Scope
The scope of this standard is the support of Commercial Mobile Alert System (CMAS) via the Evolved Packet System (EPS) Public Warning System (PWS). This standard covers the mapping of CMAS messages onto the 3GPP-defined Public Warning System (PWS) message structure within the EPS. The support of CMAS 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 CMAS or PWS architecture and may include clarifications that may be lacking in existing 3GPP specifications. The CMAS interface with the Federal network and the mobile device behavior upon reception of a CMAS alert are specified in separate standards [Ref 10@ Ref 9]. NOTE: The Joint ATIS/TIA CMAS Mobile Device Behavior Specification [Ref 9] also supports the CMAS functionality of this Standard even though this access technology is not explicitly referred in the CMAS mobile device behavior specification. Purpose The purpose of this standard is to describe the use of the Evolved Packet System (EPS) Public Warning System (PWS) for the delivery of Commercial Mobile Alert System (CMAS) messages. The standard includes the mapping of CMAS application level messages to the Cell Broadcast Center (CBC) message structure as used within the EPS.
