BSC6810 and BSC6900 Dimensioning

Confidential Information of Huawei. No Spreading Without Permission

� Legacy boards


� Supported in RAN10.0 (BSC6810) and RAN11.0 (BSC6810) and RAN11.1 (BSC6900)

� Upgrade from RAN10.0 to RAN11.0

� Performance improvement

� New RAN features

� More flexible configuration depending on customer specific CP / UP requirements

� Upgrade from RAN11.0 to RAN11.1 does not bring performance improvement with legacy boards.

� New boards

� Introduced in RAN11.1 (BSC6900)

� Major performance improvement (wrt legacy boards in RAN11.0)

� New boards : SPUb, DPUe, FG2c, GOUc, POUc, AOUc, UOIc


� BHCA capacity is based on Huawei’s call model


� SPU and DPU capacity are quoted per board

� Redundancy

� SPU boards are configured per pair, active:stand-by for 1:1 redundancy

� DPU boards operate in load sharing mode, i.e. all boards active

� DPUb boards are configured per pair in all RAN releases

� DPUe is available as a single board (not just per pair) due to its much enhanced capacity

� Basic Models



� No new RNC boards in RAN12 but new nomenclature is introduced


� Objective = Identify specific hardware required to support all RNC functionalities

� HW68R11 = legacy boards used in BSC6810

� HW69R11 = new boards introduced in BSC6900 with RAN11.1(also include “legacy” boards not superseded by a newer version)

� Both hardware versions HW68R11 and HW69R11 are supported in BSC6900 with RAN12.0


� Differences between RAN11.1 and RAN12.0 Basic Model configurations


� Increased CP capacity :More pairs of SPUb are supported in RAN12.0

� Increased UP capacity :New hardware capacity license 165Mbps is introduced in RAN12 for DPUe board

DPUe capacity = 335Mbps w/o license and 500Mbps w/ license

� Max. RNC configuration = 80,400 Erl / 12 Gbps / 3,220K BHCA / 3,060 NodeBs / 5,100 cells

� IP type boards : PEUa, FG2a, GOUa, POUa, UOIa_IP;

� ATM type boards : AEUa, AOUa, UOIa_ATM;
