N2 - Supporting QoS for VoIP is a topic that clearly remain of importance. Existing QoS mechanisms for voice over IP need to be adapted. This is essentially due to the high dynamicky and variability of subjective voice quality perception, particularly in some critical conditions (ex. mobile networks). In this paper, we present an architecture, called "MOSQoS", that integrates subjective voice quality assessment into a dynamic QoS loop control. This QoS loop control is based on a subjective and dynamic voice quality evaluation (MOS score). It maintains as constant as possible, a predefined target MOS score during the entire voice session. To achieve this approach, we implement "P-E-Model" for subjective voice quality evaluation and combine it with a signaling protocol to dynamically control and optimize network resources such as: queuing allocation and congestion thresholds. Tests and measures obtained through an implementation of the "MOSQoS" approach, show that results in terms of feasibility and performance, are globally satisfactory.
