Abstract

This project consists in simulating the signaling between a mobile user and a landline user using SS7 protocol, which illustrate the calling process. The software known as OMNET + + , is a discrete network simulator, generally used to model the telecommunications traffic networks, protocols ,multiprocessors and distributed systems, that represent different types of network process. In the simulation process, mobile phones that are randomly picked, will be connected to the nearest Base Station (BTS) and communicate with a message which information will be shown in detail and send to the Central Base Station (BSC), it will arrive to the Mobile Switching Centre (MSC) and route to the SS7 network . In this network we are going to find Signaling Points (SP), which are: Service Switching Points (SSP), Signal Transfer Point (STP), Service Control Points (SCP), that enable communication in SS7 network, sending and receiving messages between signaling point, that are going to allow communication between calling and called subscriber.
