摘 要:在世纪之交,电信的焦点也相应地从传统的面向有线电话的业务和基础设施变成了面向数据的业务,从单一的网络变成了多种网络,从非智能设备变成了智能设备,如PDA和移动计算机。 Internet的WWW和广域无线网络(比如GSM),以及局域无线通信系统都导致了这一领域的改变。在这些领域,每年的市场表现都被低估了。现在是考虑移动Internet和UC的未来、技术和市场的时候了。 在ITU的IMT-2000[2]框架里的UMTS业务的概念将是过渡到下一代移动网络的技术步骤,它通过将Internet协议运用到移动业务控制和端到端的应用而使UC变得容易。它的演进会在本文中描述。At the threshold of the new millenium, the telecommunication's focus changed considerably:from traditional wireline telephony oriented services and infrastructures to data based services, fromhomogeneous to heterogeneous networks, from non-intelligent devices to smart handhelds, PDAs andMobile Computers. The Internet with its world-wide web as well as wide area wireless networks such asGSM and mobile wireless communications in the local areas contributed to the dramatic changes in thisfield. The forecasts of both sectors' markets were underestimated every year. It is now time to think abouttheir future, their technologies and their markets' convergence - about the mobile Internet and aboutubiquitous computing (UC). Universal Mobile Telecommunication System (UMTS) - the third generationmobile service concept in the International Telecommunication Union (ITU) framework of IMT-2000 [2]will be a technology step to next generation mobile networks facilitating UC by applying Internet protocolsfor mobile services control and for end-to-end applications. Its evolution will be described in this paper.
