| 摘 要： | 由于SIP协议与H. 323协议之间的非对称性,使软交换信令网关在实现时将不可避免地遇到一些困难。对软交换信令网关中的呼叫建立、信令转换、媒体逻辑信道建立和媒体会话能力交换等一些基本问题进行探讨,并就地址转换、信令转换的一致性等问题提出相应的解决方法,为软交换中信令网关的设计和实现提供了一种思路。

| Abstract: | Because of the asymmetry between SIP protocol and H.323 protocol, there are some difficulties in the course of realizing SGW(Signal Gate Way) in SoftSwitch. Through discussing the following problems such as call setting up, signal converting, media logical channel setting up and media ability exchange, relevant methods about address exchange and the inconsistency of signal interpretation were put forward to realize the SGW in SoftSwitch. |
