BKKGMW12-KPI


BKKGMW12-analysisCall drop due to lost UE connection and radio interface fail.


BKKGMW12-analysisFrom detected set cell check, the number of detected set cell many times with PSC221(KKTMMW11).


BKKGMW12-analysisFrom ASSLOG check, Id11 is reported by detect set, it means neighbor missing with PSC221.


BKKGMW12-analysisThe elevation is increase from BKKGMW.


BKKGMW12-analysisStep7: 2.6km-3.3km


BKKGMW12-analysisBKKGMW12 RSCP value from -85dBm to -95dBm alone the main road.


Suggestion add missing neighbor with PSC221(already added neighbor with PSC221 on 17:27 Feb 12th.) . add a small cell.

BKKGMW12-suggestionAfter add neighbor with PSC221, call drop rate decrease from 4% to 2%.

BSSUMW23-analysisStep7: 2.6km-3.3km


BSSUMW23-analysisThe elevation is increase from BSSUMW. Suspect the coverage become poor.
