In this paper, we propose an improved CDMA/PRMA protocol named CDMA/CAC (Code Assignment Control). In the proposed protocol, each terminal can be assigned spreading code by simple control before packet transmission. We introduce the permission probability for code request. The permission probability for code request restricts the number of terminals requesting code in order to avoid the collision of request signal adaptively to traffic load. In the proposed protocol with enhanced mode, the voice terminals have priority in initial access by setting the permission probability to 1. Also in this protocol, the data terminals can transmit packets continuously if necessary. We carry out the performance evaluation of the protocols by computer simulation and confirm their validity.
