What are the functionality of SGSN and GGSN?

SGSN provides the packet-switched capability to GSM and UMTS networks to enable mobile data (mobile internet). GGSN converts that data into a suitable protocol format (e.g. IP) before sending it over to the destination external network.

What are the functions of SGSN?

A SGSN is responsible for the delivery of data packets from and to the mobile stations within its geographical service area. Its tasks include packet routing and transfer, mobility management (attach/detach and location management), logical link management, and authentication and charging functions.

What are the functions of GGSN and SGSN in GPRS?

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 functionalities offered by 3G GGSN in UMTS core network architecture?

The 3G-GGSN provides the following functions: Gateway-specific access methods to intranet (e.g. PPP termination) Initiate mobile terminate Route Mobile Terminated packets User data screening/security can include subscription based, user controlled, or network controlled screening.

What are the functions of MSC in CDMA architecture?

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 MSC Telecom?

Mobile Switching Centre A Mobile Switching Center (MSC) is a core part of the GSM/CDMA network system. It acts as a control center of a Network Switching Subsystem (NSS). The MSC connects calls between subscribers by switching the digital voice packets between network paths.

What is the functionality of GGSN?

The gateway GPRS support node (GGSN) converts the incoming data traffic coming from the mobile users through the Service gateway GPRS support node (SGSN) and forwards it to the relevant network, and vice versa. The GGSN and the SGSN together form the GPRS support nodes (GSN).

What are the features of UMTS?

Features of UMTS It gives transmission of content, digitized voice, video and multimedia. It gives tall transmission capacity to portable operators. It gives a tall information rate of 2Mbps. For High-Speed Downlink Parcel Get to (HSDPA) handsets, the data-rate is as tall as 7.2 Mbps within the downlink connection.

What are the functions of SGSN in a GPRS architecture?

The SGSN or Serving GPRS Support Node element of the GPRS network provides a number of takes focussed on the IP elements of the overall system. It provides a variety of services to the mobiles: Packet routing and transfer. Mobility management.
