CDMA EVDO网络中的QoS保障机制研究

随着3G无线分组网络的飞速发展,基于移动终端的实时多媒体业务需求也日趋广泛.如何保障诸如流媒体直播和可视通话等QoS要求较高的业务,必将成为一个重要的课题.对CDMA EVDO网络中的QoS保障机制进行了初步探讨,阐述了CDMA EVDO网络的QoS实现架构,并以终端MS源发呼叫的QoS协商过程为例,描述了其信令流程.

Research on the QoS Guarantee Mechanism in CDMA EVDO Network

With the rapid development of 3G wireless packet networks,the demand of real-time multimedia services based on mobile terminals are becoming increasingly widespread.How to protect multimedia live broadcasting and video calls service which requires a higher QoS will become an important issue.This article will focus both on QoS guarantee mechanism and its architecture implementation in CDMA EVDO network.Also the QoS negotiation process based on MS terminal and its signaling process will be fully discussed.
