Mechanism for alarm management of Femto related systems to avoid alarm floods

摘要

A method of alarm management in a communications system having a number of Femto base stations, the method comprising the steps of: detecting disruption of a communication link between a Femto base station and a management system via which alarms are communicated; blocking the sending of alarms by the Femto base station; generating a report representative of the accumulation of alarms; detecting re-establishment of the communication link; sending the report to the management system; and reporting alarms to the management system on the basis of the report.
