Abstract: Statistical processing of event outcomes, such as call attempts or handoff attempts, allows reliable generation of performance alarms within a communication network without requiring analysis of historic performance data. Base station controllers might implement such statistical processing so that the controllers themselves rather than other, further removed network management entities generate performance alarms. Attendant advantages include but are not limited to relatively fast and reliable alarm generation using relatively small sample sets. These and other advantages permit detecting and reporting performance alarm conditions more quickly without sacrificing alarm generation reliability.
