摘要
通过对SIP协议的分析和研究,设计一个基于SIP的软交换的解决方案,用以实现在集群通信系统中基站间的联网交换,并且进行相应的SIP用户代理、SIP代理服务器的开发、NAT穿透问题的解决,在公安专网环境下对该系统进行了验证。
Through the analysis and research on the SIP protocol,this paper proposes a solution based on SIP Softswitch.It can be used to implement the networking exchange between the base stations in the trunking system,to develop corresponding SIP agent and SIP proxy server,and to solve the NAT penetration problems.The system has been tested in the public security special network.
