Method for geo-targeting wireless emergency alerts
First Claim
1. A method comprising:
- receiving an indication of an affected geographic area;
identifying cell sites relevant to the affected geographic area;
determining emergency alert broadcast capabilities of each identified cell site, wherein emergency alert broadcast capabilities of each identified cell site comprise a capability of each identified cell site to handle wireless emergency alerts;
providing an indication of emergency alert broadcast capabilities of the identified cell sites; and
mapping a relationship between the affected geographic area and at least one secondary geographic area that is at least partially within the affected geographic area, wherein the emergency alert broadcast capabilities for the cell sites in the affected geographic area are determined based on the emergency alert broadcast capabilities of the at least one secondary geographic area, wherein a same base station serves the affected geographic area and the at least one secondary geographic area.

Abstract
Geo-targeting may be used in combination with wireless alert capabilities to provide alerts to a more granulated geographical area. Disclosed herein is a system and method for performing geo-targeting for various alert areas such that emergency messages may be delivered to mobile and static devices of different types in a localized area. In an example embodiment, geo-targeting supports the delivery area for wireless emergency alerts by identifying the cell sites that are in a specified geographic area that have technology capable of delivering wireless emergency alerts. The components of the telecommunications system that support a wireless emergency alert system may be identified and mapped to any geographical area. The method and system of geo-target mapping may provide an efficient and more robust way of determining the telecommunication components to be employed for broadcasting emergency alerts.

1. A method comprising:
-
receiving an indication of an affected geographic area; identifying cell sites relevant to the affected geographic area; determining emergency alert broadcast capabilities of each identified cell site, wherein emergency alert broadcast capabilities of each identified cell site comprise a capability of each identified cell site to handle wireless emergency alerts; providing an indication of emergency alert broadcast capabilities of the identified cell sites; and mapping a relationship between the affected geographic area and at least one secondary geographic area that is at least partially within the affected geographic area, wherein the emergency alert broadcast capabilities for the cell sites in the affected geographic area are determined based on the emergency alert broadcast capabilities of the at least one secondary geographic area, wherein a same base station serves the affected geographic area and the at least one secondary geographic area. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A method comprising:
-
determining emergency alert broadcast capabilities of a cell site, wherein emergency alert broadcast capabilities of a cell site comprise a capability of a cell site to handle wireless emergency alerts; compiling indications of the emergency alert broadcast capabilities of the cell site, wherein the cell site is associated with a cell site identity (ID); and mapping the cell site identity (ID) to a geographic area, wherein the geographic area is a first geographic area that is a subset of a second geographic area, and the second geographic area is mapped to the first geographic area such that the cell site identity (ID) is associated with both the first and second geographic areas, wherein a same base station serves the first geographic area and the second geographic area. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. An emergency alert system comprising:
-
a processor configured to determine emergency alert broadcast capabilities of the cell site, wherein emergency alert broadcast capabilities of the cell site comprise a capability of the cell site to handle wireless emergency alerts; and a geo-target mapping module configured to map an identity of the cell site to a geographic area, wherein the cell site identity is provided upon a request of the broadcast capabilities within the geographic area, wherein the geographic area is a first geographic area that is a subset of a second geographic area, and the cell site identity is provided for the second geographic area based on the cell site mapped to the first geographic area, wherein a same base station serves the first geographic area and the second geographic area. - View Dependent Claims (17, 18, 19)
