基于IMS的网络架构支持固定网络接入需求和未来网络的各种业务需求,有利于实现未来固定、移动网络在核心业务控制层的共享和融合,并提供对高层多种业务的支持,已经成为下一代网络的发展方向。本文介绍了北电网络基于IMS的NGN解决方案的网络结构和核心部件,并对该方案的组网能力与业务应用进行了分析。
Network architecture based on IMS can fulfill the access requirement of fixed network and the service requirement of future network, which plays a vital role in the fixed mobile convergence at core service control layer and supports multiple service of high layer, so 3GPP IMS represents the development direction of future next generation network. This paper introduces the network structure and core components of Nortel networks NGN solution. Furthermore, we analyze the interworking capability and service application of succession IMS in detail.
