Context and objective of this demo event

■  COMBO – COnvergence of fixed and Mobile BrOadband access/aggregation networks – is an FP7 European project on convergence of fixed and mobile networks, with three main targets: ♦  Target 1: Define and develop FMC architectures for future

networks, which will be technically assessed with respect to FMC use cases defined by the project

♦  Target 2: Demonstrate experimentally key FMC network features to show the feasibility of proposed architectures

♦  Target 3: Influence standardization bodies with respect to FMC architectures to push COMBO concepts

■  This demo event intends to present main outcomes and proofs of concept obtained by the project up to now, with a specific focus on experimental results (target 2)



Main COMBO concepts



1. Network FMC and COMBO project vision



What is network Fixed and Mobile Convergence (FMC)


Common architecture for fixed and mobile network requires interaction at different points: §  Structural convergence

§  Common use of resources e.g. infrastructure, technology, interfaces, transport mechanisms

§  Functional convergence §  Unification of fixed and mobile

network functions

Fixed and mobile networks §  are developed independently of

each other §  have only very limited joint

usage of infrastructure §  have independent network

operation, control and management

FMC only at service level (e.g. IP Multimedia Subsystem)

Why network FMC is needed for 5G design


•  Increasing number of users and connected devices

•  Need to access any content any time anywhere with any device

•  Bandwidth-hungry usages of fixed and mobile customers, driven by video streaming

•  Increasing Wi-Fi traffic coming from mobile terminals

•  A resulting tight price pressure on telcos requiring significant CapEx and OpEx reductions

•  Unification of hardware resources (equipment, cables, sites, etc.) for both fixed and mobile services

•  Cost and energy savings •  Simplification of fixed and

mobile network architectures •  Ease of use, ease of operation

and network sharing capabilities •  Network FMC will enable a

5G infrastructure with end-to-end management and orchestration

Drivers Expected benefits from network FMC

COMBO project vision in a nutshell


■  COMBO targets structural and functional convergence of fixed and mobile networks •  Integration of backhaul/fronthaul with fixed access / aggregation •  Integration of unified fixed and mobile functions in key functional

blocks and functional entities

■  COMBO defines network scenarios based on Next Generation Point of Presence (NG-POP), as the location for the subscriber IP edge of fixed, Wi-Fi and mobile networks •  distributed NG-POPs @ main COs •  centralized NG-POPs @ core COs

■  COMBO defines a Universal Access Gateway (UAG) as a functional entity unifying user access to fixed and mobile networks •  UAG data planes include the common subscriber

IP edge for fixed, mobile and Wi-Fi and are located in NG-POPs

Structural convergence



2. Structural convergence



Heterogeneous Radio Access Networks will trigger structural convergence


■  Larger number of antenna locations

■  Required RAN coordination (small and macro cells)

■  Much more capillarity and dynamicity required from back-/fronthauling infrastructures


Structural convergence Unified optical access / aggregation network


■  Features of the unified optical access / aggregation •  Converged physical layer functions supporting heterogeneous

access services for fixed, mobile and Wi-Fi •  Low latency and high capacity required for fronthaul transport •  Compatibility with legacy infrastructures, e.g. existing Optical

Distribution Networks

■  Different flavors have been studied and experimented by COMBO •  based on Next Generation Passive Optical Network 2 (NG-PON2)

o  either on Wavelength-Selective or Wavelength-Routed Optical Distribution Network

o  including centralized wavelength control and improved with low latency electrical crossconnect

•  or based on Dense WDM (DWDM) flexible photonic transport technologies o  including joint orchestration of RAN, transport and cloud resources

3. Functional convergence



Functional convergence uAUT and uDPM as functional enablers for FMC


■  universal subscriber and user AUThentication (uAUT) •  A set of functions that allows a user to authenticate once and

have access to multiple networks and/or services •  It avoids the drawbacks of the proliferation of identities, user/

subscriber profiles and authentication mechanisms in fixed and mobile networks

■  universal Data Path Management (uDPM) •  A set of functions that allows redirecting (part) of mobile data

traffic over the fixed/Wi-Fi data paths or vice versa •  while maintaining session continuity •  and enabling multiple data paths to be used simultaneously for a

given user session and its individual traffic flows


High-level functional view of UAG – links with uAUT and uDPM

■  Fixed Access Node = OLT

■  Wi-Fi Access Node = Wi-Fi Access Point

■  Mobile Access Node = eNodeB (or BBU or BBU hotel)

■  Network interfaces make connection between nodes: no processing of subscriber IP traffic

■  Subscriber interfaces are logical interfaces at subscriber level, connecting UE or CPE to UAG data plane
