摘　　要：随着移动通信的不断发展,移动网必须提供从低速率的语音服务到高速率的包括视频点播.图像传输等综合业务在内的多媒体服务,与此相适应,移动网必须向宽带化发展.移动终端与基站间的无线接口将采用W-CDMA技术,基站接入ATM骨干网将成为移动网的发展趋势.其关键技术有开放式多速率空中接口和基于无线ATM的传输方案.With the development of mobile communications, mobile communications networks must be able to provide multimedia services from low - rate voice service to highspeed integrated services including VOD, image transmission and so on, therefore mobile communications networks must develop toward broadband networks. The wireless interface between mobile station and the base station will apply W-CDMA technology and the base station get access to ATM backbone network will become the development trends of mobile networks, in which the key techniques include open flexible air interface and transmission scheme based on wireless ATM.
