摘要
实时的视频服务是下一代网络(NGN-Next Generation Network)技术研究的热点之一。传统的网络系统具有异构网络之间的数据交换难度大、可拷性差等特点。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,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。介绍了IMS,分析基于IMS架构下需要实现的视频监控业务需求,提出了系统设计方案,并对该方案的系统结构与业务应用进行了探讨。
Real time video surveillance service is one of the hot points in technology research of Next Generation Network.It is fallible and difficult to exchange data among different network in traditional network system.Network architecture based on IMS can fulfill the access requirement of fixed network and the service requirement of future network,and supports multiple service of high layer.So 3GPP IMS represents the development direction of future next generation network.This paper introduces IMS at first.Then we analyze the requirement of video surveillance system based on IMS architecture and submit a solution for the system.Furthermore,we analyze the system architecture and service application in detail.
