The wireless industry’s battle to acquire new subscribers and retain existing ones increases pressure on communications service providers (CSPs) to create new services while maintaining high availability. Many CSPs are turning to network functions virtualization (NFV) to help handle the increased infrastructure and operations costs of meeting this demand.
A new white paper from Wind River argues that the 4G LTE mobile base station is a good candidate for this ground-breaking technology. [sdnpdf pdf=”https://www.sdxcentral.com/wp-content/uploads/2014/10/Wind-River_CRAN-white-paper.pdf” channel=”Wind-River-WhitePaper-2014-10-27″ title=”“Wireless Network Virtualization: Ensuring Carrier-Grade Availability””] says that while 4G LTE is effective at meeting the increasing bandwidth demands at lower costs than its predecessors, its mobile base station, E-UTRAN Node B (eNB), is underutilized at certain times of the day and has grown in complexity, resulting in higher downtime and field maintenance costs.
Wind River says virtualizing the eNB’s control function can achieve a three-fold improvement in cell downtime and reduction in maintenance costs over the current RAN implementation – as long as the virtualization is built using carrier-grade NFV.
Located at the edge of the radio access network (RAN), eNB provides wireless coverage over a specific cell area by processing control and data information to and from the mobile device and to and from the core network via a backhaul optical network. Under the current RAN implementation, the average utilization of each eNB is often suboptimal because eNBs can’t share loads, so each system must be provisioned adequately to handle peak traffic load.
Cloud-RAN (C-RAN) virtualizes the eNB’s control plane and data plane functions, consolidating them in one or more data centers. By virtualizing the eNB’s control functionality, the C-RAN solution can efficiently share the traffic load and make better use of power, processing, and memory resources while providing efficient redundancy.
Wind River argues such improvements rely on having the right design and implementation of the C-RAN’s underlying NFV solution. The company says its Carrier-Grade Communications Titanium Server provides the fault-management and redundancy options carriers need to successfully attain similar results
