Differentiated Services in the GPRS Wireless Access Environment

The General Packet Radio Service extends the existing GSM mobile communications technology by providing packet switching and higher data rates in order to efficiently access IP-based services in the Internet. Even though Quality-of-Service notions and parameters are included in the GPRS specification, no realization path for Quality-of-Service support has been proposed. In this paper we adapt the Differentiated Services framework and apply it over the GPRS air interface in order to provide various levels of service differentiation and a true end-to-end application of the Internet Differentiated Services architecture.
