Considering some of the major challenges suffered by majority of the wireless communication network users and also the challenges being faced by the network providers in order to provide satisfactory quality of services that will meet the demand of their subscribers, there is a need for an implementation of a better call management scheme. This proposed scheme classified calls into two groups; short-calls and long-calls. Statistically, it has been found that over 65% of GSM users make calls that are less than or equal to 180s. Hence, this proposed scheme will give priority to short calls, and also adopt a relative probability factor (β) which will be used to allocate some percentage of the channels that were initially allocated to long calls whenever the long calls are minimal within the last interval being considered. This scheme tends to provide better utilisation of communication channels at all-time especially at peak periods. This paper considers the number of available channels, signal strength, short-call duration, long-call duration, call arrival rate and call service rate within the Base Transceiver Station (BTS).
