Dear Optimi,

Have encountered the same problem, KPI is HSDPA_Setup_Failure_due_to_UE , counters incrementing is SETUP_FAIL_UE_HS_DSCH_INT

If the Sector Identifier incorrectly configured would cause the UE to fail, correction of this caused improvement in HSDPA accessibility and reduction of Failures due to UE

You mean the sector Id was incorrectly configured at a particular site?

But these failures are on every site, difference being some have more failures than others. However these failures are rarely many enough to cause a significant degradation.

Sometimes a BTS reset will help clear them as it could be a software glitch or a faulty FSME

If Enabled then:

-The primary target of this feature is to direct the HSDPA UE to -> the cell that supports HSDPA




-non-HSDPA UE is removed from HSDPA layer




-If several HSDPA capable layers exist, the HSDPA load balancing between these layers is used




But before you enabled this parameter, make sure that each cells within same sector must have the same coverage of CPICH.
