| Abstract: | 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. |
