Issue Description and Analysis

1.Here the target area encouters a weak SINR and due to that it is jointion of several cell edges. 2 cells overshoots here, namely LMU0041A and LMU0230A. Need to down tilt down by 2 degrees and 4 degrees.And by launch, there will intergrate a new site LMU0004, which will improve the SINR.

2. Similar situation as abrove. And there is no domainate cell. LMU0394B needs tilting up from 8 degrees to 5 degrees.By launch, there is another new site LMU0393 at the marked place.

3.LMU0039A needs tilting down by 3 degrees and LMU0048C tilting down by 4 degrees.LMU0037 needs tilting up by 2 degrees.

DriveTest KPI

Formula

Result evaluation: Average rudimental BLER recorded in Probe and Assistant

C-Plane Latency Intra frequency HO = T(handoff_complete)- T(handoff_command)



RRC Connection Establishment Success Rate = Number of RRC Connection Establishment Success / Number of RRC Connection Establishment Attempt * 100%

Attach failure Rate = 1- Number of LTE Attach Complete/ Number of LTE Attach Request

Service Request Failure Rate = 1-RRC setup success rate*ERAB setup success rate(%)

Service Request Delay = T(RRCRecfgComplete)-T(RRCConnectionRequest);excluded the Service request failure delay

*Exclude the unreasonable latency due to service request not finished but reselect to other cells

ERAB Establishment Success Rate = Number of ERAB Establishment Success / Number of ERAB Establishment Attempt * 100%

Call drop rate = Number of E-RAB Abnormal Release / Number of E-RAB Setup Success * 100%

DT Tool cannot measure this value as it is layer-2 measurement. But this procedure included in idle to Active and Handover.

Handover Successful Rate = Number of Intra Freq Handover Success / (Number of Intra Freq Handover Success + Number of Intra Freq HO Failure) * 100%;

IRAT handover Success Rate =LTEInterRATRedirectionSuc Counter/ (LTEInterRATRedirectionSuc Counter+ LTEInterRATRedirectionfail Counter)*100%

Handover Successful Rate = Number of Intra Freq Handover Success / (Number of Intra Freq Handover Success + Number of Intra Freq HO Failure) * 100%;

IRAT handover Success Rate =LTEInterRATRedirectionSuc Counter/ (LTEInterRATRedirectionSuc Counter+ LTEInterRATRedirectionfail Counter)*100%
