Audio codec bit-rate control method for assuring qos of voice in wlan
TLDR
In this paper, a method and apparatus for controlling voice quality in WLAN is provided, where the bit rate of wireless terminals is adjusted by collecting channel state information for determining a channel occupation time of the wireless terminals connected to an access point.Abstract:
A method and apparatus for controlling voice quality in WLAN is provided. The codec bit rate of wireless terminals is adjusted by collecting channel state information for determining a channel occupation time of wireless terminals connected to an access point, adjusting the codec bit rate of the wireless terminals based on channel occupancy of the wireless terminals with respect to total channel capacity, which is determined using the channel state information, and transmitting the adjusted codec bit rate to each of the wireless terminals.read more
