【摘要】 提供了双连接技术的应用场景,从架构及移动性增强角度对双连接技术进行了分析:架构设计上双连接技术实现了用户平面和控制平面的分离;在用户平面可以通过聚合不同基站的无线资源来提升用户吞吐性能,在控制平面可以通过避免不必要的切换以及将与切换相关的信令通过多个节点传送给终端来增强移动鲁棒性。更多还原

【Abstract】 Deployment scenarios were provided and Dual Connectivity was analyzed from the view of architecture and mobility enhancement: Dual Connectivity achieves the separation of C-Plane and U-Plane;Per-user throughput could be improved by aggregating radio resources from different nodes; besides, mobility robustness could be enhanced by avoiding unnecessary handover and RRC diversity operation.更多还原
