The development trend in telecommunications is driven by user service requirements asking for access to a diversified range of personalised set of services to anyone, anywhere, anytime but not at any price. Borders between telecommunications, information technology and entertainment services are disappearing and users can combine service offerings from various operators. Deregulated world-wide market and rapid introduction of mobile services of the second generation, specifically GSM, has lead to the conclusion that one "ultimate mobile solution ", one radio access network and one single core network standardised to a very detailed level is not realistic. Flexibility and opportunities of choice within mobile communications are avaiIable to a large extent already today. The choice is available for users, service operators, network operators and manufacturers. Consequently UMTS development takes into account the opportunity of the choice and the multiplicity of futed and mobile telecommunication networks and services. Several of these systems can evolve towards UMTS with their own targets and pace. Such facts are influencing the current standardisation process at both national, regional.
The evolution path of 3G/UMTS as well as its some aspects give us an overall general picture of 3G really is a necessary step after all. Technically speaking, 3G is an advancement over present GSM services, able to offer much in terms of quality multimedia services. However, for users of mobile telephony, it is not so important to them what sort of technology makes communication possible. It is the type of service and the quality of the service that they obtain that is of more importance to them. What users want are services that make things more convenient and accessible. GSM is predominantly a voice service technology and this was the most important service to offer at the time when GSM was introduced because mobile telephones should offer just that: Telephone services but with mobility. However, it has since evolved to encompass some data services such as SMS and some internet access capability. Further enhancements allowed even faster access to the Internet and to other services. With 3G and UMTS, even more services can be introduced to the public.
In my country, Vietnam, we have six mobile service providers, yet none of them offer 3G services. Two mobile technologies have been using there. A half of providers uses GSM technology. And the rest uses cdma-1x. The quality service of cdma-1x in my country is not good. The calls sometimes drop or speech is delayed. Even the strategists of cdma-1x companies created a lot of advertisement campaigns or sale promotion, they can not attract the customers who had used GSM services. GSM providers gain over 70 percent of mobile market. 3G technology has just been setting up the fundamental platform in Vietnam mobile service market. For example, ZTE Corporation, China's largest listed telecommunications manufactures and leading wireless solutions provider, is to install Vietnam's first 3G network in Ho Chi Minh city. ZTE will provide a network based on the Corporation's 450 MHz EV-DO (EVolution - Data Optimized or EVolution - Data Only) technology, which will bring 3G technology to the seven million inhabitants of Vietnam's largest city. I hope that Vietnames will soon have chance to use the 3G services in the near future.
