ABSTRACT
The report presents the GSM, the Global System for Mobile communications, is a digital cellular communications system which has rapidly gained acceptance and market share worldwide, although it was initially developed in a European context. In addition to digital transmission, GSM incorporates many advanced services and features, including ISDN compatibility and worldwide roaming in other GSM networks. The advanced services and architecture of GSM have made it a model for future third-generation cellular systems, such as UMTS. This will give an overview of the services offered by GSM, the system architecture, the radio transmission structure, and the signaling functional architecture.
The purpose of the latest technology expand is for the development of available system to fit the current time flow, to simplify the procedure and beside that are harmless to consumer.. The purpose of developing this system is to give more convenient to both side that will be using this system. SMS is the best medium to give a short note. This technology used to complete the system development.
This project report includes all the details development of GSM which is the first step towards a true personal communication system that will allow communication anywhere, anytime, and with anyone. The functional architecture of GSM, employing intelligent networking principles, and its ideology, which provides enough standardization to ensure compatibility, but still allows manufacturers and operators freedom, has been widely adopted in the is the first step towards a true personal communication system that will allow communication anywhere, anytime, and with anyone.

MOBILE COMMUNICATION
Basic concepts : A connection between two people − a caller and the called person − is the basic service of all telephone networks. To provide this service, the network must be able to set up and maintain a call, which involves a number of tasks: identifying the called person, determining the location, routing the call, and ensuring that the connection is sustained as long as the conversation lasts. After the transaction, the connection is terminated and (normally) the calling user is charged for the service he has used.
In a fixed telephone network, providing and managing connections is a relatively easy process, because telephones are connected by wires to the network and their location is permanent from the networks’ point of view. In a mobile network, however, the establishment of a call is a far more complex task, as the wireless (radio) connection enables the users to move at their own free will − providing they stay within the network's service area. In practice, the network has to find solutions to three problems before it can even set up a call:
INTRODUCTION:
The global System for Mobile Communications, GSM is a digital cellular communications system. It was developed in order to create a common European mobile telephone standard but it has been rapidly accepted worldwide. GSM is designed to provide a comprehensive range of services and features to the users not available on analogue cellular networks and in many cases very much in advance of the old public switched telephone network (PSTN). In addition to digital transmission, GSM incorporates many advanced services and features like worldwide roaming in other GSM networks.
9The idea of cell-based mobile radio systems appeared at Bell Laboratories (in USA) in the early 1970s. However, mobile cellular systems were not introduced for commercial use until the 1980s. During the early 1980s, analog cellular telephone systems experienced a very rapid growth in Europe, particularly in Scandinavia and the United Kingdom, but also in France and Germany. Each country developed its own system, which was incompatible with everyone else's in equipment and operation. But in the beginnings of cellular systems
GSM NETWORK ELEMENTS
GSM stands for Global System for Mobile communication & 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. GSM provides recommendations, not requirements. The GSM specifications define the functions and interface requirements in detail but do not address the hardware. The reason for this is to limit the designers as little as possible but still to make it possible for the operators to buy equipment from different suppliers.
Mobile Station (MS)
In GSM, the mobile phone is called Mobile Station (MS). The MS is a combination of terminal equipment and subscriber data. The terminal equipment as such is called ME (Mobile Equipment) and the subscriber's data is stored in a separate module called SIM (Subscriber Identity Module).
Therefore, ME + SIM = MS.
From the user’s point of view, the SIM is certainly the best-known database used in a GSM network. The SIM is a small memory device mounted on a card and contains user-specific identification. The SIM card can be taken out of one mobile equipment and inserted into another. In the GSM network, the SIM card identifies the user − just like a traveler uses a passport to identify himself.
