  • System and method for defining an urgency class of a disorder appearing in a communication system station
    Patent number: 5974313
    Abstract: A system and method for determining an urgency class of a disturbance occurring in a base station of a cellular communication system. A list of possible disturbances that can emerge during the functioning of the base station and the preliminary urgency classes determined for the disturbances concerned is maintained in a memory. In order to enable more accurate urgency classification, a preliminary urgency class is searched out from the memory corresponding to disturbances in question. An alarm urgency class is conditioned with the communications state of the base station by detaining a less urgent class than the preliminary urgency class when the communications state of the base station is peaceful (i.e., not busy). When the communication state of the base station is busy, a more urgent class than that of the preliminary urgency class is determined for the alarm.
