This paper presents a new location management scheme that integrates two key ideas, namely, (i) Subscriber Movement Profile (SMP) based on spatial and temporal locality of the movement of a mobile terminal and (ii) localized updates known as Time-bound Self Purging Indicators (TSPI) generated by a probabilistic approach when a mobile terminal does not adhere to registered profile. The SMP registered by a mobile host is used to predict its cell location based on time specific movement history. The transient deviations from the registered SMP are handled efficiently by TSPIs using a Regional Route Map (RRM). © Springer-Verlag Berlin Heidelberg 2005.
