In this paper, the authors 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.
