摘要：

For almost three years the European Telecommunications Standards Institute (ETSI) has been working on the specification of general packet radio service (GPRS) for the Global System for Mobile Communications (GSM). In the course of 1997 standardization will come to an end, and a first introduction of GPRS by a service provider or network operator is likely to take place in 1999. The new service will accommodate data connections with variable bit rates and high bandwidth efficiency, and thus offers the possibility to attract a wide range of new applications to GSM networks. In this article possible applications and elementary concepts and service characteristics of GPRS will be explained in detail. Furthermore, a medium access control protocol that conforms to the draft standard proposal for the GPRS air interface will be introduced and analyzed. Thereafter, the simulation model will be described and simulation results will be presented. The performance analysis carried out shows reasonable performance even under high load conditions.
