摘要
Abstract
With the development of Voice over Internet Protocol( VoIP) technology,VoIP technology has been more and more widely used in conjunction with satellite communication networks. Inmarsat satellite system is a geosynchronous orbit system and the propagation delay of network is large,so the feasibility of voice communication of satellite VoIP phones is worth studying. According to the key technologies of VoIP and the application scenarios of Inmarsat satellite communication voice communication,the scheme of im-plementing VoIP technology in the Inmarsat satellite network is discussed,and analysis shows the one-way delay call process of VoIP system is 350 ms,lower than ITU G. 114's 400 ms. Test of the scheme in real environment demonstrates its feasibility. The scheme with low realization complexity can easily achieve the interoperability between Inmarsat network and land telephone network. It can also provide reference for the implementation of VoIP technology in China's own broadband satellite communication system.关键词
