Minimising network cost by employing sliding window method at mobile switching centres in GSM network

The cost effort of a global system for mobile communications (GSM) network is to be minimised for meeting effectively and efficiently the service requirements of ever increasing mobile subscriber's base. The period of temporary storage of subscribers' profiles in visitor location register (VLR) at a mobile switching centre (MSC) affects the cost of GSM network. This research study proposes a sliding window method for determining the storage period of profiles in VLR that minimises the network cost of GSM network. Further, this study examined and evaluated the computational efforts on proposed method. The proposed method proves to be better than the reported set intersection method.
