Case Study - Telecom

Telecommunication Sector: Improved business operations and planning efficiency by transforming call data record (CDR) data to real-time business intelligence system supporting decision making across the various business units of the company
The Problem
A telecom giant, with over 5 million subscribers has an older legacy business intelligence system which can no longer cope with handling the huge volume of input data files. Reports generation takes hours to produce, and often end up being inaccurate. Daily man-hour spent on report generation was enormous leaving the supporting IT staff with little or no time for other critical IT functions. Revenue assurance, marketing, product development etc. teams do not the need visibility to function properly.

Typically, about 10 data files per minute are extracted from the CDR files and sent for analysis. On the average, each file is over 10 Mbytes in size, and contains over 250,000 records. Hence, the solution is to process over 250 million call data records per day - from just one data-source alone. The files are to be processed as soon as they become available, so that dashboards and scheduled reports will be updated in near real-time.

This telecom giant turned to UnlimitedAnalytics to address this critical business problem.

The Solution
UnlimitedAnalytics is data-source and data-format independent. Hence, there was no need to introduce any new business logic; the system was only configured to map their data-sources (CDR data files - the main) for real-time uploading, ingestion, and reporting generation, visualization, and distribution (manual and automated):

  • Which UnlimitedAnalytics solution implementations is required? Choosing between using the UnlimitedAnalytics cloud service or have it implemented on-premise: the company preferred on-premise implementation on their infrastructure (private cloud) - this was particularly preferred as the size of the call data record files generated every 10 minutes is huge.
  • Identify all data-sources that were to serve as data input for the integrated enterprise data analytics and reporting solution.
  • Identify fields within the CDR file record that are not required in any report, such were excluded from ingestion, and analysis during the data-source configuration phase
  • Identify the levels of the data aggregation desired by the various business units
  • Identify the internal and external reports needed by the various business units; when and how they need these reports to be composed, published and scheduled for automated generation and distribution.
  • The CDR files is pushed to the UnlimitedAnalytics system every 10 minutes
  • Data Ingestions commences once data files becomes available, the process is completed before new files are pushed
  • Identify the various Dashboard views needed by different business units. These should be refreshed every 10 minutes to display new report based on the last data ingestion process
  • Identify which fields in the CDR file is needed in any analysis
  • Identify all the data sources that are required to generate the reports
