Hi,
In T-mobile (and E*******)'s UMTS Network KPI, the definition of HSDPA Access Failure Rate (Drive Test) is:
HSDPA Access Failure Rate = [1 - (No_Activate PDP Context Accept of HSDPA Sessions)/(No_RRC Connection Request of HSDPA Sessions)] x 100%. It is the same as the definition of R99 PSD Access Failure rate, except that the sessions are HSDPA.
However, in Nokia-Siemens KPI, HSDPA Setup Success Rate is the ratio between successfully selected HSDPA compared to the number HSDPA attempts. The successful selected HSDPA is defined between Radio Bearer reconfiguration messages (where UE is commanded to HSDPA). The corresponding attempt is submission of the UL-DCCH Measurement report (e4A) message.
So, my question is what is the right definition and how to get this paramter from TEMS and Actix?
Thanks in advance
