Abstract
A wireless network, having a plurality of mobile units operating in a cell of the wireless network, isolates a faulty mobile unit that jams the control channel thereby preventing communication by the other mobile units in the cell. A system and method for isolating the faulty mobile unit monitors the cell traffic pattern among the mobile units in the cell to detect an abnormality, determines whether the abnormality is due to the faulty mobile unit or a problem with the wireless network, and if the abnormality is due to the faulty mobile unit, communicates with the mobile units operating within the cell to isolate the faulty mobile unit.
