摘要
针对SIP软交换系统提出了在同一个会话中点到点终端对话的状态可达性模型。根据SIP及SIP扩展协议,并结合stateless和stateful的模式,研究SIP终端间三方通话时的对话状态可达性模型,通过应答前传送来检证三方通话的对话状态可达性模型。
In this paper, aiming at SIP Softswitch system, proposes reachability model of point - to - point ter- minal dialog in the same session. According to SIP and its extended protocol, combining to stateless mode and stateful mode, researching on dialog reachability model while the three - way calling between the SIP terminals, Through the Unattended Transfer and Attended Transfer to validate dialog reachability model while the three -way calling.
