Neste trabalho é apresentado o desempenho do teletráfego de uma estrutura de microcélulas e macrocélulas hierarquicamente sobrepostas em um ambiente PCS. Neste sistema, cada grupo de N microcélulas é sobreposto exclusivamente por uma macrocélula. A camada de microcélulas é dedicada a usuários de baixa mobilidade e a camada de macrocélulas é dedicada tanto a usuários de alta mobilidade quanto a usuários de baixa mobilidade com excesso de microcélulas. Em geral, a terminação forçada é consideravelmente indesejável do ponto de vista do utilizador em comparação com a ocorrência de bloqueio de chamadas. Portanto, as chamadas de handoff recebem prioridade de acesso aos canais na camada macrocélula. Como esquema prioritário no nível de macrocélulas, é proposto um esquema de compartilhamento parcial de buffer (PBS). Como medidas de desempenho, são derivadas a probabilidade de bloqueio de chamadas, a probabilidade de terminação forçada e o tráfego transportado. Os efeitos dos tamanhos de uma macrocélula e da estrutura hierárquica da célula no desempenho do sistema são discutidos. O desempenho do esquema PBS também é comparado com o do esquema sem prioridade (NPS) e do esquema de filas por ordem de chegada (FCFS). Os resultados numéricos mostram que o esquema PBS apresenta o melhor desempenho para tráfego de handoff entre os três esquemas.

Abstract: In this work, teletraffic performance of a hierarchically overlaid microcell and macrocell structure in a PCS environment is presented. In this system, each group of N microcells is overlaid exclusively by one macrocell. The microcell tier is dedicated to low-mobility users and the macrocell tier is dedicated to both high-mobility users and overflowed low-mobility users from microcells. In general, forced termination is considerably undesirable from the user's viewpoint compared with the occurrence of call blocking. Therefore, handoff calls are given access priority to channels at the macrocell tier. As a priority scheme at the macrocell tier, a partial buffer sharing (PBS) scheme is proposed. As performance measures, call blocking probability, forced termination probability, and carried traffic are derived. Effects of the sizes of a macrocell and of hierarchical cell structure on system performance are discussed. The performance of the PBS scheme is also compared with those of the no priority scheme (NPS) and the first-come-first-service (FCFS) queueing scheme. Numerical results show that the PBS scheme gives the best performance for handoff traffic among the three schemes.
