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 eNBs into two sub-eNBs called CeNB and UeNB,for transmitting control data and user data respectively,thereby facilitating C/U plane separation.Secondly,upon CeNBs and UeNBs being virtualized,we develop two RAN slices for control and user plane respectively.Experimental results show the feasibility of the proposed scheme.
