Introduction to Distributed Database Architecture for Global Roaming in Next Generation Mobile Network  Project:

The main objective of this paper is to give idea of global roaming in mobile network. As usage of mobile phones are increasing day to day , the subscriber of a particular network expect more services from provider. For example, if user moves from one location to another he can’t change the personal telecommunication number every time. Portability is one of the main services which user expects. Hence, Global roaming came into existence. Global roaming is defined as the basic service which supports terminal mobility, personal mobility, and service provider.    

Brief into Distributed Database Architecture for Global Roaming in  Next –Generation Mobile

In global roaming, the database which is used is wireless. Since it is wireless each and every region will have a node and tower. The node in the region stores the information.  Whenever the subscriber moves from one region to another region  mobile switching station will update the location information, this allows the user to receive services without any interruption.

This database consists of  index file and a direct file. The index file is used to determine the database access time . Direct file is considered as perfect hashing due to its collision-free. This is used in DB0 also because it can give fast response and implementation is easy.


The database architecture used in this is scalable, robust and easy to expand than other conventional networks. By using this network there will not be be any interruption for the user while using the service.
