A Non-Collision PRMA Protocol for Integrated Voice and Data Wireless Networks - Universal Personal Communications. 1995. Record., 1995 Fourth IEEE International Conference on

A key to integrate voice and data traffic onto a common radio channel is the silence gaps detection technique. By restraining the voice terminals while silence from occupying the slots, the system capacity can be significantly improved. This paper considers the integrated voice/data services using NC-PRMA protocol in which the silence gaps detection technique is provided. Also, two additional strategies are applied to this protocol for the purpose of improving system performance: (1) to limit the number of slots shared by the voice terminals as less as possible subject to the packet dropping rate no more than 0.01; (2) to dynamically control the data terminals to share all of the unused time slots in a "round robin" manner. Based on these strategies, the performance of movable boundary and no boundary slot assignment schemes are analyzed. The performance is measured in terms of the blocking probabilities of voice and data terminals and the mean transmission time of data terminals. The results show that, on the basis of voice and data traffic are the same, the no boundary scheme performs better than the movable scheme does.
