A New Location Management Scheme for the Next-Generation Mobile Cellular Networks

摘要

This paper proposes a location management scheme—combining dynamic location update scheme with static one for the next-generation mobile cellular networks. In the proposed strategy, instead of adopting dynamic location management for all mobile users, classifying them into DLMU(Dynamic Location Management User) and SLMU(Static Location Management User) by a CMR(Call-to- Mobility-Ratio) threshold. Compared with the conventional location update scheme, this strategy can make good use of the dynamic, movement-based location update scheme employed in this paper. Moreover, this paper analyzes how to choose the CMR threshold by simulation. As for the next-generation mobile cellular networks, this proposed scheme can be implemented to reduce the signaling cost evidently, for its facility and feasibility compared with the conventional dynamic location management.
