A built-in memory model for reducing location update cost in mobile wireless networks

摘要

This paper proposes a new model for reducing the signaling and database access traffic due to users' mobility in wireless networks. It requires a small built-in memory in the Mobile Unit (MU) that stores the same location data (MU's location area address) as in the Home Location Register (HLR). When the MU changes its Location Area (LA), it queries the LA whose address is stored in the MU built-in Memory to create a pointer between that LA and the MU's current LA.
