Abstract
Network congestion and signal quality degradation are the major problems of the Global System for Mobile communication (GSM), most especially as the number of customers increases. Consequently, there is a pressing demand for further research to improve network performance. However, congestion in various systems has always been tackled with various attempts, all of which falls in either the congestion avoidance category or congestion management category. Congestion avoidance has however been adjudged the best scheme for controlling network congestion and this is the approach employed in this research work. This research work is focused on determination of a busy BTS(s) within different GSM network areas, and how to manage the BTS(s) in order to reduce call blocking/dropping to the barest minimum. Traffic intensity value varies from one BTS to another, as it is directly proportional to the number of GSM users that make or receive calls within a particular period of time. This paper proposes a new scheme that will consider the number of reserved channels within a particular BTS. The scheme also considers the following; available channels, offered traffic, new call arrival rate, handoff call arrival rate and mean call duration. The continuous-time single dimensional birth–death process is also adopted to model and analyze the performance of this scheme. Moreover, MATLAB was used for simulation of the analytical equations which were obtained from the proposed state transition diagram. However, analytical method and simulation were used in this research work.
