A GSM system manages communication between mobile stations, base stations, and switching systems. Every GSM radio channel is 200 kHz wide and is additionally divided into frames of 8-time slots. The global system for mobile communication (GSM) was first known as Groupe Special Mobile, which is the reason for the acronym.
Introduction to Wireless Communications and Networks.
GSM is superior at controlling circuit switching traffic and handles all the circuits in the network to control the traffic of the mobile devices. GPRS is superior at handling packets and even the data is shared in the form of packets. Therefore, the traffic is also controlled as packets and handles the packets in the network of GPRS. Global System for Mobile Communications (GSM) uses a combination of Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA). Frequency Division Multiple Access: It involves dividing a frequency band into multiple bands such that each sub-divided frequency band is allotted to a single subscriber.

The GPRS physical layer is based on that of the GSM (see Chapter 1). The access scheme is TDMA, with eight basic physical channels per carrier (TS 0 to 7). A physical channel uses a combination of frequency- and time-division multiplexing and is defined as a radio frequency channel and time slot pair. General Packet Radio Service (GPRS) leverages GSM network to build a packet based mobile cellular network.... gets around the problem of low data rate simply by bundling multiple time slots together instead of using single slot for transfer of data. GPRS supports packetized data transfers by introducing only minimal changes in core GSM network.
