A TMN framework for faults diagnostic in wireless telecommunication networks

The occurrence of a fault in a critical component of large telecommunication system may cause multiple abnormal situations leading to large number of different alarms at different locations. Appropriate management tools are required to automatically filter and correlate these alarms in order to localize faulty components. Such tools must be based not only on the description, state and behavior of the managed components, but also on explicit description of the dynamic state and behavior of the relationships between these components. The paper explores the usage of relations between wireless network managed components within a TMN based framework. The proposed framework is used in the design of a TMN based fault management system including alarms correlation and fault diagnostic for wireless networks
