<p>Disclosed is a CDMA system and a method of detecting a faulty mobile device in which interference with communication of other mobile devices can be decreased by detecting the existence of a mobile device with a faulty receiver system through monitoring the transmission power of the outgoing signal transmitted from a base station to the mobile device and preventing unnecessary increase in the outgoing transmission power due to an increase request of the outgoing transmission power from the faulty mobile device. The base station reports to a base station controller the transmission power of the outgoing signal transmitted to the mobile device. The base station controller judges the mobile device as faulty when the transmission power of the outgoing signal exceeds the predetermined threshold value for a predetermined period of time, and registers the faulty mobile device to the mobile device managing database. The base station controller sets a desired communication quality for the mobile device lower than the regular quality at the time of an access request. When a request for increase in the outgoing transmission power continues even after degrading the desired communication quality of the mobile device, the base station controller rejects an access request from the faulty mobile device. <IMAGE></p> |
