SYSTEM AND METHOD FOR CHANNEL ASSIGNMENT WITH A FORWARD AND BACKWARD REASSIGNMENT STEP

摘要

A method (40) and device (42) for assigning transmission channels in a wireless communications network (38). The frequencies of the network (38) are discriminated to determine which transmission channels have a predetermined blocking threshold of interference. A transmission channel is preassigned with a channel quality less than the predetermined blocking threshold of interference to an incoming call. The channel quality and interference level of the preassigned transmissions channel are continually monitored, and another transmission channel is assigned to the call when the monitored levels of channel quality and interference levels change beyond a set of predetermined thresholds. Forward and backwards channel reassignments are performed depending on the channel quality and interference levels.
