摘　　要：作为标准化程度最高的固定移动核心网的融合目标,IMS网络的规划和解决方案越来越受到业界重视,也因此未来的网间互通必然由目前的以NGN/CS域网间关口局互联和以语音业务互通为主的方式,向以IMS网间互联和以多种业务形式互通的更高级方向发展。从网间互通现状入手,重点论述了Vo LTE等新业务网间互通需求,详细分析了不同运营商网络网间互通原则与需求,并将网间互通现状与核心网融合演进要求结合起来,给出了网间互通关口局网元融合演进思路和分阶段部署建议。IMS network, as the highest level of standardization of the fixed and mobile convergence core network target program, its planning and solutions get more and more attention of operators. The future of interworking of networks is developed to IMS network interworking and various business interworking from NGN/NC domain gateway interworking and voice service interworking. Beginning with the current situation of networks interworking, it discusses the requirements of Vo LTE network interworking, analyzes the interworking principles and requirements on different operators＇ network, gives network interworking gateway element convergence evolution consideration and suggestions on deployment on phase.
