ABSTRACT:
A method of using control channel information is provided to enhance data throughput of a cellular communication system. The cellular communication system includes a single system control unit coupled to a data pump, a cellular transceiver and a radio transceiver. A method of operating the cellular communication system includes the following steps: (a) detecting a control channel signal indicating that a channel interruption is to occur; (b) decoding the control channel signal; (c) sending the decoded control channel signal to the system control unit; (d) controlling the parameters of the adaptive components of the data pump so that the parameters remain at a converged state or are adjusted even during the channel interruption; (e) interrupting the channel; and (f) re-establishing the channel within a reduced retraining time period. Before interrupting the channel, the cellular communication system may also transmit a command to a data pump of a remote modem so that the remote modem can initiate an appropriate process to maintain the parameters of its adaptive components at a converged state or to adjust the parameters continuously during the channel interruption. The cellular communication system may also acknowledge receiving the control channel signal before the channel is interrupted.
