12、istory Edition Recommendation Approval Study Group 1.0 ITU-T E.101 2009-11-24 2 ii Rec. ITU-T E.101 (11/2009) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The I

13、TU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardi

14、zation Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations 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 tec

15、hnology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compli

16、ance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obli

17、gatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementati

18、on of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of

19、 the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to

ITU-T E.101 (11/2009) 1 Recommendation ITU-T E.101 Definitions of terms used for identifiers (names, numbers, addresses and other identifiers) for public telecommunication services and networks in the E-series Recommendations 1 Scope/Introduction This Recommen

23、dation provides terms and definitions for use in the field of identifiers (e.g., names, numbers, addresses and other identifiers (IDs) for public telecommunication services and networks. The purpose of this set of definitions is to aid in the understanding of different IDs used in different telecomm

24、unication networks and related Recommendations. Consistent terminology is seen as an important factor in ITU-T Recommendations, especially in Recommendations having some form of regulatory implications. For the area covering Identifiers, there are important Recommendations in the E-/F-series, but al

25、so in the Q- and X-series. The E-/F-series Recommendations falls under the responsibility of Study Group 2 (SG 2) and the Q-series is under SG 11, and SG 13 covers the X-series Recommendations. These terms and definitions have been developed, for the most part, from the practice of the use of IDs in

26、 traditional telephone networks such as PSTN, ISDN and PLMN-based networks (e.g., 1G and 2G). These terms will continue to be applicable with their current definitions for other telecommunication networks like NGNs, 3G-based PLMNs and other IP-based networks. Alternatives for the preferred terms are

27、 given following a semi-colon. The listings of the terms contain the following: Definition of terms for different types of plans (clause 3). Definition of generic terms for resources used in the plans (clause 4). Definition of terms for specific resources used in the plans (clause 4). Definition of

28、terms for the structure and sub-parts of specific resources (clause 5). Definition of terms concerning administrative aspects for plans and resources (clause 6). Every time a new Recommendation within the E-series is developed or an existing Recommendation is modified or deleted, this Recommendation

29、 shall be reviewed accordingly to ensure the information is accurate and up to date. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

36、consists of terms for different naming, numbering and addressing plans. The concept diagram below gives an example of some of these plans.

37、 Identificationplan E.212 Identificationplan Dialling planClosed diallingplan Open diallingplan F03.doc3.1 addressing plan: An addressing plan specifies the format and structure of addresses used within that plan. 3.2 closed dialling plan: A dialling plan where the national (significant) numbers N(S

38、)N are used when dialling geographic numbers. 3.3 dialling plan ITU-T E.164: A string or combination of decimal digits, symbols, and additional information that defines the method by which the numbering plan is used. A dialling plan Rec. ITU-T E.101 (11/2009) 3 includes the use of prefixes, suffixes

39、, and additional information, supplemental to the numbering plan, required to complete the call. 3.4 E.164 numbering plan: A type of numbering plan that specifies the format and structure of the numbers used within that plan. It typically consists of decimal digits segmented into groups in order to

40、identify specific elements used for identification, routing and charging capabilities, e.g., to identify countries, national destinations and subscribers. An E.164 numbering plan does not include prefixes, suffixes, and additional information required to complete a call. The national numbering plan

41、(NNP) is the national implementation of the international E.164-numbering plan (also called the international public telecommunication numbering plan). 3.5 identification plan: A plan that specifies the format and structure of non-dialable identifiers for telecommunication networks used for network

42、functions/elements/equipment or used for other administrative aspects of networks. 3.6 naming plan: A plan that specifies the format and structure of the names used within telecommunication networks. 3.7 numbering plan: A plan that specifies the format and structure of the numbers used within teleco

43、mmunication networks. The numbers in the plan can either have uniform length or variable length or include both numbers of uniform and variable lengths. 3.8 open dialling plan: A dialling plan where both numbers on the local level (subscriber numbers (SN) without area code) and numbers on the nation

44、al level are used when dialling geographic numbers. 3.9 plan; scheme: A plan/scheme specifies the format and structure of identifiers used within a telecommunication network. 3.10 private numbering plan (PNP): A numbering plan that specifies the format and structure of the numbers used within an org

45、anizations private/enterprise telecommunication network. PNPs may be wholly separate from the E.164 numbering plan or may overlap with it, e.g., in the case of direct-dial-in (DDI). 4 Definitions of terms for generic and specific resources used in the plans This clause consists of terms for generic

46、and specific resources used in the different plans. The concept diagram below gives an example of different identifiers mostly from the E.164 numbering plan.

48、k. 4.2 code: A character or a sequence of characters, digits or symbols used as an identifier. 4.3 domain name ITU-T E.910: An alphanumeric name that, when combined with an Internet top level domain (TLD), represents a unique name which is the sequence of labels from the node at the root of the doma

49、in to the root of the whole tree, with dots separating the labels. 4.4 E.164 number: A string of decimal digits that satisfies the three characteristics of structure, number length and uniqueness specified in ITU-T E.164. The number contains the information necessary to route the call to the end user or to a point where a service is provided. 4.5 emergency number: A national-only number allocated in the national numbering plan to enable emergency calls. Normally, the emergency number is a short code. Cou
