摘要

诸如UMTS和IMT-2000等第3代移动系统的发展应提供一系列灵活的传输特性，以支持移动多媒体应用。这将使许多为ATM和IP开发的宽带多媒体业务能够提供给移动用户。然而，通过无线电接口传输可能导致高错误率和延迟。此外，还需要在切换期间维护用户连接和QoS。将ATM和IP网络中的传输特性与宽带TDMA和CDMA无线接口上的传输特性进行了比较。开发了支持互联、切换和宏观多样性的场景。

Impact of radio interfaces on mobile multimedia services

The development of 3/sup rd/ generation mobile systems, such as UMTS and IMT-2000, should provide a range of flexible transport characteristics to support mobile multimedia applications. This will enable many broadband multimedia services developed for ATM and IP to be offered to mobile users. However transport over the radio interface can result in high error rates and delays. Also there is a requirement to maintain user connections and QoS during handover. The characteristics of transport within ATM and IP networks are compared to transport over wideband TDMA and CDMA radio interfaces. Scenarios are developed for the support of interworking, handover and macro diversity.
