Abstract

This paper studies the radio resource allocation for GPRS (General Packet Radio Service) and GSM (Global Systems for Mobile communications) on downlink traffic. We proposed an allocation strategy with partial time-slot sharing and complete radio-block sharing simultaneously. The radio-block based allocation strategy can characterize the practical multiplexing scheme for GPRS. We assumed that the system supports two classes of GPRS mobile terminals with different bandwidth requirements. We also assumed that the system can handle both new call and handover call for GSM requests. By both theoretical analysis and through computer simulation, the result showed that the proposed time-slot and radio-block based resource allocation strategy offers high utilization as well as low blocking probability to GPRS users under various traffic loadings.
