Multi Operator Core Network with shared spectrum

RAN is shared between multiple MNOs

Each MNO manages it’s own EPC

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

11

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
