Patent ID: 7187713

Claim:
A method for intelligent selection of a warm start in a modem comprising the steps of: terminating a modem connection once the need to terminate the modem connection has been recognized; capturing an initial condition of a communications channel that carried the modem connection and storing same as a profile of an initial profile of channel condition; setting a timer; and waiting for the timer to expire and while the timer has not yet expired, determining if the modem connection needs to be re-established; if the timer has expired and there is no need to re-establish the modem connection: capturing a current condition of the communications channel and storing same as a profile of current channel condition; and resetting the timer; and if the modem connection needs to be re-established: retrieving the initial profile of channel condition from storage; retrieving the current profile of channel condition from storage; initiating a warm-start sequence if the difference between the initial profile of channel condition and the current profile of channel condition does not exceed a variation threshold; and initiating a cold-start sequence if the difference between the initial profile of channel condition and the current profile of channel condition exceeds the variation threshold.
