An adaptive location management scheme for mobile broadband cellular systems

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.
