[11] CCITT Recommendation X.121: "International numbering plan for public data networks". 1.2 Abbreviations Abbreviations used in the present document are listed in GSM 01.04. 1.3 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 MSs 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 MS 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. 1.4 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 300 927 V5.4.1:2003



ETSI (GSM 03.03 version 5.4.1 Release 1996)8ETSI EN 300 927 V5.4.1 (2000-12)2.2 Composition of IMSI IMSI is composed as shown in figure 1. MCCNot more than 15 digits3 digits2 digitsMNCMSINNMSIIMSI 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 GSM 03.20. The network 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.

ETSI ETSI EN 300 927 V5.4.1 (2000-12)9(GSM 03.03 version 5.4.1 Release 1996)2.5 Structure of LMSI The LMSI consists of 4 octets and may be allocated by the VLR. 3 Numbering plan for mobile stations 3.1 General Below the structure of the numbers used by a subscriber of a fixed (or mobile) network for calling a MS of a GSM PLMN is defined. Also the structure of MS roaming numbers is defined. One or more numbers of the ISDN numbering plan shall be assigned to a MS to be used for all calls to that station. There may be a need for Mobile Stations (MS) to have a X.121 number. Because the MS has to have in any case a number from the ISDN numbering plan, the X.121 number will be in addition. Implications on numbering interworking functions which may need to be provided by the PLMN (if the use of X.121 numbers is required) are indicated in GSM 03.70. NOTE: For card operated stations the ISDN number should be assigned to the holder of the card (personal number). 3.2 Numbering plan requirements In principle, it should be possible for any subscriber of the ISDN or PSTN to call any MS in a GSM PLMN. This implies that ISDN numbers for MSs should comply with the ISDN numbering plan in each country. The ISDN numbers of MSs should be composed in such a way that standard ISDN/PSTN charging can be used for calls to MSs. It should be possible for each administration to develop its own independent numbering plan for MSs. The numbering plan should not limit the possibility for MSs to roam among GSM PLMNs. It should be possible to change the IMSI without changing the ISDN number allocated to a MS and vice versa. In principle, it should be possible for any subscriber of the CSPDN/PSPDN to call any MS in a GSM PLMN. This implies that it may be necessary for an MS to have a X.121 number. 3.3 Structure of MS international PSTN/ISDN number (MSISDN) The MS international ISDN numbers are allocated from the CCITT Recommendation E.164 numbering plan, see also CCITT Recommendation E.213. The MS international ISDN number will then be as shown in figure 2. SIST EN 300 927 V5.4.1:2003

For GSM applications, a National Destination Code is allocated to each GSM PLMN. In some countries more than one NDC may be required for each GSM PLMN. The composition of the MS international ISDN number should be such that it can be used as a global title address in the Signalling Connection Control Part (SCCP) for routing messages to the home location register of the MS. The country code (CC) and the national destination code (NDC) will provide such routing information. If further routing information is required, it should be contained in the first few digits of the subscriber number (SN). A sub-address may be appended to an ISDN number for use in call setup and in supplementary service operations where an ISDN number is required (see CCITT Recommendations E.164, section 11.2 and X.213 annex A). The sub-address is transferred to the terminal equipment denoted by the ISDN number. The maximum length of a sub-address is 20 octets, including one octet to identify the coding scheme for the sub-address (see CCITT Recommendation X.213, annex A). All coding schemes described in CCITT Recommendation X.213, annex A are supported in GSM. 3.4 Mobile Station Roaming Number (MSRN) for PSTN/ISDN routeing The Mobile Station Roaming Number (MSRN) is used to route calls directed to a MS. On request from the Gateway MSC via the HLR it is temporarily allocated to a MS by the VLR with which the MS is registered it addresses the Visited MSC collocated with the assigning VLR. More than one MSRN may be assigned simultaneously to a MS. The MSRN is passed by the HLR to the Gateway MSC for routing calls to the MS. The Mobile Station Roaming Number for PSTN/ISDN routing shall have the same structure as international ISDN numbers in the area in which the roaming number is allocated, i.e.: - the country code of the country in which the visitor location register is located; - the national destination code of the visitor GSM PLMN or numbering area; - a subscriber number with the appropriate structure for that numbering area. The MSRN must not be used for subscriber dialling. It should be noted that the MSRN can be identical to the MSISDN (section 3.3) in certain circumstances. In order to discriminate between subscriber generated access to these numbers and rerouting performed by the network, rerouting or redirection indicators or other signalling means should be used, if available (see GSM 09.03).

The handover number may be reused in the same way as the MSRN. 4 Identification of location areas and base stations 4.1 Composition of the Location Area Identification (LAI) The Location Area Identification shall be composed as shown in figure 3: Location Area IdentificationMCCMNCLAC Figure 3: Structure of Location Area Identification The LAI is composed of the following elements: - Mobile Country Code (MCC) identifies the country in which the GSM PLMN is located. The value of the MCC is the same as the three digit MCC contained in international mobile subscriber identity (IMSI); - Mobile Network Code (MNC) is a code identifying the GSM PLMN in that country. The MNC takes the same value as the two digit MNC contained in IMSI; - Location Area Code (LAC) which is a fixed length code (of 2 octets) identifying a location area within a GSM PLMN. This part of the location area identification can be coded using a full hexadecimal representation except for the following reserved hexadecimal values:
0000, and
FFFE
These reserved values are used in some special cases when no valid LAI exists in the MS (see GSM 04.08 and GSM 11.11). 4.2 Base station identification 4.2.1 Cell Identity (CI) and Cell Global Identification (CGI) The BSS and cell within the BSS is identified within a location area by adding a Cell Identity (CI) to the location area identification, as shown in figure 4. The CI is of fixed length with 2 octets and it can be coded using a full hexadecimal representation. The Cell Global Identification is the concatenation of the Location Area Identification and the Cell Identity. SIST EN 300 927 V5.4.1:2003

BSIC is a 6 bit length code which is structured in the following way. NCCBCCPLMN colour codeBS colour code3 bits3 bits Figure 5: Structure of BSIC In the definition of the NCC, care needs to be taken to ensure that the same NCC is not used in adjacent PLMNs which may use the same BCCH carrier frequencies in neighbouring areas. Therefore, to prevent potential deadlocks, a definition of the NCC appears in annex A. This annex will be reviewed in a co-ordinated manner when a PLMN is created. 4.3 Regional Subscription Zone Identity (RSZI) A PLMN specific regional subscription defines unambiguously for the entire PLMN the regions in which roaming is allowed. It consists of one or more regional subscription zones. The regional subscription zone is identified by Regional Subscription Zone Identity (RSZI). A regional subscription zone identity is composed as shown in figure 6. NDCCCZCZone Code, Two octetsRSZI Figure 6: Structure of Regional Subscription Zone Identity (RSZI) The elements of the regional subscription zone identity are: - the Country Code (CC) which identifies the country in which the GSM PLMN is located; - the National Destination Code (NDC) which identifies the GSM PLMN in that country; - the Zone Code (ZC) which identifies a regional subscription zone as a pattern of allowed and not allowed location areas uniquely within that PLMN. CC and NDC are those of a CCITT E.164 VLR number (see section 5.1) of the PLMN and are coded with a tailing filler, if required. ZC has fixed length of two octets and is coded in full hexadecimal representation. SIST EN 300 927 V5.4.1:2003



ETSI ETSI EN 300 927 V5.4.1 (2000-12)13(GSM 03.03 version 5.4.1 Release 1996)RSZIs including the zone codes are assigned by the VLR operator. The zone code is evaluated in the VLR by information stored in the VLR as a result of administrative action. If a zone code is received by a VLR during updating by the HLR and this zone code is related to that VLR, the VLR shall be able to decide for all its MSC areas and all its location areas whether they are allowed or not allowed. For details of assignment of RSZI and of ZC as subscriber data see GSM 03.08. For selection of RSZI at location updating by comparison with the leading digits of the VLR number and for transfer of ZC from the HLR to VLR see GSM 09.02. 4.4 Location Number A location number is a number which defines a specific location within a GSM PLMN.
