摘要：Traditional mobile networks become unable to cope with the huge use of wireless internet services and the growth of data traffic. The solution to this challenges can be found in a novel mobile network architecture called Cloud Radio Access Network (C-RAN) that is expected to be the essential part of the next fifth generation of mobile networks (5G). The C-RAN system will achieve increased significant cost and address number of challenges for mobile operators in terms of optimization, configuration, network controllability and software management. This paper will present and give an overview of C-RAN including system architecture and key techniques. It shows challenges and benefits of this technology. The paper presents also fronthhaul network requirements that must be achieved by the CPRI technology and transport options for C-RAN. User data plane, CPRI planes control, planes data Management and CPRI frame synchronization are also discussed.
