DEVICE, SYSTEM AND METHOD FOR HANDLING ALARM MESSAGE STORMS IN A COMMUNICATIONS NETWORK

摘要

For improving handling of alarm message storms in a communications network, alarm message storm avoidance, detection and/or recovery are implemented at nodes (23) and/or at data traffic controlling nodes (3, 20, 22) of the communications network. For alarm message storm avoidance, a random time spreading of alarm message transmissions is proposed, wherein the random time spreading of alarm message transmissions can be based on the current context and/or node state. For alarm message storm detection, it is proposed to monitor the alarm message inflow frequency to trigger a recovery process, wherein the monitoring can be performed with regard to different alarm types, parts of the network and/or time periods locally and/or centrally. The alarm message storm recovery or processing, respectively, is implemented by suppressing the amount of alarm messages to be transmitted. The alarm message storm recovery or processing can be implemented in a centralized and/or in a distributed way.
