Location management scheme tracking the location information of a mobile user is required to deliver the incoming calls since the latest wireless communication networks allow dynamic relocation of mobile terminals. In this paper, we propose a mobile locality based location management scheme using the mobility information of mobile users to provide an efficient location management mechanism. In our scheme, the location registration process caches the location information of visited cells to reduce duplicated registrations of mobile users. The paging process exploits the locality of mobile user’s moving behavior patterns to predict the possible paging area. So, it can reduce the paging cost in a location search procedure. The performance of the proposed location management scheme is to be evaluated by an analytical model, and is compared with that of a Dynamic Location Management Scheme.
