Call Drop Analysis

Call Drops directly impact the primary offering of a Telco i.e. Voice. It also has a major influence on the perception of the customer on the Quality of Service offered by a Telco. Also stringent regulatory norms in every country make it all the more important for Telcos to focus on the same for all the areas they cater to. It is thus convenient if a Telco could have a single view of the call drops on his networks around the globe and be alerted in quick time, in case of any breach in expected call quality measures.

  • It is difficult to analyze the reason for call drops since the volume of voice data generated is huge and the reason for call drops are varied – network failures, customer handset compatibility issues, handover issues, credit limit, outstanding balance, etc.
  • Dissatisfied customers may not always report on frequent call drops but would have a greater propensity to churn out in search of better services/coverage
  • Analyze CDR data generated by customers, correlate with corresponding time interval network device logs and classify the reasons for call drops
  • Drill-down dashboards which present a region-wise analysis on rate of call drops, reason for call drops and propose resolution to concerned Telco departments is developed
  • Enhanced visualizations which assist in tracing location information based on frequency & revenue loss due to call drop reasons are presented for analysis
  • Subscriber calling pattern is considered for calculation of revenue-loss per subscriber. Reports are generated on a Revenue Dashboard to indicate total revenue-loss categorized per Base Station/Area/Division/City
