GPRS is a packet service for GSM

Specially designed to work within existing network

Co-exists with existing circuit switched services

Packet data transmission all the way to the user

Interworking with data networks (e.g. IP)

In circuit-switching, resources (e.g. a channel) are allocated to user for duration of connection

Inefficient use of resources

User pays for the duration of connection

Reserved Bandwidth but low data rate

Costly for data services

In packet-switching, resources are allocated to user only for the time it takes to send each packet

A channel can serve many users

Shared Bandwidth and Comparatively high data rates

User pays by the packet

Ideal for bursty data connections

Basic knowledge.. nice short note..
