COMPUTER NETWORKING

Detailed explanation-1: -The GSM architecture consists of three major interconnected subsystems that interact with themselves and with users through certain network interface. The subsystems are Base Station Subsystem (BSS), Network Switching Subsystem (NSS) and Operational Support Subsystem (OSS).

Detailed explanation-2: -The GSM network has four separate parts that work together to function as a whole: the mobile device itself, the base station subsystem (BSS), the network switching subsystem (NSS) and the operation and support subsystem (OSS).

Detailed explanation-3: -All the user equipment such as a cell phone, SIM card…etc. and software needed for communication with a GSM network. The four main components in GSM mobile stations are: Mobile termination which handles functions such as radio transmission, speech encoding/decoding, error detection/correction, and access to the SIM.

Detailed explanation-4: -GSM-The Mobile Station The MS consists of the physical equipment, such as the radio transceiver, display and digital signal processors, and the SIM card. It provides the air interface to the user in GSM networks. As such, other services are also provided, which include − Voice teleservices. Data bearer services.
