RFCI用来指示相应的RAB子流集合, 每种组合对应不同的AMR速率,如, 12.2, 7.95, 4.95等, 可能刚好RFCI=0对应了12.2K.

以下是来自网络一哥们的注释:
=============================================================
“下面是一段AMR2语音流的raw data (R4 IP bearer, Nb interface)
0(type=0)3(frameNumb=3) 00(FQC=0,RFCI=0) 9d 0a(CRC)(Here RFCI=0 means 12.2k)
48 f9 1f 96 66 79 e1 e0 01 e7 8a f0 00 00 00 c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00(Here is AMR2 raw data,totoal 248bits)
注释是我自己加的,可以看看”
=============================================================
说实话,我没看到他的注释:(Here RFCI=0 means 12.2k) ?怎么来的?
