Development of Switching Operations Techniques

Abstract

The purpose of this thesis is to investigate circuit switching techniques, packet switching techniques, GSM, GPRS and UMTS. The thesis includes the introduction to these techniques and the types of switching son recent and future networks. This is followed by making simulations for call scenarios using more than one network. In this respect five samples for scenarios have been taken, leading to full explanation of the messages between the elements .The final chapter embodies conclusion and recommendations for circuit switching and packet switching.
