New applications put out by the service providers require high data rates in order to enjoy the best performance of its functionalities, hence to have a good Quality of Service (QoS). To provide the system with a solution to enable a good service to user equipments one can adopt the HCS (Hierarchical Cell Structure) model. The model is considered to improve the system’s capacity, coverage and quality of service. In this paper, several HCS scenarios are implemented over the UMTS, HSDPA and HSUPA technologies. Four distinct profile users are considered and a snapshot method was used to simulate the mobile users. The scenarios are individually analyzed and submitted to performance comparisons. The results show that the deployed scenario with higher number of co-located cell partitions is the one that provides a higher system capacity, i.e. better cell throughput, and also higher service rates (near 95%). The model with cell-edge topology allowed the increase of the inter-cell area throughput.
