  • 1. Analysing the Network Sharing Opportunity Thierry DUPONT - Project Manager May 23rd 2012
  • 2. TDF, in Brief TV and Radio Broadcast Leader in Europe  11150 sites operated in Europe  8730 in France  More than 1500 customers  Digital Transport Network  Management and Distribution of Audio, Video and Data Contents  Creation of Innovative Solutions  Connected DTT, Video on Demand, Catch-up TV  Digital Cinema, 3D Mobile Network Operators Partner  More than 20 % of the Sales  Sites Housing  Operations & Maintenance 1
  • 3. LTE Shared Network LTE standard includes natively sharing model  National Roaming  Passive Sharing  Active Sharing MOCN GWCN All IP Networks Active Sharing Business Model  Wholesalers  Joint Ventures  Geographic Split 2

  • 5. TDF PoC EPC EPC Media Broadcast Telehouse2 RAN TMS4
  • 6. Multi Operator Core Network with shared spectrum RAN is shared between multiple MNOs Each MNO manages it’s own EPC 2 Types of services in LTE  Guaranteed Bit Rate  non-GBR Problematic :  Fairness between MNO  Capacity Reservation of each MNO for  GBR Services  non-GBR Services 5
  • 7. Multi Operator Core Network with shared spectrum GBR Services Through Admission Control Fully splitted  GBR eRAB initiation within the reserved capacity Fully Fully Partial  Configuration with less performance splitted shared shared Fully shared  GBR eRAB initiation without restriction UNUSED SHARED for GBR  Optimal Configuration 50% 50%  No Limitation and no Guarantee Partial shared SHARED 50%  GBR eRAB initiation within the reserved capacity MNO A MNO A and the shared part 30% 30%  Mix between split and shared  Pbe of equity if an MNO preempts the shared part MNO B MNO B 20% 20% 6
  • 8. TDF Network Sharing Implementation  Based on the dynamic allocation of Physical Resource Block  Each MNO can use the total amount of PRBs  In case of congestion, each MNO has it’s percentage of PRB Reserved7
  • 9. LTE QoS8
  • 10. LTE QoS QCI Table9
  • 11. Building Differentiated QoS flows for each MNO  MOCN Configuration  MNO A: 70 %  MNO B: 30%  QoS Configuration per MNO  UE A, UE B2 and UE B3 with QCI 9 (BE)  UE B1 with QCI 3 (Gold Subs)  Results in case of congestion  UE A uses 70 % of PRB  UEs from MNO B use 30 % of PRB  UE B1 : Video Stream without degradation  UE B2 : Video Stream Degradation  UE B3 ; Download Degradation10
  • 12. Home User entering LTE MOCN Cell Each Cell broadcasts Operators PLMN IDs  Through SIB UE decodes broadcast message and selects its HPLMN UE informs the e-UTRAN of the selected PLMN-id The Shared eNodeB routes the UE to the CN according to the selected PLMN-id 11
  • 13. Handover User entering LTE MOCN Cell Serving PLMN Id remains unchanged after X2-based Handover For S1-based Handover or inter RAT Handover, the eNodeB will know the serving CN according to MME Handover Request Message 12
  • 14. Handover using X2 interface13
