Multi Tree Data Base Architecture for Location Tracking in Next Generation Mobile Network

The next-generation mobile network will support terminal mobility, personal mobility, and service provider portability, making global roaming seamless. A location-independent personal telecommunication number (PTN) scheme is conducive to implementing such a global mobile system. In this paper, firstly we propose multi tree database architecture consists of a number of database subsystems, each of which is a three-level t also proposes indexing schemes for each type of location databases and analyzes their efficiency and cost in terms of database access time and storage requirement. Tree structure and is connected to the others only through its root. Results have revealed that the proposed database architecture for location management can effectively support the anticipated high user density in the future mobile networks.
