10、on ITU-T E.212 The international identification plan for public networks and subscriptions Summary The purpose of Recommendation ITU-T E.212 is to define a unique international identification plan for public fixed and mobile networks providing users with access to public telecommunication services.
11、The E.212 identification plan was originally developed for the use in public land mobile networks (PLMN). The plan is hierarchical and identifies geographic areas, networks and subscriptions. The main body of this Recommendation describes the pure identification plan. Guidance on how to use this res
12、ource is described in the annexes. The international mobile subscription identities (IMSIs) are independent from the national numbering plans. In general, this Recommendation uses the term subscription because an IMSI identifies subscriptions for access to public telecommunication services. Source R

14、REWORD The International Telecommunication 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 studyi
15、ng technical, operating and tariff questions 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
16、 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 technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO
17、 and IEC. NOTE In this Recommendation, 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
18、 (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 obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such wor
19、ds 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 implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position con
20、cerning 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 the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by
21、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 consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

It establishes procedures for the assignment of fields of the IMSI in a manner that prevents dupl

36、country“, “destination country“ or “originating country“ is used in this Recommendation, it identifies a specific country, a group of countries in an integrated numbering plan or a specific geographical area. This Recommendation defines the following terms: 3.1 home network: The network of the opera
37、tor 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 mobile c
38、ountry 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 country. MCC
39、s in the 90x range are administered by the Director of TSB. 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 numbering plan administrator. The MNC, in combination with the MCC, provides sufficie
40、nt 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 to 10 digits in length, and is administered by the relevant operator to identify individual subscriptions. 2 Rec. ITU-T E.212 (05/2008) 3.6 national nu
41、mbering plan administrator: The organization (e.g., National Regulatory Authority/Administration) in charge of the administration of national naming, numbering and addressing plans. 3.7 operator: An operating agency providing public telecommunications networks or public telecommunication services. 4

43、Considerations The considerations that form the basis for this international identification plan for networks and subscriptions are as follows: a) The assignment 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 servic
44、es 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 relevant MNC assignee in accordance with the national policy. e) The IMSI shall not exceed 15 digits in length. f) For 90x MCCs, the length
45、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 Recommendations. g) The IMSI assigned to a subscription under this identification plan should not be directly related to numbers assigned to that
46、same subscription under “The international public telecommunications numbering plan“ ITU-T E.164. h) The IMSI should, if necessary, enable: 1) determination of the home network; 2) identification of subscriptions, when information about a specific subscription is exchanged between networks; 3) ident
47、ification of subscriptions for charging and billing purposes; 4) identification and management of subscription, e.g., for registering, authenticating, signalling, retrieving, providing, changing and updating of subscription data. i) The IMSI is not intended to be used for dialling purposes.

48、t is not exhaustive. Rec. ITU-T E.212 (05/2008) 3 6 IMSI structure, format and assignment procedures 6.1 Structure and format of the IMSI The IMSI structure and format are as shown in Figure 1.
