摘　　要：电路交换网络的线路利用率低、新业务开展困难等缺点,促使人们探索新技术。作为下一代网络的主流技术之一,IMS很好地解决了异构网络的融合、业务的融合。文中提出了传统终端直接接入IMS网络、PSTN/ISDN网络与IMS网络互连互通的实现方案。The low utilization ration of line and difficult developmentof new srevices for circuit services for circuit switch impels the people to explore the new methods and new technologies. IMS is one of the next generation network technologies, which solves well the aggregation of heterogeneous networks and the fusion of different services. In this paper, the scheme is proposed, in which the traditionary terminal directly gets access to the IMS network and the IMS network interconnects with the PSTN/ISDN network.
