<p>The present invention is directed to method and apparatus for detecting base station (BS (18)) transceivers (19) malfunctions in a cellular telecommunications system (10). A Transceiver Malfunction Detector (TMD (25)) receives and stores (37) information related to the service performance of the BS transceivers and sorts (40) the information on a per transceiver basis, for generating a service quality value for each transceiver. The TMD computes a service quality threshold value (42) proportional to the average performance of the BS transceivers, and compares (54) the service quality value of each monitored transceiver with the threshold, for determining the acceptability of the transceiver performance. The TMD also detects the cause of a malfunction in a transceiver, by assigning (74) the frequencies used by an adequate transceiver to a transceiver suspected to be malfunctioning and by further monitoring (76) the activity of the initially malfunctioning transceiver. When the transceiver persists malfunctioning after the frequency change, it is concluded (82) that the malfunction is due to a hardware or software problem in the transceiver, while if the transceiver performance improves after the frequency change, it is concluded (80) that the malfunction is due to a frequency interference.</p> |
