What are the three parts of GSM architecture of structure?
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 is the role of BSS and NSS in GSM?
BSS handles traffic and signaling between a mobile phone and the network switching subsystem. BSS having two components BTS and BSC. NSS : NSS stands for Network and Switching Subsystem. NSS is the core network of GSM.
What is OSS in a GSM architecture?
30. Following is the figure, which shows how OMC system covers all the GSM elements. The OSS is the functional entity from which the network operator monitors and controls the system.
What is RSS in GSM?
Radio Substation (RSS) The RSS consists of the components that are necessary in order to allocate the radio resources to the individual subscribers. It principally consists of the mobile terminals (mobile phone or mobile station, MS) and the base station subsystem (BSS).
What is the function of BSS?
The base station subsystem (BSS) is the section of a traditional cellular telephone network which is responsible for handling traffic and signaling between a mobile phone and the network switching subsystem.
What are the elements of BSS?
The BSS is composed of two parts:
- The Base Transceiver Station (BTS)
- The Base Station Controller (BSC)
What is Gmsc in telecom?
The Gateway Mobile Switching Center (GMSC) is a type of Mobile Switching Center (MSC) that is used to route calls outside the mobile network. Mobile Switching Center Servers (MSC-S) provide control of high-capacity switching in mobile circuit core networks for operators to control services and switching.
What type of modulation is used in GSM?
Gaussian Minimum Shift Keying (GMSK)
The technology behind the Global System for Mobile communication (GSMTM) uses Gaussian Minimum Shift Keying (GMSK) modulation a variant of Phase Shift Keying (PSK) with Time Division Multiple Access (TDMA) signalling over Frequency Division Duplex (FDD) carriers.
What is MSC in GSM?
Description. The mobile switching center (MSC) is the primary service delivery node for GSM/CDMA, responsible for routing voice calls and SMS as well as other services (such as conference calls, FAX, and circuit-switched data).
What is Abis interface in GSM?
Abis interface This is a BSS internal interface linking the BSC and a BTS, and it has not been totally standardised. The Abis interface allows control of the radio equipment and radio frequency allocation in the BTS. A interface The A interface is used to provide communication between the BSS and the MSC.
What is BSS process?
BSS deals with the taking of orders, payment issues, revenues, etc. It supports four processes: product management, order management, revenue management and customer management.
What is difference between BSS and OSS?
Operation Support System (OSS), as name suggests, is a software tool that is generally used to organizations to manage their operation system or communication networks….Difference between OSS and BSS :
| OSS | BSS |
|---|---|
| OSS mainly focuses on network management. | BSS mainly focuses on all activities within organization. |
What is the difference between MSC and GMSC?
GMSC is used to link between PSTN network and cellular network. but MSC is the part of the cellular network and used to control its under BSCs and to update information of the mobiles.
What is base switching center?
Switching Center means a central communications hub that is responsible for routing packet traffic to and from Base Stations and/or Access Points and the Internet as necessary to carry out the mobile service within the Fields of Use and License-free Spectrum.
What is BTS BSC and MSC?
The BTS (Base Transceiver Station) is controlling the radio transmission and the interface to the mobile phones. Several BTS connect to BSC stations (Base Station Controller), while the BSC are connected to the MSC (Mobile Switching Center).
