Main target and objectives

Textbox� Define optimised FMC

architectures

� Assess multi-operator FMC scenarios

Main target

COMBO targets a unified access and aggregation network by converging fixed and mobile networks (Fixed / Mobile network Convergence, FMC), enabling:

Objectives



scenarios

� Demonstrate experimentally FMC in lab tests and field trials

� Drive standardization bodies with respect to FMC architectures

• optimal and seamless quality of experience for the end-user

• improved network structure ensuring reduced cost and energy consumption while bandwidth is increasing

Motivations for convergence

• In the past, fixed and mobile access networks have been optimized and evolved independently, with partly contradicting trends

� Level of integration and functional distribution needs to be investigated and optimized

Several functional blocks of different nature need to be considered (access, networking, content, services)

Structural convergence in a multi-operatorenvironment


■ Structural convergence targets mutualization:♦ Mutualization of locations (NG-POP)♦ Mutualization of fibre infrastructure♦ Usage of the same technologies♦ Integration of fixed and mobile access equipment

Mobile operator sharing NG-POP and tower of OP2 but using its own equipment

OP2 provides converged network to the other operators and hosts co-location point at NGPOP and tower

OP3 uses the co-location points of OP2 and also the FMC network resources and functions of OP2

Some enablers for convergence

� Unified control mechanisms� Advanced sleep modes� Streamlining of protocol stack� Generalized 3D handover mechanisms� Advanced network-level offloading schemes� Openness of network interfaces� Harmonization of authentication and subscriber

management

Functional convergence



management

Structural convergence

� Optical access node concentration� Heterogeneous radio access networks� BBU hostelling with resource pooling� Mobile fronthaul technologies based on Digital Radio over

Fibre (D-RoF)� Multi-wavelength and multi-service optical access and

aggregation technologies

Conclusions

■ Making fixed and mobile networks converge is a desirable though very complex target for network operators and vendors

■ Better integration of fixed and mobile networks would result in both ♦ an optimal and seamless quality of experience for the end user♦ an improved network infrastructure ensuring increased performance, reduced

cost and also reduced energy consumption


cost and also reduced energy consumption

■ COMBO is designing a unified access and aggregation architecture leading to Fixed-Mobile Convergence♦ based on Next Generation Point of Presence♦ with a better distribution of all essential functions, equipment and infrastructures

of convergent networks♦ enabling a network with better services at lower operational costs
