Introduction

A national mobile carrier was consistently ranked in the bottom half of the telecom industry on voice coverage in 125 metropolitan areas.  The company engaged ProCogia to develop a system for precision monitoring, identification, and isolation of call-coverage deficiencies.

We significantly improved troubleshooting performance with real-time detection of daily deficient calls and precise geolocation of areas experiencing poor coverage. In 2017, the mobile carrier earned first or second place in industry voice-performance rankings in 39% of 125 metropolitan areas, and improved call reliability by 30%.

 
 

The Challenge

A national mobile carrier was consistently ranked in the bottom half of the telecom industry on voice coverage in 125 metropolitan areas.  The company engaged ProCogia to develop a system for precision monitoring, identification, and isolation of call-coverage deficiencies.

Procogia’s Approach

ProCogia assembled a cross-functional team of data strategists, engineers, and scientists. Our process included:

 

 

  • Identify network features related to deficient calls via exploratory analyses and collaboration with client’s engineering team.
  • Use pattern mining to identify poor network performance and pinpoint precise geolocation of the deficient calls.
  • Develop a call-classification logic around influential network features and validate with computational simulations of network performance tests. Create a model that accurately predicts voice scores published on reports.
  • Measure results from computational simulations and voice score prediction against rates and scores published in reports. Identify the highest performing call- classification logic.
  • Productionize automated daily interactive dashboards on the status of testing and performance across US.

The Results

  • ProCogia’s solution significantly improved the mobile carrier’s troubleshooting performance with real-time detection of daily deficient calls and precise geolocation of areas experiencing poor coverage.
  • In 2017, the company earned first or second place in industry voice-performance rankings in 39% of 125 metropolitan areas, and improved call reliability by 30%.
