The General Packet Radio Service is a packet data service for phase 2+ of Global System for Mobile Communications (GSM). It not only defines the packet-switched data service, but also tries to provide quality of service (QOS) guarantees on data flows. Scheduling is an important aspect in supporting of QOS and GPRS. In this paper, two scheduling algorithms, the Modified Earliest Deadline (MED) and Minimum Laxity threshold (MLT), have been elaborated. Both scheduling algorithms allow GPRS to attain high channel utilization, with MTL performing better than MED.
