scope:

The scope of this standard is to provide implementation guidelines for the Commercial Mobile Service Provider (CMSP) handling of Commercial Mobile Alert System (CMAS) supplemental information broadcast for GSM, UMTS, and E-UTRAN systems.

ATIS-0700006 [Ref 2], ATIS-0700009 [Ref 4], and ATIS-0700010 [Ref 5] specify the CMSP handling of CMAS messages using Cell Broadcast Service (CBS) capabilities for GSM/UMTS and E-UTRA systems.

Purpose

This standard defines the implementation guidelines for the CMSP handling of CMAS supplemental information broadcast.

Application

While English-only CMAS messages are required per the FCC First Report and Order [Ref 7], the WARN Act states that commercial mobile service providers who elect to transmit emergency alerts may transmit in languages in addition to English, to the extent practical and feasible. To support this WARN Act option, the CMSP Gateway shall have the capability to retrieve CMAS message text in Spanish.

A CMSP shall define its own policy for the retrieval and transmission of CMAS messages in languages other than English. This CMSP policy includes whether to transmit the CMAS message in languages other than English and which geographic areas (e.g., region) to transmit in languages other than English.
