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.
