1、 ATIS-0700033 ATIS Standard on - ATIS Supplement C to J-STD-101, Joint ATIS/TIA CMAS Federal Alert Gateway to CMSP Gateway Interface Specification ATIS-0700033 ii Foreword The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between carriers,

2、customers, and manufacturers. The Wireless Technologies and Systems Committee (WTSC) develops and recommends standards and technical reports related to wireless and/or mobile services and systems, including service descriptions and wireless technologies. WTSC develops and recommends positions on rel

3、ated subjects under consideration in other North American, regional, and international standards bodies. The mandatory requirements are designated by the word shall and recommendations by the word should. Where both a mandatory requirement and a recommendation are specified for the same criterion, t

4、he recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages. The word may denotes an optional capability that could augment the standard. The standard is fully functional without the incorporation of this optional capability. Suggestions for

5、improvement of this document are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, WTSC 1200 G Street NW, Suite 500, Washington, DC 20005. At the time of consensus on this document, WTSC, which was responsible for its development, had the following leadership: D

Specifically, the Federal Alert Gateway will only generate CMAMs for Presidential alerts, Imminent Threat Alerts (where the corresponding CAP message Severity is extreme or severe, Urgency is immedi

19、ate or expected, and Certainty is observed or likely), or a Child Abduction Emergency/AMBER Alert. Alerts not meeting this classification will not be sent over Reference Point “C”.

46、ditions 3.1 Addition of New Preface Clause The following new Preface is added after the Table of Contents and before Clause 1, Introduction: Preface The authority-to-individuals emergency alerting capability to mobile devices was originally called Commercial Mobile Alert System (CMAS) in the first t

47、hree Reports and Orders from the FCC. This standard was originally developed based upon the CMAS terminology and CMAS was operational in April 2012. However, in February 2013, the FCC renamed Commercial Mobile Alert System (CMAS) to Wireless Emergency Alerts (WEA) with associated updates to the appr

48、opriate sections of Part 11 of the 47 CFR. Subsequently, the FCC has issued additional enhancements and rules for this government-to-citizen emergency alerting capability to mobile devices capability and these are identified as modifications to WEA. Consequently, this specification may use both the

49、term CMAS and the term WEA. These terms should be considered as equivalent terms with WEA being the preferred term. 3.2 Addition of New Ref 41 in Clause 2, Normative References An additional reference Ref 41 is added to Clause 2, Normative References, as shown below: Ref 41 FCC 16-127, Federal Communications Commission Report and Order and Further Notice of Proposed Rulemaking In the Matter of Wireless Emergency Alerts Amendments to Part 11 of the Commission
