摘要

多网络长期共存是各电信运营商面临的普遍现象，鉴于目前各网络独立运营引入的多网间互操作复杂、联合运营效率不高的问题，如何实现高效的多网融合以提高网络运营效率和用户体验成为移动通信研究中的一个重要课题，并具有广泛的应用前景。面向5G，其研究与网络架构的设计是相辅相成的，在对多网融合现状及问题进行分析的基础上，讨论了多网融合涉及的关键技术需求，并给出面向5G的逻辑架构示例，分析了相关的设计原理，同时进一步给出了用户/核心网透明的多网统一接入和无缝的移动性管理解决方案，缩短了网络间互操作路径，降低了互操作复杂度，提高了网络运营效率和用户体验。

Abstract

It is common to operate more than one RAT of operators，who are confronted with complicated cooperation among multiple RATs，and relative low multi-RAT cooperating efficiency. How to facilitate efficient multi-RAT coordination to improve cooperation efficiency and user experience has become an important research topic with broad application prospects. The research supplements each other with 5G network architecture design. On the basis of analyzing background and research status，key technologies were addressed. A paradigm of logical architecture was given and discussed from multi-RAT point of view. And further solutions of user/core agnostic multi-RAT unified access and seamless mobility were given to shorten cooperation path，reduce complexity of cooperation，and improve cooperating efficiency as well as user experience.
