Method and apparatus for reducing access delay in push to talk over cellular (PoC) communications

摘要

A method and apparatus for reducing access delay in push-to-talk (PTT) over Cellular (PoC) communication sessions is provided in a wireless communication device ( 120 ) including a quality level controller ( 230 ) which controls the quality level at which the transmit talkburst controller ( 226 ) provides talkbursts to transmitter circuitry ( 206 ). A processor ( 208 ) signals the quality level controller ( 230 ) and the transmit talkburst controller ( 226 ) to provide a first talkburst to the transmitter circuitry ( 206 ) for transmitting at a first quality level ( 310 ), and thereafter signals the quality level controller ( 230 ) to adjust the quality level from the first quality level to a second quality level ( 314 ) so that the transmit talkburst controller ( 226 ) will provide at least one subsequent talkburst to the transmitter circuitry ( 206 ) for transmitting at the second quality level ( 316 ).
