CAMPUS ALERTING VIA WIRELESS GEOCAST

摘要

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.

1. An apparatus comprising:
a processor; and memory coupled to the processor, the memory comprising executable instructions that when executed by the processor cause processor to effectuate operations comprising:
identifying a target geographic region for receipt of an alerting message pertaining to an emergent situation; andproviding the alerting message, the alerting message comprising an indication of the target geographic region and an indication of the emergent situation, wherein:
the alerting message is renderable by a recipient device of the alerting message based on a determination by the recipient device that a location at which the alerting message is received is within the target geographic region; andthe alerting message is retransmittable by the recipient device based on a determination by the recipient device that the alerting message has been received at least a predetermined number of times.
