4 Main target and objectives Main target COMBO targets a unified access and aggregation network by converging fixed and mobile networks (Fixed / Mobile network Convergence, FMC), enabling: optimal and seamless quality of experience for the enduser improved network structure ensuring reduced cost and energy consumption while bandwidth is increasing Objectives Define optimised FMC Textbox architectures Assess multi-operator FMC scenarios Demonstrate experimentally FMC in lab tests and field trials Drive standardization bodies with respect to FMC architectures 05/07/2013 Future Network & Mobile Summit Lisbon - NG-POP 4

5 Motivations for convergence Motivation In the past, fixed and mobile access networks have been optimized and evolved independently, with partly contradicting trends Access infrastructures represent long term investments (> 50% of total ICT) and about 90% of network energy consumption: a sustainable network evolution strategy is required for the next decade Focus area Level of integration and functional distribution needs to be investigated and optimized 2G/3G Wi-Fi Wireless 4G (LTE/LTE-Advanced) Fixed Macro Pico Mobile 5G Converged Broadband Fixed and Mobile Access/Aggregation Network λ 1 λ N λ 1 λ N BBU-H OLT BBU-H OLT Edge Router Mobile Core Components 4G MME S-GW P-GW 2G/3G MSC SGSN GGSN Fixed Core Components BB-RAR COMBO LER IPTV Web Service Control Layer IMS/TISPAN IP/MPLS Backbone Network Control Layer OSS, Synchronization, Platform Control 05/07/2013 Future Network & Mobile Summit Lisbon - NG-POP 5

10 Structural convergence in a multi-operator environment OP1 OP2 OP3 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 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 05/07/2013 Future Network & Mobile Summit Lisbon - NG-POP 10

11 Some enablers for convergence Functional 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 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 05/07/2013 Future Network & Mobile Summit Lisbon - NG-POP 11

12 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 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 05/07/2013 Future Network & Mobile Summit Lisbon - NG-POP 12

15 Some key questions and requirements Key questions Which are the optimum levels of convergence? Which network functions and equipment should be centralized or distributed? How will convergence impact handover mechanisms? How will convergence impact data traffic? Key requirements Increasing traffic and changing applications Reduced network cost and energy Openness of network interfaces Seamless performance monitoring and management Multi service flexible network to cope with future services 05/07/2013 Future Network & Mobile Summit Lisbon - NG-POP 15
