General Packet Radio Service (GPRS) is a packet oriented Mobile Data Service available to users of Global System for Mobile Communications (GSM) and IS-136 mobile phones. It provides data rates from 56 up to 114 kbit/s. Architecture of both GSM & GPRS Network is shown above. The basic differences of GPRS and GSM are Circuit Switched and Packet Swiched (shown bellow).
packet switched
Data as a packet switched and voice as a circuit switched is using the same resource of several equipments in the GSM Network. From Mobile Station (MS) or Mobile Equipment (ME) to Base Transceiver Station is using one network. Detail picture which describe this statement is shown bellow

Why GPRS is needed?
1. GPRS make possible to get always connected connection
2. GPRS is charged by bit transfered
3. GPRS give a lower prices rather than High Speed Circuit Data
4. Higher Speed
5. Faster Session Start
The logical structure for GPRS Network is shown here
