异构融合网络体系技术

[摘要] 将WLAN和蜂窝网络进行融合形成了异构融合网络体系，研究并分析了该体系的若干关键技术。该异构融合网络体系能够有效实现用户无感知接入WLAN网络，降低终端的功耗，尽可能地利用现有的网络资源，充分体现用户意愿，并提高用户业务体验，另外还能够优化运营商网络资源的使用、管理和控制，为运营商网络部署和运营提供重要的参考价值。

[Abstract] In this paper, we describe the integration of two kinds of heterogeneous networks: WLAN and cellular. We analyze the key technology in a heterogeneous converged network system, which realizes non-perceptive access WLAN, saves terminal battery, efficiently uses existing network resources, and improves user experience. A heterogeneous converged network system also can better use and manage operator network resources. This paper also is a reference for operators deploying networks for the future.
