VIGIE : A learning tool for cellular air interfaces (GSM, GPRS, UMTS, WiFi)

Abstract : One of the difficulties encountered in the teaching of mobile radio networks is to present in a simple way the interaction and the sequencing of various tasks, which must be carried out by the mobile station (MS) and the network over the air interface. The comprehension of these processes is facilitated when they are presented in a visual form that can be understood in real-time, when the common MS-Network tasks such as voice call (MS oriented or MS terminated), short message service (SMS) are going on. This paper describes the architecture of the VIGIE (Visualisation and Interpretation of GSM/GPRS for Institutes & Ecole) software, developed in Java to display the exchanges of these tasks between the MS and the network. The uniqueness in the architecture of this tool is revealed in terms of its modularity. Finally the current work done on the development of the General Packet Radio Service (GPRS) logical screen and the Downlink Signaling Counter (DSC) graphical screen are described.
