Data CSSR & RRC CSSR & RRC Service & erab CSsr (%)- cluster level
Analysis:
The CSSR for Data, RRC,RRC service and eRAB of the neighbor sites are 99.71%, 99.89%, 99.94% and 99.82% which degraded compare with the baseline 99.79%, 99.93%, 99.95% and 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.
Meanwhile, there’s fluctuation during May, it was because of the Celcom-Sacofa 10GE migration implemented in MAY, the activity started in early May and rollback by end of May. The performance recovered from early June.

eRAB DCR(%) - cluster level
Analysis:
The eRAB DCR for the neighbor site is 0.17% which is worse than baseline 0.11% 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(%) - cluster level
Analysis:
The IRAT SR for the cluster is 97.48% which is worse than baseline 97.85% was mainly due to the CA layer management parameters changed on whole OKV.
The decreasing B2 Threshold and B2 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.

2G+3g+LTE Voice Traffic - Cluster Level
Analysis:
2G+3G+LTE Voice traffic is a little lower than baseline.
More users use Whatsapp/Wechat/Line to communicate instead of CS voice call.
In the meantime PS Traffic (2G+3G+LTE) has increased.
