Telecommunication B.V.M. Engineering College V.V.Nagar ‚ Anand ‚ India darshan242@yahoo.co.in Abstract—GSM network is widely used today whether it is for calling or SMS. Also some of the places needs urgent notices like in college‚ railway stations share-market ‚ and this notice should be in real-time ‚ so we need a real-time notice. This project is our experiment to give a start to the era of real-time noticing. This project is about writing the message which is to be displayed in mobile and send it as SMS to other

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

Network and Cell Information Acquisition When a mobile station is successful in synchronizations it reads four time-slot long Broadcast Control CHannel (BCCH) for the system information. This channel has a specific time-slot relative to the FCCH/SCH channels. The information in the BCCH channel includes: Location Area ID (LAI) o Mobile Country Code (MCC) o Mobile Network Code (MNC) o Location Area Code (LAC) Cell ID (CID) BCCH Allocation List (BA list) – a list of neighboring cells’
