Previous issue date: 2014-06-10 / Com o crescimento da demanda de tr?fego de dados nas redes de terceira
gera??o (3G), as operadoras de telefonia m?vel t?m atentado para o direcionamento dos
recursos em infraestrutura nos locais onde se identifica maior necessidade. O
direcionamento desses investimentos tem o objetivo de manter a qualidade do servi?o
prestada principalmente em regi?es urbanas densas. Neste trabalho ? realizada a
predi??o de s?ries temporais em rede WCDMA - HSPA dos par?metros Rx Power,
RSCP (Received Signal Code Power), Ec/Io (Energy per chip/Interference) e taxa de
transmiss?o (throughput) na camada f?sica. A coleta dos valores dos par?metros foi
realizada numa rede em pleno funcionamento atrav?s de um drive test na cidade de
Natal ? RN, uma capital do nordeste brasileiro. Os modelos utilizados para predi??es
das s?ries temporais foram os de Alisamento Exponencial Simples, Holt, Holt-Winters
Aditivo e Holt-Winters Multiplicativo. O objetivo das predi??es das s?ries temporais ?
verificar qual modelo ir? gerar as melhores predi??es dos par?metros da rede WCDMA
- HSPA. / 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 identifies a greater need. The channeling investments aim to maintain the
quality of service especially in dense urban areas. WCDMA - HSPA parameters Rx
Power, RSCP (Received Signal Code Power), Ec/Io (Energy per chip/Interference) and
transmission rate (throughput) at the physical layer are analyzed. In this work the
prediction of time series on HSPA network is performed. The collection of values of the
parameters was performed on a fully operational network through a drive test in Natal -
RN, a capital city of Brazil northeastern. The models used for prediction of time series
were the Simple Exponential Smoothing, Holt, Holt Winters Additive and Holt Winters
Multiplicative. The objective of the predictions of the series is to check which model
will generate the best predictions of network parameters WCDMA - HSPA.
