Key Network
Features of GPRS
Packet Switching
GPRS involves overlaying a packet based air interface
on the existing circuit switched GSM network. This gives the user
an option to use a packet-based data service. To supplement a
circuit switched network architecture with packet switching is
quite a major upgrade. When the recipient empties the bag with
all the pieces, they are reassembled to form the original image.
All the pieces are all related and fit together,GPRS should improve
the peak time capacity of a GSM network since it simultaneously:
- Allocates scarce radio resources more
efficiently by supporting virtual connectivity
- Migrates traffic that was previously sent
using Circuit Switched Data to GPRS instead, and
- Reduces SMS Center and signaling channel loading
by migrating some traffic that previously was sent using SMS
to GPRS instead using the GPRS/ SMS interconnect that is supported
by the GPRS standards
Internet Aware
For the first time, GPRS fully enables Mobile
Internet functionality by allowing interworking between the existing
Internet and the new GPRS network. Any service that is used over
the fixed Internet today- File Transfer Protocol (FTP), web browsing,
chat, email, telnet will be as available over the mobile network
because of GPRS. In fact, many network operators are considering
the opportunity to use GPRS to help become wireless Internet Service
Providers in their own right
Supports TDMA and GSM
The IS-136 Time Division Multiple Access (TDMA) standard, popular
in North and South America, will also support GPRS.
