Predição de séries temporais de parâmetros de rede WCDMA – HSPA

Abstract

In telecommunications, with the growing demand of data traffic in the networks of third generation (3G), the mobile operators have attempted to focus resources on infrastructure in places where it is identified a greater need. The channeling investments have the goal of maintaining quality of service, especially in dense urban areas. In this work, the prediction of time series in WCDMA networks is carried on for the parameters: received power (Rx Power), Received Signal Code Power (RSCP), Energy per chip/Interference (Ec/Io) and throughput at the physical layer. The collection of parameters values was performed on a fully operational network through a drive test in Natal/RN. The model used to predict the time series was the model of Holt exponential smoothing. The objective of the predictions of the series is to check which parameters HSPA network - WCDMA model best adapted Holt
