Call parameter selection and self-enforced admission control for optimizing voice over internet protocol performance in wireless networks

摘要

A method for transmitting voice data traffic over a wireless medium using a decision process for the admission of a voice call, such as a call voice over Internet Protocol (VoIP) over a wireless local area network (WLAN). Admission of the call through the network is based upon the priority level of the call and a congestion level of the WLAN in order to increase the quality and the number of calls on a BSS. Paramters such as codec and packetization periods are selected for the call based upon the priority and congestion level. As the level of congestion in the network Increases, only calls above a certain Priority level are allowed into the network.
