Data split and its effect on optimizing the database access time in mobile networks

الملخص EN

In this paper, we present a method that reduces access time to subscriber database in mobile networks.

At first, we assume a model to study the mathematical analysis about database and then we will show that this method can optimize the access time to database.

So, we analyze related concepts and present an analytical model to formulate service time for a database.

Also, we have studied and analyzed the effect of environment on the access time to database which is reviewed here.

The environment is mobile network and the database is a mobile system database.

Mobile network has some of special parameters which define both the rate and type of queries to database.

We have analyzed environment parameters and formulated the access time to database based on them.

Our method is data split.

Compared to flatly storing of data, this method is influenced by the new environment parameters.

These parameters include rate of access to split parts, split ratio of data and etc.

We formulated our method and showed reduction of access time.

Furthermore, we present some diagrams which are showing the access time versus split ratio.

These diagrams also are showing conditions and limitations which split ratio optimizes access time.

Finally, we have simulated our idea and observed that simulation results confirm theoretical results.
