Abstract In this paper, a new packet medium access control protocol, namely, Minislot Sig-naling Access based on Distributed Queues protocol is proposed in voice and data integration CDMA network (MSADQ/CDMA). Through proper manage of the PN codes, the number of random competition collisions reduces greatly, the Multiple Access Interference (MAI) de-creases, and the code resources are saved. Computer simulations are carried out in voice and data integration networks, and comparisons with other two reservation protocols are devel-oped, which show that MSADQ/CDMA protocol occupies less PN codes, but still has very good performance.
