UTRAN Call Setup
UTRAN Call Setup includes the RRC connection setup and the RAB establish procedure. The essful call setup involves the ess RRC and RAB setup. The main indicators are
RRC Setup ess Rate
RAB Setup ess Rate
RRC Setup Counter
Measurement Point
Stat. Number of RRC Connection Request in Point A1 of Figure1
Stat. Number of RRC Connection Setup in Point B of Figure1
Stat. Number of RRC Connection plete in Point C of Figure1
Stat. Number of RRC Connection Reject in point A of Figure2
F1:essful RRC connection setup procedure F2: RRC connection reject procedure
RRC Setup Counter
RRC Setup KPI
RRC Connection Setup ess Rate = RRC Connection plete / RRC Connection Request
