Small Cell Virtualization Champions Presentation Dallas Nov 2015 Mark Grayson (Cisco) & Shi Xiaohui (CMCC)

VCHTENPHY

Virtualization

Mobile Networking Mega Trends

Indoor coverage, higher frequencies, shorter ranges, increased co-ordination

Not just Mobile Broadband, but APIs and agility to support verticals and IoT value chains

Twin focus on CAPEX/asset utilization as well as OPEX/automation

Base Station Densification

Broader set of Use Cases NFV and SDN

Topic SCF-106 Findings

What are the real business benefits of virtualization in the RAN?

Identified centralization benefits, transport costs & MANO/Automation elastic scaling capabilities

Are current small cell architectures well suited to virtualization?

Yes - FAPI MAC/PHY decomposition well suited to provide virtualization baseline

Can virtualization deliver a phased roadmap, e.g., aligned with longer-term 5G directions?

Yes - Flexible virtualization over non-ideal transport now emerging as core 5G requirements

How do we ensure virtualization supports innovation across a multi-vendor ecosystem?

SCF’s nFAPI work stream set to accelerate multi-vendor PNF/VNF interoperability
