Abstract

A geocast alerting system employs wireless geocast transmissions to deliver customized alerting messages to particular geographic areas. Geocast alerting regions and sub-regions can be defined within the system. Upon notice of the occurrence of an emergent situation, one or more geographic areas that may potentially be affected by the emergent situation are determined. The potentially effected geographic regions are compared with geocast alerting regions and sub-regions corresponding to particular geographic areas. Target alerting regions that should receive alerting messages are identified based on the comparison. The content of alerting messages can be tailored for each target alerting region. The content of alerting messages can contain distinct portions of content, each portion tailored based upon one or more conditions related to communications devices within the target alerting region.

Claims

1. A method comprising:

receiving a signal indicative of an alerting message, the signal comprising;

an indication of a target distribution region for the signal; and

an indication of alerting message content;

comparing a location at which the signal was received with the target distribution region;

when the location at which the signal was received is at least one of the same as, a part of, or overlaps with the target distribution region, rendering the alerting message content;

determining whether the signal has been received at least a predetermined number of times; and

when it is determined that the signal has been received at least the predetermined number of times, determining whether the signal was sent from a location closer than a minimum distance from the location at which the signal was received.

2. The method of claim 1, wherein the signal further comprises a plurality of indications of alerting message content portions, at least one of the content portions tailored based upon a context condition.

3. The method of claim 2, further comprising:

determining whether the context condition applies; and

when the context condition applies, rendering the at least one of the content portions tailored based upon the context condition.

4. The method of claim 1, wherein the content is determined at a time when the signal is sent.

5. The method of claim 1, wherein the content is rendered at least one of visually, aurally, or mechanically.

6. The method of claim 1, further comprising:

when the location at which the signal was received is at least one of the same as, a part of, or overlaps with the target distribution region, rendering an indication of a sender location,

wherein the signal further comprises the indication of a sender location.

7. The method of claim 1, wherein the alerting message comprises a response to a geographic query.

8. The method of claim 1, further comprising:

when it is determined that the signal has been received at least the predetermined number of times and it is determined that the signal was not sent from a location closer than the minimum distance from the location at which the signal was received, retransmitting the signal.

9. A computer-readable storage medium that is not a propagating signal, the computer-readable storage medium having instructions stored thereon that when executed by a processor cause the processor to effectuate operations comprising:

receiving a signal indicative of an alerting message, the signal comprising;

an indication of a target distribution region for the signal; and

an indication of alerting message content;

comparing a location at which the signal was received with the target distribution region;

when the location at which the signal was received is at least one of the same as, a part of, or overlaps with the target distribution region, rendering the alerting message content;

determining whether the signal has been received at least a predetermined number of times; and

when it is determined that the signal has been received at least the predetermined number of times, determining whether the signal was sent from a location closer than a minimum distance from the location at which the signal was received.

10. The computer-readable storage medium of claim 9, the method further comprising:

when it is determined that the signal has been received at least the predetermined number of times and it is determined that the signal was not sent from a location closer than the minimum distance from the location at which the signal was received, retransmitting the signal.
