Description / Abstract:

The scope of this standard is the support of Enhanced Wireless Emergency Alert (eWEA) via the Global System for Mobile Communications (GSM)/Universal Mobile Telecommunications System (UMTS) Cell Broadcast Service. This standard covers the mapping of eWEA messages onto the 3GPP-defined Cell Broadcast Service.

This standard is not intended to describe an overall end-to-end eWEA or Cell Broadcast architecture and may include clarifications of Cell Broadcast Service that may be lacking in existing 3GPP specifications. The implementation guidelines and best practices for the Cell Broadcast Service are provided in a separate ATIS Standard [Ref 4] which contains clarifications applicable to any application that uses the Cell Broadcast Service and is not necessarily restricted to eWEA.

eWEA does not require modifications to the 3GPP-defined Cell Broadcast Service.

The eWEA interface with the Federal network and the mobile device behavior upon reception of a eWEA alert is specified in separate standards [Ref 8 and 9].

NOTE: ATIS-0700036, eWEA Mobile Device Behavior (MDB) Specification (a revised version of J-STD-100) [Ref 9], also supports the eWEA functionality of this Standard even though this access technology is not explicitly referred in the eWEA mobile device behavior specification.


The purpose of this standard is to describe the use of the GSM/UMTS Cell Broadcast Service for the broadcast of eWEA messages. The standard includes the mapping of eWEA application level messages to the Cell Broadcast Service message structure.
