摘要：

Heterogeneous　cloud　RANs　have　been　proposed　as　a　cost-effective　solution　to　promote　wireless　network　coverage　and　data　rate.　However,　many　urgent　issues,　such　as　cross-tier　interference　avoidance,　converged　network　management　and　the　fulfillment　of　consistent　experience　quality,　still　need　to　be　tackled.　SDN　and　virtualization　empower　the　high　efficiency　management　of　networks,　based　on　which,　a　QoE　driven　RAN　architecture　(QvHran)　is　proposed.　QvHran　aims　at　providing　a　new　organization　and　management　norm　to　perform　consistent　management　for　future　H-CRANS.　We　design　the　QvHran　architecture　from　both　management　and　deployment　aspect,　and　also　study　the　relationships　between　them.　Based　on　the　proposed　architecture,　its　key　supporting　technologies　are　also　presented,　include　heterogeneous　resource　virtualization,　network　situation　awareness,　and　elastic　allocation　of　virtual　resources.　Lastly,　a　simulation　is　given　to　demonstrate　the　elastic　resource　allocation　in　QvHran.　Simulation　results　has　shown　that　RAN　performance　can　be　improved　a　lot　in　QvHran.　©　Springer　Nature　Singapore　Pte　Ltd.　2017.
