scope:

One of the objectives of this WEA specification is to define a set of requirements for the behavior of the mobile devices whenever a WEA alert message is received. This specification defines a set of requirements for Global System for Mobile Communications (GSM), Universal Mobile Telecommunication System (UMTS), Long-Term Evolution (LTE), and 5G based mobile devices. Implementation of the requirements contained within this specification is mobile device manufacturer dependent.

Even though the scope of WEA includes paging systems, the behavior of paging devices for WEA alert messages is not contained within this specification.

More information about previous versions of WEA can be found in the WEA 3.0 Service Description [Ref 100].

Purpose

The purpose of this specification is to define the WEA 3.0 set of requirements for GSM, UMTS, LTE, and 5G based mobile devices behavior. This WEA 3.0 mobile device behavior specification is based upon the WEA enhancements identified in the January 2018 FCC Second Report & Order and Second Order on Reconsideration, FCC 18-4 [Ref 14].

Any assumptions, requirements, and principles from ATIS-0700036, Enhanced Mobile Device Behavior Specification which are applicable to WEA 3.0 are included in this ATIS specification.

A common set of WEA requirements for the mobile device behavior will allow for a consistent user experience regardless of the associated wireless technology of the mobile device. Additionally, this common set of WEA requirements for the mobile device behavior will allow the various local, state, and Federal level government agencies to develop user WEA educational information that is independent of the wireless technology.
