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.
