This paper proposes a method to reduce network cost and increase efficiency based on C-RAN target network.By building C-RAN target network

reconstruct the fixed connection relationship between remote radio frequency unit and baseband processing unit

centralize and cloud BBU

virtualization and collaboration technologies are used to realize the dynamic sharing of resources and promote the simplification and efficiency of network architecture

so as to improve the utilization of spectrum

reduce cost and increase efficiency

enhance the flexibility of operation and improve profitability.
