22、 This Technical Report (TR) represents the results of the Study on Public Warning System (PWS). The intent of this study is to identify requirements and aspects for a Public Warning System. The regulatory requirements and use cases for a public warning service have not been finalized in all regions
23、(i.e. in the USA) therefore, the results of this study are not applicable for those regions which do not have regulatory requirements defined. The Public Warning System is intended to interwork with external networks to provide an end-to-end service. Therefore, service interactions with a Warning No
24、tification Provider in external networks are considered within the scope of this document, although the specification of these interactions may be in other standards. If this occurs, a reference to that specification shall be made. 2 References The following documents contain provisions which, throu
25、gh reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest ve
26、rsion applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 ETSI TS 102 182: “Emergenc

28、05 1 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 1. Notification Area: is an area where warning notifications are sent. Public Warning System: is a system that delivers Warning Notifications provided by W
29、arning Notification Providers to the UEs which have the capability of receiving Warning Notifications within Notification Areas through the 3GPP network. Public Warning Service: is a service that delivers Warning Notifications provided by Warning Notification Providers to the UEs which have the capa
30、bility of receiving Warning Notifications within Notification Areas through the 3GPP network. Warning Notification: is information which notifies users of the occurrence of the events and may provide users with additional information, such as instructions on what to do and or where to get help as lo
31、ng as the emergency lasts. Warning Notification Provider: is an agency (e.g. government and or public service organisations) that provide warning notifications and requests PLMN operators to deliver them.

33、ackground 4.1 Regional requirements The following sections provide a collection of regional requirements that may be applicable to the Public Warning System. The cellular system is expected to consider only those requirements of the PWS that are relative to the transmission to the UE of the warning
34、notification which is received from the relevant national/regional authority. 4.1.1 Japan The Japanese government intends to create early warning earthquake detection systems, which is called Earthquake Early Warning (EEW) System, during 2006 and expects that mobile operators study the feasibility o
35、f realizing a system for delivering earthquake early warning information to mobile phone users. An interim Japanese government report on the earthquake early warning information describes an idea of the requirements for the earthquake early warning information for the general public as follows: Eart
36、hquake early warning information should be published only once per occurrence of earthquake. Subsequent publication of the information should be avoided except for real necessity such as correction of wrong information, expansion of area where big earthquake is expected, etc Earthquake early warning
37、 information should be published only when occurrence of big earthquake is expected. Publication of wrong earthquake early warning information should be avoided. Earthquake early warning information should be published as soon as possible. Possible error in terms of accuracy should be taken into acc
38、ount in the expression of earthquake early warning information. Publication of earthquake early warning information can be limited to the area where evacuation is required. Earthquake early warning information should contain visual information for delivering through, for example, television. The fir
39、st six requirements are related to the use of the system and the last two requirements are related to the functionality of the system. The feasibility study in this TR needs to take the relevant requirements for the Public Warning System from the above list into account. 4.1.2 United States of Ameri
40、ca (USA) 4.1.2.1 WARN Act Summary On Friday October 13, 2006, the Warning Alert and Response Network (WARN) Act as part of the SAFE Port Act was signed by the U.S. President and became law. The WARN Act defines the process, procedures, and schedule for the development of the recommendations, require
41、ments, and regulations for the emergency alert systems for commercial wireless systems. The full text of the WARN Act is contained as Title VI Commercial Mobile Alert Systems of the Safe Port Act H.R.4954 and can be found at http:/thomas.loc.gov/cgi-bin/bdquery/z?d109:h.r.04954: ETSI ETSI TR 122 968
42、 V15.0.0 (2018-07)83GPP TR 22.968 version 15.0.0 Release 15Based upon the process, procedures, and schedule defined within the WARN Act, the FCC will not be issuing regulations for the wireless emergency alert systems in the United States until April 2008. Therefore, the 3GPP requirements for Public
43、 Warning Systems for the United States can not be completed until after April 2008. NOTE: The information included within brackets below are the references to the specific clauses of the WARN Act. Major Milestones of the WARN Act The major milestones that have been identified in the WARN Act are as
44、follows: - The FCC is to establish the Commercial Mobile Service Alert Advisory Committee (“Advisory Committee“) within 60 days of enactment Sec. 603.(a) - Membership in the Advisory Committee is by appointment of the FCC chairman Sec. 603.(b) - The Advisory Committee will be responsible for the dev
45、elopment of system-critical recommendations Sec. 603.(c) - The Advisory Committee is to develop recommendations for mobile alerts within one year of enactment Sec. 603.(c) - The FCC is to define the Commercial Mobile Service Regulations within 180 days after completion of recommendations by the Advi
46、sory Committee Sec. 602.(a) - The FCC is to amend commercial mobile service license within 120 days after the FCC modifies commercial mobile service regulations Sec. 602.(b)(1) - Since support of emergency alerts is voluntary, the mobile operators must file decisions on providing alert services with
47、in 30 days after FCC modifies commercial mobile service regulations Sec. 602.(b)(2)(A) The schedule of the WARN Act is portrayed on the following timeline: Oct-06 Dec-08Jan-07 Apr-07 Jul-07 Oct-07 Jan-08 Apr-08 Jul-08 Oct-08Oct-06WARN Act EnactmentDec-06FCC Establishes Advisory CommitteeApr-07FCC De
