  Abstract

In group location management, when a transportation system (TS) with multiple mobile subscribers (MSs) changes location area (LA), location management is performed by group location registration without individual location registrations of MSs. In previous works, although it is assumed that LAs in both individual and group location managements are the same, it is not appropriate to assume the same sized LAs since MSs in a TS have different characteristics from MSs which are not in a TS from the aspect of the speed and aggregate call arrival rates. Thus, in this paper, we propose an efficient location management scheme based on individual and group location managements with different sized LAs, and the performance of the proposed scheme is analyzed from the aspect of signaling cost at the wireless interface. Results reveal that the proposed scheme outperforms the conventional scheme by selecting an appropriate sized LA for group location management.
