Dans ce travail, les performances de télétrafic d'une structure de microcellules et de macrocellules superposées hiérarchiquement dans un environnement PCS sont présentées. Dans ce système, chaque groupe de N microcellules est recouvert exclusivement par une macrocellule. Le niveau microcellule est dédié aux utilisateurs à faible mobilité et le niveau macrocellule est dédié à la fois aux utilisateurs à haute mobilité et aux utilisateurs à faible mobilité débordés des microcellules. En général, une terminaison forcée est considérablement indésirable du point de vue de l'utilisateur par rapport à l'apparition d'un blocage d'appel. Par conséquent, les appels de transfert bénéficient d'une priorité d'accès aux canaux au niveau macrocellule. En tant que schéma prioritaire au niveau macrocellule, un schéma de partage partiel de tampon (PBS) est proposé. En tant que mesures de performances, la probabilité de blocage d'appel, la probabilité de terminaison forcée et le trafic acheminé sont dérivés. Les effets de la taille d'une macrocellule et de la structure hiérarchique des cellules sur les performances du système sont discutés. Les performances du système PBS sont également comparées à celles du système sans priorité (NPS) et du système de file d'attente premier arrivé, premier service (FCFS). Les résultats numériques montrent que le schéma PBS donne les meilleures performances pour le trafic de transfert parmi les trois schémas.

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.
