ATIS Completes Four Specifications for New Version of WEA
Thursday, May 23, 2019 | Comments

The Alliance for Telecommunications Industry Solutions (ATIS) announced the completion of four key deliverables in support of setting version 3.0 of the Wireless Emergency Alerts (WEA) system into action by Nov. 30.

Among other enhancements, WEA will deliver potentially life-saving messages in a more precise geographic range. The goal is to target at-risk populations while minimizing disruption to others outside of the target alert area. WEA 3.0 also requires preservation of alerts for at least 24 hours after the message is received on the mobile device or until deleted by the user.

While three of the new WEA deliverables are updates to existing WEA 2.0 standards, the geo-fencing standard, “WEA 3.0: Device-Based Geo-Fencing,” is a new specification. It defines how geo-targeted WEA alert messages are delivered based upon the alert-originator-provided circle or polygon coverage of the target area.

ATIS also updated existing WEA specifications to address defining a set of requirements for the behavior of the mobile devices when a WEA alert message is received, defining the interface between the federal alert gateway and the commercial mobile service provider gateway for WEA alerts, and providing a public warning system specification that describes the use of the evolved packet system public warning system for the delivery of WEA 3.0 messages.

The ATIS standards making these new abilities possible are for use by commercial mobile service providers, infrastructure vendors, device operating system (OS) providers, OEMs and chipset manufacturers in developing the WEA 3.0 system. They are part of a continuum of ATIS standards that created the WEA system and are advancing its effectiveness.

“These standards were delivered on time to meet deadline-driven FCC requirements,” said ATIS President and CEO Susan Miller. “As with many of the other WEA standards, ATIS members have introduced the necessary changes to the relevant 3GPP specifications for global adoption.”

Operational since 2012, WEA provides test-like alerts using the cell broadcast system across three categories: alerts issued by the president; alerts involving imminent threats to safety or life; and Amber, Silver and Blue.
