What is GSM explain its architecture?
What is GSM explain its architecture?
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).
What are the main parts of GSM architecture?
GSM – Architecture
- The Mobile Station (MS)
- The Base Station Subsystem (BSS)
- The Network Switching Subsystem (NSS)
- The Operation Support Subsystem (OSS)
How does a GSM modem work?
A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
What are the main network elements of GSM system?
The GSM network is divided into three major systems: the switching system (SS), the base station system (BSS), and the operation and support system (OSS). The basic GSM network elements are shown in Figure 2. The switching system (SS) is responsible for performing call processing and subscriber-related functions.
What is 2G architecture?
A. 0-9. The infrastructure of 2G and 3G cellular networks are similar. They comprise an air interface between the user’s mobile device and the base station and two core networks; one for circuit-switched voice and another for packet-switched data.
What are GSM standards?
The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.
What is the function of NSS in GSM?
The Network switching system (NSS), the main part of which is the Mobile Switching Center (MSC), performs the switching of calls between the mobile and other fixed or mobile network users, as well as the management of mobile services such as authentication.
What is the primary goal of GSM?
The GSM system was designed as a second generation (2G) cellular phone technology. One of the basic aims was to provide a system that would enable greater capacity to be achieved than the previous first generation analogue systems. GSM achieved this by using a digital TDMA (time division multiple access approach).
What is 2G 3G 4G architecture?
They comprise an air interface between the user’s mobile device and the base station and two core networks; one for circuit-switched voice and another for packet-switched data. In the subsequent 4G/LTE architecture, voice and data are both based on IP packets.
What is the architecture of GSM?
The GSM architecture is divided into Radio Subsystem, Network and Switching Subsystem and the Operation Subsystem. The radio sub system consists of the Mobile Station and Base Station Subsystem. The mobile station is generally the mobile phone which consists of a transceiver, display and a processor.
What is the GSM network architecture of 2G?
The GSM network architecture of 2G mainly follows a logical technique of operation. This is very simple as compared with present architectures of mobile phone network which utilize software-defined units to allow extremely supple operation.
What are the components of GSM technology?
GSM Technology Architecture 1 Network Switching Subsystem (NSS) In GSM system architecture, it includes different elements, which are frequently known as the core system/network. 2 Base Station Subsystem (BSS) It acts as an interface between the mobile station and the network subsystem. 3 Mobile Station.
What is a GSM modem and how does it work?
Although the confidentiality of a call and secrecy of the GSM subscriber is just ensured on the radio channel, this is a major step in achieving end-to-end security. A GSM modem is a device that can be either a mobile phone or a modem device that can be used to make a computer or any other processor communicate over a network.
