GPRS: General Packet Radio Service is fully packet oriented, data
trasnmission technique.
Purpose of GPRS is to provide packe ttrasfer service to the user of Interet.
GSM System is authorised to allocate a time slot whichever is vacant in 8
time slots.

GPRS: General Packet Radio Service

General Packet Radio Service (GPRS) is a packet switching system
that developed from GSM, GPRS can connect into Internet, it can
provide abundant of data transfer transaction, such as text, audio,
picture and so on.

A GPRS system consists of several network nodes including mobiles,
base station system, serving GPRS service node (SGSN) and gateway
GPRS service node (GGSN).

picture and so on.
When the mobile activates an Internet protocol (IP) packet data
session, the base station notiﬁes its SGSN. The SGSN activates the
session, called a packet data protocol (PDP) context, with the GGSN.

When the mobile activates an Internet protocol (IP) packet data
session, the base station notiﬁes its SGSN. The SGSN activates the
session, called a packet data protocol (PDP) context, with the GGSN.
When the GGSN acknowledges successful context creation, an IP
tunnel using the GPRS tunneling protocol (GTP) is created between
the SGSN and GGSN. The tunnel ID (TID) is tied to that mobile’s
context at both the GGSN and the SGSN.

SNDCP: Sub Network Dependent Convergence Protocol interface
between IP/X.25 and GPRS Speciﬁc Logical Link Control.

RLC/MAC block is the basic transport unit on air interface. Used to
carry data and Mac Signaling.

BSSGP is a protocol used to exchange information between two
GPRS entities viz. BSS and SGSN.

GPRS has opened a wide range of unique services to the mobile
wireless subscriber. Some of the characteristics that have opened a
market full of enhanced value services to the users. Below are some of
the characteristics:

some of the characteristics:
Mobility - The ability to maintain constant voice and data
communications while on the move.
Immediacy - Allows subscribers to obtain connectivity when needed,
regardless of location and without a lengthy login session.
Localization - Allows subscribers to obtain information relevant to
their current location.

Broad level, applications are divided into either
Carporation or Consumer
Communications - E-mail, fax, unified messaging and
intranet/internet access, etc.
Value-added services - Information services and games, etc.
E-commerce - Retail, ticket purchasing, banking and financial
trading,
Location-based applications - Navigation, traffic conditions,
airline/rail schedules and location finder, etc.
Vertical applications - Freight delivery, fleet management and
sales-force automation.
Advertising - Advertising may be location sensitive. For example, a
user entering a mall can receive advertisements specific to the stores
in that mall.
