Of the numerous performance metrics applied to cellular telephone systems, probably none is more important for customer satisfaction than the system drop call rate. Customers are more sensitive to call dropping than to call blocking at initiation. Proper system design and operation involve keeping the drop call rate as low as possible. Today a number of mobile subscribers are grappling with the issue of frequent call disconnections or ‘call drop ‘ Dropped call is the common term used for describing any unexpected termination of a wireless mobile call. There are numerous drop call causes in cellular networks with majority of them occurring due to lack of radio resources created by electromagnetic causes and user mobility (i.e. handover). Another important contributor of call rate is the traffic load in which, the call arrival rate and holding time play significant roles(1). Drop call probability is defined as the probability that a call is terminated due to one or all of the above-mentioned causes. Drop call probability has been the subject of several network performance studies and a major contributor to service optimization in established cellular. In this paper, we present an overview of drop–call probability factors in cellular networks.
