Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Special Mobile Group (SMG). The present document defines the plans and principles of numbering, addressing and identification within the European digital cellular telecommunications system (Phase 2). The present document corresponds to GSM Technical Specification (GSM-TS) GSM 03.03 version 4.9.0. The specification from which the present document has been derived was originally based on CEPT documentation, hence the presentation of the present document may not be entirely in accordance with the ETSI/PNE rules.
Reference is made within the present document to GSM-TSs (NOTE). NOTE: TC-SMG has produced documents which give the technical specifications for the implementation of the European digital cellular telecommunications system. Historically, these documents have been identified as GSM Technical Specifications (GSM-TSs). These TSs may have subsequently become I-ETSs (Phase 1), or ETSs (Phase 2), whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are, for editorial reasons, still referred to in GSM ETSs.

[11] CCITT Recommendation X.121: "International numbering plan for public data networks". 1.3 Definitons and abbreviations Abbreviations used in the present document are listed in GSM 01.04. 1.4 General comments to references The identification plan for mobile subscribers defined below is that defined in CCITT Recommendation E.212. The ISDN numbering plan for mobile stations and the allocation of mobile station roaming numbers is that defined in CCITT Recommendation E.213. Only one of the principles for allocating ISDN numbers is proposed for GSM PLMNs. Only the method for allocating mobile station roaming numbers contained in the main text of CCITT Recommendation E.213 is recommended for use in GSM PLMNs. If there is any difference between this Technical Specification and the CCITT Recommendations, the former shall prevail. For terminology, see also CCITT Recommendations E.164 and X.121. 1.5 Conventions on bitordering The following conventions hold for the coding of the different identities appearing in this Technical Specification and in other GSM Technical Specifications if not indicated otherwise:
- the different parts of an identity are shown in the figures in order of significance; - the most significant part of an identity is on the left part of the figure and the least significant on the right. When an identity appears in other Technical Specifications, the following conventions hold if not indicated otherwise:
- digits are numbered by order of significance, with digit 1 being the most significant; - bits are numbered by order of significance, with the lowest bit number corresponding to the least significant bit. 2 Identification of mobile subscribers 2.1 General A unique International Mobile Subscriber Identity (IMSI) shall be allocated to each mobile subscriber in the GSM system. NOTE: This IMSI is the concept referred to by CCITT as "International Mobile Station Identity". In order to support the subscriber identity confidentiality service the VLRs may allocate a unique Temporary Mobile Subscriber Identity (TMSI) to visiting mobile subscribers. The VLR must be capable of correlating the IMSI of an MS and the current TMSI for that MS. In order to speed up the search for subscriber data in the VLR a supplementary Local Mobile Station Identity (LMSI) is defined. The LMSI may be allocated by the VLR at location updating and is sent to the HLR together with the IMSI. The HLR makes no use of it but includes it together with the IMSI in all messages sent to the VLR concerning that MS. SIST EN 300 523 V4.11.1:2003

Figure 1: Structure of IMSI IMSI is composed of three parts: i) Mobile Country Code (MCC) consisting of three digits. The MCC identifies uniquely the country of domicile of the mobile subscriber; ii) Mobile Network Code (MNC) consisting of two digits for GSM applications. The MNC identifies the home GSM PLMN of the mobile subscriber; iii) Mobile Subscriber Identification Number (MSIN) identifying the mobile subscriber within a GSM PLMN. The National Mobile Subscriber Identity (NMSI) consists of the Mobile Network Code and the Mobile Subscriber Identification Number. 2.3 Allocation principles IMSI shall consist of numerical characters (O through 9) only. The overall number of digits in IMSI shall not exceed 15 digits. The allocation of Mobile Country Codes (MCCs) is administered by the CCITT and is given in Annex A to CCITT Blue Book Recommendation E.212. The allocation of National Mobile Subscriber Identity (NMSI) is the responsibility of each administration. If more than one GSM PLMN exist in a country, a unique Mobile Network Code should be assigned to each of them. The allocation of IMSIs should be such that not more than the digits MCC + MNC of the IMSI have to be analysed in a foreign GSM PLMN for information transfer. 2.4 Structure of TMSI Since the TMSI has only local significance (i.e. within the VLR and the area controlled by the VLR), the structure and coding of it can be chosen by agreement between operator and manufacturer in order to meet local needs. The TMSI consists of 4 octets. It can be coded using a full hexadecimal representation. In order to avoid double allocation of TMSIs after a restart of a VLR, some part of the TMSI may be related to the time when it was allocated or contain a bit field which is changed when the VLR has recovered from the restart. The TMSI shall only be allocated in ciphered form. See also Technical Specification GSM 03.20. The newtwork shall not allocate a TMSI with all 32 bits equal to 1 (this is because the TMSI must be stored in the SIM, and
the SIM uses 4 octets with all bits equal to 1 for indicating that no valid TMSI is available. SIST EN 300 523 V4.11.1:2003

Also the structure of mobile station roaming numbers is defined. One or more numbers of the ISDN numbering plan shall be assigned to a mobile station to be used for all calls
