Abstract
Malfunctioning or misbehaving mobile stations, that are capable nonetheless of continuing to communicate with a wireless communication system, are detected for the purposes of either shutting down misbehaving mobile stations or reporting misbehaving mobile stations so that corrective action can be taken. An error detector and interpreter detects in wireless communication signals received from a mobile station any breach of protocol errors indicative of faulty operation of the mobile station. A misbehavior analyzer analyzes the errors over time to determine whether the mobile station is misbehaving. Normal access of the mobile station to the wireless communication system is shut down or a message is sent to the subscriber in the event the mobile station is determined to be misbehaving. The mobile station also has a shutdown mode of operation, controllable by a message sent from the network, in which the mobile station remains idle and non-functional until repaired. The quality of service to subscribers using the wireless communication system is thus improved.
