摘　　要：通过对现有标准SIP协议进行分析,根据卫星通信带宽昂贵、时延大的特性,提出几种优化语音呼叫协议;对这几种语音呼叫协议进行详细分析以及进行仿真,找到一种适合宽带卫星通信系统中的卫星呼叫协议;以降低会话管理在卫星网络下的时延和带宽,加快语音起呼过程,减少系统信令开销,进而提高实时性以及语音成功率.Considering the high bandwidth and time-delay in the satellite communication,several optimized voice call protocols were proposed.The several voice call protocols were analyzed and simulated.A suitable satellite call protocol is wished to be found for the broadband satellite communication system,which will reduce the time delay and bandwidth of session management in satellite network,speed up the voice call process,reduce the system signaling overhead,and then improve the real-time performance and the success rate of voice call.
