RAN Slicing-based Handover Scheme in HetNets
Xu Dong, Liqiang Zhao, Hui Zhao, Chengkang Pan · 2018
In this paper, we propose a radio access network (RAN) slicing based handover scheme in heterogeneous networks, which provides users with better QoS of customized services during handover. Firstly, we present a hierarchical control model composed of a global controller and multiple local controllers for the heterogeneous networks, including LTE, WLAN and NR. Secondly, we develop each RAN slice based on control/user plane separation to provide users with customized services. Thirdly, we implement the RAN slicing based handover scheme. Finally, we develop a testbed based on open-source software and the experiment results verify the feasibility of the proposed handover scheme.
