摘要 针对CDMA2000 1X EV-DO无线接入环境,采用数学分析方法试图对互联网协议多媒体子系统(IMS)中的用户会话建立时延进行定量分析.详细分析了无线链路协议在数据链路层上产生的传输时延,同时分析了上层重传机制对传输时延的影响.分析结果表明,数据链路层使用无线链路协议、传输层使用用户数据报协议、应用层使用会话初始化协议所产生的会话建立时延最小. With code division multiple access 2000 1X evolution data optimized standard for wireless transmission,the session setup delay in internet protocol multimedia subsystem is analyzed by using mathematical analysis quantitatively.The produced transmission delay in date link layer is discussed used with radio link protocol,as well as the transmission delay produced by the retransmission scheme of upper layers.Analysis shows,the session setup delay becomes shorter when radio link protocol is used in date link layer,the datagram protocol is used in transport layer,and the session initiation protocol is used in application layer.
