Description / Abstract:

The scope of this standard is the support of eWEA via the EPSPWS. This standard covers the mapping of eWEA messages onto the 3rd Generation Partnership Project (3GPP)-defined PWS message structure within the EPS.

The support of eWEA via the Evolved Multicast Broadcast Multimedia Service (eMBMS) is beyond the scope of this Standard.

This standard is not intended to describe an overall end-to-end eWEA or PWS architecture and may include clarifications that may be lacking in existing 3GPP specifications.

The eWEA interface with the Federal network and the mobile device behavior upon reception of a eWEA alert are specified in separate standards [Ref 10, Ref 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 EPS PWS for the delivery of eWEA messages. The standard includes the mapping of eWEA application level messages to the Cell Broadcast Center (CBC) message structure as used within the EPS.
