LTE与2G/3G核心网融合演进策略研究

Study on the LTE and 2G/3G Core Network Convergence Evolvement Scheme

为保证用户对高速增长数据业务的QoS需求,移动核心网需向EPS演进。重点研究了LTE与WCDMA、GSM核心网的融合演进策略,介绍了融合演进中系统间互操作的功能需求和实现方案,对保护运营商投资、降低运维成本有重要意义。

The mobile core network need evolve to the EPS so that it can guarantee the QoS of data traffic. It studies the convergence evolvement scheme of LTE, WCDMA and GSM, introduces the function requirement and implementation approach for the in- teroperation of different system. It is of great importance to protect the operators＇ investment and reduce the operation cost.
