heal.abstract	In this paper a multiple access protocol and a call acceptance algorithm for voice and data integration in a microcellular mobile communication system is presented. The protocol supports three service classes, namely, circuit-mode voice, burst-mode voice, and data. A hybrid multiplexing scheme with no boundaries is employed, which performs statistical multiplexing of connections of three classes at two different levels, the call-level (for circuit-mode voice) and the talkspurt/message-level (for burst-mode voice and data). This scheme achieves high utilization of the available bandwidth compared to the pure-circuit-switching scheme. The penalty paid is a lower quality in the latter two classes, due to the delay experienced during channel access on each talkspurt/message. A two-party transaction modeling for each class is implemented giving a realistic load on uplink and downlink. Data messages are segmented before transmission and a lower priority of the preemptive type at segment boundaries is assigned to them, in favor of the voice talkspurts transmission. A unified access procedure is presented and the structure of the required control bursts is described. To manage with the apparent system complexity, a simulation tool has been developed in SIMSCRIPT II.5 for performance analysis. With the requirement to satisfy certain quality-of-service limits, the optimum data-segment size is obtained. The maximum acceptable load is determined for various traffic mixes, given in the form of acceptable regions in the load space. Based on these regions, a call acceptance algorithm is implemented and typical simulation results on delay and call blocking are given.	en
