22、r) is a Commercial Mobile Service Provider that has voluntarily elected to transmit Alert Messages. 7This document is available from the Internet Engineering Task Force (IETF). ATIS-0700006.v002 4 3.2 Acronyms Emergency alert formatting, classes, and elements: Participating CMS Providers must transm
23、it three classes of alerts - Presidential, Imminent Threat, and AMBER alerts; Geographic targeting (geo-targeting): Participating CMS Providers generally are required to target alerts at the county-level as recommended by the CMSAAC; Accessibility for people with disabilities and the elderly: Partic
24、ipating CMS Providers must include an audio attention signal and vibration cadence on CMAS-capable handsets; Multi-language Alerting: Participating CMS Providers will not be required at this time to transmit alerts in languages other than English; Availability of CMAS alerts while roaming: Subscribe
25、rs receiving services pursuant to a roaming agreement will receive alert messages on the roamed upon network if the operator of the roamed upon network is a Participating CMS provider and the subscribers mobile device is configured for and technically capable of receiving alert messages from the roa
26、med upon network; and Preemption of calls in progress: CMAS alerts may not preempt a voice or data session in progress. The First Report and Order Ref 1 specifies rules governing those sections of the eWEA architecture that are within the control of electing CMS providers. These include the CMS Prov
27、ider Gateway, CMS provider infrastructure, and CMS provider handsets. The rules require each individual CMS Provider Gateway to be able to receive alerts from the Federal Alert Gateway over a secure interface (i.e., Reference Point “C” Interface). NOTE: On July 14, 2008, the FCC issued an Order on R
28、econsideration and Erratum Ref 14. 4.2.2 FCC Second Report and Order The FCC released the Second Report and Order for the Commercial Mobile Alert System on July 8, 2008 Ref 12. In the Second Report and Order, the FCC developed rules to be in compliance with section 602(c) of the WARN Act, which requ
29、ire non-commercial educational (NCE) and public broadcast television station licensees and permittees “to install necessary equipment and technologies on, or as part of, any broadcast television digital signal transmitter to enable the distribution of geographically targeted alerts by commercial mob
30、ile service providers that have elected to transmit emergency alerts”. 19WARN Act 602(e)(1)(B). ATIS-0700006.v002 7 The Second Report and Order also defines rules to implement Section 602(f) of the WARN Act, which requires “technical testing for commercial mobile service providers that elect to tran
31、smit emergency alerts and for the devices and equipment used by such providers for transmitting such alerts”. This technical testing is defined by the FCC rules to be a “Required Monthly Test” and “Periodic Interface Testing”. The Required Monthly Test (RMT) is initiated by the Federal Alert Gateway
32、 Administrator and defines rules for the CMSP to schedule the distribution of the RMT to their WEA coverage area over a 24-hour period, commencing upon receipt of the RMT at the CMSP Gateway. A CMSP may provide mobile devices with the capability of receiving RMT messages. A Participating CMS Provide
33、r may provide mobile devices with the capability of receiving Required Monthly Test (RMT) messages. The FCC does not require that CMS providers make available mobile devices that support reception of the required monthly test. The FCC does, however, allow CMS providers to choose to do so. CMS provid
34、ers that choose not to make the required monthly test available to subscribers must find alternate methods of ensuring that subscriber handsets will be able to receive WEA alert messages. These alternative methods are beyond the scope of these standards. The Periodic Interface Testing is a test mess
35、age between the Federal Alert Gateway and the CMSP Gateway and is intended to ensure the availability/viability of both gateway functions. The Periodic Interface Test is not designed to test the CMSPs infrastructure nor the mobile devices. The CMSP Gateway shall send an acknowledgement to the Federa
36、l Alert Gateway upon receipt of such an interface test message. 4.2.3 FCC Third Report and Order The FCC released the Third Report and Order for the Commercial Mobile Alert System on August 7, 2008 Ref 13. In the Third Report and Order, the FCC adopted rules implementing Section 602(b) of the WARN A
37、ct. Specifically, the Third Report and Order adopts: Notification requirements for CMS providers that elect not to participate, or to participate only in part, with respect to new and existing subscribers; Procedures by which CMS providers may elect to transmit emergency alerts and to withdraw such
38、elections; A rule governing the provision of alert opt-out capabilities for subscribers; and A compliance timeline under which participating CMS providers must begin CMAS deployment. The rule governing the provision of alert opt-out capabilities for subscribers specifies: CMS providers may provide t
39、heir subscribers with the option to opt out of both, or either, the “Child Abduction Emergency/AMBER Alert” and “Imminent Threat Alert” classes of Alert Messages. CMS providers shall provide their subscribers with a clear indication of what each option means, and provide examples of the types of mes
40、sages the customer may not receive as a result of opting-out. Requirements and specifications for the subscribers right to opt out as defined in the Third Report and Order may be found in ATIS-0700036, eWEA MDB Specification Ref 9. 4.2.4 FCC Report and Order on WEA Enhancements On September 29, 2016
41、, the FCC issued the FCC Report therefore, from an architectural perspective, there shall only be a single interface between each BSC/RNC and multiple CBCs. In other words, when multiple CBCs are deployed for redundancy, they shall appear as one logical CBC from each BSC/RNC perspective. 3. The CBC
42、to RNC interface shall follow the existing primitives in the 3GPP TS25.419 Ref 3 specification. ATIS-0700006.v002 12 5.5 Lawful Interception Requirements There are no lawful interception requirements for WEA, as all WEA messages are generated by the government and are disseminated to the public. WEA
43、 messages are not specific to a target or subject of an interception. No new or existing network Intercept Access Points are expected to intercept WEA messages. 5.6 Discontinuous Reception Requirements Support of the Cell Broadcast Service Discontinuous Reception (DRX) shall be mandatory for both th
44、e network and mobile devices for both GSM and UMTS. In 3GPP TS 23.041 Ref 2, DRX is optional in GSM and mandatory in the RNC for UMTS; in order to minimize the impact battery life, both GSM and UMTS networks and mobile devices that support WEA shall be required to support the DRX mode. 6 Functional
45、Architecture and Interfaces Reference Points “D” Cell Broadcast Service Protocol (CBSP) Ref 19 may be used as the protocol between the CBC and BSC. 6.2 CBC to RNC Interface For the support of Cell Broadcast via UMTS, 3GPP has defined a mandatory protocol between the CBC and RNC in 3GPP TS 25.419 Ref
46、 3. 6.3 CMSP Gateway to CBC Interface The interface between the CMSP Gateway and the CBC is defined in ATIS-0700008 Ref 16. 7 eWEA Call Flows This clause provides call flows for the eWEA functionality. These call flows assume that the delivery technology will be Cell Broadcast Service as defined in
47、3GPP TS 23.041 Ref 2. Example call flows for eWEA application using GSM/UMTS Cell Broadcast Service are provided in ATIS-0700007, Implementation Guidelines and Best Practices for GSM/UMTS Cell Broadcast Service Ref 4. The CMSP Gateway is a Cell Broadcast Entity (CBE) and the interface to the CBC is
48、specified in ATIS-0700008 Ref 16. eWEA does not modify the Cell Broadcast functionality as defined in 3GPP TS 23.041 and other referenced 3GPP specifications. The following eWEA call flows are defined in this clause: New eWEA alert message call flow. Updated eWEA alert message call flow. Cancelled e
49、WEA alert message call flow. Invalid eWEA alert message call flow. ATIS-0700006.v002 14 7.1 New eWEA Alert Message Call Flow The following is the call flow for a new eWEA Alert Message: CMSPGatewayCBCMobileDevice3. eWEA Alert Message sent to CBC4. eWEA Alert Message validated5. eWEA Alert Message acknowledged6.
