Abstract(s)
In order to survive in a highly competitive market, mobile network operators have to be as efficient as possible in managing their resources. This is particularly relevant in what concerns the capacity available at their sites. This work aims to give the operators a method to improve longevity of their sites. This was achieved using a Load Balancing algorithm, which takes into consideration the Channel Element usage of sites and sets an Received Signal Code Power threshold value for each one. Its evaluation is done by using a Traffic Forecast algorithm, based on a fitting method, in order to obtain an estimate of when the sites' capacity limit is reached, before and after applying Load Balancing. The used input data consisted of real traffic statistics, including geo-located indicators. During the course of this work it was possible to develop a semi-automatic method for network optimization using geo-located data, thus making a contribute to the development of national research on Self-Organizing Networks. This project was developed in collaboration with a Portuguese telecommunications consulting company, Celfinet, which provided valuable supervision and guidance. Using the suggested method it is predicted that, after a year of implementation, it is possible to achieve savings of about 70% in capacity expansions in the network.
