This paper presents a technique for evaluation of future radio traffic of circuit switched services in Erlang for near-term outlook using Holt-Winter's exponential smoothing. The proposed traffic prediction technique relies on analysis of traffic data on cells. We propose how to classify traffic data for prediction. The result from a trial in history data(More)
In this paper, we present an automated troubleshooting method for mobile networks based on alarm and performance data using two Bayesian Networks. The method provides online, reactive diagnosis of malfunction alarms using the Bayesian Network with alarm correlation and diagnosis of cells' bad performance using another Bayesian network. The proposed method(More)
