简述EPC时代核心网融合技术

LTE-EPC（LongTermEvolution-EvolvedPacketCore）时代已经到来，为适应网络集中化发展的趋势，对LTE／TD／GSM核心网融合组网的探索成为一项重要课题。本文分析了网元融合的必要性及可行性，介绍了基于现网的公共核心网融合方案及性能测试方案，旨在积累公共核心网的建设、运维经验，探索新模式，摸索新规律，为推进通信产业的发展奠定基础。

Research on technical programs of convergence of core networks in EPC Era

With the coming of LTE-EPC era, in order to fit on the centralization trends of network development, the explo- ration on the convergence of LTE, TD and GSM Core Networks has become a meaningful subject. This paper analyzes the necessity and feasibility of the convergence of Core Networks based on the existing network. Furthermore, technical pro- grams and function testing are presented for the accumulation of experiences on networking construction and operation, and the development of new models and new disciplines. The related investigations can promote the development of tele- communications industry of China.
