移动软交换IP承载信令及语音带宽计算研究

摘要

It briefly describes the difference between mobile soft switch signaling and voice over IP technology and the traditional TDM bearer. Based on the R4 network architecture, it expounds the basic concept of H.248, BICC, MAP, CAP, ISUP and BSSAP, and the protocol stack and bandwidth calculation, as wel as the basic concept of Nb interface and the protocol stack and bandwidth calculation.%　　简要说明了移动软交换信令、语音IP化后与传统TDM承载的不同；在给出R4网络架构的基础上，详细阐述了H.248、BICC、MAP、CAP、ISUP、BSSAP信令的基本概念、协议栈、带宽计算方法和Nb接口的基本概念、协议栈、带宽计算方法.
