In this paper, we propose and evaluate under realistic mobility patters an adaptive location management strategy that jointly considers location update and paging. It requires little involvement of the terminal, and a non excessive computational load in the network. The location update scheme is based on the definition of an adaptive macro-location area, adapted to the mobility pattern of the terminals. In addition, we propose a sequential paging strategy that takes advantage of the multi-register in the macro-location area to characterize the residence probabilities in each location area of a generic macro area. Results show the viability of the proposal and its applicability to new packet-based broadband cellular systems.
