摘要
本文以四网协同组网场景下的互操作方案为切入点,通过核心网的深度融合,从实际业务连续性保障的需求出发,探讨分析了终端在2G/3G/LTE和WLAN之间的无缝漫游及互操作流程,实现业务连续性体验,往四网协同发展的目标演进。
This article discusses the architecture model and characters of the 2G/3G/LTE/WLAN network, and describes the non-seamless off-load solution of the I-WLAN network and SAE network. It solves the problem that UE can not keep the packet data service between 2G/3G/LTE and WLAN network, providing smooth evolution to seamless WLAN offioad using I-WLAN and SAE.
