摘　　要：软交换呼叫服务器的数据吞吐量十分巨大,影响电信网络通信性能。目前的研究大多局限于通过加大网络传输能力以及采用负荷分担的形式来减轻负荷。该文针对软交换中呼叫服务器的备份过程,改进了备份系统模型,并将提取/恢复函数引入呼叫服务器的备份系统,有效地提高了主备板之间的备份效率,从而提高了呼叫服务器的可靠性。The traffic load of softswitch call server is huge which influences the performance of telecommunication network. Currently, researches are mainly confined to reducing load by increasing the net ：ransmission capability or sharing load. Aiming at the back-up process of call server in NGN, this paper proposes an improved model of backup system which effectively enhances the backup efficiency between active board and standby board of call server. The result of test and analysis is presented.
