Foreword This ETSI Guide (EG) has been produced by ETSI Technical Committee Services and Protocols for Advanced Networks (SP

12、AN). I n t rod uct ion The present document provides information on the TETRA ITSI. The ITSI is similar in structure to ITU-T Recommendation E.212 4 IMSI identity. In addition to providing background on the similarities and differences between these two identities, the present document also describe

13、s each of the individual fields of the TETRA ITSI. In certain circumstances operators may have to relate these two resources together. Given the management of the individual elements of the ITSI (the TETRA Mobile Country Code, the TETRA Mobile Network Code and the Short Subscriber Identity), the pre

14、sent document describes how an approach taken by a National TETRA Numbering Administrator, responsible for managing the TETRA MNC, might assist an operator in the use of both resources. TETRA Mobile Country Codes (T)MCC are currently administered by the TETRA Memorandum of Understanding (MOU) Group,

15、 an industry organisation, which has aligned the digital value of the (T) MCC with the ITU-T Recommendation E.212 4 MCC. An issue has been raised as to how countries know that these codes are formallyAegally assigned to the country allocated. Discussions are under way to move the administration of (

16、T) MCC resources to the ITU-TSB. ETSI 5 ETSI EG 202 118 VI .I .I (2003-05) 1 Scope The present document provides guidance on the allocation and management of the country code and network code parts of the Individual TETRA Subscriber Identity (ITSI) used in TETRA. It applies to all TETRA networks irr

17、espective of their interconnection arrangements. It includes guidance on the effect of dual mode operations with the GSM family of systems on the allocation of TETRA codes. The present document is intended primarily for use by National Numbering Plan Administrator and National TETRA Numbering Admini

18、strator (NTNA) and network operators. TR 102 300-5 2 gives further information about the implementation of the ITSI and the various dialling arrangements that may be used. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the p

26、e TETRA ITS1 An Individual TETRA Subscriber Identity (ITSI) has 3 component parts, a TETRA Mobile Country Code (T)MCC), TETRA Mobile Network Code (T)MNC), and a network specific short subscriber identity (SSI) which have fixed number lengths. The ITSI structure and format are as shown in figure 1. N

27、OTE: In the present document the TETRA MCC and MNC are called (T)MCC and (T)MNC to distinguish them from the ITU-T Recommendation E.212 4 MCC and MNC. The TETRA main standards use the terms MCC and MNC because they assume the TETRA context. 4 decimal digits I I 8 decimal digits ITSI Maximum of 15 de

Mobiles, however, are normally designed to be capable of displaying the identity in decimal form for the human user. The subsequent

29、text of the present document refers to the decimal form as read by a human. The structure an ITSI in decimal form is quite similar to that of the ITU-T Recommendation E.212 4 IMSI, used by public land mobile networks e.g. the GSM family of networks, but it is a separate numbering scheme.

31、) TETRA Mobile Country Codes (T)MCC) are currently administered by the TETRA Memorandum of Understanding (MOU) Group, which is an industry organisation. EN 300 392-1 i specified initially that the (T)MCC values should copy the values allocated in ITU-T Recommendation X. 121 5, but, because ITU-T Rec

32、ommendation X.121 5 relates to an older and different technology, the MOU is currently copying the values allocated under ITU-T Recommendation E.212 4 for the IMSI. No values other than those allocated under ITU-T Recommendation E.212 4 have been allocated by the MOU. NOTE: The current intention is

33、to update the TETRA standards to say that assigned E.212 MCCs will be the basis when (T)MCCs will be assigned and administered in the future by the ITU-TSB. Because the TETRA MOU is not an intergovernmental body, its allocations are not necessarily recognised by all National Regulatory Authorities (

34、NRA). Discussions are under way to transfer the administration of (T)MCC resources to the ITU-TSB to put the scheme fully under the control of national regulatory authorities and to give international recognition to the TETRA numbering arrangements. 6 Allocation and administration of TETRA Mobile Ne

35、twork Codes( (T) M N C) The administration of TETRA Mobile Network Codes is a national matter. In practice they may be administered by the National Numbering Plan Administrator, under the NRA, or by the National TETRA Numbering Administrator if other than the National Numbering Plan Administrator. T

36、he administrator is called in the present document the National TETRA Numbering Administrator. Where the administrator is not the NRA the NTNA may wish to obtain guidance from the national numbering plan administrator on best practice for the administration of the codes. NOTE: ITU-T Recommendation E

37、.190 3 includes some general principles that may be followed. ETSI 8 ETSI EG 202 118 VI .I .I (2003-05) 7 Guidance on allocating TETRA MNCs for dual mode operation with systems that use ITU-T Recommendation E.212 MNCs 7.1 Bac kg rou nd (T)MNCs are in principle independent of other identity schemes a

38、nd so may be allocated in whatever manner the NTNA decides. However there is a possibility that operators may wish to run dual mode systems with technology that uses ITU-T Recommendation E.212 4 IMSIs (e.g. GSM and UMTS/IMT-2000), and this clause gives guidance on how the numbering systems relate to

39、 each other in dual mode operation. In dual mode operation, a dual mode terminal will appear to a TETRA network (home or visited) as a normal TETRA terminal, but will appear to a visited GSM network as a normal GSM terminal. It is assumed that no modifications will be made to the GSM networks to fac

40、ilitate dual mode operation with TETRA. The home TETRA networks that supports dual mode will have to appear to visited GSM networks as a GSM network or at least a mobile virtual network. This involves operating a GSM style Home Location Register (HLR) and supporting GSM authentication and charging a

41、rrangements. There are two options for the numbering of the mobile terminal: - To have an IMSI value for use with GSM different from the ITSI value for use with TETRA, which would require the TETRA operator to translate from one to the other. To use a common decimal value of IMSI and ITSI for use wi

42、th both systems, which requires a common value of E.212 MNC and (T)MNC and is known as alignment. - The choice of the options is unlikely to affect the design of the mobile terminals and their SIMS since manufacturers would be likely to design terminals to accommodate separate values. However there

43、is a possibility that the use of a common value could provide some cost savings for the home TETRA operator who is supporting dual mode. In order to assist the NTNA decision whether or not such savings exist, and therefore whether the aligned approach can be justified, evidence shall be provided by

44、the operators concerned. 7.2 Allocations of (T)MNC in relation to E.212 MNC The National TETRA Numbering Administrator may wish to facilitate the use of dual mode operation with a common value of IMSI and ITSI. Since the values of the E.212 MCCs and the (T)MCCs have the same numerical value, and sin

45、ce the subscriber number is an internal matter for the operator, the issue focuses on achieving a common value of the network code. If the National TETRA Numbering Administrator does not make these arrangements, the TETRA operators will have to translate numbers if they provide dual mode operation.

46、The following applies only where the National TETRA Numbering Administrator wishes to facilitate dual mode operation with a common value of IMSI and ITSI. Where a common value is not intended, the schemes are totally separate and any (T)MNC value may be allocated without regard to the assigned E.212

47、 MNC value. ETSI 9 ETSI EG 202 118 VI .I .I (2003-05) Figure 3 shows the ITU-T Recommendation E.212 4 and TETRA network code numbering spaces aligned with each other.

48、ame as E.212 MNCs For TETRA where 3 digit E.212 MNCs are used +Dual Mode Figure 3: ITU-T Recommendation E.212 4 and TETRA MNC values where administrators support alignment NOTE: To ensure consistency with those countries that use 3 digit E.212 MNCs, the TETRA range O100 to 0999 should not be used. I

49、TU-T Recommendation E.212 4 values have a range from O0 to 99, whereas (T)MNC values have a range from O000 to 9999. Since the ranges overlap only for the values O0 to 99, TETRA allocations for single mode operation should be limited to the range 1 O00 to 9 999. This approach takes into account the possible use of TETRA MNCs in the range O100 to 0999 in those countries that have 3 digit E.212 MNCs where the NTNA has chosen the aligned approach. Where an operators wishes to introduce dual mode operation, the operators should first obtain
