通信技术不断发展,网络技术不断演进,便于多方沟通和交流的电话会议系统得到了越来越广泛的应用。传统的PSTN(公共交换电话网)网络逐步向NGN网络演进。由于软交换网络组网灵活、业务丰富,所以基于软交换网络的会议系统成为研究的热点。介绍了这种会议系统涉及的各种技术,并给出了系统的网络模型和软件结构。
With the continuous development of communication technology and the ever-evolving network technology, teleconferencing systems that facilitate multi-party communication and exchange have been more widely used. The traditional PSTN (Public Switched Telephone Network) network gradually evolves to the NGN network. As the softswitch network flexible networking, business-rich, so based on softswitch network conference system has become a hot research. The various technologies involved in this conferencing system are introduced, and the system network model and software structure are given.
