SYSTEM AND METHOD FOR PERCEPTUAL QOS-BASED CALL ADMISSION FOR VOIP, VOIPOW, AND CDMA SYSTEMS

摘要

ABSTRACT A method and system that utilize perceptual quality of service (QoS) metrics to determine whether to admit new calls onto a VoIP network is described. Perceptual QoS metrics are generated at a communications device, such as a telephone, that represent the measurement of perceptible variations in the quality level of a voice signal, or audio and video signal received at the communications device. A call admission threshold is generated from the perceptual QoS metrics for each node in the network that has communications devices attached thereto. When a request to admit a new call on the network through a node is received, the call admission threshold is compared with a priority value associated with the request to determine whether to admit the new call onto the network.
