Gsm network architecture

There were four main elements to the overall GSM architecture and these could often be further split.

Gsm network architecture

This tutorial section on GSM basics covers following sub topics: It is called 2G or Second Generation technology. It is developed to make use of same subscriber units or mobile phone terminals throughout the world. Following figure depicts complete GSM system network architecture.

SIM contains subscriber related all the information, network with which subscriber is subscribed with and encryption related information. The cell size is usually about m to about 35 km. BTS coverage is limited to this cell.

Like this many BTSs cover entire region. Network Subsystem NSS - This subsystem provides interface between cellular system and circuit switched telephone network i.

GSM - Architecture

NSS takes care of call processing functions such as call setup, switching, tear down and also hand over between BSCs. NSS takes care of security and authentication related functions. There are various network elements in this subsystem as mentioned in GSM network architecture above.

They are explained below. These are basically database elements. VLR- Visitor Location Register, it stores visitor subscriber related information about its facilities, the network it is subscribed to, and its home location and so on.

AUC- Authentication center, used to authenticate activities in the system.

Refer the links mentioned on the left side panel for the same.GSM Architecture. A GSM network consists of the following components: A Mobile Station: It is the mobile phone which consists of the transceiver, the display and the processor and is controlled by a SIM card operating over the network.

Base Station Subsystem. Global System for Mobile Communication Technology Mobile Device Investigations Program Technical Operations Division. DHS - FLETC GSM Architecture and Subsystems By standard the GSM network is divided into four (4) subsystems 1. The Base-Station Subsystem 2. The Network Subsystem.
