Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols f

16、or Advanced Networking (TISPAN). Introduction The present document covers aspects how international E.164 numbers and E.164 numbers in the national formats should be treated in ETSI TISPAN NGNs. The present document also identifies further work how non-E.164 numbers should be treated. ETSI ETSI TR 1

17、84 005 V1.1.1 (2007-11) 5 1 Scope The present document describes the public identifiers, in the numeric format, used in NGNs: international E.164 numbers, E.164 numbers in the national formats and different types of non-E.164 numbers. It describes the processing of dialled digits to achieve these nu

18、mbers and the usage of all these kinds of numbers. For E.164 numbers also the processing to a target name in an NGN environment for further name/number to address translation is explained. The processing (treatment) of non-E.164 numbers is FFS but some initial discussion could be found in annex A. 2

30、trunk code (TC) that identifies a specific geographic part/numbering area of the national E.164 numbering plan closed dialling plan: dialling plan where the national (significant) numbers N(S)N are used when dialling geographic numbers dialling plan 1: string or combination of decimal digits, symbol

31、s, and additional information that defines the method by which the numbering plan is used. A dialling plan includes the use of prefixes, suffixes, and additional information, supplemental to the numbering plan, required to complete the call. global number: number defined in RFC 3966 3 in the format

32、of an international E.164 number emergency services: legally recognized service, reached via a national emergency number (e.g. 112), that provides immediate and rapid assistance in situations where there is a direct risk to life or limb, individual or public health or safety, to private or public pr

33、operty, or the environment but not necessarily limited to these situations international E.164 number 1: string of decimal digits that, for a geographic country code, uniquely identifies a subscriber or a point where a service is provided. For the case of a global service code, it identifies the sub

34、scriber of the service. For Networks, it identifies a subscriber of the Network. An international E.164 number can act in the “role“ of both a name and an address. Portability is reducing a numbers role as an address. Numbers are increasingly acting in the role of a name only. The number, which incl

35、udes the country code and subsequent digits, but not the international prefix, contains the information necessary to route the call to this termination point on a public network (it may also contain the supplementary information necessary to forward it on a private network). NOTE: It is sometimes re

36、ferred to as an “international number“, “international public telecommunication number“ or “E.164 number“. international prefix 1: digit or combination of digits used to indicate that the number following is an international E.164-number local number: number defined in RFC 3966 3 which is anything t

37、hat is not a global number and with the context defined. It can be E.164 numbers in the national formats or non-E.164 numbers. location dependent number: number that is routed through networks on the basis of calling party location MSISDN: mobile E.164 number used by the calling party to establish a

38、 call to the end user ETSI ETSI TR 184 005 V1.1.1 (2007-11) 7 national destination code (NDC 1: nationally optional code field, within the international public telecommunication numbering plan (hereafter referred to as the “international E.164-numbering plan“), which - combined with the Subscribers

39、Number (SN) - will constitute the national (significant) number of the international E.164-number for geographic areas. The NDC will have a network and/or trunk code selection function. The NDC can be a decimal digit or a combination of decimal digits (not including any prefix) identifying a numberi

40、ng area within a country (or group of countries included in one integrated numbering plan or a specific geographic area) and/or network/services. national (significant) number 1: that portion of the international E.164 number that follows the country code for geographic areas. The national (signific

41、ant) number consists of the National Destination Code (NDC) followed by the Subscriber Number (SN). The function and format of the N(S)N is nationally determined. national (trunk) prefix 1: digit or combination of digits used by a calling subscriber, making a call to a subscriber in his own country

42、but outside his own numbering area. It provides access to the automatic outgoing trunk equipment. non-E.164 number: any number, defined inside national E.164 numbering plan, which does not conform to the structure of international E.164 numbers as defined in ITU-T Recommendation E.164 1 and is only

43、used and meaningful in the national dialling plan and is not reachable from abroad NOTE: An explanation of non-E.164 numbers is in ITU-T Recommendation E.164 1 in annex A.8. number 9: number is a string of decimal digits numbering plan: plan that specifies the format and structure of the numbers use

44、d within telecommunication networks. The numbers in the plan can either have uniform length or variable length or include both numbers of uniform and variable length. E.164 numbering plan: E.164 numbering plan specifies the format and structure of the numbers. It typically consists of decimal (and h

45、exadecimal) digits segmented into groups in order to 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 requi

46、red to complete the call. The national E.164 numbering plan is the national implementation of the international E.164 numbering plan (sometimes called the international public telecommunication numbering plan). open dialling plan: dialling plan where both numbers on the local level (subscriber numbe

47、rs (SN) without area code) and numbers on the national level are used when dialling geographic numbers prefix 1: prefix is an indicator consisting of one or more digits, that allows the selection of different types of number formats, networks and/or services private numbering plan (PNP): numbering p

48、lan that specifies the format and structure of the numbers used within an organizations private/corporate/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 DDI. Public Safety Answering Point (PSAP): physical loc

49、ation where emergency calls are received under the responsibility of a public authority NOTE: Within the present document, it is assumed, unless stated otherwise, that PSAPs support the receipt of emergency calls over IP, using appropriate application layer protocols such as SIP for call signalling and RTP for media. PSAP URI: SIP AoR pointing to a PSAP public identifier: a series of digits, characters and symbols used in public networks to identify uniquely subscriber(s), user(s), network element(s), function(s) or
