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.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.
