What is 3G network architecture?
3G UMTS Core Network. The 3G UMTS core network architecture is a migration of that used for GSM with further elements overlaid to enable the additional functionality demanded by UMTS. Packet switched elements: These network entities are designed to carry packet data.
What are the parts of a 3G network architecture?
There are three major parts to a 3G mobile network:
- A Radio Access Network (RAN). This is a hierarchical arrangement of cell towers and base stations.
- A core network (usually IP) tying the RAN to the 3G service network.
- A service network reached through the core network.
How does 3G network work?
The 3G services work using a “cellular” based technology; the signals are passed from phone tower to phone tower, and then the tower nearest the phone passes the signal to it. It also means there can be dips in service as you move around, as the signal switches from tower to tower and as you move too far from a tower.
What is UMTS architecture?
UMTS system uses the same core network as the GPRS and uses entirely new radio interface. The new radio network in UMTS is called UTRAN (UMTS Terrestrial Radio Access Network) and is connected to the core network (CN) of GPRS via Iu interface. The mobile terminal in UMTS is called User Equipment (UE). …
Which technology is used in 3G?
In Asia, Europe, Canada, and the US, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks.
What is 3G UMTS?
UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps). UMTS is based on the Global System for Mobile (GSM) communication standard.
What are the three main parts of GSM 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 is GSM and GSM architecture?
GSM is an open and digital cellular technology used for mobile communication. It uses 4 different frequency bands of 850 MHz, 900 MHz, 1800 MHz and 1900 MHz . This article includes all the concepts of GSM architecture and how it works. GSM is having 4 different sizes of cells are used in GSM : Attention reader!
