Evaluation of a MAC protocol proposed for a general packet radio service in GSM
Goetz Brasche · 2002
One major issue of the phase 2+ development of the pan-European Global System for Mobile communications (GSM) is to specify a general packet radio service (GPRS). Such a service is necessary to be able to fulfil the increased user requirements for reasonable data services. In this paper, an overview about the overall GPRS concept, its architecture and service characteristics is given. In addition, a medium access control protocol that controls access of multiple mobile stations onto the radio channel is introduced and evaluated by simulation. The protocol is mainly characterized by dynamic bandwidth allocation and its multi-slot features. Finally, conclusions are drawn and further work items are discussed.
