【摘要】 针对带宽较窄广域IP话音业务报头开销占用较多传输带宽问题,提出了一种IP话音复用技术。采用多路共用协议报头的方式,通过可靠传输协议沟通IP话音报头信息,在发送端语音压缩设备提取每路的话音净荷组成复用分组IP包发送到对端语音压缩设备,接收端语音压缩设备还原分组IP包,发送到终端设备。采用话音复用技术,能够保证话音通话质量,显著提高带宽利用率。更多还原

【Abstract】 This paper puts forward a kind of IP voice packet multiplexing technique aiming to solve the problem of IP voice traffic head’s occupying too much transmission bandwidth in narrow WAN. The principle of the technique is to abstract single voice payload in sending end to form multiplexed IP packets,transmit them to remote voice compressing equipment via reliable transmission protocol transferring IP voice head messages by means of multiplexed protocol packet head,restore IP packets in receiving end,and send them to terminals. This technique has some advantages in improving the utilization of bandwidth greatly and guaranteeing voice quality at the same time.更多还原
