Retainability - HSDPA Call Drop Rate
• KPI name: HSDPA Call Drop Rate
• Scope: Cell & RNC
• KPI formula:- Cell (RAN12): ([VS.HSDPA.RAB.AbnormRel]/([VS.HSDPA.RAB.AbnormRel]+[VS.HSDPA.RAB.NormRel]+[VS.HSDPA.H2D.Succ]+[VS.HSDPA.H2F.Succ]+[VS.HSDPA.HHO.H2D.SuccOutIntraFreq]+[VS.HSDPA.HHO.H2D.SuccOutInterFreq]))*{100}
- RNC (RAN12): The RNC level KPI is calculated by aggregating all the cell counters.
• Unit: %
• Use case: Measures HSDPA service call drops. The RNC level formula does not include drops over Iur. The HSDPA RAB releases due to channel change (HS-DSCH to DCH/HS-DSCH to FACH, intra-cell/inter-cell) are measured separately and they are normal releases as well.
• Reference Values: KPI should have a value below 1% in live network.

Retainability - HSUPA Call Drop Rate
• KPI name: HSUPA Call Drop Rate
• Scope: Cell & RNC
• KPI formula:- Cell (RAN12): ([VS.HSUPA.RAB.AbnormRel]/([VS.HSUPA.RAB.AbnormRel]+[VS.HSUPA.RAB.NormRel]+[VS.HSUPA.HHO.E2D.SuccOutIntraFreq]+[VS.HSUPA.HHO.E2D.SuccOutInterFreq]+[VS.HSUPA.E2F.Succ]+[VS.HSUPA.E2D.Succ]))*{100}
- RNC (RAN12): The RNC level KPI is calculated by aggregating all the cell counters.
• Unit: %
• Use case: Measures HSUPA service call drops. The RNC level formula does not include drops over Iur. The HSUPA RAB releases due to channel change (E-DCH to DCH/E-DCH to FACH, intra-cell/inter-cell) are measured separately and they are normal releases as well.
• Reference Values: KPI should have a value below 1% in live network.
