摘　　要：随着移动卫星通信和地面移动通信的发展,融合两种通信网络,成为移动通信网络的重要研究方向。在"天通一号"移动卫星通信网络和地面移动通信网络的话音业务融合中,需要解决移动卫星通信网络中电路域话音与地面移动通信网络中VoIP话音相互融合的问题。本文提出了一种利用网关实现卫星通信电路域话音与VoIP相互融合的方式,并以开源软件Asterisk、卫通模块为基础,在嵌入式Linux平台上,完成了卫星通信电路域话音与VOIP融合的实例。With the development of mobile satellite communication and terrestrial mobile communication,the integration of the two communication networks has become an important research direction on mobile communication networks.In the convergence of voice service of"Tiantong-1"mobile satellite communication network and terrestrial mobile communication network,it is necessary to solve the problem of the fusion of circuit domain voice in mobile satellite communication network and VoIP voice in terrestrial mobile communication network.This paper presents a way to realize the fusion of satellite communication circuit voice and VoIP by using the gateway,and based on the open source software Asterisk and satellite communication modules,an example of the fusion of satellite communication circuit domain voice and VOIP is completed on the embedded Linux platform.
