井下移动SIP通信终端的设计与实现
Design and Implementation of Mobile SIP Communication Terminal Under Mine
摘要
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.关键词
