摘要
本文提出了利用用户自身信息之间的相关性区分用户，并适当地调整用户再次竞争信道的允许概率，来提高分组预约多址（ＰＲＭＡ）协议中话音业务性能的方法，从仿真的结果看，该方法降低了话音分组的丢失率．
A method (VPPRMA) based on the user's demand to improve the performance of voice service in Packet Reservation Multiple Access (PRMA) system is proposed.After the analysis of PRMA,the new mothod,using variable contending probability according to the actual condition,is presented.According to the simulation,the probability of packet dropping is reduced.
