Radio Access Network Slicing Based on C/U Plane Separation

摘要

Network slicing achieves many interests from industry and academics due to its flexibility and scalability.In this paper,we present a novel slicing scheme for radio access networks(RANs) based on control/user(C/U) plane separation.Firstly,we divide e NBs into two sub-e NBs called Ce NB and Ue NB,for transmitting control data and user data respectively,thereby facilitating C/U plane separation.Secondly,upon Ce NBs and Ue NBs being virtualized,we develop two RAN slices for control and user plane respectively.Experimental results show the feasibility of the proposed scheme.
