THROUGHPUT ENHANCEMENT USING ADAPTIVE DELAY BARRIER FUNCTION OVER HSDPA SYSTEM IN MIXED TRAFFIC SCENARIOS

Yong-Seok Kim

Abstract

In this paper, we consider a method to enhance the throughput of HSDPA system in the mixed traffic scenario. Adaptive delay barrier (DB) function and adaptation method are proposed to maximize throughput of best-effort (BE) traffic with satisfying the delay latency of voice over internet protocol (VoIP) service. Moreover, in order to guarantee quality-of-service (QoS) for the mixed traffics, a design of modified scheduling scheme is provided in this paper. Simulation results show that the throughput of BE traffic service with a channel-adaptive DB function increases up to 30%, compared with the conventional scheme, without degrading the capacity of VoIP service over HSDPA system.
