A new dynamic reservation multiple access protocol for supporting multimedia traffic in third generation cellular system

A dynamic reservation multiple access (D-RMA) protocol for future third generation cellular mobile radio systems, which is explicitly designed for supporting multimedia traffic, is proposed and its behavior is investigated under variable traffic conditions. Its structure is based on traditional PRMA++ protocol. In addition to PRMA++, a dynamic adaptation of percentage of bandwidth to use for reservation within a frame to traffic condition, is permitted, this having the main goal to guarantee the required grade of service (GoS) to multimedia services. The goal is also achieved by providing for a suitable bandwidth allocation strategy, which assigns to different broadband services a different amount of frequency resource, and by coupling it with a suitable management scheme for the base station reservation buffer. Obtained results show that performance of D-RMA protocols are superior when compared with a traditional “non-dynamic” protocol, both in terms of offered GoS to carried services and number of activable connections in a microcell at the same time
