cdma2000系统向3G网络演进有一条技术路线是只支持高速分组数据业务的EV-DO。目前,EV-DO系统在空中接口的框架已经基本建立起来,存在着两个不同的实现版本,即Release0和ReleaseA。文章将就这两个标准版本之间的区别展开分析,为未来的网络建设和业务发展提出一些合理化的建议。
cdma2000 system to 3G network evolution has a technical route is only supports high-speed packet data services EV-DO. At present, the framework of the air interface in the EV-DO system has been basically established. There are two different implementation versions, Release0 and ReleaseA. The article will analyze the differences between these two standard editions and put forward some rationalized suggestions for future network construction and business development.
