摘　　要：在分析SIP协议、SIIT和NAT-PT分类的基础上,提出了在不改动终端和原有设备的基础上将DNS-ALG与NAPT-PT相集成的方案,其不对原来的协议栈进行扩展,UA可以直接利用现有的协议栈,只需简单的配置就可实现SIP在异类网间的通信。且通过上层协议映射使大量的IPv6主机使用同一个IPv4地址,节省了IPv4地址资源。最后对本方案进行了测试。After analyzing SIP and two methods of translating between IPv4 and IPv6 and types of NAT-PT,a solution is proposed to integrated between the DNS-ALG and NAPT-PT,which not change the original terminal equipment and the environment,UA can directly use of existing resources to achieve SIP stack SIP communications.At the same time through high protocol implement mass of IPv6 address map to a IPv4 address.At last the solution is tested.
