3G手机与NGN通信设备间的多媒体互通设计

Design for Communication Between 3G Mobile Phone and NGN Terminal

随着移动通信和NGN网络的发展,实现NGN终端和3G手机之间的多媒体互通成为一个必须解决的问题。3G网络中的无线多媒体通信协议是3G-324M,而NGN分组网络中的多媒体通信标准则是H.323/SIP,支持两种设备互通必须解决不同层面的问题。为此,提出了基于软交换技术实现3G无线多媒体与NGN网络互连的方案,并深入探讨了方案的实现机制。

With the development of wireless communication and NGN, the communication between 3G mobile phone and NGN terminal becomes a necessary problem to resolve. The multimedia communication protocol for 3G is 3G-324M; however, the protocol for NGN is H. 323/SIP. The scheme based on soft switch to implement the multimedia communication between 3G and NGN is presented and its implement mechanism is discussed in depth.
