A method is provided in a network management node for handling an alarm caused by a fault in a communications system. An alarm caused by a fault in the communications system is received from a first network element within the communications system. The alarm is associated with an identity of the first network element, and an alarm time associated with the time when the alarm was active. After receiving the alarm, the network management node sends a request to a user activity database, requesting one or more matching records. Each of the matching records is requested to comprise an identity equal to the identity of the first network element associated with the alarm, and a record time period that comprises the time when the alarm was active. The network management node receives one or more matching records from the user activity database, which one or more matching user session records identify the user sessions being affected by the alarm, and then handles the alarm based on the one or more matching user session records.
