Patent ID: 7561552

Claim:
A method for adaptive channel signaling for a traffic channel with a mobile unit in a mobile communication system, the method comprising the steps of: determining whether a control message is a critical message; determining whether the control message is a retransmission; if the control message is the critical message, determining whether the traffic channel is operating at a subrate indicating that the speech level on the traffic channel is reduced; if the traffic channel is operating at the subrate, sending the critical message and a number of fast repeats of the critical message on the traffic channel; if the control message is the retransmission, the number of fast repeats of the critical message on the traffic channel to the mobile unit being an increased number of fast repeats that is greater than the number of fast repeats of the critical message; and if the control message is the retransmission and the traffic channel is not operating at the subrate, the number of fast repeats of the critical message on the traffic channel to the mobile unit being a nominal number of fast repeats that is less than the number of fast repeats.
