Spatial Traac Estimation and Characterization for Mobile Communication Network Design

This paper presents a new method for the estimation and characterization of the expected teletraac in mobile communication networks. The method considers the teletraac from the network viewpoint. The traac estimation is based on the geographic traac model, which obeys the geographical and demographical factors for the demand for mobile communication services. For the spatial teletraac characterization, a novel representation technique is introduced which uses the notion of discrete demand nodes. We show how the information in geographical information systems can be used to estimate the teletraac demand in an early phase of the network design process. Additionally, we outline how the discrete demand node representation facilitates the application of demand-based, automatic mobile network design algorithms.
