The FCC CMAS First Report and Order 132 specifies the rules and architecture for CMAS. The FCC CMAS Second Report and Order 133 establishes CMAS testing requirements and describes the optional capability for Noncommercial Educational (NCE) and public broadcast television stations distribute geo-targeted CMAS alerts. The FCC CMAS Third Report and Order 134 defined the CMAS timeline, subscriber notification requirements for CMSPs, procedures for CMSP participation elections and the rules for subscriber opt-out. The FCC also issued a CMAS Reconsideration and Erratum document 135 between the issuance of the second and third Report & Order documents. The CMAS network will allow the Federal Emergency Management Agency (FEMA), to accept and aggregate alerts from the President of the United States, the National Weather Service (NWS), and state and local emergency operations centers, and then send the alerts over a secure interface to participating commercial mobile service providers (CMSPs). These participating CMSPs will then distribute the alerts to their users. As defined in the FCC CMAS Third Report and Order, CMSPs that voluntarily choose to participate in CMAS must begin an 18 month period of development, testing and deployment of the CMAS no later than ten months from the date that the Government Interface Design specifications available. On December 7, 2009, the CMAS timeline of the FCC CMAS Third Report and Order was initiated with the announcement 136 by FEMA and the FCC that the Joint ATIS/TIA CMAS Federal Alert GW to CMSP GW Interface Specification (J-STD-101) has been adopted as the Government Interface Design specification referenced in the FCC CMAS Third Report and Order. Participating CMSPs must be able to target alerts to individual counties 137 and ensure that alerts reach customers roaming outside a provider’s service area. Participating CMSPs must also transmit alerts with a dedicated vibration cadence and audio attention signal. Emergency alerts will not interrupt calls in progress. CMAS supports only English text-based alert messages with a maximum displayable message size of 90 English characters. For purposes of CMAS, emergency alerts will be classified in one of three categories: 1. Presidential Alerts. Any alert message issued by the President for local, regional, or national emergencies and are the highest priority CMAS alert 2. Imminent Threat Alerts. Notification of emergency conditions, such as hurricanes or tornadoes, where there is an imminent threat to life or property and some immediate responsive action should be taken 3. Child Abduction Emergency/AMBER Alerts. Alerts related to missing or endangered children due to an abduction or runaway situation 132 FCC 08-99, Federal Communications Commission First Report and Order In the Matter of The Commercial Mobile Alert System, Federal Communications Commission, 9 April 2008, . 133 FCC 08-164, Federal Communications Commission Second Report and Order and Further Notice of Proposed Rulemaking In the Matter of The Commercial Mobile Alert System, 8 July 2008, . 134 FCC 08-184, Federal Communications Commission Third Report and Order and Further Notice of Proposed Rulemaking In the Matter of The Commercial Mobile Alert System;7 August, 2008 and is available from the Federal Communications Commission. . 135 FCC 08-166, Federal Communications Commission Order on Reconsideration and Erratum In the Matter of The Commercial Mobile Alert System, 15 July 2008 and is available from the Federal Communications Commission. . 136 http://www.fema.gov/news/newsrelease.fema?id=50056. 137 The county geocode information will be present in all CMAS alert messages sent to CMSPs. If available, more granular geographic targeting information such as polygons or circles will be included in the CMAS messages. It is a voluntary option of the CMSPs to use the finer granular geographic targeting information. www.4gamericas.org February 2011 Page 116
The subscribers of participating CMSPs may opt out of receiving Imminent Threat and Child Abduction/AMBER alerts, but cannot opt out from Presidential Alerts. The following figure shows the CMAS Reference Architecture as defined in the FCC CMAS First Report and Order: Figure B.1. CMAS Reference Architecture. 138 Reference Point C is the secure interface between the Federal Alert GW and the Commercial Mobile Service Provider (CMSP) GW. The Reference Point C interface supports delivery of new, updated or canceled wireless alert messages, and supports periodic testing of the interface. This interface is defined in the J-STD-101, the Joint ATIS/TIA CMAS Federal Alert GW to CMSP GW Interface Specification. 139 J-STD-101 defines the interface between the Federal Alert GW and the Commercial Mobile Service Provider (CMSP) GW for CMAS alerts. This standard is applicable to CMSPs and to the Federal Government entity (i.e. FEMA) responsible for the administration of the Federal Alert GW. FEMA will perform the function of aggregating all state, local, and federal alerts and will provide one logical interface to each CMSP who elects to support CMAS alerts. For GSM and UMTS systems, wireless alert messages that are received by CMSP GWs will be transmitted to targeted coverage areas using GSM-UMTS Cell Broadcast Service (CBS). The CMAS functionality does not require modifications to the 3GPP-defined CBS. The ATIS WTSC-G3GSN Subcommittee is developing the CMAS via GSM-UMTS Cell Broadcast Service (CBS) Specification. 140 The purpose of this standard is to describe the use of the GSM-UMTS Cell 138 Notice of Proposed Rulemaking, In the Matter of The Commercial Mobile Alert System, FCC 07-214, 14 December 2007. 139 J-STD-101, Joint ATIS/TIA CMAS Federal Alert Gateway to CMSP Gateway Interface Specification, Alliance for Telecommunications Industry Solutions (ATIS), October 2009, . 140 ATIS-0700006, ATIS CMAS via GSM/UMTS Cell Broadcast Service Specification. www.4gamericas.org February 2011 Page 117
