General Packet Radio Service (GPRS) is a packet-based mobile data service developed from GSM. It allows users to connect to the internet and transfer various types of data. A GPRS system consists of mobile devices, base stations, Serving GPRS Support Nodes (SGSNs), and Gateway GPRS Support Nodes (GGSNs). When a mobile activates an internet session, the base station notifies the SGSN, which sets up a packet tunnel with the GGSN using GPRS Tunneling Protocol (GTP). GPRS enables various applications like email, location-based services, e-commerce, and advertising. It provides benefits like mobility, immediacy, and localization of services.

2. 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.

A GPRS system consists of several network nodes including mobiles,

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.

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.

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.

14. 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.
