摘要 To employ the network resources more effectively and fl exibly,cloud radio access network(C-RAN) adopts centralized network construction and management. Since the new network characteristics,the self-healing is reliable distinguish compared with previous studies. This paper drives a solution for selfhealing based on cooperative transmission and power adjustment under C-RAN self-healing management architecture. This compensation model with the aim to maximize the number of connected UEs and optimize power regulation is solved by Benders' decomposition algorithm. And through the simulation,this paper verifies the speediness and effectiveness of this scheme.
