Page5 . Ltd. transmission equipment. All rights reserved. towers. and eNodeB-level features are shared between operators. Ltd.  RAN sharing with common carriers: operators share RAN resources.. the operators cannot share their RAN resources due to geographic factors but can share their RANs by allowing national roaming.Overview (Cont. All rights reserved. including carrier resources and eNodeB hardware resources  RAN sharing with dedicated carriers: cell-level features are configured for each individual operator. Copyright © 2013 Huawei Technologies Co.)  eNodeBs support the following RAN sharing modes:  Independent operator mode: In this mode. Page6 . Ltd. Page7 .Overview (Cont..

Ltd. Ltd. Copyright © 2013 Huawei Technologies Co.  This mode applies to the following scenarios:  One operator is allocated with spectrum and can share the spectrum with others. They can share the pool among themselves or with others who are not allocated with spectrum.  Multiple operators are allocated with spectrum. including carrier resources and eNodeB hardware resources. Page10 . the operators share RAN resources. All rights reserved. and they can contribute their spectrum to form a resource pool.RAN Sharing with Common Carriers  In RAN sharing with common carriers.. Page11 .. All rights reserved.)

Copyright © 2013 Huawei Technologies Co. Specifically. the Tac parameters in the CnOperatorTa MOs must be set to the same value. The CellOp MO defines an operator for a cell.. Ltd.  The CnOperatorTa MO defines a TAC for an operator. Page12 . These MOs are associated with the CellOp MOs of a cell through the TrackingAreaId parameter.Primary and secondary operators  The type of an operator is specified by the CnOperatorType parameter in a CnOperator MO.

All rights reserved.  The sum of proportions for all operators cannot be greater than 100%. Page16 . Ltd.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. Copyright © 2013 Huawei Technologies Co. .Traffic Volume  When operators purchase the license containing the traffic volume control item.  If the parameter is set to SHARING(Sharing). Page17 . the total traffic volume can be allocated to operators based on the proportions specified below. Copyright © 2013 Huawei Technologies Co.

Copyright © 2013 Huawei Technologies Co.)  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.
