Guidelines to the Problem of Location Management and Database Architecture for the Next Generation Mobile Networks

TL;DR

This paper proposes new guidelines and architectures for location management in next-generation mobile networks, aiming to reduce delays and improve database efficiency amid increasing user mobility.

Contribution

It introduces a multitree distributed database, high throughput indexing, and memory-oriented organization, along with protocols for roaming and neighbor discovery, to enhance location management.

Findings

Analytic models evaluate efficiency improvements.

Guidelines reduce end-to-end delays.

Distributed database architecture supports scalability.

Abstract

In near future, anticipated large number of mobile users may introduce very large centralized databases and increase end-to-end delays in location registration and call delivery on HLR-VLR database and will become infeasible. After observing several problems we propose some guidelines. Multitree distributed database, high throughput index structure, memory oriented database organization are used. Location management guidelines for moving user in overlapping network, neighbor discovery protocol (NDP), and global roaming rule are adopted. Analytic model and examples are presented to evaluate the efficiency of proposed guidelines.
