With rising requirements for ultra-high-speed mobile networking coming in parallel with the auspicious 5G cellular networks, the operators, in order to react to this growth, have to adapt their infrastructures to the explosive increase in traffic by users, connected devices, mobile broadband and other networked services. How to modify the existing Radio Access Network (RAN) infrastructures to enable new serviceability and a simplified deployment approach is exactly the trial for these operators. This will cost them dearly as deployment and management of distributed base stations would become more complex. C-RAN (Cloud-RAN), or Centralized-RAN, is hence introduced and anticipated as the optimal solution. It can realize RAN advantages on the base of cloud-native architecture by running selected 5G RAN network functions through Commercial off-the-shelf (COTS) hardware platforms, efficiently lowering TCO (total cost of ownership) while reducing latency, enhancing capacity and cellular network infrastructure coverage.
The “C” in C-RAN also stands for the four main characteristics of the C-RAN system – Clean, Centralized processing, Collaboration and a real-time Cloud Radio Access Network, which are well represented by the following components that contribute to a successful C-RAN implementation:
- Right COTS Hardware
Successful C-RAN implementation must choose the correct hardware platform and the virtualization environment in the first place. Since Distributed Units (DU) come with higher processing and latency requirements, the hardware accelerator is a prerequisite for a Commercial-off-the-shelf server.
- Centralization & Cloud-native Architecture
As the C denotes both Centralization and Cloud – two separate but highly related terms of this new architecture, the adoption of NFV (Network Function Virtualization) and Cloud computing orchestrations in RAN infrastructures allows operators to aggregate computing resources, service scalability, cell layers and wireless standard compatibility while disaggregating the RAN functionality through the RAN software and hardware that possess the potential of implementing innovative technologies and service deployment at the edge facilitation.
- Collaboration of Services
Along with 5G era comes the arrival of Cloud-RAN, edge computing, network slicing, the software-defined radio (SDR) and networking technologies, all of which are evolving to deliver software-defined everything through the Cloud, hence arises the need for the resources to be pooled and dynamically allocated while processes being automated over application programming interfaces, network functions being provided through service management and orchestration (SMO).
- RAN Programmability
An essential evolution of C-RAN architecture is a Virtualized-RAN— RAN programmability that ensures software definability and adjustability, making it possible to deploy non-RAN functions in the virtualized system using programmable software layers, further reducing CapEx and OpEx as well as creating more business opportunities.
