A simple implementation of distance-based location updates

Recent studies suggest that distance-based location update strategies combined with sequential paging could outperform other location management schemes in terms of saving radio resources. A problem has been though that distance-based strategies are in general difficult to implement. This paper proposes a simple implementation of distance-based location updates. The scheme is based on using neighbor cell information which is normally broadcast on common control channels to enable cell selection of mobile stations. The computational load placed on the mobile stations is small. A limitation of the scheme is that only distance-based strategies with small thresholds are implemented.
