GSM: Network Architecture The GSM technical specifications define the different entities that form the GSM network by defining their functions and interface requirements. The GSM network can be divided into four main parts: * The Mobile Station (MS). * The Base Station Subsystem (BSS). * The Network and Switching Subsystem (NSS). * The Operation and Support Subsystem (OSS). figure 1: Architecture of the GSM network Mobile Station A Mobile Station consists of two main

This paper deals with the design & development of a theft control system for an automobile‚ which is being used to prevent/control the theft of a vehicle. The developed system makes use of an embedded system based on GSM technology. The designed & developed system is installed in the vehicle. An interfacing mobile is also connected to the microcontroller‚ which is in turn‚ connected to the engine. Once‚ the vehicle is being stolen‚ the information is being used by the vehicle owner for further processing

network record that the mobile station is powered on and is ready to make or receive calls. The location update procedure lets the network record which location the MS is now anchored. To proceed with those tasks the mobile station must make a service request to the network. 1. MS after dialing a number and press send key uses RACH to ask for a signaling channel. 2. The BSC allocates a signaling channel‚ using AGCH. 3. The MS sends a call setup request through SDCCH‚ to the MSC/VLR. Over

Global System for Mobile Communication (GSM) Definition Global system for mobile communication (GSM) is a globally accepted standard for digital cellular communication. GSM is the name of a standardization group established in 1982 to create a common European mobile telephone standard that would formulate specifications for a pan-European mobile cellular radio system operating at 900 MHz. It is estimated that many countries outside of Europe will join the GSM partnership. Overview This tutorial
