What are the functions of GGSN of a GPRS network?

The GGSN, sometimes known as a wireless router, works in tandem with the Serving GPRS Support Node (SGSN) to keep mobile users connected to the Internet and IP-based applications. The GGSN converts incoming data traffic from mobile users (via the SGSN) and forwards it to the relevant network, and vice versa.

What are the functions of GGSN of a GPRS network *?

The GGSN is responsible for IP address assignment and is the default router for the connected user equipment (UE). The GGSN also performs authentication and charging functions. Other functions include subscriber screening, IP pool management and address mapping, QoS and PDP context enforcement.

What are the functions of SGSN in a GPRS architecture?

3.3. 1 Serving GPRS support node. The role of SGSN is equivalent to that of MSC/VLR in the current GSM network. SGSN connects BSS to GSGN, which provides ciphering, mobility management (e.g., inter‐SGSN routing area update and inter‐PLMN roaming), charging and statistics collection (i.e., support of billing records).

What is the difference between GGSN and SGSN?

To summarise; SGSN stands for Serving GPRS Support Node and is a network entity that provides the packet-switched capability to mobile networks. GGSN stands for Gateway GPRS Support Node and is a gateway situated between SGSN and external data networks.

What is GPRS function?

General Packet Radio Service (GPRS) is the mobile data system behind 2G — and some 3G — communication services. While GPRS is no longer in use for phones operating with 4G service, you can turn on the service on your Android cellphone running on 2G or 3G.

What is GPRS and how it works?

General Packet Radio Service (GPRS) is a packet oriented mobile data standard on the 2G and 3G cellular communication network’s global system for mobile communications (GSM). … It provides moderate-speed data transfer, by using unused time division multiple access (TDMA) channels in, for example, the GSM system.

What is Sgsn in LTE?

The Serving GPRS Support Node (SGSN) is a main component of the GPRS network, which handles all packet switched data within the network, e.g. the mobility management and authentication of the users. The SGSN performs the same functions as the MSC for voice traffic. The SGSN and the MSC are often co-located.

What is GPRS call type?

The General Packet Radio Service (GPRS) is an enhancement to the existing GSM network infrastructure and provides a connectionless packet data service. The same cellular base-stations that support voice calls are used to support GPRS and as a consequence GPRS can be used wherever it is possible to make a voice call.

What is GPRS and its architecture?

Advertisements. GPRS architecture works on the same procedure like GSM network, but, has additional entities that allow packet data transmission. This data network overlaps a second-generation GSM network providing packet data transport at the rates from 9.6 to 171 kbps.

What are the three main parts of a GSM architecture or 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 does Sgsn mean?

SGSN (Serving GPRS Support Node) Part of the GPRS infrastructure, the SGSN provides switching functionality, security and authentication via the HLR for GPRS users.

What is Sgsn MME?

The MME is the termination point in the network for ciphering/integrity protection for NAS signaling and handles the security key management. … The MME also provides the control plane function for mobility between LTE and 2G/3G access networks with the S3 interface terminating at the MME from the SGSN.

What is GSM architecture?

The GSM system architecture contains a variety of different elements, and is often termed the core network. It is essentially a data network with a various entities that provide the main control and interfacing for the whole mobile network.
