Abstract

A method and wireless device augment and manage, respectively, emergency alert messages with additional emergency information. An emergency alert message is determined to have been sent (404) to one or more wireless devices (102) in a given area. The emergency alert message is analyzed (406) to determine a type of emergency associated with the emergency alert message. Optionally, a current location of at least one wireless device (102) within the given area is determined. A message is generated (412), based at least in part on the type of emergency and logistics of the given area, including additional emergency information for augmenting the emergency alert message. The message that has been generated is transmitted to the at least one wireless device (102). This message is, optionally, adjusted based on the location of the device and the logistics of the given area.

Claims

1. A method for augmenting emergency alert messages with additional emergency information, the method comprising:

determining, by an augmenting notification system, that an emergency alert message has been sent to at least one wireless device in a given area;

analyzing, by the augmenting notification system, the emergency alert message to determine a type of emergency associated with the emergency alert message;

generating, by the augmenting notification system, an augmented emergency alert message, based at least in part on the type of emergency and logistics of the given area, comprising the additional emergency information including directional prompts indicating a direction to follow towards an exit;

transmitting, by the augmenting notification system, the message that has been generated to the at least one wireless device;

instructing, by the augmenting notification system, the at least one wireless device to monitor transmissions from at least one emergency beacon generating device by a set of signals that provide a set of varying feedback to the at least one wireless device based on a current location of the at least one wireless device;

wherein the set of varying feedback comprises at least one of;

flashing lights at the at least one wireless device;

changing text at the at least one wireless device;

audio prompts at the at least one wireless device; and

tactile prompts at the at least one wireless device.

2. The method of claim 1, further comprising:

determining, by the augmenting notification system, a current location of the at least one wireless device within the given area.

3. The method of claim 2, wherein determining a current location of the at least one wireless device within a given area further comprises at least one of:

determining, by the augmenting notification system, location coordinates associated with the at least one wireless device;

determining, by the augmenting notification system, a location based on a monitored signal strength of a signal associated with the at least one wireless device; and

receiving, by the augmenting notification system, positioning information from the at least one wireless device.

4. The method of claim 1, wherein the determining that an emergency alert message has been sent to the at least one wireless device further comprises at least one of:

detecting, by the augmenting notification system, an emergency notification signal from an emergency notification device; and

determining, by the augmenting notification system, that an emergency beacon has been generated at an emergency beacon generating device.

5. The method of claim 1, wherein generating a message further comprises:

determining a route to the exit.

6. The method of claim 5, wherein the route is one of:

a pre-programmed route; and

a route determined based on a current location of the at least one wireless device.

7. A method, with a wireless device, for managing augmented emergency alert messages, the method comprising:

receiving, by the wireless device, an emergency alert message from at least one emergency notification device;

receiving, by the wireless device, an augmenting message from at least one emergency notification augmenting device, wherein the augmenting message comprises additional emergency information associated with the emergency alert message;

analyzing, by the wireless device, the augmenting message; and

providing directional prompts, by the wireless device, indicating a direction to follow towards an exit based on the additional emergency information;

wherein providing the directional prompts indicating the direction to follow towards the exit based on the additional emergency information, further comprises;

determining a current location of the wireless device;

comparing the current location of the wireless device with directional information included within the additional emergency information; and

providing the wireless device with the directional prompts based on the comparing.

8. The method of claim 7, further comprising:

establishing, by the wireless device, a short range radio frequency communication link with the at least one emergency notification augmenting device.

9. The method of claim 7, wherein the additional emergency information comprises directional information associated with an exit, wherein the directional information is used by the wireless device for providing the directional prompts indicating the direction to follow towards the exit.

10. The method of claim 7, wherein the directional prompts include at least one of:

audio prompts;

visual prompts; and

tactile prompts.

11. The method of claim 7, wherein the additional emergency information includes instructions to monitor transmissions from at least one emergency beacon generating device, and wherein providing the directional prompts indicating the direction to follow towards the exit based on the additional emergency information further comprises:

monitoring, by the wireless device, the at least one emergency beacon to determine if a signal strength associated with the at least one emergency beacon is one of decreasing and increasing,

wherein if the signal strength associated with the at least one emergency beacon is decreasing,

prompting, by the wireless device, to change a current direction of movement; and

wherein if the signal strength associated with the at least one emergency beacon is increasing,

prompting, by the wireless device, to continue heading in a current direction.

12. A wireless device for managing augmented emergency alert messages, the wireless device comprising:

a memory;

a processor communicatively coupled to the memory;

a user interface communicatively coupled to the memory and the processor; and

an emergency alert manager communicatively coupled to the memory, the processor, and the user interface, wherein the emergency alert manager is configured to;

receive an emergency alert message from at least one emergency notification device;

receive an augmenting message from at least one emergency notification augmenting device, wherein the augmenting message comprises additional emergency information associated with the emergency alert message;

analyze the augmenting message; and

provide directional prompts, via the user interface, indicating a direction to follow towards an exit based on the additional emergency information;

wherein the emergency alert manager is further configured to provide the directional prompts indicating the direction to follow towards the exit based on the additional emergency information by;

determining a current location of the wireless device;

comparing the current location of the wireless device with directional information included within the additional emergency information; and

providing the directional prompts based on the comparing.

13. The wireless device of claim 12, wherein the emergency alert manager is further configured to:

establish a short range radio frequency communication link with the at least one emergency notification augmenting device.

14. The wireless device of claim 12, wherein the additional emergency information comprises directional information associated with an exit, wherein the directional information is used by the emergency alert manager for providing the directional prompts indicating the direction to follow towards the exit.

15. The wireless device of claim 12, wherein the directional prompts include at least one of:

audio prompts;

visual prompts; and

tactile prompts.

16. The wireless device of claim 12, wherein the additional emergency information includes instructions to monitor transmissions from at least one emergency beacon generating device, and wherein the emergency alert manager is further configured to provide the directional prompts indicating the direction to follow towards the exit based on the additional emergency information by:
