基于SIP的矿用应急通信业务系统设计

摘要

The paper designed a mine-used emergency communication service system based on SIP,described designs of the system architecture and business processes including emergency call,region location of communication terminal,multi-channel intercom and voice broadcast.The system follows the standard SIP protocol and its extension framework proposed by 3GPP,realizes highly integrated mine-used dispatching communication and emergency communication service system,which provides effective contact means and communication protection,and improves comprehensive utilization of underground communication system.%设计了一种基于SIP的矿用应急通信业务系统,详细介绍了系统架构设计及紧急呼叫、通信终端区域定位、多路对讲和语音广播等业务流程的设计.该系统遵循标准SIP协议及3GPP提出的标准SIP协议扩展框架,实现了具有较高集成度的矿用调度通信与应急通信业务系统,为矿山井下通信联络、安全生产提供了有效的联络手段与通信保障,提高了井下通信系统的综合利用率.
