摘要
IP多媒体子系统(IMS)作为融合型计算机网络的最佳代表之一,为多媒体服务提供了一整套标准的体系架构,同时也为各大通信公司提供全新多媒体业务奠定了网络基础,其中视频融合会议是IMS网络的主要应用之一。由于IMS具有接入无关性的重要特点,故可以使各大通信公司在不改变现有网络结构、不投入任何设备成本的条件下,实现现有主流视频会议终端与IMS融合视频会议的对接,满足不同类型用户的接入需求,使得用户能够随时随地、就近就简地接入会议。以国网天津市电力公司信息通信公司为例,设计并提出了多类型视频会议终端接入IMS融合视频会议的实现方案。测试结果表明,针对不同类型终端制定的接入方案能够将各种类型终端平滑接入到新建的IMS多媒体会议系统。
IP Multimedia Subsystem （IMS） ,as one of the best representatives for fusion computer network,provides the multimedia serv- ice with a set of standard architecture and lays the network basis for the communication companies supplying new multimedia services. In the IMS network, the video fusion conference is one of the main applications. Due to the important characteristic of being irrelevant ac- cess, it makes the major communications company achieve the connection between video fusion conferencing and existing mainstream vid- eo conferencing terminals without changing their existing network structure and putting any cost of equipment. Therefore, access needs can be met for the different types of users, so that the users can access the conference easily and conveniently whenever and wherever they want. Taking the information and communications company of Tianjin Electric Power Company as an example, an implemented scheme of multi-type video conference terminal access to IMS fusion video conference is designed. It can be validated by the test schema that differ- ent types of terminals can be smoothly connected to the new-built IMS multimedia conference system.
