7、ON OF IMT-2000 TERMINALS EXECUTIVE SUMMARY This report deals with the issue of global circulation for IMT-2000 terminal equipment. In this context global circulation is taken to mean the right of users to carry IMT-2000 terminals with them anywhere in the world and use the terminals when transmissio
8、n is authorised. Administrative arrangements necessary to facilitate the global circulation of IMT-2000 terminals are also considered. In this respect the term IMT-2000 is assumed to include all IMT-2000 family members such as UMTS. In addition, consideration is given to multimode terminals where on
9、e of the modes is not an IMT-2000 family member. It has been said that administrative arrangements for circulation may lead to heavier regulation. This must be carefully avoided when developing arrangements for circulation. The circulation arrangements must be aimed at simplijing existing regulation
10、, not increasing it. One of the basic requirements of global circulation is that the terminal involved does not give rise to unacceptable interference in any country where it is taken. One possible means of achieving this is that the terminal does not transmit before it has received a signal from a
11、valid network with which it can communicate (receive-before-transmit principle). However the report recognises that there may be other technical means of achieving the basic requirement. A system for a global marking of IMT-2000 terminals has been considered. The benefit of a marking regime must be
12、balanced against the potential increase in regulatory burden (such as the requirement for multiple markings). For this reason, the subject requires further consideration and further reflection on the working of other regimes. Some possible mechanisms for global circulation are identified in this rep
13、ort and, in particular, the GMPCS MOU and the GSM MOU arrangements are covered in detail. Some other possible arrangements are also considered. However no single solution has been identified to resolve all the global circulation issues for IMT-2000 terminal equipment. A possible means for moving for
14、ward on the issue is identified as the formation of a policy document to be agreed by administrations, which could lead to a phased resolution of the issue. Such a policy document would have to be developed at a global level. STD-CEPT ERC REPORT bO-ENGL 1998 2326424 OOL3521 T73 ERC REPORT 60 Page I
15、REPORT ON GLOBAL CIRCUL. .TION OF IMT-2000 TERMINALS 1 INTRODUCTION IMT-2000 is being developed as a third generation global communication system. A key element in :e success of 1s system is the ability for terminal equipment to circulate world-wide without any hindrance or obstacles. In this respec
16、t users of the terminais will want to carry them throughout the world and use them wherever it is possible to do so. If they are hampered to do so by regulatory barriers, the successful development of IMT-2000 will be impaired. Global circulation will bring clear advantages for the user in terms of
17、global (or near global) availability of the system. There would also be advantages for operators and manufacturers in terms of the global market generated. The global circulation of IMT-2000 terminals is also beneficial for national administrations, since it will allow the national economies to reap
18、 the full benefits of third generation systems and allow the mobile multimedia sector to become an important part of the national market. National administrations throughout the world will play a particularly important role in the development of any global circulation arrangements for IMT-2000 termi
19、nal equipment. This report although generated in Europe is aimed at national administrations throughout the world and may also be of interest to operators and manufacturers. A considerable amount of work has been carried out in Europe on circulation of existing terminal equipment. This report builds
20、 on this experience and develops requirements for global circulation of IMT-2000 terminal equipment. Although the main issue is that of global circulation, one cannot avoid addressing aspects of conformity assessment. In this context the trend in Europe to move away from a priori type approval regim
21、es towards a regime based on manufacturers declaration is relevant. This report deals only with global circulation for IMT-2000 terminal equipment. It emphasises the requirement for equipment to avoid the generation of unacceptable interference. Modem radio technologies, whereby the usage of frequen
22、cies is being controlled by the network (receive-before-transmit concept) achieve this end. The term IMT-2000 is used throughout this report and this is intended to include ali IMT-2000 family members such as UMTS. It has been recognised that global circulation is required for terminal equipment suc
23、h as IMT-2000. Civil authorities all over the world actually does not need to know whether particular IMT-2000 terminals are authorised to circulate globally. Instead, they need to know whether the terminals as a whole are authorised. This becomes especially apparent in the case of a multimode termi
24、nal in which IMT-2000 is only one of the modes, where one of the fellow modes may prevent the whole terminal to enjoy global circulation. The idea of generic global circulation covering all kinds of radio equipment has not been developed in this report, because it was felt that a generic global circ
