主　　题：Radio access network mobility management edge cloud computing X2-based handover 

摘      要：The installation of small cells in a 5G network extends the maximum coverage and provides high ***,this approach increases the handover overhead in the Core Network(CN)due to frequent *** variation of user density and movement inside a region of small cells also increases the handover overhead in ***,the present 5G system cannot reduce the handover overhead in CN under such circumstances because it relies on a traditionally rigid and complex hierarchical sequence for a handover ***,Not Only Stack(NO Stack)architecture has been introduced for Radio Access Network(RAN)to reduce the signaling during *** paper proposes a system based on NO Stack architecture and solves the aforementioned problem by adding a dedicated local mobility controller to the edge cloud for each *** dedicated cluster controller manages the user mobility locally inside a cluster and also maintains the forwarding data of a mobile user *** reduce the latency for X2-based handover requests,an edge cloud infrastructure has been also developed to provide high-computing for dedicated controllers at the edge of a cellular *** proposed system is also compared with the traditional 3GPP architecture and other works in the context of overhead and delay caused by X2-based handover requests during user *** results show that the inclusion of a dedicated local controller for small clusters together with the implementation of NO Stack framework reduces the significant amount of overhead of X2-based handover requests at CN.
