comprising sending a message to a router, the message instructing the router to perform actions that adjust bandwidth available for a particular use.

10. The method of claim 9, wherein the actions that adjust bandwidth available for the particular use include dropping packets that have payloads belonging to non-essential protocols and also have either source addresses or destination addresses in sets of addresses associated with the area.

11. The method of claim 10, the non-essential protocols including protocols that carry voice data.

12. A coordination data center comprising a processing system that comprises one or more processing units that execute computer-readable instructions that cause the coordination data center to:

send map data to a participating device before the participating device receives a disaster alert message, the participating device configured to store the map data on the participating device before the participating device receives the disaster alert message;
