Overview

Network sharing provides the following advantages for

operators:

Significantly reduced investment

Accelerated network deployment

Expanded network coverage

The infrastructure that can be shared includes sites,

equipment rooms, towers, and power suppliers.

Network equipment that can be shared includes base stations,

transmission equipment, and core network (CN) equipment.

Page5




Overview (Cont.)

eNodeBs support the following RAN sharing modes:

Independent operator mode: In this mode, the operators

cannot share their RAN resources due to geographic factors

but can share their RANs by allowing national roaming.

RAN sharing with common carriers: operators share RAN

resources, including carrier resources and eNodeB hardware

resources

RAN sharing with dedicated carriers: cell-level features are

configured for each individual operator, and eNodeB-level

features are shared between operators.

Independent Operator Mode

In operator A's network (home network), operator A serves this user.

After leaving operator A's network and roaming to operator B's network,

operator B serves the user.

RAN Sharing with Common Carriers

In RAN sharing with common carriers, the operators share

RAN resources, including carrier resources and eNodeB

hardware resources.

This mode applies to the following scenarios:

One operator is allocated with spectrum and can share the

spectrum with others.

Multiple operators are allocated with spectrum, and they can

contribute their spectrum to form a resource pool. They can share

the pool among themselves or with others who are not allocated

with spectrum.

Primary and secondary operators

The type of an operator is specified by theCnOperatorType parameter in a CnOperator MO.

The CnOperatorTa MO defines a TAC for an operator. The

CellOp MO defines an operator for a cell. All operators of a cell must be configured with the same

TAC. Specifically, the Tac parameters in the CnOperatorTa

MOs must be set to the same value. These MOs are

associated with the CellOp MOs of a cell through the

TrackingAreaId parameter.

EPC Selection

The UE notifies the eNodeB of

the selected EPC after the

radio resource control (RRC)

connection setup is complete. The eNodeB then selects the

corresponding S1 interface

based on the PLMN ID

selected by the UE.

Page14




Feature and Capacity Management

In RAN sharing with common carriers, a license purchase

order is placed by only one party.

Each eNodeB still has only one license file, which specifies

the total licensed limits for all RAN sharing operators, not fora specific operator.

Page15




Number of Active Users

The active users of the eNodeB can be distributed among

operators based on the proportions by using capacity

control items in the license.

The sum of proportions for all operators cannot be greaterthan 100%.

Page16




Traffic Volume

When operators purchase the license containing the traffic

volume control item, the total traffic volume can be allocated

to operators based on the proportions specified below.

If the parameter is set to SHARING(Sharing), all operatorsshare the total traffic volume of the eNodeB.

Resources

To ensure fair sharing of radio resources, the parameters

below should be configured according to operators’

agreement.

RAN Sharing with Dedicated Carriers

Page20




RAN Sharing with Dedicated Carriers

(Cont.)

RAN sharing with dedicated carriers is transparent to UEs

and EPCs because operators have their own cells and a

shared eNodeB uses different identifiers to communicate

with different EPCs. As a result, RAN sharing with

dedicated carriers does not have additional requirements

for UEs and EPCs.

In RAN sharing with dedicated carriers, cell-level features

are configured for each individual operator , and

eNodeB-level features are shared between operators.
