Key Technologies Towards Next Generation of Network
Yang Fang · Beijing Youdian Xueyuan xuebao · 2003
Next generation of network(NGN) is similar to many aspects of intelligent network(IN) principles, but it works better than IN due to different implementation technologies. Through comparisons between the architectures and goals of NGN and IN, five major drawbacks appeared in current IN technology are analyzed. Then several key technologies on open API, service generation methodology and network evolution that need to be concerned and further investigated for NGN are proposed, especially regarding how to inherit the invested IN to build NGN architecture.
