摘要/Abstract

摘要： 对基于主机媒体流（HMP)这一新技术的控制与呼叫进行了探索性的研究。提出采用SIP和RCT协议协同完成HMP的通信控制的模式，并在该模式下着重解决了HMP下双音多频（DTMF)信令的正确识别问题，以及缩短DTMF传送时间的探索和具体方法。

关键词: HMP, 呼叫信令, 呼叫控制, 双音多频

Abstract: The communication signal system and signal control of Host Media Processing (HMP) were studied. One new model of communication using HMP, which combined SIP and MS RCT as communication protocols, was proposed. The procedure of improving the identification of Dual Tone Multi Frequency (DTMF) under this model was provided, and the methods of reducing the transportation time of signal were informed.

Key words: Host Media Processing, Call Signal System, Call Control, Dual Tone Multi Frequency
