Abstract :
The
GPRS specifications are written by the European Telecommunications Standard
Institute (ETSI), the European counterpart of the American National Standard
Institute (ANSI).
GPRS
stands for General Packet Radio System. GPRS
provides packet radio access for mobile Global System for Mobile Communications
(GSM) and time-division multiple access (TDMA) users.
GPRS
is important as a migration step toward third-generation (3G) networks and
allows network operators to implement an IP-based core architecture for data
applications, which will continue to be used and expanded for 3G services for
integrated voice and data applications.
GPRS
is a new bearer service for GSM that greatly improves and simplifies wireless
access to packet data networks, e.g., to the Internet. It applies a packet
radio principle to transfer user data packets in an efficient way between GSM
mobile stations and external packet data networks. Packets can be directly
routed from the GPRS mobile stations to packet switched networks.
GPRS enables a variety of new and unique
services to the mobile wireless subscriber. These mobile services have unique
characteristics that provide enhanced value to customers. These characteristics
include the following:
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.
