摘　　要：本文在分析分组预约多址(PRMA)协议的基础上,从用户角度和实际通信情况考虑,提出了基于补偿性参数作为系统的性能参数,并采用适当加大用户再次竞争信道的允许概率来提高PRMA系统中话音业务性能的方法(VP-PRMA),从计算机仿真的结果看,该方法对提高PRMA系统中话音业务的性能确有帮助。A method (VP-PRMA) based on the users' demand to improve the performance of voice service in PRMA system is proposed. In the paper, a new system measurement based on relative penalty factor is used. After the analysis of PRMA, the new method, using variable contend probability according to the actual condition, is presented. According to the simulation, the proposed method improves the voice performance as expectated.
