话音/数据综合的多时隙预约多址协议及其性能分析

本文提出了一种综合话音和数据的多时隙预约多址协议.该协议在保证话音终端的优先权的情况下,允许数据终端在报文的传输期间在连续多个帧中预约多个信息时隙.文中对协议进行了理论分析,并推导出了协议的重要性能指标(如话音分组丢失率、数据报文平均接入时延、系统平均吞吐率等)的解析表达式.研究表明,该协议可以支持比IPRMA、NC-IPRMA更高的等效数据终端速率,而且系统平均吞吐率在很大的负载范围内接近最大值.

Integration of Voice and Data over Multi-Slot Reservation Multiple Access Protocol and Its Performance Analysis

A multi slot reservation multiple access protocol is proposed in this paper,which can integrate voice and data services efficiently.Under the condition of giving high priority to voice terminals,data terminals are allowed to reserve multiple information slots in consecutive time frames.The protocol is analyzed by embedded Markov process,from which some important performance measures such as voice packet loss rate,average channel access delay of data messages and system throughput are formulated.The research results indicate that,compared with IPRMA and NC IPRMA,the protocol can support much higher equivalent data terminal rate,and within a large extent of traffic loads,the maximum system throughput can be reached.
