Clustering GSM subscribes for telecom churn management

Abstract

Mobile telecommunication sector has been accelerated with GSM 1800 licenses in the Turkey. Since then, churn management has won vital importance for the GSM operators. Customers should have segmented according to their profitability for the chum management. If we know the profitable customer segments, we have chance to keep in hand the most important customers via the suitable promotions and campaigns. In this study, we implemented clustering algorithms to 250 subscribers' 100MBs call detail records(CDRs), demographic data and billing information. Density-Based Spatial Clustering of Applications with Noise (DBSCAN) compared with K-Means, Expectation Maximization and Farthest-First clustering techniques. As a result, DBSCAN has good distinct clusters for profiling customer segments. © 2008 Elsevier B.V., All rights reserved.
