Abstract

We propose a predictive scheme, where the MT stores only current day movement log and sends this log to MSC during off-peak hours. The MSC performs offline computation to find unique sub-patterns and hot cells from pattern logs. The hot cells are downloaded in the MT which sends an update when it leaves a hot cell thus enables the MSC to identify the sub-pattern to be followed next. On arrival of a call the MSC performs selective paging Analytical study shows the total location management cost using the proposed scheme is far better than distance-based location management scheme.
