Abstract: The good development trend of IP service terminal has laid a powerful foundation for the development of satellite communication system. In the satellite emergency communication system based on the satellite IP network, the telephone soft switch technology makes the satellite narrowband voice, VoIP voice and traditional PSTN voice communicate, which makes the satellite emergency voice communication IP and wireless. This paper discusses the application of softswitch technology in satellite IP network to promote the  capability of satellite communication voice service.

Key words: satellite communication; IP service; soft switch technology

1  研究背景

在目前的卫星通信应急系统中,通常有模拟语音、IP语音及传统的PSTN有线语音,相对而言,由于各系统语音编解码方式不相同、传输速率不相同,呼叫的接续流程独立。(剩余3824字)
