CS and PS IFHO SR (98.50%, 98.10%) didn’t pass the target (98.93%, 98.41%) as KPIs degraded slightly after baseline alignment on 10th April. NonUsedFreqThresh4_2bEcno is changed from -10dB to -13dB, so IFHO could be triggered when target cell has poorer quality than before, causing IFHO failures increased. © Ericsson AB 2016

Hammer Project KV020 S-KPI CBO 2016-08-26 Data CSSR & RRC CSSR & RRC Service & erab CSsr (%) Analysis: The CSSR for Data ,RRC,RRC service and eRAB of the cluster sites are 99.73%, 99.90%, 99.94%, 99.83% which has a slight degradation compare with the baseline 99.80%, 99.94%, 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; Baseline Result qrxlevmin © Ericsson AB 2016

Hammer Project KV020 S-KPI CBO 2016-08-26 CSFB Setup SR(%) Analysis: The CSFB Setup SR for the neighbor site is 99.94% which is a litter worse than baseline 99.95% ,it is normal fluctuation; Baseline Result Normal fluctuation © Ericsson AB 2016

Hammer Project KV020 S-KPI CBO 2016-08-26 eRAB DCR(%) Analysis: The eRAB DCR for the cluster site is 0.13% 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; Baseline Result CA layer management parameters change © Ericsson AB 2016

Hammer Project CA SSO Report 2017-05-05 Network Availability Analysis: The Network Availability Cell Level is 99.35% which is worse than baseline 99.73% was mainly due to several sites had the PLMN Service Unavailable alarm during 5/23/2017-5/29/2017. © Ericsson AB 2017

Hammer Project KV020 S-KPI CBO 2016-08-26 IRAT(%) Analysis: The IRAT SR Rate for the sites is 97.49% which is worse than baseline 97.89% was mainly due to the CA layer management parameters changed on whole OKV. The decreasing B2 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; Baseline Result B2 B2 Timer © Ericsson AB 2016
