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

GBR eRAB initiation within the reserved capacity
Configuration with less performance
Fully shared
GBR eRAB initiation without restriction
Optimal Configuration
No Limitation and no Guarantee
Partial shared
GBR eRAB initiation within the reserved capacity
and the shared part
Mix between split and shared
Pbe of equity if an MNO preempts the shared part
7
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 Reserved

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 Degradation

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
12
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
