IU Paging Success Ratio defied for Huawei system.
 
IU Paging Success Ratio = 
(VS.RANAP.Paging.Succ.IdleUE/ VS.RANAP.Paging.Att.IdleUE)*100%
 
This KPI can be used to evaluate the successful paging responses to the 
pagings from the Core Network (CN) in one RNC.
The Attempt Paging Procedure starts when the CN sends a PAGING message to the 
RNC, and finishes when the UE in idle mode receives the PAGING TYPE 1 message 
from the RNC.
The Successful Paging Procedure finishes when the RNC receives an RRC 
CONNECTION REQUEST from the UE in idle mode.
(VS.RANAP.Paging.Succ.IdleUE/ VS.RANAP.Paging.Att.IdleUE)*100%
