A requesting handset in a wireless communication network sends a call
message requesting a push-to-talk connection with a target handset. In
response, a push-to-talk server sends a connection status message to the
requesting handset. The connection status message is sent to the
requesting handset in a control channel such as the forward common
control channel. The requesting handset indicates to the caller that the
connection has been made with the target handset, turns on the audio
channel, and buffers any audio received from the caller until the traffic
channel has been established. Once the traffic channel is established,
any buffered audio is sent over the traffic channel and the push-to-talk
call ensues.
