Using a Novel Efficient Location Management Approach in Cellular Networks
When a mobile terminal enters a new location area (LA), it always updates its current location information to its Home Location Register (HLR), when a call arrives, the system will page the mobile terminal (MT) based on its most recent updating. If location update (LU) frequency increases, the update cost increases. Decreasing location update would make the paging cost increases. In this paper, we propose an intelligent approach, it is an integrated location management scheme that combines Rule Base Paging Scheme (RBPS) and Traveling Salesman Mobility (TSM) model scheme. It applies an intelligent paging scheme with movement based LU strategy to resolve the total cost which is comprised of paging cost and LU cost. Also, it attempts to resolve the issue of inherent tradeoff between the paging cost and LU cost in location management. Analytical results show that proposed integrated new scheme, it does reduce the total cost for location management compared to the previous scheme, and obtain the better performance.
