11、on ITU-T E.212 defines a unique international identification plan for public fixed and mobile networks providing users with access to public telecommunication services. The ITU-T E.212 identification plan was originally developed for use in public land mobile networks (PLMNs). The plan is hierarchic
12、al and identifies geographic areas, networks and subscriptions. The main body of this Recommendation describes the pure identification plan.

ITU-T E.212 (09/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technolog
16、ies (ICTs). The ITU 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 Telecommun
17、ication Standardization 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 o
18、f 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, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operati
19、ng agency. Compliance 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“
20、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 with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practic
21、e or implementation 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 developme
22、nt 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 implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore
23、strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2017 All rights reserved.

30、E.212 The international identification plan for public networks and subscriptions 1 Scope This Recommendation describes a unique and unambiguous identification plan for subscriptions and the format of the IMSI. It establishes procedures for the assignment of fields of the IMSI in a manner that preve
31、nts duplication. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

36、his Recommendation, it identifies a specific country, a group of countries in an integrated numbering plan or a specific geographical area. The terms “Operator“ and “National numbering plan administrator“ are defined in ITU-T E.101. This Recommendation defines the following terms: 3.1 home network:
37、The network responsible for the subscription identified by the elements within the IMSI. 3.2 international mobile subscription identity (IMSI): The IMSI is a string of decimal digits, up to a maximum length of 15 digits, which identifies a unique subscription. The IMSI consists of three fields: the
38、mobile country code (MCC), the mobile network code (MNC), and the mobile subscription identification number (MSIN). 3.3 mobile country code (MCC): The MCC is the first field of the IMSI and is three digits in length and identifies a country. The Director of TSB may assign more than one MCC to a coun
39、try. MCCs in the 90x range are non-geographic MCCs (country-agnostic) and are administered by the Director of TSB. 2 Rec. ITU-T E.212 (09/2016) 3.4 mobile network code (MNC): The MNC is the second field of the IMSI, it is two or three digits in length and is administered by the respective national n
40、umbering plan administrator. MNCs under MCC ranges 90x are administered by the Director of TSB. The MNC, in combination with the MCC, provides sufficient information to identify the home network. 3.5 mobile subscription identification number (MSIN): The MSIN is the third field of the IMSI, it is up
41、to 10 digits in length, and is administered by the relevant MNC assignee to identify individual subscriptions. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: IMSI International Mobile Subscription Identity MCC Mobile Country Code MNC Mobile Network Co
42、de MSIN Mobile Subscription Identification Number TSB Telecommunication Standardization Bureau UPT Universal Personal Telecommunication 5 Considerations The considerations that form the basis for this international identification plan for networks and subscriptions are as follows: a) The assignment
43、of E.212 resources is in conformance with the principles in ITU-T E.190. b) There may be more than one public network offering such services in a country. c) The MNC consists of 2 or 3 digits and the length of the MNC is a national matter. d) The number of digits of the MSINs is determined by the re
44、levant MNC assignee in accordance with the national policy. e) The IMSI shall not exceed 15 digits in length. f) For 90x MCCs, the length of MNCs is determined by the Director of TSB and the length of the MSINs is determined by the relevant MNC assignee in accordance with the relevant ITU-T Recommen
45、dations. g) The IMSI assigned to a subscription under this identification plan should not be directly related to numbers assigned to that same subscription under “The international public telecommunications numbering plan“ ITU-T E.164. h) The IMSI should, if necessary, enable: 1) determination of th
46、e home network; 2) identification of subscriptions, when information about a specific subscription is exchanged between networks; 3) identification of subscriptions for charging and billing purposes; 4) identification and management of subscription, e.g., for registering, authenticating, signalling,
47、 retrieving, providing, changing and updating of subscription data. i) The IMSI is not intended to be used for dialling purposes. This list is not exhaustive. Rec. ITU-T E.212 (09/2016) 3 6 IMSI structure, format and assignment procedures 6.1 Structure and format of the IMSI The IMSI structure and f
48、ormat are as shown in Figure 1. Figure 1 Structure and format of the IMSI 6.2 IMSI assignment procedures 6.2.1 The Director of TSB assigns MCCs in accordance with Annexes A and C. 6.2.2 MNCs associated with geographic MCCs are administered by the national numbering plan administrator within each cou
49、ntry in accordance with the principle in Annex B. 6.2.3 MSINs are administered by the relevant MNC assignee in accordance with relevant national or ITU-T Recommendations. 6.2.4 In principle, only one IMSI should be assigned to each subscription, although multiple subscriptions may be associated with a SIM/USIM/UICC/embedded SIM card. 4 Rec.
