11、164 numbers in the national numbering plans (NNPs) of all countries (i.e., each countrys application of Recommendation ITU-T E.164). This Recommendation also includes a method to make such NNP information available to all interested parties, as well as timely information on numbering plan changes th

This Recommendation also helps to collect other information that may be relevant, such as numbers related to important services like emergency services (emergency numbers) and services of social value, as w

ITU-T E.129 (01/2013) FOREWORD The International Telecommunic
14、ation Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff qu
15、estions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendati
16、ons on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation
17、, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability o
18、r applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance
19、 with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or a
20、pplicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to i

27、 ITU-T E.129 Presentation of national numbering plans 1 Scope This Recommendation assists numbering plan administrators by describing a methodology to access and provide ITU-T E.164 numbering information on their countrys national numbering plan (NNP) in a timely manner. Guidance includes, but is no
28、t limited to, methods on how to obtain information on national numbering plans, how to present and describe the numbering plans, and how to ensure the timely posting of numbering plan changes in a standardized presentation that is consistent with ITU-T E.164. While the basic objective of this Recomm
29、endation is to present geographic country code (CC) information, it may also be used to communicate numbering information for network code applications and for country codes assigned to groups of countries (GoC). In addition, this Recommendation helps to collect other information that may be relevan
30、t, such as numbers related to important services like emergency services (emergency numbers) and other services of social value1, as well as information on the implementation of number portability (NP) of ITU-T E.164 numbers. 2 References The following ITU-T Recommendations and other references cont

38、culties in gaining access to information on newly assigned and implemented numbering resources on a worldwide basis. To meet this need, this Recommendation presents and identifies a process for worldwide notification of new assignments and changes of ITU-T E.164 numbers in the NNPs. In addition, the
39、 applicability of number portability (NP) and the assignment of important numbers within a specific jurisdiction are essential information to be shared. Therefore, notification of applicability of NP in each country is also included in this process, although it is recognized that NP may not have bee
40、n implemented in every country. Reference is also made to numbers defined in the national numbering plan for allocation to important services like emergency services and services of social value. A request for assistance in providing and receiving worldwide information on operation and numbering was
41、 addressed to numbering plan administrators (NPAs). As a result, this Recommendation has been developed to provide a solution to the problem of disseminating national operational and numbering information, including requirements associated with the use of ITU-T E.164 numbers, like the implementation
42、 of NP and important numbers such as those allocated to emergency services and services of social value. ITU-T has been involved in this process and the efforts of the Telecommunication Standardization Bureau (TSB) are integral to its implementation and success. 6 Description of approach and recomme
43、nded solution To meet the objectives of this Recommendation, a standardized methodology is herein described to recommend: Rec. ITU-T E.129 (01/2013) 3 a) the gathering of Internet web addresses and hyperlinks, made available on the ITU-T home page entitled “International Numbering Resources“, to acc
44、ess the websites of national numbering plan administrators to obtain descriptions of national numbering plan(s). b) the gathering of Internet web addresses and hyperlinks, made available on the ITU-T home page entitled “Implementation of Number Portability“, to access the websites of national number
45、ing plan administrators to obtain descriptions of each countrys number portability. c) a standardized format to describe a countrys implementation of emergency numbers and other important numbers related to services of social value. This information can be posted on the national numbering plan admin
46、istrators website. d) a standardized format to post and describe changes to a countrys numbering plan. This information will be posted on the ITU-T website under the specific country to which it applies. e) a standardized format to describe a countrys implementation of number portability and a forma
47、t to post this information on the ITU-T website. f) a method to inform all requesting parties to subscribe and participate in an e-mail exploder list that will announce relevant changes to a countrys numbering plan and number portability implementation. The remainder of this Recommendation expands o
48、n these objectives and describes how they are implemented. 7 ITU-T website and exploder list 7.1 General The ITU-T website is a critical component in the successful application of the solution to provide free, accurate and timely access to the most current international numbering information.
