The Effects of Ostentatious Calls in GSM Networks

Abstract

In this paper, we investigate the possible effect of ostentatious (flash) calls in mobile communication networks (GSM) in Nigeria. The GSM network consists of physical and logical channels used to convey digit information signal from one network element to another. The Globacom network in Nigeria was investigated in a period of one year duration. An average traffic data (A-interface MSC) were collected from the OMC-network element. Also, it was observed from the result analysis that complete calls which is a major factor in revenue generation consist of both answer calls with 42 percentage and unanswered calls with 58 percentages. These unanswered calls are made up of both redial calls and ostentatious (flash) calls which are transmitted through the limited transmission channels without financial benefit accrue to the mobile communication operators. It were deduced from investigation that the traffic in erlang for average number of unanswered calls in 1 hour is 4151.92 erlang and one (1) call is 0.0023 erlang. In this paper, we highlighted the possible effects of unanswered calls, solutions of reducing the high number of unanswered calls and reduction in unanswered calls will leads to remarkable low number of block calls experience in the Mobile Communication network (GSM).
