Abstract: The throughput of a Global System for Mobile Communications (GSM) network is to be maximised for effectively and efficiently meeting the service requirements of the ever-increasing mobile subscriber base. The period of temporary storage of subscribers' profiles in the Visitor Location Register (VLR) at a Mobile Switching Centre (MSC) affects the throughput of a GSM network. This research study proposes a sliding window method for determining the storage period of profiles in the VLR, and the principle of optimisation for such a policy is to maximise the throughput and minimise the call set-up time in a GSM network.
Keywords: global system for mobile communications; visitor location register; mobile switching centre; sliding window size; optimisation; GSM networks; network throughput; profile storage; call setup times.
