摘　　要：为实现灵活、畅通、可靠的井下通信,设计一种基于嵌入式Linux的移动会话初始协议(SIP)通信终端。该终端利用SIP作为应用层协议,在流动会话过程中提供对语音连续性的支持。设计一种灵活高效的SIP协议栈,在嵌入式平台下结合无线局域网技术,实现井下实时语音通话功能。实验结果表明,该终端通话质量较好。According to the current mine safety and actual needs,this paper introduces a design of mobile Session Initiation Protocol（SIP） communication terminal unit based on embedded Linux.The terminal uses SIP as application-layer protocol which provides the liquidity support for voice continuity during an ongoing session,and designs a flexible and efficient SIP protocol stack which implements in the embedded platform with wireless LAN technology to achieve real-time voice calls under-mine.Experimental results show that the terminal has good calls quality and a broad application and promotion aspects in improving underground communications and other functions.
