Separate Control & Data Planes Separate Service Logic From HW (Still no Northbound Interface) Emergence of Intelligent Networking (SS7/AIN) 1982 Mid 80’s Mid 90’s+ Mid 00’s-Today First Wave Of Telco Virtualization The Second Wave The Third & Not The Last? STEP1 : Separate service logic from Switching HW RESULT: SUCCESS! Opened up whole new ecosystem Emergence of Soft Switch Technology (MGCP) STEP2: Separate control & data planes (commodity HW!) RESULT: MIXED! HW not ready, Poor North I/F Convergence of Telecom & IP Purpose built HW remains (e.g. MG,SBC) (MEGACO, SIP) IPRubicon Networks Will Always Converge To Most Efficient Available Means Of Implementation

Also along with SDN goal is to open up a whole new application ecosystem, take what AIN did 30 years ago to a next level… Value Proposition Reduced CAPEX/OPEX, Energy, TTM, Truck Rolls, Improved flexibility, Faster testing of new Apps, Open market to new software suppliers… Use Cases (Network Functions) Switching Elements, Mobile Network Nodes, Virtualized Home, Traffic Analysis, IMS/SBC, AAA/Policy, CDN/Caches, Load Balancers, Security Functions, etc. Current Status Nearer beginning of hype cycle than end but inevitable for all reasons discussed, ETIS ISG (100+ strong), No standard northbound interface, Endpoints out of scope Orchestration will be key… Key Enabler

Tomorrow – Next Generation Networks (5G) Some of the central requirements emerging in the 5G discussion: • Ultra broadband; 1000x performance improvement on LTE 2010 • Support for the asynchronous behaviour of the 50B IoT Devices • Extreme low latency (1ms) to support emerging tactile internet • 90% energy/power reduction on a per functional service basis • Move to rapid service creation from >90-hours to <90-minutes And perhaps most importantly a re-architecting of the value chain • End of network neutrality and rise of the Network as a Service • OTTs need access to data & operators need to monetize assets status, QoS, E2E service definition, subscriber id, device type, access type… SDN/NFV will provide the same foundation for both evolving & next gen. networks that SS7/AIN did for previous generations
  6. 6. 6 © 2014 InterDigital, Inc. All rights reserved. To Meet Challenge – RAN Will Get Much More Complex Key emerging technologies: • Increased cell densification (small cells) to meet future requirements • Introduction of mmW hotspot to deliver Gbps over limited areas • Smart Spectrum sharing & aggregation (Spectrum virtualization?) • Advanced D2D scenarios that blur the line between Network and Device (Device virtualization?) • Deep, just in time edge caching to support extreme low latency targets • Self organizing, joint access backhaul, full mesh roadmap finally realized • And yes a new waveform at some point because simply OFDM does not do a lot of this stuff particularly well Will Introduce New Challenges & Complexity For NFV Orchestration Mass deployment of Heterogeneous Small Cells, emergence of Small Cell Networks Deployment of super-small cells based on mmWave technologies Spectrum Sharing & Aggregation Self-Organizing Wireless Backhaul Dynamic Joint Access Backhaul (Mesh) Massive MIMO Deployment Advanced D2D (Thing-2- Thing) Scenarios e.g. Distributed MIMO Deep Edge Caching Local Traffic Distribution Local Services

SPECTRUM PROVIDER: Shared Spectrum Brokering Database Applying This Expertise – Network As A Service • Cloud Server provides Orchestration & Management to enable self-organized operation of heterogeneous Small Cell networks - Leverages heterogeneous networks (LTE, Wi-Fi) and multiple spectrum bands (licensed, ISM and shared spectrum) - Uses global and local policies to determine available spectrum and resources - Assigns channels, powers, etc. to help manage interference • Leverages crowd-sourced metrics collected from user devices and access points to manage the total network • Combined with SDN-based virtualization tools enabling efficient control of shared network resources (bandwidth, storage, backhaul) from a remote controller • Small Cells can be virtualized to support multi-tenancy, i.e. multiple operators sharing pool of Small Cell resources SELF- ORGANIZING SMALL CELL NETWORK Allocate Spectrum And Network Resources To Small Cells Request Resources/Metrics SMALL CELL ORCHESTRATION & MANAGEMENT Request/ Receive Spectrum APPLICATIONS QoS, Discovery, Analytics Middleware Platform Services Conduit Crowd-SourcedMetrics Small Cell Virtualization Radio Resource Management SON Edge Storage Spectrum Sharing Cloud Based MW Platform For RRM/SON & Virtualization

Service Provider A Service Provider B Service Provider C Small Cell Virtualization Small Cell as a Service One Interesting Use Case – Small Cell As A Service • Multi-tenancy enables virtualization and sharing of Small Cells amongst operators • Operators can share a Small Cell network or individual Small Cells • Virtualization coordinated by cloud middleware to allocate virtual Small Cell slices to operators • Small Cell network provider can be an operator or owner of real estate involved (e.g. shopping mall owner) Small Cell Cluster Shared Amongst Operators

It Is A Trend • This trend has been running for decades since the development of the core concepts of Server virtualization in IT industry • Introduction in the telco. domain began with the separation of the service logic from switching in SS7/AIN & continues today • The third wave is just beginning and holds great promise if we can leap beyond the pragmatic beginnings & obvious benefits • The third wave & the Network as a Service model can serve to completely rearchitect our industry value chain into a more sustainable model – Not a radical future but an essential one • Virtualization is driving our new economy and we must keep open minds to new virtualization possibilities in the future – This roadmap has been rolling for a long time & will continue • InterDigital is developing an orchestration and management solution for this future that can provide benefits today
