Abstract
The Universal Mobile Telecommunications System (UMTS) will provide multimedia services to users in whatever environment via uniform service access procedures. Efficient Medium Access Control (MAC) protocols are needed to guarantee high capacity. This paper deals with Packet Reservation Multiple Access (PRMA), an efficient MAC protocol that has been widely studied in terrestrial microcellular systems. We investigate the suitability of PRMA for supporting voice and data transmissions in a UMTS based on Low Earth Orbit - Mobile Satellite Systems (LEO-MSSs). It is shown here that, through a suitable choice of the system parameter values, the PRMA protocol may achieve a good quality of service also in LEO-MSSs.
