Data CSSR & RRC CSSR & RRC Service & erab CSsr (%)
Analysis:
The CSSR for Data ,RRC,RRC service and eRAB of the cluster sites are 99.68%, 99.85%, 99.94%, 99.82% which has a slight degradation compare with the baseline 99.76%, 99.90%, 99.95%, 99.86%.
The degradation is mainly cause by the adjusting of qrxlevmin (from -120 to -124) which aiming to keep more users on 4G, the subscribe at the cell edge will stick to LTE with low poor RF condition while the 4G total volume increased as a result, it’s an exceptional decrease just as below summary in mail;

CSFB Setup SR(%)
Analysis:
The CSFB Setup SR for the neighbor site is 99.79% which is a litter worse than baseline 99.86% ,it is normal fluctuation;

eRAB DCR(%)
Analysis:
The eRAB DCR for the cluster site is 0.17% which is worse than baseline 0.10% was mainly due to the CA layer management parameters changed on whole OKV.
CA layer management parameters was aiming to keep more users on 4G, which means the subscribe in cell edge will stick to LTE with low poor RF condition while the 4G total volume increased as a result, it’s an exceptional decrease just as below summary in mail;

IRAT(%)
Analysis:
The IRAT SR Rate for the sites is 97% which is worse than baseline 98.12% was mainly due to the CA layer management parameters changed on whole OKV.
The decreasing B2 and A2&Timer adjustment were aiming to keep more users on 4G, it’s harder to transfer to WCDMA for UE in cell edge than before, which means the subscribe will stick to LTE with low poor RF condition while the 4G total volume increased as a result, it’s an exceptional decrease just as below summary in mail;
