Gestão de desempenho numa rede celular

Abstract

A realização desta dissertação tem como principal objetivo a análise de indicadores chave de desempenho numa rede celular de terceira geração - Universal Mobile Telecommunication System (UMTS), bem como a aplicação de técnicas matemáticas de previsão como apoio ao respetivo planeamento e otimização. Para o efeito, foi inicialmente efetuado um estudo sobre a evolução das comunicações de uma forma generalista, até às redes de nova geração, abordando individualmente, as de voz, as de dados e as comunicações móveis, assim como, uma breve descrição das organizações envolvidas nestas mudanças. No seguimento do estudo inicial, dando enfoque à tecnologia UMTS, foram expostas as suas características, a sua estrutura e arquitetura. Foram ainda elaboradas, duas comparações, com base em diferentes parâmetros, uma com a tecnologia da geração anterior e outra, com a de última geração. Com base nos conhecimentos adquiridos em diferentes pesquisas, foram estudados, os indicadores chave de desempenho (KPIs), as técnicas de planeamento e otimização, apresentando propostas de prevenção e soluções para problemas existentes na rede.

This dissertation aims to analyze key performance indicators in a third generation cellular network - Universal Mobile Telecommunication System (UMTS), as well as the application of mathematical forecasting techniques to support their planning and optimization. Towards this aim, a study was initially performed, in a general overview, regarding the development of communications until the newest network, addressing individually, voice, data and mobile communications, as well as a brief description of the organizations involved in those changes. Following that study and focusing on UMTS technology, its main characteristics, structure and architecture were exposed, ending the evaluation with two comparisons, based on different parameters, one with the previous generation technology and the another with the latest generation. Based on the knowledge acquired in various researches, key performance indicators (KPIs), technical planning and optimization have been studied, while presenting proposals to prevent unwanted situations and displaying solutions to existing problems in the network.
