Abstract

Call drop rate in GSM (Global System for Mobile Communication) network is an important KPI that directly affects customer satisfaction. The delay in identification of exact call drop reason because of multiple reasons involved in it would result in poor performance of the network. The Radio frequency call drop (RF Call drop), handover failure call drops and LAPD (Link Access Protocol on D-Channel) call drops are the common types of call drops that are observed from the live GSM network. The procedure of resolving call drops has been discussed and a novel approach to identify exact root cause of call drops using pattern recognition technique is proposed.
