GEO-TARGETED ALERTING BASED ON POWER CONTOUR
First Claim
1. Geotargeting an alert based on power contour of relevant cell sites, comprising:
- identifying a targeted area for a given alert;
identifying all included cell sites within said targeted area;
identifying all outlying cell sites outside said targeted area but having an RF power contour covering a service area within said targeted area; and
broadcasting said given alert to all included cell sites and outlying cell sites to alert subscriber devices being serviced by said included cell sites and outlying cell sites.

Abstract
Enhanced cell site database information and a spatial geotargeting method that considers radio frequency power contours emitted by cell sites, for the improved accuracy of geotargeted alerting. A geotargeted alert is broadcast to all cell sites with a RF power contour that overlaps an alert area defined for the alert. Targeted cell sites receive the alert and broadcast the alert to subscriber devices located in their coverage area. An RF propagation model computes an RF power contour for a given cell site based on cell site attribute data obtained from a commercial mobile service provider. Cell site attribute data and cell site power contour data is stored in a GIS relational database during system provisioning. When an alert is received, a mobile alerting system performs a spatial query on the relational database to determine which cell sites have a power contour that overlaps an alert area defined for the alert.
