Estimation of market share by using discretization technology: An application in china mobile

Abstract

The mobile market is becoming more competitive. Mobile operators having been focusing on the market share of high quality customers. In this paper, we propose a new method to help mobile operator to estimate the share in high quality customers market based on the available data, inter-network calling detail records. The core of our method is a discretization algorithm which adopts the Gini criterion as discretization measure and is supervised, global and static. In order to evaluate the model, we use the real life data come from one mobile operator in China mainland. The results prove that our method is effective. And also our method is simple and easy to be incorporated into operation support system to predict periodically © 2008 Springer-Verlag Berlin Heidelberg.
