Improved Channel Allocation and RLC block scheduling for Downlink traffic in GPRS

Abstract

This paper investigates the Radio Resource Management (RRM) approaches for GSM/GPRS networks. The effort was put on Access Control(AC), Time-Slot (TS) allocation, and Radio Link Control (RLC) packet scheduling for down-link performance enhancement. A new credit-based algorithm was proposed and implemented in a system level simulator. The simulation results for overall cell throughput as well as throughput per user show an improvement for the proposed scheme in comparison to a Best Effort algorithm, in particular in high-load scenarios.
