Voice Adaptation for Wireless Communication

摘要

A system and method for optimizing voice communications in a wireless network including an AP having a message waiting time that provides proper QoS while losing minimal communication bandwidth. The QoS may be responsive to the amount of user traffic in both the AP and neighboring APs. The method may include setting parameters for each level of QoS in response to a measure of the degree of contention for that level of QoS, and in response to a measure of the degree of contention for those levels of QoS with higher priority, and setting waiting time parameters in response to a stochastic model of contention at each level of QoS. Operational parameters might include contention window time, AIFS time, and back-off value(s), and might be modified in response to message QoS.

1. A method in an access point of a wireless communication system, comprising:
determining a type for traffic received at the access point; queuing the traffic at the access point responsive to the type of traffic; receiving measurements for each type of external traffic heard at the access point, the traffic associated with at least one external access point and at least one a wireless device; determining one or more contention parameters responsive to the measurements for each type of external traffic and a quality of service associated with the type of traffic; and contending for communication bandwidth for each type of traffic in response to the one or more contention parameters.
