基于IP架構(gòu)的cdma2000 1x系統(tǒng)TrFO特性的設(shè)計(jì)與實(shí)現(xiàn)

摘要：本文介紹了基于IP架構(gòu)的分組語音核心網(wǎng)的TrFO特性，并結(jié)合自行開發(fā)的cdma2000 1x系統(tǒng)，討論了TrFO特性在基于IP架構(gòu)的cdma2000 1x移動(dòng)通信中的具體實(shí)現(xiàn)方案，詳細(xì)討論了多種聲碼器的靈活配置策略，并對(duì)各種策略進(jìn)行了模擬比較，模擬結(jié)果對(duì)實(shí)際工程實(shí)現(xiàn)具有重要意義。

Ａｂｓｔｒａｃｔ：The TrFO characteristic in the IP-based packet speech core network(CN) is introduced. Taking the self-developed system as an example, a scheme for implementing TrFO in the IP-based cdma2000 1x system is discussed, strategies of multi-vocoder unbended configuration are explained and simulated.The results are very important for the practical work.
