| 摘 要： | 软交换是下一代网络中的核心技术,SIP协议在软交换中起着十分重要的作用。但SIP协议的NAT穿越一直影响着NGN业务的发展。文章介绍了SBC方案,并在其基础上提出B2BSBC的私网穿越方案,实现了只收不发、收发端口互异等特殊终端在不同私网间的通信。

| Abstract: | Softswitch is the core technology of NGN(Next Generation Network).And SIP(Session Initiation Protocol) plays an important role in softswitch.But the NAT(Network Address Translator) traversal for SIP has been an operational impact on the development of NGN service.In this paper,SBC(Session Border Controller) is introduced to solve this problem,and a solution is proposed for SIP traversal NAT based on SBC,implement the communication between two special SIP phones which only receive or do not use the same port to send /receive RTP packets. |
