Abstract

The quality of service (QoS) limitation of Internet is major challenge for Voice over IP (VoIP). Delay jitter and packet loss are two essential problems which impair the communication quality. Conventional quality-driven QoS control methods usually use ITU-T E-Model to maximize the Mean Opinion Score (MOS) in terms of delay and loss. However, all these methods are devised only for narrowband speech codec and only suitable for random loss. The aim of this paper is to propose a new quality-driven QoS control method for AMR-WB (a wideband speech codec) in bursty loss condition. Experimental results show that the perceived speech quality is improved with the proposed method.
