In this paper, we propose a slot assignment scheme for integrated voice and data traffic in reservation multiple access protocols. In the proposed scheme, a voice packet does not contend with a data packet and takes over the slot which is previously assigned to a data packet. Thus, a larger number of voice terminals can be accommodated without degradation of quality and throughput even in the situation that data were integrated. We evaluate the voice packet dropping probability, throughput and packet delay through computer simulation. The results show that the proposed scheme has better performance than the conventional PRMA and DQRUMA systems.
