What are GPRS protocols?

What are GPRS protocols?

The GPRS protocol stack is a key element within the overall GPRS handset or base station. It enables the different functions to be split into different layers so that the correct priorities. The protocol stack enables the exchanges to take place in the required fashion and to be managed in an orderly fashion.

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 is the use of SGSN and GGSN?

SGSN and GGSN are the two core network elements of the general packet radio service which enables Internet to become mobile. It allows mobile users to access text based data services without continuously occupying a specific radio channel (which is not the case when you access voice channel).

What is the role of GR in GPRS?

The Gr interface is a GPRS interface which is located between the SGSN (Serving GPRS Support Node) and the HLR (Home Location Register).

What are the applications of GPRS?

Nowadays GPRS applications like chat, multimedia message, networks, personal information management, vehicle positioning, location-based services, and telematics.

What are GSM protocols?

GSM architecture is a layered model that is designed to allow communications between two different systems. The lower layers assure the services of the upper-layer protocols. Each layer passes suitable notifications to ensure the transmitted data has been formatted, transmitted, and received accurately.

What are the characteristics of GPRS?

2.5 GPRS characteristics [1]:

  • transmission modes: send and receive data in packet transfer mode; cost effective and efficient use of network resources.
  • traffic characteristics: intermittent, bursty data transmissions; frequent transmissions of small volumes of data; infrequent transmission of large volumes of data.

What is difference between GGSN and SGSN?

SGSN and GGSN are used for connecting our cell phones to mobile internet through GPRS, EDGE, HSPA and HSPA+ technologies in 2G GSM and 3G UMTS networks. SGSN is the main node that performs packet-switching functions, whereas GGSN is more of a router that connects SGSN to the external data networks.

What is Gn and Gi interface?

Gn/Gp interface, is the interface between the SGSNs and the GGSNs. ‘Gn interface’ is the interface between the SGSNs and the GGSNs when they exist within the same mobile network. Gn Interface. Learn Mobile Packet Core Network in 5 Hours. Online Course.

What are the limitations of GPRS?


  • Limited Cell Capacity for All Users: GPRS does impact a network’s existing cell capacity.
  • Speeds Much Lower in Reality.
  • Achieving the theoretical maximum GPRS data transmission speed of 172.2 kbps would require a single user taking over all eight timeslots without any error protection.
