Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Telec

15、ommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction NGN is intended to provide an efficient, secure and trustworthy numbering, naming and addressing environment for users, network operators and service providers. Evolution to NGN will ensure tha

16、t the sovereignty of ITU Member States with regard to numbering plan is fully maintained, as described in ITU-T Recommendation E.164 2. The present document is aligned with the definitions, based on recent ITU-T Recommendation E.101 1, and provides requirements and related solutions (i.e. formats an

17、d coding) for E.164 number used as NGNs and NGCNs Identifier for both IMS and not-IMS based on ETSI/3GPP standards. The present document looks at the description of the different E.164 numbers and requirements for numbering, naming and addressing in NGN and NGCN contexts considering that the existin

18、g dialling procedures (using TE) will be kept. ETSI ETSI TS 184 011 V3.1.1 (2011-02)51 Scope The present document provides an alignment of definitions on E.164 numbers, based on ITU-T Recommendation E.101 1. It provides requirements and describes the manner the numbers will be used within NGN and NG

19、CN environments. Naming issues related to NGCN are out of the scope for the moment. The support of national-only numbers is a national matter and is not addressed in the present document. The document deals with “geographic country codes“ (i.e. geographic areas or groups of countries) and their asso

20、ciated dialling plans, not with the international E.164 numbering plan as a whole. Non geographic country codes (such as country codes for networks) are not addressed in the present document. Clause 7 defines the normative statements for numbering use in NGN. 2 References References are either speci

21、fic (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies.

36、Universal Mobile Telecommunications System UNI User-Network-Interface URI Uniform Resource Identifier 4 Structure of Numbers Each country defines its own national numbering and the national dialling plan, based on ITU-T Recommendation E.164 2, as well as the prefixes and how the national formats (i.

37、e. the local and national level) are used. Subscribers in other countries are always reached by dialling the international prefix and the international E.164 number. International E.164 numbers are numbers based on ITU-T Recommendation E.164 2 and are used in different network environments like PSTN

38、, ISDN, and PLMNs based on GSM and UMTS, and are also used in NGNs as public identifiers. The international E.164 number uniquely identifies a subscriber or a point where a service is provided and satisfies the three characteristics of structure, number length and uniqueness as specified in E.164 2.

39、 The maximum number of digits for the E.164 number is 15 excluding the international prefix. International E.164 numbers are presently used in five different structures and these are described in detail in E.164 2: International E.164-number for geographic areas. International E.164-number for globa

40、l services. International E.164-number for Networks. International E.164-number for Groups of Countries. International E.164-number for Trials. The structure of the international E.164 number for geographic areas, as an example, is shown below taken from ITU-T Recommendation E.164 2: Figure 1: Inter

41、national E.164 number structure for geographic areas ETSI ETSI TS 184 011 V3.1.1 (2011-02)8An E.164 number of the own country can be used in different formats by the users and operators, the ones corresponding to: international level, national level and local level. Which of these formats are usable

42、 is dependant on the national E.164 numbering plan and the dialling plan. The following three notes describe the different formats which are national specifics: NOTE 1: International level: Some networks allow to dial the national E.164 numbers of the own country in the international format by using

43、 the international prefix. NOTE 2 National level: On the national level the number is used in the national (significant) number N(S)N format, i.e. the National Destination Code (NDC) and the Subscriber Number (SN), possibly together with the national (trunk) prefix. NOTE 3 Local level (Subscriber nu

44、mber): In some national dialling plans, using an open dialling plan, a user may also dial an E.164 number in the local format. This means dialling just the subscriber number (SN) without any national destination code. This dialling procedure might not be applicable in some countries and networks, us

45、ing closed dialling plans. In this case, there is always an NDC required to access other national E.164 numbers in the same area. Countries with a closed dialling plan do not have a local format. This may also be the case for certain networks (mostly mobile networks). In some countries with a closed

46、 dialling plan there is no NDC required to be dialled. 5 E.164 numbers formats and coding used in NGNs 5.1 General From the technical point of view, an ETSIs NGN is an IP-based network with control/service and transport layers and SIP signalling. E.164 numbers can be used to identify the users and s

47、ervice entities. From the signalling protocol point of view, E.164 numbers are conveyed using tel URI and/or SIP URI formats and coding (see 4, 5 and 7). As a consequence, for routeing purpose, tel URI and SIP URI have to be mapped to appropriate IP addresses, associated to control/service functiona

48、l entities, for communication establishing. In the ETSIs NGN context, both tel URI and SIP URI are to be considered the “naming“ schemes and SIP coding for E.164 numbers. The basic coding for E.164 numbers in SIP are the following: tel: for the purpose of the present document the is addressed by a “

49、global number“ or “local number“. sip: ;user=phone For the purpose of the present document the is an E.164 number. The shall be a string that identifies the operator serving the end user identified by the E.164 number on a contractual basis, following the rules on Internet domain names for the domain administration (see i.2 and i.3). Figure 2 describes the basic scenario that shows the exchange of E.164 format information at UNI and NNI in ETSI NGN functional architecture 9. ETS
