1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-1000061.2015 LTE Access Class 14 for National Security and Emergency Preparedness (NS/EP) Communications As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (ATIS) brings togeth
2、er the top global ICT companies to advance the industrys most pressing business priorities. ATIS nearly 200 member companies are currently working to address the All-IP transition, network functions virtualization, big data analytics, cloud services, device solutions, emergency services, M2M, cyber
3、security, network evolution, quality of service, billing support, operations, and much more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open source solutions, and intero
4、perability testing. ATIS is accredited by the American National Standards Institute (ANSI). The organization is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of the oneM2M global initiative, a member of and major U.S. contributor to t
5、he International Telecommunication Union (ITU), as well as a member of the Inter-American Telecommunication Commission (CITEL). For more information, visit www.atis.org. AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process
6、, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more tha
7、n a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, w
8、hether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any America
9、n National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the ti

13、ority treatment of NS/EP communications. 1.2 Purpose The purpose of this TR is to provide operational guidance regarding the assignment and use of the 3GPP LTE specifications for Access Class Barring to support National Security and Emergency Preparedness (NS/EP) Next Generation Network Priority-Ser
14、vices (NGN-PS). 3GPP TS 22.011 Section 4 contains the following general description of Access Classes: “All UEs are members of one out of ten randomly allocated mobile populations, defined as Access Classes 0 to 9. The population number is stored in the SIM/USIM. In addition, UEs may be members of o
15、ne or more out of 5 special categories (Access Classes 11 to 15), also held in the SIM/USIM. These are allocated to specific high priority users as follows. (The enumeration is not meant as a priority sequence): Class 15 - PLMN Staff; -“- 14 - Emergency Services; -“- 13 - Public Utilities (e.g. wate
16、r/gas suppliers); -“- 12 - Security Services; -“- 11 - For PLMN Use.” 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this Standard.

20、prove access for NS/EP NGN-PS subscribed UEs. NOTE: When during times of severe congestion for which access class barring need also be applied to the special Access Classes 10-15, AC 14 shall not be subject to barring until after AC 10, 11, 12, and 13 are subject to barring. This is done to provide priority to AC 14 over AC 10, 11, 12, and 13.
