摘要

Drop data call is process of undesired traffic channel termination which frequently occur in cellular network andmust immediately repaired to keep reliability. Currently, it take a long time to find dozens or hundreds drop data call causes on drive test log file without any standard parameters as consideration which arranged neatly on flow chart. Using this method, 90 drop data call causes have been found from total 102 that occurred. Five main drop causes from Cluster 5 West Java region is: coverage problem, overshooting problem, dominance problem, handoff failure and edge cell problem. With those five problems recovered, it has improved CDR (Connection Drop Rate) from 7.07% into 1.387% which is below than 2% (Smartfren's KPI).
