Mobile location management strategy with implicit location registration

We propose a new location management strategy by introducing the concept of implicit location registration. Implicit location registration is triggered whenever a transaction occurs between the backbone network and a mobile terminal. The mobile's most recently notified cell and its neighboring cells are paged to locate a mobile. It is shown that the proposed strategy has the lower paging cost than the simultaneous paging scheme. In addition, the proposed strategy can further reduce the paging cost when the terminal mobility is low and when there are many transactions between the backbone network and mobile terminals.
