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 by determining whether the change in the traffic pattern over a short period of time is excessive, determines whether the abnormality is due to the faulty mobile unit or a problem with the wireless network by examining conditions of the traffic, 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.

L'invention a trait à un dispositif permettant d'isoler, dans un réseau de transmissions sans fil possédant plusieurs unités mobiles opérant dans une de ses cellules, une unité mobile défectueuse brouillant le canal de commande et empêchant, de ce fait, les autres unités mobiles de communiquer à l'intérieur de la cellule. Le dispositif d'isolation d'unité mobile défectueuse, qui surveille le courant de trafic de cellule existant entre les unité mobiles à l'intérieur de la cellule, juge si l'anomalie est due à l'unité mobile défectueuse ou à un problème relevant du réseau de transmissions sans fil. S'il s'avère que l'unité mobile défectueuse est responsable de cette anomalie, ce dispositif entre en communication avec les unités mobiles opérant à l'intérieur de la cellule afin d'isoler cette unité mobile défectueuse.
